<div>Background: Supplementation of urea molasses mineral block (UMMB) showed promising results in improving the nutrient utilization and the productivity of animals. This offers several advantages such as easy transport, storage and handling and reduced risks of poisoning as compared with other approaches, such as giving a small amount of urea in drinking water, sprinkling of urea solution on fibrous feeds before feeding, or urea-ammonization of crop residues. These advantages of solid multi-nutrient blocks (SMB) opened up new vista to enhance productivity in terms of increased milk and meat production and higher reproductive efficiency in ruminant animal species. Keeping the above facts in view, this study was undertaken to determine the effect of feeding solid multinutrient blocks on feed intake, nutrient utilization and haemato-biochemical profile of crossbred calves 
 
Methods: In this study twenty four crossbred male calves of about 14-17 months of age were divided into four groups of six animals in each group. All animals were supplied wheat straw ad lib. In addition, animals in all groups were fed a concentrate mixture to meet out their nutrient requirement. Additionally, 30 % of concentrate mixture (on CP basis) was replaced by solid multi-nutrient blocks (SMB-I), SMB-II and SMB-III in groups T1, T2 and T3, respectively. After 60 days of feeding a metabolism trial of 6 days was conducted to assess the nutrient utilization of animals. Blood samples were collected at 0, 75, 150 day of experimental feeding to determine hematological parameters, enzymes, biochemical parameters and serum mineral concentration. 
 
Result: The intake and digestibility of DM, OM, EE, NDF and ADF were comparable among 4 groups. The CP intake was significantly higher in SMB supplemented groups as compared to control but there was no significant difference in CP digestibility among 4 groups. All the animals in four groups were on positive nitrogen, calcium and phosphorus balance. Haematobiochemical parameters like Hb, PCV, glucose, total protein, globulin, A:G, SGOT and SGPT showed non-significant differences (p&gt;0.05) among the groups, however, periodical serum concentrations of albumin, urea and creatinine was higher in crossbred calves at 75 and 150 days of experiment in comparison to 0 day. On basis of present results, it may be concluded that supplementation of SMB can replace 30% crude protein of concentrate mixture without any adverse effect on feed intake, digestibility, nutrient utilization and blood biochemical profile of crossbred calves.</div>

Effect of Feeding Solid Multi-Nutrient Blocks on Feed Intake, Nutrient Utilization and Haemato-Biochemical Profile of Crossbred Calves

The experiment was carried out in 12 local adult male goats of average body weights (26.49&plusmn;0.87, kg) and they were allocated in 3 groups (4 goats in each). Multi nutrient blocks (MNB) were supplemented in first two groups i.e. in T1 (no infection) and T2 (Haemonchus contortus infection @ 1500 larvae) group, while, condensed tannins (CT) containing multi nutrient blocks (MNB-CT) were supplemented in T3 (H. contortus infection @ 1500 larvae) group in completely randomized block design during a feeding trial of 75 days. All the animals were fed concentrate mixture @ 100g/ day, adlib wheat straw and MNB or MNB-CT to meet their maintenance requirement. Daily intakes (kg W0.75) of dry matter (DM), organic matter (OM), concentrate mixture, MNB, MNB-CT, wheat straw and digestibility of DM, OM, crude protein (CP) and acid detergent fibre (ADF) differed significantly

<div>Background: A field experiment was conducted during two consecutive Rabi (winter) seasons of 2016-17 and 2017-18 at Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat, India to assess the impact of wheat varieties and integrated nutrient management practices on nutrient content and uptake and soil nutrient status. The soil of the experimental plot was loamy sand in texture, low in organic carbon (0.24%), available nitrogen (159 kg/ha) and Zn (0.41 mg/kg), medium in available phosphorus (38.90 kg/ha) and high in available potash (287 kg/ha). 
 
Methods: Experiment was laid out in a Factorial RBD with three replications, consist of four wheat varieties viz. GW 273, GW 322, GW 451 and GW 496 and six integrated nutrient management (INM) practices viz. control, 100% RDF, 100% RDF + Azotobacter + PSB, 75% RDF + Azotobacter + PSB, 75% RDF + Azotobacter + PSB + ZnSO4 and 50% RDF + 25% N through FYM + Azotobacter + PSB + ZnSO4.&nbsp; 
 
Result: The pooled results indicated that uptake of nitrogen, phosphorus and potassium by grain and straw, grain yield and straw yield were found higher with wheat variety GW 451 as compared to other wheat varieties. Nutrient content in grain and straw was not significantly affected by different wheat varieties. Among nutrient management practices, nitrogen, phosphorus and potassium content, uptake, grain yield and straw of wheat were significantly higher under application of 100% RDF + Azotobacter + PSB. Further, result revealed that different wheat varieties did not bring any significant variation in available nitrogen, phosphorus, potassium, zinc and organic carbon content in soil. Moreover, highest available nitrogen and phosphorus in soil was recorded with the application of 100% RDF + Azotobacter + PSB. However, significantly higher organic carbon and zinc content in soil was observed under 50% RDF + 25% N through FYM + Azotobacter + PSB +ZnSO4.</div>

Effect of Wheat Varieties and Integrated Nutrient Management Practices on Nutrient Content, Uptake and Soil Nutrient Status

<div>Background: The excessive usage of chemical fertilizers and the negligence on soil health regarding the conservation and use of organic sources of nutrients have not only caused the exhaustion of soil nutrient reserves but also resulted in soil health problems which is not conducive to achieving consistent increase in agricultural production. The beneficial influence of organic matter on the physical, chemical and biological properties of the soil is well known, the full appreciation of the same remains which is unfortunately ignored in modern agriculture. The regular recycling of organic wastes in the soil is the most efficient method of maintaining optimum nutrient reserves of soil and nutrient uptake by the plant. The Present Study was conducted to evaluate the nutrient status of soil under integrated usage of organic and inorganic sources. 
 
Methods: A field experiment entitled &ldquo;Nutrient Management Interventions in Rice-Ragi Sequence&rdquo; was conducted during kharif and rabi seasons of 2017-18 and 2018-19 on sandy loam soil of the Agricultural College Farm, Bapatla. The seven treatments consisted of T1: 100% RDF (100-60-40 kg N-P-K ha-1); T2: 100% RDF + Soil application of ZnSO4 @ 50 kg ha-1; T3: 125% RDF+Soil application of ZnSO4 @ 50 kg ha-1; T4: 75% RDF + Poultrymanure&nbsp; @ 0.82 t ha-1 + Soil application of ZnSO4 50 kg ha-1; T5: 75% RDF + FYM @ 5.0 t ha-1 + Soil application of ZnSO4 @ 50 kg ha-1; T6:50% RDF + Poultrymanure @ 1.6 t ha-1 + Soil application of ZnSO4 @ 50 kg ha-1 and T7: 50% RDF + FYM @ 10 t ha-1 + Soil application of ZnSO4 @ 50 kg ha-1. The experiment was laidout in randomized block design with seven treatments and replicated thrice during kharif rice and in rabi each kharif treatment was subdivided into four sub treatments (S1: Nofertilizer, S2: 100% RDF, S3:75% RDF and S4:50% RDF) and hence, The split plot design was adopted in rabi. Total No.of plots per each replication in the rabi was 28 (7x4=28).&nbsp; 
 
Result: Nutrient content and uptake of nitrogen, phosphorus, potassium and zinc have increased significantly with the fertility levels and organics. 50% RDF + FYM @ 10 t ha-1 + ZnSO4 @ 50 kg ha-1 recorded the highest nitrogen, phosphorus, potassium and zinc contents and uptakes in grain and straw of rice. In no till rabi ragi, N, P, K, Zn and calcium content and uptake in grain and straw were found to be significantly superior with 100% RDF (S2) to the rest of the treatments in both the years and in pooled data.</div>

Effect of Nutrient Management Interventions on Nutrient Uptake of Rice-zero Till Ragi under Coastal Lands

<div>A field experiment was carried out during kharif season of 2016 and 2017 at an experimental farm of MACS Agharkar Research Institute, Pune, India to study the influence of foliar application of nutrient on growth, yield, economics, soil nutritional status and nutrient uptake of soybean crop. An experiment was laid out in randomized block design (RBD) comprising of three replications and nine treatments. Recommended dose of fertilizers (RDF) was applied as basal application to all treatments. Seven treatments consisted of different doses of nutrients as foliar application at pod initiation stage. Water spray at pod initiation stage and RDF alone were treated as control. The results revealed that, growth attributes, nodulation and its weight, morpho-physiological parameters, yield and its attributes, nutritional parameters and economics significantly differed by various foliar nutrition treatments except control and RDF + water spray. RDF + Urea 2% (3098 kg ha-1) gave significantly higher seed yield over control (2704 kg ha-1) and RDF + water spray (2686 kg ha-1) but was at par with RDF + DAP 2% (3050 kg ha-1), RDF + MOP 0.5% (2992 kg ha-1) and RDF + Molybdenum 0.5% (2955 kg ha-1). The increase in seed yield with foliar application of 2% Urea along with RDF was 14.57% over control and 15.34% over RDF + water spray. Higher net returns (Rs. 49,006/- ha-1) and benefit: cost ratio (2.23:1) was obtained in treatment RDF + Urea 2% followed by RDF + DAP 2% foliar spray. Availability of N, P and K was significantly higher with treatment RDF + Urea 2% foliar spray over control and RDF + water spray. N and P uptake by soybean plants was significantly higher in treatment RDF + 2% Urea over RDF + water spray and RDF alone (control).</div>

<div>Influence of Foliar Application of Nutrient on Growth, Yield, Economics, Soil Nutritional Status and Nutrient Uptake of Soybean</div>

<div>Background: Cropping system approach has gained importance in agriculture and relative enterprises. In agriculture, management practices are usually formulated for individual crops. However, farmers are cultivating different crops in different seasons based on their adaptability to a particular season, domestic needs and profitability, therefore production technologies should be developed keeping in view&nbsp; of crops grown in a sequence in a year or more than one year depending on the crop duration. The current study aims in application of biofertilizers and inorganic fertilizers which are essential to raise the crop yield. Rhizobium has an enormous potential to fix atmospheric nitrogen. PSB solubilize the unavailable bound phosphates of the soil and make them available to plants which increase overall plant growth resulting in 10 to 15% increase in yield. 
 
Methods: A field experiment was conducted during rabi and summer seasons of 2017-18 and 2018-19 at College Farm, Navsari Agricultural University, Navsari. The treatment consisted of five treatment of integrated nutrient management to chickpea in rabi season as main plot treatments replicated four times in randomized block design. During summer season each main plot treatment was split into four sub plot treatments with different levels of RDF to fodder maize resulting in twenty treatment combinations replicated four times in split plot design.&nbsp; 
 
Result: Application of 100% RDF+Rhizobium+PSB (T3) to chickpea recorded significantly higher almost all the growth attributes, yield attributes and yield, nutrient uptake, protein content and yield as well as available nutrient status in soil being remained at par with 100% RDF (T1) and 75% RDF+Rhizobium+PSB (T4). while economics was remarkably improved due to inorganic fertilizers as well as combination of inorganic fertilizers with Rhizobium+PSB to chickpea and 100% RDF (S1) to summer fodder maize significantly highest all growth and yield attributes, available nutrient status of soil and economics.</div>

<div>Background: Farmers are facing the challenges to providing adequate availability of feed and fodders to livestock during dry period (lean period) which poses a major threat in livestock productivity. This study delineates, pelleting of feed and fodder helps to meet out the fodder requirement during lean period consequently improving the livestock productivity. 
 
Methods: The experiment was conducted at Forage Pelleting Unit, Department of Forage Crops in Agricultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu from March 2020 to June 2022 to identify the best suitable dry fodder crops for quality pellets production. The laboratory experiment was conducted and laid out in completely randomized block design with 11 treatments and three replications. The treatment consists of D1: Rice straw, D2: Maize stover, D3: Maize husk, D4: Sorghum straw, D5: Ragi straw, D6: Pearl millet stover, D7: Wheat straw, D8: Groundnut haulms, D9: Groundnut shells, D10: Sugarcane tops, D11: Blackgram husk were selected and produced into individual dry fodders pellets. Then, the selected dry fodders were harvested with the help of fodder harvester cum chaffer. The chaffed material was then dried using a solar drier at 70&deg;C for one day to attaining the ideal moisture of 12%. Then, dried materials were grinded by fodder pulverizer and then grinding material was conveyed through conditioning with passing the steam at 60 to 70&deg;C. Then, the conditioning material was passes through a pelletizer with 6 mm die diameter. 
 
Result: The observation on macro minerals (calcium, magnesium, potassium) and micro minerals (cobalt, zinc, manganese) were analyzed by using an Inductive Coupled Plasma Mass Emission Spectroscopy. The unpelleted and pelleted dry fodders showed a significant variation in the major and minor nutrients. In this regards, the calcium content recorded higher in groundnut haulms (D8) with 1.027 per cent and whereas ragi straw (D5) were recorded higher magnesium and potassium contents with 0.433 per cent and 2.178 per cent respectively. The minor nutrients like cobalt, manganese and zinc contents varied significantly due to pelleting process. From this study, rice straw (D1) recorded higher cobalt content with 0.378 per cent and whereas, ragi straw (D5) recorded higher zinc content (16.45 per cent) and while, manganese contents were registered higher in pearl millet straw (D6) with 54.88 per cent.</div>

<div>Background: The field experiment was conducted during 2018-19 experimental farm of Department of Agronomy, College of Agriculture, CSK HPKV, Palampur (H.P.), India. The experiment comprised of ten treatments (maize-wheat, maize-wheat + gobhi sarson, dhaincha-cabbage-frenchbean, sunhemp-vegetable pea-frenchbean, maize + soybean chickpea + linseed, rice-wheat + gram, hybrid sorghum + hybrid bajra-oats + sarson (hybrid), hybrid sorghum + hybrid bajra-ryegrass + berseem, babycorn-broccoli-frenchbean and okra-turnip-tomato) which was laid out in randomized block design with three replications. 
 
Methods: The present investigation was conducted during October 2018-October 2019 (Kharif and Rabi seasons) at an elevation of 1100 m amsl at a latitude of 32&deg;04&rsquo;N and longitude of 76&deg;35&rsquo; E at Bhadiarkar Experimental Farm, Department of Agronomy, CSK HPKV, Palampur, Kangra district of Himachal Pradesh, India. The soil of the experimental area falls in the order of Alfisols with Paleudalf as the great group as per the Udic Moisture Regime. During kharif and rabi season the crop varieties were applied with the recommended dose of N, P2O5 and K2O (kg ha-1). The source of nitrogen (N), phosphorus (P) and potassium (K) were urea, single super phosphate and muriate of potash. 
 
Result: In terms of food for human consumption, highest yield was obtained under the okra-turnip-tomato cropping sequence followed by dhaincha-cabbage-frenchbean and sunhemp-vegetable pea-frenchbean. While in terms of fodder yield, highest was obtained under hybrid sorghum + hybrid bajra-oats + sarson (hybrid) cropping sequence followed by hybrid sorghum + hybrid bajra-ryegrass + berseem. Highest maize grain equivalent yield was obtained with okra-turnip-tomato crop sequence. All other treatments remained superior in comparison to the maize-wheat crop sequence. Maize + soybean-chickpea + linseed emerged to be the best treatment with the highest benefit cost ratio. The treatment comprising okra-turnip-tomato sequence also proved to be the second-best treatment followed by hybrid sorghum + hybrid bajra-oats + sarson (hybrid). Sunhemp-vegetable pea-frenchbean recorded the highest uptake of the available nutrients from soil which was followed by babycorn-broccoli-frenchbean. There was net loss of available nutrients although the loss was less in the sequences with multiple crops during the year. The treatments had no significant effect on the pH and organic carbon content of the soil.</div>

​Effect of Different Crop Sequences on Soil Nutrient Status, Nutrient Uptake and Crop Yield in Western Himalayas of India

<div>Background:&nbsp;Weeds are the major biological constraint in okra due to its slow initial growth and wider row spacing. Due to severe crop weed competition, weeds removed considerable amount of nutrients from the soil. Competition exists between the crop and weed for nutrients results in nutrient deficiencies in crop. Hence the present experiment is formulated to assess the effect of stale seedbed, mulching and mechanical weeding on nutrient availability, nutrient uptake by crop and weed in okra. 
 
Methods: Experiment was conducted at Coconut Research Station, Balaramapuram, Thiruvananthapuram, Kerala during Rabi 2020-21. Design adopted for the study was RBD with two factors. The first factor was seedbed preparation (S) and the second factor was weed management (W). Stale seedbed (S1) and normal seedbed (S2) were the two different seedbed preparation methods and dried banana leaf mulch @10 t ha-1 alone (W1), dried banana leaf mulch @10 t ha-1 fb wheel hoe weeding at 30 and 45 DAS (W2), dried banana leaf mulch @10 t ha-1 fb hand weeding at 30 and 45 DAS (W3), wheel hoe weeding at 15, 30 and 45 DAS (W4), hand weeding at 15, 30 and 45 DAS (W5) and weedy check (W6) were the six different weed management options tried. Soil samples were collected after the harvest of the crop to determine the nutrient availability. Weed samples at 30 and 60 DAS and plant samples at harvest were analyzed to determine the NPK content and respective uptake of nutrients were calculated by multiplying the nutrient content with DMP. 
 
Result: Stale seedbed significantly enhanced the dry matter production and nutrient uptake by okra at harvest and lowered the nutrient removal by weeds at 30 and 60 DAS. Compared to non-stale, stale seedbed recorded significantly higher fruit yield. Among the weed management, wheel hoe weeding at 15, 30 and 45 DAS, recorded the lowest total weed dry weight at 30 and 60 DAS and resulted in the highest NPK uptake by crop and fruit yield. Uncontrolled weed growth resulted in a loss of 81.33, 18.16 and 50.84 kg N:P:K ha-1&nbsp;at 30 DAS and 102.09, 57.90 and 55.31 kg N:P:K ha-1 at 60 DAS, respectively. Nutrient removal by weeds was the lowest in wheel hoe weeding at 15, 30 and 45 DAS and the highest in weedy check. It could be concluded that, wheel hoe weeding at 15, 30 and 45 DAS was the best option for the management of weeds, higher nutrient availability and uptake and yield in okra.</div>
