Effect on yield attributes
The result stipulated that differences in number of pods plant
-1 of chickpea were found significant which was furnished in Table 3. Statistically, maximum number of 118.7 pods plant
-1 was recorded in the treatment supplemented with the dose of 1/3 dose of Farmyard manure+1/3 dose of Vermi-compost+1/3 dose of Poultry manure(T
7) as which was comparable with 50% dose of Farmyard manure+ 50% dose of Poultry manure(105.3 Nos.) (T
5) and (T
1) 100% through farmyard manure (101.1 Nos.). While minimum number of pods plant
-1 (62.8 Nos.) were obtained in T2 (100% through Vermi-compost) as presented in Table 2.
The result depicted that yield per plant of chickpea was found significant, presented in Table 2. Among all tested formulation of organic sources, significantly, highest yield (36.9 g) per plant of chickpea was recorded in T7(1/3 dose of Farmyard manure+1/3 dose of Vermi-compost+1/3 dose of Poultry manure) as compared to control treatment which was on par with the 100 % through farmyard manure (T
1) (29.9 g) and 50% dose of Farmyard manure+50% dose of Poultry manure (T5) (29.9 g).The minimum yield per plant
-1 (17.4g) were resulted in T8 (1/3 dose of Farmyard manure+1/3 dose of Vermi-compost+1/3 dose of Poultry manure) + Phosphate Solubilizing Bacteria (Table 2).
In general, the data showed that the maximum no. of pods per plant and yield per plant recorded relatively higher in T7 (1/3 dose of Farmyard manure+1/3 dose of Vermi-compost + 1/3 dose of Poultry manure) than the other treatments. It was may be due to application of a good nutrients through formulation of organic sources to the soil as (1/3 dose of Farmyard manure+1/3 dose of Vermi-compost+1/3 dose of Poultry manure) by which soil remained rich in organic carbon (matter) and improve soil porosity and give the favorable environment to the microbial activities and better nodulation. This rise in yield attributes could be attributed to improved photosynthate translocation towards the sink, resulting in higher grain yield. Similar findings were reported by
Jat and Ahlawat (2004);
Patel and Thanki (2020).
The data based on the parameter weight of pods plant
-1 was depicted and Table 2 were found significant. Among all, treatments significantly highest weight of pods plant
-1 (42.8 g)was recorded in T7 (1/3 dose of Farmyard manure+1/3 dose of Vermi-compost+1/3 dose of Poultry manure), which was closely followed by T1(100% through farmyard manure) and T5 (50% dose of farmyard manure+ 50% dose of Poultry manure). While minimum weight of pods plant
-1 (22.8 g) were recorded in T8 (1/3 dose of Farmyard manure+1/3 dose of Vermi-compost+1/3 dose of poultry manure+Phosphate Solubilizing Bacteria.
The result revealed that maximum weight of pods per plant was recorded under formulation of organic sources with (1/3 dose of Farmyard manure+1/3 dose of vermicompost +1/3 dose of Poultry manure), may be due to application of organic manures which could improve soil nutrient status, soil structure and soil porosity which helps to proliferate maximum number of branches per plant and obtain maximum number of pods. These findings were similar to the results of, Pandey
et al. (2006).
The data pertained to no. of seeds pods
-1 were found non- significant. Among all tested formulation of organic sources, non-significantly highest No. of seeds pods-1 of chickpea was recorded in T
7 (1/3 dose of Farmyard manure+1/3 dose of Vermi-compost+1/3 dose of Poultry manure) as compared to other treatment formulations, while minimum No. of seeds pods
-1 were recorded in T6 (50% dose of Vermi-compost+50% dose of Poultry manure).
The result indicated that 100-seed weight (seed index) was found non-significant, as presented in Table 3. Among all tested formulation of organic sources, non-significantly maximum100-seed weight (seed index); (28.2) of chickpea was recorded in T3 (100% through Poultry manure) as compared to other treatment formulations, which was closely followed by T
7 (26.8) and T6 (26.2) respectively. While minimum No. of seeds pods
-1 (24.1) were recorded in T
4 with (50% dose of farmyard manure +50% dose of Vermi-compost).
Effect on yield
The data based on the parameter grain yield, straw yield and biomass (q/ha.) as presented in (Table 3) were found non-significant. Among all tested formulation of organic sources, highest grain yield (31.3 q/ha.) of chickpea was recorded in T
7 with the application of (1/3 dose of Farmyard manure+1/3 dose of Vermi-compost+1/3 dose of Poultry manure) as compared to other treatment formulations, which was closely followed by T
1 (28.1 q/ha.) and T4 (27.9 q/ha.) respectively, while minimum grain yield (22.9 q/ha.) was recorded in treatment T
6.
Non-significantly highest straw yield (57.3 q/ha.) of chickpea was recorded in T
5 with the application of (50% dose of farmyard manure+ 50% dose of Poultry manure) as compared to other treatment formulations, which was closely followed by T
3(51.5 q/ha.) and T
7(46.9 q/ha.) respectively, while minimum straw yield (39.5 q/ha.) was recorded in treatment T
8.
It is clear from (Table 3) that biomass yield of chickpea was non-significantly affected by the combination of organic sources applied on chickpea in T
5 enriched with(50% dose of Farmyard manure+ 50% dose of Poultry manure) could result in maximum quantum of biomass yield (84.5q/ha) as compared to other treatment combinations, which was closely followed by T
3 (79.6 q/ha.) and T
7 (78.2 q/ha.) respectively, while minimum biomass yield (64.9 q/ha.) was recorded in treatment T6/T8.
On the basis of present finding, the concept of eco-friendly integrated nutrient management is sincerely endorsed particularly in organic cultivation of chickpea because grower would like to eat/use toxin free and healthy agriculture produce. It is therefore, minimal residue containing seed would be very safe and noteworthy for consumer and also for growers to get high remuneration. The grain, straw and biomass yield were influenced non-significantly with thesupply of organic source of nutrients. These findings were similar to the results of
Asewar, 2003;
Siag and Yadav, 2004;
Jat and Ahlawat, 2006;
Muddukumar, 2007;
Chauhan et al., 2010 and
Kanwar and Paliyal, 2002.
Economics
It is perceptible from data that the maximum net return in chickpea (116671 ha
-1) were obtained in T
7 enriched with (1/3 dose of Farmyard manure + 1/3 dose of vermi-compost +1/3 dose of Poultry manure) which was closely followed by T
1 and T
4 respectively and benefit: cost ratio was found maximum in T
1 enriched with (100% through Farmyard manure) which was closely followed by T
0 and T
7 respectively, presented in (Table 4).
Among the treatments, the gross return was highest under combination of (1/3 dose of farmyard manure + 1/3 dose of vermi-compost + 1/3 dose of poultry manure) followed by (100% through FYM), (100% through poultry manure) respectively. The Net return was highest with when nutrient applied in combination of organic manures (1/3 dose of farmyard manure + 1/3 dose of Vermi-compost + 1/3 dose of Poultry manure) followed by (100% through FYM). It was due to obtained maximum grain and straw yield and less cost of cultivation than rest of the treatments. The application of 100% vermi-compost recorded the higher cost of cultivation than the rest of treatments while the maximum benefit: cost ratio was observed under application of 100% through FYM. It was due to less cost of cultivation than the combination of (1/3 dose of Farmyard manure + 1/3 dose of Vermi-compost + 1/3 dose of Poultry manure) while lowest cost of cultivation was observed under control treatment. These findings were similar to the results of
Pandey et al. (2006).
