Background: Front line demonstration in chickpea is to demonstrate and popularize the improved agro-technology on farmers&rsquo; fields of Koppal District under varied existing farming situations for effective transfer of generated technology and fill the gap between improved technology and adopted/indigenous technology to enhance the productivity. The average productivity of chickpea is low due to lack of improved agrotechnology, mostly grown under rainfed conditions and vulnerable attack of pests and diseases causing huge production losses. Therefore, in order to conduct/create awareness of front-line demonstration with improved agrotechnology&rsquo;s for higher productivity and profitability in rabi chickpea.&nbsp; 
 
Methods: ICAR-Krishi Vigyan Kendra, Koppal (Karnataka) was conducted frontline demonstrations (FLD) for two consecutive years during Rabi seasons of 2021-22 and 2022-23 at farmer&rsquo;s fields of Koppal district of Karnataka state. The data on productivity, yield gap analysis, per cent disease index and economics in demonstrated plots (DP) were compared with existing farmer&rsquo;s practice (FP).&nbsp; 
 
Result: Two-year results concluded that 19.13 per cent yield increment was observed in the demonstration plot as compared to existing farmers practices. Use of improved methods of chickpea cultivation can reduce the technology gap to a considerable extent thus leading to increased productivity and profitability of farmers in the Koppal district under Northern Dry Zone of Karnataka.

<div>Background: Continuous rice cultivation has a negative effect on sustainable rice production. Crop rotation can increase the yield and soil quality. This study aimed to provide information on the morpho-physiological fingerprints of rice cultivars in different crop rotation systems. 
 
Methods: Twelve rice cultivars were evaluated in terms of their morpho-physiological in three crop rotation systems, i.e., rice-rice-rice, maize-maize-rice (M-M-R) and vegetable-vegetable-rice, at the Agrotechnology Innovation Center, Universitas Gadjah Mada at Berbah District, Sleman Regency, Special Province of Yogyakarta, Indonesia, from December 2020 to June 2021. 
 
Result: The results revealed an interaction between rice cultivars and the crop rotation system, with the effects observed on the nitrogen, phosphorus and potassium contents in the leaf tissue (NC, PC and KC, respectively), crop growth rate, total dry weight per clump, empty grain per clump (EG) and grain weight per clump (GWC). The increase in NC, PC and KC positively affected the increase in GWC. The GM 8 cultivar in the M-M-R crop rotation system showed lowest EG of 3% and highest GWC of 133.90 g clump-1.</div>
