Bundelkhand region of Uttar Pradesh (UP), India is a major pulse producer in the Indian subcontinent. The agriculture production, particularly, pulses have been playing a great role in strengthening the economic conditions and are the source of livelihood of Bundelkhand region of Uttar Pradesh state. The productivity of chickpea crop is low due to lack of adoption of best management practices of chickpea by farmers Keeping these constraints under consideration the yield gap and technology gap assessed of the region by conducting Cluster Front Line Demonstrations on best management practices of chickpea during Rabi seasons in the year 2015-16 to 2018-2019, respectively. The demonstration was carried out in six villages of Mahoba district. The results revealed that the full technological gap in 5 practices (variety, seed treatment, seed inculcation with Rhizobium, weed management practices and plant protection), a partial gap in 3 practices (seed rate, fertilizer management and irrigation) and Nil gap in 2 practices (land preparation and sowing methods). Further, Average grain yield of chickpea showed a remarkable increase (32%) in CFLDs compared to Farmers practice (check). However, it is still behind to potential yield. The average technological gap, extension gap and technology index were 8.10 q ha-1, 3.30q ha-1 and 36.6% respectively. The study recommends the improvement of productivity of chickpea may be achieved through fulfilling the gap between demonstration yield and farmers practice yield. Therefore, more effort requires to determine the socio-economic factors for practicing age-old practice and extension efforts needed to the rapid diffusion of best management practices. Further, The future study on variable climate conditions and edaphic factors requires to determine the gap between potential and demonstration yield.
: The protein threonine phosphatases (PThPases) catalyze the reversible phosphorylation of threonine residues in proteins. They also regulate a large number of cellular processes including developmental and signaling pathways in eukaryotes.This study was conducted to determine the activity of PThPases as affected by different oxidizing agents in peanut (Arachis hypogaea L.) seedlings. In present work, the peanut seedlings were grown in dark on moistened whatman filter paper at 28±2 o C and it was observed that the activity of PThPase increased several folds in 6-8 days growing seedlings (without stressed). The eight days growing seedlings were then further treated with 2 per cent solution of different oxidizing agents (Hydrogen peroxide, Nitric acid, Potassium dichromate, Perchloric acid, Potassium permagnate, Magnese dioxide, Lead dioxide and Ammonium persulphate).It was observed that the specific activity of PThPase got an appreciable reduction by perchloric acid (HClO 4 ).After treating the 8 days growing seedlings with different % HClO 4 (0.5-5%), it was observed that 3% HClO 4 shows a pronounced effect on PThPase activity and the specific activity was reduced upto 65 per cent. In addition,when seedlings were treated with 3% HClO 4 for different time intervals (1-6h),4h treatment causes more than 88 per cent reduction in specific activity.The different parts of seedling (stressed with 3% HClO 4 for 4h) show the maximum reduction in specific activity in hypocotyl followed by epicotyl, cotyledon and then root. The results suggest that the role of PThPase is stress-related cellular processes and likely to inhibit the activity of intracellular protein threonine phosphatases.HOW TO CITE THIS ARTICLE : Sharma, Hari Om, Kumar, Pradeep and Chand, Mukesh (2017).
