Abstract

Attaining food security had been a major challenge for the nation since independence. Stagnant wheat production growth rates, depletion of grain stocks due to production shocks coupled with increasing demand for food has contributed to dwindling supplies.  As a result, physical, economic and ecological access to wheat still remains our major challenge. In this paper author try to highlight current problem in wheat cultivation and how to mitigate with some aspect, for betterment of wheat share in Indian economy. Further, an experiment was conducted at District Seed Farm (AB Block), Kalyani under Bidhan Chandra KrishiViswavidyalaya during winter season of 2014-16, with the objective to mitigate temperature problem (by manipulating sowing date i.e. 10^th November, 25^th November, 10^th December and 25^th December) with suitable cultivars (i.e. DBW 107, HD 2967, K0307 and DBW 39). , to combat the problem of late harvesting of rice.  Good yield and better B:C ratio observed with early sowing with cultivar of K0307 and HD 2967. Suitable crop cultivar with optimum time of sowing, mitigate some extent to alteration of climate problem. Various observations revealed that, barring Haryana, Punjab and Rajasthan, productivity in rest of the states were below the national level.  Expecting the impediments for wheat production in the coming years such as climate change, dynamics of pests and diseases, deteriorating soil nutrients, increasing cost of cultivation, global price volatility and changing consumption pattern, researchers have to put tremendous effort to sustain the existing growth trend by developing and sustaining the HYVs having tolerance to biotic and abiotic stresses with improved crop husbandry practices (irrigation, weed, nutrient management etc.). Potential improvements in wheat adaptation for climate change may include breeding new cultivars and changing agronomic practices. So, there is an urgent need to make detail probe on all these relevant issues through empirical research.  However, a major role has to be played  by the extension personnel  in disseminating those improved genotypes through  FLDs  at  farmers’  field  and  try  to bridge  the existing yield gaps to meet our mission on ensuring food and nutritional security  to all population.
