Performance of high yielding drought tolerant varieties of maize and in situ moisture conservation techniques in Kandi region of Punjab, India
Journal Title: Journal of Applied and Natural Science - Year 2017, Vol 9, Issue 1
Abstract
In the present investigation, 87 front line demonstrations (FLDs) of maize were conducted on farmers’ fields to demonstrate the impact of high yielding drought tolerant varieties (JH 3459, Parkash and PMH 1) and in situ moisture conservation techniques (ridge sowing, sowing across the slope, summer ploughing and earthing up) on production and economic benefits in Kandi region of Punjab state during kharif seasons from 2011 to 2013 under rainfed situation. The improved production technologies recorded additional yield ranging from 29.7 to 47.6 q/ha with a mean yield of 37.1 q/ha and 24.4 to 42.6 q/ha with a mean yield of 32.7 q/ha for drought tolerant varieties and in situ moisture conservation techniques, respectively. The per cent average increase in yield of drought tolerant varieties over local cultivars was 35.8, while 15.6 for in situ moisture conservation techniques.The average extension gap, technology gap and technology index were 9.8& 4.4 q/ha, 3.7& 6.1q/ha and 9.1& 16.7 per cent, respectively in drought tolerant varieties and in situ moisture conservation techniques. FLDs recorded higher mean net returns i.e. Rs. 36,292 and 28,234 per ha. with B:C ratio of 2.53 and 2.17 for drought tolerant varieties and in situ moisture conservation techniques, respectively. The FLDS conducted revealed that availability of suitable high yielding variety and lack of knowledge about improved production technologies is the main bottleneck in maize production, enhancement of yield and knowledge of the farmers. Hence, the productivity of maize can be increased by adoption of the recommended management practices and the study resulted in convincing the farming community about potentialities of the recommended production technologies in yield enhancement.
