A field experiment was conducted for three consecutive rabi seasons (2011-12 to 2013-14) to evaluate the effect of irrigation depth (0.4, 0.6, 0.8 and 1.0 CPE) and NK fertigation (50 and 100% of adjusted recommended dose) along with a control (basal application of soil test based adjusted recommended NPK fertilizer and surface irrigation of 5 cm) on the productivity of garden pea at Palampur. Result revealed that irrigation and fertigation with micro-sprinkler led to 60.9% less use of water and 10.0% higher green pod yield. Consequently, water use efficiency was increased by 3.12 times over the recommended practices. Every fifth day irrigation with 80% CPE (CPE 0.8) resulted in significantly higher green pod yield than every fifth day irrigation with either 60% CPE (13.74%) or 40% CPE (19.96%). Irrigation with minimum depth of water (0.4 CPE) resulted in maximum water use efficiency of 6.51 kg green pods m-3 of irrigation water used for crop production. Fertigation of sprinkler irrigated crop either with 50 or 100% of recommended soil-test based NK had no effect on green pod yield, gross return and water use efficiency.Keywords

A field experiment was conducted for three consecutive summers (2013-15) to evaluate the effect of three drip irrigation intervals viz. one (Every alternate day irrigation), two (Every third day irrigation) and three days(Every 4th day irrigation) and three fertigation frequencies viz. once a week (Every 7th day with entire fertilizer dose in 13 equal splits), twice a week (Every 3th day fertigation with entire dose in 20 equal splits) and twice a month (Every 15th day with entire dose in 6 equal splits) along with a control arranged in factorial randomized block design with three replications. Results revealed that crop grown with 75 per cent of recommended NPK fertigation under gravity fed drip irrigation gave comparable brinjal yield and gross returns to crop grown with recommended package of practices i.e. fertilization with recommended NPK and surface irrigation of 5 cm at 7 day interval. B: C ratio was significantly lower in former case mainly due to higher cost of soluble fertilizers. Increase in irrigation interval did not have any significant effect on brinjal yield, gross returns, net returns and B: C ratio. Irrigation interval of two days resulted in significantly higher WUE than irrigation interval of either one day (8.68 %) or three day (4.28 %).Fertigation frequency of twice a month resulted in significantly higher brinjal yield (16.86 %) and water use efficiency (19.28 %) than fertigation frequencies of once a week and twice a week, respectively.Keywords

A field experiment was conducted for three successive years from 2006 to 2009 to assess the effect of tillage (conventional, conservation and zero tillage) and nitrogen management (recommended, 125 % of recommended and 150 % of recommended nitrogen) on late sown wheat due to introduction of short season radish crop in between two crops of maizewheat cropping system. Conservation tillage used 10.2 % less water than conventional and zero tillage and increased WUE by 35.8 per cent. It also resulted in significantly higher grain yield compared to conventional and zero tillage (about 13 and 22 %). The application of 125 % of recommended nitrogen increased water use efficiency by 17 % than recommended nitrogen. Further increase to 150 % of recommended nitrogen increased WUE by 6 %.The application of 150 % of recommended nitrogen resulted in significantly higher grain yield (17 %) than recommended nitrogen.Keywords
