EFFECT OF SOWING TECHNIQUES AND IRRIGATION MANAGEMENT PRACTICES ON YIELD, ROOT DEVELOPMENT, WATER USE EFFICIENCY AND ECONOMICS OF SUMMER GREENGRAM.

A field experiment was conducted on sandy loam soil during zaid (summer) seasons of 2006 and 2007 to find out the effect of different sowing techniques, irrigation schedules and irrigation depths on yield attributes, yield, water use efficiency, root development and economics of moong 'samrat'. The raised bed planting gave significantly higher seed and stick+straw yields as well as root development over flat bed planting during both the years of investigation. Higher gross return, net return and cost: benefit ratio were also recorded when raised bed planting method was adopted. Significantly highest average seed yield (15.28 q/ha) was observed under the irrigation schedule at 0.8 IW/CPE ratio which was higher to the tune of 1.18 (8.3%) and 3.99 q/ha (35.34% ) than that of 0.6 and 0.4 IW/CPE ratio, respectively. The highest stick + straw yield, total water use, root nodules/plant, fresh and dry weight of nodules/plant, gross return, net return and cost: benefit ratio were also obtained under irrigation schedule at 0.8 IW/CPE ratio. The irrigation depths were found to have non-significant effect on yield attributes, root development and yield. [ABSTRACT FROM AUTHOR]
