ABSTRACT

A field experiment was carried for three kharif and two intervening rabi seasons, beginning with kharif 2006 at WMRC research farm of SKUAST Jammu on clay loam soil, to analyze the influence of puddling intensities and organic amendments on water productivity of rice basmati and its residual effect on following wheat. Water productivity of basmati rice achieved as a consequence of incident rainfall and applied differential irrigation in C1,C2 with 7cm depth of irrigations at 8-day frequency) and S1, S2 (System of Rice Intensification) with 5cm irrigation at 8 day frequency or less) monitored at 3 week intervals throughout rice growth seasons of kharif 2006 and 2007 revealed that water productivity was significantly higher in conventionally transplanted plots without organic amendments (C1) than the other treatments (C2,S1,S2), all receiving organic sources of nutrients during the first season. But in the next two Kharif seasons, SRI plots and conventionally transplanted plots had simlar water productivity. There was neither any residual influence of puddling intensities, nor of methods of rice establishment nor of organic additions to soil during rice crop on the grain yield of succeeding wheat crop.
