The present study was conducted within gravity flow Ranbir canal system of Jammu. The spatial and non-spatial data inputs were used for determining water productivity of wheat crop dur- ing rabi season. The study indicated that minimum water requirement during three stages of wheat crop growth i.e. CRI, maximum-tillering and boot- ing stage at system level are not met by canal water, as it remains closed during the period. Comparison of normalized vegtative index (NDVI) for wheat crop (Raj-3077) within problematic reach of iden- tified canal system i.e. from middle to tail reach during rabi of 2012-13 was in the range of 0.2 to 0.5 as rainfall was 48.4% higher than the proceding year rabi of 2011-12 during which NDVI was in the range of 0.0 to 0.1 only. The average yield of wheat in the farmer’s fields was found in the range of 25 q/ha having yield potential of 35-40 q/ha. Under these circumstances, Scalability of proven water management techniques like laser leveling, furrow irrigated raised bed (FIRBS) and boarder strip irrigation for wheat crop is essential including in- stallation of shallow tube-wells within farmer fields . These interventions shall improve water productiv- ity of wheat from 0.83 to 1.16 kg/m in near future within middle to tail reach of farmer’s fields of the study area. Not Available |
