dc.description.abstract | The present study was conducted at experimental farm of CSKHPKV, Palampur during the year 2020 with the objectives to evaluate the effect of subsurface drip irrigation and drip line layering on soil water dynamics, plant water content & water productivity, and to evaluate the effect of subsurface drip irrigation and drip line layering on nutrient uptake and crop productivity. The treatments comprised of two drip irrigation levels 0.4 PE (40 per cent of pan evaporation) and 0.8 PE (80 per cent of pan evaporation) with five subsurface layering viz., no layering, farm yard manure @ 10 t/ha, rice straw @ 10 t/ha, saw dust @ 10 t/ha, chopped weed biomass @ 10 t/ha. The tomato (Lycopersicum esculentum) crop was transplanted on May 4, 2020. The experimental results indicated that the soil water content and soil water stock was higher under 0.8 PE treatments which led to significantly higher plant height, relative leaf water content, marketable and straw yield as compared to 0.4 PE treatments. Among subsurface layering, plant height, marketable and straw yield, total NPK uptake were significantly higher under farm yard manure and lower under no layering. However, the root growth parameter was significantly higher under rice straw and lower under no layering. The gross return and B:C ratio were the highest under 0.8 PE + Farm yard manure and lowest under 0.4 PE + No layering treatment combination. The study concluded that the sub surface drip irrigation level of 0.8 PE and subsurface layering with Farm yard manure were the optimum treatment combination for obtaining maximum crop and water productivity | en_US |
