ABSTRACT
An experiment was conducted during kharif 2015 at water management research farm, Sher-e-kashmir University of Agricultural Sciences and Technology of Jammu (J&K), India to study the effect of irrigation scheduling on yield and nutrient uptake of different direct seeded basmati rice varieties. Results revealed that, irrigation schedules control (Normal transplanting with recommended water management practice) recorded significantly higher grain yield (3370 kg ha-1) and straw yield (6030 kg ha-1) which were statistically on par with irrigation at 2 days interval through sprinkler at 150% PE over the other treatments. Variety Pusa-1509 recorded significantly higher grain yield (3240 kg ha-1) which was comparable with Pusa-1121 (2960 kg ha-1). However, non-significant effect of varieties was observed on the straw yield. Irrigation schedules control recorded significantly higher uptake of nitrogen (61.09 kg ha-1), phosphorus (19.70 kg ha-1) and potassium (116.18 kg ha-1) and Pusa-1509 also recorded significantly higher uptake of nitrogen (51.87 kg ha-1), phosphorus (16.51 kg ha-1) and potassium (103.68 kg ha-1).
