- Intervention effect Wider interplant spacing increased height, green cob weight, kernels per cob, kernel weight, and kernel recovery.
- Intervention effect Cob yield was greatest at 60 cm 20 cm spacing and exceeded yield at 60 cm 25 cm.
- Intervention effect Reducing spacing from 60 cm 20 cm to 60 cm 15 cm reduced cob yield by 33.2%.
- Intervention effect At 60 cm 20 cm spacing, kernel yield, productivity, profitability, returns, nitrogen uptake, and nitrogen use efficiency were higher.
- Intervention effect Nitrogen rates up to 120 kg/ha improved height, dry weight, cobs per hectare, kernels per cob, kernel weight, cob weight, kernel recovery, yield, and return.
- Intervention effect Increasing nitrogen reduced cob bareness.
- Intervention effect Nitrogen uptake and available and residual soil nitrogen peaked at 150 kg N/ha.
- Intervention effect Increasing nitrogen reduced agronomic and physiological nitrogen use efficiency.
- Observation The economic optimum was 125.7 kg N/ha with 14.21 t/ha green cob yield and 7.55 t/ha response.
- Observation Response to the optimum nitrogen level was 60.09 kg green cob per kg N applied.
- Recommendation The authors recommend 60 cm 20 cm spacing with 120 kg/ha nitrogen for maximum cob yield and net profit in Kashmir valley.
