Abstract: During the kharif-summer of 2019 to 2021, an experiment was undertaken at College farm, PJTSAU, Hyderabad, to investigate the influence of drip irrigation and fertigation levels on productivity, profitability, and economics of a high-density cotton sweetcorn production system. The experiment included twelve treatments with three irrigation and four fertigation levels, all replicated three times in a Factorial randomized block design (FRBD). Compared to 0.6 and 0.8 Epan, irrigation at 1.0 Epan produced considerably higher system gross returns, system net returns, system B:C ratio, system profitability, and system productivity. Among the fertigation levels, application of 125 percent RDNK in differential dosage as per crop coefficient curve resulted in higher system gross returns, system net returns, system B:C ratio, system profitability, and system productivity, all of which were comparable to application of 125 percent RDNK in differential dosage as per recommendation.
