ABSTRACT
A field experiment was conducted at Karaikal (Puducherry) during summer to study the performance of cotton (MCU 7) under drip fertigation in coastal deltaic region of Karaikal. The treatment consist of three different levels of soil moisture (I1- 0.4 and 0.6 ETc, I2- 0.5 and 0.7 ETc and I3- 0.6 and 0.8 ETc during before and after flowering stages, respectively) and four different doses of nutrients (N0- 0, N1- 50 %, N2- 75% and N3- 100 % RFD through fertigation) were taken up in combination along with farmers' practice as control. The results revealed that the irrigation levels I2 and I3 had produced higher number of bolls per plant and boll setting percentage leads to obtained higher yield while other yield parameters like number of sympodial branches, boll weight and all the quality characters were not significantly influenced by the irrigation levels. Among the nutrient levels N2 and N3 treatments had produced statistically similar with higher number of bolls per plant and produced higher yield.
