| Abstract | 262Field studies were conducted at Precision Farming Development Center farm of Tamil Nadu Agricultural University, Coimbatore to evaluate the crop water and fertigation requirements for grafted brinjal under drip irrigation system. The experiments were laid in strip-plot design with 27 treatments. The daily water requirement of grafted brinjal at different stages was found to be 1.9 L/day (initial stage), 3.6 L/day (vegetative stage), 4.2 L/day (flowering stage), and 5.2 L/day (harvesting stage).The total water requirement for the growth period under drip irrigation was 396.00 mm with mulch at 80% $ET_{0}$ level and 495.00 mm without mulch at 100% $ET_{0}$ level. It can be concluded that drip irrigation can save 16.17% of water with mulch as compared without mulch condition. The highest yield of 83.3 t $ha^{−1}$, highest water use efficiency of 62.87 kg $m^{−3}$, and fertilizer use efficiency of 416.5 kg $ha^{−1}$ kg of N, 555.3 kg $ha^{−1}$ kg of P, and 833.00 kg $ha^{−1}$ kg of K) were recorded in treatment under 25 p thickness plastic mulching at 80% $ET_{0}$ level and 100% RDF followed by $T_{6}$ (81.1 t $ha^{−1}$) and $T_{14}$ (79.2 t $ha^{−1}$) and lowest yield of 18.1 t $ha^{−1}$, least water use efficiency (19.38 kg $m^{−3}$), and fertilizer use efficiency (113.13 kg $ha^{−1}$ kg of N, 150.83 kg $ha^{−1}$ kg of P, and 226.25 kg $ha^{−1}$ kg of K) were found in control plot treatment with 60% $ET_{0}$ and 80% RDF. Increased fertilizer use efficiency with the decreased level of fertilizer dose through drip was observed. This chapter suggests that grafted eggplant crop responded well to drip irrigation with plastic mulch and fertigation levels. Grafting of eggplant cultivars on perennial and wild species increased the yield and availability period of the fruits, while standardization of cultural practices, irrigation, and nutritional requirements under different soils and climatic conditions helps in better crop stand. The use of grafting as an integrated pest management tool to manage biotic stress is most successful when complemented with sustainable farming system practices. Field studies were conducted at Precision Farming Development Center farm of Tamil Nadu Agricultural University, Coimbatore to evaluate the crop water and fertigation requirements for grafted brinjal under drip irrigation system. The statistical analysis indicated statistical significance for mulching, irrigation and fertilizer levels on the plant height and they are significant in their interaction. Fertigation offers the best solution for intensive and economical crop production where both water and fertilizers are delivered to crop through drip irrigation. |
