Impact of Foliar Boron and Fertilizer Management Systems on Growth, Yield and Quality of Brinjal

A field experiment was conducted during the rainy season of 2017–18 at Horticulture Farm, S.K.N. Agriculture University, Jobner, Jaipur, Rajasthan to study the role of foliar spray of boron on the growth, yield, and quality of Brinjal (Solanum melongena L.) The study was laid with 18 treatments (TThree replicates of six treatments) viz., INM levels (control, 100% inorganic NPK, 75% inorganic NPK +25%VC (vermicompost), 50% inorganic NPK +50%VC, 25% inorganic NPK +75% VC, and 100%VC and boron levels (control, 100 ppm, and 200 ppm). It was observed that there was a significant (P < 0.05) increase in the plant height and plant spread at 30, 60, and 90 DAT on the application of 75% inorganic NPK +25%VC on the brinjal crop, while the application of inorganic 50% NPK +50%VC significantly (P < 0.05) increased chlorophyll content (mg.g-1), fruit length (cm), fruit weight (g), fruit yield ha-1 (q), Nitrogen and Phosphorus content in fruit (%), as compared to control but statistically at par with 25% inorganic NPK +75%VC. The application of boron (200ppm) significantly (P < 0.05) increased the plant height and plant spread at 30, 60, and 90 DAT(cm), chlorophyll content (mg/g), fruit length (cm), fruit weight (g), fruit yield hectare-1(q), NP content in fruit (%), as compared to control and boron (100 ppm).
