INFLUENCE OF CROP NUTRITION ON FRUIT, SEED YIELD AND QUALITY OF BRINJAL

Abstract

The experiment was carried out to investigate the influence of crop nutrition on seed yield and quality of brinjal at the farm of Sher-e-Bangla Agricultural University, Dhaka during period from October 2017 to March 2018. Two factor experiment included 4 macro nutrients treatments viz. F K 100 kg ha -1 ), F 2 (N 170 P 50 K 125 kg ha -1 0 (Control: N ) and F 3 (N 190 P 0 70 P 0 K K 150 0 kg ha kg ha ) and 3 micro nutrients treatments viz. N 0 (Control; Zn 0 , B 0 ), N 1 (Znso 4 ; 0.2%) and N (Borax; 0.2%) were delineated in Randomized Complete Block Design (RCBD) with three replications. Results showed that macro nutrients, micro nutrients treatments and their combination showed significant variation among the treatments on growth and yield parameters. In case of macronutrients, the highest fruit yield ha -1 (31.56 t), and seed weight ha -1 (1673.00 kg) were obtained from the treatment F 2 (N 170 P ) where the lowest results on respected parameters were found from control treatment F 0 (N 0 P 0 K 0 ). Regarding, micronutrient application the highest fruit yield ha (13.91 t) and seed weight ha -1 (1608.00 kg) were attained from the treatment N (Borax; 0.2%) where the lowest results on respected parameter were achieved from the control treatment of N 0 (Control, Zn 0 , B ). In terms of combined effect of macro and micro nutrients, the highest number of fruits plant 0 -1 (19.09), highest single fruit weight (60.58 g), highest fruit yield plant -1 (1157.00 g), highest fruit yield plot (13.88 kg), highest fruit yield ha -1 (3.18 g), seed weight plant (42.84 t), number of seeds fruit -1 (60.72 g), seed weight plot -1 -1 -1 2 50 ), F K -1 1 125 (N 150 kg ha -1 2 (711.40), seed weight fruit -1 (728.60 g) and seed weight ha -1 (2249.00 kg) were found from the treatment combination of F where the lowest results were obtained from the treatment combination of F 0 N . Regarding seed viability test, F 3 N 2 0 produced seed gave the highest seed vigor index (1013.6) where the lowest (425.8) was found from the seeds achieved from the treatment combination of F 0 N 0 . 2 N 2 P 30 -1 -1
