EFFECT OF SULPHUR AND ZINC FERTILIZER ON THE GROWTH AND YIELD OF CHILI (BARI MORICH 4)

Abstract

The experiment was conducted at the research field of Sher-e-Bangla Agricultural University, Dhaka, during the Rabi season from November, 2021 to April, 2022 to investigate the effect of sulphur (S) and zinc (Zn) fertilizer on green chili production (cv. BARI Morich 4). The experiment consisted of two factors, viz., Factor A: 3 levels of Sulphur (S 0 : 0 kg ha -1 , S 1 : 20 kg ha -1 , S 2 : 30 kg ha ii -1 ) and Factor B: three levels of zinc (Zn 0 : 0 kg ha -1 , Zn 1 : 2 kg ha -1 and Zn 2 : 4 kg ha -1 ). Two factor experiments with Randomized Complete Block Design was followed with 9 treatment combination and replicated three times. Vegetative growth, yield contributing characters and yield were measured during the experiment. In case of S treatment, the tallest plant (66.12 cm), number of leaves plant -1 (96.13), number of branches plant -1 (15.50) were observed at 80 DAT and the highest number of fruits plant -1 (104.57), flowers plant (111.18), fruit length (7.10 cm), fruit diameter (0.56 cm), individual fruit weight (1.73 g), average fruit weight plant -1 (177.27 g), fruit yield ha -1 (28.21 t) were obtained from S 1 treatment. In case of Zn treatment, the tallest plant (66.06 cm), number of leaves plant (92.61), number of branches plant -1 (14.76) were observed at 80 DAT, the highest number of flowers plant -1 (109.24), fruits plant -1 (98.81), fruit length (6.93 cm), fruit diameter (0.58 cm), individual fruit weight (1.69 g), average fruit weight plant -1 -1 (169.05 g) and fruit yield ha -1 (27.35 t) were recorded from Zn 2 treatment. Considering combined effect of S and Zn, growth contributing parameter such as the tallest plant (74.83 cm), number of leaves plant -1 (101.32), maximum number of branches plant (16.74), highest number of flowers plant -1 (121.26), maximum number of fruits plant (114.09), highest fruit length (7.79 cm), highest fruit diameter (0.63 cm), highest individual fruit weight (1.78 g), average fruit weight plant -1 (203.49 g) and fruit yield ha (33.52 t) were recorded from S 1 Zn 2 . Meanwhile, the lowest values of the parameters were found in the control application of sulphur and zinc. Therefore, it can be concluded that 20 kg ha -1 of sulphur and 4 kg ha -1 of zinc were found beneficial for growth and yield of green chili.
