GROWTH AND YIELD OF TOMATILLO AS INFLUENCED BY PLANTING TIME AND MACRONUTRIENTS

Abstract

The experiment was carried out at the “Horticulture Farm” in Sher-e-Bangla Agricultural University, Dhaka during October 2019 to February 2020 to examine growth and yield of tomatillo as influenced by planting time and macronutrients. The experiment was set by taking two treatment factors. The treatment factors are: (A) Planting time (three times) viz. T 1 = 02 November, T II 2 = 12 November, and T = 22 November; and (B) Macronutrients (four levels) viz. F 0 = N 0 P 0 K = N Kg/ha. There were 12 treatment combinations such as T 200 P 60 K 100 Kg/ha, F 2 = N 250 P 90 K 120 1 F Kg/ha, F 0 , T 1 F 1 , T 3 = N 1 F 2 300 , T 1 P F 3 120 , T K 2 140 F 0 , T 2 F 1 , T , T 3 F 1 , T 3 F 2 , T 3 F . The two factors experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Seeds of SAU tomatillo-1 were collected from department of Genetics and plant breeding, SAU, Dhaka-1207. In case of planting time, the maximum number of fruits per plant (37.06), fruit weight (42.7 g), yield per plant ( 2.04 kg) and per hectare ( 85.06 t) were obtained from T 3 (22 November). In case of macronutrients, the maximum number of fruits per plant (47.26), fruit weight ( 48.47 g), yield per plant ( 2.75 kg) and per hectare ( 114.59 t) were obtained from F1 (N 200 P 60 K Kg/ha). Due to combined effect, the maximum number of fruits per plant (49.66), fruit weight ( 55.64 g), yield per plant ( 2.94 kg) and per hectare ( 122.84 t), vitamin C content (25.92 mg) were identified from T 100

(22 November with N 200 P 60 K Kg/ha ) treatment combination and minimum number of fruits per plant (14.0), fruit weight ( 24.69 g), yield per plant ( 0.5 kg) and per hectare ( 20.85 t), vitamin C content (16.63 mg) were noted from T 100 (02 November with N 0 P 0 K 0 Kg/ha) treatment combination. So, the T treatment combination appeared to be the best for achieving the higher growth and yield of tomatillo.
