GROWTH, SEED YIELD AND QUALITY OF CHILLI AS INFLUENCED BY FERTILIZER MANAGEMENT AND SPACING

Abstract

An experiment was conducted at the central farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period from October 2018 to April 2019 to determine the growth, seed yield and quality of chilli as influenced by fertilizer management and spacing. The experiment consisted of two factors Factor A: Different fertilizer management such as F : Vermicompost (15 t ha -1 ), F 2 : 110 kg ha -1 N, 170 kg ha -1 0 , 100 kg ha : ½ Vermicompost + ½ N 110 P 170 K 100 kg ha -1 ; Factor B: Different types of plant spacing such as S 1 : 60 cm × 30 cm, S 2 : 60 cm × 45 cm and S : 60 cm × 60 cm. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on different growth and yield contributing characters were recorded. Results indicated that fertilizer management and spacing had a significant influence on most of the growth, seed yield and quality components of chilli. Under this investigation, it was revealed that plant height, number of branches per plant, number of leaves per plant, fruit length, the weight of dry fruits, number of dry fruits per plant, yield per plant dry fruits, number of seeds per fruit, thousand seed weight, germination percentage, root length, shoot length and seedling length were found to be maximum from F 3 S 3 treatment combination and minimum from F 0 S 1 3 : Control, F -1 K and F treatment combination

Yield of dry fruits (3.06 t) and seed (353.35 kg) per hectare were found to be maximum from F 3 S 2. By contrast minimum dry fruits (0.92 t) and seed yield (143.68 kg) were given from F 0 S

3 and F 0 S Considering the yield of dry fruits and seed per hectare, F3 (½ Vermicompost + ½ N 1. 110 P 170 K ) along with S 2 100 (60 cm × 45 cm) could be the best production package for the production of chilli.
