EFFECTS OF ORGANIC AND INORGANIC FERTILIZERS ON GROWTH, YIELD AND NUTRIENTS CONTENT OF CAPSICUM (Capsicum annuum L.)

Abstract

An experiment was carried out at Sher-e-Bangla Agricultural University (SAU), Sher-eBangla

Nagar, Dhaka-1207 to study the effects of organic and inorganic fertilizers on growth, yield, and nutrients content of capsicum (Capsicum annuum L.) during the period from November 2021 to March 2022. The experiment considered 8 treatments viz. T 0 (control), T 1 (Recommended doses; RD of inorganic fertilizer), T 2 (Vermicompost - 3.5 t ha -1 ), T 3 (Poultry manure - 8 t ha -1 ), T 4 (50% vermicompost + 50% inorganic fertilizer of RD), T 5 (25% vermicompost + 75% inorganic fertilizer of RD), T 6 (50% poultry manure + 50% inorganic fertilizer of RD) and T 7 (25% poultry manure + 75% inorganic fertilizer of RD). The treatment T 5 (25% vermicompost + 75% inorganic fertilizer of RD) exhibited the highest plant height (51.93 cm) but the treatment T 4 (50% vermicompost + 50% inorganic fertilizer of RD) showed the highest number of leaves plant (9.47), flowers plant -1 (11.53), fruits plant -1 -1 (52.07 cm), branches plant (8.71), fruit length (89.93 mm), fruit diameter ( 67.27 mm), individual fruit weight (94.85 g), number of fruits plot -1 (40.67), yield plot

(3859.00 g) and yield (19.30 t ha -1 ) whereas control treatment showed least performance. Regarding the nutrient content of capsicum, N content differed significantly and the treatment T 7 (25% poultry manure + 75% inorganic fertilizer of RD) showed the maximum N content (1.73%) whereas T 0 (control) treatment showed the lowest result (0.57%). P and K contents of fruit showed non-significant variation among the treatments. So, it can be concluded that the treatment T 4 (50% vermicompost + 50% inorganic fertilizer of RD) treatment was very much promising for higher capsicum production (ASTHA F1) followed by T 5 (25% vermicompost + 75% inorganic fertilizer of RD). Treatment of 50% vermicompost + 50% inorganic fertilizer of RD (T 4 ) can be recommended at farmers level to achieve higher capsicum production.
