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.
