EFFECT OF VARIETY AND FERTILIZATIONON GROWTH AND YIELD OF SWEET PEPPER

Abstract

A field experiment was carried out at the research field of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur, during December 2021 to April 2022 to examine the effect of variety and fertilization on the growth and yield of sweet pepper. The experiment was laid out in two factorial randomized complete block design (RCBD) with three replications. Factor A included three (3) hybrid capsicum varieties i.e. V1- Green Bell, V2- Lalima and V3- Yolo Wonder and factor B comprised of five (5) fertilizations i.e. F1- 100% Recommended Dose of Fertilizer (RDF) + 10 t ha-1 Cowdung (CD), F2- 100% RDF + 10 t ha-1 PLBC, F3- 75% RDF + 2.5 t ha-1 PLBC, F4- 50% RDF + 5 t ha-1 PLBC and F5- 10 t ha-1 PLBC. Data on different parameters such as plant height, number of leaves plant-1, number of branches plant-1, SPAD value, fruit length, fruit diameter, single fruit weight, number of fruits plant-1, fruit yield plant-1, fruit yield plot-1, fruit yield hectare-1 were collected. Results revealed that V3 variety (Yolo Wonder) produced maximum values in most of the studied parameters followed by varieties V1 (Green Bell) and V2 (Lalima). In case of fertilizations, most of the parameters showed the highest values in F2 (100% RDF + 10 t ha-1 PLBC) followed by F1 (100% RDF + 10 t ha-1 CD) and the lowest values in F5 (10 t ha-1 PLBC). Interaction effect of variety and fertilization revealed that, V3F2 (Yolo Wonder with 100% RDF + 10 t ha-1 PLBC) showed the highest values and V2F5 (10 t ha-1 PLBC) gave the lowest values in most of the cases. The highest fruit yield (13.81 t ha-1) was found in V3F2 whereas the lowest fruit yield (10.18 t ha-1) was observed in V2F5.
