Response of capsicum to boron and zinc application in terrace soils of Gazipur, Bangladesh

Abstract

A field experiment was conducted at vegetables research field of Horticulture Research Centre, Gazipur in terrace soils under Madhupur Tract (AEZ 28) during rabi seasons of 2009-10, 2010-11and 2011-12 to determine the optimum dose of boron and zinc for yield maximization of capsicum. There were sixteen treatment combinations comprising four levels each of B (0, 1, 2 and 3 kg ha^-1) and Zn (0, 2, 3 and 4 kg ha^-1) along with blanket dose of N₁₅₀P₆₅K₁₂₀S₂₀ kg ha^-1 including cow dung 10 t ha^-1 were used. The experiment was laid out in RCBD factorial with three replications. Results revealed that maximum mean number of fruits per plant (11.1), the highest fruit length (9.29 cm) and diameter (7.34 cm), maximum individual weight of fruits (122 g) were recorded from the combination treatment of B_2.0Zn_3.0 and the highest mean yield (31.8 t ha^-1) was also recorded from the same treatment. The 84.8% yield increase over control (B₀Zn₀) due to combined application of B_2.0Zn_3.0 kg ha^-1. The combined application of zinc and boron were observed superior to their single application. Therefore, the combination of B_2.0Zn_3.0 treatment may be considered as suitable dose for capsicum cultivation in terrace soils of Bangladesh.
