Growth parameters of different mustard (Brassica campestris L) varieties as effected by different levels of fertilizers

Abstract

This field experiment was conducted to find out the effect of the different levels of fertilizers on the growth parameters of mustard varieties of BARI sharisa-9 (V₁), BARI sharisa-12 (V₂) and BARI sharisa-15 (V₃), and to find out the optimum and economically viable fertilizer dose. A total of 5 treatments, including one control comprising of a different package of chemical fertilizers, were used in this study. The treatments were F₁ (N₁₂₀+P₃₅+K₅₀+S₂₅+Zn₄+B₂), F₂ (N₉₀+P₃₀+K₄₀+S₂₀+Zn₃+B_1.5), F₃ (N₆₀+P₂₅+K₃₀+S₁₅+Zn₂+B₁), F₄ (N₃₀+P₂₀+K₂₀+S₁₀+Zn₁+B_0.05) and F₅ (Native nutrient). The data revealed that leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR), net assimilation rate (NAR) and plant dry matter accumulation were affected by different fertilizer applications. The present result revealed that N₁₂₀, P₃₅, K₅₀ , S₂₅, Zn₄ and B₂ kg/ha would be the most suitable fertilizer doses for production of the mustard variety BARI sharisa-9.
