Abstract

An experiment was conducted in the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, on garden pea, during the period of November, 2018 to January, 2019. The experiment was outlined in Randomized Complete Block Design (RCBD) with three replications. The experiment consisted of two factors; 3 levels of plant spacing. S₁ (30 cm × 10 cm), S₂ (30 cm × 20 cm) and S₃ (30 cm × 30 cm) and 4 levels of macronutrient management viz., T₀ (N₀P₀K₀S₀ kg ha^-1), T₁ (N₁₅P₂₅K₂₅S₅ kg ha^-1), T₂ (N₃₀P₅₀K₅₀S₁₀ kg ha^-1) and T₃ (N₄₅P₇₅K₇₅S₁₅ kg ha^-1). Results indicated that the highest seed yield (8.38 t ha^-1) and pod yield (10.56 t ha^-1) were found from S₁ (30 cm × 10 cm) compared to other plant spacing. Considering macronutrient application, the highest seed yield (7.57 t ha^-1) and pod yield (9.12 t ha^-1) were recorded from T₂ (N₃₀P₅₀K₅₀S₁₀ kg ha^-1), control treatment T₀ (N₀P₀K₀S₀ kg ha^-1) showed lowest. In terms of combined the highest seed yield (9.20 t ha^-1) and pod yield (11.82 t ha^-1) were achieved from S₁T₂, the lowest seed yield (4.64 t ha^-1) and pod yield (5.93 t ha^-1) were obtained from S₃T₀. In the combination of spacing and macronutrient dose, the highest Benefit Cost Ratio (BCR) (3.00) was recorded from the combination of S₁T₂ treatment and the lowest BCR (1.02) was obtained from S₃T₀ treatment and this combination can be recommended for farmers field evaluation.

Keywords: Benefit-cost ratio, garden pea, macronutrients, spacing & yield.
