Effects of organic manure and chemical fertilizers on growth and yield of garden pea

Abstract

An experiment was conducted at Agronomy Farm of Bangladesh Agricultural University, Mymensingh (BAU) during rabi season of 2018−19 to see the response of garden pea to manure and fertilizers. The treatments were T₁: Control (no fertilizer or manure), T₂: Cowdung + Poultry manure + Mustard oilcake, T₃: Vermicompost + Poultry manure + Mustard oilcake, T₄: Urea + TSP + MoP + Gypsum and T₅: Cowdung + Urea + TSP + MoP + Gypsum. The experiment was designed in a factorial Randomized Complete Block Design (RCBD) with 4 replications. Urea, TSP, MoP and gypsum @ 45, 90, 40 and 50 kg ha⁻¹ were used as sources of nitrogen, phosphorous, potassium and sulphur, respectively. Cow dung, poultry manure, vermicompost and mustard oilcake were applied @ 30, 25, 2.5 and 0.025 t ha⁻¹, respectively. The results showed that the treatment T₅ significantly gave the highest values of vegetative growth and yield attributing characters’ i.e., plant height, number of branches per plant, number of pods per plant, pod length, pod breadth, number of seeds per pod, 100-seed weight, pod weight, pod yield and seed yield per hectare. The lowest values of growth and yield attributing characters were recorded with T₁. Sole chemical fertilizers (T₄) showed better performances than T₂ and T₃. Treatment T₅ gave higher result than T₄. So, for obtaining the highest growth and pod yield of pea (cv. BARI Motor3), treatment T₅ (Cowdung + Urea + TSP + MoP + Gypsum @ 30 t ha⁻¹, 45-90-40-50 kg ha⁻¹) could be the best combination.
