Effect of organic and chemical fertilizers on growth and yield of garden pea

A field experiment was carried out at the Crop Botany Field Laboratory of Bangladesh Agricultural University, Bangladesh. It was done during rabi season of 2017−18 to study the effect of organic and chemical fertilizers on growth and yield of garden pea (BARI Motor-3). The experiment was laid out in Randomized Complete Block Design (RCBD) with five treatments and four replications. The treatments were T1: Control (no fertilizer), T2: Cowdung + Poultry Manure + Mustard oilcake, T3: Vermicompost + Poultry Manure + Mustard oilcake, T4: Urea + TSP + MoP + Gypsum and T5: Cowdung + Urea + TSP + MoP + Gypsum. Urea, TSP, MoP and gypsum were used as a source of nitrogen, phosphorous, potassium and sulphur @ 45, 90, 40 and 50 kg per ha, respectively. Cowdung, poultry manure, vermicompost and mustard oilcake were also applied as the organic treatments @30, 25, 2.5 and 0.025 ton per ha, respectively. Amongst the organic and chemical fertilizers, combined application of T5 significantly showed 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 seeds weight, pod weight, pod yield and seed yield per hectare. The lowest values of growth and yield attributing characters were recorded from T1. When only chemical fertilizers (T4) were used for plants, they gave higher performance than T2 and T3. Moreover, T5 gave higher result than T4. So, for obtaining the highest growth and yield of pea, T5 is the best combination.
