The Effect Of Organic And Chemical Fertilizers On Growth, Yield And Quality Of Garden Pea

This experiment was conducted at Farm of Agronomy. Department of Agronomy, Bangladesh Agricultural University, Mymensingh, during growing rabi season of 2018−19 to investigate the effect of five application of fertilizers at rate: T1: Control (no fertilizer), T2: Cow dung + Poultry Manure + Mustard oilcake, T3: Vermi compost + Poultry Manure + Mustard oilcake, T4: Urea + TSP + MoP + Gypsum and T5: Cow dung + Urea + TSP + MoP + Gypsum. The experiment involved 5 treatments arranged a factorial experiment in split plots system within a Randomized Complete Block Design (RCBD) with 4 replication. Urea, TSP, MoP and gypsum were used as a source of nitrogen, phosphorous, potassium and sulphur @ 45, 90, 40 and 50 kg ha−1, respectively. Cow dung, poultry manure, vermin compost and mustard oilcake were also applied as the organic treatments @ 30, 25, 2.5 and 0.025 ton ha−1, respectively. The results could be summarized as following: The combined application of T5 showed significantly 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.
