Growth and Marketable Green Pod Yield Performance of Pea ( Pisum sativum L.) under Varying Levels of NPK Fertilizers

摘要

An Experiment to assess the effect of different rates of nitrogen, phosphorus and potassium (NPK) on morphological traits of local pea variety was conducted at Vegetable Seed Farm ARI, Sariab, Quetta during the year 2000-2001. The fertilizer treatments comprised control, 25-0-0, 25-60-0, 25-0-60, 25-60-60, 50-0-0, 50-90-0, 50-0-90, 50-90-90, 75-0-0, 75-120-0, 75-0-120, and 75-120-120, Kg NPK/ 4m² in a Randomized Complete Block Design. The maximum plant height (46.30 cm), number of branches per plant (5.60), number of pods per plant (33.10), pod length (8.49 cm), seed per pod (6.00), pod yield per plant (188.43 gms), total marketable green pod yield per plot (6.02 kg) and per hectare yield (5.01 m.t), were recorded in treatment 75-120-120 or 75-120-0, Kg NPK ha ^-1, which displayed maximum green pod yield due to increase in pod per plant and pod length. It was further noted that an additional K did not increase the yield. Mean square attributable to treatment differed highly significant for all the quantitative traits showing the importance of fertilizer treatment in influencing morphological characteristics of pea plant.
