Effect of Charcoal and Meniral Fertilizer Levels on Growth and Yield of Peas (Pisum sativum L.) under Sandy Soil Conditions

Abstract

Two field experiments were carried out during winter seasons of 2017 and 2018, at the Experimental Farm of El Kassasein Horticultural Research Station, Ismailia Governorate, Egypt, to study the effect of NPK levels (50, 75 and 100 % of recommended dose) and charcoal levels (without (control), 500, 1000 and 1500 kg/fed.) on growth, yield and its components and seed chemical constituents of pea cv. Master B grown under sandy soil conditions. Results indicated that increasing NPK fertilizer levels up to 100% recommended dose cause a significant increases in plant growth (plant height, number of branches/plant and number leaves/plant), yield and its components (pod length, number of seeds/pod, weight of 100 seeds and green pods yield/fed) and seed chemical constituents, i.e., N, P, K and protein percentage. Treated plants by using charcoal at 1500 kg / feddan gave the highest values of vegetative growth parameters, yield and its components and seed chemical constituents, i.e., N, P, K and protein percentage. Fertilizing pea plants with 100% NPK and application of 1500 kg/fed charcoal gave the highest values of plant growth parameters, yield and its componen and seed chemical constituents, i.e., N, P, K and protein percentage. Application of 75% NPK and Treated plants by using charcoal at 1500 kg / feddan gave higher values of plant growth and green pod yield per feddan as compared to 100% NPK alone (control) without significant difference between both treatments.
