Effect of magnetite, humic acid and biofertlizer as well as N, P and K levels application on growth and yield of pea (Pisum sativum L.) [electronic resource].

Two field experiments were carried out during winter seasons of 2010-2011 and 2011-2012, at the Experimental Farm of El Kassasein Horticultural Research Station, Ismailia Governorate, Egypt, to study the effect of NPK levels (25, 50 and 100 % of recommended dose), foliar applications (Control, HA. EM and HA+ EM) and magnetite levels (without and 150 kg/fed.) on growth, yield and its components of pea plants (Pisum sativum L.) cv. Master B 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 and leaves/plant and dry weight/plant ) and yield and its components (pod length, number of seeds/pod, weight of 100 seeds and green pods yield/fed). Spraying pea plants with a mixture of HA+ EM gave the highest values of vegetative growth parameters and yield and its components. In the same trends, treated plants with magnetite recorded the highest values of vegetative growth and yield and its components as compared to untreated plants.
