Abstract
Two field experiments were carried out during winter seasons of 2010 - 2011 and 2011-2012, at theExperimental 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.
 application of 50% NPK and spraying plants with humic acid + EM plus magnetite at 150 kg/fed recorded higher values of plant growth and green pod yield per feddan as compared to 100% NPK alone (control) without significant difference between both treatments. Fertilizing pea plants with 100% NPK and spraying plants with combination of humic acid + EM with application of  150 kg/fed magnetite gave the highest values of plant growth parameters, yield and its components as compared to other interaction treatments.
