Effect of Promoting Diazotrophic Bacteria and Seaweed Extract Formula on Growth, Yield and Quality of Pea (Pisum Sativum L.) Plants

Two field experiments were carried out at the Experimental farm, Faculty of Agriculture, Alexandria University during 2017 and 2018 winter seasons. The aim of the current study was to investigate the effects of different bio-fertilizer types and seaweed extract formula ( 0, 5, 10 mll^-1 ) on vegetative growth characters, total pods yield and its components as well as chemical constituents of green seeds of the pea cultivar “Balmoral”. The results indicated that plant height, foliage fresh weight, foliage dry matter, number of branches plant-1, total yield (ton fed.^-1), N, protein and K contents in green seeds were significantly and positively affected by different bio-fertilizer types and the seaweed extract . The highest total pods yield fed.^-1 obtained by foliar application of seaweed extract at the rate of 10 mll^-1 in both growing seasons. Addition of bio-fertilizer (1) combined with foliar application of seaweed extract at the rate 10 mll^-1 gave the highest growth characters and total yield fed.^-1 with the highest protein content of green seeds of pea plants, in both growing seasons.
