Effect of Some Safe Compounds on Growth and Productivity of Peas ( Pisum sativum L )

Abstract

Two field experiments were carried out during the two successive season of 2014/2015 and 2015 /2016 at Private Farm at El-Khelala vallage, Belqas Regon, Dakahlia Governorate, Egypt The experiment layout was completely randomized blocks design to investigate the effect of salicylic acid (SA) at 50 -100 -150 ppm and boron at 25 - 50 – 75 ppm each concentrate from salicylic acid and boron replicted twice the first foliar spray at 35 days from sowing and the second foliar spray at 35 and 45 day from sowing compared the control ( tap water)on pea (Pisum sativum L.) cv Master–B. The results showed that the vegetative growth parameters ( plant height, fresh and dry weights/plant, leaves number and leaf area / plant), Leaf chemical parameters ( total chlorophyll , caroteinods, N, P, K and boron ), pod yield and its components ( pod yield, pod weight, number of seeds per pod and weight of 100 fresh seeds) and pod chemical content( total carbohydrates, total sugar and protein )were affected significantly by foliar application treatments .The foliar treatment with salicylic acid 100ppm twice was most effective on vegetative parameters ( plant height, fresh and dry weights, leaves number and leaves area) followed by salicylic acid 150 ppm twice respectively. The highest values of pod chemical component were recorded with boron 75 ppm twice ( pod yield, pod weight, number of seeds per pod and weight of 100 seeds)in both seasons .The lowest values of the priveous parameters were recorded with the control ( non foliar application).
