The Effect Of Organic Fertilizer And Urea On The Growth And Yield Of The Pea Plant Pisium Sativum L

Abstract

The study was conducted at the Agricultural Research Station of the College of Agriculture / Basra University in the 2018-2019 agricultural season with the aim of studying the effect of two levels of nitrogen fertilizer on the urea body at two levels (100, 50) kg/ d and three different types of organic fertilizers (sheep manure, cow manure and potassium humate fertilizer) at a level of 20 tons / ha in addition to the comparison treatment (without fertilization) in the growth and production of the local variety pea plant. The Plot- Split Design was carried out as a one-time split-factor experiment according to the RCBD with three replications for each treatment, so the number of experimental units was (2 × 4 × 3), so the number of experimental units would be 24 experimental units, and at each of the two adjacent lines, one sector. Urea fertilizer in the main plots to be the plot main factor, and organic fertilizer in the secondary plot as the plot sub. The study showed that the level of 100 kg / d of urea fertilizer caused a significant increase in plant height, leaf content of total chlorophyll and the percentage of nitrogen. The study also showed that the different types of organic fertilizers, at the level of 20 tons / ha led to a significant increase in plant height, total chlorophyll content, and the percentage of nitrogen, phosphorus and potassium in the leaves. As for the bilateral overlaps between the studied factors, they were significant for all traits.
