EFFECT OF SOIL MULCHING AND ORGANIC FERTILIZERS ON GROWTH AND YIELD OF LETTUCE (Lactuca sativa L.)

Abstract

The study was carried out in the vegetable field of the Department of Horticulture and Landscape Design / Faculty of Agriculture / Al-Qasim Green University in the agricultural season of 2016-2017 to study the effect of soil mulching treatments (no mulch, black plastic mulch, and transparent plastic), and two level of organic fertilizer palm residues (10 and 20 ton.ha-1) and chemical fertilizer (control) on vegetative, growth and yield of lettuce, and thus included the experiment was carried out in the field with split plots within RCBD, where the mulch treatments were distributed in the main plots and fertilizers treatments were distributed in sub-plots with three replicates. After the data were recorded and analyzed statistically according to the Duncan Mutable Rangiest with the probability level of 0.05 The result showed that soil mulching using the two types (black and transparent plastic) were superlour in plant length, leafe area, head diameter, the total head weight , the total and marketing of the heads yields compared to the treatments ,(covering with black plastic and without mulching) No significant effect was found between the added fertilizers in all the vegetative and yield traits mentioned above .
