EFFECT OF ORGANIC FERTILIZER SOURCRS AND CHEMICL FERTILIZATION ON SOME SOIL PHYSICL TRAITS AND YIELD OF SUMMER SQUASH (Cucurbta Pepo L.)

Abstract

The results showed that the organic fertilizer mixture (1:1) 30 tons/ha with chemical fertilization recorded the lowest level of bulk density of 1.2 g/cm3, the organic fertilizer mixture (1:1) 30 tons/ha with chemical fertilization recorded the highest percentage of aggregation stability amounting to 16.17%, the organic fertilizer palm fronds recorded the highest level of ready water with an average of 5.50 cm3/cm3 and the organic fertilizer mixture (1:1) 30 tons/ha without chemical fertilization recorded the highest level of ready water as it reached 6.93%, the organic fertilizer mixture (1:1) 30 tons/ha with chemical fertilization gave the largest production amount, which amounted to 26.67 tons/ha Keywords: Organic fertilizer, physical properties of the soil, squash.
