Effect of coconut husk organic fertilizer from liquid organic fertilizer waste on growth and yield eggplant (Solanum melongena L.)

Abstract

The objective of the study was to determine the effect of using coconut husk organic fertilizer from liquid organic fertilizer waste on the growth and yield of eggplant. The factors of the experiment were; P0 = 0 tons ha-1coconut husk organic fertilizer from liquid organic fertilizer waste, P1 = 7 tons ha-1coconut husk organic fertilizer from liquid organic fertilizer waste, P2 = 14 tons ha-1 coconut husk organic fertilizer from liquid organic fertilizer waste, P3 = 21 tons ha-1coconut husk organic fertilizer from liquid organic fertilizer waste arrange as a randomized block design factorial. The results show that the doses of coconut husk organic fertilizer from liquid organic fertilizer waste 21 tons ha-1 gives a higher fruit weight of 69.97 tons ha-1. The lowest result is without the provision of coconut husk organic fertilizer from liquid organic fertilizer waste with a weight of 52.87 tons ha-1. In addition, there is a significant relationship between the rate of plant growth and the rate of net assimilation (r= 0.90**) and the weight of fruit weight per hectare (r= 0.51**). This study revealed that the application of coconut husk organic fertilizer from liquid organic fertilizer waste at high doses could increase the growth and yield of eggplant.
