Effect of Application of Granular Organic Fertilizer Enriched with Boiler Ash and Neem Leaves Powder on Plant Resistance Against Insect Pests

R. R. Rukmowati Brotodjojo, Dyah Arbiwati
Abstract—Plant nutrition status could affect plant resistance against insect pests. This researched aimed to study the effect of application of granular organic fertilizer enriched with boiler ash and neem leaves powder on plant resistance against insect pests. Treatment used is kind of organic fertilizer granules (A,B,C) of own products applied with various doses (10 tons/ha, 20 tons/ha, 30 tons/ha). For comparison is a control that uses inorganic fertilizers (Urea 60 kg/ha; TSP 95 kg/ha; KCl 50 kg/ha ). Plant tested were caysim against Crocidolomiapavonana larvae and Aphids sp. as well as potato against Lepidiota stigma larvae. The use of fertilizers 10-30 tons/ha can be slightly depressed L. stigma feeding. Lepidiota stigma larvae on unfertilized soil consumed more potato tuber than that of the fertilized soil. Caysim treated with inorganic fertilizers suffered more damaged caused by C. pavonana that that treated with granular organic fertilizer. Population of Aphids sp. on Caysim treated with inorganic fertilizers were higher than that that treated with granular organic fertilizer. Organic fertilizer can increase plant resistance against pest.

Index Terms—Granular organic fertilizer, plant resistance, insect pests.
