Abstract

Brown plant hopper outbreaks occurred again in the growing season of 2009 and continues to the present (2011). As a result of brown pant hopper, rice plants be comepuso. It is estimated more than 70% areal the rice in the ‘Golden Triangle’, name Klaten, Boyolali, and Sukoharjo crop failure. The main factors causing a population explosion is not the proper functioning of natural enemies. Natural enemies of brown pant hopper of dying from unwise use of pesticides. Actual mortality could be reduced if the natural enemies, natural enemies have a place of refuge from exposure topesticides by increasing habitat diversity in agricultural land. Research carried outaiming to see the effect of habitat manipulation in the presence of natural enemies and maintain the stability of the rice field ecosystem. The study was conducted at two locations namely rice land in the area and in Klaten Ceper Karanganom, Klaten. The results showed that the brown plant hopper populations relatively low throughout the study so it is not showing signs of damage. Natural enemy population is quite high in both locations experiments. Index of species diversity in Ceper experimental result show a high relative value. Results while the second experiment (in Karanganom) showed that land with habitat manipulation has a population of natural enemies and other insects is higher than the land without habitat manipulation.

Abstract

The research was conducted from May to November 2011 at Central Java (Karanganyar District) and East Java (ngawi district) dry land. The research was used Randomized Complete Block Design (RCBD) and with two treatments, were: sweet sorghum varieties (Numbu dan Kawali) and the kind of manure (chicken, goat, cow, kascing and without manure). The data was analyzed with randomize analisys and Duncan test. The research showed that (a) Numbu and Kawali varieties were gave same respons to growth and yield component variables, so the both varieties can be planting at Central Java (Karanganyar District) and East Java (Ngawi District) dry land; (b) Chicken manure gave the best effect to sweet sorghum growth and yield compared with control, cow, goat, and kascing manure, consist of: plant height, leaf number, root length, root volume, 1000 seed weight, stem diameter, biomass fresh weight, and biomass dry weight, juice content, and sugar content.
