copound effect of CRH as organic fertilizer on rice and control of golden apple snail
INTRODUCTION
Carbonized rice hull (CRH) is made from incomplete or partial burning of rice hull. It contains micronutrient vital to growing crops. In our country, CRH is not only for local use but also for export. CRH is one of the organic materials that is fundamentally important in that they supply various kinds of plant nutrients including micronutrients, improve soil physical and chemical properties and hence nutrient holding and buffering capacity, and consequently enhance microbial activities and pest control agent. The present study attempts to know more about effect of other organic fertilizers on rice. Other organic fertilizers on rice had already been studied Chau and Heong( 2005) they used chicken and hog manure, Siavoshi (2010) used chicken manure, cow manure and chemical fertilizer. Myint et.al (2010) used cow manure, poultry manure, rice straw + urea and mineral fertilizer, but they focused only on the growth, yield and nutrient accumulation of rice. Tangkoonboribun (2009) used tobacco waste as molluscicide control of GAS in paddy fields, (Philrice) used IMO for the control of GAS and weeds in rice paddies, Massaguni&Latip (2012) used Neem crude extract as potential Bio pesticide for controlling GAS. To address the effect of CRH as organic fertilizer and control of GAS, this present study was carried out. Although many researches in this area have been done for many years, most of the research mainly focused on the impact of organic fertilizer such as chicken dung, cow manure, goat manure, carabao manure and rice compost and chemical fertilizer on major pest and yield production of rice, it generally shows that the compound effect of CRH as organic fertilizer on rice and control of GAS is still clearly have not known. Here in our locality, most of the farmers are using synthetic chemical fertilizer which is costly and lead to environmentally problems. In light of this problem, the study helps to improve and promote yielding production
