Research ArticleOpen accessAll words, across the recordPhysical Characteristics of Maize Cob Briquette under Moderate Die PressurePatomsok WilaiponThe potential energy content of maize cob available in Thailand was calculated based on maize productivity, the residue-to-product ratio and the heating value of maize cob. It was found that the computed value was about 74.2 PJ/year. Besides, the potential energy value exceed 1,000 TJ/year was also reported for the case of five provinces of Thailand. Concerning with maize cob … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 8,091 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPhosphorus Biogeochemical Cycling in a Sugar Cane AgroecosystemD. Sequera, D. Lopez-HernandezThe annual harvest of sugarcane plantations together with the burning of the crop before harvest, a common practice of management of sugarcane plantations in South America, leads to the loss of significant amounts of nutrients in those agroecosystems. Thus prescribed burning operations could progressively diminish the level of soil organic matter and increase nutrient deficiency in soils of sugar cane … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 29 Jan 2013 · 7,547 accessesView PDF Cite

Fauziah, M.H.A. HusniProblem statement: For a number of geological reasons a proportion of the present coastal plains in the Malay Peninsula were inundated by seawater in the past when pyrite in some of the soils is believed to have been mineralized.

Research ArticleOpen accessAll words, across the recordUsing Soil Plant Analysis Development Chlorophyll Meter for Two Growth Stages to Assess Grain Yield of Malaysian Rice (Oryza sativa)Asa Gholizadeh, Mohd Amin Mohd Soom, Anuar Abd. Rahim, Aimrun WayayokProblem Statement: Proper yield management in rice influences grain quality and quantity. Nitrogen site-specific management is also effective on final product of crops because excessive nitrogen application at any growth stage can reduce yield and increase disease incidence. In contrast, suboptimal nitrogen levels at discrete growth stages may substantially reduce plant productivity. The nitrogen status at specific growth stages may … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 11,822 accessesView PDF Cite
