Rice is the major foodgrain of the world and it is the principle cereal consumed in India and other parts of Asia1. Milling of paddy to obtain edible rice grain yields two major byproducts of economic and nutritional importance, namely, paddy husk and rice bran. Paddy husk has no food value but has several industrial uses. Rice bran, on the other hand, can serve as an animal feed, as a human fo...

paddy de-awning using a de-awner increases the uniformity and flow rate of paddy grains through the orifices of hoppers, bucket elevators and chutes. in this study the effects of paddy variety, rotational blade speed and moisture content on performance of a prototype de-awner machine were investigated. the experiment was conducted in a factorial design with three factors, variety (hashemi and b...

Paddy soils are classified as wetlands which play a vital role in climatic change and food production. Soil carbon (C), especially soil organic C (SOC), in paddy soils has been received considerable attention as of recent. However, considerably less attention has been given to soil inorganic carbon (SIC) in paddy soils and the relationship between SOC and SIC at interface between soil and the a...

Women are involved in planting, transplanting, weeding, harvesting and processing activities in paddy cultivation system. These operations are most drudgeries activities performed by them. During these operations the women face many physical and physiological problems. Keeping this in view the physical strain with respect to working heart rate (WHR), Oxygen consumption rate (OCR), Energy expend...

Knowledge of the area and spatial distribution of paddy rice is important for assessment of food security, management of water resources, and estimation of greenhouse gas (methane) emissions. Paddy rice agriculture has expanded rapidly in northeastern China in the last decade, but there are no updated maps of paddy rice fields in the region. Existing algorithms for identifying paddy rice fields...

This study investigates percolation and seepage through the bunds of flat and terraced paddies. Field experiments were conducted in Hsin-Pu of Hsin-Chu County, Taiwan, to measure the soil water content of various types of bund. Measurements revealed that the soil was unsaturated along the sloped surface of the terrace. Experimental results also indicated that seepage face flow did not develop e...

Dissimilatory Fe(III) reduction is a universal process with irreplaceable biological and environmental importance in anoxic environments. Our knowledge about Fe(III) reduction predominantly comes from pure cultures of dissimilatory Fe(III) reducing bacteria (DFRB). The objective of this study was to compare the effects of glucose and a selection of short organic acids (citrate, succinate, pyruv...

The study of greenhouse gas emissions has become a global focus, but few studies have considered saline-alkali paddy fields. Gas samples and saline-alkali soil samples were collected during the green, tillering, booting, heading and grain filling stages. The emission fluxes of CO2, CH4, and N2O as well as the pH, soil soluble salt, available nitrogen, and soil organic carbon contents were detec...

In an agriculture field paddy is one of the major staple foods in the Asian countries like China, India, Indonesia, and Bangladesh etc. But paddy disease likes a Blast; Bacterial Leaf Blight; Rice tungro etc. stops the growth of the paddy trees. If the diseases are not detected at an early possible stage then there is a decrease in the production of paddy. In this paper a noble methodology i.e....

Website : www.jphmr.com Quick Response Code : for more than 3 million people in Asia, and India ranks next only to China in Paddy production (about 40% of total grains). Since paddy cannot be consumed raw and needs to be processed, more than 1.5 lack rice mills are functioning in India (2005-06), employing a 14 significant number of population . This population is at risk of exposure to grain d...
