Rice harvesting

In this study, 30 soil samples from rice farmland in Zhejiang province, in eastern China. We sampled the cultivation layer soils during rice harvest season. The soils are acidified and the average value of pH is 5.82. A sequential extraction procedure... 

Sampling sites were selected based on the regional soil survey and a related study in seven sub-areas, each with coverage of several dozen to hundreds of square kilometers and with representative geological setting and geochemical characteristics. Rice and cultivation layer soil at 146 sites were sampled at a density of one site per square kilometer during rice harvest season, October 2006.

Rice harvested from the plant with its husk intact is known as rough rice or paddy. The husk is not eaten by humans but is sometimes burned for use as an energy source. 

Making palm sugar is an occupation that many villagers in Asia do after rice harvest to earn additional income. In some instances the tree itself is tapped rather than the flowering spikes, but this is an isolated production method. The sugar palm sap containing around... 

White rice, in comparison to rough or brown rice, is low in vitamin content (cf. Table 15.38) and in minerals. A nutritionally improved product may be obtained by a parboiling process, orginally developed to facilitate seed coat removal. About 25% of the world s rice harvest is treated by the following process raw rice — steeping in... 

Some modern varieties of cereals such as wheat and rice achieve high yield potential through genetic factors for plant dwarfness that improve harvest index. A popular notion among plant breeders is that high-yielding... 

In 1995 potatoes and rice were stored in an abandoned road tunnel in Japan. At the end of the winter the tunnel was filled with snow that was covered with aluminum coated tarpaulins. The products were stored both beside the snow piles and under the tarpaulins. Rice from the same harvest was stored in a grain magazine and at a research centre for comparison. The rice in the tunnel had best quality after two month. The potatoes under the tarpaulins kept its quality longest and it was found that the storage method was feasible over the whole year (Suzuki et al., 1997). 

The most widely studied therapeutic proteins produced in plants include monoclonal antibodies for passive immunotherapy and antigens for use as oral vaccines [40]. Antibodies against dental caries, rheumatoid arthritis, cholera, E. coli diarrhea, malaria, certain cancers, Norwalk virus, HIV, rhinovirus, influenza, hepatitis B virus and herpes simplex virus have been produced in transgenic plants. However, the anti-Streptococcus mutans secretory antibody for the prevention of dental caries is the only plant-derived antibody currently in Phase II clinical trials [40]. Until recently, most antibodies were expressed in tobacco, potato, alfalfa, soybean, rice and wheat [9], It has been estimated that for every 170 tons of harvested tobacco, 100 tons represents harvested leaves. A single hectare could thus yield 50 kg of secretory IgA [3, 41]. Furthermore, it has been estimated that the cost of antibody production in plants is half that in transgenic animals and 20 times lower than in mammalian cell cul-...
