TO TH E EDITO R: I appreciate the comments from Wiwanitkit. I agree with him that there are many kinds of rice in the world and whether this difference leads to different reaction to the gas-trointestinal tract (GI) has not been known. The nutritional composition of rice varies depending on its variety and growing condition. Although, the quantity of its major nutrient contents such as protein,...
the effects of sodium chloride and zn rates and sources on the growth and chemical composition of lowland rice (oryza sativa l.) were studied using calcareous soil in a greenhouse experiment. the treatments comprised 5 levels of nacl (0, 12.5, 25, 37.5 and 50 mmol kg-1 soil), three zn rates (0, 5 and 10 mg kg-1 soil) and two zn sources (znso4, 2h2o and znedta). applied salinity decreased shoot ...
Relative (actual / potential) evapotranspiration (RET) was derived using ten-day composite NOAA PAL datasets (8km x 8km spatial resolution) over Indian landmass and an operational energy balance algorithm for five agricultural years (June-May) between 1996 to 2001. This was used to characterize ‘Kharif’ (June-October) rice growing environment and its yield prediction in rainfed conditions. Inve...
Submit Manuscript | http://medcraveonline.com non-rice crops in a rotation such as wheat. Therefore, puddling for rice transplanting should be avoided as it has adverse effects on the succeeding upland crops. Unpuddled transplanting is an alternative method for rice establishment which can be adopted to overcome these problems and also to reduce cost of rice production. For this system, the lan...
Rice blast disease has become an enigmatic problem in several rice growing ecosystems of both tropical and temperate regions of the world. In this study, we develop models for predicting the occurrence and severity of rice blast disease, with the aim of helping to prevent or at least mitigate the spread of such disease. Data from 2 government agencies in selected provinces from northern Philipp...
The increase of nitrite and nitrate concentrations in surface and groundwater is a greatconcern in our lives nowadays. Nitrate and nitrite in drinking water normally originate fromagricultural operation and chemical fertilizers. Therefore, the present study aims toinvestigate the effect of nitrogen fertilizers used in rice cultivation and levels of nitrate andnitrite in farm wastewater and wate...
IN THEIR REPORT “INSECT-RESISTANT GM rice in farmers’ fields: assessing productivity and health effects in China” (29 Apr., p. 688), J. Huang et al. found that farmers growing insect-resistant GM rice obtained higher yields with less use of insecticides than farmers growing conventional varieties. Huang et al.’s methodology does not, however, permit discrimination between two alternative hypoth...
Since the mid-1970s, rice consumption in Nigeria has risen tremendously at about 10% per annum due to changes in consumer preference. Most public and private sector interventions programmes at increasing the productive capacities of various factors within the system notwithstanding, domestic production has not been able to meet the local demand leading to considerable import, which today stood ...
Salinity stress is one of the most widespread soil problems next to drought, in rice growing areas. ReducingSodium (Na+), while maintaining Potassium (K+) uptake in rice are traits that would aid in salinity tolerance.Therefore, the identification of quantitative trait loci (QTLs) associated with those for Na+ and K+uptake, will enable breeders to use marker-assisted selection...
The article presents a study of water consumption rice crops during periodic watering in various interphase periods the growing season. experiments were carried out on plot 21.2 hectares rice-growing enterprise RBF "Krasnoarmeysky", geographically located Kuban irrigation system. object was an intensive variety Rapan Russian selection. subject regime season rice. It found that transition to int...
