RICE CULTURE Nitrification Inhibitors Influence on Rice Grain Yield and Soil Inorganic Nitrogen Fractions
Nitrogen source and application time recommendations for rice are currently limited to applying an NH4-forming N source to a dry soil surface at the 5-lf growth stage for producers utilizing the delayed-flood production system. Fertilization trials were conducted at the Rice Research and Extension Center (RREC) and the Pine Tree Branch Station (PTBS) to investigate the use of urea amended with ...
متن کاملNitrogen Dynamics and Fertilizer Use Efficiency in Rice Using the Nitrogen-15 Isotope Techniques
Nitrogen-15 ( N)-labeled biogas slurry (digested anaerobic organic residues (DAOR)) and chemical 15 fertilizer (CF) were applied to soil with low fertility cropped with rice. The N dilution method was used to 15 estimate the N uptake and recovery; potted soil was labeled with 1.0 atom % excess [ N] ammonium chloride 15 NH Cl. Certain select soil characteristics were also measured in soil amende...
متن کاملTropical Legume Crop Rotation and Nitrogen Fertilizer Effects on Agronomic and Nitrogen Efficiency of Rice
Bush bean, long bean, mung bean, and winged bean plants were grown with N fertilizer at rates of 0, 2, 4, and 6 g N m(-2) preceding rice planting. Concurrently, rice was grown with N fertilizer at rates of 0, 4, 8, and 12 g N m(-2). No chemical fertilizer was used in the 2nd year of crop to estimate the nitrogen agronomic efficiency (NAE), nitrogen recovery efficiency (NRE), N uptake, and rice ...
متن کاملProspects for Genetic Improvement to Increase Lowland Rice Yields with Less Water and Nitrogen
Increasing yield potential of lowland rice remains to be the top priority in rice geneticimprovement programmes, because rice farmers’ primary concern is still grain yield and world rice production has to increase by 1% annually in the next 20 years to meet the demand of the growing population. Improvements in yield potential of irrigated lowland rice were achieved under ample supply of water a...
متن کاملSynergy and Transition of Recovery Efficiency of Nitrogen Fertilizer in Various Rice Genotypes under Organic Farming
Despite the growing demand for organic products, research on organic farming (OF) such as genotype screening, fertilizer application and nutrition uptake remains limited. This study focused on comparisons of the apparent recovery efficiency of nitrogen fertilizer (REN) in rice grown under OF and conventional farming (CF). Thirty-two representative conventional Japonica rice varieties were field...
