Phosphorus and Iron Deficiencies Influences Rice Shoot Growth in an Oxygen Dependent Manner: Insight from Upland and Lowland Rice
Rice is the main staple crop for one-third of the world population. To maximize yields, large quantities and constant input of fertilizers containing essential nutrients such as phosphorus (P) and iron (Fe) are added. Rice can germinate in both aerobic and anaerobic conditions, but the crosstalk between oxygen (O₂) and nutrients such as P and Fe on plant growth remains obscure. The aim of this ...
متن کاملEffect of Phosphorus Supplementation to Ammoniated Rice Straw on Rumen Fermentability, Microbial Protein Synthesis and in vitro Nutrient Degradability
The effect of phosphorus supplementation to ammoniated rice straw was studied. The in vitro experiment was carried out following the first stage of Tilley and Terry method. The treatments consisting of four diets were A= 50% ammoniated rice straw + 50% concentrate (control), B= A + 0.2% phosphorus (P) supplement, C= A + 0.4% phosphorus (P) supplement, and D= A + 0.6% phosphorus (P) supplement o...
متن کاملRice Response to the Time and Rate of Potassium Fertilization
Rice (Oryza sativa L.) requires adequate potassium (K) nutrition for optimal growth, grain yield, and disease resistance. Studies were conducted in 2001 and 2002 at the Pine Tree Branch Experiment Station (PTBS) to characterize K uptake by rice and investigate the effect of both K-fertilizer application rate and time on rice growth, K uptake, and grain yield. Potassium fertilizer was applied at...

15 صفحه اولGenotypic Differences in Potassium Nutrition in Lowland Rice Hybrids
China imports most of its potassium (K) requirements for crop production. The objective of this study was to evaluate indica rice hybrids for Kuse efficiency. Twenty-eight indica rice hybrids were evaluated in nutrient solution. The K influx rate was greatest in genotype Weiyou 64 (684.9 nmol K plant h) and least in genotype Xie A/909 (457.2 nmol K plant h). The K-use efficiency was greatest in...
