متن کاملevaluation of herbicide application and seeding rate on competition between rice (oriza sativa l.) and barnyard-grass (echinochloa crus-galli(
in this experiment which was conducted at a field of ramin agriculture and natural resources university (khouzestan, iran) in 2005, the effect of molinate at 0 (weedy check), 2.16, 3.6 and 5 kg/ha and seeding rate of 100, 120 and 140 kg/ha was evaluated on the competition between rice and barnyard grass (echinochloa crus-galli) in a split plot design with four replication. the interaction effec...
متن کاملThe potential for carbon bio-sequestration in China's paddy rice (Oryza sativa L.) as impacted by slag-based silicate fertilizer.
Rice is a typical silicon-accumulating plant. Silicon (Si), deposited as phytoliths during plant growth, has been shown to occlude organic carbon, which may prove to have significant effects on the biogeochemical sequestration of atmospheric CO2. This study evaluated the effects of silicate fertilization on plant Si uptake and carbon bio-sequestration in field trials on China's paddy soils. The...
متن کاملImpact of 15N-labeled rice straw and rice straw compost application on N mineralization and N uptake by rice
Incorporation of plant residues in soil affects N and C content and dynamics. This studydetermined the effects of short-term alternative rice (Oryza sativa L.) residue management on Nmineralization and uptake by rice. Pot and laboratory incubation experiments were established byincorporating 15N-labeled rice straw and rice straw compost in paddy soil. The 15N recovered by riceaveraged 16.6%; mo...
متن کاملeffects of split application and nitrogen fertilizer levels on n-use efficiency in rice (oryza sativa l. cv. khazar)
effects of nitrogen fertilizer levels on agronomic efficiency (ea), physiological efficiency (ep), and recovery efficiency (er), in rice (oryza sativa l.) cv. khazar was investigated in a rcbd of three replications in a sandy soil in guilan province, iran in 2003. this study compared the effects of six n rates, namely: control (no n fertilizer), 40 (basal), 40+40 (basal + midtillering), 40+20+2...
