ABSTRACT: Mean grain yield of flooded rice in southern Brazil has increased in recent years due to the use of high-yield cultivars and improvement of crop management practices. Nevertheless, stagnation in grain yields has been observed in some rice-producing regions. Adoption of conservation tillage systems based on cover crops may be a strategy to increase rice grain yield potential. The objective of the present study was to evaluate the effect of winter cover crops on initial establishment, development, and grain yield of flooded rice (Oryza sativa L.) grown under different fertilization levels and no-tillage. A field experiment was carried out for three consecutive years (2010/11, 2011/12, and 2012/13) in Cachoeirinha, Rio Grande do Sul, South Brazil.... |

In order to research on Leaf Area Index (LAI) in the recommended rice varieties with different rate of fertilizer application during 2014 at Khlong Luang Rice Research Center. An experiment as Split plot in RCB with 4 replications, main plot were 3 recommended rice varieties: RD49 RD31 and PTT1 and sub plot were fertilizer application rates : 0-0-0 12-6-6 and 30-6-6 N-P2O5-K2O kg per rai. Character measured was Leaf Area Index (LAI) in 3 recommended rice varieties at 30 50 70 90 days after planting. The result indicated that RD49 RD31 and PTT1 rice varieties Leaf Area Index maximum for 3 varieties was obtained at flowering stage (80 days after transplanting) and then it was reduced due to the wilting and falling of lower leaves. RD49 had the highest LAI... |
