A body of descriptors of the rice crop system was collected in a sample of farmers' fields in Central Luzon, Philippines, and these data were used to characterize cropping practices and pest constraints. The analysis was conducted in four steps: (1) the time-dependent, quantitative information ...
Yields were greater for the post-rice than for the pre-rice season. Partial irrigation increased long-term biomass compared with those for strictly rainfed situations by 30% in the pre-rice season and by 104% in the post-rice season. Yields were more stable at Davao than at Los Baos or ...
Results indicate that the baseline system (single-crop aman season rice) was the least productive, while double cropped systems increased rice equivalent yield 72–217%. Despite gains in productivity, higher cropping intensity reduced resource use efficiencies due to higher inputs of fertilizer and ...
Estimating Carbon Capture Potential of Fallow Weeds in Rice Cropping Systems Weeds occurred during the fallow season can well perform the function of carbon (C) capture due to receiving little human disturbance. This study aimed to ... G Chen,Y Kang,F Cao,... - Phyton (0031-9457) 被引量...
The first new rice cultivars released during 1966–1971 were all susceptible to both vector and RGSV. Effective sources of resistance to both were found and incorporated into new varieties that were released in 1974–1975. These were at first grown widely and successfully in the Philippines, ...
Low-cost protected cultivation: enhancing year-round production of high-value vegetables in the Philippines Thirty-four protected-cropping structures of various designs were constructed and tested at five project sites in Leyte, the Philippines, to evaluate their technical feasibility for producing vegetabl...
In tropical rice (Oryza saliva L.) lowlands, soil NO, is lost during the transition from the dry to the wet season. To understand how soil and crop management influences NO, loss, we examined NO, dynamics during a 2-yr period in an Alfisol in the Philippines: weedy, weedfree, and ...

(1992)withL. leucocephalahedgerows at 10 m spacing highlighted the decline for annual runoff and soil loss by six- and 24-fold, respectively, compared with a control of cassava plots. In the Philippines,Paningbatan et al. (1995)recorded a significant reduction in soil loss with leguminous ...
Field surveys were conducted during the wet season (May to December) of 2016 in two districts of each of the four main rice-growing provinces. The intensity of injuries caused by pests (diseases, insect pests, rodents and weeds) and yield were assessed in farmers’ fields. Data on cropping...
