Publikováno v: Agronomy Journal. 85:316-321

Vast areas of rice-growing (Oryza sativa L.) lowlands in Asia are fallowed or cropped with non-rice crops for part of the year. Nitrate can accumulate during the fallow or non-rice crop, but this nitrate can be lost upon flooding for rice production.

Source–sink relations and effects of post-anthesis canopy defoliation in wheat at low latitudes

Autor: P. K. Aggarwal, R. A. Fischer, S. P. Liboon

Publikováno v: The Journal of Agricultural Science. 114:93-99

SUMMARYSource–sink balance was studied by imposing different canopy defoliation treatments on wheat crops grown in Los Banos (Philippines) in 1985/86 and 1986/87, Sonora (Mexico) in 1972/73 and 1974/75 and New Delhi (India) in 1987/88. The crops we

Publikováno v: The Journal of Agricultural Science. 101:699-710

SUMMARYSix dryland crops (mungbean, cow pea, soya bean, groundnut, maize and sorghum) and two rice cultivars (C·171·136 and IR 36) were grown under rainfed and irrigated conditions on a dryland site with a clay loam soil at the International Rice R
