One of the central themes in plant nutrition is to find the particular growth stage when supply of a particular nutrient leads to highest yield per unit amount of the absorbed. Partial productive efficiency of nitrogen for grain production is defined as: Partial productive efficiency of nitrogen absorbed at period (n-1) to (n) = [Y(n) […]

In this article we will discuss about the properties of lowland rice soils. Land submergence for lowland rice brings about various changes in soil, which distinguish it from its upland counterpart. One of the most outstanding characteristics of flooded (lowland) soils is the absence of oxygen in the root zone. The diffusion of oxygen into […]

The importance of harvesting and postharvest management is underscored by the fact that large losses of crop yield occur due to poor handling techniques. Therefore, harvesting, drying, milling and storage should receive serious attention. i. Harvesting and Threshing: In tropical Asia, rice harvesting is carried out by manual labour. Rice plant is cut with a […]
