The effect of water deficits on growth and yield of rice depend on the stage of crop growth at which the water deficits occur. i. Vegetative Growth Stage: Immediately after transplanting, adequate land submergence (5 cm) is necessary to prevent damage to establishing seedlings from high winds and for root development. Following the early rooting […]

In this article we will discuss about the growth and development of rice. 1. Roots: Rice form a fibrous root system consisting of seminal, nodal and lateral roots. Seminal roots originate from embryo, whereas nodal roots emerge from stem. Both produce numerous lateral roots. On germination, the primary root emerges followed by two additional seminal […]
How to Calculate Partial Productive Efficiency of Nitrogen ? | Agronomy
Article shared by :
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) […]
