Write the water demand of Groundnut crop
Answers
Explanation:
About 80% of the world groundnut production comes from seasonally rainfed areas in the semi-tropics, where climate is characterized by the low and erratic rainfall. Drought is recognized as one of the major constraints limiting groundnut productivity in these regions (Gibbons, 1980). This chapter reports various aspects of groundnut water relations, including the effect of water deficits on a range of physiological and morphological processes which affect shoot and root growth, and ultimately pod yield. Extensive reviews on this subject have been published over the past decade (for example, Boote et al., 1982; Boote and Ketring, 1990). The topics discussed in this chapter are intended to supplement and update, where necessary, the literature reviewed in these excellent papers. These reviews concentrate particularly on groundnut irrigation management and so readers are referred to them for detailed information in that area. This chapter therefore concentrates more on potential genetic and management solutions to the problem of drought in groundnut.
