Abstract
It is indisputable that adaptation of optimum soil and water management practicies plays an important role in stepping up the productivity of crops in arid and semiarid regions and accordingly has its impact on the national economy.
Maximum benefits of sandy soil are derived from a fertility programme only where it is coupled with other management practices that ensure the most suitable conditions for plant growth. These include the use of adapted and highly productive plant varieties in addition to the correction of problems due to salts or poor physical conditions. The lack of irrigation water in well—drained soils of dry regions and even undue water loss by deep percolation, run—off and evaporation can be avoided by adopting any of the specific irrigation systems as sprinkler and furrow methods.
Leguminous plants such as broadbean (Vicia faba L.) and groundnut (Arachis hypogaea U.) are thought to be successfully grown in the newly reclaimed sandy soils as cash crops. But soil productivity is definitely limited by irrigation water with regard to its source, quality and cost. It is, therefore, very important that farmers must be well aware of such proper agrotechnical methods as soil cultivation, modern irrigation techniques and fertilizers management.
Pandey et al. (1984 a) reported that in spite of the
crop’s reputed drought tolerance, information on groundnut growth phases that more sensitive to moisture stress is still inadquate for the purpose of management practices which ultimately produce more efficient use of irrigation water. The situation is also so with other crops.
As the NPK concentrations and uptake are considered as good diagnostic parameters affecting yield which, in turn, depend on optimum combinations of irrigation methods, soil moisture regime and soil fertility, it is therefore thought to establish an experiment to achieve the following objectives:
1. To Study the effect of irrigation methods, viz., (Sprinkler and furrow), interacting with soil moisture levels and phosphatic fertilization on some chemical properties of sandy soil.
2. To study the effect of the aforementioned factors on soil and plant NPK status.
3. To study the yields of broadbean and groundnut and their components as affected by soil and water
management practices.
4. To study the effect of soil and water management practices on amino acid and fatty acid composition of broadbean and groundnut to assess the seed quality as well.
5. To study the overall effect of soil and water management practices on water use efficiency.
