  The experiment was conducted in four cemented tanks of four guar genotypes i.e. S-807, Esser, Brooks and S-1183, under different water regimes (control, pre-post flowering stress, and terminal stress). The treatments were imposed at different stages of growth. Photosynthetic efficiency was determined by measuring leaf area, chlorophyll content and seed/yield. The findings show that water deficit reduced seed yield leaf area and chlorophyll content in all four guar genotypes. However, the genotypes S-807 and Esser had comparatively better performance than the other genotypes tested i.e. Brooks and S-1183.

  Nutrient depletion in the farm land areas has brought terrible devastation in some cropping areas of a country. There is no vegetation whatever, despite adequate rainfall and chemical fertilizers are now re-vegetating such areas. They have rapidly overtaken organic matter as a chief source of nutrients and expert opinion believes that such external nutrients source are the only way to sustain the food requirement of the population. If sustainability is to be maintained as the first priority, then other important components such as efficiency of input use, economic return and environmental protection can all be used appropriately as part of the sustainability phenomenon.
