Given the vagaries of climatic and environmental constrains, increasing the net primary production is difficult in arid regions. This need to be address through different strategies including re-vegetation of degraded lands and restoring life of soil by increasing sequestration of organic and inorganic carbon. Strategies for enhancing soil organic carbon requires long term planning, which consists of selection of ideal [...]
Management of soil borne diseases depends on a thorough knowledge of the pathogen, the host plant, and the environmental conditions that favours the infection. In order for a disease to develop, all three factors must be present. The pathogen (a virulent, infectious agent) must have viable inoculum, such as zoospores, available to infect the host. The host (a susceptible plant) [...]
For maintaining the fertility status of soil and conserving the water, different types of measures or practices exist; however, agronomical practices are more suitable for the drylands because these practices do not need high technical knowledge and initial costs. The major agronomic practices are contour cultivation, tillage, mulching, dead furrow, line sowing, broad bed furrow, strip cropping and improved dryland [...]
