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 [...]
In the arid region with low and erratic rainfall, high temperature and unfavourable soil conditions pose severe restrictions on the use of land for arable cropping. In the rainfall zone of less than 250 mm, silvi-pasture, pasture, horti-pastoral and silviculture rather than arable cropping has been regarded as best systems for soil management and better production. In the rainfall zone [...]
