Management of Fertilizer Nutrients Other Than Nitrogen in the Semiarid Tropics of India
1988
Tandon, H L S | Rego, T J
Available information on the management of fertilizer nutrients other than nitrogen in the semiarid tropics (SAT) of India (about 96 million ha) is reviewed. Crop responses to fertilizer nutrients are high under dryland conditions. Phosphorus and then zinc are of major importance for the nonirrigated SAT, but significant yield responses to potassium and sulfur, in addition to P and Zn. are also obtained under dryland conditions in the reddish brown lateritic soils of the Bangalore area. Iron chlorosis is increasingly being mentioned as a problem in the SAT. Available information on P, K, S, Zn. and Fe has been reviewed by continuously searching for information applicable to rainfed systems in irrigation-oriented overall research in nutrient management and soil fertility even for major dryland crops. Suggestions for further research have been made for the nutrients reviewed.
