Zn Application Methods on Utilization of P Under Rice-wheat Crops

Rice and wheat both are exhaustive feeders of nutrients. Which remove more phosphorus than many other cropping systems. Therefore studies on the fate of the applied chemicals are worthwhile. Phosphorus management in rice-wheat cropping system involves an array of factors related to the crops soils fertilizers and management practices. A Knowledge of the transformations of applied phosphorus in the soil is of great importance as the availability of this nutrient for uptake by crop is governed by the proportional distribution of the various forms of phosphate compounds. The goal of this book is impart to the students a throughout understanding to the effect of zinc fertilizer application on utilization of phosphorous fertilizer under rice-wheat sequence. Thus the following objectives of this book 1.To investigate the effect of Zn and P fertilization on the yields of rice and wheat. 2.To study the effect of Zn and P application on the concentration of Zn and P in flag leaves grains and straw of rice and wheat and their uptake by rice and wheat crops. 3. To study the effect of Zn and P fertilization on the utilization efficiency of Zn and P fertilizers in rice-wheat rotation.
