Abstract
Phosphorus (P) deficiency is one of the yield-limiting factors in Vertisols in various part of the world. The objective of this study was to evaluate the growth and P-use efficiency of 16 wheat genotypes at four phosphorus levels (Control, 40, 80 and 120kg P ha-1). Plant height, total tillers, effective tillers, test weight and phosphorus use efficiency were significantly affected by wheat genotypes and phosphorus levels. On the basis of P-use efficiency, genotypes were classified as efficient and responsive, efficient and nonresponsive (ENR), nonefficient and responsive (NER), and nonefficient and nonresponsive (NENR). Genotypes which produced higher effective tillers in a low level of phosphorus and respond well to added phosphorus are the most desirable because they are able to express their high yield potential in a wide range of phosphorus environment. Genotype HD 2864, HD 2932, Raj 4238, HI 8113, CG Genhu 4, GW 366, GW 273, CG Genhu 4 fall into this group.
