Differential susceptibility of some sunflower genotypes to phosphorus deficiency in a black soil
Year: 2003
Type: article
Abstract: In a pot culture study, using phosphorus deficient black soil, four promising sunflower genotypes (KBSH-1, DSH-1, Sungene-85 and PAC-36) were tested for their differential susceptibility to the deficiency of this nutrient. Phosphorus deficiency symptoms were noticed in the hybrids KBSH-1 and DSH-1 while PAC-36 was almost free from these. The maximum grain yield response to phosphorus was recorded in KBSH-1 and the minimum in PAC- 36. Dry matter yield followed a similar trend. On the basis of yield response and P uptake the susceptibility of the genotypes was rated in the following order: PAC-36 < Sungene-85 < DSH-1 < KBSH-1.
