Description The present study entitled “Response of basmati rice cultivars to different levels of nitrogen
and phosphorus” was carried out at Farm of College of Agriculture, Kaul (Kaithal) Chaudhary Charan
Singh Haryana Agricultural University, Hisar during kharif season of 2010 on clay loam alkaline soil,
low in organic carbon and available nitrogen, medium in phosphorus and high in potassium. The
treatments consisted of four cultivars (CSR-30, HKR03-408, Pusa Basmati-1 and Pusa Basmati-1121)
and six NP levels laid out in split-plot design with three replications, keeping cultivars in main plots and
NP levels in sub plots. Thirty days old seedlings of the crop were transplanted mainly on a well puddled
soil at a hill spacing of 20 cm x 15 cm with two seedlings per hill. The studies revealed that the tall
cultivars (CSR-30 and HKR03-408) took longer time to attained 50% flowering and maturity than semi
dwarf cultivars (Pusa Basmati-1 and Pusa Basmati-1121). The number of tillers increased with the age
of crop up to 60 days after transplanting (DAT) and thereafter, slight reduction was recorded at 90
DAT. Dry matter accumulation increased with the advancement of crop stages and maximum increase
was observed during 60-90 DAT. The semi dwarf cultivars produced more tillers/m2 than taller
cultivars but reverse was true for dry matter accumulation and head rice recovery. Pusa basmati-1121
was found best as it gave the highest grain yield, net income, benefit cost ratio, longest kernel and
length breadth ratio than all other cultivars. Pusa Basmati-1121 showed maximum uptake than tall
cultivars. Increasing NP levels significantly increased all the crop growth parameters viz. plant height,
tillers/m2, dry matter accumulation. The yield contributing characters (panicles/m2, grains/panicle),
yield (grain and straw), net profit and benefit cost ratio were higher with N90P45 kg ha-1. Application
of N90P45 kg ha-1 also showed highest nitrogen and phosphorous uptake.
