    Response of basmati rice varieties to time of transplanting
    (CCSHAU, 2009) Mukesh; Ishwar Singh
    The present study entitled “Response of basmati rice varieties to time of transplanting” was carried out at Research Farm of CCS Haryana Agricultural University Rice Research Station, Kaul (Kaithal) during kharif season of 2008-09 on clay loam alkaline soil, low in organic carbon and available nitrogen, medium in phosphorus and high in potassium. The treatments consisted of three dates of transplanting (June 25, July 10 and July 25) and four varieties (Taraori Basmati, CSR-30, Pusa Basmati-1 and Pusa Sugandha-4) laid out in split-plot design with four replications, keeping transplanting dates in main plots and varieties in sub plots. Thirty days old seedlings of the crop were transplanted mainly on a well puddled soil at a hill spacing of 20 x 15 cm with two seedlings per hill. The studies revealed that, the early transplanting (June 25 and July 10) significantly increased all the crop growth parameters viz. plant height, tillers/m2, dry matter accumulation and leaf area index over the late transplanting (July 25). The yield contributing characters (panicles/m2, grains/panicle), yield (grain and straw), net profit and benefit cost ratio were higher with early transplanting dates as compared to late planting. The late planting, however, improved the quality traits viz. hulling, milling and head rice recovery than early planting. Among the varieties, tall varieties (Taraori Basmati and CSR-30) took longer time to attain 50% flowering and maturity than semi dwarf varieties. The semi dwarf varieties produced more tillers/m2 than taller ones but reverse was true for dry matter accumulation, leaf area index, hulling, milling and head rice recovery. Pusa Sugandha-4 was found best as it gave the highest grain yield, net income, benefit cost ratio, longest kernel and length breadth ratio than all other varieties.
