Description |
A field experiment was conducted during kharif 2015 at Rice Research Station, Kaul (Kaithal) of CCS Haryana Agricultural University, Hisar to study the effect of different dates of transplanting on growth, yield, quality and economics of non scented rice varieties. The experiment comprised three dates of transplanting viz. June 15, July 05, and July 25 in main plots and four non scented rice varieties viz. HKR-48, HKR-47, HKR-127 and HKR-128 in sub plots conducted in split plot design with four replications. Experimental soil was clay loam in texture alkaline in reaction having high pH (8.1), low in organic carbon (0.32 %), low in N (161 kg/ha), medium in P (16.2 kg/ha) and high in K (328.2 kg/ha). The early transplanted crop (June 15 and July 05) recorded significantly higher number of tillers, dry matter accumulation, leaf area, CGR, RGR, yield and yield attributes than late transplanted crop (July 25). But late transplanted crop (July 25) gave higher hulling, milling and head rice recovery than early transplanted crop. The two early dates (June 15 and July 05), being at par, were significantly superior to July 25 in respect of grain yield. The interaction between dates of transplanting and non scented varieties of rice was found significant which revealed that the reduction in grain yield about 30 per cent when delay in transplanting from June 15 to July 25. The extent of reduction in grain yield was less (23%) in early duration variety HKR-48 than mid early duration variety HKR-47 (30%) and medium duration varieties HKR-128 (31%) and HKR-127 (32%) when time of transplanting delayed from June 15 to July 25. The medium duration variety HKR-128 was superior in respect of all parameters than HKR-127, HKR-47 and HKR-48. HKR-128 recorded significantly higher yield (69.67 q/ha) than HKR-127 (66.04 q/ha), HKR-47 (63.82 q/ha) and HKR-48 (52.65 q/ha). The maximum net return (Rs. 24020/ha) and B:C (1.27) was obtained by June 15 transplanting followed by July 05 (Rs. 22305/ha and 1.25, respectively) and July 25 (Rs. -10403/ha and 0.88, respectively). The HKR-128 gave the highest net return (Rs. 22640/ha) and B:C (1.25) as compared to other varieties. |
