Abstract: |
Six genotypes ofupland rice were planted at research station ofRARS, Dati during 2011/12 and the experiment was replicated three times. The experiment was laid out in randomized complete block design. Amongst the genotypes included in the experiment, RR 443-2 (2253 kg/ha) identified as promising genotype of upland rice. Difference in grain yield due to genotypes was not found significant. Similarly, eighteen genotypes of upland rice were planted at the research station of RARS, Dati during 2012113 . Randomized complete block design was followed and replicated three times. £R83383-B-B-141-2 produced the highest grain yie ld (4649 kg/ha) followed by IR81025-B-16-l (4522 kg/ha) and IR83383-B-B129-3 (4488 kg/ha). Among them, twelve genotypes produced grain yield more than 4 t!ha and identified as promising genotypes for far western mid hills agro-environment. However, the differences in grain yield due to genotypes was found non -significant but traits like days to flowering, maturity and plant height were found significantly different. Similarly, seven genotypes of normal rice were planted in farmers' field of Bhumirajmandu, Dati during 2011112 and 2012/ 13. The experiment was conducted at four farmers' field . Each farmer is considered as a replication during data analysis. Out of the genotypes included in the experiment in the year 2011112, NR 10676-B-1-3-3-3 produced the highest grain yield (4708 kg/ha) followed by NR 10585-B-B-4-3-2 (4291 kg/ha) and NR 10591-B-B-3-3-3 (4062 kg/ha) respectively. While in 2013, NR I 0548-4B-22-2-l produced the highest grain yield (4749 kg/ha) followed by khumal-4 (4687 kglha) and NR 10585-B-B-4-3-2 (4562 kg/ha) respectively. Statistically, the difference in grain yield due to genotypes was found nonsignificant. Combined analysis over year was also carried out. Genotypes NR I 0676-B-1-3-3- 3 (4520 kg/ha) and NR 10585 -B-B-4-3-2 (4426 kg/ha) identified as promising genotypes of normal rice for far western mid hill agro-environment. The effect of treatment and year was found significant at 5% level whereas the interaction effect of treatment and year was found non- significant. |
