Growth and yield of new hybrid rice in irrigated and rain-fed lowlands
Two experiments were conducted at (i) irrigated lowland, village of Bojong, Cikembar, Sukabumi Sub-district, Indonesia, from November 2011 to February 2012, and (ii) rain-fed lowland, village of Sanca, Gantar sub-district, Indramayu, Indonesia, from April to July 2012. The objective of the experimen...

| description | Two experiments were conducted at (i) irrigated lowland, village of Bojong, Cikembar, Sukabumi Sub-district, Indonesia, from November 2011 to February 2012, and (ii) rain-fed lowland, village of Sanca, Gantar sub-district, Indramayu, Indonesia, from April to July 2012. The objective of the experiment was to determine the yield of drought-tolerant hybrid rice genotypes. A randomized block design with three replications was used. The treatment consisted of 8 hybrid rice genotypes (BI485A/BP3, BI485A/BP5, BI485A/BP10, BI485A/BP12, BI485A/BP15, BI599A/BP5, BI599A/BP15 and BI665A/BP6) and 2 check varieties (Hipa 7 and Ciherang) for the experiment in irrigated lowland, 4 hybrid genotypes (BI485A/BP3, BI485A/BP12, BI485A/BP15 and BI599A/BP15) and 3 check varieties (Hipa 7, IR64 and Limboto) for the experiment in rain-fed lowland. On irrigated lowland, all tested-genotypes produced grain yield per hectare, which was not significantly different from the check varieties Ciherang and HIPA 7. The yield of genotype BI485A/BP12, BI485A/BP15 and BI559A/BP15 under irrigated lowland showed non-significant different with check varieties Ciherang and Hipa 7, i.e 5.63, 6.87, and 6.30 tons ha-1, respectively. Genotype BI599A/BP15 under severe drought rain-fed lowland yielded 0.90 tons of grain ha-1, whereas Hipa 7 (hybrid variety, suitable for rain-fed lowland) and Limboto (drought-tolerant check variety) reached 0.34 and 0.29 tons ha-1, respectively. Genotype BI599A/BP15 is a new hybrid genotype that potential for advanced development in rain-fed lowland and in irrigated lowland with a high yield potential and quiet early-maturity age. |
