Abstract

Iron toxicity is a factor causing low rice yield on tidal swamp land (TSL).Soil quality improvement by using water management, organic matter and introducing adaptable varietywere some options to increaseits productivity in the soils. Field experiment was conducted to  evaluate effects of applying water management, organic matter and adaptable variety to increase its productivity on a TSL of KP Belandean, Barito Kuala District of South Kalimantan, during dry season of 2010. The research was arranged in a split-split-plot design with three  replicates. The main plots were two water management, i.e: P0 = without water management (control) and P1= intermittent water management, while sub plots were three organic matter application, i.e: B0 = without organic matter application (control), B1 = straw  compost 3 t/ha, B2 = manure 2 t/ha, and sub sub plots were five rice varieties, i.e. V1 = Mekongga, V2 = Inpari 1, V3 = Ciherang, V4 = Silugonggo and V5 = Margasari. The result showed that there was interaction between water management and variety tested on rice yield in TSL. The highest yield was reached by Inpari 1 variety which treatment intermitten water management, with  yield i.e. 5.390 t/ ha.Silugonggo and Ciherang was not suitable to cultivate on TSL. The implication of this research was variety recomendation on a tidal swamp land, i.e. Inpari 1 variety and intermitten water management.

Abstract

Inpara is a rice variety rice released by the Indonesian Agency for Agricultural Research and Development (IAARD) which is adaptive to swamp land. The research objective was to evaluate the adaptability and yield performanceof Inpara varieties in swamp lands. The field experiment was conducted in tidal swamp lands, in Barito Kuala District and in swampy lands, Hulu Sungai Selatan District of South Kalimantan, during dry season of 2014. The research was arranged in a randomized complete design with three replications. The treatment was 7 Inpara varieties, i.e. Inpara 1, 2, 3, 4, 5, 6, 7 and comparison varieties, i.e Margasari in tidal swamp lands and Ciherang in swampy lands. The result showed that there was a variation adaptation between Inpara varieties in tidal swamp land and swampy lands. Inpara 2 and Inpara 3 varieties showed a good adaptation in tidal swamp lands, had the yield of 4.04 t/ha which an increasing yield was 35.9% higher than Margasari variety. Inpara 1 and Inpara 6 varieties presented a good adaptation in swampy lands that produced 2.118 t/ha and 2.275 t/ha and 1.9% and 9.5%, respectively higher than Ciherang variety. Variety of Inpara is not adaptive in swamp lands.
