PENGARUH BEBERAPA PAKET PEMUPUKAN DAN AMELIORASI TERHADAP PERTUMBUHAN DAN HASIL TANAMAN KACANG TANAH (Arachis hypogaea L.)

Wetlands in Peatland Development Area has potential for the development of paddy, vegetables and palawija. Development of the commodities are limited or restricted by many limiting production factors such as nutrients, water and plant varieties. The purpose of this study is to know the influence of amelioration and fertilization packages on the growth and yield of peanuts in the swampland peat land development area. The treatments consisted of four amelioration and fertilization package i.e.: (1) Farmerâs package I: 250 kg.ha dolomite, (2) -1 -1 -1 -1 Farmerâs package II: 2.5 t.ha straw compost+18 kg.ha P2O5+300 kg.ha fly ash, (3) Recommendation package: 1.0 t.ha dolomite+22.5 -1 -1 -1 -1 -1 -1 kg.ha N + 36 kg.ha P2O5, and (4) Research package: 2.0 t.ha dolomite+22.5 kg.ha N+22.5 kg.ha P2O5 +30 kg.ha K2O. The result showed that the growth of plants (plant height and number of branches) does not differ between treatments, and the obtained peanut pod yield improvement is 50.45% in the research package treatment compared to Farmerâs package I.

PENGELOLAAN AIR, BAHAN ORGANIK DAN VARIETAS ADAPTIF UNTUK MENINGKATKAN HASIL PADI DI LAHAN RAWA PASANG SURUT [Water Management, Organic Matter Application and Using Adaptable Variety to Increase Rice (Oryza sativa L.) Productivity on Tidal Swamp Land] Koesrini, Koesrini; Anwar, Khairil

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 Â 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 Â 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 Â 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 Â 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.Â

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.
