Pengaruh Pemberian Bahan Amelioran terhadap Pertumbuhan dan Hasil Cabai Merah (Capsicum Annum L.) di Lahan Sulfat Masam

High soil acidity is one of the problems causing low hot pepper yield on Acid Sulphate Soils. Using tolerant variety and application of ameliorant were some efforts to increase hot pepper yield on Acid Sulphate Soils. The objective of this research was to study the effect of ameliorant application on the growth and yield of three hot pepper varieties on Acid Sulphate Soils. This research was conducted on Acid Sulphate Soil at Barambai-Barito Kuala District-South Kalimantan on the dry season of 2004. The experiment was arranged in Split-Plot Design with three replications. The main plots were ameliorant application, i.e. control, liming 2 t.ha-1, liming 2 t.ha-1 + manure 5 t.ha-1, and the sub plots were three hot pepper varieties, i.e. Hot Chili, Jatilaba and Tit Super. The result showed that the yield of hot pepper was affected by ameliorant application, varieties and interaction between ameliorant and varieties. Liming increased yield. Hot Chili tolerated high soil acidity and had the highest yield (11.489.7 kg.ha-1) on 2 t.ha-1 liming

Penggunaan Kapur Dan Varietas Adaptif Untuk Meningkatkan Hasil Kedelai Di Lahansulfat Masam Aktual [Application of Lime and Adaptable Variety to Increase Soybean (Glycine Max Merill)productivity on Actual Acid Sulphate Soil]

High aluminum (Al) toxicity and soil acidity are the most important problems that cause low soybean productivity on actual acid sulphate soil. Soil quality improvement by using ameliorant and introducing adaptable variety are some options to increase soybean productivity in the soils. Field experiment was conducted to evaluate effect of using ameliorant and variety of soybean to increase its productivity onan actual acid sulphate soil of Simpang Jaya, Wanaraya, Barito Kuala District of South Kalimantan, during dry season of 2009. The research was arranged in a split-plot design with three replicates. The main plots were three soybean varieties, i.e. Lawit, Anjasmoro, and Argo-mulyo, while sub plots were five levels of lime i.e. K100, K80, K60, K40,K20.Result showed that liming improved soil quality and soybean yield. It significantly increased soil pH and reduced soil Al saturation. The liming also increased plant growth and yield variables (plant height, dry matter, root weight and yield) at three tested varieties. Anjasmoro was more adaptive than the others varietyon actual acid sul-phate soil

Adaptabilitas Varietas Inpara di Lahan Rawa Pasang Surut Tipe Luapan Air B pada Musim Kemarau

Tidal swamp lands are marginal lands with considerable potentials for rice farming. The key solution to overcome swampy lands constraints are nutrient and water managements as well as the use of adaptive rice varieties. Inpara (inbred swampy land rices) varieties have been released by the Indonesian Agency for Agricultural Research and Development (IAARD) which are adaptive to swampy land conditions. The purpose of this research was to evaluate the adaptability of Inpara varieties in tidal swamp lands with type B overflow. The field experiment was carried out in Karang Bunga village, Barito Kuala District, South Kalimantan Province, in the dry season from April to August 2016. The research was arranged in randomized complete block design, with 3 replicates. The varieties tested, i.e., Inpara 1, 2, 3, 4, 5, 6, 7, 8, 9, and check varieties Margasari, Ciherang, and Mekongga. The results showed that the adaptability varied among varieties tested. Inpara 3, 4, 6, 8, and 9 had high yield and good adaptation on tidal swamp land yielded 3.475-4.299 ton ha-1. These varieties produced between 38.5 to 71.3% higher than Margasari and 51.4 to 87.2% higher than Mekongga. Inpara 3, 4, 6, 8, and 9 could be used as a main varieties in the tidal swamp lands

Application of Lime and Adaptable Variety to Increase Tomato Productivity at Potential Acid Sulphate Soil

High soil acidity is the most important problem that causes low tomato (Lycopersicum esculentum) productivityat potential acid sulphate soil. Soil quality improvement by using ameliorant, such as lime, and introducing adaptable variety are options to increase tomato productivity in the soils. Field experiment was conducted to evaluate the effect of lime and varieties of tomatoes to increase its productivity in a potential acid sulphate soil of Belandean, Barito Kuala District, South Kalimantan during dry season of 2011. The research was arranged in a split-plot design with three replicates. The main plots were two tomatoes varieties, i.e. Permata and Ratna, while sub plots were five levels of lime, i.e: 0, 0.5, 1.0, 1.5, and 2.0  t ha-1. The results showed that liming improved soil quality and tomato yield. It significantly increased soil pH and reduced soil Al-saturation, and increased soil exchangeable-Ca and Mg. It was assumed that due to pyrite oxidation, however, soil pH decreased and Al-saturation increased, while soil exchangeable- Ca  and  Mg  decreased  significantly  at  nine  weeks  after  planting.  Liming  also  increased  plant  growth  and  yield variables (plant height, size, number and weight of fruit, and fruit yield) for both varieties. The better variables of Permata variety at control treatment than those of Ratna variety indicated that the first variety was more adaptive than the other variety in potential acid sulphate soil.Keywords: Adaptable variety, lime, potential acid sulphate soil, tomato.

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]

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

Pengaruh Beberapa Paket Pemupukan Dan Ameliorasi Terhadap Pertumbuhan Dan Hasil Tanaman Kacang Tanah (Arachis Hypogaea L.) Di Kawasan Pengembangan Lahan Gambut [Effect of Amelioration and Fertilization Packages on Growth and Yield of Peanut (Arachis Hypogaea L.) in Peat Land Development Area]

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) Farmer\u27s package I: 250 kg.ha dolomite, (2) -1 -1 -1 -1 Farmer\u27s 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 Farmer\u27s package I
