Abstract

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.

Abstract

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’s package I: 250 kg.ha dolomite, (2) -1 -1 -1 -1 Farmer’s 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’s package I.

Abstract

Adoption was a process of behavior change either in the form of knowledge, attitudes  and  skills  in  a  person  in  accepting  innovation  delivered  by  farming educator.The  research  objective  was  to  determine  the  level  of  Inpara  adoption   in swampyland with information output of Inpara adoption varieties in swampylands.The research  was  conducted  in  swampyland  on  Tapin  and  Hulu  Sungai  Utara  (HSU) district  during  February  to  May  2015.Total  sample  of  60  people  selected  randomly distributed in the six villages.  Data were analyzed descriptively both qualitative and quantitative  data  with  scoring  techniques.Results  showed  that  the  level  of  Inpara adoption  on  swampyland  remained  low,  i.e.  66.88%/year  on  HSU  district  and  (-74.56%/year) on Tapin district.The low level of adoption was due to the selection of varieties  that  had  been  developed  in  swampland,  namely  Ciherang,  Mekongga  and some  numbers  Inpari  adaptive  and  dissemination  of  varieties  Inpara  not  widely distributed to  swampyland  area.Despite the level of knowledge of  farmers on Inpara varieties was relatively high (68.3%) and attitudes of farmers toward Inpara varieties innovation  were  classified  agree  (72.9%),  not  yet  ensure  increased  adoption  of Inpara varieties in the two districts.
