Abstract

The aim of this research is to identify watershed land characteristic at Batang Bungo and to analyze land suitability for developing commodity vegetables that were dominantly utilized by the local farmer. It is found that there are 17 land units in Batang Bungo watershed, that used to be basic data to determine sample. The research showed that rubber was the main crop and green vegetables as intercropping plant. The green vegetables were planted dominantly pepper, string beans, and eggplant. These plants were cropped among young rubber plants. The land suitability analysis showed about 55790.2 ha (74,06%) of watershed wide were suitable, the rest was not suitable that by the caused by erosion hazard.   Keywords : Characteristic, erosion, watershed.

Abstract

Potato is a prime horticultural commodities for Kerinci District with production centers in the volcanic highlands of Kerinci Mount, Jambi Province. Less of physical and chemical properties of the soil, excessive fertilizers and pesticides chemical were caused potato low productivity anddeclined soil quality. The objectives of this research were to determine the potato agrotechnology that can improve soil quality and potato productivity in the Sub District of Kayu Aro, Kerinci District, Jambi Province. Potato agrotechnology were studied through small of experimental plots in Gunung Labu Village by a randomized block design with 13 treatments (agro-potato : ridges across the slope, a quality seeds, dose of lime, manure and chemical fertilizers according to the recommendations provided). Data collected include before and after of treatment of soil properties and productivity of potato. Results of the research showed that planting potatoes in ridges across the slope with 0.5 tons of Dolomite lime, 10.0 tons of manure, 150.0 kg of Urea, 150.0 kg of ZA, 25.00 kg of SP-36 and 20.00 kg KCl per hectare were sufficient to obtain optimal productivity of potato (39.52-37.0 kg/plot, equivalent 32.93-30.91 t/ha) and improved soil chemical properties of Andisol Gunung Labu Village (especially pH, base saturation and exchangeable bases) in the Western Sub District of Kayu Aro, Kerinci District .Key Words: Soil quality, agrotechnology
