Abstract

Field experiments had been carried out to study the effect of 10 years alley cropping system on surface run off and soil erosion. Experiments were carried out on Alfisols at Jatikerto, Malang and on Vertisols at Ngrimbi, Jombang, East Java. The results showed that after 10 years planting tree crops and or grass as hedgerow in between food crops very efeective to decrease surface run off and soil erosion. After 10 years of planting the tree crops, the alley cropping system could decrease surface run off and soil erosion more than 40% (compared to that of the non alley cropping system) At the same time, soil erosion decrease up to 60% of the non alley treatment. The use grass as hedgerow crops yielded a better result, in term of surface run off and soil erosion. A comparison between tree species, Flemingia and Gliricidia are better than Leucaena

Abstract

An effort on improving value of orchid export trade offs either qualitatively or quantitatively needs sufficient orchid culture, beginning from acclimatization. The purpose of the study was to find out responses on various culture media toward the success of acclimatization of Dendrobium Hybrid resulted in appropriate media. This research used a randomly completely block design consisting of three treatments, i.e. broken bricks + edible fern, broken bricks + fresh coconut fibre, and broken bricks + coconut fibre compost. Every treatment was replicated nine times. The observed parameters included the beginning of new sprout of leaf, the amount of increasing leaves, the length of leaves and the width of leaves. The results showed that the treatment toward various media cultures affected all the parameters observed. A medium of broken bricks + fresh coconut fibre was the most appropriate media to acclimate orchid Dendrobium hybrid. The readily growth of bud was around 27,5 days, the highest development of leaves was around 1,81 days, the longest growth of leaves was approximately 5,08 cm and the widest growth of leaves was about 0,94 cm after 10 weeks acclimatization

Abstract

A study that was aimed to elucidate cost, revenue, profit and feasibility of farming local and high yield rice varieties, production factors affecting production of local and high yield rice varieties, and efficiency of production factors and return to scale of rice farming was conducted at Bambulung Village, Pematang Karau District of Barito Timur Regency. All rice farmers at the village was divided into two groups, i.e. farmers using local variety and farmers using high yielding variety of IR66. Production factors analyzed were land, labour, seed, urea fertilizer, SP36 fertilizer, KCl fertilizer and pesticide. Results showed that farming either local or high yielding rice varietis was profitable and feasible to be carried out. Profit made by farming high yielding rice variety was 36% greater than that of local variety. For high yielding variety, variation of production factors contributed 69,1% to variation of rice production, while variation of production factor for local variety contributed 81,8% to variation of rice production. Dominant production factors affecting production of high yielding rive variety were land and urea fertilizer, while those of local variety were land, labour and seed. All production factors of farming high yielding rice variety were not sufficiently applied and needed to be increased to achieve an efficient production level. Similarly for local variety except that SP36 that was already excessively used and need to be reduced to achieved an efficient production level. Production process of either local or high yielding rice variety farming was at increasing return to scale
