Agrica: Journal of Sustainable Dryland Agriculture is a journal that presents a platform for sharing knowledge in science and technology related to Sustainable Dryland Agriculture. Its studies are agronomy, pest and plant diseases, soil science, agricultural conservation and ecology, organic farming, agrobiodiversity, agrotourism, permaculture covering the economic aspects of dryland sustainable agricul¬ture (agribusiness, agricultural socio-economic,, agroindustry), agricultural diversification, land and water conservation, agricultural climate, food security, animal welfare concept, mechanization, science and food technology in a dryland environment.

Abstract

The objective of the research was to determine the respiration rate of vegetable through calculating CO, content resulted from the respiration process. The nature of the research was experimental research which held in a laboratory at the Faculty of Agriculture, Flores University. The result showed that respiration process released C02 and energy. Titration result in yam showed higher C02 content in comparison to cabbage and mustard green. However, the respiration rate of mustard green was higher than other vegetables. The logic behind the results was that the position and the number of stomata per area of the leaf determine respiration rate. In this case, the number of stomata on the mustard green was higher than other observed vegetables. In fact, the respiration rate of vegetables is determined by several factors. Specifically, some internal and external factors affect it, such as soluble matters availability, oxygen, temperature, type and development stage of plants. Morphologically, certain vegetables produce more moisture content than others, which is, in turn, produce low respiration rate.

Abstract

An intensive agriculture activity, especially that done on dry land, will result in a decrease in productivity. The land will get easily eroted, slopy, sour and poor in nutrition. Sustainable agricultural development needs technologies of conservation of land and water. One of such technologies is the technology of vegetation conservation. This refers to the planting of trees, bush, grass or land covering crops. The planting of land covering crops functions to: 1) minimize erosion; 2) minimize the growth of weeds; 3) change the microclimate and the land temperature; 4) to make sources of livestock food available; 5) increase the land organism; 6) improve the physical and chemical nature of the land. The findings of some researches show that the land covering crops can minimize the speed of erosion 40 %, increase the land fertility by 30 % and minimize the growth of weeds by 50 %.
