Abstract

The using of synthetic pesticide in control of crop pest cause various of negative impacts like resistance, resurgence, the incidence of secondary pets, killing of the natural enemy and is impure of environmental even death to human being and animal. One of the correct operation alternative to decrease the using of synthetic pesticide is biological control with exploiting of entomopathogen caiied Beauveria bassiana. This Entomopatogen has an ability for infection of insect either through direct contact, and also inoculation of woof was given to target insect by producing the toxin so that insect body closed conidia and become hard like a mummy. The ability is also influenced by the condition of environment especially temperature and dampness. B. bassiana has high patogenistas ability almost in all of the insect. B.bassiana can depress the population of coffee powder H. hampei of Helopeltis spp equal to 76% and the other insect type. Application of B. bassiana don't generate death at another pest which good for (natural enemy) in nature. Infection mushroom mechanism of entomopathogenic B. bassiana in control of pest in the field happened by direct contact, inoculation and also contamination with target pest insect and effective in controlling of various pest insect type. Its effectiveness is influenced by a variety of isolate types, the closeness of spore, quality of media grow, controlled pest type, age of stadia pest, application time, application frequency and environmental factor.

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 %.

Abstract

One of the leading plantation commodities in Indonesia is cocoa (Theobroma Cacao). Through the Decree of the Minister of Agriculture and Plantation (Kepmentan) No.46 / Kpts / PD.300 / 2015 Ende Regency, East Nusa Tenggara [NTT] was determined as a mainstay cocoa plantation area, but in fact, the production was not optimal. Based on these considerations, this study aims to determine the level of cocoa farming income and the factors that influence farmers' income and analyze the feasibility and usefulness of a cocoa farming fund. The method used in this research is the descriptive method. The research location was determined by purposive sampling, based on the consideration that the area is a cocoa-producing region in Ende Regency. Sampling is the Ende Selatan District of Kedebodu and Rewarangga Villages. The population is all cocoa farmers, with a sample of 20 respondents. Data were collected by interview, questionnaire, observation, and documentation techniques. The feasibility analysis is done by the B / C ratio analysis. In addition to the analysis also conducted an analysis of income and receipts with the formula TC and TR. The results showed a B / C ratio of 5.24% which meant that the cocoa business was profitable and feasible to be developed. Total income from cocoa and non-cocoa is Rp 315,732,000. and from cocoa alone. Rp 91,532,000, - and total revenue of Rp. 73,897,000, and non-cocoa Rp. 29,933,000. While the total cost of cocoa is IDR 17,635,000 and non-cocoa IDR 194,267,000. Factors influencing the cocoa business in Ende District include level of education, gender participation, labor age, age of old cocoa plants, and not yet applying profitable technology. It is advisable for farmers to intensify cocoa farming by implementing P3S, and post-harvest processing, forming young people groups and building networks of cooperation with all stakeholders.

Abstract

This study aims to determine the application dose of liquid organic fertilizer from black rice wastewater on the growth and yield of mustard greens. The research was carried out at the Experimental Garden of the Faculty of Agriculture, the University of Flores for 6 months from June to November. The research was carried out using a randomized block design consisting of 6 doses of black rice liquid waste (Liquid Organic Fertilizer: LOF), namely: P0 = without LOF, P1 = 2,400 ltr/ha = 750 ml/plot; P2: 4800 ltr/ha = 1500 ml/plot; P3: 7200 ltr/ha = 2250 ml/plot; P4: 9600 ltr/ha = 3000 ml/plot; P5: 1200 ltr/ha = 3750 ml/plot; which was repeated 4 times, so there were 24 experimental experiments. The application of liquid organic fertilizer from black rice liquid waste to mustard greens showed an average response to an increase in plant height of 5.08%, leaf number of 7.95% and leaf area of 17.59%. The yield uptake variable was 11.51%, and the application dose of 9600 ltr/ha gave a plant height of 46.41 cm, a number of leaves 8.25, leaf area 1691.35 cm2, and fresh weight of mustard greens tan-1 of 153.65 and the weight of mustard ha-1 was 24.58 tonnes, but not significantly different from P3 (7200 ltr/ha).
