Soybean is one of the crops that produce seeds with high protein content, as well as used by the inhabitants of Indonesia. Domestic soybean production can not meet the needs of the national soybean thus needs to be improved, one through breeding varieties with superior. One important step in plant breeding is the selection. To save time and costs of selection, it is necessary to determine the estimated correlation between characters and to determine the causal relationship between characters used path analysis. Through path analysis can be seen directly and indirectly influence between variables forecaster with the response variable. The purpose of this study to obtain information (1) correlation between characters agronomic towards production. (2) direct and indirect effects of agronomic between characters towards production. The research was conducted from October 2013 until January 2014 in the integrated field laboratory of the Faculty of Agriculture, University of Lampung and observations made in Laboratory of Seed and Plant Breeding, University of Lampung. Soybean seeds used were F5 generation zuriat from Wilis x Mlg 2521, Willis and Mlg 2521. The treatment laid out in a randomized block design, 2 replications. The results showed that there was a positive phenotype correlation between character of days to flowering, plant height, number of branches, number of pods, weight of 100 grains with grain weight per plant and there was no correlation between day to harvesting with the seed weight per plant. Direct selection of the most effective was through the number of pods because number of pods have a direct effect almost equivalent to the correlation. The relationship between the number of pods and weight of seeds per plant explained a real relationship. Keywords: correlation, path analysis, selection, soybean

The problem to increase of crops productivity are the scarcity and high price of fertilizer. As a result, farmers do not apply fertilizer technology optimally. The use of agricultural waste by implementing waste treatment technology is helping farmers to substitute chemical fertilizers with organic fertilizers. The study was conducted in Agam district that could potentially apply agricultural waste treatment technology. Study done in June-July 2011 with the aim of measuring the level of waste treatment technology adoption and its benefits in increasing the income of farm families. Survey research methods by taking a random sample of 15 farmers, the program PUAP (Rural Agribusiness Development) implementers on 2 Gapoktan in the two regences. Data analysis was performed using analysis of farm and comparative analysis to see the difference in income between the farm system is not applying with. The study results showed that: (i) Information on wastewater treatment technology has not spread extensively in each area gapoktan; (ii) The control of waste treatment technologies are still weak and low, as evidenced most farmers know the technology but has not been implemented due to not understand the technical implementation; ( iii) The adoption of such technologies for the processing of agricultural waste composting 25-35%, 35-40% of feed processing technology and biogas technology has not been adopted, despite the considerable potential for biogas processing. The benefit is the application of waste treatment technologies in rice cultivation has increased the average yield of 15% and to increase the yield of 20% corn. The crop yield improvement in integrated farming systems, to increase the income of farm families on average 12.90%. Suggested to the parties involved to be made: (i) science and technology capacity building of farmers and extension members Gapoktan PUAP companion, especially on waste treatment technologies for the integration of crops and livestock to be effective. (Ii) Optimization of the utilization of agricultural resources owned by farmers (land and labor) and the arrangement of the combination of commodities to the optimal integrated farming systems, need to be developed in areas of potential gapoktan. In this way the acceleration is expected to increase farmers' income can be achieved, the efficiency of production costs and dependence on mimia fertilizer can be reduced.

Until the current level of dependence on agricultural products in DKI-Jakarta from other areas increasing, estimated level of vegetable consumption / capita in urban -9.8 1.1% higher if compared to rural areas. Increased production and plant health conducted with crop rotation, intercropping, planting the right varieties, biological pest control. One of the environmentally-friendly technologies that can be used to improve the quantity and quality of the horticultural farming is very suitable for the conditions in Jakarta are the organic farming. The purpose of the study, assessing alternative technology packages organic farming leaf vegetable crops in the dry season, conducted from May to December 2008. This assessment activities carried out in Rawasari, Jakarta-Central, involving 6 farmer cooperators. As the indicator is a mustard plant. The design used was a randomized block design with 6 replications and 4 were tested technology package include: a) BPTP fertilizer (from urban waste)+Pest control with Nemasal (botanical pesticides), b) Fertilizer Dharmajaya (from beef cattle waste)+Pest control with sweeping (sweep with cloth), c) Fertilizer Pegadungan (from enceng gondok+stater)+Pest control with sweeping and d) Farmers fertilizer (chicken manure+Urea)+control OPT with Curacron/decis. The results of study of organic technology package on leaf vegetable crops (mustard) in DKI-Jakarta showed that, using fertilizer Dharmajaya (waste from the abattoir) with sweeping OPT can increase the growth and yield of mustard plants, equivalent if using fertilizer formulations BPTP (waste from urban waste + enrichmen). With the use of packet 1, it gives the highest profit, ie the B / C ratio: 3.8. While the B / C ratio is the lowest obtained in the use of packet 3, the gain B / C ratio is less than 1. It shows that, organic farming technologies provide considerable opportunities high in leaf vegetable farming, especially in the mustard plant in the dry season.
