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.

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 correlationÂ between charactersÂ and to determine the causal relationshipÂ between charactersÂ used path analysis. ThroughÂ pathÂ analysis can be seen directly and indirectly influence between variables forecaster with the response variable. The purpose of this study to obtain information (1) correlationÂ between charactersÂ agronomic towards production. (2) direct and indirect effects of agronomicÂ between charactersÂ 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 SeedÂ and Plant Breeding, University of Lampung. Soybean seedsÂ used wereÂ F5Â generation zuriat from Wilis x Mlg 2521,Â Willis andÂ MlgÂ 2521. The treatment laid out in a randomizedÂ blockÂ design,Â Â 2 replications. The results showed thatÂ Â there was a positiveÂ 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 thereÂ wasÂ no correlation betweenÂ day toÂ harvestingÂ withÂ the seed weight per plant. Direct selection of the most effectiveÂ Â wasÂ through the number of podsÂ because number ofÂ Â pods have a direct effect almost equivalent to the correlation. The relationship between the number of podsÂ and weight of seeds per plant explained a real relationship.Â Keywords: correlation, path analysis, selection, soybean
