Kajian Beberapa Jenis Pupuk dan Pestisida Organik Terhadap Pertumbuhan dan Hasil Tanaman Sawi di DKI Jakarta
Abstract: 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.
