GROWTH RESPONSE AND PRODUCTION OF ONION BY APPLYING ORGANIC FERTILIZER FROM INDUSTRIAL WASTE AND ANIMAL WASTE

Organic fertilizer is one of the factors that can affect the growth and yield of onion. This research aimed to
evaluate the response of growth and yield of onion lowland through organic fertilizers from industrial waste and
livestock waste. The experiment was conducted in June to September 2014 at greenhouses Institute for
Agricultural Technology Bengkulu. Experiments using a randomized block design with a single factor, it was use
of organic fertilizers of various kinds of agricultural waste that is solid (P1), composted of cow manure (P2),
quail manure (P3) and control (P0) which is repeated five times. Data were analyzed by analysis of variance and
tested further by DMRT to determine differences between treatments. The results showed that the organic
fertilizer significantly affected the growth and yield of onion. Of a given type of organic fertilizer, cow manure
compost produced the highest yield (44.63 cm) in height parameter plant age 45 days after planting, weight of
wet biomass (124.03 g), gross dry weight (79.54 g) and number cloves per clump (24.27 cloves) while the net dry
weight was not significantly different, but the provision of manure cow compost generates the highest net dry
weight (72.08 g).
