Abstract:
The use of liquid organic fertilizer (LOF) has been increasingly practice to improve the
effectiveness of solid organic fertilizer application in the production of many vegetable crops.
Proper selection of green biomass must be taken into account since type of green mass
determines the nutrient contents in LOF. Water hyacinth is a green biomass that widely grows
water ecosystem around the vegetable growing area and is considered as a promising source of
biomass for LOF production. This experiment aimed to determine the optimum concentration of
water hyacinth-based LOF for growth and yields of cucumber. A complete randomized design
experiment was established with three replicates. Treatments consisted of 0 %, 20 %, 40 %, 60
%, 80 % and 100 % concentrations of water hyacinth-based-LOF. Results indicated that the use
of water hyacinth LOF significantly increased leaf number, shoot fresh weight and shoot dry
weight. In addition, the use of water hyacinth LOF also significantly increased fruit diameter,
fruit length, fruit weight and fruit hardness of cucumbers. The application of 100 % of water
hyacinth LOF was the best concentration to increase cucumber growths and yields |
