Response growth and yield of okra (Abelmoschus esculentus l.) to giving dosage levels of chicken manure and variation of plants spacing

Abstract

This research was aimed to the response of dosage of chicken manure and variation of plants spacing on the growth and yield of Okra (Abelmoschus esculentus L.). This research was conducted from December 2018 until March 2019 in the Experimental Garden of Indonesia Vegetables Research Institute, Situ Gadung, Tangerang, Banten. This research used a Randomized Completely Block Design (RCBD) with two factors, the first factor was a dosage of chicken manure consisting of three levels P1 (25 ton/ha), P2 (30 ton/ha), and P3 (35 ton/ha) and the second factor was variation of plants spacing consisting of three levels J1 (40 cm x 50 cm), J2 (50 cm x 50 cm), and J3 (60 cm x 50 cm). The results showed that treatment of 35 ton/ha chicken manure (P3) had the best effect at plant height (24.89 cm) and number of leaves (7.59 leaf) on 30 days after planting, number of flowers (10.48 flowers) and number of fruits per plant (10.00 fruits) on 80 days after planting, number of fruits per plot (154.44 fruits) and mass of fruits per plot (4.02 ton/ha) on 90 days after planting, and mass of fruits per plant (4.64 ton/ha) on 100 days after planting. The variation of plants spacing had the best effect to number of fruits per plot (114.67 fruits) on 80 days after planting and mass of fruits per plot (1.9 ton/ha) on 70 days after planting. There was interaction between dosage of chicken manure and variation of plants spacing at number of leaves on 30 days after planting, number of flowers on 70, 80, and 100 days after planting, number of fruits per plant on 50, 70, 80, and 100 days after planting, number of fruits per plot on 50, 60, 70, 80, and 90 days after planting.
