Abstract


Diversification of crop cultivation is being developed in various parts of the world to complete food needs. The okra plant (Abelmoschusesculentus L.) is one of the vegetables included in it.The cultivation of these plants cannot be separated from the use of fertilizers.The combination of fertilization with chemical fertilizer and organic fertilizer is the right answer in the cultivation of these plants.For this reason, it is necessary to study the right amount of chemical fertilizer and organic fertilizer to get optimal results.This research uses factorial randomized block design (RBD) with two factors; 1. Cow manure (S) for 4 levels of treatment (a) S0 = without manure (control), (b) S1 = 1.8 kg / plot (2 tons / ha) manure, (c) S2 = 2.7 kg / plot (3 tons / ha) manure and (d) S3 = 3.6 kg / plot (4 tons / ha) manure. 2. MutiaraNPK fertilizer (P) for 3 levels of treatment, (a) P0 = without NPK fertilizer, (b) P1 = 180 grams / plot equivalent to 200 kg / ha, (c) P2 = 270 grams / plot equivalent to 300 kg /Ha.Thus there are 12 treatment combinations and each treatment combination is repeated 2 (two) times so that there are 24 experimental units.The plot of the experiment was 3 m x 3 m with a spacing of 0.7 m x 0.7 m, there were 16 green okra plants in each plot of the experiment.Observations on sample plants were carried out on 4 okra plants located in the middle of the experimental plot, which were taken at random.The results showed that the treatment of cow manure dose significantly affected the number of fruits and the weight of green okra fruit.But there was no significant effect on the height of green okra plants at the age of 15, 30 and 45 days. The best dose of cow manure is obtained at 3.6 kg/plot (4 tons/ha).The results forĀ  NPKMutiara fertilizer significantly affected the number of fruits and the weight of green okra but did not significantly affect the height of green okra plants aged 15, 30 and 45 days. The best dose is obtained at 360 grams/plot (400 kg/ha). There is no real interaction with all observed parameters.
