RESPON PERTUMBUHAN DAN HASIL OKRA(Abelmoschus esculentus L. Moench) PADA MEDIA TANAM ORGANIK DAN DOSIS BIOCHAR

Abstract

Lady finger/Okra plant is a vegetable plant that is beneficial for health and serves as a medicine. Efforts to increase okra production can be done by using organic growing media and biochar dosing. The research objectives were: To analyze the growth and yield response of okra plants due to the combination of organic growing media and biochar dosage. The research was conducted from March 2017 to July 2017 in Sekarpuro Village, Pakis District, Malang Regency. This study used a factorial randomized block design (RBD) consisting of 2 factors. Factor I: Organic planting media, consisting of 3 levels, such as: M1: planting medium sand-soil-compost litter; M2: planting media for sand-soil-manure, and M3: planting medium for sand-soil-coconut husk. Factor II: biochar dose, consisting of 3 levels: B0: Without biochar; B1 = Biochar 5 ton / ha; B2 = Biochar 7.5 tons / ha; B3 = Biochar 10 ton / ha and 1 control treatment. Observation parameters include 1) plant height (cm); 2) Number of leaves (strands); 3) The number of fruit per crop (fruit); 4) Fruit weight per plant (grams); 5) Fruit diameter (cm); 6) Fruit length (cm); 7) Bar weight (gram). Analysis of variance using ANOVA (Analysis Of Variance) and difference test with BNT 5%. The results showed that the combination of manure and biochar planting medium 7.5 tonnes / ha and coconut husk and a dose of 10 tonnes / ha biochar had a significant effect on the growth and yield of okra plants. Likewise for the number of fruit, stem weight, significantly different from the combination of growing media and biochar treatment. This is due to the fact that biochar is very effective in response to growth because the nutrient content that is quickly available is easy to absorb plants. The higher the dose of biochar given will give a high average yield. Conclusion okra plant yields because the combination of organic growing media treatment and biochar dose has a significant effect on the response to plant growth
