RESPONSE OF OKRA (Abelmoschus esculentus) TO VARYING RATES OF RICE HULL ASH IN CLAY-LOAM SOIL

The study was conducted at Mindanao State University-General Santos City, Prof. Mansueto Cuaton Research Area, from September 2018 to December 2018. This is to evaluate the response okra (Abelmoschus esculentus) to varying rates of rice hull ash in clay-loam soil. This study used a Randomized Complete Block Design (RCBD) with four (4) treatments and replicated three (3) times. The treatments were as follows: T1 -Control (pure clay-loam soil), T2- Tripple 14-14-14 (pure clay-loam soil), T3-500 kg RHA/ha + 60kg N, T4-1 ton RHA/ha + 60 kg N. The results indicated that plant height, number of pods, pod weight and pod yield (t/ha) were highly significant at 1% level. The highest result was observed in T4-1 (1 ton RHA/ha + 60kg N), followed by T3-(500 kg RHA/ha + 60kg N) over the T1- Control (clay-loam soil) respectively. Hence, the application of Rice hull ash (RHA) can best used for acidic and clay-loam soils, and can help to increase crop production and waste management of Rice hull.
