Abstract
Abstract Ultisols has constraints in low organic matter, low pH, low CEC, and low soil nutrients. This study aimed to determine the effect of applying a combination of Organonitrofos and inorganic fertilizers on soil chemical properties and yields of cucumber plants in Ultisols. The study consisted of 11 combinations of Organonitrofos and inorganic fertilizers with 3 replications arranged in a randomized block design. A recommended dose of 100% Organonitrofos fertilizer which was 10,000 kg ha −1 and 100% NPK inorganic fertilizer (Urea = 448 kg ha −1 ; SP-36 = 413.5 kg ha −1 ; KCl = 63.3 kg ha −1 ) were applied. The treatments were various combinations of Organonitrofos and inorganic fertilizers of 0, 25, 50, 75 and 100% from each fertilizer recommendation. The application of a combined Organonitrofos and inorganic fertilizers increased pH and soil available-P, but it did not affect the total-N and organic-C of soil. All combined doses of Organonitrofos and inorganic fertilizer significantly increased all the growth and yields variables of cucumber compared to control (without fertilizer) and application of Organonitrofos fertilizer only. Application of 100% Organonitrofos + 50% NPK was the most economically effective dose because it had the highest RAE value of 101%.
