Effects of Kappaphycus Drippings (KD) Foliar Fertilizer on the Growth and Yield Performance of Rice (Oryza sativa)

Rice (Oryza sativa) is a vital staple food crop in more than 60 percent of the world, and around 430 million metric tons rice are consumed worldwide. Moreover, to reduce synthetic fertilizer use while keeping production on track, researchers decided conduct study Kappaphycus drippings (K.D.) foliar at Brgy. Mangayon, Compostela, Davao de Oro from July December 2019 determine effects different rates (S.F.) supplemented with growth yield performance return cost (RPC). Randomized Complete Block Design (RCBD) was used experiment, six treatments replicated four times. The were as follows T1 - 100% SF (Control), T2 90% + KD, T3 80% T4 70% T5 60% KD T6 50% KD. experimental plot has 4 x 4-meter dimension. results showed that K.D. positively impacted plants' performance, particularly plant height, leaf color index (LCI), number tillers productive per hill and, same time, reduced bug population. Furthermore, influenced by increased despite lesser (S.F.).
