PERFORMANCE OF MODIFIED DAPOG USING DIFFERENT ORGANIC INPUTS FOR RICE SEEDLING PRODUCTION

Ellen S. Romero and Jonathan E. Ramos

Abstract

The research which was conducted in four cropping seasons in a certified organic farm aimed to determine the performance of modified organic dapog as an efficient method for organic rice seedling production. The modified organic dapog is a method of organic rice seedling production with advantages of lesser planting space, lower labor cost in pulling and easier transport of seedlings from seed bed to rice paddy. It also produces less roots and stem damage seedlings because the seedlings do not penetrate deep in the soil. Using mixture different forms of organic fertilizers like vermicast, organic liquid supplement and microbials were proven effective in improving soil quality thus enhancing the growth of rice seedlings.

Two studies were conducted namely; wet bed method for organic rice seedling production using NSIC Rc 222 variety; and yield performance trial using the seedlings produced, both for modified organic dapog method and traditional dapog method.

The seedlings produced using modified organic dapog method has the tallest plant and longest root as compared to traditional method and control. It was likewise observed that shoots and leaves of seedlings from modified organic dapog method were vigorous and greener as compared to the other treatments evaluated.

In terms of grain yield plant from modified organic dapog method obtained the highest computed grain yield of 5.313 t/ha or 18.25% higher than traditional dapog method (T2) and 22.39% higher than the control (T1).
