| dc.description.abstract | The study aimed to: (i) formulate a 3 in 1 pelleted natural fertilizer (PNF), (ii) evaluate the efficacy of the formulated PNF as soil organic matter enhancer, nutrient source and in reducing golden apple snail infestation in lowland transplanted rice, and (iii) assess economic benefit through partial budget analysis of its use in lowland transplanted rice production. The experiment was laid out in Randomized Complete Block Design (RCBD) with eight (8) treatments and three replications. The recommended Rate of Inorganic Fertilizer (RRIF) is 100-60-60 N, P2O5, K2O/ha while 2 t/ha PNF rate was used. The rice variety used was NSIC Rc 216also known as Tubigan 17. A 3-in-1 PNF was formulated using ordinary compost molasses, organic foliar fertilizer and tobacco leaf extract. it has 0.90% N, 3.53% P2O5, 1.36% K2O and a pH of 7.83. Pure application of 2 t/ha PNF did not improve growth and yield performance of lowland transplanted rice. Furthermore, when applied in combination with full RRIF and half RRIF, no significant increase in yield over the full RRIF was noted. These treatments however (RRIF + 2 t/ha PNF) increased grain yield over the control with 6.12 t/ha and 3.72 t/ha , respectively. Partial budget analysis showed that only T7 (RRIF + 2 t/ha PNF) and T8 (farmer's practice) had a positive net benefit of Php 1,553.00 and Php 12,145.00 respectively, with RRIF as the basis. It is recommended that further study be done using higher rates of application of PNF with 2 t/ha as the reference rate. | |
