Field Performance and Profitability of Bingawan Black Rice (Oryza sativa L.) Grown Under Various Production Systems

Abstract

The growing trend towards healthy lifestyle among consumers led to the production of nutritious and organic staples. Black rice (Oryza sativa L. Bingawan cultivar) is known to be both. While most studies on rice are conducted through conventional approach, this experiment aimed to assess the response of black rice to various organic production systems on productivity and marginal analysis. A Randomized Complete Block Design (RCBD) was used with 4 replications and 3 treatments; T = UPLB's best bet organic production system, T = optimized organic 1 2 production system in Leyte, and T = conventional production system in Leyte. 3 Leyte's optimized organic production system (T ) promoted the heading and 2 maturity of black rice comparable to the conventional production system in Leyte (T ). The UPLB's best bet organic production system (T ) produced heavier fresh 3 1 straw yield and total biomass, more productive tillers, filled and unfilled grains per panicle, heavier grains per hill, and high grain yield. However, it generated a lower net margin than the conventional production system in Leyte (T ). When sold 3 unmilled, black rice has comparable net margins irrespective of the production systems. The markedly higher yield in T failed to compensate for the higher 1 production cost, resulting in a lower net margin. It is worth noting, however, that organic rice commands a relatively higher prevailing price, unmilled and milled, than those produced in the conventional system.
