Growth and yield performance of upland rice (Oryza sativa L. var. zambales) intercropped with mungbean (Vigna radiata L.) and peanut (Arachis hypogaea L.)

One way of increasing productivity per unit area per unit time is through intercropping. This study aimed to evaluate the growth and yield performance of upland rice intercropped with mungbean and peanut, determine the appropriate intercrop that would give optimum yield of upland rice, and assess the profitability of upland rice production intercropped with mungbean and peanut. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The treatments were designated as follows: T0 = monoculture upland rice, T1 = Upland rice + Mungbean var. Lg Mg 28–6–0, T2 = Upland rice + Mungbean var. Pag–asa 7, T3 = Upland rice + Peanut var. CVRC Pn 2011–002, and T4 = Upland rice + Peanut var. Pn 06–34–3a. Results showed that intercropping upland rice var. Zambales with mungbean and peanut significantly affected the number of days from sowing to heading, days from sowing to maturity, leaf area index, fresh straw yield (t ha-1), number of unfilled grains per panicle, and weight of grains per 0.50 linear meter. Monoculture upland rice (T0) matured earlier and had the highest leaf area index and straw yield. Upland rice with peanut var. CVRC Pn 2011–002 (T3) had more unfilled grains and higher weight of grains per 0.50 square meter, while upland rice with peanut var. CVRC Pn 2011–002 (T4) had the highest LER value of 1.30 and ATER value of 1.93. Highest rice grain yield of 2.8 t ha-1 and highest gross margin of PhP 106,757.02 ha-1 were obtained from upland rice with peanut var. CVRC Pn 2011–002 (T4), while lowest gross margin of PhP 13,727.14 ha-1 was obtained from the upland rice monoculture (T0).
