Influence of Timing of Planting on the Growth and Yield Performance of Upland Rice (Oryza sativa L. var. Zambales) and Peanut (Arachis hypogaea L.) Intercrop
Abstract
Intercropping is one way of increasing productivity per unit area per unit time. This study aimed to 1) evaluate the effects of timing of planting on the growth and yield of upland rice and Peanut under the intercropping scheme; 2) determine the appropriate timing of planting upland rice and Peanut that would give optimum yield, and 3) assess the profitability of upland rice and peanut production under the intercropping scheme as influenced by the timing of planting. The experimental area was laid out in a Randomized Complete Block Design (RCBD) with three replications. The treatments were as follows: T1 - upland rice + Peanut planted simultaneously, T2 - Upland rice planted one (1) week ahead than Peanut, T3 - Upland rice planted two (2) weeks ahead than Peanut, T4 - Peanut planted one (1) week ahead than upland rice, and T5 - Peanut planted two (2) weeks ahead than upland rice. Results showed that upland rice planted two (2) weeks ahead of Peanut (T3) and those planted simultaneously with Peanut (T1) headed and matured earlier than the other treatments. Likewise, T3 and T5 obtained the heaviest panicles per 0.50 linear meter. Similarly, peanut var. BPI-Pn9 planted two weeks ahead of upland rice (T5) flowered and matured earlier than the other treatments. The highest LER and ATER values of 1.50 and 2.02, respectively, were obtained from T5 (Peanut planted two (2) weeks ahead than upland rice). The highest combined yield of upland rice (2.42t ha-1) and Peanut (1.47t ha-1) was also obtained from T5, which resulted in the highest gross margin of PhP86,867.02 ha-1.
