Abstract

The major practice was conducted at Block-12, Pili Drive of University of the Philippines (UPLB) Central Experiment Station (CES) from June 2015?May2016 to document and assess three upland rice-based crop rotation patterns: 1) upland rice-upland rice 2) upland rice-green corn and 3) upland rice-mungbean. Cultural management practices were documented in the three cropping patterns. Multiple cropping indices such as Multiple Cropping Index (MCI), Land Equivalent Ratio (LER) and Crop Equivalent Yield (CEY) showed that the three cropping patterns were advantageous than the conventional rice-fallow system. Among the three upland rice-based cropping patterns, rice-mungbean had the highest LER of 2.12, which meant that an area planted as a pure stand would require 1.12 more land to produce the same yield with the same area planted for a rice-mungbean. This followed by rice-green corn pattern with an LER of 1.86 and rice-rice cropping pattern with LER of 1.47. For CEY, rice-green corn cropping pattern had the highest value of 14.86 followed by rice-mungbean with a value of 9.86 and then rice-rice with 4.28 CEY value. This meant that the yield equivalent of rice in a rice-green corn cropping pattern was 14.86. The results showed that by planting other crops like green corn instead of rice after rice would give higher equivalent yield. In economic terms, the most profitable cropping pattern was rice-green corn with a net farm income of PhP3,931.85 with a positive return of investment (ROI) of 0.18. Rice-mungbean cropping pattern incurred loss from farm operations of about PhP5,406.85 with a negative ROI of 0.25. Meanwhile, rice-rice cropping pattern incurred the highest loss among the three cropping patterns, about PhP13,379.40 with a negative ROI of 0.65. Negative ROIs of rice-rice and rice-mungbean cropping patterns were due to operational costs (irrigation due to the presence of El Niño, hiring of bird watchers and high costs of fertilizers) that outweighed returns. Given the values of multiple cropping indices (MCI, LER and CEY), it was clear that the recommended cropping pattern for the study was rice-green corn. In terms of profits, rice-green corn also had the highest income with a positive ROI as well. But before adapting this cropping pattern, other factors should be considered such as availability of market and time of selling of the produce. The two cropping patterns, rice-rice and rice-mungbean, however also had positive values of multiple cropping indices but when subjected to profitability analysis, both patterns incurred losses. Nevertheless, these two cropping patterns are still recommended in upland areas provided that alternative solutions to the problems identified in the study will be complied.
