- Abstract
Background: Rainfed lowland rice crops are grown only once a year in the rainy season. In general, the fields are left fallowed after harvest of rice in the dry season. Cassava a drought tolerant-crop has the potential to grow the following rice. One of the methods to sustain production is through the application of beneficial microorganisms such as plant growth-promoting rhizobacteria and foliar bio-extracted fertilizer. Methods: Cassava was planted in the dry season (December-June). Nutrient management treatments included; 1) application of chemical fertilizer as recommendation rate (CFR), 2) application of CFR combined with plant growth-promoting rhizobacteria (PGPR), 3) application of 80% of CFR combined with PGPR and 4) application of CFR combined with bio-extracted pig manure (BPM) which laid out in randomized complete block design. Result: Interaction between CFR and PGPR gave the maximum storage root yield of 23.1 t ha-1 without significant differences with the application of CFR alone (20.3 t ha-1). Such treatment also provides higher net income than those of the other treatments in the present experiment.
