A rice-greengram cropping system increases on-farm yields of rice developed and tested by NARO with support from WOUGNET and Makerere University. The activities involved include;
Activity 1: Participatory selection of rice and greengram varieties. Farmer groups are identified and trained to participate in evaluation and selection of the most suitable varieties of both crops best on local context.
Activity 2: Participatory evaluation of rice-greengram rotational cropping. Farmer groups are identified and trained to participate in evaluation of rice-greengram rotation cultivation. As a rotation crop, greengram is used in three ways – as first crop preceding rice, as furrow crop after harvesting rice, and as green manure. Three host farmers per site evaluate the impact of greengram in the different ways. Soils of selected trial fields are sampled and analyzed prior to and after the experiments. The experiments are conducted in two seasons starting in the second half of the first year.
Activity 3: Participatory evaluation of integrated soils fertility management approach. Three farmer groups per project site are identified and trained to evaluate the effect of micro- dozing of phosphorus (P) and Potassium (K), and rhizobia inoculation, a biological fertilizer. One group evaluate micro-dosing of P and K, another rhizobia inoculation and the third a combination of the two. Soils of selected fields will be sampled and analyzed before and after the experiments. Evaluation trials will be conducted for two seasons starting in the project’s second half of the first year.
