The study aimed at determination of the effect of intercropping maize and beans on the maize yields Isingiro Town Council, Isingiro District, South Western Uganda. The study used a randomized complete block (RCBD) experiment in which 8 treatments in 4 replicas of each to make a total of 32 sub-plots. Two rows of maize spaced at 4.5cm within rows and 90cm between rows were intercropped with two rows of velvet beans spaced at 30cm with rows and 90cm between rows. Two rows of NABE16 spaced at 4.5cm within rows and 75cm between rows were intercropped with maize a pacing of 5.5cm within rows and 75cm between rows. Rows of beans were separated from those of maize by 75cm in a 10m by 8m sub-plot. The experiment was conducted in two seasons (March to May 2020 and August to November 2021). Standard agronomical practices were followed from planting to harvesting, after which dry maize grain weight was taken and recorded. Data analysis was done using ONE WAY ANOVA in STATA version 13. Results show that the significant statistical difference in season one (p = 0.0000)** was higher than that in season two (p = 0.0211)*. The study concluded that unpredictable (too much or too little) rainfall negatively affects maize productivity. Early planting and application of organic fertilizers were recommended to improve maize productivity.
** The paper is based on the study carried out by the author for FAO (Food and Agriculture Organization) and FANRPAN (Food, Agriculture and Natural Resources Policy Analysis Network) as a consultant. Based on the projection on population growth and food consumption pattern in developing countries, there is likely to be a deficit in the food production by the year 2050. Africa’s population has just passed 1 billion and it is expected to double by the year 2050 (FAO 2012) According to FAO, Sub Saharan Africa, Uganda inclusive, is the region that has the highest proportion of poor and undernourished people in Africa (FAO,2011a). Agricultural production will, therefore have to increase by at least 70% in order to ensure that the food demands are met. Meeting the food demands of a growing population is already a formidable task for agricultural sector of many developing nations like Uganda but this will be further exacerbated by climate change. Largely due to climate change, agricultural productivity is likely to decrease. Similarly, the stability of production and incomes are likely to change. This trend may be even worse in countries which are already experiencing food insecurity (FAO 2012) The important implication of this is that for Uganda, policy makers will be faced with an even greater challenge to ensure that agriculture contributes more in addressing food security issues, development and climate change (adaptation and mitigation). In other words, agriculture in Uganda must undergo major and significant transformation in order to address the challenges likely to be faced in achieving food security and responding to climate change. Put in another way, in order to stabilize output and income, production systems must become more resilient or more capable of performing well in the face of disruptive events. This requires transformation in the management of natural resources and higher efficiency in the use of these resources and inputs for production. According to FAO, approaches that seek to maximize the benefits and minimize the trade-offs across the multiple objectives, often associated with agricultural sector, require more integrated and coordinated planning, policies and institutional arrangements as well as financing and investments. Such approaches and related enabling requirements are referred to by FAO as climate smart agriculture. Climate Smart Agriculture (CSA) is thus a way to ensure the achievements of future food security under climate change. CSA encompasses sustainable agriculture and it includes the need for adaptation and the potential for mitigation with associated technical, policy and financing implications. This scoping study attempts to review and examine the current production practices as it relates to CSA in Uganda. The study also seeks to conduct comprehensive reviews of the existing policies, analyze gaps and identify relevant policy recommendations.
