In this study, we established changes in minimum and maximum temperature over the past 20 years, and how these changes a r e likely to affect the status of key banana pests and black Sigatoka disease in main banana cropping systems. A survey was conducted at elevations of 1200, 1400, 1600 and 1800 m above sea level in 13 sites previously used in 1 9 9 2 / 1993. Mean monthly minimum and maximum temperatures at different elevations were computed between 1991 and 2013 and used to determine the temperature change. Data was collected on weevil damage, nematode populations and black Sigatoka severity. Changes in weevil damage, nematode population densities and black Sigatoka severity were determined. Pearson's correlation analysis was used to establish relationship between minimum and maximum temperature change, changes in weevil damage, black Sigatoka severity and nematode population densities at different elevations. Results show that minimum temperatures in sites above 1400 masl increased by 1°C over the 20 years. Key banana pests and black Sigatoka disease were observed at elevations where they had not occurred before. Change in black Sigatoka disease, Rhadopholus similis, Helicotylenchus multicinctus and Meloidogyne spp. positively correlated with change in both temperature but change in banana weevil's damages positively correlated with maximum temperature.

Savings mobilization is important for rural households in Uganda. This study looked at household net savings deposits in Savings and credit cooperatives (SACCO's) from individual's passbooks. Net savings were then measured as the difference between deposits and withdrawals. Weighted least squares were used to determine the factors influencing net deposits. Results indicate that deposits decreased with increase in distance to the SACCO, education levels, wealth, trade activities, and having secondary school dependants. Deposits increased with income, access to credit. SACCO's are well suited for poor households in terms of products and services offered. There was a higher propensity to save out of transitory income.

Banana is an important source of food and income for millions of people in sub-Saharan Africa and Uganda in particular. This makes it one of the most important food crops in the country. However, production is limited by both biotic and abiotic constraints. Among the biotic constraints, is the decline in soil fertility. In addressing some of these biotic and abiotic constraints, banana breeding programmes are developing and releasing new banana varieties with limited information of their efficiency to capture soil nutrients. This study was to establish the physiological nutrient use efficiency of three new banana varieties namely FHIA17, M9 and M2 at harvesting time. The study was carried out in 8 (eight) districts of Uganda. Soil and tissue samples were collected from already established banana plantations for analysis of N, P, K, Ca and Mg. Tissue samples were collected by destructive sampling. Means of nutrients within district were separated using the Least Significant Difference (LSD) test at 5% level of significance (SAS, 2008). The nutritional status of bananas and the concentrations in various organs were, with respect to N, P, K, Ca and Mg, levels subjected to ANOVA. The relationship between plant content of the five nutrients and their concentration in the soil was determined by coefficient of correlation (r). The results showed no major significant nutrient use efficiencies between cultivars with FHIA 17 having the highest nutrient use efficiency. There were a few positive correlations between soil and plant nutrients.
