Abstract
Potato (Solanum tuberosum L.) is one of the most important crops globally. There is little information on balanced use of chemical fertilizer on potato production in Benchi-Maji Zone. Thus, a field experiment was conducted with the objective to investigate the effect of NPS fertilizer rate on the growth parameters of potato. The treatment consisted of four levels of NPS fertilizer (0, 50, 100 and 150 kg ha-1) which were laid out in RCBD with three replications. Improved potato variety "Gudene" was used as a test crop. NPS fertilizer rate had significantly influenced almost all the tested parameters of potato. Day’s to 50% flowering was highly significantly affected by NPS rate. Early day to flower were obtained with the application of 100 kg ha-1 of NPS fertilizer and late flowering recorded at 150 kg ha-1 NPS fertilizer application rate. Significantly highest plant height of potato was obtained from application of 150 kg ha-1 NPS fertilizer and the smallest height is obtained from application of 50 kg ha-1 NPS fertilizer.

Abstract
Adoption of banana tissue culture in Uganda still remains low despite the availability of policies geared to enhancing agriculture. A survey was carried out on 115 smallholder farmers in Central Uganda to establish the influence of agro-related policies in tissue culture banana adoption between January and July 2018. Results from the study indicated that 83.8% of the respondents were aware about the Plan for Modernization of Agriculture policy as compared to National Agricultural Policy (5.5%), National Development Plan (13.12%) and Agricultural Sector Development Strategy and Investment Plan (3.3%). Age, gender and education level all exhibited weak correlations in relation to policy awareness while generally, the study found out that awareness of the of the policies did not significantly influence farmer’s adoption of tissue culture banana in central Uganda (P>0.05). We conclude that most of the agro-related polices were on paper and minimal efforts were in place to enhance their awareness amongst small holder farmers. We therefore recommend that increased awareness of agro-related policies to the farmers as well as integration of farmer interests in policy formulation are paramount in order to achieve wide uptake of agro-technologies like banana tissue culture.
