- Effect of Split Supplement Foliar Phosphorous Application on Growth and Yield of Potato (Solanum Tuberosum)
- Abstract
- Supplement foliar phosphorus is needed in potato production to maximize the final yields. Whilst supplement foliar phosphorus is important in potato production, it is not quite clear on how it can be applied. The field experiment was carried out to investigate the effectiveness of split application of supplement foliar phosphorus on growth and yield of potato. All treatments were supplied with potato blend (8:24:20) as a basal fertilizer. For split application, supplement foliar phosphorus was applied soon after full emergence using a rate of 5l/hectare, and this was repeated 4 more times at an interval of 7 days using the same rate. For single application, supplement foliar phosphorus was applied once soon after full emergence using a rate of 25l/hectare. No supplement foliar phosphorus was applied in a control treatment. These 3 treatments were replicated 3 times in a randomized complete block design. Data collected on growth and yield parameters were subjected to analysis of variance (ANOVA) using GENSTAT 2016 edition and an LSD (p=0.05) was used to differentiate between statistically different means. Split application of supplement foliar phosphorus showed highest significant p<0.05 results on growth parameters (leaf area, leaf number, plant height and days to flowering). It also shows highest significant p<0.05 results on yield parameters (tuber number and tuber weight). The findings suggests that split application is the best when applying supplement foliar P. with the same amount of foliar fertilizer, a farmer can increase potato yields by using split application method than single application
