The objective of this study was to investigate the effect of various types of mulches on physical growth and yield of potatoes (Solanum tuberosum L.). The experiments were conducted in farmer's fields during the agricultural seasons 2022 B (Season B is from March to June) and 2023 A (Season A is from September to February). Experiment was laid out in a Randomized Complete Block Design (RCBD) in two sites with four replications and five treatments: T1 (Control), T2 (Dead mulch), T3 (Living mulch of Mucuna), T4 (Living mulch of Desmodium), and T5 (Living mulch of Lablab). Data were collected on the potato physical growth with an interval of 15 days after planting (DAP) while yield data were collected immediately after harvesting. The Analysis of Variance (ANOVA) was done in Microsoft Excel at P<0.05. Results revealed a significant difference in physical growth of plants in all treatments with steady increase up to 90 DAP and decrease at 105 DAP in both Districts. Yield average was 37.67 t/ha and 30.83 t/ha in Rubavu and Nyabihu Districts respectively. It was the highest for dead mulch at 57.6 t/ha in Rubavu and 43.0 t/ha in Nyabihu District. It was followed by Lablab spp at 42.3 t/ha for Rubavu and 37.3 t/ha for Nyabihu District. Yield increment was 42.0 % and 3.8 % in Nyabihu and Rubavu Districts respectively. Dead mulch and Lablab contributed more to the yield increase and can be recommended as farming practice to increase potato yield in both Districts. [ABSTRACT FROM AUTHOR] |
