Performance of conservation agriculture practices on the physical growth and yield of broccoli (Brassica oleracea L. var. italica) in Nyabihu District
Abstract
This study aims to investigate the effect of various tillage methods on physical growth and yield of broccoli (Brassica oleracea L. var. italica). The experiment was conducted in farmers’field during seasons 2022B (March-June) and 2023A (September-February). Experiment was laid out in a Randomized Complete Block Design (RCBD) in Nyabihu District in four replications and five treatments which were T1(Conventional tillage), T2(zero tillage), T3(minimum tillage), T4(medium tillage) and T5(maximum tillage). Data were collected on physical growth at 15 days after planting (DAP) with interval of 15 days up to 45 DAP, while yield data were collected after harvesting. The Analysis of variance (ANOVA) was done following OPSTAT, statistical analysis tool, at P<0.05 and Least Significant Difference (LSD) was used for mean separation. There was a significant difference in physical growth and yield of broccoli. Minimum tillage outperformed other treatments both in growth and yield while zero tillage was the least. Yield was the highest with 31.32t/ha for minimum tillage and the lowest for maximum tillage with 10.18t/ha both in 2023A.Yield increment was highest for minimum tillage and lowest for zero and maximum tillage. Minimum tillage is advised to increase yield of broccoli and environmental conservation.
