Influences of Different Soil Erosion Control Methods on Bean Production
Characteristics and yield
Erosion negatively affects crop yields and decreases crop productivity.
It removes nutrients, reduces rooting depth, and damages soil structure,
resulting in negative nutrient balances and lower crop yields. A study
for two years was conducted using three soil erosion control methods to
appraise the method which could effectively control erosion and improve
bean production characteristics on a hill more prone to erosion.
Designed on three different plots ( P1, P2, P3) divided in four sub
plots (S1, S2, S3, S4), these methods were traditional plowing method
(M1); anti-erosive hedges planting method (M2) and anti-erosive hedges
coupled with anti-erosive ditches (M3). The recorded parameters were the
number of: pods, full pods and grains, as well as the average yield
weight. After analysis with SPSS and Advanced excel, results showed no
significant difference between M1 and M2 but highlighted the significant
effects of M3 method in improving the number of: pods, full pods and
grains. Likewise, this method has somehow enhanced the average yield
weight. These outcomes suggest M3 as the most effective method in
enhancing bean production characteristics and yield at Buhoro hill.
