Weed control methods affect growth, yield and economic returns in groundnut
Journal Title: Annals of West University of Timisoara, ser. Biology - Year 2016, Vol 19, Issue 1
Abstract
Field trials were carried during the rainy seasons of 2010 and 2011 to evaluate the effects of weed control methods on growth, yield and economic returns in two varieties of groundnut (Arachis hypogeal L cv Samnut 10 and MK 373). The results showed that Brachiaria deflexa, Cleome viscosa, Cochlospermum planchoni, Dactyloctenium aegyptium and Daniellia oliveri were the most preponderant in all twenty-six weed species encountered. Plots where rice straw mulch at 0.1 m depth + one hand weeding at 6 weeks after Planting (WAP) Pendimethalin at 1.5/ha + one hand weeding at 6 WAP and two hand weeding at 3 and 6 weeks after planting reduced weed population better than those recorded from sole application of rice straw mulch at 0.1m depth and Pendimethalin at 1.5 ha-1. The weed free check showed most effective weed reduction (93-96%). The presence of weeds reduced crop yield by 51%. Highest seed yield of 674.4 kg ha-1 and 971.6kg ha-1 in Samnut 10 and MK 373 respectively when average for the two years was recorded from rice straw mulch at 0.1m depth + one hand weeding 6WAP and followed in decreasing order of magnitude by those of two hand weeding at 3 and 6 WAP, Pendimethalin at 1.51 ha-1 + one hand weeding at 6 WAP, sole application of rice straw mulch at 0.1 m depth and Pendimethalin at 1.51 ha-1 The production value in terms of economic returns was highest under rice straw mulch at 0.1 m depth + one hand weeding at 6 WAP (₦77,240 and ₦107,000 ha-1) having maximum cost benefit of 2.15 and 2.41 in Samnut 10 and MK 373 respectively in 2010. In 2011, the same treatment showed highest net returns of ₦ 166,040 and N 209,600 ha-1with maximum benefit cost ratio of 3.42 and 3.97 in Samnut 10 and MK 373 respectively. The results suggested that the use of rice straw mulch at 0.1m depth + one hand weeding at 6 WAP was more economically viable as well as effective in weed control with the advantages of increasing crop growing environment for better yield.
