Effect Of Tillage Practices On The Growth And Yield Of Groundnuts (Arachis Hypogea) At Dambatta, Kano, NIGERIA.

摘要

ABSTRACT: A field trial was conducted during 2010 rainy season at the Research and Teaching farm of Audu Bako college of Agriculture Dambatta, to evaluate the influence of different tillage practices on the growth and yield of groundnut (Arachis hypogea). The tillagepractices evaluated weremaximum tillage(primary and secondary), minimum tillage and zero tillage practices. The combination was replicated three times in a Randomized Complete Block Design (RCBD). Hand-held hoe was manually used to prepare the soil to the specific depth. The result of this the work indicates that zero tillage was significantly differentfrom all the parameters measured which include plant height, canopy spread, shelling percentage, one hundred seed weight and pod yield in which 26.86cm, 57.30cm, 48.32%, 60.25g and 200.28kg/ha as against 23.49cmand 20.84cm, 50.05cm, and 43.54% and 32.42%, 52.32g and 50.14g and 160kg/ha and 110.25kg/ha, respectively obtained under minimum and maximum tillage respectively.
