Effects of Mulching Materials on Physical Properties of Soil and Grain Yield of Sesame

摘要: This experiment was conducted to investigate the effect of mulching materials on emergence rate, root dry weight and grain sesame using variety Poong Nyun Ggae also their effects physical properties soil, evapotranspiration weed growth respective plots were studied. The soil water holding capacity at with polyethylene film straw increased 5.4%, 2.8% non-mulched plot respectively. maximum temperature raised up 4 by applying clear dropped down 7 straw. minimum 2 3 In early stage, better than those non mulching, so in rate. late strength high porosity, aeration infiltration rate mulchings. Total great concentrated mainly upper 10 cm profile. amount weeds collected least black mulching. There little difference among treatments. yield 57% 25%
