A field experiment was conducted to study the tillage and manuring effect on soil physical properties. Three tillage treatment were assigned as main plots, T0, T1 and T2 tillage and four manuring treatments such as, M0 - recommended dose of N, P, K and M1 -1/2 recommended dose + cow dung @ 5t ha‾1, M2 - cowdung 2.5t ha‾1+ rice straw @ 2.5t ha‾1 + ½ recommended dose of N,P,K and M3 - rice straw @ 5t ha‾1 +1/2 recommended of N, P, K and assigned in different split plots. Both tillage and manuring had significant effect on soil physical properties like bulk density, air filled porosity, soil moisture and soil organic matter contents. The bulk density was increased with increasing soil depth and the bulk density was influenced more or less similar to tillage by manuring up to 30 cm depth of soil. Highest air-filled porosity 15.28% was recorded at 20-30 cm depth tillage and also in M2 manuring treatment (12.67%) The interaction effect of tillage and manuring on soil air filled porosity was significant in surface soil but considering the soil depth up to 30cm there was no significant difference and the value ranged from 7.32 to 11.80%. The maximum soil moisture of 48.21 and 48.10% were obtained under deep tillage (T2) and in M2 manuring treatment respectively. In no tillage average highest organic matter content was observed. |
