Abstract:
A field experiment was carried out at Agroforestry research farm, Department of Forestry, JNKVV, Jabalpur, Madhya Pradesh, to assess the effect of pruning and weedicide application on soil properties in Rice-Dalbergia Sissoo based agroforestry system. The result revealed that EC, pH and organic carbon was at par during the experiment and the available N, P and K increases with decreasing intensities from 75 to no pruning. Hence highest value was recorded under no pruning which was significantly superior over other pruning treatments except P 25. The 75% pruning and open condition recorded the lowest content NPK. From pooled data it was noted that with the increasing of pruning intensity significantly decreased the NPK status of soil hence higher content of 308.14, 14.78 and 387.18 kg/ha of nitrogen, phosphorus and potassium respectively. Where, the lowest NPK status was observed under open condition and possess the values of 247.68, 11.26 and 282.12 kg/ ha respectively. Thus, the study suggests that Agroforestry land use system proved most compatible for increment in soil nutrient status as compare to sole cropping.
