Abstract
A study was conducted at Organic Farming Research Centre of SKUAST -Jammu during 2016 to 2017 to find out the impact of organic manures on soil organic carbon, physical and crop growth parameters Okra-Dhaincha-Broccoli cropping sequence. The Soil Organic Carbon was analyzed by Chromic acid wet digestion method. However, in soil physical properties Bulk density was analyzed by Core method, water holding capacity by Keen Rackzowski Method and Infiltration rate by Double Ring Method. In the experiment, soil organic carbon was found non-significant in experiment. Bulk density was found to be significant in year 2016 and 2017 as very captivating change was observed as compared to control; T8 as the lowest value treatment with value 1.26 g cm-3 was recorded. Water holding capacity was found to be significant in year 2016 and 2017 as very positive change was observed as compared to control as WHC with highest value 43.68% was noted in T8 in 2017. Infiltration rate was also found to be significant in year 2016-17 as very positive change was observed as compared to control. Significant improvement in root volume, root length was observed in Okra and same was noted in size of curd in broccoli as compared to control. The significant impact of organic manures on soil quality parameters will provide a new way to improve the soil health and productivity in a sustainable way.
Keywords: Infiltration rate, organic manures, root volume, root length, soil organic carbon, size of curd, water holding capacity, bulk density.
