The Impact of Organic Manures on the Soil Quality. A study on Organic Nutrition in Crop Rotation of

Doctoral Thesis / Dissertation from the year 2019 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 8.10, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, course: Soil Science, language: English, abstract: A study was conducted to assess the impact of different organic manures on soil properties and growth parameters in okra-broccoli cropping sequence. Study area lies in between 32°39' N latitude and 74°47' E longitude at an elevation of 332 meters above the mean sea level in the Shivalik foothill plains of North-Western Himalayas. Surface soil sampling from 0-15 cm depth was done randomly from four spots of the field prior to start of the experiment.The data on various characters studied during the course of investigation were statistically analyzed by using Tukey's test with an aim to figure out which groups in our sample differ by using Honest Significant Difference. Further, influence of organic manures on soil physical, chemical and biological properties was studied and was found that there was a significant impact of organic manures on soil physical properties viz. WHC, BD and IR.In nutrient status, organic manures reviewed a positive impact on Available N, P and Fe. However, available K, S, Zn, Cu, Mn, Total N, Exch. Ca and Mg were found to be non-significant in the experiment. All growth parameters of okra and broccoli including okra yield and curd weight showed significant increase except number of leaves in broccoli.
