Abstract
This study emphasis on the impact of Swine manure (SM), Vermi compost (VC) and combination of both the manures (SMVC) treatments on physico-chemical, chemical and physical properties of Sandy Clay Loam (SCL) soil and on the growth parameters of the Black Gram (Vigna Mungo.L.). A field experiment was conducted with three different treatments viz., sole application of SM, VC and combined application of both manures SMVC at three different doses of 8, 12.5 and 17 t ha-1 respectively. Soil properties got better enhancement for the amendment of swine manure as a single treatment at 17 t ha-1 (T3) and also responded well when combined usage with vermicompost at 17 t ha-1 (T9) too. The highest yield of 512 kg ha-1 was obtained for the treatment T9 and it is also in par with T3 of 510 kg ha-1, and the lowest yield 94 kg ha-1 was acquired with the control plot (T10). Chemical properties like Nitrogen (N) and Phosphorus (P) and Potassium (K) got enriched after amendment with organic supplements, hence the development in the growing parameters viz., height of the plant and number of leaves per plant got increased. Bulk density takes place a cardinal role in the enhancement of water holding capacity along with saturated moisture (SaM) and thereby increases the yield. Statistical analysis has been done using SPSS (P<0.05) and height of the plant in 45DAS was found to be significantly responded to the crop yield. Present finding revealed that swine manure could be reliably used to enhance the productivity of Black Gram (Vigna Mungo.L.) instead of preferring to the Chemical Fertilizers (CF) and deteriorating the environmental ecosystem and to reduce the first concern of FYM.
