ABSTRACT
A field experiment was carried out at Servaikaranmadam of Thoothukudi district to study the impact of organic manure on physical properties of sandy clay loam soil. Goat Manure (GM), Vermicompost (VC) and Swine Manure (SM) are organically manured at 8, 12.5, and 17 t ha-1 respectively which are used solely and with double and triple manure combination. Results of the study on physical properties of soil showed that animal wastes improved the Water Holding Capacity(WHC), Pore Space (PS), Saturated Moisture (SM), Hydraulic Conductivity(HC), Permeability (PE). However, it declines the soil Bulk density (BD) and Particle Density (PD). Results of statistical analysis done by one-way ANOVA reported a negative correlation for BD and PD with Black Gram (Vigna Mungo. L.) yield and a significant (P<0.05) positive correlation was observed with HC, and PE respectively. The results of SEM images show the surface morphology of the implemented animal wastes and confirms the decomposition of animal wastes and gets incorporated into the macrospores of the soil which was not noticed in the control plot. Conclusively, the integrated use of Goat manure and Vermicompost (GV) 17 t ha-1 has produced Black gram yield of 990 kg ha-1 that can be suggested to improve crop productivity on sustainable basis. This field study will be beneficial in preparing sustainable nutrient management programs in future to promote black gram productivity with high efficiency and minimum nutrient loss.
