On farm field experiment on effect of soil amendments in relation to soil water retention capacity and soil fertility in redgram were taken up in Alfisols of NSP left canal command area during Kharif 2006 and Kharif 2007 at pilot area Ganapavaram of Nagarjuna Sagar Project left canal command under A.P. water management project funded by FAO. The trial was carried with the farmers participatory mode to study the impact of application of tank silt and farm yard manure as soil amendments in relation to soil water retention capacity and soil fertility and on crop yield of redgram. The five treatments consisted of 5t FYM/ha, 10t FYM/ ha, 20t tank silt/ha, 30t tank silt/ha and RDF. Application of 20 t of tank silt + RDF and 30 t of tank silt + RDF application recorded highest grain yield of 2290 kg ha-1 and 2180 kg ha-1 during Kharif, 2006 and 20 t of tank silt + RDF recorded highest grain yield of 2280 kg/ha followed by application of 30 t of tank silt+ RDF (2130 kg/ha) and application of 10 t of FYM+ RDF (2040 kg/ha) during Kharif, 2007, respectively. Post harvest soil analysis revealed that the organic carbon content was high in 10 t FYM + RDF where as the application of increased tank silt recorded increase in water holding capacity during the both the years.Keywords

Studies undertaken to assess the nutrient status of soils of pilot area Ganapavaram of 24 L Minor and Muktheswara Puram Major of Nagarjuna Sagar Project left canal command of Nalgonda district of Andhra Pradesh have been studied. Profile wise nutrient status in soil profiles of pilot area revealed that the soils were low to medium in available nitrogen (94 - 219 kg ha-1), low to high in available phosphorus (4.4 to 45.5 kg ha-1) and low to high in available potassium (98 to 482 kg ha-1). The DTPA extractable available micronutrients Zn, Cu, Mn and Fe ranged from 0. 24 to 2.52 mg kg-1, 1.20 to 4.59 mg kg-1, 1.18 to 15.65 mg kg-1 and 1.67 to 49.1 mg kg-1 soil, respectively. Soils were low to medium in available nitrogen, high in available phosphorus and medium to high available potassium in the surface horizons and in case of available micronutrients deficient to sufficient in Zn and sufficient in available Cu, Fe and Mn in the surface layers of the soil profiles.Keywords
