A field experiment was conducted on red soils (Kandic paleustalfs) of Zonal Agricultural Research Station, GKVK, Bangalore during kharif 2008-09 to develop a targeted yield equation for carrot crop. After developing three levels of fertility gradient with respect to available NPK in soil, the main experiment was conducted by taking carrot as a test crop. Initial soil data, carrot ischolar_main yield and NPK uptake by carrot crop were used for obtaining four important basic parameters, viz., nutrients required to produce a quintal of carrot ischolar_mains (NR%), contribution of nutrients from fertilizers (CF%), contribution of nutrients from soil (CS%) and contribution of nutrients from organic matter (%C-OM). These parameters were used for developing fertilizer-adjustment targeted yield equation. Comparison of the present soil testing laboratory method with Soil Test Crop Response approach of fertilizer recommendation clearly indicated superiority of STCR targeted yield approach for efficient and economic use of fertilizers to attain the required yield target.Keywords

A survey work on quality of red soils along the water course of SBC carried out during 2014-15 which indicated that soil quality parameters such as WSA, MWHC AW, SEI, BD, total soil porosity, pH, SOC, CEC, MBC and DHA were comparatively better in tail reach soils than in head and middle reach soils as the amount of water discharged at soils of later reaches was more than that of farmer reach and in general soil quality was not deteriorated as much as excepted as the land use was paddy the bellow ground portion of paddy crop is being incorporated into the soil year after the year added organic matter to the soil and in addition to this coarser soil texture did not encourage accumulation of salt in soils and thus, the significant correlation of soil quality parameter with both particle size classes and SOC was evident of it.Keywords

The survey work was carried out during the year 2014-15 at Shahapur branch canal of Yadgir district, Karnataka and studied the fertility status of soil along the water course of canal command area. Available nitrogen content was comparatively more in sub surface soils than in surface soils all along the water course of distributory-14. Available phosphorus status in soils at the tail reach was comparatively more than that of head reach. Irrespective of surface and sub surface soils available potassium status was medium and was comparatively low in sub surface than in surface soils. However, increasing trend of potassium from head to tail via middle reach along the water course was observed. Available sulphur status was medium in surface and low in sub surface soils all along the water course. Available nitrogen, phosphorus, potassium and sulphur were strongly correlated with organic carbon (0.950, 0.989, 0.986 and 0.989), CEC (-0.841, -0.895, -0.934 and -0.946) and dehydrogenase activity (0.934, 0.979, 0.980 and 0.982). Higher concentration of DTPA extractable micronutrients namely, Fe, Cu and Zn in surface than in sub surface soils was observed all along the water course. However, fertility status of soils along the water course was low with respect to both available N and P, medium with respect to available K, S, Fe and Zn while high with respect to available Cu and Mn.Keywords
