Research Interests :
Different Crops and their fertility management
Problematic soils and their management
Reclamation of saline and water logged soils and their management.
Professional recognition :
As a Principal Scientist (Soil Science) at AP Water management project, Bapatla, developed suitable nutrient management practices under NSP canal command area.
Involved in the development of drainage technologies for reclamation of water logged and salt affected soils. Observed that soil salinity was decreased in these areas after installation of subsurface drainage system.
Involved in the development of technologies for less water use rice production in Krishna Western Delta canal command area of A.P.
As a professor (Soil Science) at Agricultural College, Bapatla had taken PG classes.
As a Programme Coordinator, KVK, Darsi, conducted capacity building Programmes for Women farmers, Rural youth and training to master trainers.
Application of Zn through any form i.e. Zinc Sulphate (or) nano Zinc showed positive results in yield and growth of the black gram crop growing in Zinc deficit soils. But the grain Zinc content was highest in nano Zinc sprayed @ 2 g /15 lit at 25 and 40 DAS.
Apex and Zonal soil plant fertilizer referral laboratory was established at RARS, Lam, Guntur with the budget of 32.5 lakhs.
Survey was conducted in paddy-maize growing areas, 30 permanent locations were selected on GPS data for 3 years. It was found that the farmers applied higher doses of fertilizers than the RDF which led to higher P content in the soil.
A study was conducted on soil properties around the KCP cement factory, Macherla for 3 years and the results revealed that the soil pH was decreased from alkaline to neutral, with increase in distance from cement industry where as OC, NPK contents were increased with increase in distance from the cement factory. The soils in the vicinity of cement factory contained heavy metals like Cd, Cr and Pb.
Improvement in soil properties with respect to soil OC, macro and micro nutrient status was recorded in INM treatment (RDF 100% NPK + 10 t/ha FYM) rather than higher doses of inorganic fertilization with 32 years of experimentation.
Organic carbon content increased in organic farming experiment over a period of 7 years in Redgram i.e., from 0.42 to 0.48% whereas, it decreased in inorganic farming i.e., from 0.42 to 0.37%.
Application of Nano urea @ 4 ml/L at 60 and 90 DAS along with basal application of 50 kg urea at 30 DAS showed significantly higher cotton yield, plant height and number of bolls/plant, and this treatment was at par with soil test based nitrogen application.
On a high P Vertisols, 50% RDP along with VAM (12.5 kg/ha) and PSB (5 kg/ha) to cotton was found on par with RDP. Adopting this technology the farmer can save 30 kg P2O5 ha-1.
