ZINC AND MAGNESIUM NUTRITION Chelated zinc (Zintrac) and magnesium oxide (Magflo) are being compared with zinc sulphate pentahydrate and magnesium sulphate pentahydrate for Zn and Mg nutrition.

IRON TOXCITY The experiment on toxic effects of excess iron present in foliar applied Zinc Sulphate is in progress.

IRRIGATION Effect of drip irrigation and fertigation on made tea yield is being studied in Nilgiris.

EFFICIENCY OF DRIP AND SPRINKLER IRRIGATION is being worked out at most drought affected districts like central Travancore, Wayanad, Nilgris and Koppa. Efficiency of drip irrigation is being investigated on the growth of young tea at Koppa.

SECONDARY NUTRIENTS Field experiments on secondary nutrients ( S and Mg) is in progress at Wayanad,

ANALYTICAL SERVICE Besides conducting research, we are offering analytical service primarily to our members, firm members and also to non-members at a nominal charge. The service include,

UREA HYDROLYSIS Under the financial support of NTRF laboratory experiments are being conducted to find out the influence of soil moisture, soil pH, temperature and nitrification inhibiton on tea soils are worked out.

N-MINERALISATION Laboratory experiments are in progress rare out the important aspects of nitrification, ammonification and net mineralisation of nitrogen as influenced by soil pH, soil moisture, temperature and organic as well as inorganic sources.
