ONGOING RESEARCH WORK

Toxicity Toxic limits for Zn, Fe, Al and Mn were determined and the synergistic and antagonistic effects between the elements were determined. Apart from these elements the toxicity study for other secondary and micronutrients nutrients is in progress.

IRON TOXCITY The experiment on toxic effect of excess iron present in foliar.

IRRIGATION Effect of drip and fertigation on made tea yield has been studied and a couple of experiments are being continued to confirm the results.



EFFICIENCY OF DRIP AND SPRINKLER IRRIGATION It is being worked out for severely drought affected districts like Central Travancore, Wayanad, Nilgiris and Chikmagalur. Efficiency of drip irrigation is being investigated on the growth of young tea at Koppa in Karnataka.

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

ORGANIC TEA CULTIVATION Soil application of various green manures like crotalaria, glyrecedia and sesbania is being investigated to compare the efficacy of different green manures on productivity and quality tea.

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