PHYSICO- CHEMICAL CHARACTERISATION OF ORATHUPALAYAM RESERVOIR WATER AND ITS EFFECT ON THE GROWTH PERFORMANCE OF PEARL MILLET (Pennisetum typhoides ICMV- 221)

Abstract

Physico-chemical characterisation of Orathupalayam reservoir water, Tirupur, Tamilnadu indicated that the vaiues for pH, EC, TS, TSS, TDS, Total alkalinity, TH, DO, BOD, COD, free C02) Ca, Mg, chloride, sulphate, phosphate and nitrites were on the higher side of the permissible limits of BIS (Bureau of Indian Standards). Present investigation deais with the growth performance study of pearl millet on the reservoir water, which reveals that the soils of control site and site 1 experienced minimum changes in soil properties due to irrigation with water and performed better than other sampling sites. Much affected was site 5 soil sample which produced lesser yield.
