STUDIES ON GROWTH PERFORMANCE OF TREE SPECIES UNDER TREATED DOMESTIC SEWAGE WATER IRRIGATION AT UKKADAM COIMBATORE IN TAMIL NADU
Keywords:Species, Sewage water, Irrigation, Survival percent
The present study was under taken to compare the growth and development of five fast growing tree species irrigated with treated domestic sewage water. Five fast growing tree species viz., Neolamarckia cadamba, Dalbergia sissoo, Eucalyptus tereticornis, Melia dubia and Acrocarpus fraxinifolius were planted in Randomized Block Design and irrigated with treated domestic sewage water for evaluation of their growth performance. The survival percentage of above planted species after three months was 97.50 % (Melia dubia), 92.50 % (Eucalyptus tereticornis), 85 % (Dalbergia sissoo), 82.50 % (Acrocarpus fraxinifolius) and 77.50 % (Neolamarckia cadamba). Biometric observations at 6 MAP revealed that there was a significant increase in plant height and collar diameter and volume index viz., Melia dubia, Eucalyptus tereticornis and Dalbergia sissoo showed good performance, those selected tree species are highly recommended for industrial plantation under irrigation of treated domestic sewage water.
