Summary, etc Response of nine Hevea clones in partial irrigation and their growth performance during the immature phase was studied in the North Konkan which is non-traditional area for rubber. The area has effective annual dry period of six months (December to May) or more, with more pronounced soil moisture stress in the latter half of the dry period. Growth of clones in terms of relative growth rates (RGR) during wet, irrigated dry and unirrigated dry seasons during immature period was studied. Growth of clones in terms of relative growth rates (RGR) during wet, irrigated dry and unirrigated dry seasons during immature period was studied from June 1986 to February 1991. The mean annual RGR of clones during irrigated and unirrigated years were 842 and 493 g per kg per season respectively. During wet periods clones Tjir 1 and RRIM 501 were leading in growth, followed by PB 235, GT 1, RRIM 612 and RRIM 600. The RGR were 555, 555, 544, 515 and 404 g per kg per season respectively. Except PB 235, response of other clones to irrigation was comparable. In unirrigated dry seasons RGRs of clones RRIM 600, PR 107 and RRIM 612 were significantly higher and the values were 165, 100 and 51 g per kg per season respectively. There was general decline in the mean RGR in the wet season when it succeeded irrigated dry season. Clones which grew well in wet season did not grow well in unirrigated dry season. Clones which grew well in wet season did not grow well in unirrigated dry season. Clones which grew well in wet season did not grow well in unirrigated dry season and vice versa. At the end of eight and a half years, the growth of RRIM 600, RRIM 501 and RRIM 612 were found to be better. The results indicated advantages of irrigation during immature phase.
