|Abstract:||The present investigation was undertaken during August 1997 to February 1998 at Mahatma Phule Krishi Vidyapeeth, Rahuri to study the growth pattern of pomegranate saplings under different water regimes based on IW/CPE ratio in Vertisols. The pot culture experiment was laid out in completely randomised design with four treatments and five replications. Four water regimes viz., 1.0, 0.8, 0.6 and 0.4 IW/CPE ratio were maintained. Soil used for experiment was characterised as clay in texture. Soil was low in available N, medium in available P and very high in available K content. It was slightly alkaline (pH 7.77) in reaction with low electrolyte concentration. The biometric observations like survival percentage, plant height, number of internodes, leaf number, total leaf area per plant, dry matter content and root : shoot ratio were recorded and efforts were also made to study the physiological response of pomegranate in terms of stomatal conductance. Inter relationship between different weather parameters and plant growth attributes was also observed. Plant growth attributes were recorded to be better at water regime of 1.0 IW/CPE ratio over other water regimes. The growth attributes viz., plant height, number of internodes, leaf number, leaf area per plant and dry matter were recorded to be maximum at 1.0 IW/CPE level (105.26 cm, 230.2, 776.0, 6031.304 cm2 and 53.26 g respectively). Water regime treatment of 0.8 IW/CPE ratio recorded 85-90 per cent growth, of the maximum (1.0 IW/CPE) regarding above growth attributes. Minimum growth in terms of above attributes (71.2 cm, 140.2, 447.8, 3537.226 cm2, 31.48 g, respectively) was recorded at water regime treatment of 0.4 IW/CPE ratio. The inter-relationship between weather parameters and plant growth attributes showed need for higher temperature and longer sunshine hours for better plant growth. Stomatal behaviour under water stress condition showed reduction in stomatal conductance in plants under water regime of 0.4 IW/CPE ratio.|
