Influence of Fertilization Levels on Stomatal Resistance, SLW And RWC at Different Growth Stages of Bt-Cotton

A field experiment was conducted during kharif, 2013 at agricultural college farm, Raichur. The experimental design was laid out in randomized complete block (RCBD) with nine treatments replicated thrice. Application of higher doses of nutrients i.e. 150% RDF (225: 112.5: 112.5 NPK kg/ha) recorded significantly higher Specific leaf weight (SLW), Relative water content (RWC) and lower Leaf stomatal resistance was observed followed by 150 per cent RDN, 100 per cent RDN, 50 per cent RDN and 50 per cent RDF. The lowest values were observed for Specific leaf weight (SLW) and Relative water content (RWC) except leaf stomatal resistance from application of STCR (Target 2.0 t/ha) (0: 25.5: 24.4 kg NPK/ha).
