Abstract:
Field studies were conducted at PFDC farm, of Tamil Nadu Agricultural University, Coimbatore to evaluate the effect of plastic mulching on grafted brinjal under drip irrigation. The experiments were laid in Strip Plot Design with twenty seven treatments which included three mulching levels such as 25 µ thickness plastic mulch, 50 µ thickness plastic mulch and control; three Irrigation levels at 60 per cent ET0, 80 per cent ET0 and 100 per cent ET0 and three fertigation levels with 80 per cent, 100 per cent and 120 per cent RDF which were replicated thrice. Daily water requirement was calculated based monthly average evaporation the results showed that total water requirement for the growth period under drip irrigation was 396.00 mm with mulch at 80 per cent ET0 level and 495.00 mm without mulch at 100 per cent ET0 level. It’s observed that treatment gave highest yield of 83.3 t.ha-1 under 25 µ thickness plastic mulch at 80 per cent ET0 level and 100 per cent RDF and lowest yield of 18.1 t.ha-1 in control plot with 60 per cent ET0 and 80 per cent RDF. It can be concluded drip irrigation can save 16.17 per cent of water with mulch as compared without mulch condition.
