| Abstract/Description: | Field experiments were conducted in a strip plot design at the experimental farm of ICAR-CTRIResearch Station, Vedasandur, Tamil Nadu during 2013-14 and 2014-15 with four main plot treatments viz., Drip fertigation with 100% RDN (Recommended dose of Nitrogen @ 125 kg/ha), Drip irrigation with 100% RDN (Soil applied), Alternate furrow irrigation and furrow irrigation and three sub-plots with different dates of planting viz. October 1st fortnight, November 1st fortnight and December 1st fortnight with 3 replications. Drip treatments viz. Drip fertigation with 100% RDN and drip irrigation with soil applied 100 % RDN recorded significantly higher first grade leaf yield (FGLY) and Total cured leaf yield (TCLY) over the alternate furrow and furrow irrigation methods. The increase in FGLY and TCLY was 9 and 10 % respectively with drip irrigation+100% RDN, soil applied, over the furrow irrigation. Water saving in drip treatments was 61% over the furrow irrigation. Planting hybrid chewing tobacco during October1st fortnight increased the FGLY and TCLY by 64 and 34 % over the December 1st fortnight planting. Water use efficiency (WUE) was higher with drip treatments (23.6-23.7 kg/ha-mm) and October 1st fortnight planting (20.6 kg/ha-mm). Drip irrigation+100% RDN soil applied and October 1st fortnight plant increased the net return and B:C ratio. Higher residual soil NPK and lamina NPK uptake was recorded with drip treatments and planting the hybrid chewing tobacco during October 1st fortnight. It could be concluded that drip fertigation with 100% RDN and October 1st fortnight planting could be recommended for chewing tobacco in Tamil Nadu for higher yield , net returns and water use efficiency |
