Field investigations were carried out at Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalai Nagar (India) to identify sustainable, eco-friendly and economically viable agronomic techniques for irrigated cotton. The conjoint application of 1-napthalene acetic acid (NAA) @ 40 ppm with 60 kg sulphur (S) + 5 kg zinc (Zn) + 0.5 kg boron (B) ha-1 had a remarkable influence on the growth, yield attributes, yield and economics of irrigated cotton. However, it was on par with application of NAA @ 40 ppm and 45 kg S + 5 kg Zn + 0.5 kg B ha-1. With regard to the economics of treatments imposed in this investigation, the trend was different from the earlier parameters discussed. This was due to the high cost involved in excessive application of sulphur. Application of NAA @ 40 ppm and 45 kg S + 5 kg Zn + 0.5 kg B ha-1 exhibited a salutary effect on economic analysis in terms of net return and return rupee-1 invested in irrigated cotton.
