Abstract: A research experiment was conducted on cotton during kharif 2015 and 2016 at Regional Agricultural Research Station (RARS), Warangal (Telangana) “To study the Influence of methods and stage of application of zinc, magnesium and boron on yield attributes, yield and micronutrients uptake of cotton in rainfed alfisols”. Pooled results indicated that, foliar application of ZnSO4 @ 0.2% at 30 days, ZnSO4 + Borax @ 0.2% each at 45 days, Borax @ 0.2% + MgSO4 @ 1% at 60 days and MgSO4 @ 1% at 75 days after sowing along with soil application of recommended dose of fertilisers (RDF) recorded significantly higher sympodial branches, number of bolls per plant, seed cotton yield i.e 21.90, 43, 2811 kg ha-1, respectively over other treatments. However, significantly higher Zn, Cu, Fe and Mn uptake i.e 191, 54.14, 2861 and 172 g ha-1, respectively were found with foliar application of ZnSO4 @ 0.2% at 30 days, ZnSO4 + Borax @ 0.2% each at 45 days, Borax @ 0.2% + MgSO4 @ 1% at 60 days and MgSO4 @ 1% at 75 days after sowing along with soil application of recommended dose of fertilisers.
