| dc.description.abstract | yield and certain quality parameters of cotton in vertisol, under irrigated condition during kharif 2006-07, at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. The experiment consisted nine treatments with three replications and was laid out in randomized block design. The results indicated that different levels of sulphur, iron, zinc and their combination significantly increased the seed cotton yield, ginning percentage and seed index. Among the sulphur levels (as factomphos), application of 50 kg S per ha, recorded the highest seed cotton yield (19.50 q/ha), ginning percentage (43.00%) and seed index (9.10) and were par with the 25 kg S per ha and was significantly superior over control. Among the iron levels (as FeSO4), application of 50 kg Fe per ha recorded the highest seed cotton yield (18.50 q/ha), ginning percentage (39.10%) and seed index (9.00) and was significantly higher over control. Among the levels of zinc (as ZnSO4) application of 50 kg Zn per ha, recorded the highest seed cotton yield (20.50 q/ha), ginning percentage (39.50%) and seed index (9.10) and on par with application of 25 kg per ha and was significantly superior over control. Combined application of sulphur, iron and zinc each at 50 kg per ha (T9) recorded the highest seed cotton yield (98.50 q/ha), ginning percentage (43.00%) and seed index (9.81) which were on par with treatment (T8) receiving sulphur, iron zinc each at 25 kg per ha and was significantly higher over rest of the treatments. The treatment T9 recorded the highest nutrient uptake (N, P, K, S, Fe and Zn) and on par with the treatment T8 and was significantly superior over rest of the treatments. Further, combined application of sulphur, iron and zinc each at 25 kg per ha recorded the highest B:C ratio of 2.51 and net returns of Rs.33,396 proved to be economically more feasible. | en_US |
