There were 11 treatment combinations having spray of two different water soluble fertilizers viz., 19:19:19 and 13:0:45 (0.5 %) ; soil application of micronutrients viz., zinc as zinc sulphate (25 kg ha-1) and boron as borax (2 kg ha-1) along with recommended dose of fertilizer (RDF) (75:75:87.5 kg N, P2O5 and K2O ha-1) and RDF + farm yard manure (FYM) (10 t ha-1). The experiment was laid out in randomized complete block design with three replications. Foliar application of 19:19:19 along with RDF + FYM + ZnSO4 + borax has recorded significantly higher grain and straw yield (3,765 and 4,420 kg ha 1, respectively) and yield parameters like productive tillers (143.7), filled grains per panicle (69.3) and grain weight per panicle (2.56 g). Whereas, significantly lower grain (2,753 kg ha-1) and straw (3,346 kg ha-1) yield was recorded in RDF alone treatment. Total uptake of nitrogen (96 kg ha-1), phosphorus (19 kg ha-1), potassium (101.4 kg ha-1), zinc (971.9 g ha-1) and boron (176.4 g ha-1) was also significantly higher in treatment having foliar application of 19:19:19 along with RDF + FYM + ZnSO4 + borax and was found on par with all other treatments receiving foliar spray of either 19:19:19 or 13:0:45. Similarly, higher net returns (Rs. 33,436 ha-1) was recorded in foliar application of 19:19:19 along with RDF + FYM + ZnSO4 + borax and was found significantly superior over all other treatments except the treatments with foliar application of either 19:19:19 or 13:0:45EnglishThesis
