| Abstract: |
The aim of this experiment was to study the effect of foliar application of nano urea and nano zinc on growth and yield of single cut forage sorghum. The experiment was laid out during kharif season, June, 2022 at Instructional Dairy Farm, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, India. The field was designed in a randomized block design having eleven treatments which were replicated thrice. The available treatments consist of different combinations of RDF and nano fertilizers containing nano urea and nano zinc. The implementation of treatment, T5 has significantly effect on plant height, leaf: stem ratio, SPAD value, mean CGR, mean RGR over other treatment combinations. Green and dry fodder yield were noted highest under T5 (75.3 t/ha) and (16.6 t/ha) over other treatments. T5 incurred the highest cost of cultivation (Rs. 37,821/ha), whereas T1 had the lowest (Rs. 34,495/ha). Despite its higher cost, T5-60 kg N/ha as basal + NU & NZn spray at 30 and 60 DAS, yielded the highest net return (Rs. 112,779/ha), while T1-T1: 60 kg N/ha as basal + top dressing of 30 kg N/ha at 30 DAS (RDF) recorded the highest benefit-cost (B:C) ratio of 3.2 among all treatments. Foliar application of nano urea and nano zinc at 30 and 60 days after sowing (DAS), in combination with a basal application of 60 kg N/ha, significantly enhances the yield and net returns of single-cut forage sorghum.
