Abstract
The field experiment was conducted during ZAID season 2023 at experimental field of Crop Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India. In the present study, the treatments consisting three levels of recommended dose of fertilizer (RDF) viz., 100% RDF (60-30-30 Kg/ha), 75% RDF (45-22.5-22.5 Kg/ha) and 50% RDF (30-15-15 kg/ha) along with three different micro nutrients viz., Zinc - 0.5 kg/ha, Boron - 0.5 kg/ha and Iron - 0.5 kg/ha. The experiment was laid out in a randomized block design with 10 treatments each replicated thrice. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.3), low available nitrogen (278.93 kg/ha), medium available phosphorus (15.4 kg/ha) and medium available potassium (173.7 kg/ha). Results revealed that higher plant height (84.20 cm), plant dry weight (10.61 g), number of tillers/ hill (4.53), length of ears (9.20 cm), number of ears/plant (4.47), test weight (3.47 g), grain yield (1.22 t/ha), straw yield (2.80 t/ha) were recorded in treatment 8 (NPK 100% RDF+ Boron 0.5 kg/ha). Maximum gross return (INR 48,408.33), net return (INR 30,913.33) and B:C ratio (1.77) were also recorded in treatment 8 (NPK 100% RDF + Boron 0.5 kg/ha). It can be concluded that the application of NPK 100% RDF +Boron 0.5kg/ha (Treatment 8) recorded higher yield and benefit cost ratio in Foxtail millet.
