Influence of integrated nitrogen management on growth and yield attributes of foxtail millet genotypes

Abstract

A field experiment was conducted during the kharif season of 2018 on Foxtail millet of varieties SIA 3156 and SIA 326 (PRASAD) at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P). The experiment was laid out in Randomized Block Design with 6 treatments combinations, consisting of two varieties of Foxtail millet ( SIA 3156, SIA 326) and nitrogen management viz., Farmer’s practice (NPK= 40:20:0), 100% RDF (NPK= 50:30:20)), 75% RD N + 25% N through PM, 75% RD N + 25% N through PM + Azospirillum SI, 50% RD N + 50% N through PM and 50% RD N + 50% N through PM + Azospirillum SI. The Experiment revealed that in variety SIA 3156, integration of inorganic fertilizer of 75% RD N through Urea + 25% N through PM resulted in statistically significant plant height (93.07 cm) and obtaining highest plant dry weight (6.09 g). In this treatment, all the growth parameter viz. Number of Tiller per running row meter, LAI and Yield parameter viz. number of effective tiller per running roe meter, length of panicle and test weight (1000 seeds0 were at par with the highest observation recorded. In variety SIA 326, the experiment reveals that 75% RD N through Urea+ 25% N through Poultry Manure+ Azospirillum SI was found out to be the best treatment which result in statistically significant plant height (99.80 cm), highest plant dry weight (7.35 g) and highest test weight (3.29 g) other growth and yield parameters were found to be at par with the highest observation recorded.
