Effect of Nano-DAP seed treatment and foliar spray on growth, yield attributes and yield of wheat (Triticum aestivum L.)

A field experiment was conducted during kharif2022 at the Research Farm of Department of Agronomy. Experimental site falls under sub-temperate mid hill zone of Himachal Pradesh. It lies in North-West Himalaya in the Palam Valley of Kangra district of Himachal Pradesh, India. To study the Effect of Nano-DAP seed treatment and foliar spray on growth and yield of wheat (Triticum aestivum L.). The experiment was conducted in Randomized Complete Block Design with ten treatments, replicated three times. Application of recommended dose of fertilizers (120:60:30kg/ha) (T2) recorded highest plant height at 30, 60 days after germination while at 90, 120 and at harvest the taller plants height was absorbed in T8 (75% NP + seed treatment @5ml/kg seed + foliar spray @ 0.2% at 30 days after germination) highest numbers of tillers per meter square at 30 and at 30 DAS recorded in T2 while at 90, 120 and at harvest highest number of tillers/m² recorded in T8. Numbers of effective tillers/m² and No. of grains/spike and grain yield was absorbed in T8 while wheat test weight was recorded in T2 (recommended dose of fertilizers).
