Nano PGR is a multifaceted field and has vast application in all spheres of life. But in agriculture the application and utility islimited. Use of nano PGR can assist to tackle these issues to some extent. by bieng more efficient and have longer lasting nutrient release and a higher water holding capacity reducing soil erosion, It also release multiple types of nutrient simultaneously. These nano particles are having high reactivity, better catalytic surface, rapid chemical reaction, rapidly dispersible and adsorb abundant water. The present study was conducted in the agricultural experimental farm of Calcutta University, Baruipur, 24 Parganas (south), West Bengal during winter season of 2016 and 2017 to study the “effect of various nano PGR on growth and productivity of wheat (Shriram super 252)” being conducted under slightly acidic lower gangetic alluvial region of West Bengal. The experiment was laid out in a Randomized Complete Block Design with three replications. The treatments of the experiment was T₁ was control ; T₂ = NPK @ 100:50:50 and foliar spray of green Nano PGR @ 0.5ml L^-1; T₃ = NPK @ 75:30:30 and foliar spray of Yellow Nano PGR @ 0.5ml L^-1; T₄ = NPK @ 75:30:30 and foliar spray of Red  Nano PGR @0.5ml L^-1; T₅ =  NPK @ 75:30:30 and foliar spray of Green Nano PGR @ 1ml L^-1; T₆ = NPK @ 75:30:30 foliar spray of Yellow Nano PGR @ 1ml L^-1; T₇ =  NPK @ 75:30:30 and  foliar spray of red  Nano PGR @ 1ml L^-1; T₈ = NPK @ 75:30:30 and foliar spray of Green Nano PGR @ 1.5ml L^-1; T₉ = NPK @ 75:30:30 and foliar spray of Yellow Nano PGR @ 1.5ml L^-1 ; T₁₀ = NPK @ 75:30:30 and foliar spray of Red Nano PGR @ 1.5ml L^-1 .The recommended dose of inorganic fertilizer was 100:50:50 and 75:30:30 of N, P₂O₅ and K₂O kg ha^-1respectively.All the yield attributing characters showed that the usage of different doses of green nano PGR through foliar application has positive effects compared to yellow and red nano PGR and the lowest was from control.
