Abstract

A field trial was carried to find out the efficacy of different doses of zinc on growth, yield attributes and nutrient uptake in rice during the years 2017 at the Breeder Seed Production Unit (Soybean) of Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh. The experiment consists of three main treatments as different rice varieties and five sub treatments of different concentration of Zn which were replicated three times in a split plot design.. The main treatment consist of V1: Kranti,V2: MTU1010 and V3: PS 5 and sub plot 5 treatments consist of T1: 100% NPK + No Zn (control), T2: 100% NPK + 0.25% ZnSO4 ha- 1 (foliar spray) at 30 and 60 DAT, T3: 100% NPK + 0.50% ZnSO4 ha-1 (foliar spray) at 30 and 60 DAT, T4 :100% NPK + 0.75% ZnSO4 ha-1 (foliar spray) at 30 and 60 DAT, T5 :100% NPK + 25 kg ZnSO4 ha-1 (soil application). All the growth attributing characters such as (plant height, dry matter accumulation in shoot and root and number of tillers hill-1) were studied
