Abstract
The present investigation was conducted during rainy (kharif) season of 2017 at the Agricultural Research Farm of Rajiv Gandhi South Campus, Banaras Hindu University, Barkachha, Mirzapur. The experimental area falls under semi-arid to sub-humid climate and the experiment was laid out under rainfed situations and the soil of the experimental field was sandy clay loam in texture, well drained and medium acidic soil reaction (pH 5.4). It was moderately fertile, being low in organic carbon (0.28%), low in available nitrogen (202.36 kg ha-1), and medium in available phosphorus (19.55 kg ha-1) and medium in available potassium (235.75 kg ha-1). The factorial experiment was layout in Randomized Block Design with three replications. The experiment comprises 12 treatment combinations of three foliar application of zinc levels (F1: control, F2: 0.1% and F3: 0.5%) and four soil application of zinc levels (S1: control, S2: 5 kg ha-1, S3: 10 kg ha-1 and S4: 15 kg ha-1). Looking to the result of the present study, application of 15 kg ha-1 Zn produced highest grain yield among all soil applied Zn treatments. However 0.5 % foliar application of Zn gave higher grain yield than 0.1 % foliar application.
