Studies on the effect of zinc, iron, and FYM on growth, yield and quality improvement in timely sown wheat (Triticum aestivum L.) varieties

Abstract

An experiments on “Studies on the effect of Zinc, Iron, and FYM on growth, yield and quality improvement in timely sown wheat (Triticum aestivum L.) varieties”. was conducted during Rabi seasons of 2015-16 and 2016-17 at Students’ Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh, India, situated at 125.9 meter altitude, 26.41480 North latitude, 80.23210 East longitude. The experiment consisted three varieties (PBW 550, DBW 17 and K 402), two FYM levels (FYM @10 t ha-1 and without FYM) and three nutrient management treatments (NPK- 150:60:40 kg ha-1 only, NPK+ ZnSO4 @ 25 kg ha-1 as basal + FeSO4 1% sprayed at tillering stage, NPK + ZnSO4 @ 25 kg ha-1 as basal + FeSo4 1% sprayed at flag leaf stage). The treatments were accommodated in Split-Split Plot Design with three replications. The soil of experimental field was sandy loam in texture having low organic carbon (0.36 %), medium in available Nitrogen (174 kg ha-1) low in available Phosphorus (14.0 kg ha-1), medium in available Potassium (154.0 kg ha-1), low in available Zinc (0.68 mg ha-1) and normal in available Iron (8.42 mg ha-1) with normal PH (7.92). Pooled results of two years experimentation indicated that highest value of grain yield (5017.6 kg ha-1), grain zinc concentration (41.70 ppm) and grain Iron concentration (48.82 ppm) was recorded under the variety K 402. Application of FYM @10 t ha-1 + NPK (150: 60: 40 kg ha-1) recorded maximum grain yield (4678.51 kg ha-1), grain zinc concentration (41.21 ppm) and grain iron concentration (47.15 ppm), compared to without FYM treatment. Application of NPK @ (150:60:40 kg ha-1 + ZnSO4 @25 kg ha-1 as basal + FeSO4 1% sprayed at tillering stage recorded highest grain yield (4805.69 kg ha-1), grain zinc concentration (42.03 ppm) and grain iron concentration (47.88 ppm) and compared to other nutrient management treatments. The interaction effect of varieties, FYM levels, and nutrient management treatments were found non-significant.
