Abstract
To evaluate the effect of Zinc fertilizer on performance of wheat cv. BARI gom30, an experiment was carried out at Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, from November 2015 to March 2016. The experiment comprised four levels of Zinc (Zn) viz., 0, 1.5, 2 and 2.5 kg/ha. The experiment was laid out in a randomized complete block design with three replications. Application of Zinc (Zn) plant height, number of total tillers/plant, number of effective tillers/plant, spike length, number of fertile spikelets/spike numbers of sterile spikelets/spike number of grains/ spike, grain yield and straw yield were found significant. But there was no significant effect of the treatment on 1000-grain weight. The highest number of total tiller/plant (4.42), number of effective tillers/plant (3.92), number of grains/spike (47.70), 1000-grain weight (47.73 g), grain yield (5.06 t/ha), straw yield (6.21 t/ha) was obtained from 2 kg Zn/ha. The highest plant height (94.08 cm), spike length (9.92 cm), number of fertile spikelets/spike (19.59) and sterile spikelets/spike (3.22) and harvest index (46.16%) were recorded at 0 kg Zn/ha respectively. The control treatment indicated the lowest value for the yield attributing characters except the number of sterile spikelets/spike. Grain yield was found to be significantly and positively correlated with number of grains/spike and straw yield. It is recommended that application of 2 kg Zn/ha is the best for maximum yield of BARI gom30.  Â
Highlights
Wheat (Triticum aestivum L.) is the most important cereal crop of the world
According to Brown et al (1993) formation of male and female reproductive organs and pollination process are disturbed in Zn deficiency which may be attributed to the reduction of Indol acetic acid (IAA) synthesis
Zinc plays an important role in completing the life cycle of plants and a key role in nitrogen metabolism, photosynthesis and toxin synthesis
Summary
Wheat (Triticum aestivum L.) is the most important cereal crop of the world. It ranks first both in area and production. Chlorophyll, metabolism of starch formation and enzyme carbonic anhydrase accelerating carbohydrate formation, the maximum requirements Zn were enough to accumulate suitable carbohydrate contents It activate glutamic dehydrogenase enzyme, synthesis of RNA and DNA enhancing gliadin and glutenin content, which are main protein components of gluten accumulated in the later stages of grain filling. Initiation of primordial structures at reproductive phase occurs as a result of favourable effect of zinc on the metabolic reactions within the plants. It should be used in correct doses for increasing soil fertility and to boost crop yield. Considering the above importance of Zn in wheat cultivation, the research work was undertaken to examine the effect of Zn micronutrient on the performance of BARI gom
