Crop 2020-07-10T22:33:24+00:00 M. A. Awal M. H. O. Rashid M. M. Rahman <p><strong>Background and Objective:</strong> Sulphur and boron are found as most critical nutrient elements for the better growth and yield of mustard crop however no such concrete information for their uses in field production of this crop is yet to be reported. Therefore, an experiment was conducted to investigate the effect of agronomic biofortification of sulphur and boron nutrients on the growth and yield of mustard crop.</p> <p><strong>Study Design:</strong> The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replicates.</p> <p><strong>Place of Study: </strong>The experiment was carried out in the Crop Botany Field Laboratory, Bangladesh Agricultural University, Mymensingh.</p> <p><strong>Methodology:</strong> Three doses of sulphur (S) viz. 0, 20 and 40 kg ha<sup>-1</sup> and three doses of boron (B) viz. 0, 0.5 and 1.0 kg ha<sup>-1</sup> and their possible combinations were used as basal doses. Field data were collected from periodic destructive samplings on the plant height, number of leaves and branches per plant, total dry matter accumulation and finally yield components and yield.</p> <p><strong>Results:</strong> Sulphur and boron fertilizations significantly influence the plant height, production of branches and leaves per plant, dry matter accumulation and yield attributes and yield of mustard crop. The mustard crop fertilized with 40 kg S ha<sup>-1</sup> in combination with 1 B kg ha<sup>-1</sup> produced taller plant, higher number of branches and leaves in each plant and higher amount of dry matter per plant while these plant traits were found as minimum when the growing the mustard crops in control plots i.e. the plants received neither sulphur nor boron. Application of sulphur @ 40 kg ha<sup>-1</sup> along with boron @ 1 kg ha<sup>-1</sup> produced the highest seed yield (2.73 t ha<sup>-1</sup>) whereas the lowest seed yield (1.08 t ha<sup>-1</sup>) was found where no sulphur and boron were applied.</p> <p><strong>Conclusion: </strong>The result conclude that combine application of sulphur and boron @ 40 and 1 kg per hectare, respectively was found to be most effective dose in enhancing growth and yield of mustard crop.</p> 2020-06-24T00:00:00+00:00 ##submission.copyrightStatement## Assessment of the Effects of Seasonal Flooding on the Properties of Floodplain Soils of Wukari, Taraba State, Nigeria 2020-07-10T22:33:23+00:00 A. T. Gani T. Bako A. Christopher <p>The aim of this study was to examine the effects of seasonal flooding on the properties of floodplain soils of Wukari Area of Taraba state. The treatments consisted of five different locations of Gidan-Idi, Gindin-Dorowa, Tsokundi, Rafin-Kada and Nwuko and three different soil sample depths of 0-20 cm, 20-40 cm, and 40-60 cm laid out in a completely randomized design (CRD) and replicated three times. Soil samples were collected from each plot in 2016 and 2017. All soil samples were analyzed for physical and chemical properties. The results obtained were subjected to analysis of variance and means separated using F-LSD test at p≤.05. The results of the soil properties analysis showed that some of the determined parameters were significantly different at the different sample locations at p≤.05. The soils of Wukari Floodplains are mostly clay loam in texture having very slightly acid to neutral soil reaction, moderate organic matter, low total N, moderate available P, low exchangeable bases and CEC. The flood plain soils were moderate in soil fertility, a confirmation of the general characteristic of Savanna soils. The soils were not deficient in micronutrients. Seasonal flooding had significant (positive) influence on some physical and chemical properties of the flood plains most particularly at Rafin-Kada.</p> 2020-07-04T00:00:00+00:00 ##submission.copyrightStatement##
