The effect of sulphur and foliar manganese applications on soybean (Glycine max l.) yield and its main component [electronic resource].

Includes references.

TWO FIELD trails were carried out at Shandaweel, Agric. Res. Station, during the growing seasons 1999 and 2000 to evaluate the effect of different applications of sulphur (0, 60, 90 and 120 kg. sulphur /fed.) and manganese foliar (0, 200 and 400 g Mn/fed.) on yield , nodulation, plant growth, nitrogen %, protein content, phosphorus%, oil % and potassium % of soybean (Glycine max L.). The spilt plot design with four replications were used , sulphur treatments were in the main plots and manganese foliar applications in the sub-plots. The response to treatment varies with the levels of sulphur and manganese foliar application. The interaction effect between Sand Mn-foliar was significant effect on dry matter yield (g/plant), number of branches, nodules number/plant and seeds yield (kg/fed.). The highest value of N ,P,K content and consequently protein content and oil percent was obtained in the treatment received the highest levels of Sand Mn. On the other word, it can be recommended to add 90 kg S/fed. and 400 g Mnlfed. to produce the highest rate of soybean seeds/fed.
