Abstract: Macronutrients are essential for the growth and good overall stage of the plants. They play a very important role in the plant growth and development. Moreover these elements must be present in the proper proportion. Their function ranges from being structural units to redox sensitive agents. The supply of boron to the plants play key role in behaviour of other macro and micro nutrients in the plant. The response of plants to boron varies with soil type, environmental conditions and plant species also. So the excess or deficiency of boron may affect the uptake and availability of other plant nutrients. The sweet Sorghum is a semi-arid crop grown as main staple food of many areas. It is also used as fodder, fuel and fertilizer. The sweet Sorghum c. v. Madhura was selected for the present investigation. In the present investigation the effect of different boron concentrations like 0 ppm (Control), 10 ppm, 50 ppm and 100 ppm on sweet Sorghum var. Madhura has been studied. The pot culture technique was used for this investigation. The objective was to identify the correct dose of boron to improve behaviour of some macronutrients in sweet Sorghum. The data was collected after the fifth day of last treatment of boron. In the present investigation, an attempt was made to study the influence of boron on the behaviour of macronutrients like N, P, K, in the sweet Sorghum cultivar Madhura. Our results clears that boron increases nitrogen in plants benefitted to nitrogen metabolism under boron stress conditions through nitrogen metabolism for the improvement of crop. The induced nitrogen content might enhance uptake of mineral elements such as P, K, Ca, Mg, Zn, Mn as indicated by Moussa (2000). The increase of P under increasing boron concentration suggests a promoted remobilization of P in Sorghum. The adaptive nature of accumulation of K+ due to boron treatments reported in c. v. Madhura, which correlates, with many earlier reports and it might be helpful to regulate metabolic activities in the c. v. Madura.
