A set of experiments was designed to study the effect of different nutrients through foliar and/or soil application on wheat plant (Triticum aestivum L.). Different concentrations of nitrogen, phosphorus, potassium (NPK) i.e., NH4NO3, K2HPO4 and KH2PO4 were used. The effect of (NH4)2SO4 through foliar application on the same plant was also studied. The results revealed that growth and yield of the plant increased when treatment was applied either through soil or through foliar and soil together, while it decreased when treatment was applied only through foliage. The increase was more pronounced in case of collective (soil and foliar) treatment. However, there was a gradual but regular increase with (NH4)2SO4 treatment. Root length showed more or less the same effect, i.e., it increased in foliar + soil and only soil applied treatment, decreased in foliar applied treatment and slightly increased with (NH4)2SO4 treatment. The effect on grain yield was somewhat similar i.e., it increased in foliar + soil and only soil applied treatment, decreased in foliar applied treatment. However, in contrast to the effect on plant size the treatment with (NH4)2SO4 decreased the grain yield. It was concluded that treatment through soil and foliar together yield better results.
