EFFECT OF DIFFERENT SOURCES AND LEVELS OF BORON ON SOIL PROPERTIES AND UPTAKE OF NUTRIENTS IN TOMATO (Solanum lycopersicum)

The present study was conducted to determine the effect of boron on soil properties and uptake of nutrients. Boron was applied through three different sources viz., borax applied as soil application; boron metalosate and boric acid supplied through foliar spray. The results revealed that application of boron significantly promoted the uptake and properties of soil. Soil pH, EC, OC, Iron (Fe), Manganese (Mn) and Copper (Cu) were did not differed significantly due to application of different sources and levels of boron whereas application on boron on available nitrogen, available phosphorus, available potassium, available sulphur, exchangeable calcium and exchangeable magnesium content of soil after the harvest of tomato differed significantly .The highest uptake of nitrogen (177.32 kg ha-1), phosphorus (30.85 kg ha-1), potassium (134.09 kg ha-1), calcium (82.08 kg ha-1), magnesium (51.03 kg ha-1), sulphur (54.66 kg ha-1), iron (607.97 g ha-1), manganese (349.54 g ha-1), copper (89.57g ha-1), zinc(199.84 g ha-1) and boron (209.59 g ha-1) were recorded in in T10 treatment which consists of NPK+ FYM + 1.1 kg ha-1 B through borax as soil application + 0.05% B through boron metalosate as foliar application
