Combined Efficacy of Macro-Nutrients and Micro-Nutrients as Foliar Application on Growth and Yield of Tomato Grown By Vegetable Forcing

The present research project was executed during 2008–2009, to evaluate the effect of Zn, B (micro-nutrients) in combination with N (macro-nutrient) for the tomato grown under high tunnel. Macro/micro-nutrients solutions were provided by 4B Group of Fertilizers Pakistan. The experiment was arranged in Completely Randomized Design (CRD) with five treatments with four replications. Foliar application of individual nutrients such as N (2%), B (5%) and Zn (6%) were used along with their combined mixture. In addition, a control treatment was also run as check. After the statistical analysis it was found that individual application of nutrient provide better results as compared to control but their combined effect (Zn = 6%, B = 5%, N = 2%) provided substantial results in plant heights, no. of leaves, no of flowers, no of fruits, average fruit weight and yield per plant. It is confirmed from the results that combination of macro-nutrients and micro-nutrients as foliar application has the ability to enhance the growth and yield of tomato positively.
