 ABSTRACT

A field experiment was conducted in the Department of Horticulture, Khalsa College, Amritsar during 2017-18 to study the Effect of pre-harvest foliar application of macro and  micro-nutrients on fruit growth, yield and quality of tomato (Lycopersicon esculentum Mill.) cv. NS-524. The investigation was laid out in Randomized Block Design (RBD) with three replication having ten treatments viz., potassium sulphate (0.50 %. 0.75 %, 1.00 %), zinc sulphate (200 ppm, 300 ppm, 400 ppm), boric acid (200 ppm, 300 ppm, 400 ppm) and control (water). The foliar spray was given at three stages first at 30 (DAT), second at 40 (DAT) and third at 50 (DAT). Potassium sulphate application at 0.75 % showed minimum days to 1st flowering (30.41) and fruiting (51.95), maximum number of flower per plant (45.53), number of cluster per plant (6.93), number of fruit per plant (28.70), TSS (5.65ºBrix) and ascorbic acid (16.23 mg/100g). In case of micro-nutrients boric acid and zinc sulphate @ 400 ppm showed better results over the other concentrations viz. more effective in increasing flowering and bio-chemical characters. Therefore, the foliar application of potassium sulphate at 0.75%, boric acid at 400 ppm and zinc sulphate at 400 ppm are the most effective treatments can be used alone to improve flowering and bio-chemical character of tomato.

Keywords: Potassium sulphate, Boric acid, Zinc suphate, Tomato, NS-524.
