Impact of phyto-chemicals with nutrients on growth analytical traits and yield of tomato

Author(s): Dr. R Sivakumar and Dr. S Srividhya
Abstract: Field experiment was conducted to study the impact of phyto-chemicals (naphthalene acetic acid - 20 ppm, chloro choline chloride - 200 ppm, gibberellic acid - 20 ppm and salicylic acid - 100 ppm) with nutrients nitrogen (2% urea) and phosphorus (2% mono ammonium phosphate) alone and combinations on growth analytical parameters and yield of tomato by foliar spray at 30 and 60 days after transplanting. The growth analytical parameters like leaf area index, leaf area duration, specific leaf weight, net assimilation rate and crop growth rate, and yield were estimated. Foliar spray of 2% urea with 20 ppm gibberellic acid registered higher leaf area index (0.89), leaf area duration (27 days), specific leaf weight (0.0874), net assimilation rate (0.642) and crop growth rate (16.20). However, the highest fruit yield of 33.87 t ha-1 was recorded by foliar spray of 2% MAP + 100 ppm salicylic acid followed by 2% urea with 20 ppm gibberellic acid (32.13 t ha-1).
