Effect of K Nano-Fertilizer and N Bio-Fertilizer on Yield and Yield Components of Tomato (Lycopersicon Esculentum L.)

Objective: This field experiment was laid out in order to study on effect of Nano and Bio fertilizers on yield and yield components of tomato (Lycopersicone sculentum L.) during the growing seasons 2013- 2014. Methods: The experiment was laid out in a factorial based on randomized block design with three replications. Treatments were K nanofertilizer in five levels such as (0, 100, 200, 300 and 400 kg.ha^-1) and pure Azot in five levels such as (0, 50, 100, 150 and 200 kg.ha^-1). Results: Results showed that the application of humic acid and nitrogen fertilizer were significant of all traits of tomato but effect of humic acid on fruit length was not significant. Application of 400 kg per ha K nanofertilizer had the highest plant height and stem diameter. Also results showed that application of 300 kg per ha K nanofertilizer had the highest number of fruit per plant, fruit weight, fruit diameter and fruit yield. However application of nitrogen fertilizer increased yield and yield components of tomato. In final results of the present study reviled that application of K nanofertilizer and nitrogen fertilizer increased yield and yield components of tomato.
