Effects of chemical fertilizers and biostimulantscontaining amino acid on yield and growth parameters of broad bean (Viciafaba L.)

ABSTRACT:Application of biological fertilizers is a promising approach in reducing environmental pollution and achieving sustainable agriculture. In order to evaluate effect of chemical fertilizers and biostimulants containing amino acid on yield and growth properties of broad bean, the experiment was carried out as completely randomized block with three replicates in 2012. The treatments including 1) NPK151500 ppm, 2) NPK153000 ppm , 3) NPK20 1500 ppm, 4) NPK20 3000 ppm, 5) Humiforte (H) 1500 ppm, 6) H 3000 ppm, 7) Fosnutren (F) 1500 ppm, 8) F 3000 ppm, 9) Kadostim (K) 1500 ppm, 10) K 3000 ppm and 11) control. Results of the experiment indicated that number of pods in shrub, affected by above treatments at 1% of probability level, while number of flowers in shrub, yield in shrub and total yield affected by the treatments at 5% of probability level. It was no significant difference among treatments for length of pods, number of seeds in pod, weight of single pod, 1000-seed weight and plant height. The highest number of pods in shrub and number of flower in shrub was in K 3000 ppm.
