Effect of Biofertilizer Application on Growth Parameters of Spathiphyllum illusion

Abstract

Biofertilizers have some microorganisms which convert elements to available nutrient for plant's roots. This study was conducted to investigate the effects of biofertilizers and chemical fertilizers on growth indices of Spathiphyllum illusion. This trial was carried out in a Randomized complete block design (RCBD) in 3 replications. Treatments were: control (without fertilizer), (nitrogen biofertilizer), urea, + urea, (phosphate biofertilizer), super phosphate, super phosphate + Barvar-2, + Nitrokara. The results showed that triple super phosphate + Barvar 2 treatment resulted in increasing leaves number, dry and fresh weight of leaves and the size of spadix. Barvar-2 + Nitrokara has the best effect on leaf size, height of flower stalk and chlorophyll content. The maximum amount of absorbing nitrogen was obtained under urea application.
