The Impact of Biological and Chemical Phosphate Fertilizer on Some Morphological Traits and Green Cover Percentage of Moldavian Balm
Journal Title: International Journal of Farming and Allied Sciences - Year 2016, Vol 5, Issue 5
Abstract
A split plot experiment (using RCB design) with three replications was conducted in order to study the effects of phosphate (P) bio-fertilizer (Barvar2; Bacillus lentus + Pseudomonas putida) in tow forms as seed inoculation and topdressing and chemical P fertilizer (0, 3.75, 7.5, 11.25 and 15 g m-2 of triple superphosphate) on some morphological characteristics and green cover percentage of Moldavian balm. Result revealed that application of the P bio-fertilizer as seed inoculation and topdressing increased green cover percentage (GCP) under all levels of chemical P fertilizer. Maximum plants height was recorded in the P bio-fertilizer as seed inoculation under 11.25 g m-2 of triple superphosphate (P3). Maximum number of secondary branches and stem day weight were obtained from P bio-fertilizer as topdressing treatment at level 7.5 g m-2 of chemical P fertilizer (P2). The highest leaves and flowers dry weight were also recorded for plants under P2 treatment. It is concluded that under low levels of chemical P fertilizer (P1 and P2), with application of P bio-fertilizer as topdressing GCP, plant height, number of secondary branches and stem dry weight were strongly improved. However, under high levels of chemical P fertilizer (P3 and P4), seed inoculated plants with P biofertilizer had more of those traits.
