to evaluate the effect of drought stress, biofertilizer and chemical phosphorus fertilizer on yield and seed protein percentage of two lentil cultivars, an experiment was conducted in split factorial based on crbd design with 4 replications in research farm of university of tehran (karaj-iran) during 2009-10. the main factor including three irrigation levels (irrigation after 70, 90 and 130 mm ...
In order to investigate the effect of Pseudomonas fluorescence strain 93 bacteria and Glomus esculentum fungus on quantitative and qualitative yield of two forage corn cultivars, an RCBD based factorial field experiment with three replications was conducted at the Agricultural Research Station of the University of Guilan in 2008. Treatments were considered as phosphorus chemical fertilizer, se...
in order to evaluate the effect of using zinc granulated phosphorous biofertilizer on yield and yield components of white bean (phaseolus vulgaris l.), a field experiment based on a randomized complete block design with three replications was performed. experimental treatment were included of using phosphate and triple super phosphorous chemical fertilizer at five levels (without using of chemi...
Drought stress is one of the most important factors affecting plant growth. Plant growth under drought stress may be enhanced by the application of microbial inoculation including plant growth promoting rhizobacteria. This research was conducted as a factorial experiment in a completely randomized design. The first factor included the bio-fertilizer (A. vinelandii (A)), P. agglomerans+ P. ...
