Abstract

Rhizobium, VAM and rock phosphate inoculation has a significant utilization in Pisum sativum.The present study was conducted to study the influence of rock phosphorus fertilization, Vesicular Arbuscular Mycorrhizae (VAM) and rhizobium inoculation on growth and yield parameters of Pisum sativum. The experiment was laid out in randomized complete block design during summer season at the Department of Botany University of Peshawar Pakistan. A composite soil sample was collected for analysis of soil for physical and chemical properties. Rock phosphorus fertilization, application along with AMF and rhizobium inoculation increased the growth parameters significantly. Inoculation under Phosphors deficient soil which have pivotal role in the mycorrhization, growth and productivity. Dual inoculation, Rhizobium and AMF resulted in an increase in grain yield respectively, over no inoculation in Pisum sativum. Maximum growth was observed where AMF along with rhizobium and rock phosphate inoculation were applied. It is concluded that Pisum sativum should preferably be grown with dual inoculation of VAM along with rhizobium and rock phosphate. And vesicular arbuscular mycorrhizal spores in the rhizospheric soils of Pisum sativum at three different stages,vegetative, flowering and fruiting highest spores density recorded at fruiting stage and increased with the age of plant and also effected by the treatment highest in dual inoculation as comapared to single inoculation.
