Abstract :

The present investigation deals with the suitability of different inoculums and fertilizer application on mycorrhiza formation and initial growth of Shorea seedling .The study revealed soil inoculums are more effective than the other inoculums which gave higher shoot length value (41.34 cm),followed by root based inoculums and spore based inoculums (32.70cm and 27.11 cm) respectively over control. Root length value was also higher in soil based inoculums over control (19.21 cm), followed by root based inoculums (14.45 cm) and spore inoculums (12.09cm). The same trends were found in case of live and total mycorrhizal count because soil based inoculums become highly in infective and its viability as well as suitability are more. The interaction effects of fertilizers and compost was noticed in Shorea robusta. In soil, the increase in root length was directly proportional to the fertilizer dosages. Significantly better lengths were obtained in soil and compost Significantly better root lengths were obtained in soil and compost (2:1) without fertilizer (33.6cm). In soil and compost (1:1) root length were poor and showed no significant differences at different fertilizer dosages though the tendency for increases in root length was observed at higher fertilizer dosages. The result in Table–3 shows that addition of compost to soil (1:1) was not significant in Shorea robusta, addition of two part of soil and one part of composed soil (2:1) significantly improved shoot heigth (12.9cm) in Shorea robusta. Addition of fertilizer at dosages 1N and above increased shoot height though such increase was significant only at 1N (14.6cm) and 4N levels (14.5cm) in Shorea robusta.The result shows that mycorrhizal development and dry weight of seedling was best in 1/2 normal NPK (63.75%) and moderate (26.60%) in 1/4 normal NPK and in treatment without Phosphrus (22.5%).
