A pot experiment was laid out at Sri Karan Narendra College of Agriculture, Jobner in 2015 during kharif season using cowpea as a test crop to study the influence of soil salinity, phosphorus sources and biofertilizers on yield and total nutrient uptake by cowpea (Vigna unguiculata L.). The experiment was tested in completely randomized design in which three levels of each salinity (EC 1.22, 4.0 and 6.0 dS/m), phosphorus (single super phosphate, di ammonium phosphate and phosphorus rich organic manure) and biofertilizers (control, phosphorus solubilizing bacteria and phosphorus solubilizing bacteria + vesicular arbuscular mycorrhiza) were used with three replications. The experimental data showed that soil salinity (EC 1.22 dS/m) recorded significantly higher yield and total nutrient uptake by cowpea in comparison to other treatments. But nitrogen content lowest recorded at EC 1.22 dS/m. Result further revealed that phosphorus source phosphorus rich organic manure recorded significantly maximum yield and total nutrient uptake by cowpea over rest of the treatments. Furthermore, seed inoculation with phosphorus solubilizing bacteria + vesicular arbuscular mycorrhiza recorded the maximum yield and nutrient uptake by cowpea over rest of the treatments. It’s concluded that combination of EC 1.22 dS/m + phosphorus rich organic manure + Biofertilizers (phosphorus solubilizing bacteria + vesicular arbuscular mycorrhiza) found superior in all these parameters over the control.

Mycorrhizal Plants

Plant growth and physiological response of sesame (Sesamum indicum L.) were studied in controlled environment using normal soil and indigenous Vesicular-arbuscular mycorrhiza (VAM) fungi treated soil. The seedlings of Zea mays were inoculated with Giguspora species of VAM (Glomus fasiculatum) and the inoculum was multiplied with help of Zeamays seed bed. Sesame seeds were then inoculated into the bed and it was found that the plant height, shoots lengths, roots, biomass of shoot and roots were considerably increased in the mycorrhizal plants. The effect of VAM infection was assessed in pot experiment. In this comparative study, specific mycorrhizal fungi had consistent effects on various growth parameters such as the number of leaves, number of roots, shoot length, biomass of shoot and roots and biochemical parameters were observed at various time intervals by statistical analysis using two way ANOVA, it was confined with mycorrhizal and non-mycorrhizal infected plants. It was found that the ability of isolates to maintain the plant growth effectively in the case of mycorrhizal seedlings shows a maximum absorbtion of 0.77 ±0.2, shoot length is about 8.34 ±0.2, count of root and leaves are about 8.10 ±0.3, 5.6 ±0.3 respectively under mycorrhizal infection in 30days of analysis and had a positive effect on the growth at all intervals. Biochemical analysis were carried out to estimate the total chlorophyll, chrophyll A, chlorophyll B and Carotenoids contents and it was analyzed to be 9 ±0.5 mg/g, 8.3 ±0.5 mg/g, 3.6 ±0.5 mg/g, 4 ±0.3 mg/g respectively. At the 30th day of analysis for the mycorrhizal plants, it was found to be high in mycorrhizal seedlings which shows the symbiosis had improved the nutrient uptake of cultivated plants. Nevertheless G. fasiculatum was found to be the most efficient fungus and exhibited the highest levels of mycorrhizal colonization, as well as the greatest stimulation of physiological parameters.
