Abstracts |
The effects of VAM [vesicular arbuscular mycorrhiza] (0, 125 or 250 g/ha), singly or in combination with P (0 or 60 kg P2O5/ha), on the performance of soyabean (cv. JS 335) were studied in Jabalpur, Madhya Pradesh, India, during the rainy seasons of 1997 and 1998. Dry matter accumulation and crop growth rate increased until maturity, whereas LAI [leaf area index] increased up to 60 days after sowing (DAS). NAR declined gradually until 90 DAS due to reduced photosynthesis under all treatments. The values of growth and yield parameters increased with the increase in the concentration of VAM. At 60 and 90 DAS, 60 kg P2O5 + 250 mg VAM/ha resulted in the greatest dry matter content (222.0 and 399.6 g/m2, respectively), CGR per plant (5.01 and 6.92 g/m2), NAR (2.40 and 1.09) and RGR [relative growth rate] per day (45.17 and 16.92 mg/m2). This treatment also recorded the greatest LAI at 90 DAS (7.20), plant height (67.5 cm), number of branches per plant (3.7), number of nodules per plant (34.5), number of pods per plant (32.6), and straw yield (11.3 quintal/ha).
