The influence of common bean mosaic virus infection on nodulation and
nitrogen fixation by mungbean [Vigna radiata (L.) Wilczek] was studied. The
virus infection delayed the nodule formation on secondary roots. The virus
infection decreased the nodule number, nodule size, nodule fresh weight but
increased the percent dry matter. The values of aforesaid parameters were more
in soil grown plants than in sand grown. The virus infection enhanced the
contents of total nitrogen, nitrate nitrogen, nitrite nitrogen, protein, but
decreased the ammoniacal nitrogen, carbohydrate fractions, organic carbon, C:N
ratio, leghaemoglobin, bacterial population in nodule and media. [ASJ

The effects of different levels of nitrogen (U, 5b, 112, 168, 224, 448, 672
and 784 mg/I) nutrition and Rhizobium on multiplication and symptom expression
of common bean mosaic virus kCBMV) in mungbean cv. Pusa Baisakhi were studied.
The virus activity was higher in Rhizobium-untreated than in Rhizobium-treated
plants. The increase in the virus activity was associated with an increasing
supply of nitrogen (from 0 to 784 mg/I). In Rhizobium-treated and
Rhizobium-untreated plants, the most severe virus symptoms were observed at 168
and 224 mg/l of nitrogen supply, respectively. The nitrogen level (784 mg/i)
which produced the maximum virus activity did not increase the symptom severity
in the host plants. Symptoms appeared earlier in Rhizobium-untreated than in
Rhizobium-treated plants. [AS]

Virus infection increased the uptake of nitrogen and phosphorus, but
decreased those of potassium, calcium, magnesium and sulphur. In Rhizobium
treated diseased (RD) plants the uptake of nitrogen and phosphorus was lower
than in the Rhizobium untreated (D) ones. However, the uptake of potassium,
calcium, magnesium and sulphur was higher in Rhizobium treated plants than
those of Rhizobium untreated ones. The uptake of nitrogen by healthy (H and RH)
as well as diseased (D and RD) plants of both the groups increased with
increasing nitrogen levels from 0 up to 784 ppm of nitrogen. The uptake of
phosphorous by diseased plants increased with increasing nitrogen levels from 0
up to 784 ppm but by healthy plants (H and RH) from 0 up to 224 ppm of
nitrogen. The uptake of potassium by Rhizobium treated and Rhizobium untreated
plants increased from 0 up to 56 ppm of nitrogen but declined thereafter, while
the uptake of calcium, magnesium and sulphur increased from 0 up to 168 ppm in
Rhizobium treated and from 0 up to 224 ppm in Rhizobium untreated plants. [AS]
