Rot Disease

This study aimed to isolate and identify Macrophomina phaseolina fungus which was the causal aget of Charcol rot disease on mung bean (Vigna radita Wilczek L) from Elgadisia Governorate in order to isolate, diagnose, and evaluate efficacy of biological control fungal agents isolalated from the rhizosphere of the host plant. The biocontrol agents T. koningii, C. globosum and A. carbonarius were effective in inhibiting the pathogenic fungus under laboratory and greenhouse conditions. Two isolates of M. phaseolina fungal pathogen were identified in most samples of infected mung bean. Pathogenicity tests showed the ability of M. phaseolina to attack the seeds and cause seed rot. Isolates 1 and 2 of the fungal pathogen reduced the seed germination rate to 71.56 and 63.75%, respectively, compared with 86.66% for the control. The results obtained indicated the presence of a significant difference between the two isolates in inducing seedlings damping-off which reached 40% and 30%, respectively, compared with 0% for the control. The disease severity of isolate 1 reached 75.3% and that of isolate 2 reached 63.6%. The inhibitory effect of the fungal antagonists T. koningii and C. globosum varied. A. carbonarius demonstrated level 3 of inhibition to the pathogenic fungus M. phaseolina, whereas C. globosum and T. koningii demostrated inhibitory levels of 2 and 1, respectively. Results obtained also indicated that treatments with antagonistic fungi T. koningii, C. globosum and A. carbonarius increased the growth parameters of the mung bean plant. The antagonistic fungus C. globosum increased the plant height, root fresh and dry weight and chlorophyll content compared with the control. Furthermore, the results showed that treatment with T. koningii increased the mung bean seed germination rate to 100% and decreased disease severity of mung bean charcoal rot disease to 45.88% as compared to 89.86% severity for the contol. Likewise, the other antagonistic fungi A. carbonarius and C. globosum also increased the mung bean seed germination , and decreased mung bean charcoal rot disease severity.

Early Seedling

Abiotic stress such as drought and agrochemicals leads the drastic reductions in legume yields, hence, in order to mitigate the loss of yields due to abiotic stresses, the production of stress tolerance genotypes of the legumes could be a rewarding approach. Therefore, the aim of the present study was to evaluate the drought and herbicide stress effects under ex-vitro conditions on seed germination and early seedling growth in a legume crop mung bean (Vigna radiata L.). To begin with, drought stress was induced by employing various concentrations of mannitol (50mM, 100mM, 250mM, 500mM, 750mM, and 1000mM) and polyethylene glycol (PEG-5%, 10%, 15%, 20%, and 25%) while during herbicide stress experiments, dicamba (3,6-dichloro-2-methoxybenzoic acid) and picloram (4-Amino-3,5,6-trichloro-2-pyridine carboxylic acid) were considered in various concentrations (5mg/L, 25mg/L, 50mg/L, and 100mg/L) of each. Moreover, data were collected as partial and full seed germination after 3- and 7-days of stress treatments respectively. After 7-days of mannitol stress treatments, results reveals that even the high concentration of mannitol (500mM) could be proved as weak osmotic stressor for seed germination (35%±0.14) in comparison to control (91%±0.74) while further increase in mannitol concentration (750mM) was proved to be lethal, toxic and inhibits seed germination completely. Furthermore, in comparison to mannitol, PEG turns out as strong osmotic stressors and (15%) of PEG was proved to very lethal for seed germination. Even during early seedling growth, increased concentrations of both mannitol and PEG were found to be inhibitory. Among two herbicides, the result shows that both herbicides (dicamba and picloram) were proved to be completely toxic and lethal even at very low concentrations (5mg/L) and induced abnormal seed germination and inhibited completely seedling growth. However, the inhibitory response of picloram herbicide stress on seed germination was found to be more pronounced and severe than dicamba herbicide. Hence, the present study reveals that in comparison to mannitol, PEG turns out as a strong osmotic stressor while picloram proves to be a relatively more toxic herbicide than dicamba for seed germination. Additionally, drought stress induced seedlings on transfer to soil exhibit inhibited growth under continuous irrigation with either mannitol or PEG solutions.

Currently, a real challenge for the workers in the agricultural research field is to stop or reduce the use of expensive agrochemicals/ chemical fertilizers which are hazardous to the environment as well as human health. Present study was aimed to improve the growth and obtain optimum yield of Vigna crop with eco-friendly, non-toxic way and to reduce the use of agrochemical/chemical fertilizer application in agricultural activities. A pot experiment was conducted to study the effect of chemical fertilizer (DAP) and biofertilizer ( Rhizobium strain) separately and in combination on seed germination and seedling growth (at 30 days) based on morphological parameters such as seedling length (cm), fresh weight (g), dry weight (g) and leaf area (cm)2 of Vigna radiata (L.) Wilczek. After one month (30 Days) observations, it was found that seedling length, fresh and dry weights and leaf area were maximum in T4 and minimum in T15, T7 and T8 favored improved seedling length and leaf area whereas T7, T8, and T9 favored improved fresh and dry weights as compared to control.
