Endophytic isolates of Trichoderma viride and T. pseudokoningii from black pepper caused 64.4 and 65.6 per cent inhibition of mycelial growth of Phytophthora capsici in vitro. In planta screening showed that the isolate of T. viride was efficient in reducing Phytophthora rot incidence and enhancing plant growth characters. In pot and field experiments also this isolate resulted in the lowest infection by the pathogen.Keywords

A study was undertaken to determine the presence of aflatoxigenic fungi and other fungal contaminants in the kernel, mace and shell of ripened nutmeg tree fruits collected from nutmeg plots of Ernakulam and Thrissur districts of Kerala. Mace and nut were separated from fruits and washed in tap water to remove soil particles and other debris adhering to it. The kernel, mace and shell were subjected to different chemical/botanicals by four methods viz; dipping, decoction, samples in cloth bag and fumigation in order to prevent aflatoxigenic fungi and other fungal growth during storage. Based on the present studies, it was found that pre-treatment of kernel, mace and shell of nutmeg with either citrus leaf decoction (@100 g/litre) or curry leaf decoction (@ 100 g/litre) or Anona seed extract (5%) using decoction method were effective against aflatoxigenic fungi as well as fungal contamination. However, further studies are needed on pilot scale to confirm.Keywords

Proximate and anti-nutrient composition of leaves, young shoots, flowers and pods of Moringa were analysed. The KAU released Moringa variety Anupama were selected for analysis. High moisture content of more than 80 % was observed in all parts of Moringa. Leaves had a high moisture content of 85.4%. The protein content was high in young shoots (6.12 g) followed by flowers (4.9 g), leaves (4.37 g) and pods (2.8 g). A high beta carotene content is present in leaves (16265 μg) followed by young shoots (13841 μg), pods (15.62 μg) and flowers (3.25 μg). Fat content of > 0.18 g was observed in all parts of Moringa. Leaves had a high vitamin C content of 53 mg followed by 62.76 mg in pods, 43 mg in young shoots and 7.25 mg in flowers. The calcium content was high in leaves (208 mg) followed by young shoots (123 mg), flowers (38 mg) and pods (24.5 mg). A high iron content of 5.12 mg is present in leaves, 3.90 mg in young shoots, 0.33 mg in flowers and 0.329 mg in pods. Leaves had a high phosphorous content of 95.1 mg followed by 73 mg in young shoots, 66.2 mg in flowers and 46.9 mg in pods. The zinc content was high in flowers (0.342 mg) followed by young shoots (0.30 mg), pods (0.268 mg) and leaves (0.23 mg). Anti-nutritional factors like phytates (18.7 mg), oxalates (15.7 mg) and tannins (0.311 mg) were high in leaves and pods.Keywords

To ascertain the impacts of flood-affected and landslide-impacted soils on the microbial community and soil nutrient status, an assessment between disturbed and undisturbed soils was conducted. Without discernible differences between soils impacted by flooding and landslides, the total bacterial and fungal population had decreased in disturbed soils. The lack of organic carbon and copper in flood-affected soils profoundly impacted the bacterial population. The disturbed soils were found to have reduced organic carbon, nitrogen and micronutrients. The microbial isolates that persisted even in these degraded conditions may be considered potential bioagents for the restoration of disturbed soils.Keywords
