“…On PDA plates, A. niger colonies are large, thick, globose, and dark brown in appearance. As they approach the vesicle, conidiophores have smooth walls, are hyaline, or darken (Romero‐Cortes et al., 2019). The phialides are brown, usually septate metulae, with biseriate conidial heads (Exhibit 5).…”

Phosphorus (P), the second most essential nutrient, plays a remarkable role in energy transfer, storage, plant growth, and development. It is the least mobile and accessible to plants in most soil conditions as compared to the other key nutrients. Phosphate‐solubilizing fungus (PSF) plays a vital role in supplying phosphorous to plants from the soil. Hence this research intends to assess the phosphorous and nutritional status of collected soil samples as well as isolation of potential fungal strains. Twelve soil samples were taken from three costal districts of Odisha (Bhadrak, Jajpur, and Balasore). All six key soil parameters like pH, electrical conductivity, organic carbon, nitrogen, phosphorous, and potassium were examined for correlation and found to be significantly associated with each other. Fungal colonies were enumerated, grown and pure colonies were found. A total of four potential fungal strains were isolated, screened from rhizospheric soil and evaluated for their phosphate solubilization efficiency on Pikovskaya's agar selective media. They produce the halo zones around their colony approximately 3.3 cm (PRF2), 2.96(PRF3), and 3.06(PRF4) cm within 10 days of incubation. Aspergillus niger was a highly efficient strain in solubilizing phosphate with the solubilization index (SI) of 3.56 cm and also showed the greatest drop in pH in the PVK broth containing rock phosphate.

Trichoderma spp. is a fungus widely used to control soil-borne pathogens, such as Rhizoctonia solani which is plant pathogenic fungi in widely host range, especially on rice. This research aimed to evaluate the ability of Trichoderma asperellum isolate UGM-LHAF against R. solani causing sheath blight disease of rice in vitro condition. Trichoderma sp. used in this research was obtained from The Biological Laboratory of Pakem, Yogyakarta, Indonesia, and Rhizoctonia sp. was obtained through isolation of diseased rice obtained from rice fields in Yogyakarta. The two isolates were characterized base on morphology and molecular identification based on ITS rDNA. The pathogenicity test of Rhizoctonia sp. was evaluated by adding four sclerotia of Rhizoctonia sp. near rice roots at 6 days after sowing. The in vitro test used dual culture and antifungal activity (0%, 10%, 25%, 50% culture filtrate of Trichoderma sp.) with three replicates of each treatment. Two isolates were identified as T. asperellum and R. solani. Sheath blight symptoms appeared after 12 days inoculation. In the in vitro test, T. asperellum isolate UGM-LHAF was able to inhibit the mycelial growth of R. solani (64.23% on dual culture and 68.5% on antifungal activity). This study suggests that T. asperellum isolate UGM-LHAF able to inhibit the growth of R. solani and can be a further potential candidate as a biocontrol agent against R. solani causing sheath blight disease of rice.

“…DNA extraction of JCP1 and JCP2 strains was performed as described by Cuervo-Parra et al [ 24 ], where a region of nuclear DNA from each strain (containing the ITS sequence) was amplified by PCR, using the primers ITS5 and ITS4B [ 25 ]. The PCR amplifications were performed as described by Romero-Cortes et al [ 26 ]. Pairwise sequence alignments were performed with the online BLAST program, with sequences from the NCBI database [ 27 ].…”

Globally, corn is the most economically important crop, surpassing other cereals of economic importance. However, the tillage methods, monoculture and the abuse of synthetic agrochemicals used in Mexico have led to the loss of fertility and soil yield. In this sense, the application of alternative fertilization methods based on chemical fertilizer, organic matter and biofertilizer, applied alone or in combination, can stimulate the defense systems of corn plants and increase their yield. Therefore, in this research, some fertilization schemes were tested on purple corn plants of the Kculli race through the evaluation of some growth and yield variables, as well as the subsequent evaluation of the chemical characteristics of the corn grain produced in each fertilization scheme. The results indicate highly significant differences (p ≤ 0.05) between treatments, for the different growth and yield variables studied. Of all the fertilization schemes evaluated, treatment T7 obtained the best grain yield of 6.19 ± 0.07 t ha−1, with respect to treatment T1 of 1.02 ± 0.01 t ha−1, as well as the highest protein content and starch quality. Being clear the positive effect of the adequate contribution of the macro and micronutrients used exerts on the corn crop in each of the fertilization schemes studied. On the other hand, the analysis carried out on the grains was found within the values reported by other authors.
