“…According to Sangakkara [164], soil compaction reduces common bean yield, whereas soil tillage favours root branching and increased yield. In field experiments carried out in Brazil, Costa-Coelho et al [165] reported that common bean seed yield was higher (627-1067 kg ha −1 ) in conventional tillage (years 2005/16 and 2006/07) compared to no tillage (218-290 kg ha −1 ), or minimum tillage (219-540 kg ha −1 ). The same researchers observed that the severity of web blight (Thanatephorus cucumeris) was reduced by 30% under the no-tillage (NT) system.…”

Common bean (Phaseolus vulgaris L.) is the most important legume for human consumption worldwide and an important source of vegetable protein, minerals, antioxidants, and bioactive compounds. The N2-fixation capacity of this crop reduces its demand for synthetic N fertilizer application to increase yield and quality. Fertilization, yield, and quality of common bean may be optimised by several other agronomic practices such as irrigation, rhizobia application, sowing density, etc. Taking this into consideration, a systematic review integrated with a bibliometric analysis of several agronomic practices that increase common bean yield and quality was conducted, based on the literature published during 1971–2021. A total of 250 publications were found dealing with breeding (n = 61), sowing density and season (n = 14), irrigation (n = 36), fertilization (n = 27), intercropping (n = 12), soilless culture (n = 5), tillage (n = 7), rhizobia application (n = 36), biostimulant/biofertilizer application (n = 21), disease management (n = 15), pest management (n = 2) and weed management (n = 14). The leading research production sites were Asia and South America, whereas from the Australian continent, only four papers were identified as relevant. The keyword co-occurrence network analyses revealed that the main topics addressed in relation to common bean yield in the scientific literature related to that of “pod”, “grain”, “growth”, “cultivar” and “genotype”, followed by “soil”, “nitrogen”, “inoculation”, “rhizobia”, “environment”, and “irrigation”. Limited international collaboration among scientists was found, and most reported research was from Brazil. Moreover, there is a complete lack in interdisciplinary interactions. Breeding for increased yield and selection of genotypes adapted to semi-arid environmental conditions combined with the suitable sowing densities are important agronomic practices affecting productivity of common bean. Application of fertilizers and irrigation practices adjusted to the needs of the plants according to the developmental stage and selection of the appropriate tillage system are also of high importance to increase common bean yield and yield qualities. Reducing N-fertilization via improved N-fixation through rhizobia inoculation and/or biostimulants application appeared as a main consideration to optimise crop performance and sustainable management of this crop. Disease and weed management practices appear neglected areas of research attention, including integrated pest management.

“…Previous research has revealed that R. solani acts as a major seed-borne phytopathogenic fungus that causes diverse plant infections, with an annual crop damage range of 20-40% [60], sometimes reaching crop losses of 100% [58]. These results and others have shown that R. solani is highly virulent for P. vulgaris [61][62][63][64][65].…”

Biodiversity of Rhizoctonia solani in Phaseolus vulgaris Seeds in East Delta of Egypt

et al. 2023

Seventy-eight common bean (Phaseolus vulgaris L.) seed samples were collected from twenty-one field locations across six governorates (Ismailia, Sharkia, Port Said, South Sinai, North Sinai, and Suez) in the East Delta region of Egypt between 2021 and 2022. Thirty-five Rhizoctonia solani Kühn were isolated. Sharkia had the highest percentage of R. solani isolates (RS) from the collected samples (59%), followed by Ismailia, South Sinai, Suez, North Sinai, and Port Said (49.7%, 36.7%, 33%, 29.2%, and 27.8%, respectively). Pathogenicity tests proved that the seven highest-virulence strains of R. solani had a pre-emergence damping off ranging from 17% to 30% and a post-emergence damping off ranging from 11% to 20%. The seven most pathogenic isolates were identified using the Internal Transcribed Spacer (ITS) with code numbers as follows: R. solani RSA1, R. solani RIT2, R. solani RIF3, R. solani RSoR4, R. solani RNB5, R. solani RSzA6, and R. solani RPS11. Principle component analysis (PCA), which depends on the pathogenicity result and soil variables, revealed that soil texture and soil water holding capacity (MWHC) were the most effective factors in grouping and clustering the studied R. solani isolates from the different locations into two groups. From this study, it can be established that the biodiversity of R. solani in the East Delta area of Egypt depends on changes in the environmental conditions and soil variables. The soil type and pH variables have the greatest impact on R. solani diversity, followed by the humidity-holding ability and soil porosity.

“…Lignin content in grasses with high C/N ratio were reported to increase populations of microbes that degrade R. solani microsclerotia (Van Beneden et al., 2010). Cultural practices for WB management should avoid the use of residues and cover crops with low C/N ratios (Costa‐Coelho et al, 2016).

Common bean (Phaseolus vulgaris L.) production in the humid tropics may increase if less predictable rainfall becomes a serious seed yield constraint in traditional areas of production. The successful production of common bean will require the effective management of common bean diseases favored by hot and humid conditions. Web blight (WB), caused by Thanatephorus cucumeris (Frank) Donk, is a serious disease of common bean in the humid tropics causing significant losses in both seed yield and seed quality. At present, only moderate levels of WB resistance have been identified. Leaf and seed damage and leaf lesion size are criteria that have been successfully used to screen common bean genotypes for WB resistance in the greenhouse and in the field. Pedigree selection has been successfully used to develop cultivars having moderate levels of resistance. Recurrent selection has been used to broaden the genetic base and to produce progeny having higher levels of WB resistance. Sources of resistance from secondary gene pools should be used to combine resistance genes from diverse sources. Common bean cultivars with earlier maturity, deep tap roots, and terminal drought tolerance may be desirable traits for farmers who plant later in the wet season to avoid WB. Seed production during the dry season using irrigation would help to reduce infection of the seed and transmission of the WB pathogen. Minimum tillage techniques are useful to help to reduce the spread of the disease. Biological control may contribute to the management of WB and complement genetic resistance.
