Some leguminous crops are known for N fixing ability; however their establishment with P fertilization enhances
nodulation and hence fixation of atmospheric N (Masinde and Omolo, 2007).
Transthoracic ultrasonography was performed and revealed right massive complex nonseptated pleural effusion, no pleural thickening or
nodulation, and a hyperechogenic collapsed lung that favored the presence of calcification (Fig.
The use of Carrageenan PGP for mungbean also gave the following results: more branches, more flowers which became pods, longer pods with more seeds, larger and heavier seeds, extended flowering and pod formation, increased priming from three to six; and extensive root system and
nodulation.
Soil chemical and physical properties, plant total biomass, tea yields, foliar elemental contents, extent of root nitrogen (N)
nodulation and mycorrhizal colonisation were assessed.
Growth,
nodulation and yield response of Cowpea to phosphorus fertilizer application in Ghana.
These effects can be due to various mechanisms, including early BNF of the nodules, increment in nodule dry matter, promotion of the occurrence of heterologous
nodulation through the increase in the formation of root hairs and secondary roots, with increment in the sites of infection, inhibition of pathogens and production of phytohormones and influences on dry matter partition among roots and shoots (Barbaro et al., 2009).
Given the variation in physicochemical properties of the soils of lower eastern Kenya [8], selection of efficient strains of rhizobia for cowpea
nodulation in different soils is an important step towards yield improvement.
This may be associated with the effects of deep tillage, which tends to provide better aeration in the plant root region and improves drainage in the soil profile affecting
nodulation, which is very sensitive to water excess (SARTORI et al., 2015).
