Humic and fulvic acid influence the morphophysiological and biochemical properties of cowpea (Vigna unguiculata) under water deficit
Context Water deficit is a limiting factor in cowpea (Vigna unguiculata) performance. Humic and fulvic acids are organic fertilisers that increase plant productivity and appear as a viable alternative to improve cowpea productivity under water deficit.Aim We evaluated the efficiency of humic and fulvic acid on the morphophysiological and biochemical properties of cowpea subjected to water deficit.Methods The experiment was conducted in a greenhouse. A completely randomised design was adopted in a 5×2 factorial scheme with four replications, with five doses of humic and fulvic acid, 0, 4, 8, 12 and 16mL/L applied to plants irrigated at 100% and 25% of field capacity. Stomatal conductance (gs), water potential (Pw), plant height (H), stem diameter (SD), number of leaves (NL), number of root nodules (NR), fresh and dry weight of the aerial (FMA and DMA) and root (FMR and DMR), total soluble proteins (SP) and total phenolic compounds (PC).Key results Doses of 8 and 12mL/L increased gs (100–200mmolm2s−1), reduced Pw (−0.9MPa) and NR, increased FMR and DMR (20 and 10g), SP (8–9g) in stressed and non-stressed individuals.Conclusions Intermediate doses of humic and fulvic acid (12mL/L) are recommended for cowpea production in dry regions.Implications Humic and fulvic acid together are viable alternatives for optimising agricultural production and decision making in semi-arid regions.
期刊介绍:
Crop and Pasture Science (formerly known as Australian Journal of Agricultural Research) is an international journal publishing outcomes of strategic research in crop and pasture sciences and the sustainability of farming systems. The primary focus is broad-scale cereals, grain legumes, oilseeds and pastures. Articles are encouraged that advance understanding in plant-based agricultural systems through the use of well-defined and original aims designed to test a hypothesis, innovative and rigorous experimental design, and strong interpretation. The journal embraces experimental approaches from molecular level to whole systems, and the research must present novel findings and progress the science of agriculture.
Crop and Pasture Science is read by agricultural scientists and plant biologists, industry, administrators, policy-makers, and others with an interest in the challenges and opportunities facing world agricultural production.
Crop and Pasture Science is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
