“…This indicates that amendments have a positive effect as their applications result in increased chlorophyll content in plants under salinity stress. This is in agreement with Ramzani et al [10], who confirmed that chlorophyll content in quinoa plants grown under saline conditions was positively affected by B and compost applications compared to the control treatment. Nevertheless, AZ-51 genotype showed no significant response in terms of SPAD values (Table 2).…”

“…The highest significant protein content was obtained in quinoa seeds grown in HS and B treatments in AZ-51 and AZ-103 genotypes, respectively (Table 3). These findings agree with results of previous experiments in which organic amendment applications into a saline soil improved the nutritional quality in quinoa seeds [10]. A similar response was observed in wheat grains grown in calcareous soils [54].…”

The objective of this study was to evaluate the individual and synergic effects of the application of Biochar (B), Humic Substances (HS), and Gypsum (G) on the soil properties of a saline–sodic soil, and plant growth and seed quality (polyphenols, protein and yield) of quinoa. Treatments included (B) 22 t ha−1, (HS) 5 kg ha−1, and (G) 47.7 t ha−1. Two quinoa genotypes from Arid Zones (AZ-51 and AZ-103) were selected and established in eight treatments. The B + HS + G combined treatment resulted in increases in root biomass of 206% and 176% in AZ-51 and AZ-103, respectively. Furthermore, electrical conductivity (ECe), sodium adsorption ratio (SAR), and exchangeable sodium percentage (ESP) decreased significantly in all treated soils. When compared to the control, ESP decreased 11-fold in the G treatment, and 9–13-fold in the B + G; B + HS; and B + HS + G treatments. Similarly, soil microbial biomass increased 112% and 322% in the B + HS + G treatment in AZ-51 and AZ-103 genotypes, respectively. Therefore, it can be concluded that the application of combined amendments (B + HS + G) represents an alternative for reclaiming degraded soils, including saline–sodic soils.

“…The application of biochar has shown a potential to improve the soil physical and chemical properties and plant growth under biotic (diseases, infection, and competition) and abiotic (heat, cold, drought, salinity, organic and inorganic pollutants, and nutrient deficiency) environmental stresses. In three stressed alkaline soils (drought, salt‐affected, and Ni‐contaminated) having a clay‐loam texture, Ramzani et al () applied acidified maize cob‐biochar with different sulfur rates and found that acidified biochar improved the physiological growth of Quinoa and decreased the pH of rhizosphere soil by 0.4–1.6 units and also reduced polyphenols and phytate (anti‐nutrients) significantly in all stressed soils. Moreover, acidified biochar reduced the Ni contents by 48% in Quinoa seed and decreased plant available Ni (DTPA‐Ni) by 38% compared to control under the Ni‐contaminated soil.…”

Impact of biochar properties on soil conditions and agricultural sustainability: A review

et al. 2017

This review summarizes the influences of pyrolysis conditions and feedstock types on biochar properties and how biochar properties in turn affect soil properties. Mechanistic evidence of biochar's potential for enhancing crop productivity, carbon sequestration, and nutrient use efficiency are also discussed. The review identifies the knowledge gaps, limitations, and future research directions for large‐scale use of biochar. Both pyrolytic parameters and feedstock types are considered to be the main factors controlling biochar properties such as nutrient content, recalcitrance, and pH. Biochar produced at low temperatures may improve nutrient availability and crop yield in acidic and alkaline soils, whereas high‐temperature biochar may enhance long‐term soil carbon sequestration. Biochar can also improve the efficiency of inorganic and organic fertilizers by enhancing microbial functions and reducing nutrient loss, thereby making nutrients more available to plants. Integration of biochar and chemical or organic fertilizers generally provides for better nutrient management and crop yield in most types of soils. Although biochar can improve degraded soils, it is not a panacea; as such, soil‐ and crop‐specific biochar are needed in order to ensure optimum crop yield and agricultural sustainability.

“…Nevertheless, the opposite occurs when organic-mineral fertilizer is used. This kind of amendment facilitates the absorption of important elements for energetic, metabolic and enzymatic activities of the plant due to the microorganism content (Ramzani et al, 2017).…”

Physiological performance of quinoa (Chenopodium quinoa Willd.) under agricultural climatic conditions in Boyaca, Colombia

2019

View full text Add to dashboard Cite

Quinoa (Chenopodium quinoa Willd.) is native to South America; it is characterized by its high nutrient contents and high adaptation capacity to diverse edapho-climatic conditions, which highlights it´s genetic variability expressed as multiple physiological and phenological responses. The objective of this research was to evaluate the physiological response and proximal composition of the grain to three types of fertilization under the environmental conditions of the municipality of Oicata (Boyaca, Colombia) located at 2,875 m a.s.l. The white Soracá variety was planted using a completely randomized design with four treatments and four replicates. It was observed that the fertilization sources have an effect on the physiological and phenological behavior, mainly on the number of leaves, length of stem and chlorophyll content. The reproductive stage and the proximal composition of seeds changed, which is attributed to the application of mineral organic fertilizer that improves the production of quinoa grains, while N-P-K contribution shows greater growth and vegetable development, but less yield.
