“…Termination of starch synthesis at different growth stages is known to cause higher variability in particle structure and properties of the starch granules (Wang et al, 2016). The effect of nitrogen rates on granule size distribution was also demonstrated in rice cultivated with varying levels of nitrogen (Zhu et al, 2017). In this study, our findings also revealed that N rate significantly influenced the volume distribution of rice starch granules.…”

“…The effects of nitrogen fertilization rates on the thermal properties of starch were also reported by Zhu et al (2017), who observed that high nitrogen levels resulted in considerably higher enthalpy (∆H gel ) and lower gelatinization temperature. The different gelatinization temperatures at the different N fertilization rates may be related to the observed differences in granule sizes, as well as crystallinity.…”

This study evaluated the effect of nitrogen fertilization rates on the characteristics of potato starch. The experimental design was randomized block with four replications. The treatments were composed of four rates of N (0, 80, 120 and 160 kg ha -1 ). After 117 days of planting the harvested tubers were sanitized and the starch extracted. The starches of the different treatments were analyzed for the shape and distribution of size, X-ray pattern, crystallinity, amylose, minerals, pasting and thermal properties. Results showed that the fertilization did not cause alteration in the shape of the starch granules but the sizes of granules increased with the application of higher rates of nitrogen fertilizer. All potato starches had X-ray pattern B-type and crystallinity decreased when nitrogen fertilizer rates increased up to 120 kg ha -1. Fertilization did not interfere in content of amylose. Nitrogen rates promoted a decrease in the phosphorus, calcium and magnesium contents in the starches. The starches had their initial and peak temperatures of gelatinization decreased with increasing fertilizer rates, but there was no interference of this practice in the enthalpy. The highest peaks of viscosity and breakdown were observed in starch extracted from potatoes grown with the application of 80 kg ha -1 of Entec® 26 fertilizer. These results indicated important modifications in potato starch properties grown at different rates of nitrogen fertilization and can provide information for starch applications in the food and non-food industries.

“…Amylopectin mainly forms a crystalline zone, and amylose mainly forms an amorphous zone. The external environment cannot change the crystal type of starch, but it can change the crystallinity of starch . Results showed that the grain types of the Wx genotype were the same.…”

“…Nitrogen is an important and non‐negligible environmental factor affecting rice quality. Although the effects of nitrogen fertilizer on the properties of rice starch were verified in numerous studies, combining the trends and observations is difficult . Many studies suggested that nitrogen fertilizer is not contributing to rice quality improvement, but many research results showed that appropriate nitrogen can maintain and improve rice quality.…”

“…Although the effects of nitrogen fertilizer on the properties of rice starch were verified in numerous studies, combining the trends and observations is difficult. [19][20][21] Many studies suggested that nitrogen fertilizer is not contributing to rice quality improvement, but many research results showed that appropriate nitrogen can maintain and improve rice quality. Gu et al 22 suggested that the PKV, hot paste viscosity (HPV), cool paste viscosity (CPV) and BDV of starch decrease with increasing nitrogen fertilizer level; additionally, the eating quality is aggravated.…”

Effect of agronomic management on rice grain quality Part I: A review of Australian practices

et al. 2020

View full text Add to dashboard Cite

Crop yield dominates rice (Oryza sativa L.) industry research; however, it is grain quality that dictates the value and market acceptance of rice. Key parameters of rice grain quality include physical appearance, amenability to processing and the cooking and sensory properties. In Australia, rice farmers who do not meet defined high‐quality standards receive discounts to their payments. Consequently, even with high yields, poor grain quality can negatively impact grower returns. Despite the financial consequences, the quality of Australian grown rice is highly variable, because unfortunately, the underlying causes are poorly understood. The identification of genetic markers for specific traits largely dominates rice grain quality research, while research regarding the effect of crop management practices on grain quality is relatively sparse and generally lacks an Australian focus. Prior research that has assessed the effect of crop management practices on grain quality tends to focus primarily on milling quality and neglect the physicochemical and cooking properties. This review outlines the current state of knowledge of the role nutritional management, irrigation protocols, planting density, and the interaction with genotype and environment on rice grain quality. The review highlights the uniqueness of Australian management practices and that there is a need for future research to understand the impact of agronomic practices on rice grain quality in Australia. Understanding how each cultivar interacts with agronomic practices can help reduce the variability found within rice crops.
