“…Similarly, Galani et al [47] reported that N fertilizer increased soluble carbohydrates, mainly sucrose, in sweet sorghum. Matching results were also presented by Almodares et al [48] and Asthir et al [6] in sweet sorghum and wheat, respectively. Taken together, all these findings suggest that high N dose stimulates soluble sugars biosynthesis and reduces their conversion into starch.…”

The availability and management of N are major determinants of crop productivity, but N excessive use has an associated agro-ecosystems environmental impact. The aim of this work was to investigate the influence of N fertilization on yield and grain quality of 6 durum wheat genotypes, selected from 20 genotypes as high- and low-yielding genotypes. Two N levels were applied from anthesis to maturity: high (½ Hoagland nutrient solution) and low (modified ½ Hoagland with one-third of N). Together with the agronomic characterization, grain quality analyses were assessed to characterize carbohydrates concentration, mineral composition, glutenin and gliadin concentrations, polyphenol profile, and anti-radical activity. Nitrogen supply improved wheat grain yield with no effect on thousand-grain weight. Grain soluble sugars and gluten fractions were increased, but starch concentration was reduced, under high N. Mineral composition and polyphenol concentrations were also improved by N application. High-yielding genotypes had higher grain carbohydrates concentrations, while higher concentrations in grain minerals, gluten fractions, and polyphenols were recorded in the low-yielding ones. Decreasing the amount of N to one-third ensured a better N use efficiency but reduced durum wheat agronomic and quality traits.

“…Wheat grain yield and quality is determined by genotype, environment and the interaction between them [6]. Among the environmental factors that affect strongly crop productivity and nutritional quality of cereal crops, fertilizers management is an important factor to obtain high yield and high quality harvests [7].…”

“…The starch content of SYN5 under HN was higher than that under LN, whereas YN7 exhibited a different trend ( Figure ). Moderate N rates enhanced starch accumulation in rice, wheat, and normal maize . The high starch content under MN might be attributed to the increased number of cells and starch granules in the endosperm because of the enhanced activities of soluble and bound invertases and sucrose synthase .…”

“…Appropriate N fertilization under fixed environmental conditions is essential for improving the yield and starch quality of selected hybrids while reducing N costs . Although N fertilization can increase the protein content of cereal crops, N application can initially increase and then decrease starch content . Appropriate N fertilization can enhance the activities of amylolytic enzymes and starch synthetic enzymes and promote cellular metabolism to optimize starch deposition, increase amyloplast production, and facilitate small starch granule synthesis.…”

Appropriate nitrogen fertilization is essential for improving grain yield and starch quality, while reducing N fertilizer costs. The starch physicochemical properties of two waxy maize hybrids, namely, Suyunuo5 (SYN5) and Yunuo7 (YN7), under N rates of 0 (zero N application [N0]), 150 (low N rate [LN]), 225 (moderate N rate [MN]), and 300 (high N rate [HN]) kg ha -1 are elucidated. Grain starch content initially increases, peaks at MN, and decreases as N rate is increased. N fertilization reduces the starch granule size of YN7. The starch granule size of SYN5 increases under MN. SYN5 exhibits high short/long amylopectin chain ratios under LN and MN. The short/long amylopectin chain ratio of YN7 is unaffected by MN but is increases by LN and HN. The swelling power of YN7 is similar among different N levels, whereas that of SYN5 increases under N fertilization. N fertilization changes starch pasting and thermal properties. Starch with large granules exhibit high trough, final, and setback viscosities and gelatinization temperatures. Starch with high long-chain ratios is susceptible to retrogradation. In conclusion, appropriate N application (225 kg ha -1 for SYN5 and 150 kg ha -1 for YN7) favors starch accumulation, and starch has high viscosity and low retrogradation tendency.

“…Citrus crops are relatively high nutrientsdemanding [4] and highly responsive to applied nutrients in the form of fertilizers particularly the nitrogen which is critical input involved in plant metabolism growth and in different biochemical processes [5]. Enhanced yield with improved fruit quality can be obtained with the application of proper and adequate fertilizers.…”

Aims: To determine the suitable combination of fertilizers for obtaining high quality fruits from Kinnow orchard. Study Design: The experiment was conducted in randomized block design with three replications per treatment on Kinnow mandarin. Place and Duration of Study: The experiment was conducted on seven years old earmarked plants at Experimental Orchard and in Post-harvest Technology Laboratory of the Department of Horticulture, CCS Haryana Agricultural University, Hisar, Haryana, India during the year 2016-17. Methodology: The treatments comprising of 11 combinations of Urea, K2SO4, ZnSO4, FeSO4 and boric acid which were laid out in randomized block design with three replications. Seven years old uniformly grown trees spaced at 6x6 m were selected for the present study and analyzed for yield and quality parameters such astotal soluble solids (%), acidity (%), ascorbic acid (mg/100 ml juice), juice content (%), TSS to acid ratio etc. Results: In comparison to other fertilizers combinations, the maximum fruit yield per plant (97.83 kg/plant), juice content (49.47%), total soluble solids (9.80%), TSS to acid ratio (11.95) and ascorbic acid content (32.30mg/100ml) and minimum acidity (0.83%), rag (24.00%) and peel content (25.60%) and peel thickness (3.42 mm) were registered with foliar application of Urea 1.0% + K2SO4 1.0% + ZnSO4 0.5% + FeSO4 0.5% + H3BO3 0.2%, however, the foliar spray of Urea, K2SO4, ZnSO4, FeSO4 and boric acid had no effect on number of seeds per fruit in Kinnow mandarin. Thus it is clear from results that foliar nutrient application showed a stimulating influence on yield and quality parameters of Kinnow fruits. Conclusion: From the research findings it can be concluded that the maximum potential of Kinnow mandarin plants in respect of fruit yield per plant, juice content, total soluble solids, TSS to acid ratio and ascorbic acid content was exploited to a maximum level and the acidity, rag and peel content and peel thickness to a minimum level with foliar application of Urea 1.0% + K2SO4 1.0% + ZnSO4 0.5% + FeSO4 0.5% + H3BO3 0.2%.
