The cultivated peanut (Arachis hypogaea L.) is one of the most widely consumed legumes globally due to its nutrient content, taste, and affordability. Nutrient composition and consumer preference were determined for twenty local farmer (landrace) and commercial peanut varieties grown in the Nakaseke and Nakasongola districts of the central wooded savanna of Uganda through sensory and laboratory evaluation. Significant differences in nutrient content (p < 0.05) among peanut varieties were found within and across sites. A significant relationship between nutrient content and consumer preference for varieties within and across sites was also realized (Wilk’s lambda = 0.05, p = 0.00). The differences in nutrient content influenced key organoleptic characteristics, including taste, crunchiness, appearance, and soup aroma, which contributed to why consumers may prefer certain varieties to others. Gender differences in variety selection were significantly related to consumer preference for the crunchiness of roasted peanut varieties (F = 5.7, p = 0.016). The results imply that selecting different varieties of peanuts enables consumers to receive different nutrient amounts, while experiencing variety uniqueness. The promotion of peanut intraspecific diversity is crucial for improved nutrition, organoleptic appreciation and the livelihood of those engaged in peanut value chains, especially for the actors who specialize in different peanut products. The conservation of peanut diversity will ensure that the present and future generations benefit from the nutritional content and organoleptic enjoyment that is linked to unique peanut varieties.

Knowing the nutrient removal by soybean grain harvest in different varieties, locations, and over time is essential to correctly adjust agronomic recommendations, update farmers’ practices, and increase nutrient use efficiency. A field-based research trial was carried out to assess macronutrients [nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), and sulfur (S)] removed in grain by modern soybean varieties from southern Brazil introduced between 2007 and 2016. We examined changes between our set of modern varieties and a dataset of historical values encompassing a wide range of varieties introduced before 2007. Moreover, we undertook a synthesis analysis using scientific literature published after 2007 to investigate nutrient removal by grain among modern Brazilian soybeans and a dataset that included field trials from Argentina, United States, and India. There were no yield gains across the years for modern soybean varieties introduced among 2007 and 2016 in Brazil, although the grain N and Mg concentrations decreased. Modern Brazilian soybeans increased nutrient removal compared with that by soybeans historically planted in Brazil, with 11.1, 26.9, 45.0, and 31.6% more N, P, K, and Mg removed, respectively. Our results indicated that soybean growing in Brazil removed 4.3% less N relative to the values reported in the literature dataset, whereas K removal was 21.4% greater. A significant difference was also recorded for high-yield soybean varieties, and Brazilian varieties removed 11.8% less N and 8.6% more K than varieties in the literature dataset. No differences were found among locations for P removal, averaging 4.9 kg Mg–1 grain. In conclusion, this study indicates that the amounts of nutrients removed by modern soybean varieties were greater relative to the historical values recorded in Brazil, excluding Ca and S. Nonetheless, in the middle to long term (10 years), a significant impact of plant breeding on grain nutrient concentration was recorded only for N and Mg. The difference in nutrient removal patterns between Brazil and other countries indicates an integrated effect of management, genotype, and environment on nutrient removal. These findings provide guidance for optimal nutrient management and specific information for plant breeding programs to understand nutrient variability.

The purpose was to assess the effect of sowing rate and variety on the nutrient content of field peas. The varieties were: Bruno, Capella, Clara, Kirke, Onward, Vitra. Treatments: sowing rate of 120 seeds per m2 for all varieties; sowing rate of 144 seeds per m2 for all varieties. Increased sowing rate made followed changes: increased the content of Nitrogen in varieties Bruno, Kirke and Onward; increased the content of Phosphorus in all varieties in 2015, while only in varieties Clara and Onward in 2016; decreased the content of Potassium in varieties Bruno, Kirke and Vitra in 2016; decreased the content of Calcium in variety Bruno; decreased the content of Magnesium in variety Kirke in 2015 and in varieties Onward and Vitra in 2016. The highest contents of Nitrogen, Potassium and Calcium were in variety Onward. In 2015, the highest content of Phosphorus was in variety Onward, while in 2016 the highest content was in variety Bruno. The highest content of Magnesium was in varieties Bruno, Onward and Vitra. Increased sowing rate did not have a constant influence on the nutrient content of field peas. We can recommend to grow variety Onward, as the variety with high nutrient content.

Aboveground biomass and nutrient accumulation differ among varieties of sugarcane (Saccharum spp. hybrids) throughout the crop development. This study aimed to identify irrigated sugarcane varieties with similar pattern of aboveground biomass production and nutrient extraction using cluster analysis and to determine the nutritional requirement during the plant cane cycle. Aboveground biomass production and nutrient content (N, P, K, Ca, and Mg) of sugarcane varieties (SP79-1011, RB813804, RB863129, RB872552, RB94336, RB72454, RB763710, SP78-4764, SP81-3250, RB867515, and RB92579) were determined at 120, 180, 240, 300, and 360 days after planting (DAP). Sugarcane varieties were clustered using the Ward’s method based on aboveground biomass and nutrient accumulation. Next, the increase in aboveground biomass per month and nutritional requirement were determined for the varieties clusters. The sugarcane varieties were clustered in five groups: G1: RB92579; G2: RB863129 and SP81-3250; G3: SP78-4764 and RB867515; G4: SP79-1011; and G5: RB872552, RB813804; RB763710, RB72454, and RB943365. The RB92579 (G1) produced the highest aboveground biomass accumulation, corresponding to an average of 23 Mg ha⁻¹ higher than the other varieties. The SP79-1011 (G4) exhibited constant aboveground biomass production in the last phase. The highest nutritional demand was observed for most of the varieties at the beginning of the stalk elongation phase (120 DAP), except for SP78-4764 and RB867515 (G3), which showed at beginning of the tillering phase (30 DAP). The nutritional requirements decreased during the final stage of stalks elongation phase. These findings suggest that nutritional management of sugarcane must consider the variety and growth phase.

This study reports the effect of conjoint application of inorganic fertilizers with organic manure on some leaf and fruit characteristics of four high yielding walnut varieties of Kashmir. The experiment consisted of four different nutrient supplementation: inorganic fertilizer, vermicompost, poultry manure and farmyard manure used in different combinations.All treatments were mixed well with soil and applied in the first week of December during 2016 and 2017. Leaf nutrient status of different varieties varied non-significantly however treatments had a significant effect on leaf nutrient status. SPAD index of SKAU/040 variety was significantly higher than rest of the varieties. SKAU/008showed significantly higher protein and phenolic content with higher antioxidant activity than rest of the varieties. Pooled data recorded varieties treated with T4 showed highest value of SPAD index and leaf macro and micronutrients. Conjoint application of inorganic manure with vermicompost showed maximum fruit yield and fruit weight in selection SKAU/008. Overall integrated management improved the protein, fat, ash content, higher total phenolic content and enhanced antioxidant activity. Thus, conjoint application of inorganic fertilizers with vermicompost should be preferred over other organic manures for maximizing fruit yield, nutritional and nutraceutical content of walnut fruits with substantial improvement in leaf nutrient status irrespective of the walnut variety used.

Quinoa has a long history of cultivation and unique nutritional value. Quinoa sprouts can be eaten as leafy vegetables, but their nutritional quality is unknown. Ten quinoa sprout varieties (lines) were evaluated and compared for nutrient and functional composition. All quinoa sprout varieties had high contents of moisture content, reducing sugar, potassium, magnesium, and vitamin C. All varieties contained all essential amino acids, with leucine present in abundance. They had high contents of phenolics, flavonoids, carotenoids (β-carotene and lycopene) as well as chlorophylls a and b. Overall, var. LL-01 had better nutrient and phytochemical composition than other varieties. The potential nutritionalhealth benefits of quinoa sprouts as a vegetable are important for both traditional and contemporary diets.

High-yielding varieties (HYVs) of rice have benefited farmers and the public by increasing yields and reducing the cost to consumers. Yet the nutritive value, a pivotal trait of HYVs remains grossly under-investigated. In this work, efforts have been specifically focused on nutrients profiling of 20 popular HYVs from Assam as brown rice and its milled counterparts. The study has revealed several varieties that are a reasonably good source of either protein, or fat, or zinc, or calcium. Substantial nutrient variability was observed in the 20 HYVs brown rice with the largest variation observed in pyridoxine (49%cv), followed by pantothenic acid (36%cv), iron (24%cv), protein (14%cv), and fat (13%cv). At 5 % milling substantial reduction of all nutrients occurred (40–58%) which was further exacerbated at 10 % milling. Compared to 10 % milled rice, brown rice has a far better nutrient profile and even limiting to 5 % milling can marginally increase rice nutrient content. A change in consumption pattern from white rice to brown rice or even 5% milled rice will be nutritionally beneficial. The rice nutrient data can also help in improving nutrient intakes through the use of nutritious cultivars and in conventional plant breeding to develop superior nutrient varieties.

The article presents the results of a study on the study of the peculiarities of rhizogenesis of local grape varieties adapted to the conditions of Azerbaijan. The rooting of grapes in in vitro culture is determined by the mineral and hormonal composition of the nutrient medium, the morphological development of regenerated plant varieties. The culture of grapes, on average, takes root well both in natural conditions and on artificial nutrient media. However, obtaining a high quality root system (branched, without callus tissue at the base of the root) requires the determination of a suitable nutrient medium and cultivation conditions. The objects of the study were microcuttings of local grape varieties of Madrasa and Bayan Shirey, as well as Murashige and Skoog (MS) medium, modified with various combinations and concentrations of auxins and cytokinins (IBA, BAP, 2ip) in 9 variants. The research results showed that the main factors affecting the intensity and quality of rooting are the concentration and type of auxin in the nutrient medium. So, the optimal medium for in vitro rooting of both grape varieties was MS medium with an IBA content of 1.0 mg/l, except for the number of roots, the maximum number of which was obtained on MS medium with a 2.0 mg/l IBA content.

Most faba bean research is about protein content while less attention is paid to nutrient content. Thus, the purpose of this study was to assess the effect of sowing rate and variety on the nutrient content of faba beans. Five varieties were tested: Bauska, Gloria, Julia, Jõgeva, and Lielplatones. Two sowing rates were used: 30 seeds m−2 (100%) and 36 seeds m−2 (120%). The higher sowing rate decreased the K content in varieties Gloria, Julia, and Lielplatones in 2016. In 2015 the higher sowing rate increased the Ca content while in 2016 the sowing rate decreased the Ca content. The higher sowing rate increased the Mg content in varieties Gloria and Jõgeva in 2016. The highest N, K, and Mg contents were found in variety Gloria. In 2015 the highest K content was found in varieties Gloria and Jõgeva, while in 2016 the highest K content was in variety Lielplatones. The highest Ca content was in variety Bauska. In conclusion, an increased sowing rate did not have a consistent effect on the nutrient content of faba beans. Thus, variety Gloria can be recommended for faba bean production in Northern Europe because it was the variety with the highest nutrient content.
