The aim of this investigation was to estimate the effects of different amounts of nitrogen on the grain yield and nutritive value in two soybean genotypes (Laura and Lana). Studied varieties belong to different maturity groups (Laura is in the group I, while Lana is in the group II) and they both have reduced content of Kunitz trypsin inhibitor (KTI). Four treatments of fertilization were tested: 0 kg N ha-1, 30 kg N ha-1, 60 kg N ha-1 and 90 kg N ha-1. Field trials were carried out in dry land farming, at location Putinci, during the years 2008 and 2009. In both research years, variety Lana had higher grain yield and oil content then variety Laura. Method of nitrogen fertilization has been proved as an effective tool for increasing of grain yield and protein content in both varieties. The results of the study showed that application of 90 kg N ha-1 increased the grain yield and protein content of soybean more than application of other treatments (0, 30 and 60 kg N ha- 1). All nitrogen fertilization levels decreased the oil content.

Nitrogen fertilization is one of the main management systems that affects safflower (Carthamus tinctorius) production. However, the response of safflower to nitrogen fertilization may vary depending on the genotype and growing conditions. The objective of this study was to evaluate the influence of nitrogen fertilization on yield components, oil content, and protein content of safflower genotypes in subtropical conditions. Two experiments were performed to evaluate the effect of nitrogen fertilization (0 and 160 kg ha–1) on six safflower genotypes. The experiment was designed in randomized blocks, in a 2 × 6 factorial design, with six repetitions. The height of the plants, yield, and oil and protein contents were determined 170 and 160 days after emergence in 2017 and 2018, respectively. The oil content and protein content of safflower genotypes were affected by nitrogen fertilization, but this effect varied depending on the genotype. Genotype 4 dominated with a grain yield of 1088 kg ha–1 and an oil yield of 215 kg ha–1. Nitrogen fertilization increased the grain yield, oil content, and protein content; thus, it is appropriate for the cultivation of safflower off-season in autumn-winter in subtropical conditions. Safflower genotype 4 could be a promising oilseed crop for southern Brazil when fertilized with 100 kg ha–1 of N.

AbstractIn recent years, producers of agricultural products have increased the use of chemical fertilizers per unit area. The goal of this research was to analyze the interaction of genotype in treatment (NPK fertilizer) on grain yield, protein content, oil content, and the starch content on 13 maize hybrids using analysis by the model of additive and multiplier effects AMMI and to evaluate genotypes, treatments, and their interactions using biplot in Hungary. Treatments include NPK0 (N: 0 kg/ha, P2O5:0 kg/ha, K2O: 0 kg/ha), NPK1 (N: 30 kg/ha, P2O5: 23 kg/ha, K2O: 27 kg/ha), NPK2 (N: 60 kg/ha, P2O5: 46 kg/ha, K2O: 54 kg/ha), NPK3 (N: 90 kg/ha, P2O5: 69 kg/ha, K2O: 81 kg/ha), NPK4 (N: 120 kg/ha, P2O5: 92 kg/ha, K2O: 108 kg/ha), NPK5 (N: 150 kg/ha, P2O5: 115 kg/ha, K2O: 135 kg/ha) in four replications based on complete randomized block design in 2019. The NPK fertilizer effects indicate that the fertilizers are different on yield genotype. AMMI analysis showed that there was a significant difference between genotypes, treatment, and the interaction effect of genotype * treatment at one percent. Besides, the maximum yield had Loupiac and NPK3 on grain yield, Loupiac and NPK2 on oil content, P0023, and NPK3 for starch content, DKC 3/ES4725 (DKC4725) and NPK3 for protein content. Also, GGE biplot analysis indicates that had maximum grain yield in Loupiac, protein content in P9978, oil content in MV Maronetta, and starch content in Sushi.

The Relationship

During 1995/96 and 1996/97, experiments were carried out at Londrina State University, aiming at quantifying the oil and protein contents in two groups of soybean genotypes; estimating the phenotypic, genotypic and environmental correlations existent among oil, protein content and seed size, and identifying genotypes for direct human consumption with high protein content. The evaluated characters were Weight of a Hundred Seeds (WHS), expressed in grams/100 seeds, Oil Content (OC) and Protein Content (PC), expressed in %. In the experiment carried out in the field, OC ranged from 12 to 20.37 % and PC from 35.66 to 41.75% while in the experiment carried out in the greenhouse OC ranged from 12.26 to 21.79 % and PC from 32.95 to 41.56 % . The correlations between oil and protein were negative and significant. The relationship among WHS with OC and PC was low and higly affected by the time effect. Due to their high protein content and stability to oil and protein contents, there were distinction among the treatments carried out in the field (GA23 and GA20), and those carried out in the greenhouse (PI408251, Waseda, B6F4 (L-3 less), PI423909 and Tambagura).

The aim of this investigation was to estimate the effects of foliar fertilization on quantitative traits (plant height, first pod height, number of nodes per plant, number of pods per plant, number of grain per plant, grain yield per plant, 1000-grain weight and grain yield) in two soybean cultivars (Balkan and Becejka). Studied cultivars belong to different maturity groups (Balkan - I and Becejka - 0). Four treatments of fertilization were tested: control (no fertilization), Urea (46 kg N ha-1), Urea (46 kg N ha-1) + Wuxal super (5 l ha-1) and Urea (46 kg N ha-1) + Ferticare I (5 kg ha-1). Wuxal super and Ferticare I were foliar applied two times at the R2-R3 growth stage. The field experiments were carried out in dry land farming in the region of Vojvodina province at location Putinci (45? 00? N Lat., 19? 58? E Long.), during the years 2007 and 2008. In both research years, Balkan had higher values for all investigated traits than Becejka. Results showed that foliar fertilizers significantly increased the values for all quantitative traits. Ferticare I is more effective than Wuxal super in soybean because this fertilizer has higher concentration of macronutrients. Foliar fertilization of soybean reduced the negative impact of small amounts of rainfall during the summer months on grain yield.

Among the traits that may add commercial value to maize (Zea mays L.), those related to nutritional quality, specially protein and oil content, are of great interest to the feed industry. The objective of this work was studying the variability of protein and oil content, as well as yield, in a group of maize testcrosses. One hundred and twenty S1 families of the ESA23B maize population were crossed with two testers, an open-pollinated population (BR108) and an exotic line (CML269). Testcrosses were evaluated at two locations under a completely randomized block design with three replications. Ear and grain yield, protein and oil content were evaluated. The three-way interaction location x tester x progeny was significant for all traits, except for oil content. Differences among progenies were detected for all traits. Testcross means varied from 8.40% to 11.82% for protein content and from 3.77% to 5.10% for oil content. Hybrids with similar or superior means to the best check were identified for protein content, ear yield, and grain yield. Estimates of the interpopulation additive variance ranged from 0.553 to 1.124 for protein content; 0.034 to 0.057 for oil content (percent data); 132.13 to 521.74 for ear yield and 116.33 to 381.73 for grain yield (data in grams per plant). The population ESA23B can potentially be improved for all the traits studied. Associations among traits were weak, thus concomitant selection of quality and yield can be feasible.

Soybean Genotypes

In order to ensure an ongoing and long-term breeding progress of soybean, stable sources of major quality traits across multi-environments need to be identified. Here, a panel of 135 soybean genotypes was tested in three different Chinese environments, including Beijing, Anhui, and Hainan during the 2017 and 2018 growing seasons to identify stable genotypes for cultivation under varying environmental conditions. The weighted average of absolute scores biplot (WAASB) for the best linear unbiased predictions of the genotype-environment interaction and multi-trait stability index (MTSI) were utilized to determine the stability of the soybeans for seven seed composition traits viz; protein content, oil content, and five fatty acids (palmitic, stearic, oleic, linoleic, and linolenic acids). Based on the WAASB index, the following genotypes were identified as stable genotypes for some specific traits; ZDD12828 and ZDD12832 for protein content, WDD01583 and WDD03025 for oil content, ZDD23040 for palmitic acid, WDD00033 for stearic acid, ZDD23822 for oleic acid, ZDD11183 for linoleic acid, and ZDD08489 for linolenic acid. Furthermore, based on MTSI at a selection intensity of 10%, 14 soybean genotypes were selected for their average performance and stability. Overall, the MTSI was shown to be a powerful and simple tool for identifying superior genotypes in terms of both performance and stability, hence, identifying stable soybean genotypes for future breeding programs of quality traits.

The Difference

The Barley Committee of the Laboratory of Brewing in Helsinki, carried out a series of field trials from 1967 to 1969 to investigate the effect of the timing and the quantity of nitrogen fertilization on properties of malting barleys grown in Finland. This paper deals with a part of this project. The varieties were the two-rowed brewing barleys Ingrid, Arvo and Karri and the six-rowed enzyme barley Pirkka. As a basic fertilizing 59 kg phosphorus and 99 kg potassium per hectare were administered. Varying nitrogen levels (30 or 60 kg N per hectare) were given as saltpetre at harrowing (early) or on the sprouts (late). The nitrogen given early increased the yield in all varieties more than the late spreading. The treatment on sprouts increased the protein content of the yield. The difference in protein contents between the two spreading times was as big as the difference between the two nitrogen doses given at the same point of time. Ingrid and Pirkka reacted very sensitively to the late nitrogen fertilizing. Karri was least sensitive to the changes in nitrogen supply. The yearly fluctuations of the protein contents were bigger than the differences between varieties in each year. The order of varieties in regard to the protein content was the same in all trial years: Pirkka, Ingrid, Arvo and Karri. Besides the cultivation technique, e.g. placement of fertilizers, attention must be paid to the sensitivity of the varieties in increasing their protein content under changeable conditions.
