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.

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.

<p>ABSTRACT</p><p>Rainfed ricefield, planted at least for one cropping season in a year, depends heavily on rainfall for its water supply. This land generally is low in fertility as indicated by the limited availability of essential plant nutrients in particular nitrogen (N), phosphorus (P), and potassium (K) as well as organic matter. Its productivity is relatively low with a rather erratic precipitation distribution. In order to overcome fertility issue in rainfed land, it is necessary to conduct an integrated nutrient management; one of which is by implementing location specific nutrient management. This study aims to seek the appropriate nutrient management in rainfed paddy field of Semawung village in the sub-district of Andong of Boyolali regency to be provisioned as a technological tool of location specific nutrient management. Research on nutrient management of gogo rancah system-based paddy production was carried out from October 2014 to January 2015. The field experiment was arranged in a Randomized Block Design involving eight treatments and three replications for each treatment. Treatments were combinations of NPK fertilizer, Organofosfat, and straw-based organic fertilizer. Nutrient management using NPK fertilizer and its combination with Organofosfat or organic fertilizer had very significant effect on plant height and number of stem per hill, significantly affected number of panicle per hill, panicle length, and number of fully-filled grain but did not result in difference of fully filled grain percentage and weight of 1000 grains. There was no significant difference between the treatment of 100% of NPK fertilizer and the combination of 75% of NPK fertilizer with straw-based fertilizer regarding these variables: number of stem per hill, number of panicle per hill, panicle length, number of grain per hill, number and percentage of fully-filled grain, weight of 1000 grains, and weight of fresh grain and milled grain yield. Therefore, the latter treatment is feasible as an option of location-specific nutrient management Semawung village.</p>

The yield, protein and starch content of Martonvásár maize hybrids belonging to different FAO groups were examined in experiments involving early, optimal and late sowing dates in two different years (drought — 2007, favourable water supplies — 2008) on a calcareous chernozem soil with loam texture at the Látókép Experimental Station of the Centre of Agricultural Sciences and Engineering, University of Debrecen.Sowing date had a significant effect on maize grain yield in the dry year. The grain yields of hybrids with longer growing periods were significantly higher than those with shorter growing periods in both years, but they reacted sensitively to the change in sowing date in the dry year. Due to the rainfall distribution in the growing season, sowing date did not modify the performance of the hybrids in the year with favourable water supplies. Sowing date had a significant effect on the grain protein content in the dry year, with significantly higher values after late sowing than after early or optimal sowing. Averaged over the sowing dates, the protein content of the FAO 200 hybrid was significantly higher in both years than that of hybrids in other FAO groups. In the dry year, the greatest difference in protein content could be observed between the early and late sowing dates for hybrids in all four FAO groups. A negative correlation was found between yield and protein content. Sowing date significantly increased the starch content of maize in the favourable year, with a significant difference between early and late sowing dates.In the dry year higher starch contents were recorded for all the hybrids and for all the sowing dates than in the favourable year. In the dry year, sowing date only caused a significant difference in the starch content in the case of FAO 200 sown at optimal and late sowing dates. In the favourable year, a significant difference was only obtained for the starch content of the FAO 400 hybrid sown at early and late sowing dates. Satisfactory quality can only be achieved if suitable genotypes are grown with appropriate technologies.

Several maize hybrids that present the phosphinothricin acetyltransferase gene (pat) are available in the market. However, these hybrids have different resistance levels to glufosinate herbicides. The objective of the present work was to evaluate the resistance of maize hybrids containing the pat gene (as a selection marker) to glufosinate. Field experiments were conducted in two sites in the 2016/2017 crop season, using a randomized block design with a 2×7 factorial arrangement and four replications. The treatments consisted of two glufosinate rates (0 and 500 g ha-1) and seven maize hybrids, six containing the pat gene as a selection marker (Herculex®, Agrisure-TL®, Herculex Yieldgard®, Leptra®, Viptera-3®, and Power-Core®) and one without the pat gene (VT PRO®). Two field experiments were conducted in different sites. The analyzed variables were: ammonia accumulation, electron transport rate (ETR), percentage of injuries, 100-grain weight, and grain yield. The glufosinate-susceptible maize hybrid presented higher ammonia accumulations, lower ETR, and high percentage of injuries (100%), which caused total loss of grain production. Considering the evaluated glufosinate-resistant maize hybrids, Viptera-3 and Agrisure-TL presented the highest ammonia accumulations and percentages of injuries, and lower ETR than the other hybrids. The grain yield of glufosinate-resistant maize hybrids was not reduced due to the application of the 500 g ha-1 of glufosinate. Thus, glufosinate-resistant maize hybrids containing the pat gene are resistant to the application of 500 g ha-1 of glufosinate, and this practice can be recommended for maize crops.

The objective of this study was to evaluate the response of irrigation and foliar application of fungicide on the burned grain complex, fungal incidence (Blotter test) and grain yield of two maize hybrids. The experiments were conducted in the agricultural crop 2014/15, in Cruz Alta, RS. For both experiments, the treatments were arranged in a randomized block design and arranged in factorial scheme:2 (commercial hybrids) x 4 (3 fungicides and 1 control), with 4 replicates. In the laboratory, the grains were evaluated, as percentage of burned grains, grain sanity by Blotter test method, weight of one thousand grains and grain yield. There was influence of the use of irrigation, the hybrid, and the application of fungicides on grain yield and the incidence of burned grains and phytopathogenic fungi. Irrigation favored a higher incidence of burned grains and fungi Fusariumsp. and Aspergillussp. The hybrid BG7060HR provided a lower incidence of fungi and burned grains, parallel to a greater mass of a thousand grains and productivity when the fungicide Azoxystrobin + Benzovindiflupir was applied. The application of fungicides in the V8 stage of the culture reduced the incidence of fungi Fusariumsp.and Aspergillussp., especially the fungicide Azoxystrobin + Benzovindiflupir.

An improvement in the quality of maize grain by increasing the level of components responsible for its biological value is possibleby using genetic means. However, a change in the genotype, together with improving the nutrient properties of the grain, also has someadverse consequences connected with a fall in yield and in resistance to diseases.Field experiments were conducted during three years (2003, 2004and 2005) to evaluate environmental effects on grain yield andquality responses of maize hybrids. Twenty one hybrids of various maturity groups (FAO 150-400) were planted to achieve an optimum(60-70 000 plants per hectare) plant populations and grown under the medium-N (80 kg N ha-1) fertilization. Environmental conditionssignificantly affected maize hybrid responses for grain yield, starch, oil and protein contents, and consequently, starch, oil and proteinyields per hectare. Hybrids of flint type, which have a short vegetation period, had high protein and oil content but the yield averageswere low due to the slower rate of starch incorporation. Hybrids of the dent type have a longer growing season and more intensecarbohydrate accumulation, but low protein and oil contents. In wet years there was a higher rate of starch accumulation, while dryyears are favorable for protein and oil accumulation. Positive correlation existed between starch content and grain yield and 1000-weight as well as between oil content and volumetric weight among tested hybrids. Negatively correlation existed between grain oil andstarch content as well as between oil content and grain yield and 1000-weight. Thus, end-users that require high quality maize may needto provide incentives to growers to off set the negative correlation of grain yield with oil and protein content.

Yield And Yield Components

In order to determine the effects of sowing date on physiological characteristics, yield and yield components of six sweet maize hybrids, an experiment was arranged in split plot based complete randomized block design with three replications. Sowing date in two levels (15 June and 1 July) and sweet maize hybrids in six variants (‘Chase’, ‘Temptation’, ‘Challenger’, ‘Basin’, ‘Obsession’ and ‘Ksc403su’) were the treatments. Results of ANOVA revealed significant difference of sowing date and sweet maize hybrids on the number of days for tassel emergence, number of days to anthesis, plant height, cob height, stem diameter, plant dry weight, cob dry weight, number of grain rows, length flowers, number of leaf above the cob, raffinose content of grain and grain yield. Mean comparisons showed that the highest grain yield was obtained for ‘Basin’ variety and it was obtained from the crop established on the 15th of June as planting date. In temperate regions, maize potential productivity seems to be more limited by the amount of solar radiation available around silking (determinant of grain set) than during grain filling (determinant of grain weight).

The objective of this work was to evaluate the agronomic performance of corn hybrids, the interrelations of the characters with the grain yield, and to genetically discriminate the corn hybrids by means of the dispersion analysis of the canonical variables. The experiment was conducted in the agricultural crop of 2013/2014, in an area belonging to the Federal University of Santa Maria, Campus of Frederico Westphalen, RS. The experimental design was a randomized block design, with four replications. The treatments were composed of seven maize hybrids with different genetic bases and maturation cycles. The LG 6304 modified simple hybrid has higher grain yield than the others. The characters plant height, spike insertion height and number of grains per row of spike have positive interrelations with grain yield of corn hybrids. Hybrids are not grouped according to the genetic basis and maturation cycle. The canonical variables explain 94.62% of the existing genetic variation, and allows the formation of five groups of maize hybrids.
