“…These authors observed that in soybean/wheat, the amount of nitrogen fertilizer led to changes in the spike length and number of fertile and sterile spikelets. That way, the relationship between inflorescence oat (A. sativa) components with the management of nitrogen fertilizer can lead to the construction of efficient simulation models in expectation of grain yield (Cover et al, 2011).…”

Nitrogen fertilizer management modifies oat (Avena sativa) panicle components and its grain yield. The work aims to study the potential of the variables of oat (A. sativa) panicle with N-fertilizer, and to simulatate its grain yield using multiple linear regression in succession systems of high and reduced Nresidual release. The study was done in 2013 and 2014. The experiment was done in a complete randomized block of 4×2 factorial design, with four replications. The treatments include: nitrogen fertilizer of four doses (0, 30, 60 and 120 kg ha-1), oat (A. sativa) cultivars at two levels (Barbarasul and Brisasul) and succession system at two levels (soybean/oat (A. sativa) and corn/oat (A. sativa). The multiple linear models were efficient in the harvest index of panicle of soybean/oat (A. sativa) system, regardless of the dose evaluated. However, at high doses, the number of grain per panicle was included. In the corn/oat (Avena sativa) system, the harvest index of panicle, the number of grains and spikelets panicle were adjusted based on the model. The multiple linear regression efficiently simulates N-fertilizer to affect the grain yield of oat (Avena sativa) and one or more potential variables of panicle in the succession systems.

“…The oat grain yield is a result set of various components, such as total biomass, panicle weight, number grain per panicle, among others. Therefore, individual modifications and/or in combination that can increase or reduce the final yield [23].…”

“…Nitrogen rates in the corn/wheat system exert significant effects on grain yield, and the inflorescence components changed by thousand grain weight and grain weight per spike [9]. According to [23] is extremely important the relations that occur on weight of the oat panicle, because it includes both the number of grains as the weight grains, which are decisive on the final yield of the species.…”

The oat panicle components were changed by the forms of nitrogen use influencing productivity. The aim of the study was to determine the direct and indirect effects of oat panicle components on grain yield by N-fertilizer rates in succession systems of high and reduced release of N-residual. The study was conducted in the years 2013 and 2014 in a randomized complete block with four replications in a factorial 3 × 2, for nitrogen rates (30, 60 and 120 kg•ha −1) and oat cultivars (Barbarasul and Brisasul) the soybean/oat and corn/oat systems. The panicle weight and grain per panicle show greater sensitivity to the change of nitrogen rates. Grain yield was favored by the direct effect of harvest index panicle and indirect by grain weight per panicle. In the system soybean/oat, the grain weight of panicle shows greater efficiency in promoting positive direct effects on grain yield.

“…Black oat (Avena strigosa Schreb L.) belongs to the family Poaceae and has an annual cycle. This crop is important in the production system (Dias-Filho, 2014), and is a widely cultivated forage plant that produces high levels of dry matter, with a nutritional quality suitable for animals (Cover, Federizzi, & Pacheco, 2011). The main characteristics of black oats are rusticity, adaptability to poorly fertile soils, and vigorous growth, which allow their use as cover plants, as well as for high quality forage that is abundant in the winter period, when pastures in southern Brazil are compromised by low temperatures (Fontaneli et al, 2012).…”

Genetic improvement of black oats: a scientometric review

et al. 2023

There are few new black oat cultivars in Brazil; therefore a reduced number of cultivars are available for the most varied production regions. Strategies aimed at studying genetic variability, such as mutation induction, of the few cultivars available on the market represent alternatives to increase the variety in this sector. The objective of the present study was to prepare a scientometric analysis of studies of the genetic improvement of black oats (Avena strigosa L). The literature review was performed using data from the Web of Science (WoS) from 1945 to 2020. Initially, 859 articles were analyzed, which after refinement, were reduced to 404 for further analysis. This study provides a new method for quantitatively visualizing information regarding the development of this area over time. After searching and refining with the aid of the CiteSpace software (5.6 R4), graphic representations were developed of the scientific journals, authors, countries, subject categories, organizations, and individual publications extracted from the WoS. The results of the analysis indicated a growing trend in the number of publications on the genetic improvement of black oats, as well as the number of citations over the years studied.
