“…Specifically, results from the NFSC trials [13,20,33,50,58,65] demonstrated that seasonal variation in climatic conditions was a significant driver for crop composition and confounded the effects of rotation, variety choice, fertilization and crop protection [13,58]. For example, for winter wheat, RDA of data from four growing seasons confirmed that both climatic conditions and agronomic parameters were significant explanatory variables/drivers for leaf phenolic concentrations (Figure 12).…”

“…It is important to note that the inclusion of energy crops in organic rotations, and the use of digestate from on-farm biogas units as fertilizer, has provided an alternative nutrient recycling option, especially for stockless organic producers [30,[48][49][50]. Moreover, the use of biogas units for manure processing on mixed organic farms is thought to minimize N-losses, since both nitrification and denitrification are inhibited during the anaerobic digestion process [48][49][50].…”

“…regimes may have also contributed to differences in phytochemical concentrations and antioxidant activity levels between organic and conventional crops [7,12,13,19,50,51,53,[57][58][59][60] (Table 1; Figure 3; Section 2.3).…”

“…Differences in the N-supply pattern from organic and mineral N-fertilizer are also thought to, at least partially, explain the results of (i) the NFSC trials, and (ii) recent systematic reviews/meta-analyses and retail surveys that reported higher levels of antioxidant activity and concentrations of phytochemicals with antioxidant activity in organic crops, compared with conventional crops [56][57][58][59][60]. However, previous studies and the NFSC trial results demonstrated that rotation design, variety choice and crop protection regimes may have also contributed to differences in phytochemical concentrations and antioxidant activity levels between organic and conventional crops [7,12,13,19,50,51,53,[57][58][59][60] (Table 1; Figure 3; Section 2.3).…”

The environmental and biodiversity benefits of organic farming are widely recognized, but there is still controversy about the effects of organic production methods on the nutritional composition of food and human health. In the first part of this article therefore, we critically review the evidence that organic farming methods improve the nutritional quality of food crops. Moreover, we summarize our current understanding of how quality gains are linked to the implementation of the “innovations” introduced into conventional crop production during the intensification or “green revolution” of agriculture over the last 100 years. In the second part of the article, we critically review the evidence for the range of health benefits related to organic food consumption. Specifically, we describe and discuss the results from: (i) dietary intervention studies which have found that organic food consumption substantially reduces pesticide exposure in humans and affects feed intake, growth, hormone balances and immune system responsiveness in animal models; (ii) human cohort/epidemiological studies which have reported significant positive associations between organic food consumption and the lower incidence of a range of diseases including obesity, metabolic syndrome, cancer, hypospadias, pre-eclampsia, eczema and middle ear infections in infants; (iii) interactions and trade-offs between diet (e.g., whole-grain, fruit and vegetables and reduced red-meat consumption) and food types (organic versus conventional) concerning public health and future food security. The article also identifies knowledge gaps and highlights the need for (i) long-term, factorial field experiments to understand the relative effects of agronomic and pedoclimatic drivers on crop quality and safety, and (ii) clinical trials and additional human cohort studies to confirm the positive health outcomes linked to organic food consumption. The main conclusions from our review are that there is growing evidence that (i) agricultural intensification has resulted in a reduction in the nutritional quality of food and the sustainability of food production, and (ii) organic farming practices not only improve food quality and human health, but also food security. This is particularly true where current nutritional guidelines (increasing whole-grain, fruit and vegetable products, while reducing red-meat consumption) are implemented.

“…Relative to the common wheat, spelt has a lower harvest index and a lower N harvest index, which indicates a lower proportion of assimilates and nitrogen in the grain (Koutroubas et al, 2012). An advantage of spelt over the common wheat stems from its ability to achieve a high protein content with a small amount of fertilizer (Magistrali et al, 2020;Fatholahi et al, 2020). The cultivation of spelt does not require a large amount of nutrients.…”

The aim of this study was to determine the effect of fertilization with organic fertilizers Fertil Supernova and Ilsamin N90 on the yield and yield components of three spelt varieties. The study was conducted on an anthropogenized eutric cambisol at the experimental site of the Faculty of Agriculture in Zagreb during 2015/16, 2016/17, and 2017/18, respectively. The study included three varieties of spelt, Nirvana, Ostro, and Bc Vigor, as well as a topdressing with organic fertilizers and a control (without topdressing). The first topdressing at the beginning of spring vegetation consisted of the application of organic fertilizer Fertil Supernova in the amount of 300 kg ha-1, while the second topdressing at the end of tillering consisted of a foliar application of Ilsamin N90 in the amount of 3 l ha-1. The spelt yield and its yield components were significantly influenced by weather conditions, primarily by the amount and distribution of precipitation. The studied spelt varieties did not significantly differ in the grain yield. In all three research years, the variety Nirvana has achieved the significantly largest number of ears per m2. Topdressing with organic fertilizers had a positive impact on the yield of the hulled spelt grain only in the dry year of 2016/17. Topdressing with organic fertilizers did not have a significant impact on the yield components.

Quinoa (Chenopodium quinoa Willd.) is attracting interest as a key contributor to global food and nutritional security. This study evaluated the effects of and interactions between sowing date (mid-April vs. early May) and variety ('Atlas' and 'Jessie') on the performance of quinoa in northeast England over three seasons (2016)(2017)(2018). Grain yield was about 1 Mg ha −1 on average across all treatments, associated with poor crop establishment (56.6%) and a prolonged crop growth cycle (165 d). The highest grain yield of 1.70 Mg ha −1 was achieved from the late-maturing variety Atlas in 2017, which was also supported by the highest harvest index and yield components. Grain yield, protein content, and Zn concentration were all significantly higher for the late sowing, whereas total antioxidant concentration was significantly higher in response to the early sowing date. Grain Zn (43.8 mg kg −1 ), Fe (123.1 mg kg −1 ), and protein (13.4%) concentrations were higher on average than those reported for major cereals with particularly high protein (14.8%) and Zn (63.8 mg kg −1 ) concentrations achieved in 2017. Despite the relatively low yield, varietal differences in crop yield and development can be targeted for future crop improvements to suit the cool temperate climate of northeast England. INTRODUCTIONQuinoa (Chenopodium quinoa Willd.) has been identified by the Food and Agricultural Organization of the United Nations as one of the crops destined to offer food security in the next century and the year 2013 was designated as the International Year of Quinoa because of its potential contribution to sustainable food production . Quinoa grain has a range of nutritional benefits, including its gluten-free status, low glycemic index, and good balance of essential amino acids, fiber, lipids, carbohydrates, vitamins and minerals, which are increasing the demand for quinoa products globally (Alvarez-Jubete et al., 2010; Angioloni & Abbreviations: HI, harvest index; TGW, thousand-grain weight.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
