“…Given that sunflower is the third oleaginous plant on the world market of oilseeds, with 45 million tons of grains per year, and that it occupies the fourth position in the vegetable oils market, the implementation of a sustainable growth technology in sunflower production is a necessity [31]. Given that sunflower is the third oilseed plant on the world oilseed market, high interest in oilseeds will lead to increased production and trade.…”

Impact of Reducing Fertilizers and Pesticides on Sunflower Production in Romania versus EU Countries

et al. 2022

The Farm-to-Fork strategy was the starting point for this study. Farmers in Romania and other member states expect a decrease in agricultural production in the main crops, due to the reduction of the quantities of fertilizers and pesticides allowed to be used. The article aims to highlight these quantities currently used, as well as the correlation with the realized productions, before the application of the mentioned strategy. The sunflower farming system was the object of the analysis, for which purpose the cultivated areas and the productions obtained in Romania were studied and compared to those in Germany, Spain, France, Italy, Hungary and Poland. It was found that in Romania, in the period 2010–2019, small amounts of fertilizers and pesticides were applied. Romania occupies the last position among the countries under analysis, both in terms of fertilizers and pesticides. To obtain a ton of sunflower in Romania, the nitrogen fertilizers used were 19.2 kg N active nutrient, with a negative deviation of −45.5 kg N active nutrient compared to Germany. The P2O5 phosphorus fertilizers used in Romania represent 7.48 kg of the active phosphorus nutrient with a negative deviation of −13.09 kg/ha compared to Spain. Potassium fertilizers used in Romania comprise 2.68 kg of active potassium nutrient used to obtain a ton of sunflower and have a negative deviation of −22.66 kg/ha compared to Poland. The pesticides used in Romania for sunflower cultivation represent 0.35 kg total pesticides used per ton and have a negative deviation of −2.48 kg compared to Spain, the largest consumer. In the event that a unit reduction of 50% for pesticides and 20% for fertilizers is applied, according to the Farm to Fork Strategy, the impact will be unequal on the productions obtained, both quantitatively and qualitatively.

“…Diversity at all levels, from genetics to the ecosystem, enhances the ability to crop systems to overcome and adapt to forthcoming changes [49]. It reduces interspecific competition by enhancing complementarity or facilitation processes thereby improving the exploitation of resources, which in turn reflected in the increase in plant production corresponding to greater efficiency of the agroecosystem as a whole [50].…”

“…Along with food safety, biodiversity supports healthy and nutrient-rich diets, enhances the efficiency of agroecosystems, and boosts resilience to changing environmental conditions, climate risks, and socioeconomic challenges [51][52][53]. Sunflower intercropping with alfalfa proved the most appropriate and stable yields than sole cropping [49]. Similarly, intercropping may contribute to the mitigation of climate change, for example, by reducing the need for fossil-based N fertilizer, mechanical weed control, and the associated N 2 O and CO 2 emissions [11].…”

One of the main challenges in the transition to more sustainable agriculture is designing and selecting agricultural systems that are stable and perturbation resistant. Crop diversification is now recognized as a decisive part of sustainable agroecological development. It is one of the crucial agroecological practices that prove ecosystem services such as nutrient cycling, biological N fixation, pest and disease regulation, erosion control, climate regulation, soil fertility maintenance, biodiversity conservation, and carbon sequestration. To maximize these desired outcomes, understanding, designing, and optimizing, the adoption of crop diversification is crucial for the sustainability of food production under low-input practices. One approach to building sustainable food security and optimal management systems for limited resources is through the application of crop simulation models in multi-cropping systems. Indeed, some models can be used to simulate intercropping systems such as DSSAT, APSIM, ALMANAC, STICS, and FASSET. Thus, the application of such powerful models provides an option to redesign crop mixtures in appropriate sowing proportion and sowing date to tackle the enormous challenges facing agricultural development. In this regard, this review intended to assess existing suitable model to simulate multiple cropping systems and its role in building resilient crop production and ecosystem services without damaging the environment. It also highlights the key role of crop diversity as an ecosystem service provider to guarantee plant productivity in emerging systems of sustainable agriculture.

“…Considering its adaptability to various climatic conditions, sunflower has been proposed as a global crop model for adaptation to different environments [8,9]. However, the increasing frequency of climate change, particularly droughts during critical phenophases, can lead to a significant reduction in sunflower yield stability [10,11]. As reported by Donatelli et al [12], a decline in sunflower yields ranging from 10% to 30% is anticipated in Eastern Europe by the year 2030.…”

Climate change projections for the 21st century pose great threats to semi-arid regions, impacting seed production and the quality of sunflowers. Crop yields are negatively affected by climate variability, especially in the event of droughts during the crucial growth stages. Understanding the relationships between agrometeorological, genetic, and agronomic factors is crucial for maintaining crop sustainability. Optimal sowing dates are an essential condition for maximizing crop genetic potential, but challenges come from annual weather variations. This study analyzes how sunflower genotypes respond to different sowing dates under climate change and focuses on the conditions for obtaining maximum seed yields and favorable agronomic traits. From 2020 to 2022, the experiment featured six genotypes sown across four different dates at two-week intervals, simulating seed sunflower production. The results obtained by ANOVA indicated that the seed yield and oil yield were significantly affected by the sowing date, the genotype, and their interaction, with coefficients of variation ranging from 7.6% for oil yield to 41.1% for seed yield. Besides seed yield and oil yield, LDA biplot and Discriminant Functions confirmed that seed germination energy also played a significant role in separating genotypes into clusters. A Visual Mixed Model showed that shifting the optimal sowing date (mid-April) to early May allows a reduction in the number of days the plants spend in critical growth stages, thereby escaping stressful conditions during pollination and seed filling. The findings resulted, on average, in increased yields and improved seed quality, which are the primary goals of seed production, but not in increased 1000-seed weight. Notably, high temperatures during the critical sunflower growth stages negatively affected the measured parameters of seed production. The increased precipitation during seed filling boosted the 1000-seed mass and seed yield. Extended flowering reduced the growth rate and seed germination, but longer seed filling increased the 1000-seed mass and seed yield. Our future breeding goals will be to create genotypes with a shorter flowering period and an extended seed-filling period to better respond to climate change.
