“…However, other factors (SD and the interaction between SD and G) also exhibited a statistically significant effect, as confirmed by Krstić et al [42]. Environmental conditions, genotype, and applied agronomic practices have a substantial impact on seed and oil yield variation, as reported by Ion et al [43], Kvashin et al [44], and Radić et al [45]. Furthermore, different factors exhibited varying effects on Y and OY during different years of the study.…”

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.

“…Hladni et al (2014) argues that there is a significantly high degree of variability in seed yields between inbred sunflower lines. The external environment has a great influence on the variability in sunflower seed yields (Radić et al, 2020), as well as the genotype itself (Kvashin et al, 2018). In addition to genetic factors (the genotype), sunflower seed yields are also conditioned by cultural practices applied and environmental conditions.…”

Summary As plant breeding is a very complex and sophisticated process, it is of paramount importance to understand the nature and magnitude of interdependence between specific plant features. Using PCA and correlation analysis, this study examined the variability in features of two types of inbred sunflower lines and determined its connection with their seed yields. The experiment was conducted as a randomized complete block design with four replications in Rimski Šančevi (the experimental field of the Institute of Field and Vegetable Crops in Novi Sad) in 2018 and 2019. It examined a total of nine inbred sunflower lines created at the Institute of Field and Vegetable Crops in Novi Sad. The results obtained suggest a high degree of variability in the examined traits of inbred sunflower lines considered, whereas the significance indicated by the F test was confirmed by the Duncan test performed. A high degree of variability was also found between the different types of inbred lines considered. A positive correlation was found between all four traits observed in the inbred sunflower lines considered, with different levels of significance. A statistically significant positive increase in the head diameter was followed by an increase in the weight of 1000 seeds, which generated a higher seed yield per unit area. According to the arrangement of different types of inbred lines considered on the PCA biplot, it can be concluded that the linoleic inbred lines G7L and G8L had the highest average values of the 1000-seed weight, head diameter and seed yield throughout the course of both experimental years. The useful data obtained by PCA analysis can facilitate successful selection programs aimed at developing sunflower genotypes that possess high stability and seed yields.

“…Perkecambahan benih tanaman bunga matahari sangat dipengaruhi oleh suhu dan ketersediaan air, pada suhu 25-35 o C dengan perlakuan pemberian air setiap hari menghasilkan perkecambahan benih bunga matahari yang baik dan sehat (Shaheen et al, 2014). Selain hal tersebut, persentase perkecambahan dari benih bunga matahari juga dapat dipengaruhi oleh faktor genotip, dan juga sangat ditentukan oleh interaksi diantara genotip dan lingkungan tumbuh (Radić et al, 2020). Perlakuan perendaman terhadap benih bunga matahari ke dalam GA3 berkonsentrasi 500 ppm dapat meningkatkan persentase perkecambahan sebesar 80% (Adams dan Tebeest, 2016).…”

Program pengabdian masyarakat ini berupa pelatihan teknologi budidaya tanaman bunga matahari di kelompok tani Desa Bokor. Kegiatan ini bertujuan untuk meningkatkan keterampilan teknologi budidaya tanaman bunga matahari di kelompok tani, dan memberikan pemahaman dan meningkatkan partisipasi masyarakat untuk membudidayakan tanaman bunga matahari. Program tersebut dilatarbelakangi oleh rencana desa untuk mengembangkan desa ke arah desa wisata. Keberadaan bunga matahari dapat menambah daya tarik dan nilai estetika lingkungan, sehingga dapat menarik wisatawan untuk berkunjung ke desa. Hal ini secara tidak langsung dapat meningkatkan kesejahteraan masyarakat dan menciptakan lapangan kerja baru. Kegiatan pengabdian telah dilaksanakan dari bulan Juli - November 2020 di Desa Bokor Kabupaten Malang. Metode pelaksanaan adalah metode Training of Trainer (TOT). Tahapan metode pengabdian yang dilakukan meliputi perencanaan, persiapan, pelaksanaan kegiatan, monitoring dan evaluasi. Tim pengabdian masyarakat melakukan monitoring secara daring dan luring/langsung turun ke lapangan, untuk melihat langsung kondisi tanaman dan berkomunikasi sekaligus berdiskusi dengan perwakilan petani. Di akhir kegiatan pengabdian, tim pengabdian juga melakukan pemberian bantuan benih tanaman bunga matahari yang bermutu tinggi. Hasil program pengabdian yaitu telah meningkatnya keterampilan teknologi budidaya tanaman bunga matahari di kelompok tani Desa Bokor, pemahaman dan partisipasi masyarakat untuk membudidayakan tanaman bunga matahari juga meningkat
