Abstract

Sunflower (Helianthus annuus L.) is a globally prominent oil seed. Sulfur is a vital nutrient that plays a crucial role in the growth and development of crop plants. Compared with other crops, oilseed crops require more sulfur for their role in oil biosynthesis and as an essential constituent of amino acids, vitamins, proteins, and enzyme structure. Its deficiency results in poor utilization of NPK and, ultimately, crop reduction in yield and quality. Hence, the study investigated the effect of different levels of sulfur on the harvest and quality attributes of various sunflower hybrids. The experiment comprised four sulfur levels (0, 20, 30, 40, and 50 kg per ha) and four sunflower hybrids coded as C124 × RH344, C112 × RSIN82, C116 × RH344, and C208 × RH445. The recorded data underwent analysis statistically using Fisher’s analysis of variance technique, and treatment means comparison followed Tukey’s honest significant difference test (HSD) at a 5% probability level. The results showed maximum plant height at maturity (75.80 cm), head diameter (17.90 cm), leaf area per plant (2,309.21 mm2), 100-achene weight (10.60 g), achene yield (2,806.61 kg ha-1), harvest index (26.58%), and oil content (48.46%), while minimum days to flower initiation (40.33 days) were evident when sowing hybrid C124 × RH344 with an application of 20 kg per ha sulfur.

施硫可提高向日葵的产量和品质。混合动力车

向日葵(Helianthus annuus L.)是一种全球知名的油料种子。硫是一种重要的营养物质，对作物的生长发育起着至关重要的作用。与其他作物相比，油籽作物在油脂生物合成中需要更多的硫，作为氨基酸、维生素、蛋白质和酶结构的必需成分。氮磷钾缺乏导致氮磷钾利用率低下，最终导致作物产量和品质下降。因此，本研究探讨了不同硫含量对向日葵杂交种收获和品质性状的影响。试验采用4个硫水平(每公顷0、20、30、40和50 kg)和4个向日葵杂交品种，分别编号为C124 × RH344、C112 × RSIN82、C116 × RH344和C208 × RH445。记录资料采用Fisher方差分析技术进行统计学分析，治疗手段比较采用Tukey诚实显著差异检验(HSD)，在5%概率水平上进行。结果表明，C124 × RH344在每公顷硫用量为20 kg时，成熟株高(75.80 cm)、穗粗(17.90 cm)、单株叶面积(2,309.21 mm2)、百瘦果重(10.60 g)、瘦果产量(2,806.61 kg ha-1)、收获指数(26.58%)、含油量(48.46%)最大，开花最短天数(40.33 d)最大。

期刊介绍： The SABRAO Journal of Breeding and Genetics is an international journal of plant breeding and genetics research and was first published in 1969. It is the official publication of the Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO). Its objectives are to: promote the international exchange of research information on plant breeding and genetics, by describing new research findings, or ideas of a basic or practical nature; and be a medium for the exchange of ideas and news regarding members of the Society. The Journal gives priority to articles that are of direct relevance to plant breeders and with emphasis on the Asian region. Invited for publication are research articles, short communications, methods, reviews, commentaries, and opinion articles. Scientific contributions are refereed and edited to international standards. The journal publishes articles for SABRAO members mainly. The Journal preferred strongly that at least one author should be a current member of the Society. Non-members may also publish in the journal.
