摘要

农业是苏丹经济的重要组成部分,是经济增长、减贫和可持续发展的支柱。向日葵已成为苏丹农民和消费者的重要作物,非常适合当地的种植制度,被认为是该国最重要的经济作物。本试验在苏丹卡萨拉大学(New Halfa)实验农场为研究品种和种植间距对向日葵(Helianthus annuus L)植株生长和产量的影响,采用2个品种(pannar-735和Damazin-1)和3个种植间距(10 cm、20 cm和30 cm)。处理采用全因子随机区组设计(RCBD),分为3个重复。结果表明,pannar- 735早熟,百粒重、单盘种子数、产量(g/株)和最终产量(3.00 t /ha)均显著高于其他品种。行距为30 cm时,茎粗粗、单穗种子数、百粒重、单株种子产量和最终种子产量(3.34 t /ha)最高。研究表明,在苏丹东部新哈法地区,向日葵杂交种pannar-735株距为30 cm时最适宜。

Response of Sunflower (Helianthus Annuus L) to Plant Spacing
Agriculture is an important sector of Sudan economy and is the backbone of growth, poverty reduction, and sustainable development. Sunflower has become an important crop for both farmers and consumers in Sudan, fits well in the local cropping system and is considered the most important cash crop of the country. The experiment was conducted in the Experimental Farm, University of Kassala (New Halfa) of Sudan, to investigate the influence of cultivars and planting Spacing on plant growth and yield of Sunflower (Helianthus annuus L). It consisted of two cultivars (pannar-735 and Damazin-1) and three plant spacing’s (10 cm, 20 cm and 30 cm). Treatments were arranged in a factorial randomized complete block design (RCBD), in three replications. The results revealed, the cultivar, pannar- 735, early flowering, significantly highest hundred seed weight, seeds number per disc, seed yield (g/plant) and final yield (3.00 ton/ha). The Intra-row spacing of 30 cm had a thicker stem diameter, a highest number of seeds per head, 100-seed weight, seed yield per plant and final seed yield (3.34 ton/ha). The study revealed that the sunflower hybrid pannar-735 and plant spacing 30 cm apart is the best for New Halfa Eastern of Sudan.
