Abstract

Given that climate change is a burning issue, agriculture must turn to more sustainable and environmentally friendly systems, counting intercropping. Within a two-year study of intercropping sunflower with legumes, the influence of this system on sunflower plant height and head diameter was investigated. The aim of research was to evaluate the effects of sunflower-legume intercropping on these traits, considering the possibility of competition between crops. The field trial was set up in April 2017 and 2018 at Institute of Field and Vegetable Crops, Novi Sad, Republic of Serbia experimental field in moderate-continental climate. Year 2017 was extremely arid with the sum of precipitation different compared to 2018. Plant height and head diameter of hybrids Rimi PR, Dukat and NS Gricko, intercropped with common vetch, red clover and alfalfa were compared with control, i.e. same sunflower hybrids grown as a sole crop. It was observed that intense growth of common vetch suppressed the growth of sunflower, and led to a decrease in measured traits in all three hybrids. Results indicated that the following combinations of sunflower and legumes are most desirable: NS Gricko/RC, Dukat/ALF, Dukat/RC and Rimi PR/ RC depending on the agro-ecological conditions. Given that the experiment was performed in years that varied significantly in agro-ecological conditions, the results indicated that red clover and alfalfa can mitigate the negative effects caused by lack of precipitation and high temperatures. In order to better understand all aspects of sunflowerlegume intercropping, further research, which should include other morphological, qualitative and quantitative indicators, is needed.
向日葵与豆科植物间作对向日葵某些形态性状的影响
鉴于气候变化是一个亟待解决的问题,农业必须转向更可持续、更环保的系统,包括间作。在为期两年的向日葵与豆科植物间作试验中,研究了间作制度对向日葵株高和穗粗的影响。本研究的目的是在考虑作物间竞争可能性的情况下,评价向日葵-豆科作物间作对这些性状的影响。该田间试验于2017年4月和2018年4月在塞尔维亚共和国诺维萨德大田和蔬菜作物研究所进行,试验田为中大陆性气候。2017年极端干旱,降水总量与2018年不同。比较了与紫薇、红三叶草和紫花苜蓿间作对照的Rimi PR、Dukat和NS Gricko 3个向日葵杂交种的株高和穗粗。结果表明,紫薇的强烈生长抑制了向日葵的生长,并导致3个杂交种的测量性状下降。结果表明,根据不同的农业生态条件,向日葵和豆科植物最适宜组合为NS Gricko/RC、Dukat/ALF、Dukat/RC和Rimi PR/ RC。考虑到试验是在农业生态条件变化较大的年份进行的,结果表明,红三叶草和紫花苜蓿可以缓解降水不足和高温带来的负面影响。为了更好地了解葵花豆科作物套作的各个方面,还需要进一步的研究,包括其他形态学、定性和定量指标。
