Effects of depth-dependent irrigation regimes and organomineral fertilizers on water use and quality attributes of sugar beet

Abstract

Experiments were conducted under provincial conditions of Kayseri, Turkey, for two years in the growing seasons of 2014 and 2015 to determine the effects of irrigation water applications based on different sugar beet root zone depths and different organomineral fertilizers on sugar beet yield, root quality, water consumption, and water use efficiency. Two constant root depths (D 1 = 0.9 m and D 2 = 0.6 m) and one active water extraction root depth (D 3 = 0.4-0.9 m) were investigated. A mineral fertilizer (F 1), an organomineral fertilizer (F 2), and organic + mineral fertilizer (F 3) were considered as the subtreatments in the experiments carried out in a completely randomized block split-split plots design with 3 replications. Despite the lower nitrogen and phosphorus quantities applied, the F 2 treatment produced the same sugar beet root yield (95.31 t/ha) as F 1 (88.59 t/ha) and F 3 (94.56 t/ha) treatments. The irrigation water requirements of D 1 for two years were 22.8% and 27.6% greater than the D 2 and D 3 treatments, respectively. Irrigation water use efficiencies of D 2 and D 3 treatments were higher than D 1. Digestion and recoverable sugar percent and Na, K, and N contents of roots were not affected significantly by the treatments. Using organomineral fertilizers would offer various advantages for disposing of huge urban waste deposits and returning organic matter to agricultural areas. Use of active root water extraction depth or 0.60-m root depth for irrigation applications will also contribute to efficient use of water resources and improve the income of sugar beet farmers due to reduced irrigation costs.

Growth and nutrient responses of Betula platyphylla, Larix kaempferi, and Chamaecyparis obtusa to different application methods of solid compound fertilizer

“…Fertilization plays a crucial role in increasing nutrient availability and plant productivity (Ryan, 2008;Ünlükara, 2019;Aung et al, 2020). However, the improper use of chemical fertilizer can put our natural environments at high risk due to leaching and surface runoff, especially in high-rainfall areas (Castillo, 2010;Stipešević et al, 2019;Nadkarni and Wheelwright, 2000).…”

How much of morphological variability in pollen from genus Rubus L. might be explained by climate variability

“…small-sized), with tricolporate or tricolpate pollen grains and mostly striate exine ornamentation (Nazeri 2008;Polyakova and Gataulina 2008;Wrońska-Pilarek and Jagodziński 2011;Wrońska-Pilarek et al 2013, 2019Lechowicz et al 2020). Moreover, intra-generic studies indicated that pollen grains were so similar that usually it was possible to distinguish only a few sections or series and from a few to several individual species, and most often there were groups of taxa with similar pollen characteristics.…”

“…Other genera of the Rosaceae family (e.g. Spiraea, Rosa, and Crataegus) showed a greater correlation between pollen morphology and infrageneric taxonomic classification (Wrońska-Pilarek and Jagodziński 2011;Wrońska-Pilarek et al 2013, 2019. In Rubus this may be the result of apomixes, that is the replacement of the normal sexual reproduction by asexual reproduction, without fertilization, which could reduce natural variability (Weber 1996;Zieliński 2004).…”

“…They are the non-living components of the environment. They also affect plant adaptation (Eyduran et al 2015;Unlukara 2019;Marsic et al 2019).…”

Phenotypic diversity in mutagenized population of urdbean (Vigna mungo (L.) Hepper)

“…Crop plants are genetically very diverse groups grown in temperate, subtropical and tropical regions and have been recognized for their human health benefits by containing high contents of non-nutritive, nutritive and bioactive compounds such as flavonoids, phenolics, sugars, essential oils, minerals etc ( Zia-ul-Haq et al., 2014 ; Oktem, 2019 ; Unlukara, 2019 ). Urdbean ( Vigna mungo (L.) Hepper) is an important rainfed short duration legume crop of India and is considered as an excellent source of high-quality dietary protein with good digestibility.…”
