The potato tuber content of microelements as affected by organic fertilisation and production system

Abstract

The objective of the work was to determine the effect of undersown catch crops, which were either autumn-incorporated or left on the soil surface as mulch for spring incorporation, on the microelement content in the tubers of potato cultivated in the integrated and organic production system. Field research was conducted at the Zawady Experimental Farm owned by Siedlce University of Natural Sciences and Humanities, Poland (52° 03′ 39″ N, 22° 33′ 80″ E). The following two factors were examined in the study: (i) organic fertilisation, control, farmyard manure, serradella, westerwolds ryegrass, serradella applied as mulch and westerwolds ryegrass applied as mulch and (ii) production system, organic and integrated. Microelements (B, Cu, Fe, Mn, Zn) were determined in potato tubers samples. The tubers of potato manured with autumn-incorporated serradella had the highest iron and zinc contents, whereas tubers following autumn-incorporated serradella and spring-incorporated serradella mulch had the highest boron content. Manuring with undersown catch crops and farmyard manure contributed to a decline in the potato tuber content of copper and manganese. Potato cultivated in the integrated production system contained more copper, manganese and zinc, whereas organic tubers had more iron and boron.

Analysis of Total Phenols, Sugars, and Mineral Elements in Colored Tubers of Solanum tuberosum L.

“…The zinc concentration varied from 9.8 to 26.0 mg/kg of DW, matching with previous results of fertilized and organic Zn concentrations [ 5 , 31 , 32 ]. The concentrations did not vary depending on the flesh coloration of the tuber, but the purple sweet potato tuber had a significantly lower Zn concentration of only 8.2 mg/kg of DW.…”

“…In general, higher magnesium levels were detected in the tubers of cross-breeds of Blue Congo and Granola. The overall levels varied from 629 to 1264 mg/kg of DW with an average of 1015 mg/kg of DW, which is comparable to both conventional and organically cultivated potato tubers, that averaged from 1183 to 1646 mg/kg of DW [ 5 , 32 ].…”

Heritability and genetic gains for iron and zinc concentration in diploid potato

“…The mean iron content of potato tubers in Acco is significantly ( P < .01) higher than that in Huancayo. This could be due to the high iron content of the soils of Acco, coinciding with expectations that the availability of iron and zinc is greater with lower pH and higher organic matter content of soils (Gąsiorowska, Plaza, Rzążewska, Cybulska, & Górski, 2018; Lindsay, 1991; Rengel, 2015).…”

“…The concentrations of mineral elements and DM in potato tubers and tuber size are influenced by environmental, developmental, and management practices, which can interact with each other and with genetic factors. (Gąsiorowska et al., 2018; Kromann et al., 2016; White et al., 2012). While further research is needed to better understand relationships between these characteristics, experiments with the application of mineral fertilizers by White et al.…”

Influence of Agricultural Management Practices on the Soil Properties and Mineral Composition of Potato Tubers with Different Colored Flesh

“…In Poland, in a recent study conducted by Wierzbowska et al [38], organically grown potatoes had a higher content of B (8.6-8.9 mg kg −1 ) and Cu (2.8-3.1 mg kg −1 ), and a lower content of Fe (47.0-47.1 mg kg −1 ), Mn (6.0-6.4 mg kg −1 ), and Zn (11.9-12.2 mg kg −1 ) than potatoes grown in conventional systems. Gąsiorowska et al [39] reported that potatoes cultivated in the integrated production system contained more Cu, Mg, and Zn, whereas organic tubers had more Fe and B.…”
