Effects of stocking density on the performance of lettuce (Lactuca sativa) in small‐scale lettuce‐Nile tilapia (Oreochromis niloticus L.) aquaponic system

open access: yesAquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 458-469, December 2022., 2022
Graphical Abstract : Aquaponics, hydroponics, stocking density. Abstract Aquaponics incorporates aquaculture with hydroponics, whose principles and operations largely remain untested. Currently, there is a knowledge gap on the performance of aquaponic systems used for fish production under different stocking densities.

Effects of fused and blended fertilizers on maize yield and soil properties

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3429-3444, November/December 2022., 2022
Abstract The deficiency of secondary and micronutrients negatively affects plant metabolic functions and reduces crop yields. These nutrients are applied in small quantities (<10 kg ha−1) and are physically blended or chemically fused with primary nutrients to enhance uniformity of application.

Dependence of chlorophyll content in leaves from light regime, electromagnetic fields and plant species [PDF]

open access: yesJOJ Hortic Arboric. 2020; 3(1): 555602, 2020
The regularity of the distribution of chlorophylls content in a series of 30 cultivated plants and 75 steppe grasses was studied. The increased content of chlorophyll and magnesium in vegetables and grains compared with greens and steppe grasses is associated with more complex genetics of metabolism, which has stages of flowering and fruiting.

Maize–soybean intercropping: A bibliometric analysis of 30 years of research publications

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3377-3388, November/December 2022., 2022
Abstract Maize (Zea may L.)–soybean [Glycine max (L.) Merr.] intercropping is popular in many countries because of its high productivity. However, no studies have explored maize–soybean intercropping via bibliometric methods. Taking the Web of Science database, the visualization applications of CiteSpace and VOSviewer were used to visually analyze the ...

Comparison of plant proximal sensing approaches for nitrogen supply detection in crops

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3317-3328, November/December 2022., 2022
Abstract Nondestructive proximal sensors can be an efficient source of information of N status in crops for localized and rapid adjustment of fertilization applications. The aim of this study was to compare two transmittance/reflectance‐based sensors (SPAD, ASD) and a florescence‐based sensor (Multiplex) in their ability to measure N content in corn ...

Downy mildew resistance and genetic variability in a wild rocket germplasm collection

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3083-3095, November/December 2022., 2022
Abstract One hundred accessions of a “core collection” of Diplotaxis tenuifolia (L.) DC. and Eruca spp. were screened at seedling stage for resistance to downy mildew. Accessions tested at the seedling stage were assigned to 0–6 interaction phenotypes.

Yield estimation of summer maize based on multi‐source remote‐sensing data

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3389-3406, November/December 2022., 2022
Abstract Accurately estimating regional‐scale crop yields is substantial in determining current agricultural production performance and effective agricultural land management. The Yuncheng Basin is an important grain‐producing area in the Shanxi Province. This paper used Sentinel 2A with a spatial resolution of 10 m and MODIS with a temporal resolution

The relationship between chlorophyllous spores and mycorrhizal associations in ferns: evidence from an evolutionary approach

open access: yesAmerican Journal of Botany, Volume 109, Issue 12, Page 2068-2081, December 2022., 2022
Abstract Premise Approximately 14% of all fern species have physiologically active chlorophyllous spores that are much more short‐lived than the more common and dormant achlorophyllous spores. Most chlorophyllous‐spored species (70%) are epiphytes and account for almost 37% of all epiphytic ferns.
