“…Regarding the lifting chain, it usually consists of two stages of cleaning. Chain's vibration and impact, with the lifting chain rod, are the main method of the lifting chain to separate the soil from the tuber [56][57][58][59][60]. When combined with the vibrator, the lifting chain will produce a wider vibration amplitude, which can enhance the cleaning effect [61].…”

Root crops grow in the soil deeply and bond with soil closely, which results in that the process of the separation between soil and root becomes the most difficult during the harvesting processes. In order to harvest root crops efficiently, the mechanical harvesting has become the main developing trend. However, high power and high damage rate are still occurred when mechanical harvester gets in touch with the roots. In this paper, we review the research of the development and evaluation of the mechanical harvesting of root crops and its performance optimization on the past years. The process of soil separation mainly consists in the initial separation between root and the ground and further separation between root and adhered soil. In general, the soil-cutting operation in the initial separation and the sieving mechanism in the further separation require high draught and power. And the dramatic friction, impact, pressure and so on, which happen in the components and soil-roots, are the key reasons to lead to root damage. The optimization of harvesting methods and parameters, including the digging shovel shape, working conditions, vibration, and screening way, is more significant in improving the harvesting performance. But there are still some limitations in the research and application of the mechanical harvester for root crops. Future research is suggested to focus on the development of the soil break-up when the digging shovel cutting soil, the insight into the interaction between soil and roots by different external compression loads, and the long-term studies to verify the high-efficiency and low-damage performances of mechanical harvester in practical application.

“…On the other hand, Salces et al (2000) reported that leaf of the foliage dry matter ranged from 60 -66%, stem from 12 -15%, and petiole from 20 -28% when cassava plants were defoliated at 4 -5 mo after planting. Sweetpotato vines can reach 1 -7 m in length which are mostly returned to the field after harvesting, causing huge waste (Mu et al 2022).…”

This study was conducted to determine the physico-chemical characteristics of ensiled cassava (Manihot esculenta Crantz) and sweetpotato (Ipomoea batatas L. (Lam.)) foliage with or without additives molasses and rice bran. Six treatment combinations were from two crop species (cassava and sweetpotato) and three additives (without additive, 10% molasses, and 10% rice bran). The physical (color, odor, texture) and chemical characteristics (pH, total soluble sugars, Flieg point, dry matter, organic matter, ash, crude protein, NDF, ADF, hemicellulose) of the samples were evaluated following standard procedures. Fermentation kinetics of cassava foliage silage and ruminal in situ DM degradability of cassava foliage silage were evaluated for 3, 6, 12, 24, 48, and 72 h using cannulated cattle. Results showed that cassava foliage (CF) and sweetpotato foliage (SF) silages with molasses had the lowest pH of 3.82 and 3.80, respectively due to high TSS values of the samples. CF had the highest crude protein (19.06%) compared to SF silage (11.61%). Moreover, CF had low fiber fractions (NDF and ADF) resulting in a high effective dry matter degradability (74.73%) of the silage. Results on silage quality, nutritive value, and dry matter degradability evaluation proved the potential of cassava foliage silage with molasses as an alternative high protein feed for ruminants.

IntroductionThe efficiency of potato production depends to a large extent on the production of quality seeds that meet the requirements of the growing region. The main component of this production includes breeding, which creates the genetic basis of seeds. The process of establishing patterns between the amount of fertilizer application (“Aquarin 12,” “Bona Forte,” “Osmocote Exact High K”), their type, and biometric characteristics of potato plants of the studied varieties “Guliver,” “Beauty of Meshchera,” and “Grand” was explored.MethodsDuring the experimental studies, the methods of variation statistics, the technique of field experiment with the corresponding transformations to achieve normal distribution, and subsequent dispersion analysis were used.ResultsThe results of the research on the evaluation of potato structural elements depending on the plant nutrition system of the studied varieties testify to the expediency of using nutrient solutions in potato cultivation irrespective of their type. In addition, it has been established that increasing the concentration of the nutrient base solution from 75 to 125% of the nutrient formula improves the quality indicators of minitubers, namely the content of starch, sugars, dry matter, crude protein, phosphorus, specific gravity, and ash content, which can contribute to obtaining high-quality potatoes.DiscussionThus, the use of morphological and physiological tools in closed ecosystems is informative for predicting key agricultural characteristics of potato plants. Additionally, integrating organic amendments and biofertilizers, as supported by other studies, could further enhance nutrient uptake and plant health, especially under conditions of low irrigation.
