Mechanization of agriculture

The most important types of abiotic stress that affect agricultural crops throughout the world are drought and salinity. These stresses will continue to worsen as the current climate crisis progresses. Plants have evolved a complex set of mechanisms in order to protect themselves from salt and drought. At the macrobiological level, these include alterations in growth rate, water balance, antioxidant defenses, and photosynthesis.

The present study evaluated the possible potential of amino acids in enhancing the salinity tolerance in spinach and identified the probable underlying mechanisms. The experiment comprised of two factors viz. amino acids with total of seven treatments; control, salinity (sal) 100 mM, Methionine + sal, Phenylalanine + sal, Proline + sal, Tyrosine + sal, Combined amino acids + sal, and two spinach cultivars (Desi Palak and VRI-2019).

Cherry laurel is one of the most important cherry species and naturally grown in Black sea region in Turkey. Its fruits are sold at high price in local markets in northern parts of Turkey. Cherry laurel fruits are very perishable with a limited shelf life due to a high metabolic activity and susceptibility to mechanical damage and microbial attack. The effect of edible coatings (EC) based on caseinat, Semperfresh and lecithin on the fruit quality, bioactive content and antioxidant activity of cherry laurel fruits stored at 4 ± 1 °C for 15 days was evaluated.

"Evaluation of gene expression levels in grapevine cultivars after Erysphe necator and methyl jasmonate treatments" analyses concluded that the susceptible and tolerant cultivars utilized different mechanisms and that TF genes were induced in the presence of PM and MeJa. It was determined that PM showed different levels of expression in 3 genes and 4 cultivars. MeJa treatment had a stimulating effect on the response to E. necator infection.

In the present study, the physiological changes in aged cress seeds and seeds imbibed under different temperatures after aging were examined. In this regard, an array of analysis concerned with the cell membrane leakages and seed viability was performed. For comparison, accelerated aged seed lots with high, intermediate and low viability were used, in relation to the control (not subjected to short-term imbibitions).

The study was established in the eastern Marmara Region of Turkey and included various SP techniques and cultural treatments (CT) of differing intensity applied in a factorial design before the plantation of one-year-old maritime pine seedlings. The SP treatments included raking by a bulldozer (SPB), raking by a bulldozer and then spraying with 1%-(v:v) glyphosate (SPH), and raking by a bulldozer followed by the broadcasting of the subsoil via bulldozer (SPS), the latter being the standard and the most intensive forest management SP treatment.

Affected by global economic pressure and epidemics, sustainable agriculture has received widespread attention from farmers and agricultural engineers. Throughout history, agricultural technology has closely followed the pace of scientific and technological development and has followed the footsteps of mechanization, automation, and intelligence to progress continuously. At this stage, artificial intelligence (AI) is dominating the field of agriculture and advancing the progress of sustainable agriculture.

Citrus production is declining worldwide due to several biotic and abiotic factors. The diseases caused by Phytophthora spp. present major economic risks since they are soil-borne and spread quickly if environmental conditions are favorable, or irrigation is poorly managed. Phytophthora species are present in all citrus-producing areas around the world causing significant losses in crop yield and affecting tree health.

Broccoli is rich in vitamins, antioxidants, minerals, free from calories and fat necessary for a healthy life. The production of broccoli is poor as compared to the developed world because of different biotic and abiotic stress. The nutritional stress is increasing with the passage of time because of low soil fertility and numerous stresses occur in the root zone of plants which reduce the uptake of minerals.

Design of new highly productive livestock breeds, well-adapted to local climatic conditions is one of the aims of modern agriculture and breeding. The genetics underlying economically important traits in cattle are widely studied, whereas our knowledge of the genetic mechanisms of adaptation to local environments is still scarce.

The study "Assessing the status of mechanization and proposing technical solutions for lime farming in the Mekong River Delta" was conducted to assess the current status of mechanization in lime growing activities of farmer households in the Mekong River Delta. The current status of mechanization was assessed through different groups of criteria that reflect the scale of mechanization level, resources of farmers applying mechanization, results, and production efficiency.

This paper aims at analyzing the situation of land accumulation and concentration in Vietnam in the current circumstance both in theoretical and practical aspects. Since land accumulation and concentration create favorable conditions for mechanization for the moving of the agricultural sector towards a commodity production model, it faces multiple challenges in practices under a variety of forms of accumulation and concentration.

Worldwide feralization of crop species into agricultural weeds threatens global food security. Weedy rice is a feral form of rice that infests paddies worldwide and aggressively outcompetes cultivated varieties. Despite increasing attention in recent years, a comprehensive understanding of the origins of weedy crop relatives and how a universal feralization process acts at the genomic and molecular level to allow the rapid adaptation to weediness are still yet to be explored.

Pigs are important animals for agricultural and biomedical research, and improvement is needed for use of the assisted reproductive technologies. Determining underlying mechanisms of epigenetic reprogramming in the early stage of preimplantation embryos derived from in vitro fertilization (IVF), parthenogenesis, and androgenesis will not only contribute to assisted reproductive technologies of pigs but also will shed light into early human development.

This finding suggests that over-promotion of export-oriented agriculture could leave smallholder farmers and disadvantaged populations in a vulnerable situation. Their food security could be enhanced by the conservation of community-based natural resources with respect given to the role of TEK.

The main mechanism of resistance in A. fumigatus involves incorporation of tandem repeats in the promoter region of cyp51A, along with point mutations in the gene sequence. Resistant isolates tend to arise either due to excessive use of azole fungicides in the agricultural fields, from where they reach human through sporulation; or by prolonged treatment of patients with azole drugs. The early diagnosis of aspergillosis is very crucial for successful treatment of a patient.

Post transcriptional gene regulation in wheat cultivars caused by boron (B) toxicity has not been reported to date. In this study, two wheat cultivars Bolal-2973 (B-tolerant) and Atay-85 (B-sensitive) were compared with regard to the transcriptional regulation of miR319, miR172 and miR398 and their plausible target genes in order to address differences in their performances under high B levels. The expression levels of Cu/ZnSOD gene were found to be greater in Atay exposed to toxic B compared to Bolal, as verified by stable expression level of miR398.
