Nitrogen (N) is the most limiting nutrient for production of vegetable crops, but anthropogenic sources pose risks due to its transformation into several reactive forms and movement throughout environment. The bulk N research date improve Use Efficiency (NUE) has followed a reductionist factorial approach focused on synthetic application rates crop growth response, under monocultures. increased adoption diversified cropping systems, organic sources, alternative management practices makes it more challenging unravel form transformation, movement, uptake dynamics, in time space. Here, based selected review recent literature, we propose holistic highlight key variables as well multilevel system, genetic, environmental, ecological, socioeconomic interactions cycle NUE. best strategies NUE include both inorganic rate calibration studies, germplasm selection, rotations, identification x interactions, pest water management. Agroecological that may vegetational diversification space, integrated crop–livestock conservation tillage, amendment inputs, legume-based landscape

Water consumption, soil nitrate-nitrogen residue and fruit yield of drip-irrigated greenhouse tomato under various irrigation levels and fertilization practices

Agricultural Water Management, Год журнала: 2022, Номер 277, С. 108092 - 108092

The excessive irrigation and chemical fertilizer application in the greenhouse can lead to resources waste, environmental pollution instable or even reduced fruit yields. A four-season experiment was conducted with three levels (W1, 100%ETc; W2, 75%ETc; W3, 50%ETc, where ETc crop evapotranspiration) five fertilization practices (CC, chicken manure fertilizer; SO, only soluble organic SC, SOSC, CK, a control no fertilizer) explore their integrated effects on growth, water consumption, soil nitrate-nitrogen residue yield of drip-fertigated tomato. results showed that root shoot ratio autumn (3.21 ×10−2) greater than spring (2.05 ×10−2). Fruit dry matter had most significantly positive relationship both seasons; however, leaf matter, stem SPAD autumn. average over four growing seasons 70.68, 67.16 62.66 t ha−1 under W1, W2 respectively. SOSC increased plant height, tomato (0–60 cm), while SO obtained ratio. Both SC consumption at seedling stage, blooming setting stage CC; harvest SC. Under overgrowth occurred resulting lower yield. difference between CC increasing stress. Overall, combination along 100%ETc (W1SOSC) more conducive promoting (73.40 ha−1) reducing , fertilizers 75%ETc (W2SOSC) potential achieving water-saving production arid semiarid regions.

Unreasonable irrigation and nitrogen application reduce tomato yield waste resources. This study explored the effects of water conservation reduction on yield, dry matter, quality, productivity use efficiency in Northeast China. Experiments were conducted during 2020 2021 at three levels (85–95 %, 75–85 65–75 % θFC) (120, 180, 240 kg hm−2). The optimal supply patterns obtained by establishing a newly evaluated Entropy Weight Method−Technique for Order Preference Similarity to Ideal Solution−Adversarial Interpretive Structure Model (EWM−TOPSIS−AISM). results showed that amount significantly affected quality (P ≤ 0.5). Proper deficit improved quality. Reducing rate but decreased yield. Increasing increased efficiency. Tomato was negatively correlated with (R= −0.25 R= −0.37 2021) −0.30 −0.20 2021). evaluation best mode our experiment θFC 180 hm−2. could promote sustainable production greenhouse tomatoes

Rhizobacteria from ‘flowering desert’ events contribute to the mitigation of water scarcity stress during tomato seedling germination and growth

Scientific Reports, Год журнала: 2021, Номер 11(1)

Abstract Tomato ( Solanum lycopersicum L.) is an important vegetable cultivated around the world. Under field conditions, tomato can be negatively affected by water scarcity in arid and semiarid regions. The application of native plant growth-promoting rhizobacteria (PGPR) isolated from environments has been proposed as inoculant to mitigate abiotic stresses plants. In this study, we evaluated Cistanthe longiscapa syn Calandrinia litoralis ), a representative flowering desert (FD) events (Atacama Desert, Chile), determine their ability reduce stress on seedlings. bacterial strains were characterized with respect PGPR traits, including P solubilization, 1-aminocyclopropane-1-carboxylate deaminase activity, tryptophan-induced auxin exopolysaccharide production. Three consortia formulated Bacillus then applied seeds, then, seedlings exposed different levels limitations. general, seeds inoculated presented significantly ≤ 0.05) greater growth (48 60 cm height 171 214 g weight) recovery rates (88 100%) compared those without inoculation (37 51 height; 146 197 fresh weight; 54 92% recovery) after exposure lack irrigation over time intervals (24, 72 120 h) before transplantation. Our results revealed effectiveness FD improve performance subjected scarcity; thus, use these represent alternative approach for farmers facing drought associated climate change regions worldwide.

Do agronomic approaches aligned to regenerative agriculture improve the micronutrient concentrations of edible portions of crops? A scoping review of evidence

Frontiers in Nutrition, Год журнала: 2023, Номер 10

Regenerative Agriculture (RA) is used to describe nature-based agronomic approaches that aim build soil health and crop resilience, minimize negative environmental outcomes, improve farmer livelihoods. A benefit increasingly attributed crops grown under RA practices improved nutritional content. However, we do not know the extent which influences quality what management context, can such effects be realized. scoping review of recent literature (Web Science, 2000–2021) was carried out assess evidence micronutrient quality. Papers included combinations could defined as Regenerative: “Organic Inputs” including composts manures, cover crops, rotations, residues biochars; “Reduced Tillage”, “Intercropping”, “Biostimulants” e.g. arbuscular mycorrhizal fungi; plant growth promoting bacteria, “Irrigation”, typically deficit-irrigation alternate wetting drying. The types reviewed were predetermined covering common sources food included: Tomato ( Solanum lycopersicum L. ), Wheat Triticum aestivum Rice Oryza sativa Maize Zea mays Pulses (Fabaceae), Alliums Allium spp. “other” (30 types). This supports a potential role for in increasing concentrations micronutrients edible portions several specific practices, although this context specific. For example, rice increased organic inputs showed significant increases grain zinc (Zn) concentration 15 16 studies. vitamin C tomato fruit ~50% studies when plants inputs, 76% deficit irrigation. Overall, magnitude reproducibility on most profiles difficult due diversity approaches, geographical conditions, limited number each these categories. Future research with appropriate designs, on-farm surveillance diagnostics are needed better understanding improving food, human nutrition, health.
