Plant nutrition is an important aspect that contributes significantly to sustainable agriculture, whereas minerals enrichment in edible source implies global human health; hence, both strategies need be bridged ensure "One Health" strategies. Abiotic stress-induced nutritional imbalance impairs plant growth. In this context, we discuss the molecular mechanisms related readjustment of nutrient pools for sustained growth under harsh conditions, and channeling (seeds) address future security. This review particularly highlights interventions on (i) physiological responses mineral nutrients crop plants stressful environments; (ii) deployment breeding biotechnological optimization acquisition, their transport, distribution changing environments. Furthermore, present also infers recent advancements biotechnology-based biofortification approaches enhancement optimize yield grain concentrations control stress-prone environments food

Scolymus hispanicus L. is a wild edible species with wide distribution in the Mediterranean area. Recent research has focused on domestication of greens, which essential for preservation agroecosystems and increase biodiversity, especially under adversely changing climate conditions. In present work, aim was to evaluate response S. plants different fertilization regimes that varied amounts nitrogen, phosphorus potassium regard plant growth chemical composition leaves. For this purpose, were grown pots within an unheated greenhouse. Seven experimental treatments used, including six fertigation (SH1-SH6) control treatment (SHC), where no fertilizers added. Fresh yield beneficially affected by included high content P K (e.g., SH3 SH5), while lesser these macronutrients SH1 SH4) resulted higher chlorophyll (SPAD index) leaf terms mineral profile, improved dietary fiber carbohydrates content, whereas untreated had highest ash, fat crude protein.

Effects of several superabsorbent polymers on soil exchangeable cations and crop growth

Environmental Technology & Innovation, Год журнала: 2023, Номер 30, С. 103126 - 103126

Owing to their excellent water absorption and retention properties, superabsorbent polymers have become an important technology for realizing agricultural savings. To explore the exchange pathways of exchangeable cations in soil caused by different effects on crop nutrient uptake growth, three types polymers, sodium acrylate, potassium acrylate acrylamide–sodium were used this project study dosages root morphology distributions Na+, K+, Ca2+ Mg2+ tips. The results as follows: among all treatments, inhibition effect polymer was most obvious. Compared with CK, biomass decreased 70.3% (AN2), length surface area 62.7% 61.1% respectively, plant K+ Na+ increased 18.5% 2423% 27.6% 18.7% respectively. Adsorption experiments further proved that adsorbed more than 95% while releasing into after swelling.

Seaweed extracts have shown profoundly positive effects on crop growth, quality and reproduction in diverse agricultural horticultural crops. can be used to promote the rooting growth of cuttings perennial fruit species like kiwifruit (Actinidia deliciosa). In this study, were treated with 1, 5, 10 50% solutions G Sap (Gracilaria edulis), K (Kappaphycus alvarezii), AN (Ascophyllum nodosum), EM (Ecklonia maxima), HA (Humic acid) control (water) for 6 h as base dipping. Subsequently, treatments Sap, AN, EM, repeated every 15 days a period six months application 50 ml potted cuttings. All exhibited significant percent all cultivars, namely 'Monty', 'Abott', 'Hayward', 'Allison' 'Bruno' (P ≤ 0.01) compared control. Shoot root parameters including leaf number per cutting, roots branches, plant height, shoot diameter, length, diameter weight positively increased seaweed 0.05). Cuttings extract significantly higher levels pigments (chlorophyll a, chlorophyll b total carotenoids), metabolites (total carbohydrates soluble phenols) less electrolyte leakage Significant negative correlations observed between biochemical combined nutrient concentration. Principal component analysis (PCA) revealed that PC1 PC2 (first two principal components) accounted 75% entire variation.

Most of Camellia oleifera forests have low fruit yield and poor oil quality that are largely associated with soil fertility. Soil physical chemical properties interact each other affecting fertility C. growing under different conditions produced composition. Three main types were studied, redundancy, correlation, double-screening stepwise regression analysis used for exploring the relationships between nutrients uptake properties, shedding light on transport law nutrient elements from root, leaves, kernel, regulation composition.In present study, available content forest mainly regulated by water content, pH value, total N, P Fe contents. Seven (N, P, K, Mg, Cu, Mn C) key kernel's growth development, Cu contents determining 74.0% traits. The characteristics these leaves to kernel had synergistic antagonistic effects. Increasing production unsaturated fatty acid can be accomplished in two ways: one through increasing Zn applying corresponding foliar fertilizers, while maintaining proper moisture fertilizer surface layer Mg Ca deep gully.Soil type controlled absorption pH, content.

Abstract Growth and productivity of plants primarily depend on the balanced distribution carbon (C) nitrogen (N) among different organs. Previous studies crop improvement have focussed C or N assimilation distribution. However, recent findings reveal that form a complex integrated network are often dependent each other to affect productivity. The underlying physiological molecular mechanisms involved in coordinated plant organs yet be fully uncovered. Crucial roles regulating balance played by transporters mediate their movement across In Cotton, which has an indeterminate growth pattern, source–sink assimilate could major bottleneck impeding fibre This review summarises our current understanding transport mechanisms, explores compares approaches C–N cascade, including cotton species.

Magnesium is an essential macronutrient for plant photosynthesis, and in response to Mg deficiency, dicots appear more sensitive than monocots. Under we investigated the causes of differing photosynthetic sensitivities a dicot monocot species. Rice (Oryza sativa L.) cucumber (Cucumis sativus were grown hydroponic culture explore their physiological responses deficiency stress. Both Mg-deficient rice plants exhibited lower biomass, leaf area, concentration, chlorophyll content (Chl) compared with Mg-sufficient plants. However, marked decline Chl carotenoid (Car) occurred cucumber. A CO2 concentration chloroplasts (Cc) was accompanied by decrease maximum rate electron transport (Jmax) ribulose 1,5-bisphosphate carboxylation (Vcmax), restricting utilization photorespiration (Pr) increased under deficiency. Additionally, cucumber, Car non-photochemical quenching (NPQ) reduced supply. Meanwhile, significantly fraction absorbed light energy dissipated additional mechanism (Φf,D). suppressed photosynthesis attributed comprehensive restrictions mesophyll conductance (gm), Jmax, Vcmax. Cucumber due NPQ, higher rates alternative pathways, subsequently, photooxidation damage.

First things first: Widespread nutrient deficiencies limit yields in smallholder oil palm fields

Agricultural Systems, Год журнала: 2023, Номер 210, С. 103709 - 103709

Опубликована: Июнь 28, 2023

Indonesia is the most important oil palm producing country. Nearly 40% of planted area managed by smallholders, with yields well below potential. Efforts to increase productivity have focused on source planting material, little attention paid plant nutrition. To assess degree which current in smallholder fields limited nutrients scenarios distinct sources material. We collected detailed data leaf nutrient concentration from 30 derive minimum sampling size needed diagnose status. Subsequently, we yield and type 973 importance status material determination yield. Potassium (K) deficiency was widespread (88% fields) often severe. two thirds were also deficient for nitrogen (N) boron (B), half phosphorous (P) deficient, one third magnesium (Mg) deficient. Nutrient imbalances, especially between K N, common. Fields sufficient P, levels yielded 47% more (equivalent 1.2 t ha−1) than across entire range materials. conclude that improved nutrition increases fresh fruit irrespective The advantage certified reflected higher extraction rates. Increased existing plantations through offers opportunity improve profits livelihoods, whilst at same time increasing total production without bringing new areas into cultivation.
