The results of the analysis of variance at the probability level of 0.01 showed that the effect of genotype in terms of all traits except for the traits of days until tassel dries, peduncle outside the ag leaf, tassel length, the number of ll seeds and the depth of the seeds are signi cantly different. Based on the mean comparison done by Duncan's method, G3, G6, G7 and G4 genotypes were identi ed as favorable hybrids and G17, G20, G19 and G18 hybrids were identi ed as unfavorable hybrids in terms of all evaluated traits. Based on the graphic analysis done on the data, the genotypes G5, G4, G6, G3, G9 and G14 can be identi ed as desirable hybrids. Also, based on the genotypes grouping diagram, the hybrids were grouped into 9 groups in terms of traits. The correlation diagram between the traits also indicated that the grain yield trait has a positive correlation with tassel length, leaf length, leaf width, and leaf surface traits. Based on the principal components analysis, the traits were named into 10 components, which are respectively: components of ear characteristics, time characteristics in terms of maturity, leaf characteristics, Characteristics of maize plant 1, characteristics of maize plant 2, physiological characteristics and germination, the crown part of the ear characteristics, grain characteristics, grain yield and characteristics of the ear head.

However, the synergistic effect of PA and fertilizer has not been thoroughly studied. In this study, we assessed the biostimulatory effect of different rates of foliar PA application (i.e., 0, 0.25, 0.5, 1, and 2% PA/ddH 2 O (v/v)) combined with full rate (i.e., 0.63, 0.28, 1.03 g) and half rate of nitrogen-phosphorus-potassium (NPK) fertilizer on the yield and nutritional quality of greenhouse-grown tomato (Solanum lycopersicum 'Scotia'). Plants treated with 0.25% and 0.5% PA showed a significantly (p < 0.001) higher maximum quantum efficiency of photosystem II (Fv/Fm) and increased potential photosynthetic capacity (Fv/Fo), especially when combined with the full NPK rate. Leaf chlorophyll was significantly (p < 0.001) increased by approximately 0.60 and 0.49 folds in plants treated with 2% PA and full NPK rate compared to no spray and water, respectively. Total number of fruits was significantly (p < 0.001) increased by approximately 0.56 folds with the 2% PA irrespective of the NPK rate. The combined 2% PA and full NPK rate enhanced total fruit weight and the number of marketable fruits. Similarly, fruit protein, sugar and 2,2-diphenyl-1-picrylhydrazyl (DPPH) activity were significantly (p < 0.001) enhanced by the combined 2% PA and full NPK rate. In contrast, the 0.5% PA combined with half NPK rate increased fruit carotenoid and phenolic contents while the 2% PA plus half NPK rate enhanced fruit flavonoid content. Generally, the synergistic effect of PA and NPK fertilizer increased fruit elemental composition. These showed that foliar application of 2% PA with full NPK rate is the best treatment combination that can be adopted as a novel strategy to increase the productivity and quality of tomato fruits. However, further study is required to investigate the molecular basis of PA biostimulatory effect on plants. Tomato (Solanum lycopersicum) is the most cultivated greenhouse and consumed vegetable worldwide due to its diverse use in sauces, soups and puree 1. Its fruits are known as a potent source of health-enhancing phytochemicals including phenolics, flavonoids, polysaccharides, vitamins and carotenoids, which makes it a good model for studying fruit quality 2. These compounds are known to mitigate the destructive effects of reactive oxygen radicals produced during cellular oxidative stress. Dietary intake of tomato fruits has been reported to stimulate antioxidant effects and help prevent chronic diseases in humans including cancers, atherosclerosis, cardiovascular, neurodegenerative and inflammation disorders 2,3. Moreover, tomato productivity and phytochemical properties are highly dependent on growing medium fertility status, growing conditions and plant genetic characteristics 4. It has been reported that appropriate fertilization enhances soil fertility and promotes crop yield 4. Additionally, the high demand for horticultural crops

In order to improve food security in these areas, it is imperative to employ suitable irrigation management techniques and identify drought-tolerant cultivars. A 2-year field experiment (2019–2020) was conducted in a semi-arid region of Iran to assess the impact of different irrigation methods and water deficit stress on forage sorghum cultivars’ yield, quality, and irrigation water-use efficiency (IWUE). The experiment involved two irrigation methods, i.e., drip (DRIP) and furrow (FURW), and three irrigation regimes supplied 100% (I100), 75% (I75), and 50% (I50) of the soil moisture deficit. In addition, two forage sorghum cultivars (hybrid Speedfeed and open-pollinated cultivar Pegah) were evaluated. This study revealed that the highest dry matter yield (27.24 Mg ha−1) was obtained under I100 × DRIP, whereas the maximum relative feed value (98.63%) was achieved under I50 × FURW. Using DRIP ...

However, its practical application has been limited due to its low adsorption capacity and negative effects on plant growth. To address these issues, three pre-treatment methods (water washing, microbial aging, and freezing-thawing aging) were employed to further improve the physical structure and chemical properties of hydrochar. A seed germination test with kale (Brassica oleracea var. acephala D.C) was conducted to evaluate the phytotoxicity of modified hydrochars. The results showed that microbial aging considerably enhanced the physicochemical properties of the hydrochar. Specifically, under microbial aging, the bulk density of microbial-aged hydrochar (MHC) decreased by 8.1%, the porosity increased by 24.8%, and the water-holding capacity increased by 36.54% compared to fresh hydrochar (FHC). Moreover, the surfaces of MHC and freezing-thawing aged h...

However, maize stands are damaged quickly in the case of nutrient and water deficiency. This research was carried out under dripping irrigation conditions and control plots without irrigation, involving seven different maize hybrids. The obtained results showed no existing variation in the dry matter content of cob (DMC) between the irrigated and non-irrigated treatments. Correlation analysis showed that increasing DMC causes decreasing moisture content of cob (MC) of sweet maize with irrigated and non-irrigated treatments. DMC and MC are important factors in the yield index on irrigation treatments. Biplots showed that the Dessert R72 (10.82) hybrid had maximum yield and effect on Brix/Abbe and Brix/Atago Pal-1, while the Messenger hybrids (42.96) had maximum effect on MC. It was also shown that DMC and MC are important factors in the yield index on irrigation treatments on hybrids. ...

The identification of the main drivers affecting GHGs is crucial for planning sustainable agronomic practices and mitigating global warming potential. The main aim of this research was to evaluate the impact of environmental drivers (soil temperature and waterfilled pore space, WFPS) and crop residue rates on CO 2 , NO, and NO x fluxes under conventional tillage (CT) and no-tillage (NT) systems. The accuracy of Random Forest Regression (RFR), Multiple Adaptive Regression Splines (MARS), and General Linear Models (GLM) in predicting CO 2 , NO, and NO x fluxes were also assessed. In both CT and NT systems, CO 2 , NO, and NO x fluxes decreased with increasing WFPS. Increasing temperature resulted in higher CO 2 emissions and lower NO and NO x emissions. Higher residue rates resulted in significant increases in CO 2 emission, whereas the NO and NO x emissions increased by decreasing the ratio of residue. For CO 2 prediction, the RFR provided the largest R 2 with the observed data. For NO-N and NO x-N prediction, RFR was the most efficient algorithm, but NO-N can be predicted with better accuracy. The output of this research highlights the importance of agronomic practices for climate mitigation, along with the possibility of using RFR to predict GHGs fluxes.

The aim of this study was to test and valuate the effects of one zinc (Zn) and two amino acids-containing (AS) foliar fertilizers on a fodder corn hybrid’s physiological and biochemical processes. The experiment was conducted in field conditions. The following parameters of a fodder maize hybrid were measured one, two, three, four, five, and six weeks after the treatments (WAT): physiological (relative chlorophyll content and the effectiveness of PSII); biochemical (activities of superoxide dismutase (SOD); ascorbate peroxidase (APX) and guaiacol peroxidase (POD); the concentration of malondialdehyde (MDA); and proline. The yield increased by 10%, 6%, and 10% at Zn, Zn+AS1, and Zn+AS2 treatments. The yield parameters, such as grain/cob and ear weight, were also significantly higher under the applied three treatments relative to the control. The relative chlorophyll content was sign...

Three maize hybrids (Zea mays L.) of different maturity classes and length of vegetation period (FAO 400, FAO 490, and FAO 380) were selected and for trials during the 2019 growing season. Three different nitrogen (N) fertilization treatments (0, 120, and 305 kg·N·ha−1) were applied in order to assess variability in yield-related components. The effect of hybrids, fertilizer, and the interaction of the examined hybrids in relation to fertilizer was significant on yield and oil and protein content. Correlation and biplot analysis show that increases in the lipid peroxidation (LP) amount in the plant leaf stages cause a decrease in the oil content of the harvested yield. The activity of ascorbate peroxidase (APX) and LP at the six-leaf stage directly affects the protein content. The amount of APX at the silkin...

The study site was at the University of Debrecen’s Látókép Experiment Station in Hungary. The date of emergence of the tested maize hybrids was monitored under control (0 kg N ha−1), 120 kg ha−1 N + PK, and 300 kg ha−1 N + PK nutrient levels in a long-term field experiment. In 2020, maize hybrids (H1 = FAO 490; H2: FAO 420–440; H3 = FAO 420; H4 = 490; H5 = 320–340; H6 = FAO 350–370) growing under natural precipitation supply conditions without irrigation were included in the study. During the days of emergence, different moisture, protein, oil, starch, and yield production levels were observed, according to the variance analysis. In diverse maize hybrids, increasing or decreasing fertilizer treatment resulted in diverse productivity metrics. Regression analysis revealed that the day of emergence had a greater impact on protein,...

The experiment was performed on six maize hybrids in a randomized complete block design (RCBD) with three replications under regular irrigation and limited irrigation in the vegetative and reproductive stages in Iran. Drought tolerance indices (TOL, MP, GMP, STI, SSI, and HAR) for the grain yield of genotypes were calculated, and principal component analysis was based on them. The results obtained from estimating the indices showed that the SC647 and KSC704 hybrids, while having good performance in both conditions, also have drought tolerance. Examining the correlation between drought tolerance indices and yield in both conditions, among the indices used to detect drought tolerance, STI, MP, and GMP indices can be considered suitable for selecting high-yielding hybrids in these conditions. The principal components analysi...
