Application Methods

This study aimed to investigate the effects of different humic acid application methods (control, soil, foliar and soil + foliar) on chlorophyll content, dry matter weight of shoots and roots, concentrations of potassium (K), calcium (Ca) and sodium (Na), and K/Na and Ca/Na ratios of bean plants exposed to increasing salinity levels (0, 50, 100 and 150 mM). The effects of salt damage on shoots and roots of bean plants were significantly differed in humic acid application methods. Chlorophyll content decreased with the increase in salt doses at control and soil application of humic acid, while the decrease in chlorophyll content was lower in foliar application of humic acid. Shoot dry weight was not affected by humic acid applications, while root dry weight increased in soil + foliar application method. Soil + foliar humic acid application caused the highest shoot and root Na concentrations. Shoot Ca (2.61%) concentration in soil + foliar application was significantly higher compared to the other treatments, while the highest Ca concentration in roots (1.55%) was recorded in soil humic acid application method. The highest K concentration in roots was obtained in the control treatment (2.50%) followed by soil + foliar humic acid application (2.48%). The ratios of K/Na and Ca/Na in shoots decreased with the increase in salt application rates. The highest shoot K/Na (1456.1%) and Ca/Na (1274.1%) ratio in humic acid x salt interactions was found in soil application of humic acid without salt treatment. The root and shoot dry matter yield and K and Ca concentrations of the plants indicated that soil+foliar application method has a preventive effect for the plants against the 50 mM salt damage. The results showed that soil+foliar humic acid application in addition to the mineral fertilization required for beans can contribute to the growth and mineral nutrition of the plants under moderate salt stress (50 mM NaCl).

Nitrogen and micronutrients have a key role in many citrus plant enzyme reactions. Although enough micronutrients may be present in the soil, deficiency can develop due to soil depletion or the formation of insoluble compounds. The objectives of this study were to (1) determine the adsorption, distribution, and availability of Zn in a sandy soil; (2) compare the effectiveness of foliar and soil application methods of Zn on Huanglongbing [HLB] affected trees; (3) compare foliar application rates of Zn for HLB-affected trees; (4) determine the effect of N rates on yield, soil inorganic N distribution patterns, and tree growth parameters. Tree rows were supplied with three N rates of 168, 224 and 280 kg·N·ha−1 and Zn at single and double recommended rates (recommended rate = 5.6 kg·Zn·ha−1) using foliar and soil application methods, in a split-plot experimental design. The results show that Zn concentration in the 0–15 cm soil depth was three times higher than the 30–45 and 45–60 cm soil depths during the study. An adsorption study revealed high Zn (KD = 6.5) sorption coefficients at 0–15 cm soil depth, while 30–45 and 45–60 cm depths showed little sorption. Leaf Zn concentration for foliar spray was two times higher than the soil application method. A nitrogen level of 224 kg N ha−1 improved canopy volume when compared to other N levels at the expense of reduced fruit weight. Foliar Zn application at 5.6 or 11.2 kg ha−1 and N rate at 224 kg ha−1 appear to be adequate for improving the performance of HLB-affected citrus trees.

A field experiment was conducted during rabi season of 2015-2016 at Navsari Agricultural University, Navsari to study the impact of cobalt application methods on chickpea yield, nutrient content and soil status. Four cobalt application methods with three levels of each were evaluated with one absolute control and one with seed priming of water were evaluated with randomized block design with three replications. Least level of seed treatment, soil application and foliar application of cobalt gave highest chickpea seed yield and decreased there after. As cobalt levels increased, NPK content and uptake are decreased linearly in all the methods except seed priming method, however cobalt content and uptake increased linearly by seed treatment and foliar application, on the contrary it decreased linearly by seed priming and soil application of cobalt. Soil application of cobalt at 50 g ha-1 recorded highest chickpea seed yield, residual NPK and Co and which can be useful for succeeding crop and this can be recommended from the cobalt nutrition point of view in plants and animals followed by seed priming at 1 ppm.

Abstract Background The diamondback moth (Plutella xylostella L.) (Lepidoptera: Plutellidae) is one of the major pests in cabbage which causes severe loss to the cruciferous crops. Entomopathogenic fungi Beauveria bassiana and Metarhizium anisopliae have been established as endophytes in cabbage plants by seed treatment/root inoculation/foliar application methods in glasshouse conditions. Main body A glasshouse experiment was conducted to study the effect of endophytic isolates of B. bassiana (NBAIR Bb-5a and NBAIR Bb-45) and M. anisopliae (NBAIR Ma-4 and NBAIR Ma-35) on P. xylostella in cabbage using detached leaf bioassay method. The isolates were applied through seed treatment/root inoculation/foliar application at the concentration of 1 × 108 spores/ml and evaluated at 15, 30, 45, and 60 days after treatment (DAT) in 2017 and 2018. These isolates were colonized in cabbage leaf tissues from 15 to 60 DAT. All 4 isolates showed different mortality percentages during 15–30 DAT, and no mortality was observed after 45 and 60 DAT in different inoculation methods during both years. Among the application methods tested, foliar application method gave the highest mortality of 70–80% at 15 DAT and 12–58% at 30 DAT mortality of 2nd instar larvae of P. xylostella in cabbage. Among the isolates tested, NBAIR Ma-35 showed the highest mortality (35–79%) in all the 3 inoculation methods tested. Conclusion Endophytic isolates of B. bassiana and M. anisopliae suppressed the population of P. xylostella on cabbage leaves in three inoculation methods tested. Among all the methods tested, foliar application method showed highest mortality. These promising isolates have to be further tested under field conditions for management of P. xylostella in cabbage.

The Impact

The objective of this study was to assess the yield efficiency of sulphur-enhanced fertilisers, depending on the dose and application method, in a short-lived (three-year) monoculture of winter oilseed rape under the climate and soil conditions of south-eastern Poland. The experiment was carried out between 2010 and 2013 on winter oilseed rape (Brassica napus L. var. napus) of the Orlando variety, fertilised with different sulphur doses—0, 20, 40 or 60 kg S ha−1 applied in different method—soil application sowing, foliar application in the spring, and soil application sowing + foliar application in the spring (combined application). Following the harvest, seed and straw yields and the content of macroelements (N, S, P, K, Ca and Mg) in the seed and straw samples were determined. The harvest indices were also established for each of these elements. The impact of sulphur on winter oilseed rape yield depended significantly on both the dose and the application method. Even at the lowest dose (20 kg·ha−1), sulphur materially increased seed yield, regardless of the application method. With autumn soil application and foliar application, differences between the lowest dose and the higher doses (40 and 60 kg·ha−1) were not significant. However, with combined application, the highest dose (60 kg·ha−1) significantly increased yield compared to the lower doses. In general, all the fertilisation approaches significantly increased the N, P, K, Ca and Mg contents compared to the control sample, but the differences between them were not substantial. Each of the sulphur application approaches decreased the harvest index for sulphur. The foliar application of each of the doses decreased the harvest indices for N, P, K and Ca. The soil application of 20 kg·ha−1, and the mixed application of 40 and 60 kg·ha−1, all increased the harvest indices for P, K and Ca.

Physiological And Biochemical

Peppermint (Menthapiperita L.) is aneconomically important medicinal and aromatic plant grown in different areas worldwide. Secondary metabolites were fundamentally produced by genetic processing;however, environmental factors affect their biosynthesis. Salinity is the most important abiotic stress which induces morphological, physiological, and biochemical changes in plants.To investigate the influence of salinity stress (0, 25, 50, 75, 100 and 125 mMNaCl)on chlorophyll content, stomatal conductance, relative water content (RWC), proline, Na+ and K+ content, antioxidant enzymes of catalase (CAT), peroxidase (POX) and polyphenol oxidase (PPO), protein, essential oil yield and dry weight of peppermint, a greenhouse study was conducted. The results indicated that salinity had a significant effect on foregoing parameters. Changes in chlorophyll content werepeak and stomata conductivity was a single function. Based on estimations, the highest chlorophyll contentwas recorded for low salinity (60 mMNaCl).The plant proline content was higher in stress condition compared tocontrol plants. The highest proline content observed in 125mM NaClconcentration was two times higher than that of control plants.There was an increase and then decrease in CAT and POX activities, respectively, in lower and sever levels of salinity.A single equation was the best-fit equation for changing PPO enzyme activity under stress conditions.The dry matter has been affected dramatically by salinity and decreased from 11.34g under the non-stress condition to 4.24 g under high stress condition. Essential oil percentage (in dry matter) increased in moderate salinity stress. We found that the amount of essential oil per plant was linearly decreased. So, the highest (9.78 g plant-1) amount of essential oil per plant belonged to control group and the lowest (4.6 g plant-1) wasobserved for full stress condition.

A field experiment was conducted during rabi season of 2015-2016 at Navsari Agricultural University, Navsari to identify suitable cobalt application method and optimum level for enhancing chickpea yield. There were four cobalt application methods and three levels of cobalt each i.e. seed priming at 0.5, 1.0 and 1.5 ppm, seed treatment at 1, 2 and 3 g kg-1 seed, soil application at 50, 100 and 150 g ha-1, foliar application at 0.01, 0.025 and 0.05% and one control with water priming and one without seed treatment were evaluated in randomized block design with three replications. In general least level of all methods has recorded highest growth and yield of chickpea. As cobalt levels increased, growth and yield of chickpea was decreased linearly in all methods. Soil application of 50 g CoCl2 ha-1 produced highest seed yield hence this treatment can be recommended for higher seed yield and can be useful for succeeding crop.

Following soil and foliar treatments with zinc and boron, concentrations of leaf microelements were measured in mango trees (Mangifera indica L. cv. Kensington Pride) in order to determine the best method of application. Quarterly foliar application of zinc sulphate (1.0%) was the most cost-effective way to maintain leaf zinc above the critical concentration of 20 mg/kg dry matter. Yearly soil application of 50 g of Solubor per tree maintained leaf boron above the adequate concentration of 50 mg/kg. Single Solubor soil applications of 100 and 200 g/tree.year were phytotoxic to mango trees, with severe leaf burn associated with leaf boron concentrations of 320 mg/kg. In general, mango yield was not significantly (P>0.05) affected by any of the treatments, nor was it significantly (P>0.05) correlated with zinc or boron leaf concentrations.
