Dracaena Sanderiana

We evaluated two osmotic adjustment substances (glycine betaine (GB) and glycine (G) and a combination of both glycine + glycine betaine (G + GB) using two modes of application; irrigation and foliar sprays with Dracaena sanderiana plants. The plants were grown in containers and subjected to two levels of NaCl concentrations (2.0 and 7.5 dS m−1) over 8 weeks. Growth, pigment concentrations, and physiological parameters were assessed at the end of the trial. The foliar application of GB resulted in most optimal plant growth and biomass production in the presence of NaCl. The chlorophyll and carotenoid concentrations showed different trends depending on the osmotic adjustment substance applied and the mode of application. Stomatal density and dimensions varied considerably with respect to the osmotic adjustment substance supplied. The concentration of soluble sugars in leaves did not show a clear trend under the different treatments assessed. The exogenous application of G resulted in the highest concentration of free proline and proteins in leaves. The antioxidant capacity in leaves increased with both osmotic adjustment substances, and both means of application, under low and high saline conditions. We concluded that the foliar application of GB can be recommended in order to achieve cost-effective growth of D. sanderiana under saline conditions.

Among the various technologies that boost the production of crop, nutrient management has got an important impact in maximizing the yield. Application of balanced fertilizers alone is not only the solution for this problem, application of residue free nutrients that protects the soil health and environment is very important. Here comes the concept of organic farming. Hence, a field experiment was conducted in the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar to study the effect of organic nutrients on growth and physiological parameters of radish. The experiment was conducted with eighteen treatments in three replications and laid out in FRBD design. The treatment includes various sources of organic manures viz., FYM, vermicompost, enriched manure along with and without use of consortium biofertilizer. Biostimulants viz., buttermilk solution and EMI were given as foliar spray at 15 days interval as 2 sprays. The intercultural operations and plant protection measures were carried out as per the recommendation. The results of the experiment revealed that application of farm yard manure @ 25 t ha-1 along with consortium biofertilizer @ 2 Kg ha-1 and EMI @ 1:1000 dilution ha-1 as foliar application recorded the highest growth parameters viz., shoot length, number of leaves and shoot weight. The physiological parameters viz., leaf area and chlorophyll content were recorded the highest in the same treatment T6.

Alpinia zerumbet is an important medicinal and ornamental plant species. Drought stress is a major concern for sustainable horticulture crop production under changing climate scenarios. Trehalose (Tre) and 5-aminolevulinic acid (ALA) are osmoprotectants that play important roles in mitigating plant stresses. In this study, the effects of foliar application of 25 mM Tre or 10 mg L−1 ALA on biochemical and physiological parameters of A. zerumbet seedlings and their growth were evaluated under well-watered and drought-stressed (65% of field capacity) conditions. Drought caused reductions in physiological parameters and plant growth. These decreases were accompanied by increases in leaf free proline and glycine betaine concentrations and peroxidase activities. Foliar application of Tre or ALA remediated physiological and biochemical parameters and plant growth. Overall, foliar application of ALA or Tre proved to be beneficial for mitigating drought stress in A. zerumbet.

Soil Application

Conducting a field study to investigate the effects of foliar and soil fertilization with copper on the nutritional and physiological parameters and grain yield of common bean. The experimental design was a randomized block, in a 2 x 5 factorial scheme. The first factor was the site of application of copper fertilization. The second factor was copper doses: 0, 1, 2, 3, and 4 kg ha-1 (6 replicates). The following were evaluated: leaf nitrogen and copper contents, relative chlorophyll index (RCI), gas exchange, photochemical efficiency of photosystem II, and grain yield. The data were subjected to analysis of variance and F test (p-value < 0.05), using the Scott & Knott for qualitative data and polynomial regression for quantitative data. Leaf Cu content was higher with soil application (4% and 28%), both at 24 and 45 DAE, respectively. Net photosynthesis reached a maximum index of 18.77 µmol m-2 s-1 with foliar Cu fertilization at the dose of 4 kg ha-1. The application of 2.0 kg ha-1 Cu was the one that led to the highest grain yields; however, soil application stood out with a yield about 12% higher of the foliar. Soil fertilization proved to be more efficient in terms of Cu absorption and RCI rates, improving grain yield (12%) in relation to foliar, especially at the dose of 2 kg ha-1. The dose of 2 kg Cu ha-1 provided the best differential profit, reaching US$ 581.96 ha-1 and US$ 503.01 ha-1 for soil and foliar application, respectively.

Today, industries are increasingly concerned about the disposal of their waste. One of the proposed solutions to deal with certain wastes is through agriculture in the form of fertilizers. Thus, the objective of this study was to evaluate the effect of liquid tannery sludge as foliar fertilizer on the growth and physiology of passion fruit seedlings. The experiment was conducted in a greenhouse, in a randomized block design with six replications. Six treatments were applied to leaves: tannery sludge diluted in water (132, 263, 395 and 527 mL L-1); only water (control); and the conventional treatment. The following growth characteristics were evaluated: leaf production, plant height, crown diameter, stem diameter, total fresh matter and dry matter of the plants. The physiological characteristics evaluated were the indices chlorophyll, nitrogen balance, flavonoids, anthocyanins, and plant color. The flavonoid index increased in plants that received foliar application of 527 mL L-1 without compromising the other characteristics evaluated. The doses 263, 395 and 527 mL L-1 showed the best results for the growth characteristics, equaling those of the conventional treatments. Foliar application of tannery sludge can be recommended for yellow passion fruit seedlings.
