N Rates

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.

Application Methods

Zinc and boron are the most important trace nutrients for crop production. In recent years, cultivable lands in Bangladesh suffer deficiency of these elements. This research aimed to find out a suitable and effective application method to improve the overall soil nutrient up-gradation for crop production. Here, the treatments were control (T0), soil application of zinc (T1), soil application of boron (T2), foliar application of zinc (T3), foliar application of boron (T4), soil application of zinc and boron (T5), soil application of zinc with foliar application of boron (T6), soil application of boron with foliar application of zinc (T7), and foliar application of zinc and boron (T8). The source of zinc @ 3 kg ha-1 and boron @ 2 kg ha-1 as a basal dose were zinc sulphate and borax, respectively. The foliar application of zinc and boron was done at 45 and 60 days after transplanting @ 1% and the source were chelated zinc and solubor boron, respectively. The result of the experiment was concerning the highest plant height, plant spreading, the number of leaves, stem length, stem diameter, fresh weight of loose leaves, head diameter, head thickness, dry matter content of head, and yield. The highest yield of cabbage was found with the treatment foliar application of zinc and boron (T8). The results of this investigation revealed that the application methods of zinc and boron positively affect the growth and yield of cabbage whereas foliar application of these nutrients always makes higher growth parameters with yield.

The Impact

Aim: To determine the impact of soil and foliar application of ZnSO4.7H2O at late stages of wheat as heading initiation (5% ear formation), 100% heading (complete ear formation) and heading initiation and 100% heading along with recommended dose of fertilizer on growth, yield and quality of zero till wheat. Methodology: The field experiment was conducted on zero till wheat. The treatments consisted of control (no Zn), soil application of 12.5, 25, 37.5, 50 kg ha-1 ZnSO4.7H2O and foliar application of 0.5% Zn as one spray at heading initiation (5% ear formation), one spray at 100% heading (complete ear formation) and two sprays at heading initiation and 100% heading with recommended dose of fertilizer. These treatments were evaluated in RBD with three replications. Results: Soil application of 50, 37.5 and 25 kg Zn ha-1 with two foliar sprays of 0.5% at heading initiation (5% ear formation) and 100% heading (complete ear formation) stages gave significantly higher average grain and straw yield and Zn concentration in grain than other treatments, including control. Interpretation: Enhanced application of Zn as soil and foliar application ameliorates soil Zn deficiency and increases protein content in grains, which might influence the quality and yield of zero tilled wheat. Key words: Foliar spray, Grain yield, Wheat, Zinc

A field experiment was carried out during rabi season of 2018-2019, at college farm, College of Horticulture, Dr. Y.S.R. Horticultural University, Venkataramannagudem, West Godavari District, Andhra Pradesh. The experiment was laidout in a Randomised Block Design with eleven treatments (viz., T1- NAA @ 50 ppm, T2-NAA @ 100 ppm, T3-GA3 @ 50 ppm,  T4-GA3 @ 100 ppm, T5-Thiourea @ 250 ppm, T6-Thiourea @ 500 ppm, T7-28-Homobrassinolide @ 0.1 ppm, T8-28-Homobrassinolide @ 0.2 ppm, T9-Triacontinol @ 2.5 ppm, T10-Triacontinol @ 5 ppm, T11-(Control) Water spray) and three replications. The treatments were imposed at 30 and 45 DAT in the form of foliar spray. Foliar application of GA3@ 100 ppm (T4) had recorded the maximum plant height (108.20 cm), leaf area (9.53 cm2) and leaf area index (0.74). Foliar application of thiourea @ 250 ppm (T5) had recorded the maximum values with respect to number of primary branches (15.03 plant-1), number of secondary branches (83.40 plant-1), plant spread (1793 cm2 plant-1), fresh weight (376.29 g plant-1), dry weight (103.54 g plant-1) and number of leaves plant-1((298.8). The same treatment (T5) had recorded the highest values with respect to crop growth rate (1.44 gm-2d-1), chlorophyll-a (1.40 mg g-1), chlorophyll-b (0.076 mg g-1) and total chlorophyll contents (1.48 mg g-1) in the leaves.

The aim of the study was to compare soil and foliar application of Si to relieve stress in wheat caused by excess Zn in the soil. Two pot experiments were carried out in which the soil was contaminated with zinc sulphate at the dose of 600 mg kg−1 Zn before sowing. Si was applied in the soil in the following doses 200 mg kg−1 and 400 mg kg−1 Si and as foliar spraying in concentrations 2 mM L−1 and 6 mM L−1 Si in the form of sodium silicate. The applied dose of Zn was toxic to wheat and caused a significant decrease in the biomass of shoots and roots. Soil application of Si reduced the negative effect of Zn on plants and significantly increased the biomass of the tested organs. The foliar application of Si did not reduce the decrease of plant biomass. Soil contamination with Zn caused a drastic increase in Zn concentration in shoots and roots, while Si applied in the soil significantly decreased this concentration. The increase in soil pH, which was caused by sodium silicate, also affected the decrease in Zn concentration in plants. The plants absorbed Si applied to the soil, which is indicated by an increase in the Si content in shoots compared to the control. In the case of foliar spraying, only a higher dose of Si increased its concentration in the plants. The application of Si in the soil, in contrast to foliar application, reduced the transfer of Zn from roots to shoots. The higher effectiveness of soil application of Si than foliar application in alleviating the toxicity of Zn was associated with both an increase in pH and a higher uptake of Si by plants.

Wheat (Triticum aestivum L.) is one of the main foods globally. Nutrition problems associated with Zinc and Iron deficiency affect more than two billion individuals. Biofortification is a strategy believed to be sustainable, economical and easily implemented. This study evaluated the effect of combined Zn and Fe applied as foliar fertilizer to winter wheat on grain yield, quality, Zn and Fe concentration in the grains. Results showed that treatments containing high Fe increased the yield. Grain crude fat content remained unaffected. Crude fiber was enhanced up to three-fold by 60% Zn + 40% Fe5.5 (5.5 kg ha−1 of 60% Zn + 40% Fe). Moreover, 80% Zn + 20% Fe5.5 (5.5 kg ha−1 of 80% Zn + 20% Fe) was the best combination for increasing crude protein. Zinc applied alone enhanced Zn concentration in grain. In addition, Fe was slightly improved by an application of Zn and Fe in the first year, but a greater increase was observed in the second year, where 100% Fe13 (13 kg ha−1 of 100% Fe) was the best in improving Fe in grain. Foliar application of Zn and Fe is a practical approach to increase Zn and Fe concentration, and to improve the quality of wheat grains.

The field demonstrations were carried out during 2016-17 in Rabi season to know effect of zinc and boron on yield of brinjal at total 10 farmers from Bharuch district. The production of brinjal is quite low in some part of the district due poor soil fertility status and imbalance fertilizer application by farmer. There was complete absence of micronutrients application to the crop. The initial soil analysis data showed deficiency of zinc and boron in experimental soil. Thus, to compare effect and method of use of zinc and boron; soil application and foliar spray were made along with improved practices against farmer practices. The highest plant height, average fruit weight, number of fruits per plant and fruit yield of brinjal was recorded with the soil application of zinc and boron which was superior over the foliar spray and farmer’s practices. The gross return, net return and benefit cost ratio recorded was also maximum in improved practices consisting soil application of zinc and boron as compared farmer’s practices.

Foliar Application seems to be an upcoming and ongoing research area especially in the field of agriculture. This is been in practice in various parts of the world and proved its positive results in its field [1,2]. Foliar application can be explained as spraying the suitable fertilizer solution (condition is, that it should be water soluble) on the surface of the leaves of growing plants [3]. This practice not only saves quantity of fertilizer used but also improves the uptake of a particular micronutrient by the crops and boosts the yield too. Interaction between crop’s genetic potential and the environment in which it grows is detrimental for the yield of a crop [4]. Soil application of nitrogen is a conventional method to supply nitrogen to plants and for improvement in any field adhering to the old ways will not be a better option [4]. In some instances, the availability of urea becomes inadequate for the farmers at sowing time. In such situation the foliar application of plant nutrient is effective and economical for some crops [5]. It has been shown in some studies that uptake of micronutrients directly from plants is more rapid and quicker for better results in yields than soil application[1]. As mentioned above, that the fertilizer should be water soluble for foliar spray and moreover, it should also be noted that the particular crop plant also should be suitable for aerial spray. The best results of foliar application also depends on the soil condition as if soil conditions are unfavourable when micronutrients are needed, it may be desirable to make foliar applications of the plant nutrients

Lowbush blueberries (Vaccinium angustifolium Ait.) in two commercial fields were treated with a preemergent soil application of ZnSO4 at 0.34 g Zn/m2 or a prune-year or crop-year foliar application of Zintrac (1.76 g Zn/L) in a RCB design with five treatments and nine blocks, using 1.5 x 15-m treatment plots. Prune-year foliar Zintrac treatments were applied 20 June and 30 June at 53.8 mL·m-2 or 20 June at 107.6 mL·m-2. A crop-year application of Zintrac at 53.8 mL·m-2 was made on 26 June at only one location. Composite leaf tissue samples taken 14 July of the prune year indicated that two applications of Zintrac at 53.8 mL·m-2 raised Zn concentrations at both locations more than a single application at twice the rate. Soil application of ZnSO4 did not raise leaf Zn concentrations compared to the control at either location. Crop-year leaf samples taken 6 July at the site that received the crop-year foliar treatment indicated no carryover effect of prune-year Zn treatments on leaf Zn concentration, but crop-year foliar application of Zn from Zintrac did raise leaf Zn concentrations compared to the controls. The characteristics of stems sampled in the fall of the prune year at each location (stem density, stem length, flower bud formation) were not meaningfully affected by any of the prune-year treatments. Blueberry yield was not affected by any of the treatments at either location. These data suggest that control plot leaf Zn concentrations of about 15 ppm in both fields were adequate. Raising the leaf Zn concentrations to about 80 ppm with two applications of Zintrac at 53.8 mL·m -2 had no effect on growth or yield.

Effects of foliar applied macro (NPK) and micro nutrients (Fe, Mn, Zn, Cu and B) at different time on yield, quality and benefit: cost ratio of rainy and winter season guava were evaluated in north western Haryana, India. The two season’s data depicted that physico- chemical characters with respect to fruit set, fruit retention, fruit size, average fruit weight and yield were significantly increased with foliar application of macro and micro nutrients at vegetative, flowering and fruiting stage (T7). The shoot C: N ratio was also found highest with T7 foliar treatment which was followed by T5 in both the seasons. The T7 foliar spray resulted in maximum benefit: cost ratio in both the seasons. Proper fertilization strategies can help fruit growers to get good yield and quality fruits. Bangladesh J. Bot. 50(4): 1159-1164, 2021 (December)
