1、Fertilization and rotation enhance tobacco yield by regulating soil

Fertilization enhanced yield mainly by altering pH and available nutrient content. Among microbial attributes, module hubs most strongly promoted tobacco yield. Soil microbiome network structure is highly related to nutrient cycling and crop growth in agroecosystems.

2、Effects of fertilization methods and film removal periods on soil

We analyzed differences in soil nutrients, microbial community composition, and tobacco growth under different treatments. The results showed that, compared with other treatments, the combination of hole fertilization and T2 significantly promoted tobacco growth.

3、Yield increasing foliar fertilizer for tobacco and preparation method

With the adoption of the foliar fertilizer, tobacco yield can be increased effectively, tobacco growth is promoted by plant growthhormone while tobacco quality cannot be affected, weed growth can be inhibited to a certain extent, and the foliar fertilizer is safe and pollution -free.

4、Frontiers

We analyzed differences in soil nutrients, microbial community composition, and tobacco growth under different treatments. The results showed that, compared with other treatments, the combination of hole fertilization and T2 significantly promoted tobacco growth.

5、Influence of Foliar Fertilizer

The foliar fertilizer-spraying greatly affected the chemical composition in different position of leaf growth and the concentrations of 0. 2% foliar fertilizer could promoted the quality of tobacco leaf based on the integrated evaluation of smoking testing of top,middle and low position leaves.

Application of Soil Improvement and Fertilization in Tobacco Planting

This article analyzes the importance of soil improvement and fertilization in tobacco cultivation, explores several effective soil improvement methods, and proposes soil improvement and fertilization strategies that meet the needs of modern agriculture.

Effect of Timing Fertilizer Application on leaf yield and quality of

The Tobacco Research Institute of Tanzania (TORITA) through the project number TR102/TOR-20L/2020 funded the research titled ‘Effect of Timing Fertilizer Application on leaf yield and quality of tobacco’.

Effect of Nitrogen Fertilization on Growth and Photosynthetic Nitrogen

These results indicated that tobacco seedlings under high N application can maintain high net photosynthetic rate (Pn) but lower PNUE, will finally result in a decline in N use efficiency.

Frontiers

Several basic field experiments have been carried out in different tobacco planting areas in China to study the different effects of organic-inorganic fertilizer on tobacco.

Foliar fertilization is an effective method in tobacco cultivation, as it directly delivers nutrients to the plant’s leaves and stems, enhancing the quality and yield of tobacco leaves. Below is a detailed overview of the application methods and precautions for using foliar fertilizers in tobacco farming:

I. Selection and Proportioning of Foliar Fertilizers

1. Fertilizer Choice: Select foliar fertilizers based on the growth stage of tobacco and soil conditions. Common options include potassium dihydrogen phosphate, urea, and borax. Potassium dihydrogen phosphate is suitable during the early and mid-growth stages, promoting root development and disease resistance. Urea is applied later to provide essential nitrogen for leaf expansion.
2. Concentration Adjustment: Tailor the concentration and frequency of application to tobacco’s specific needs. Avoid excessive concentrations to prevent foliar damage or stress. Application frequency should align with growth phases to avoid over-fertilization, which may lead to leaf burn or reduced quality.
3. Mixed Application: Combining different foliar fertilizers can improve absorption efficiency. For example, mixing potassium dihydrogen phosphate and urea in appropriate ratios enhances complementary effects, supporting comprehensive leaf development.

II. Application Methods for Foliar Fertilizers

1. Sprayer Use: Utilize a dedicated sprayer to evenly coat tobacco leaves. Ensure leaves are adequately moistened without excess water, which could foster diseases. Adjust spraying direction and speed based on wind conditions to achieve uniform coverage.
2. Nozzle Configuration: Position nozzles according to plant height and leaf size. Spray from a close distance to facilitate rapid absorption. Optimize nozzle angles and distances to ensure even distribution while minimizing waste.
3. Timing: Apply foliar fertilizers during tobacco’s active growth phases for optimal results. This period coincides with peak nutrient demand, allowing quick replenishment. Avoid high-temperature periods, as extreme heat may degrade fertilizer efficacy.

III. Precautions for Foliar Fertilization

1. Avoid Overapplication: Excessive use can hinder plant growth or cause death. Strictly control dosages to prevent toxicity or quality loss.
2. Prevent Contamination: Minimize environmental impact by selecting eco-friendly fertilizers and cleaning residues post-application. Use personal protective equipment (PPE) to avoid skin or eye contact.
3. Timely Supplemental Fertilization: Combine foliar applications with other methods, such as root fertilization and organic fertilizers, to holistically meet tobacco’s nutritional needs and improve leaf quality.

foliar fertilization is a critical practice in tobacco farming. By selecting appropriate fertilizers, optimizing application techniques, and adhering to precautions, farmers can significantly enhance tobacco leaf quality and yield. Scientific management ensures healthy plant growth and superior crop outcomes.
