1、Flowering dynamics, pollen, and pistil contribution to grain yield in

The reproductive stages, i.e. tassel emergence, pollen shedding, silk emergence, blossoming and end of shedding were recorded according to the days after sowing (DAS).

2、Detection of the Progression of Anthesis in Field

The tassel of the maize plant is responsible for the production and dispersal of pollen for subsequent capture by the silk (stigma) and fertilization of the ovules.

【Result】 High temperature, drought and combined stress resulted in significant reduction in the tassel branch number, tassel central branch spikelet number and tassel branch spikelet density in maize, and these three parameters of T treatment were 17.31%, 15.70% and 13.56% lower than that under CK, respectively; D and TD treatments were 33.85%, ...

Maize Tasseling Stage Automated Observation Method via Semantic

Abstract: Accurately observing the maize tasseling stage (MTS) is critical for optimizing yield in agricultural ecosystem research. Despite some success in automated observation attempts, automating the tasseling stage remains an open problem.

ese variable environments. Maize production models include the Runge-Bend Model (Runge & Bend, 1975), the Splinter Model (Splinter, 1974), SIMAIZ (Dun can, 1975), the Bio-photo-thermal Model (Coligado and Brown, 1975), the Energy-Crop Growth Model (Coelho & Dale, 1980), CORNF (Stapper & Arkin, 1980), and CERES-Ma.

A study on natural recovery of tassel fertilization and doubling method

Doubling method is the technical barriers in maize haploid breeding. It was very important to establish the independent intellectual property rights for doubling method. In this experiment, the maize haploid inducer, TG15, was used for producing maternal haploids.

Maize pollination and fertilisation

Successful pollination of the maize plant depends on several factors such as the production of sufficient and viable pollen during the tassel and silking stages.

Maize tassel number and tasseling stage monitoring based on

Because maize is considered to enter the tasseling stage when half of the maize plants have their tassels emerged (Hanway, 1966), the identification of the tasseling time depends on the dynamic counting of the tassel number.

Key Growth Stages of Maize

Maize crop requires careful management from germination to maturity. Familiarity with these growth phases empowers farmers to make informed decisions on irrigation and fertilisation timing for optimising resource use and minimising environmental impact.

The tassel emergence stage is a critical phase in maize growth, and proper management and fertilization during this period are essential for enhancing yield and quality. The following recommendations outline key fertilization practices:

1. Base Fertilizer Application: Prior to maize planting, deeply plow the soil, remove weeds, and apply an appropriate amount of organic fertilizer or compound fertilizer based on soil fertility. Organic fertilizer provides abundant nutrients, while compound fertilizer supplies major elements like nitrogen (N), phosphorus (P), and potassium (K) as needed. Ensure even distribution of base fertilizer to guarantee adequate nutrition for all plant parts.

2. Topdressing: Around the jointing stage, topdressing should be conducted according to maize growth conditions and soil fertility. This practice replenishes nutrients consumed during growth, promoting healthy development. Carefully select fertilizer types and application methods to avoid over-fertilization, which may damage seedlings or reduce grain quality.

3. Foliar Spraying: A rapid way to supply nutrients, foliar spraying addresses deficiencies by applying diluted solutions directly onto leaves. Use appropriate concentrations to prevent leaf burn.

4. Soil Amendment: Incorporate soil conditioners like lime or gypsum before and after tasseling to improve soil structure, pH balance, water retention, and aeration, benefiting root growth.

5. Micronutrient Fertilization: Maize requires essential micronutrients such as iron (Fe), zinc (Zn), manganese (Mn), and boron (B). Apply micronutrient fertilizers like zinc sulfate or manganese sulfate to supplement these elements, supporting optimal growth and productivity.

6. Balanced Fertilizer Ratios: Tailor fertilizer blends to the maize growth stage and soil analysis. A general N-P-K ratio of 1:0.5:0.5 is recommended, with additional trace elements like molybdenum (Mo), copper (Cu), or iron as required.

7. Timing of Fertilization: Target fertilization, especially topdressing, around the jointing stage when maize has high nutrient demands. Timely applications ensure efficient uptake and support vigorous growth.

8. Fertilizer Quantity: Determine application rates based on crop condition and soil tests. Typically, allocate approximately 60% of annual fertilizer needs to base application and 40% to topdressing. Avoid excessive use to prevent nutrient burn or compromised quality.

effective fertilization during maize's tassel emergence stage involves strategic use of base fertilizers, timely topdressing, foliar sprays, soil amendments, micronutrient supplements, balanced ratios, and mindful application timing and quantities. Adhering to scientific principles and tailored approaches will maximize yields and profits.
