Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Multiple Regression

Multiple Regression

Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Light Acquisition

Light Acquisition

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Response Surface Methodology

Response Surface Methodology

Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:

Background:

Conventional rice planting methods in Southwest China exhibit suboptimal efficiency in agricultural input utilization.
This inefficiency limits both crop productivity and the achievement of environmental benefits.

Purpose of the Study:

To develop a machine-learning-based decision-making system for optimizing comprehensive benefits in rice production.
To identify specific input strategies for four conventional rice planting methods to enhance yield and environmental outcomes.

Main Methods:

Development of a machine-learning decision-making system.
Analysis of input adjustments (fertilizer and seed) for mechanical transplanting (MT), mechanical direct seeding (MD), manual transplanting (MAT), and manual direct seeding (MAD) methods.
Evaluation of yield, environmental impacts, and comprehensive benefits.

Main Results:

Mechanical transplanting (MT): Reduced N fertilizer by 16% and increased seed input by 9% improved yield and environmental benefits.
Mechanical direct seeding (MD): Reduced N fertilizer and seed inputs by 10-12% decreased environmental impacts.
Manual transplanting (MAT): Increased N-K fertilizers and seed inputs by 15-33% improved comprehensive benefits by 7-14%.
Manual direct seeding (MAD): Applied an N-P-K fertilizer ratio of 2:1:2 enhanced yield.

Conclusions:

The study provides tailored strategies for enhancing benefits across different rice planting methods.
The mechanical transplanting (MT) method demonstrates the greatest potential for optimizing comprehensive benefits, particularly in yield and environmental impact reduction.
The findings offer valuable insights for sustainable and productive rice cultivation in Southwest China.
