Summary
This summary is machine-generated.Conventional tillage maximizes rice and wheat yields in India, despite alternative methods showing potential for soil health. Specific genotypes, Him Palam Lal Dhan 1 and HPW 368, consistently perform best.
Area Of Science
- Agricultural Science
- Agronomy
- Soil Science
Background
- The rice-wheat cropping system is dominant in North-Western India.
- Open burning of rice residue causes environmental and health issues, including greenhouse gas emissions and air pollution.
- Sustainable management strategies are needed to improve soil health and crop productivity.
Purpose Of The Study
- To investigate tillage-based cultivation, stubble retention, and integration approaches for the rice-wheat system.
- To enhance soil health features and improve crop yield and attributes.
- To evaluate the impact of different management strategies on soil nutrients and crop performance.
Main Methods
- A split plot experimental design with three replications was used.
- Four different cultivation methods were tested in main plots.
- Three genotypes each of rice and wheat were evaluated in subplots.
Main Results
- Residue application significantly increased soil nutrient concentrations (N, P, K, OC) compared to standard tillage (P < 0.05).
- Natural farming, zero tillage, and reduced tillage decreased rice yields by 34.0%, 16.1%, and 10.8%, respectively.
- Natural farming, zero tillage, and reduced tillage decreased wheat yields by 59.4%, 10.9%, and 4.6%, respectively.
Conclusions
- Genotypes Him Palam Lal Dhan 1 (rice) and HPW 368 (wheat) showed superior grain yields and yield components.
- Conventional tillage proved most effective for maximizing rice and wheat productivity.
- While alternative methods impact soil nutrients, conventional tillage currently offers higher yields.

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.
As humans' understanding of genetics advanced, improved crop varieties could be achieved more quickly. Artificial selection could be more directed, and crop varieties enhanced for favorable traits more quickly to produce better, more robust, or more palatable...
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...
Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.
Plant tissue culture depends on the ability of plant tissue to give rise to an entire new plant when provided with a growth medium and appropriate environment. This ability of plant cells or tissues is termed ‘totipotency.’

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.
Under normal conditions, water taken up by the plant evaporates from leaves and other parts in a process called transpiration. In times of drought stress, water that evaporates by transpiration far exceeds the water absorbed from the soil, causing plants to wilt. The general plant response to drought stress is the synthesis of hormone...
