Staking vs. Propping: A Comparison of Crop Support Techniques
Staking and propping are two different field management practices used to support crops in agriculture. Let me explain the distinction between the two:
Staking and propping are field management practices used to support crops. Staking is used for tall varieties like tomatoes, while propping is used for crops like bananas. Staking involves using stakes and tying the plant to keep it upright, while propping uses 'Y' shaped sticks to support weak stems. Both practices enhance crop productivity and reduce yield losses.

Describe the selection, preparation and raising of vegetative tea seedlings in the nursery22/10/2023 Vegetative Tea Seedling Nursery: Selection, Preparation, and Raising Techniques
The selection, preparation, and raising of vegetative tea seedlings in the nursery involve several steps to ensure the production of healthy and high-quality planting materials. Here is a detailed description of each stage:
Hardening off is the practice of gradually exposing the seedlings to environmental conditions outside the nursery. This process helps the seedlings acclimate to the field conditions before transplanting. During hardening off, gradually reduce the shade or polythene cover over a period of time. This exposure to increased sunlight and fluctuating temperatures enhances the resilience of the seedlings and prepares them for successful transplantation. By following these steps for selection, preparation, and raising of vegetative tea seedlings in the nursery, tea growers can ensure the production of healthy and vigorous planting materials, which will contribute to the establishment of productive tea plantations. Crop Nursery Management Practices for Healthy Seedling Growth
Crop nursery management practices involve a range of activities to ensure the healthy growth and development of seedlings. Here are some key management practices:
Advantages of Raising Tea in Polythene Sleeves: Easy Transplanting, Root Protection, and Long-Distance Transportation

Benefits of Rough Lemon Rootstock in Citrus Budding/Grafting: Compatibility, Disease Resistance, Adaptability, Vigorous Roots, Drought Tolerance
Here are five reasons why rough lemon is preferred as a rootstock during budding/grafting of citrus:
a) What is tissue culture?
Tissue culture refers to a biotechnological technique used to clone plants vegetatively. It involves the growth of plant cells, tissues, or organs in a controlled laboratory environment under sterile conditions. Through tissue culture, small pieces of plant tissue, such as cells or explants, can be multiplied and developed into whole plants, bypassing the traditional process of seed germination.
b) Outline 5 importance of tissue culture in crop propagation
The importance of tissue culture in crop propagation includes:
