Do plants grow taller with salt water or fresh water?
Do Plants Grow Better in Saltwater or Freshwater? Plants grow best with the water for which they are adapted: marine plants such as kelp grow best in saltwater, while land plants grow best in freshwater. Too much salt hurts land plants.
What is called Rabi crop?
The crops that are sown in the winter season are called Rabi crops. (also known as the “winter crop”) in India. The Rabi means, when the crop is harvested.

Why is water so important in the production of crops?
Water is one of the most important inputs essential for the production of crops. Plants need it continuously during their life and in huge quantities. It profoundly influences photosynthesis, respiration, absorption, translocation and utilization of mineral nutrients, and cell division besides some other processes.
Why is water so important to agriculture and food security?
Water use in agriculture is at the core of any discussion of water and food security. Agriculture accounts for, on average, 70 percent of all water withdrawals globally, and an even higher share of “consumptive water use” due to the evapotranspiration requirements of crops.
How does water affect the growth of plants?
It profoundly influences photosynthesis, respiration, absorption, translocation and utilization of mineral nutrients, and cell division besides some other processes. Both its shortage and excess affect the growth and development of a plant directly and, consequently, its yield and quality. Rainfall plants.
How much water does agriculture use each year?
On average, about 40 percent of water withdrawn from rivers, lakes and aquifers for agriculture effectively contribute to crop production, the remainder being lost to evaporation, deep infiltration or the growth of weeds. Consequently, the current global water withdrawals for irrigation are estimated to be about 2 000 to 2 500 km 3 per year.
What are the functions of water in agriculture?
In crop agriculture, water is an important climatic factor. It affects or determines plant growth and development. Its availability, or scarcity, can mean a successful harvest, or diminution in yield, or total failure. Water maintain cell turgidity for structure and growth. Transporting nutrients and organic compounds throughout the plant.
How does water affect the performance of crops?
Water affects the performance of crops not only direclty but also indirectly by influencing the availability of other nutrients, the timing of cultural operations, etc. Water and other production inputs interact with one another. In proper combinations, the crop yields can be boosted manifold under irrigated agriculture.
What is the role of water in plants?
Inevitably, without water, living things are impossible to exist. The role of water in the plant’s life is mainly on hydration, transpiration, and dry matter production of plants . Decreasing water loss and irrigating to the level of optimum water availability enhances plant growth, development, and yield.
How does water use in agriculture affect food security?
Water use in agriculture is at the core of any discussion of water and food security. Agriculture accounts for, on average, 70 percent of all water withdrawals globally, and an even higher share of “consumptive water use” due to the evapotranspiration requirements of crops. Worldwide, over 330 million hectares are equipped for irrigation.
