Given information is that total mass of water required for the growth of a plant is 285 kgs, and mass of the marketed crop is 19 kgs. Find the transpiration ratio?

Correct Answer: 15
We have transpiration ratio (TR) = (total mass of water transpired by the plant during its growth / mass of dry matter produced) = (285/19) = 15.

A crop is being tested in the lab to its loss due to transpiration. Given that initial weight of instrument is 100 kgs, and final mass of instrument is 150 kgs. The amount of water added during full growth of plant is 70 kgs. Find the loss due transpiration when the method used is phytometer method?

Consider the following statements and choose the correct answer:
1. Transpiration usually occurs during day-time whereas guttation takes place in night
2. In transpiration water comes out in the form of liquid, whereas in guttation the water is given off in the form of vapour
3. Transpiration water is pure but guttation water contains inorganic salts and sugars
4. Transpiration is a controlled phenomenon whereas guttation is an uncontrolled phenomenon

Let us consider in a given area the plantation of a certain crop takes 20 days, and the total water depth required by this crop is 80 cm on the field. Find the duty of irrigation water required for the crop during this period. (

In a process, 5 Kgs of water is added to a container and after some interval 3 Kgs of water is taken out. If finally there is 7 Kgs of water then how much water was there in the very beginning?

The average weight of A, B and C is 40 kgs. Weight of C is 24 kgs more than A’s weight and 3 kgs less than B’s weight. What will be the average weight of A, B, C and D, if D weights 15 kgs less than C?

Which of the following statements about transpiration are correct? Statement 1: Low temperature increases the transpiration rate. Statement 2: Transpiration leads to water and vapor loss.

Study the following statements.
1. Excretion of water in the form of liquid droplets from leaves or uninjured plant parts is called gullation.
2. Transpiration help in ascent of sap.
3. Small opening in the leaf meant for gaseous exchange and transpiration is called stomata.
Which of the statements given above are correct ?

Given that a particular crop requires about 20 cm depth of water at an interval of 40 days, and the base period is 400 days. Find the delta for the crop? Now using this delta find the duty of water for the crop?

What is the monoisotopic and average mass of valine? Given data: Mass of the most abundant isotope of Carbon (C°)=12.0000, Mass of most abundant isotope of Hydrogen (H°)=1.0078, Mass of most abundant isotope of Oxygen (O°)=15.9949, Mass of most abundant isotope of Nitrogen (N°)=14.0031, The average mass of Carbon (C)=12.011, The average mass of Hydrogen (H)=1.008, The average mass of Oxygen (O)=15.999, The average mass of Nitrogen (N)=14.007.

At a certain place, the transplantation of a crop takes 15 days, and the total depth of water required by the crop is 90 cm on the field. During the plantation rain falls and about 20 cm is utilised to fulfil the demand. Now determine the duty of irrigation water required during the plantation.
