(1) Zero
(2) Three
(3) Two
(4) Four
The deficiency symptoms of S and Ca will appear first in
(1) Both in young and old parts
(2) Only in young parts
(3) First in old parts
(4) First in young parts
Why does S and Ca deficiency not found in older parts first?
(1) As they are immobilizable
(2) As they are very abundant in older parts
(3) As newer parts are already deficient

(1) N
(2) K
(3) S
(4) Mo
The following statements are correct except
1. Different plants respond differently to the deficiency of the same element
2. The deficiency of any element can cause multiple symptoms and that the same symptoms can be caused by the deficiency of other elements as well
3. Lack of N, K, S, Mo is responsible for cell division
4. There is a narrow range of concentration at which elements are optimum
