What is the most essential element for a crop?
PRIMARY (MACRO) NUTRIENTS
Nitrogen (N), Phosphorus (P), and Potassium (K)
are the most frequently required in a crop fertilization program. Nitrogen is necessary for the formation of amino acids, proteins, DNA and RNA. It is essential for plant cell division and vital for plant growth.
Where is the best place for rice to grow?

Why is rice not grown in desert?
Answer :
because rice needs much quantity of water and in desert there plenty of water
. and rice cannot grow on sandy soil.
How do you increase rice yield?
The three factors that could contribute to increased rice productivity are: (a)
developing new rice varieties including hybrids with higher yield potential
; (b) minimizing the yield gap between what is currently harvested by farmers and the achievable highest on-farm yield of varieties they grow; and (c) reducing the …
What is the best organic fertilizer for rice?
