A farmer plants maize at a spacing of 4m x 6m. If the farmer has a land area of 1 hectare (10,000 square meters), what is the maximum number of maize plants that can be planted in this field?
सही उत्तर: ग) 7500
The correct answer is (2) 5000. First, calculate the area per plant: 4m x 6m = 24 square meters. Then divide total area by this: 10,000 sq meters / 24 sq meters/plant = 416.67 plants. Rounding to the nearest whole number gives us approximately 5000 plants. The other options are significantly lower than what can be achieved with this spacing.

Azolla, a water fern, plays a crucial role in rice cultivation. Its ability to fix atmospheric nitrogen contributes significantly to soil fertility. What is the primary mechanism by which Azolla achieves this nitrogen fixation?
सही उत्तर: ख) Through symbiotic association with cyanobacteria
The correct answer is (1) Through symbiotic association with cyanobacteria. Azolla forms a symbiotic relationship with *Anabaena* cyanobacteria, which possess the enzymes necessary to convert atmospheric nitrogen into ammonia – a vital nutrient for plant growth. The other options are incorrect: photosynthesis doesn’t directly produce ammonia, Azolla doesn't absorb nitrogen from rainfall, and it doesn’t break down organic matter to release nitrogen.
