Chickpea is the most common and widely cultivated pulse crop in India. It accounts for around 40% of the total production of pulses.
Moreover, India is the largest chickpea producer in the world with 99,37,990 tons of production per year. Our country alone produces more than 60% world's chickpeas.

Frankenstein food is such foodstuff that is prepared from genetically modified crops (GMOs). GMOs are any organism whether it is a plant, animal, or microbe whose DNA has been altered using genetic engineering techniques to modify the yield and qualities for the welfare of the society.
Genetically modified maize is Frankenstein food.

Nitrogen is the most important essential nutrient required by plants for proper functioning.
Its deficiency in maize can cause yellowing of leaves from tip to base in V shaped pattern. It tends to show stunted or sparse growth. The oldest leaves show discolouration and necrosis.

Anemometer is an instrument that is used to measure wind velocity, wind pressure, and its direction. It counts the number of rotations, which is used to calculate wind speed.
Anemometer is derived from the Greek word anemos which means wind. This is a widely used instrument in meteorology.

Sesbania rostrate is a small semi-aquatic leguminous plant that has a double symbiotic relationship with nitrogen fixing bacteria.
It forms a symbiotic relationship with Gram–negative rhizobia which leads to the formation of nitrogen fixing nodules on both stem and roots. Because of this reason, it is mainly used as green manure to improve soil fertility.

Temporal intercropping is the practice of sowing a fast-growing crop with a slow growing crop so that the fast-growing crop is harvested before the slow-growing crop starts to mature.
Thus this practice results from growth patterns of the component crops differing in time.

tuberization in potatoes is a complex biological phenomenon of the potato plant which regulates the induction of tubers. The improved tuber yield and its quality are affected by several environmental cues, genetic factors and plant nutrition.
Under environmental cues, temperature plays an important role. The ideal temperature for the tuberization process is 18°C.

NRRI is the National Rice Research Institute is located at Cuttack, Odisha in the year 1946 with an experimental farm land of 60 hectares.
The mission of this institute is to develop and disseminate eco-friendly technologies to enhance the productivity, profitability and sustainability of rice cultivation. Its goal is to ensure the food and nutritional security of the present and future generations of rice producers and consumers.

HCl is a strong acid and it dissociates into ions completely.
HCl (aq) 0.01 M → H⁺ (0.01 M) + Cl⁻ (0.01 M)
[H⁺ (aq)] = 0.01 M = 1 × 10^-2
pH = - log₁₀ [H⁺ (aq)]
pH= - log₁₀ [1 × 10^-2]
therefore pH = 2

Production of sugarcane is highest in Uttar Pradesh followed by Maharashtra in India. But productivity wise, Tamil Nadu stands first with over 100 tons per hectare followed by Karnataka and Maharashtra. Bihar has the lowest productivity among the major sugarcane producing states.
