Phosphorus deficiency leads to stunted growth, purplish coloration of leaf tips and margins, and abnormally dark green leaves.

Maize possesses the highest yield potential among cereals, which is why it is popularly called the “Queen of Cereals” in agronomy.

Sugarcane is considered mature when the Brix value ranges between 16–18, measured from juice taken from the middle portion of the stalk.

Pearl millet (bajra) has the highest mineral content (around 2.7%) among cereals, making it nutritionally rich.

CSH-1 was the first sorghum hybrid released in 1964 and marked the beginning of hybrid sorghum cultivation.

Chickpea/Bengal gram is botanically known as Cicer arietinum.

Under proper irrigated management, gram yields about 20–25 quintals per hectare.

Hordeum vulgare is six-rowed barley in which all three spikelets at each node are fertile, forming six distinct rows around the rachis.

Chickpea possesses a well-developed tap root system.

Maize is a monoecious plant (separate male and female inflorescences on same plant) and is predominantly cross-pollinated due to wind pollination.

Maize protein ‘zein’ is deficient in lysine and tryptophan, making maize nutritionally poor in essential amino acids.

Gasohol is prepared by mixing 80% petrol with 20% alcohol (ethanol derived from sugarcane) and is used as automobile fuel.

Saccharum officinarum is called Noble cane. It is a tropical cane with thick, juicy stalks and low fiber content (2n = 80).

TIBA (Tri-iodo benzoic acid) @ 75 ppm is used for chemical nipping in gram.

Barley has higher tolerance to saline and alkali soils compared to other cereal crops, making it suitable for marginal lands.

Zinc deficiency in maize causes “white bud” symptom, where apical leaves turn white due to impaired chlorophyll formation.

In 1961, four double cross hybrids—Ganga-1, Ganga-101, Deccan, and Ranjeet—were released under the All India Coordinated Research Project on Maize.

Chickpea requires a cloddy and rough seed bed to ensure proper aeration, as it is highly sensitive to poor soil aeration.

Simazine (0.5–1.0 kg) as the commonly used herbicide in maize cultivation.

Ratooning Stunting Disease (RSD) is caused by Clavibactor xyli, a bacterial pathogen affecting vascular tissues.

Pre-flowering and pod development are the most sensitive stages for moisture stress in gram.

The concept of crop logging in sugarcane was developed by H.F. Clements in Hawaii.

The sour taste is due to malic acid (90–96%) and oxalic acid (4–10%).

The terminal male flower cluster in maize is called tassel. It is a branched panicle bearing pollen (staminate inflorescence).

Excess nitrogen during ripening decreases sucrose content in sugarcane.

D.F. Jones (1920) proposed the double cross technique for hybrid seed production, which later became widely used, especially in India.

The recommended spacing between rows in sugarcane is 90 cm for proper growth and management.

Shoot borer (Chilo infuscatellus) damages the growing point and produces the typical “dead heart” symptom.

Recommended seed rate for gram is 80–100 kg per hectare for optimum plant population.

About 35,000–40,000 three-budded setts per hectare are required, usually obtained from 75–80 quintals of cane.

In H. irregular, the lemma does not bear awns or hoods, which differentiates it from H. vulgare where florets are awned or hooded.

Late sowing increases infestation of pod borer (Helicoverpa armigera), leading to heavy yield loss.

Grassy shoot disease is caused by phytoplasma, leading to excessive tillering and pale shoots.

Red rot is caused by Colletotrichum falcatum and shows characteristic reddening of the stem pith.

Barley grains are primarily used for malt production, which is utilized in breweries for making beer, alcohol, vinegar, and yeast.

Striga is a partial root parasite that attaches to host roots and extracts nutrients, severely reducing yield.

Chickpea is a C₃ plant and performs photosynthesis through the C₃ pathway

The ideal sowing window for gram is 15 October to 20 October to ensure proper growth and avoid frost damage.

Dent corn (Zea mays indentata) has a tooth-like indentation on the kernel and is extensively grown in the USA.

Saccharum spontaneum is the wild species of sugarcane.

For proper maturity, the Fehling test solution reading should indicate less than 0.5% glucose.

Saccharum barberi (Indian cane) has low sucrose, high fiber content, and short, thin stalks.

The first inter-specific hybridization (1947) for Napier grass involved Pennisetum purpureum × Pennisetum glaucum, leading to improved forage types.

maize is particularly sensitive to water logging, which adversely affects root respiration and plant growth.

H. distichon is strictly two-rowed barley and only the central spikelet is fertile, while lateral spikelets are sterile.

Adsali planting is done in June–July and takes 15–18 months for harvesting, commonly practiced in Maharashtra (South India).

The recommended optimum plant population for Kharif maize is 65,000–70,000 plants per hectare to achieve better productivity

Flint corn (Zea mays indurata) has hard and smooth kernels and is commonly cultivated in India.

The inflorescence of sugarcane is called an “Arrow.”
