Explore key challenges in cumin cultivation, from soil selection to pest management. Designed for growers and enthusiasts aiming to improve cumin yield and quality.
Which type of soil provides optimal drainage and fertility for healthy cumin growth?
Explanation: Well-drained sandy loam is ideal for cumin because it prevents root rot and provides necessary nutrients. Heavy clay retains excess water leading to root diseases. Waterlogged peat can suffocate cumin roots, while rocky gravel offers poor anchorage and nutrient content.
A cumin field shows yellowing and wilting plants; lab analysis finds Fusarium fungi. What is the likely problem?
Explanation: Fusarium wilt, caused by Fusarium fungi, leads to yellowing and wilting in cumin. Downy and powdery mildew usually present as leaf spots or white film. Sun scorch damages leaves directly but does not typically cause wilting from the roots upward.
Which irrigation practice best reduces risk of cumin root diseases in semi-arid regions?
Explanation: Moderate, infrequent watering prevents both drought stress and waterlogged soils, minimizing disease risks. Continuous flooding causes excess moisture. Daily overhead can promote foliar diseases. Extended dry periods can stunt plant growth.
If cumin leaves turn pale green and growth is stunted, which nutrient is most likely lacking?
Explanation: Nitrogen deficiency typically causes pale leaves and poor growth in cumin. Potassium affects leaf edges and overall vigor. Calcium usually causes deformity, not general yellowing. Sulphur deficiency is less common and resembles nitrogen issues, but nitrogen is more likely.
A cumin crop suffers from small holes and chewed leaves; tiny larvae are visible. Which pest is the probable cause?
Explanation: Cutworms are larvae that chew on leaves, creating visible holes. Aphids suck sap but do not chew. Nematodes attack roots, not leaves. Spider mites cause stippling or webbing, not significant leaf chewing.
