Q. Which are the potential hybrid varieties of cotton suitable for northern zone in India?
Ans- - For the North zone, particularly for the high-yield potential irrigated tracts of Punjab, Haryana and Rajasthan, the recent identification of intra-hirsutum hybrids like Fateh, HHH 81, Raj HH 6; Asiatic hybrid (intra-arboreum) LDH 11, and a few interspecific hybrids with long staple and early maturity have shown possibility of commercial success of hybrid cottons in north

Q. How to control root rot disease in cotton?
Ans- Seed treatment with Brassicol at the rate of 5 g per kg seed or soil application at the rate of 10 kg per hectare helps in checking the losses from seedling root rot. Adopting good crop rotation for three or four years could also help controlling root rot.

Q. What is the need of Integrated Pest Management in cotton?
Ans- Cotton crop is subject to attack by a number of insect pests. It constitutes a major limiting factor in cotton production. Over 50% of the total insecticides used in agriculture go in cotton where pest control accounts for 35-60% of the total cost of cultivation. The overuse has led to development of resistance to pesticides, widespread killing of natural enemies leading to resurgence of secondary pests and increased number of pest control failures. This very fact forced scientist to take a fresh look on cotton pest control strategies and necessitated the approach towards developing sustainable cotton pest management programmes with minimum reliance on the use of pesticides. The IPM modules are based on eco-friendly approaches like field sanitation, crop residue removal, mechanical control, crop rotation, trap cropping, pest monitoring with pheromones and conservation and release of natural enemies and ETL-based use of soft chemicals.

Q. which varieties of jute are dominating in west Bengal?
Ans-Capsularis’ and ‘Olitorius’ are the two dominating varieties widely grown in Southern west Bengal.

Q. what are the recommended practices for weed management in jute?
Ans- Weeding, especially in the early stage, is a must. For a broadcast crop, the pre-sowing application of 2,2,3,3 tetrafluorpropionate of sodium proved to be beneficial. A post-emergence application of mono-sodium methanarsonate with or without 2,2 dichloropropionate, as a directed spray, proved to be beneficial in row-cropped fields Yields, with two hand-weeding, however, are significantly superior and constitute the prevailing standard practice. Smothering the weeds between rows with a wheel-hoe saves labour and helps to mulch the soil
