1 Use of fertilisers and pesticides of biological origin
2 IPM(Integrated Pest management)
3 Depending on predation in nature
4 All of the above
Explanation:
Organic farming includes several methods to enhance soil fertility. In such farming, methods of biological origin are used, e.g., biopesticide, biofertilisers, IPM (Integrated Pest Management), basing on predation interactions etc.

Assertion : A gene Bacillus thuringiensis is incorporated in plant genome to increase their yield. Reason : Bacillus thuringiensis has \(\mathrm{Bt}\) toxin producing gene, which will kill the larva of insects.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Bacillus thuringiensis is a gram positive soil dwelling bacterium, commonly used as biological pesticide. In 1976 Robert A Zakharyan reported the presence of a plasmid in a strain and suggested the plasmid involvement in endospore and crystal formation. Spores and crystalline produced by this have been used to control pests so plant yield also increased e.g, Cotton.

An important part of the biological farming approach is i. To become familiar with the various life forms that inhabit the field ii. Predators as well as pests, and also their life cycles iii. Patterns of feeding and the habitats that they prefer.
1 Only i, ii
2 Only i, iii
3 Only ii, iii
4 All of them
Explanation:
The important part of the biological farming approach is to become familiar with the various life forms that inhabit the field, predators as well as pests, and also their life cycles, patterns of feeding and the habitats that they prefer. This will help develop appropriate means of biocontrol.
