Which agricultural practice is missing from the list: Irrigation, Removal of weeds, Preparation of soil, Storage of food grains, Sowing, Adding manure and fertilizers?
The missing agricultural practice is harvesting—the critical stage where mature crops are cut, gathered, and prepared for threshing and storage. Harvesting represents the culmination of months of agricultural effort and must be timed precisely. Harvesting too early results in immature grains with poor quality and lower yields, while delayed harvesting can lead to grain shattering, pest damage, bird attacks, and quality deterioration from weather exposure. <

How does this practice help in the replenishment of soil?
The legume-wheat rotation creates a natural soil fertility cycle that reduces dependency on chemical fertilizers while maintaining high productivity levels. Leguminous plants possess a unique ability to fix atmospheric nitrogen through a symbiotic relationship with Rhizobium bacteria residing in root nodules. These bacteria convert atmospheric nitrogen into ammonia and other nitrogen compounds that plants can use. When legume crops are grown, they can add 50-150 kg of nitroge

Why is it necessary to dry harvested food grains before storage?
Proper drying of harvested grains is absolutely critical for preserving grain quality, preventing losses, and ensuring food safety during storage periods that may extend several months. Freshly harvested grains typically contain 20-25% moisture content, which creates an ideal environment for microbial growth, particularly fungi and bacteria. These microorganisms cause grain spoilage, producing mycotoxins that make food unsafe for human and animal consumption. High moisture also promot

What are sclereids and what is their function in plants
Sclereids are a type of sclerenchyma cell that provides mechanical support and protection to plant tissues. Unlike the elongated fibers, sclereids are typically short, irregularly shaped cells with extremely thick, lignified secondary walls that make them very hard and rigid. They are found in various plant parts including seed coats (providing hardness), nutshells, pulp of fruits like pears (causing the gritty texture), and leaf tissues. Sclereids protect seeds, deter herbiv
