TLE Grade 7 Quarter 2 - AFA Weeks 2-3 :CROP CARE AND MAINTENANCE, HARVESTING AND POST HARVESTING

This part focuses on post-harvest practices. It covers vegetable storage (common/unrefrigerated and cold/refrigerated storage) and the factors that influence produce quality during storage. It also details pre-marketing operations like washing, trimming, waxing, pre-cooling (hydrocooling, contact icing, vacuum cooling, air cooling), grading, and packaging.

This section discusses providing support for climbing plants using trellises made of wood or metal. It then moves into harvesting, explaining that crops are harvested at maturity using traditional or modern methods, and highlighting factors determining harvest date, such as genetic composition, planting date, and environmental conditions.

The final section covers the selling process, differentiating between retail and wholesale marketing. It concludes by offering additional practices to boost crop productivity and farm profitability, such as diversifying crops, enhancing pollinators, employing eco-friendly weed control, improving soil quality, managing costs, and creative marketing strategies.

This section introduces the core topics of crop care, maintenance, harvesting, and post-harvesting practices. It also defines key terms such as 'crops', 'pesticides', 'herbicides', 'cultivation', 'irrigation', 'trellis', and 'fertilizer', laying the groundwork for understanding agricultural processes.

The video categorizes crops into various types: food crops (field crops and root crops), cash crops, feed/forage crops, fiber crops, oil crops, ornamental crops, and industrial crops. Examples are provided for each category to illustrate their purpose and use.

Crops are classified by their growth habits (herb, vine, liana, shrub, tree, evergreen, deciduous) and life cycles (annual, biennial, perennial). The section also highlights crucial factors influencing crop production: water, soil, wind, temperature, sunlight, seed selection, knowledge, and proper crop care and maintenance.

This part details the initial stages of crop care: cultivation (stirring soil for weed and pest control), seed sowing and seedling planting (emphasizing good quality seeds, proper depth, and spacing), and irrigation (various methods like manual, drip, and sprinkler irrigation, tailored to different crop needs).

The video further explains crop maintenance, including fertilizer application (natural, organic, or commercial to enrich soil nutrients), weed control (manual, mechanical, and chemical methods using selective or non-selective herbicides), and pest and disease control (using pesticides and encouraging eco-safe practices).
