Credit:2(1+1)

THEORY:
Agronomy, its scope and relationship with other sciences, Tillage and tilth, Seeds and sowing. Crop density and geometry, Crop nutrition, Manures and fertilizers.Nutrient use efficiency.Growth and development of crops.Plant ideotypes.Crop rotation and its principles.Study of crop adaptation and its distribution.Harvesting, threshing and Storage of field crops. Weeds – characteristics and classification. Crop – weed competition. Concept of weed management. Herbicides – Classification, selectivity and resistance of herbicide, allelopathic effect of weed.

PRACTICALS:

Identification of seeds and crop plants at different growth stages. Study of different tillage implements Identification of fertilizers and pesticides. Identification of weed flora in different field crops.Agro climatic zones of Goa and India Operational tillage viz., primary, secondary, inter-tillage. Sowing, harvesting, harvesting implements and working with them. Calculation of Plant Population, Seed rate, fertilizer and herbicide dose for different field crops. Methods of seed germination and viability test. Practice of seed treatments in different field crops. Computation of weed indices Application of manures and fertilizer in important field crops.Application of herbicides in different field crops. Yield contributing characters and yield estimation in different field crops.
