Concept:Several agronomic factors determine the success of seed sowing and subsequent crop growth in the field.
Explanation:Careful planning is needed before seeds are placed in the soil.
I. Time of sowing is important because planting at the right season provides suitable temperature and moisture for germination.
II. Plant density must be considered because correct spacing ensures adequate access to sunlight, water, and soil nutrients.
III. Depth of sowing also matters since seeds placed too deep or too shallow may fail to germinate and establish well.
IV. Method of sowing, including broadcasting, drilling, or dibbling, influences seed placement and soil coverage.
All four factors play an essential role in successful sowing.
Thus, the farmer must take every one of these factors into account when planting.
