Total Weight of Seeds (\( TWs \)):

\[ TWs = \frac{N_h \times N_{sh} \times S_w}{1000 \times E} \]

Where:

• \( TWs \) is the total weight of seeds needed, in kilograms (kg).
• \( N_h \) is the number of hills.
• \( N_{sh} \) is the number of seeds per hill.
• \( S_w \) is the specific weight of seeds, in grams per seed (g/seeds).
• \( E \) is the emergence, in decimal form.
