The investigations were conducted to determine the period of cultivating and harvesting, and the effect of casamino acid on chlorophyll content in leaves of Amaranthus viridis. The seeds were sowed in April and August.
1. The growth was better on sowing in April, that is, the dry weight of leaves was more than three times on sowing in August.
2. The chlorophyll content more decreased, as dry weight of leaves more increased.
3. The chlorophyll content was higher during from early in June to early in July on sowing in April, another during from the middle of September to October on sowing in August; its maximum content was 1.46 percentage in the former and 1.41 percentage in the latter.
4. The yield of chlorophyll increased from late in June to late in July on sowing in April, its maximum yield on sowing in April was more than 2.5 times on sowing in August.
5. The treatment of 2, 000ppm casamino acid increased the content of chlorophyll b, but did not the growth and the content of chlorophyll a.
