Troublingly, the footprint of poppy cultivation continued to expand across Afghanistan, as it spread outside the southern and western regions where the overwhelming majority of opium is produced.
Though rice cultivation continued as an important activity, paddies had to be terraced, and the flow of water had to be regulated to suit the undulating land.
The cultivation continued at 20 °C for additional 15 h.
The results showed that organic N and amino acid N dominated the available N derived from fertilizer N, but their contents decreased significantly as crop cultivation continued.
The cultivation continued in a batchwise manner under laboratory conditions at 22°C, using a shake flask equipped with a stirrer and containing a working volume of 0.6 L, gassed with a sterile mixture of H2 O2 CO2 in variable ratios.
The photosynthetic activity of H. cervicornis recovered and was above initial activity after a period of cultivation, but it decreased if cultivation continued too long.
Cell cultures were mailed to the Institute of Physiology and Ecology, Shanghai (Laboratory of Prof. Zheng), and the cultivation continued (as liquid suspension) as described above.
When the optical density at 660 nm of the culture reached 0.5, 1 mM IPTG was added to the culture medium and cultivation continued at 30°C for four hours.
The cells were cultivated at 37 °C and 120 rpm and induction was carried out at an OD600 of 4. Subsequently, the cultivation was continued to an overall cultivation time of 24 h, starting from inoculation.
