Abstract: Research carried out by Aleksandras Stulginskis University Laboratory of Agrobiotechnology, 2012–2013. Peas 'Ilgiai' sown in 0.16 mx 0.23 m (height x diameter) vessels with the substrate (pH – 6.31, P2O5 – 633.94 mg kg-1, K2O – 912 mg kg-1). The experiment was conducted 6 replicates of 5 plants in container. Plants cultivated at climatic chamber at 20/18 °C (day / night) temperatures, 16/8 hours. (day / night) photoperiod, 50 micromole m-2 s-1 lighting conditions. Plants cultivated at climatic chamber above conditions and the moisture deficit in the substrate. Drought investigation launched after three weeks of sowing. The highest chlorophyll a and b peas (respectively 2.501 and 0.821 mg l-1) observed at 8 days after watering. These variants chlorophyll a and b, compared with controls, reliably increased by 0,830 and 0,285 mg l-1 (49,67 and 53,17 %). After 8 days after watering, peas carotenoid content the maximum – 1,059 mg l-1. Compared with controls, these variants carotenoid content increased in 0,366 mg l-1 (52,81 %)
