The effect of temperature and soil humidity on the growth at Pisum sativum L. subsp. sativumvar. Sativum
Ivanka Mitova, Vesselina Vassileva, Viktoria Necheva
Abstract: Pots experiment with green peas was carried out in two climate chambers – KNER-2 and KNER-4, with air temperatures of 15 and 21оС. The illumination in both cameras is 18,000 lx. Up to the massive germination in all pors was maintained 70% soil moisture , after which the vessels were divided into three groups, in which three moisture regimes of the soil are maintained by daily watering in the weighing mode respectively – 50%, 70% and 90% soil moisture.
It was found that the air temperature of 15°C was insufficient for the normal sprouting of plants, with a combination of high soil moisture and 90% MOP. At the same time, these plants have the best vegetative development (height and mass of the stem and leaves). The best reproductive development(number and mass of peppers) are plants at 70% SM and 15°C and at 70% SM and 21°C. The highest dry mass and total sugars content are the 50% PWC, 21оС, and 70% SM, 21оС temperature.
