This was not enough Z namakanjem Brez namakanja of50% water (Pk-Tv) Toèka venenja (Tv) Poljska kapaciteta (Pk) Padavine Kolièina namakanja state in the even for one irrigation for pepper. The water condition in the soil will therefore fall below the wilting point of the pepper– the first crop is close to soil being picked and so in the period of picking the first fruits, flowering the next in the third level and at the same time lush vegetation. For all three phases suitable, regular and enough water are a necessity. Irrigation From 12.7 to 15.7 one needs to add 20mm of water to the pepper as regards forecast to irrigation. The pepper needs to be watered twice a week, because the amount of organic substances in the soil and the depth of the profile assure that the water will retain in the area of the roots for so long. Just regular watering assures quality of the fruits as water does not run out not even for a day. Irregular watering, speculation of when and how rain will fall only cause poor quality crops, bad pollination and fertilization therefore deformation of crops or irregular shape. Also injuries to the lack of calcium are bigger and more regular as plants are not guaranteed a regular supply of water.
