EC level affects nutrient contents of pepper (Capsicum annuum) grown on various soil textures
Salinity and soil texture has an impact on the uptake of nutrients. The effects of the saline irrigation waters were examined on nutrient contents of the pepper plant grown in different soil textures. Pepper plants were grown in pots filled with soils with clay, sand and clay loam textures. Irrigation water had EC values of 0.7 (control), 1, 2 and 3 dS m-1 prepared by addition of NaCl. The experiment was set up in a randomized factorial block design with four replicates. Increasing EC levels decreased the N content of leaf while increasing Ca, Mg, Na, Fe, Cu, Zn and Mn contents in clay. The treatments did not change the P content of leaf. Similarly in sand, the N contents of leaves decreased and increasing EC levels increased Na, Fe and Zn contents while P, Ca, Mg, Cu and Mn contents were not affected. In clay-loam, N, P, Ca, and Fe contents of pepper leaves were not affected by EC levels, but Mg, Na, Cu, Zn and Mn contents increased with increasing EC levels. Texture was significant on K contents where maximum leaf K content measured in clay. Results indicate that both soil texture and EC level of irrigation water should be taken into consideration for a productive agriculture.
