Abstract
We assured the growth response and K uptake of wheat (cv. Inqlab-91) and oat (cv. S-2000) to K application and irrigation with canal and distilled water in a green house experiment. The surface (0-15cm) and sub-surface (15- 30 cm) samples each of the two soils were used in the study. The soils had 145-155 mg kg· 1 NH40Ac extractable K. The soils were exhausted for their K in the green house fora total of 84 days (D) by growing consecutively wheat (Triticim astivum L.) (42 D), and oat (Avena sativa L.) (42 D). Biomass accumulated by the both crop species was significantly (P < 0.01) different on the different soil types along with different source of irrigation water. Total K uptake (64-120 mg K per pot) and concentration of K in the two plant species was also significantly different on the different soils. Various plant species utilized 32-76% of their total K uptake from NH\ nonexchangeable K reserves of soils. Key words: Wheat, K uptake, oat, irrigation water (I.W.)
