Abstract/Description: | The distribution of K forms (water soluble, exchangeable, non-exchangeable, mineral and total K) in two apple(cv. Royal Delicious) orchards differing in fertilizer management practices located in the Kumaon region ofUttarakhand was investigated. The apple orchard at Mukteshwar is managed by the conventional fertilizermanagement practice, and the other at Dutkanedhar is managed organically. At Mukteshwar, the distribution ofwater soluble, exchangeable, non-exchangeable, mineral and total K was 0.23, 0.86, 5.46, 78.2, and 86.7 cmolkg-1, respectively.Further, soil analysis revealed that both the soils contain very high levels of available K (>350mg kg-1). Leaf K content in orchard of Dutkanedhar was deficient (0.81%) with the appearance of K deficiencysymptoms as necrotic leaf edges; whereas, the same at Mukteshwar was recorded as sufficient (1.93%). Thepositive and significant correlations were observed between available and water soluble (r= 0.78), available andexchangeable (r= 0.45), exchangeable and non-exchangeable (r= 0.33), non-exchangeable and mineral (r=0.77) and mineral and total K (r= 0.95) in the orchard of Mukteshwar. It was concluded that K requirement inapple could not be satisfied entirely through addition of organic manures only, and thus, K fertilization isindispensable. |
