Description The present investigation entitled “Studies on Kinnow decline in relation to soil-plant
nutritional status”, was carried out on the fourteen year old Kinnow mandarin trees budded on
rough lemon planted at a spacing of 6 x 6m in a sandy loam soil at the Department of
Horticulture, Chaudhary Charan Singh Haryana Agricultural University, Hisar during the year
2009-10. There were no differences between the soil pH, electrical conductivity and calcium
carbonate of healthy and declining trees. The soil under the healthy trees had significantly
higher organic carbon (0.46%) than that under declining trees (0.35%). The nutrients viz., N, P,
Zn, Cu, Mn and Fe in the soil under healthy and declining trees did not differ significantly
except K. Leaf N, Zn, Cu, Mn and Fe were significantly more in the healthy trees. The
deficiency of N, P, Zn and Mn in the leaves of both categories of trees could be attributed to
low contents of these nutrients in the soil under healthy and declining trees.
Growth, yield and fruit quality were better in healthy trees as compared to declining
trees. The yield on kg per tree basis in declining trees reduced (8.43 kg/tree) as compared to that
in healthy trees (20.74 kg/tree). Low organic carbon, soil N, Zn and Mn content could be
associated with the declining problem of Kinnow.
