Soil physico-chemical and biological properties were assessed in Mango cv. Langra orchards of farmers’
field in surrounding the ICAR-CISH, Rehmankhera, Lucknow and related with the productivity of
orchards. Generally, orchards with higher productivity level had registered higher amounts of nutrients,
biological activities and lower physical constraints. Soil samples at three depth (0-10, 10-20 and 20-30
cm) were collected from the tree basin were subjected to laboratory analysis during 2017-19. Data
showed that enzymatic activities varied across orchards and depths. The dehydrogenase activity was
estimated @ 1.14 (0-10 cm soil depth) to 0.16 (20-30 cm soil depth) μg TPF g-1 h-1 and fluorescein
diacetate activity @ 386.89 (0-10 cm) to 161.11 (20-30 cm) μg fluorescein g-1 h-1 respectively. The soil
reaction of the orchard indicated higher than near neutral values of 7.6; available P, K and soil organic
carbon decreased down the depths (27.97 to 10.77 mg kg-1, 116.95 to 76.62 mg kg-1 and 0.45 to 0.34%)
at top soil (0-10 cm) to subsoil (20-30 cm) respectively. Wide coefficient of variations in micronutrient
contents was noted. Depth wise variability in soil physical properties was estimated. The study inferred
enormous scope to enhance yield in mango cv. Langra under subtropical condition of this region with
improved management of soil moisture.
