Abstract
On global scale soil moisture conservation methods have been recognised to play an
important role in solving the problem of erosion, siltation of lowlands and retaining the
productivity of soil. Soil moisture and nutrients are critical for better growth. There is need to
diverse suitable techniques of soil moisture conservation and also nutrient management. A
field experiment was carried out at Arekoppa village, Sirsi Taluk of Uttar Kannada district
with a land slope of 5-6% during 2012-2013 on “Influence Of Moisture Conservation
Measures And Nutrient Management On Growth Of Artocarpus heterophyllus In
Terekenhalli Watershed Area” with four main treatments viz., Full moon basin, Half moon
basin, Mulching (Eupatorium @ 5 t/ha), Control and four sub treatments viz., 20:12:6
N:P2O5:K2O kg/ha + FYM (5 t/ha), 10:6:3 N:P2O5:K2O kg/ha + Vermicompost (2.5 t/ha),
10:6:3 N:P2O5:K2O kg/ha + Poultry manure (0.75 t/ha), 30:18:9 N:P2O5:K2O kg/ha + FYM (5
t/ha). Significantly higher plant height was recorded in full moon basin with 30:18:9
N:P2O5:K2O kg/ha + FYM (5 t/ha) at 12 months after treatment (181.70cm). Plant collar
diameter (18.31 mm) and crown diameter (103.41cm) recorded significantly higher in full
moon basin with 30:18:9 N:P2O5:K2O kg/ha + FYM (5 t/ha) at 12 months after treatment.
Number of leaves (48.78) and branches (11.45) recorded significantly higher in full moon
basin with 30:18:9 N:P2O5:K2O kg/ha + FYM (5 t/ha) at 12 months after treatment. Soil
moisture content at 0-30cm (1168 %) and 30-60cm (12.95 %) recorded significantly higher in
treatment receiving full moon basin with 30:18:9 N:P2O5:K2O kg/ha + FYM (5 t/ha) in April
month over the other treatments.
