    Studies on effect of in-situ moisture conservation measures and organic manures on growth of simarouba glauca in varada watershed area
    (UASD) Manikhantha M. Vaidya; Gopal V. Dasar
    Soil and water conservation measures are one of the most important factors for the improvement of degraded lands. Water conservation technique like in-situ soil moisture conservation measures and application of organic manures is to achieve the maximum cultivated soil for the survival and growth of seedlings. A field experiment was carried out at Karjagi village, Haveri Taluk of Haveri district with a land slope of 3-4 per cent during 2012-2013 on “Studies On Effect Of In-Situ Moisture Conservation Measures and Organic Manures On Growth Of Simarouba glauca In Varada Watershed Area” with four main treatments viz., Conservation pit, Ring basin, Half ring basin, Control and four sub treatments with organic manures viz., Farm yard manure (5 t/ha), Vermicompost (2.5 t/ha), Poultry manure (0.75 t/ha) and Control. Significantly higher plant height was recorded in ring basin with Vermicompost (2.5 t/ha) at 12 months after treatment (1.94 m). Plant collar diameter (3.97 cm), crown diameter (133.83 cm) and number of leaves (63.07) recorded significantly higher in ring basin with Vermicompost (2.5 t/ha) at 12 months after treatment. Soil moisture content at 0-30 cm (7.77 %) and 30-60 cm (13.07%) recorded significantly higher in the treatment receiving ring basin with Vermicompost (2.5 t/ha) at 10th month over the other treatments. In combination of Ring basin with Vermicompost (2.5 t/ha) had recorded significantly higher on organic carbon (1.01%), higher available nitrogen (277.13 kg/ha), phosphorus (27.81 Kg/ha) and potassium (170.54 kg/ha) over the other treatments.
