Performance of Teak under Different Irrigation and Fertilizer Management Practices

To find out the effects of irrigation and fertilizer practices on growth of Teak, study was initiated at Hyderabad on sandy loam soils.After a period of 30 months after Teak planting the results revealed that irrigation practices of giving water at 10, 20 and 30 days intervals significantly influenced both the height and girth of Teak trees. Irrigation at 10 days (I₁) and 20 days (I₂) intervals resulted in superior taller trees with greater girth during all periods of study, as compared to irrigation at 30 days interval, (I₁) and no irrigation (I₀. The three years old Teak trees were 4.02 m taller and 28.5 cm thicker in I₃ which was on par with I₂ (4.66 m and 28.04 cm). Though the application of urea did not effect the height and girth of Teak trees during all perinds of study but higher doses of urea application i.e., 200 g (N₂) and 300 g/plant (N₃) caused marginal increase in the growth of Teak. The interaction between irrigation and urea application too, was found insignificant. The greater incremental growth both in height and girth during the period (from 12 months to 30 months after planting) was markedly observed with frequent irrigations but not with nitrogen doses.
