Pengaruh Interval Waktu Pemberian Air pada Tanah Inceptisol terhadap Pertumbuhan Tanaman Tomat (Solanum lycopersicum)

Abstract

The time interval for giving water to inceptisol soil is a very effective factor for the use of irrigation water so that there is no wastage of water and it is used according to plant needs, The purpose of this study was to determine the time interval of water application on inceptisol soil on the growth of tomato plants (solanum lycopersicum) with several water treatments, this study was in a greenhouse scale using a completely randomized non- factorial design consisting of 4 treatments and 5 replications. namely giving water every day. giving water once for 3 days. giving water once for 5 days. giving water once for 7 days, Parameters observed included soil texture. soil organic matter. bulk density. particle density. porosity. Evapotranspiration. water supply to plants. fruit weight, The results showed that the type of inceptisol soil was sandy loam in texture. soil organic matter was 3.46%. the average soil bulk density 0.95 g/cm3 . the average soil particle density 2.0 g/cm3 . the averge soil porosity 54%. the average soil evapotraspiration 6.6-3.3 mm/day. field capacity water content was an average of 64.1%, water supply to tomato plasts was daily watering an average of 268.37 – 156.57 ml/day. water supply once every 3 days range 663.68 – 387.27 ml. give water once every 5 days range 918.37-726.40 ml. give water once 7 days range 1,324.40- 907.14 ml,
