APLIKASI TEKNIK IRIGASI TETES DAN KOMPOSISI MEDIA TANAM PADA SELADA (Lactuca sativa)

Edit
ABSTRACT: The  effort  to  develop  artificial  planting  media  and  technique  for  more  practical irrigation in the cities growing since the area of land available for farming is getting less. A glass house experiment was run to compare the performance of three types of planting media, i.e. 100% rice husk charcoal (RHC), a mixture of RHC (50%) and andosol (50%) and 100% andosol, which was watered in periodical (once a day, once in two days and once in three days respectively) by means of drip irrigation technique. A weekly observation were made on plant growth parameters (plant height, number of leaves, wide, length and the area  of  leaves)  and  the  shoot  length.  A  daily  observation  was  performed  for  the  room temperature  (in  the  morning,  noon  and  afternoon)  and  amount  of  water  needed  for irrigation.  The  plant  was  harvested  after  31  days  and  the  yield  was  determined  by gravimetry method for fresh vegetable and in a dry form.  The result showed that the use of a mixture between RHC (50%) and 50% andosol watered once ion two days gave the best plant growth and production yield.
