SKRIPSI PENGARUH PEMBERIAN HYDRASIL DAN SELANG PEMBERIAN AIR TERHADAP HASIL KENTANG (Solanum tuberosum) DI DATARAN SEDANG
ABSTRACT
The experiment for to know the effect of to give hydrasil and interval of irrigation on the yield of potato (Solanum tuberosum) in middle land, had carried out at can, Impel, Boyolali, Central Java, An elevation 700 m above sea level, the soil type brown latosol, soil pH 6. Was carried out during in October 1988 until January 1989.
This experiment used Split Plot Design, the arranges to Randomized Block Design with two treatment and three aplication.
The first factor was interval of irrigation as the main plot, consist of three level; S1: 3 days interval; S2: 6 days interval; S: 9 days interval.
The second factor was concentration of hydrasil as the sub plot, consist of four level; K0: 0 cc/liter of water, K1: 0,5 cc/liter of water; K2: 1,5 cc/liter of water; K3: 2,5 cc/liter of water.
The concentration of hydrasil gave non significant effect on the all parameter, and the interval of irrigation gave significant effect on the several parameter, The average highest of yield be reached of the treatment interval of irrigation days, there were 5.48 1 (the average of the number of tubers/plant), 181.0l gram (the average of weight of dry tubers/plant).
