SKRIPSI PENGARUH DOSIS PUPUK N DAN UMUR BIBIT TERHADAP HASIL TANAMAN SELADA ( Lactuca sativa L Var. Great lake)
SUMMARY
The effect of Nitrogen fertiliser dosis and the Age of Seedling on the yield of lettuce (Lactuca sativa L.) Great Leads Varity..
The research wits carried out at Kopeng Getusan area Bluce 25 June up to September 28, 1989. The type of soil in Andosol at an altitude of 1450 metera above sea level..
Taia research nas been conducted to uvaluate the effect of Hitrogen fertiliser and the age of seedling on the yield of lettuce.
The method of research was factorial method with completely random design (BAAL) which consist of two factore each combination was repeated taree time.
The first factor No Bitrogen fertiliser with consist of four Lavels. Nitrogen fertiliser with dusie o kg hu
Nitrogen fertiliser with dosis 110 kg ha
2 Hitrogen fertiliser with dosis 220 kg Mitrogen fertiliser wita doale 330
Second factur
The age of seedling (a) consist of taree
Loveis. Seedling of lettuce piant 25 day T
2 Seedling of lettuce plant 30 daya seedling of lettuce plant 35 days
so we cun get 12 type treatment combinatione The conclation an follow
