SKRIPSI PENGARUH MACAM MULSA ORGANIK TERHADAP PERTUMBUHAN DAN HASIL BEBERAPA VARIETAS BAWANG MERAH (Allium cepa L)
ABSTRACT
The objectives of this research was to study the influence of kind of organic mulch on growth and yield of shallot (Allium cepa L.) varieties. This research was carried out at Kaliputih village, District Ambarawa, in the Region Semarang, from February 29 until May 5, 1996. The soil type used is Latosol, at the elevation 510 meter above sea level.
The research methode used factorial (3 x 3) experiment in split plot with randomized complete block design consisted of three replications. Kind of organic mulch as sub plots consisted of three level no mulch, chaff and paddy straw combined with kind of varieties as main plots Bima, Kuning and Samas variety.
Results of research indicated that:
1. Samas variety have the highest yield on variables fresh
weight of bulbs per hill 69,00 gram and dry weight of
bulbs per hill 65,26 gram. Kuning variety have the lowest
yield on variables fresh weight of bulbs per hill 38,8
gram and dry weight of bulbs per hill 35,34 gram.
2. The present of organic mulch to increase on diameter of bulb, dry weight of bulbs per hill and dry weight of straw per hill.
3. Paddy straw mulch gives the highest result on diameter of bulb 25,53 mm and dry weight of bulbs per hill 54,47 gram. The lowest yield found on no mulch treatment.
4. The highest mortality percentage found on Kuning variety 27,92% and the lowest mortality percentage found on Samas variety 1,9%.
5. The hypothesis that Bima variety and paddy straw mulch have the highest yield is refused, on the other hand it is Samas variety and paddy straw mulch.
