Response of Growth, Yield and Quality of Pakchoy (Brassica campestrisL., Chinensis Group) to Zeolit and Organic Fertilizer Application at Ultisol Jatinangor

This research was aimed to investigate the response of growth, yield and quality of pakchoy plant (Brassica campestris L., Chinensis Group) on zeolit and organic fertilizer application at Ultisol Jatinangor, as well as to find out the dosage of zeolit and organic fertilizer giving the best of growth, yield and quality pakchoy plant result gift zeolit and organic fertilizer at Ultisol Jatinangor. This research was done in May 2010 to June 2010, at green house of Agriculture Faculty, Universitas Padjadjaran, Subdistrict Jatinangor – Regency Sumedang with an altitude of about 700 m above sea level (asl) and soil order is ultisol with the type of climate building on fall of rain including C3 based on Oldeman classification. Experimental design used was Randomized Block Design which consists of ten treatments and three replications. The treatments were as follows: without zeolit and organic fertilizer, 0.75 g/polybag zeolit + 15 g/polybag organic fertilizer, 1.5 g/polybag Zeolit + 15 g/polybag organic fertilizer, 2.25 g/polybag Zeolit + 15 g/polybag organic fertilizer, 0.75 g/polybag Zeolit + 30 g/polybag organic fertilizer, 1.5 g/polybag Zeolit + 30 g/polybag organic fertilizer, 2.25 g/polybag Zeolit + 30 g/ organic fertilizer, 0.75 g/polybag Zeolit + 45 g/polybag organic fertilizer, 1.5 g/polybag Zeolit + 45 g/polybag organic fertilizer, 2.25 g/polybag Zeolit +45 g/polybag organic fertilizer. The research showed that zeolit and organic fertilizer application at Ultisol Jatinangor affected growth and yield . The dosage of 2.25 g/polybag Zeolit + 45 g/polybag organic fertilizer gave the better effect on plant height, leaf wide and yield.
