Abstract:

A  plant  growing  experiment   was  conducted  in  2002-2003  on  the  aubergine cultivars Epic F1 and  Solara  F1 grown  in  an  unheated  polyethylene  tunnel greenhouse  at  the Experimental Station   in  Marcelin, the  University  of Life  Sciences  in  Poznan.   Seedlings  were planted  on May  15 on beds at a 0.5  x 0.5  m spacing,  i.e.  4 plants  m-2, into 6 dm3  cylinders filled  with  a mixture, limed  to pH(H2O)  = 6.5,  of mineral soil  (light  loamy  sand  containing 12%  clay fraction - deposited on medium-heavy  loam)  with  highmoor  peat  from  Lithuania (v:v  = 4:1). Basic fertilization - pre-vegetation  and  top dressing  with  macronutrients, based on an analysis of the substrate using the universal method in 0.03 M CH3COOH, was determined to attain the assumed levels: L (N - 200,  P - 175, K - 330 mg dm-3), S (N - 300, P  - 265, K - 500  mg dm-3), H  (N - 400, P  - 350,  K - 665 mg dm-3),  while maintaining the  N:P:K ratio  at  1:0.9:1.7. The  aim  of this study has  been to determine the  effect  of a  fertilization level  and  cultivar on the  yield and biological  value  of fruits   of aubergine  grown  on a  mixture of mineral   soil with  highmoor  peat (v:v  - 4:1).  The  total yield,  number  of fruits   and  weight  of individual fruits   were  determined.  Significant  effect was  found for  the fertilization level  and  cultivar on the  total  yield,  mean number  of fruits and  weight  of a single  aubergine  fruit.   Fruits of cv.  Epic   F1 aubergine contained  more vitamin C than  fruits  of cv.  Solara  F1. In  both years,  the solids  content in fruits  of the two aubergine  cultivars ranged  from  4.0  to 5.5  %. A  higher  mean  dry  matter content  in  aubergine fruits  was  recorded in  cv. Solara  F1.
