Effect of Nursery Period and Block Size on Growth and Yield of Paprika

This study was carried out to investigate the effect of nursery period and block size on seedling quality and fruit yield of paprika (Capsicum annuum L. 'Cupra'). Seeds of paprika (Capsicum annuum L., Cupra) were sown in rockwool plugs. Seedlings were transferred and grown to the rockwool block different sizes: $5{\times}5$, $7.5{\times}7.5$ and $10{\times}10cm$ at sowing after 15 days. The plants were transplanted by 25, 30, 35, 40, 45 and 50 days we planted the seeds to the rockwool slabs. Seedling growth was not influenced by block size in the 25 day old plant, since then growed poorly with increasing nursery period in the $5{\times}5cm$ block size, plant height, stem diameter, fresh weight, dry weight have no difference from $10{\times}10cm$ and $7.5{\times}7.5cm$, but leaves and leaf area were higher $10{\times}10cm$ than the $7.5{\times}7.5cm$ block size. Growth of the paprika in field 80 days after sawing did not differ from nursery period and block size below 35 days old, but decreased with increasing nursery period and decreasing block size beyond 40 days old. Flowering did not differ from nursery period and block size below 35 days, but delayed with increasing nursery period and decreasing block size beyond 40 days old. The highest yield was obtained from 30 and 35 days old, and decreased with increasing nursery period and decreasing block size beyond 40 days old.

파프리카 육묘기간 및 육묘블록의 크기가 생육과 수량에 미치는 영향

파프리카 공정육묘시 육묘일수와 적정 육묘소요면적의 관계를 구명하기 위하여 육묘블록의 크기를 $5{\times}5cm$, $7.5{\times}7.5cm$, $10{\times}10cm$로 달리 하여 25, 30, 35, 40, 45, 50일간 육묘하는 시험처리를 하였다. 묘소질은 25일 육묘시에는 육묘블록의 크기에 따른 차이가 없었으나 육묘기간이 길어지면 $5{\times}5cm$ 블록처리에서 나빠졌다. $7.5{\times}7.5cm$와 $10{\times}10cm$간에는 엽수와 엽면적을 제외한 생육은 차이가 없었다. 정식이후 생육은 정식 후 35일까지는 육묘기간이나 블록크기간의 차이가 없었으나 육묘기간이 길어지고, 육묘블록의 크기가 작을수록 나빠졌다. 개화시기도 35일 육묘처리까지는 처리간 차이가 거의 없었으나 이후 육묘기기간이 길어지고 육묘블록의 크기가 작을수록 개화가 지연되었다. 수량은 30일과 35일 육묘구가 가장 많았고, 40일 이상 육묘할 경우 육묘기간이 길고 육묘블록의 크기가 작을수록 생산량이 감소하였다.
