“…The above correlations indicate that within the studied range of conditions, seedling weight was the predominant factor determining pepper development and yield in the field. This conclusion is in agreement with published data on pepper and tomato transplants behavior under field conditions (Klapwijk and de Lint, 1975;Kooistra, 1978;Skapski and Lipinski, 1978). The next important factor was seedling top N concentration, but this factor cannot be used as a single criterion of seedling quality, as suggested by Knavel {1977).…”

The use of pepper (Capsicum annuum L.) seedlings for transplanting in the field is common. However, very little is known about the effects of root volume and nutrition in the nursery on transplant performance in the field. The objective of this work was to study the effects of N and P supply to various root volumes on pepper seedling development and growth in the nursery, and fruit yield and harvest earliness in the field. Seedlings were grown in trays packed with a peat/vermiculite mixture, 1:1 (v/v). The plants were irrigated by soaking the trays in the studied nutrient solutions. Phosphorus and N concentrations in the test solutions were 0.1, 0.5 and 1.0 mM P and 1, 5, 10 and 15 mM N (NH4/NO3 = 1:1). Root volumes (V) were 5, 15, 35, 65 and 700 cm3 plant−1. Following transplanting, all plants in the field received identical, optimal irrigation and fertilization. Seedling weight increased with increasing root volume and nutrient concentrations in the irrigation water. The optimal solution for pepper seedlings in the studied growth medium was 5 mM N and 0.5 mM P. Nitrogen, P and K contents in tops of optimal seedlings (V = 700 cm3) were 39, 5.5 and 67 g kg−1 dry matter, respectively. Seedling development was retarded when top's content was <25 mg N kg−1 and <3.1 mg P kg−1. Four weeks after transplanting plant weight in the field increased and fruit ripening was hastened when the top's dry weight at planting time increased from 63 to 285 mg plant−1. Plant relative growth rate and total fruit yield were unaffected by nursery treatments.

“…Klapwijk and de Lint (1975) found a correlation between the rate of reproductive development and the increase in fresh weight of the whole shoot under normal glasshouse conditions. Where this is not practicable, time to flower bud visibility may be observed but this necessarily includes some period of post-initiation flower growth.…”

“…Thus Aw in a crop with a full canopy may be as high as 194kgha-1 d-1 and an Rw of 0.6 d-1 has been recorded in young plants in greenhouses in the Netherlands (Klapwijk, 1975b;Klapwijk and de Lint, 1975a). FA is the product of two further useful parameters, the specific leaf area SL = AIWL , and the leaf weight ratio, Fw = WdW, where W L is the total dry weight of the leaves.…”

“…Evidently factors additional to total radiation were affecting the duration of the vegetative phase. Radiation levels may also reach saturation levels for growth of the whole shoot system at this time of year (Klapwijk and de Lint, 1975). Under certain conditions time to opening of the first flower in the first inflorescence may be closely related to total radiation received.…”
