EFFECT OF SULPHUR AND PHOSPHATE FERTILIZATION ON GROWTH YIELD AND FRUIT QUALITY OF PEPPER (Capsicum annuum, L.) b-Effect on yield, fruit quality and nutrient components
Two field experiments were carried out at El-Baramoon Farm, Mansoura Horticultural Research Station, during the summer seasons of 2002 and 2003.The study aimed to investigate the effect of sulphur levels(0, 150 and 300 kg S /fed.) and phosphorus fertilization levels (0,30, 60 and 90 kg P2O5/fed.) and their interaction on yield components (number of fruits/plant, average fruit weight, fruit yield/plant, early and total yield/ fed.), fruit physical characteristics (fruit length, fruit diameter, fruit shape index, flesh thickness and dry matter %), fruit chemical compositions (TSS, carotenoids, Vit. C, total acidity) and fruit mineral contents i.e. N, P, K, S, Fe, Zn. and Mn of sweet pepper cv. California Wonder. The obtained results showed that all the previous parameters were increased with the increase of sulphur levels from zero up to 300 kg/fed compared with control. The increments were significant except those of number of fruits/ plant in the two seasons, fruit shape index in the second season, flesh thickness in both seasons which showed no significant differences. All tested fruit parameters were significantly increased with the addition of phosphorus compared with control However, the differences among treatments were not significant in each of No. fruits/plant, fruit shape index and flesh thickness in both seasons. Results also declared that the highest contents of Fe, Zn and Mn were noticed with 60 kg P2O5/ fed then decreased with 90 kg P2O5/ fed and the differences in Mn contents were insignificant. The interaction effects showed that the highest level of sulphur (300 kg S/fed) plus the highest phosphorus level (90 kg P2O5 /fed.) had superior effects on all the studied parameters, except that Fe, Zn and Mn contents which gave their highest contents with 300 kg S/fed plus 60 kg P2O5/ fed.
