Influence of plant population on fruit and seed yield characters of cayenne pepper (<i>Capsicum frutescens L.) genotypes

Abstract

This study assessed the influence of three plant populations (18518, 27777 and 40000 plants ha -1 ) on fruit and seed yield characters in 16 genotypes of Capsicum frutescens in 2010 and 2011 cropping years using a 3 x 16 split plot arrangement fitted into a randomized complete block design. Plant population and genotype formed main and sub-plots, respectively. Data collected on fruit and seed yield characters were subjected to analysis of variance after which means were separated using Fisher's Least Significant Difference. Correlation analysis was also carried out among the characters. Significant and highest (P < 0.01) number of fruits per plant, single fruit weight, fruit weight per plant, number of seeds per fruit, 100 seed weight, seed weight per plant and seed weight per fruit were obtained under 18518 plants ha -1 while highest (P < 0.05) fruit yield ha -1 (11.3 tons) and seed yield ha -1 (698.7 kg) were obtained under 40000 plants ha -1 . Top fruit and seed yielding genotypes across the three plant population were PP9955-15 and Chilli 14, respectively. Number of fruits per plant showed negative and highly significant correlation with single fruit weight, fruit length, fruit width, number of seeds per fruit, 100-seed weight and seed weight per fruit. Significant positive or negative correlations were also observed among other characters. Plant population of 40,000 ha -1 using 50 x 50 cm spacing is recommended for high fruit and seed yield in C. frutescens production.

Characterization and Evaluation of Salvia hispanica L. and Salvia columbariae Benth. Varieties for Their Cultivation in Southwestern Germany

“…Reported manually obtained seed yields and amounts of seeds produced per single plant were in the range of 6.3 to 6.4 g and 4051 to 4289 for Salvia hispanica L., respectively, being distinctly higher compared to the values obtained by the present study [22]. It is, in general, stated that obtained seed yields per single plant and seeds produced per single plant in different plant species could be influenced by various factors, such as plant density, genotypic differences, climatic conditions, and mineral nitrogen content [44][45][46][47]. Reported manually obtained seed yields and amounts of seeds produced per single plant were in the range of 6.3 to 6.4 g and 4051 to 4289 for Salvia hispanica L., respectively, being distinctly higher compared to the values obtained by the present study [22].…”
