Seed borne fungi of Chilli Pepper (Capsicum frutescens) from pepper producing areas of Benue State, Nigeria

The Abundance and Diversity of Thrips (Thysanoptera: Thripidae) on Chili (Capsicum annuum L.) and Cayenne (Capsicum frutescens L.) in Bogor. This research aimed to study the abundance and diversity of thrips on chili pepper and cayenne pepper plants. Observation of thrips was conducted on chili pepper and cayenne pepper in fourteen sites in four different locations in Bogor that are: Dramaga, Cibungbulang, Tenjolaya, and Cisarua. Thrips were collected from leaves and flowers from 10 plant samples that had been selected randomly. The thrips were identified and the number of thrips were calculated. The abundance of adults, nymphs, and total of thrips on the flowers of chili pepper was 0.39, 0.01, and 0.40 thrips/flower respectively. Meanwhile, the abundance of adults, nymphs, and total of thrips on the flowers of cayenne pepper was 0.36, 0.02, and 0.38 thrips/flower respectively. The abundance of adults, nymphs, and total of thrips on the leaves of chili pepper was 0.68, 0.12, and 0.81 thrips/twiq respectively. Meanwhile, the abundance of adults, nymphs, and total of thrips on the leaves of cayenne pepper was 0.47, 0.14, and 0.61 thrips/twiq respectively. Four species of thrips were found infesting flowers of chili pepper and cayenne pepper i. e. Thrips parvispinus, T. hawaiiensis, Scirtothrips dorsalis, and Haplothrips gowdeyi. Species of T. parvispinus, T. hawaiiensis, S. dorsalis belong to suborder of Terebrantia family Thripidae, meanwhile H. gowdeyi belongs to suborder Tubulifera family Phlaeothripidae. T. parvispinus is the most dominant species found infesting flowers and leaves of the chilli pepper and cayenne pepper were 71% and 56 %.

Production Factors

Cayenne pepper is a horticultural crop, which is attracted by consumers. In Kotawaringun Barat Regency in the last 3 (three) years of chilli, production continues to increase, but it is not yet known whether the cultivation is technical, price or economically. The purpose of this research is to know the level of elasticity of production factors to the production of chilli pepper and know the level of technical efficiency, price, and economic farming chilli pepper in West Kotawarwant district. The research was conducted in Kotawaringin Barat District in December 2019 to February 2020. The number of samples used is 100 farmers respondent, with simple random sampling method. Data used by primary data and secondary data. Methods of data analysis using descriptive analysis, analysis of the Cobb-Douglass production function and analysis of technical efficiency, price/allocative, and economic. The results showed that the value of elasticity of the land area (0.501), seedlings (-0.201), fertilizer (0.112) and labour (0.386). The amount of elasticity 0.798 less than one indicates that chilli pepper farming is on a business scale (Decreasing return to scale), which contains the meaning of farming chilli pepper is not in the condition of a constant scale result. The value of technical efficiency (0.199), the value of the efficiency of the price/Alokatif (0.0031), the value of economic efficiency (0.0022), the third value of efficiency less than 1, meaning farming chilli pepper inefficient so that the need to reduce the use of production factors.
