Abstract

A field experiment was conducted at Wondo Genet Agricultural Research Center under irrigated conditions during 2018, to evaluate the performance of tomato yield and yield components under an intercropping system with different basil planting densities and row arrangements. it was arranged in a 2 × 4 factorial arrangement in randomized complete block design with three replications each consisting of ten treatments: two basil row arrangements (one tomato row alternating with one basil row (1T:1B) or with two basil rows (1T:2B)) and four basil population densities (66666, 50000, 33333 and 16666 plants ha -1). Results of the study indicated that intercropping system significantly (p<0.05) affected the yield and yield components of tomato. Inter-cropped tomato with basil had the highest yield (36657.8 kg ha-1) as compared to sole cropped tomato (31004.3kg ha-1) and inter-cropping with basil increased its yield by 15.42%. Therefore, basil with a density of 33,333 plants ha-1and intercropped with tomato with 1T:1B row arrangement could be recommended for the wondo genet and similar agroecology area. However, the effect of tomato-basil intercropping on the incidence and severity of major tomato insects and diseases needs further study.

优化番茄-罗勒间作系统中罗勒（Ocimum basilicum L.）的种植密度和行列安排

2018 年，在 Wondo Genet 农业研究中心进行了一项灌溉条件下的田间试验，以评估不同罗勒种植密度和行间排列的间作系统下番茄产量和产量成分的表现。研究采用 2 × 4 因式排列的随机完全区组设计，每组有三次重复，包括 10 个处理：两种罗勒行排列（一种番茄行与一种罗勒行（1T:1B）或两种罗勒行（1T:2B）交替排列）和四种罗勒种植密度（66666、50000、33333 和 16666 株公顷-1）。研究结果表明，间作系统对番茄的产量和产量成分有显著影响（p<0.05）。与单作番茄（31004.3 千克/公顷-1）相比，与罗勒间作番茄的产量最高（36657.8 千克/公顷-1），与罗勒间作番茄的产量提高了 15.42%。因此，在 wondo genet 和类似的农业生态区域，罗勒的种植密度为 33333 株/公顷，并与番茄间作，行间排列为 1T:1B。不过，番茄-罗勒间作对番茄主要病虫害发生率和严重程度的影响还需要进一步研究。
