Yield trial of 8 karen type chilli varieties grown under two cultivated

Abstract

A yield trial of 8 Karen type chilli varieties in 2 cultivated systems was studied under intercropping with corn and monocropping. Row spacing and tree spacing was 0.4 m x 0.8 m. for single-row. In paired-row used row and tree spacing was 0.4 m. x 0.6 m. From June 2011 to May 2012 at the Agricultural Technology Research Institute, Lampang Province. Data of plant growth and yield were also collected. Results plant growth of the single-row intercropping gave average of plant height 57.2cm. Plant width of paired-row averaged 59.1 cm. Yield of the single-row of the ‘Khiri rat 4’ and ‘Khiri rat 7’ gave 0.37 and 0.36 ton per rai, respectively. Paired–row of ‘Khiri rat 3’ and ‘Khiri rat 5’ were yielded 0.70 and 0.66 ton per rai. Monocropping of ‘Khiri rat 8’ gave 0.34 ton per rai of fresh yield. In addition yield was significantly different statistically among varieties Paried-row was the highest fresh yield of the systems.
