Abstract

Crop production is of major supports for ever-growing population. As for other crops, wheat cannot escape from weed interference which may result in significant loss of yield. Therefore, the success of agricultural practices depends on pest and diseases management including weeds. Agricultural chemicals such as herbicides has been widely applied to maximize crop yield including wheat. The present study was conducted to determine the appropriate herbicide to control weeds associated with wheat and wheat growth and yield. The experiment was carried out at farmer’s land at Batu Bagiriek, Jorong Galagah, Kenagarian Alahan Panjang, Solok, the Province of West Sumatra from May to September 2015. The experimental sites is located at 1.0729° S, 100.7831° E, 1616 m above sea level with temperature ranging from 20 to 25 °C. Three treatments i.e herbicide metsulfuron-methyl (25 g ai ha-1), herbicide 2,4 dimethylamine (1.5 L ai ha-1), and no weed control treatment were studied. Each treatment was replicated four times in a completely randomized design. Data were analysed with ANOVA and mean separation of Tukey HSD at 5%. Results demonstrate that herbicide 2,4 dimethylamine was best to control broad leaf weeds resulted in the highest yield of wheat grain of 6.14 tonnes/ha. Lawn grass (Axonopus compressus) and goose grass (Eleusine indica) were found to be dominant weeds.

Highlights

Wheat (Triticum aestivum L.) is of world major cereal crops and is a non-tropical origin
USDA projected that Indonesia, in 2016, will import wheat as much as 7.6 million metric tonnes (MMT) and this has increased for 1.6% from last year [1]
One-half of the dose of Urea was applied at seven days after planting (DAP) and the rest was applied at 30 DAP

Summary

Introduction

Wheat (Triticum aestivum L.) is of world major cereal crops and is a non-tropical origin. Weeds reduce agricultural crop growth and yield trough resource competition and/or allelopathy. Research reported here dealt with weed associated with wheat in response to herbicide application as well as wheat growth and yield. Wheat growth was observed and data collection included number of days to panicle emergence, number of panicles, seed weight, and yield.
