ABSTRACT Adjustment of planting geometry along with reduced applications of herbicides can be a viable tool for effective weed management in rice. This present study has examined the effects of three planting geometries (20 cm x 20 cm, 20 cm x 10 cm and 10 cm x 10 cm); along with early post emergence herbicides, viz; bispyribac sodium 20% WP at 39.50 g a.i. ha-1, bispyribac sodium 100 SC at 39.50 g a.i. ha-1, cyhalofop-butyle 10% EC at 49.50 g a.i. ha-1, and penoxulam 240 EC at 15 g a.i. ha-1 on weed growth, and rice performance under semi-arid climate. A weedy check was maintained as control where no herbicide was applied. Results showed that the narrowest plant spacing (10 cm x 10 cm) effectively controlled weeds; however, it also resulted in reduced... |

The research studies an arthropod community in upland rice ecosystem at farmers’ field in Ban Had District, Khon Kaen Province, Northeast Thailand, was conducted during May to October 2011. Samples were collected using light traps, yellow sticky traps, sweep nets and visual observation methods. A total of 7,195 individual arthropods from 160 species were recorded in this study. Among the sampling methods, 140 species were recorded using light trap, followed by 108, 58 and 30 species collected by using yellow sticky trap, sweep net and visual observation, respectively. The arthropod community of this studies constituted of four guilds as phytophagous, predator, parasitoid and scavenger. The predator (60.93 % of total individuals and 47.17% of total species)... |
