Abstract

 

A field experiment was conducted to evaluate the influence of weeding frequency and pigeon_pea population density on the performance and productivity of maize-pigeon_pea intercropping at Hawassa.  Treatment combinations consisting of two weeding frequency and three pigeon_pea population densities intercropped with maize and sole crops of maize and pigeon_pea were tested in randomized complete block design (RCBD) with three replications. The results indicated that increase in weeding frequency to twice caused 83.6% reduction in weed biomass as compared to weeding only once. On the other hand increasing the pigeon_pea population density to 187,000 and 250,000 plants ha-1 decreased weed biomass by 34.6 and 23.8% respectively. Growth parameters and yield components were also significantly influenced by weeding frequency rather than population density. Pigeon_pealeaf area index and grain yield were significantly affected by all the treatments. Significantly higher grain yield (4.17t/ ha) of maize and (0.80t/ha) of pigeon_pea were obtained from weeding twice. The highest grain yield was obtained from the highest pigeon_pea population density 250,000plants ha-1. Land use efficiency was increased by weeding frequency. The highest total LER (1.26) was obtained from weeding twice. Total LER of 1.24 was recorded from pigeon_pea plant population of 250,000 plants ha-1.

 

Key word: Maize, pigeonpea, LER, weeding frequency, plant density
