Abstract

Soybean is an important crop in hot sub-moist agro-ecological zone of western Ethiopia. However, the yield of the crop is limited due to lack of recommendation on appropriate plant density for the varieties. Therefore, the experiment was conducted to determine the effect of inter and intra row spacing on growth, yield components and yield of soybean varieties in Dale Sedi District, western Ethiopia. Four inter row spacing (30, 40, 50 and 60cm) and two intra row spacing (5 and 10 cm) were evaluated on three soybean varieties (Nyala, Wello and Dhidhessa). The experimental design was randomized complete block design with three replications. Variety Nyala was earlier in attaining flowering (57.06 days), maturity (101.4days) and gave higher hundred grain weight (23.22g) than varieties Wello and Dhidhessa. The longest plant height (98.61cm), (82.19cm) and (80.14cm) were for variety Wello, from 30cm inter row and from 5cm intra row spacing, respectively. The interaction effect of variety and inter row spacing was highly significant on number of primary branches per plant, number of pods per plant and harvest index. The highest number of primary branches per plant (4.57) and number of pods per plant (65.6) was recorded from variety Wello at 60cm while the highest harvest index (43.6%) was recorded from variety Nyala at 40cm.The interaction effect of the variety and intra row spacing was highly significant on number of effective nodules and number of primary branches per plant, number of pods per plant and above ground biomass. The highest effective nodules (23.1) were recorded from variety Wello at 10cm, the highest number of primary branches (4.78) were recorded from variety Didhessa at 10cm intra row spacing, the highest number of pods per plant (61.49) was recorded from variety Wello at 10cm and the highest above ground biomass (12681kg ha-1) was recorded from variety Wello at 5cm. The three way interaction of variety, inter and intra row spacing was highly significant on crop stand count percentage and total grain yield, where the highest crop stand count at harvest (99.77%) was from variety Nyala at 50cm inter row spacing and 5cm intra row spacing and the highest grain yield was recorded from variety Nyala (4127kg ha-1) at 30cm×10cm, (3523kg ha-1) and (2994kg ha-1) from Wello and Didhessa at 40cm×10cm respectively. Therefore, 30cm×10cm is the best spacing in for high yielding of Nyala variety and 40cm×10cm is the most preferable spacing for the highest yield for Wello and Didhessa varieties.
