Soybean Seed Yield as Affected by Time of Sowing in a Cool Temperate Environment

Abstract

Experiments were conducted over two seasons (1999/ 2000 and 2000/2001) at Canterbury, New Zealand (Lat. 43°38ЈS, Long. 172°30ЈE) to study the effect of time of sowing on soybean (Glycine max (L.) Merrill.) seed yield and yield components. Four cool-tolerant cultivars (Northern Conquest (Group V) and Maypole, Alta and March (Group VII)) were sown at three dates (15 November, 7 and 29 December) in 1999 and two of the cultivars (Northern Conquest and March) were sown at four dates (

Effect of Sowing Date on Germination and Vigour of Soybean (Glycine max (L.) Merr) Seeds

“…Thus, the present study confirmed that the crop environment that gives higher seed yield also produces seed lot with high germination and vigour index (Rahman et al, 2004). Variation in seed germination and vigour due to variation in sowing date has also been reported by previous workers (Adam et al, 1989;Rahman et al, 2005;TeKrony et al, 1997). The variation in seed germination and vigour comes from the environmental conditions that the crop experiences during the seed development and maturation (Dornbos, 1995).…”

Effect of Date of Sowing and Foliar Application of Nutrients on Seed Quality of Soybean

“…These results are in accordance with the findings of several other workers (Yari et al, 2013 andRahman et al, 2006), who reported that earlier sowings provided the short vegetative period of growth and comparatively longer reproductive and seed filling period, which significantly raised test weight.…”

Climate Change: Seed Production and Options for Adaptation

“…These include soil temperature effects on germination and emergence [115], day length responses, particularly premature flowering in short days [116], the possibility of frosts during flowering [117], water availability [118], and increased weed, pest, and disease pressure [16,20].…”
