Intra-Row Spacing and Variety Interaction Effects on the Yield Performance of Sunflower (Helianthus Annuus L.) in Calabar

Effects of inter and intra row spacing on growth, yield and yield components of Roselle (Hibiscus sabdariffa L.)

A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of Roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, WG-Hi...

Effect of Tannery Wastewater on the Growth and Yield of Sunflower (helianthus Annuus L.)

The effects of tanneries wastewater on growth and yield of three cultivars (SF-187, CRN-1435 and DK3915) of sunflower (Helianthus annuus L.) showed that wastewater was not fit for irrigation due to extremely high mineral and heavy metal contents. In addition, effluents were highly alkaline with high load in EC, BOD, COD and SAR values. The amount of iron, manganese, zinc and chromium was also q...

Pinching and Spacing Effects on Cut Sunflower (Helianthus annuus) Production in East Texas

Effect of deficit irrigation on seed yield and yield components of sunflower (Helianthus annuus L.) hybrids

This experiment was conducted to evaluate the effect of deficit irrigation on seed yield and its components of sunflower hybrids, and also identify tolerant hybrids. Twelve sunflower hybrids; Farrokh, Shams, Ghasem, Barzegar, G5 ×43, G6×43, Hysun25, Hysun36, Azargol, Sumbro, Euroflor and Sirena were evaluated under three irrigation treatments; normal irrigation (60 mm), mild drought stress (1...
