The Effects Of Row Spacing On Yield And Yield Components Of Full Season And Double-Cropped Soybean, Sevgi̇ Çalişkan, Mehmet Arslan, İlhan Üremi̇ş, Mehmet Emi̇n Çalişkan

Compared to full season soybean cropping systems, seed yield reduction is a major concern in double-cropped soybean production systems. This study was conducted at the Research Farm of Mustafa Kemal University, Hatay, Turkey, to determine if it is possible to enhance the yield of both full season and double-cropped soybean by narrowing row spacing. Two soybean cultivars, A3935 and S4240, were planted using row widths of 30, 50, and 70 cm, and twin row (50 25 50 cm) in 2004 and 2005. Seed yield and the other investigated plant parameters of double-cropped soybean were lower compared to full season soybean. …


Estimates Of Broad-Sense Heritability For Seed Yield And Yield Components Of Grass Pea (Lathyrus Sativus L.), Mevlüt Türk, Sebahatti̇n Albayrak, Necmetti̇n Çeli̇k Jan 2007

Estimates Of Broad-Sense Heritability For Seed Yield And Yield Components Of Grass Pea (Lathyrus Sativus L.), Mevlüt Türk, Sebahatti̇n Albayrak, Necmetti̇n Çeli̇k

Turkish Journal of Agriculture and Forestry

This study was carried out to estimate the broad-sense heritability for seed yield and some yield components of 15 grass pea (Lathyrus sativus L.) genotypes in 2000-2002 at Bursa, in the Marmara region of Turkey. The experimental design was a randomized complete block design with 3 replications. The heritabilities for seed yield, plant height, pod number, seed number per pod, seed number per plant, 1000-seed weight, biologic yield, and harvest index were estimated as 30%, 42%, 61%, 19%, 56%, 75%, 82%, and 49%, respectively. It was found that biologic yield was the trait least affected by environment, followed by 1000-seed …

Determining The Relationships Between Yield And Yield Attributes In Sunflower, Yalçin Kaya, Göksel Evci̇, Sezgi̇n Durak, Veli̇ Pekcan, Tahi̇r Gücer

Relationships between seed yield and agronomic characters in sunflower were investigated without considering genetic effects. Sunflower hybrids were evaluated in 3 categories: constant hybrids, control hybrids (mostly the same in each year), and test hybrids (changing each year). Seed yield was positively correlated with oil content, plant height, and 1000-seed weight, but flowering and physiological maturity period correlated negatively with yield based on the analyses in this research. A diverse relationship was determined between the seed yield of the hybrids and oil content. Results of the regression analysis indicated that, up to 40%-45% oil content, there was a negative correlation …
