The Effect of Different Harvest Aiding Chemicals on Yield and Yield Components of Cotton (Gossypium Hirsutum L.)

Abstract

The effect of different harvest aiding chemicals on yield and yield components of cotton (Gossypium hirsutum L.

Effect of Sowing Time in Cotton (Gossypium Hirsutum L.) on Boll Distribution, Cellulose Ratio and Fiber Quality

“…Özkan and Kaynak (2009) obtained the highest yields between 1-6 fruiting branches, which is compatible with our findings. In contrast to our study, the highest fiber yield per plant was reported between 4-9 fruiting branches by Jenkins et al (1990a), between 3-7 fruiting branches by Hake et al (1996), between 6-10 fruiting branches by Beyyavaş and Haliloğlu (2019). The effect of Sowing Date * Cultivars and Sowing Date * Boll Position interactions on fiber yield per plant was not significant, while other interactions were significant (P<0.01).…”

“…Zhao et al (2012) stated that the highest boll weight was recorded in the low positional sympodial branch (1-5 fruit branches) position, while Haliloğlu (1999) found that the boll weight per plant was higher in the uppermost part of the fruiting branches (11th-15th fruit branch). In contrast, Beyyavaş and Haliloğlu (2019) indicated that the position does not have a significant effect on boll weight.…”

“…The boll positions of 10 randomly selected plants from each plot were divided into 3 parts as lower boll positions (1-5 fruit branches), middle boll positions (6-10 fruit branches), and upper boll positions (11 and above fruit branches). The measurements were carried out on the bolls obtained in each position (Beyyavaş and Haliloğlu, 2019). The bolls obtained from each position were counted and weighted, and fiber yields were calculated by ginning.…”

The effect on yield and yield components of different harvest aid chemical applications in normal and late sowing cotton (Gossypium hirsutum L.)

“…Ming-wei ve ark. ( 2013) tüm uygulamaların kontrol parsellerinden daha fazla koza açılmasına katkıda bulunduğunu; Beyyavaş (2019), hasada yardımcı kimyasal uygulamaların kontrole göre daha fazla açan koza oluşturduğunu belirtmeleri; Raghavendra ve Reddy (2020), yaprak dökücü uygulamadan 7 gün sonra, Dropp ultra 250 ml ha -1 'da (%92.3), Dropp ultra 200 ml ha -1 'da (%90.0) ve Ethrel 300 ml ha -1 (%89.0) oranında artış olduğunu belirtmesi çalışmamızla uyum içerisindedir.…”
