THE EFFECT OF TWIN ROW PLANTING PATTERN AND PLANT POPULATION ON YIELD AND YIELD COMPONENTS OF PEANUT (Arachis hypogaea L.) AT MAIN CROP PLANTING IN CUKUROVA REGION OF TURKEY

This study was conducted at the Cukurova University research farm as a main crop in 2013 and 2014 in Adana, Turkey. The objective of this study was to determine the effect of twin row planting pattern and plant densities on yield and yield components of peanut. The experimental design was a Randomized Complete Block Design with three replications. The Halisbey (Virginia type) variety was used as a plant material in this research. The planting pattern was used as twin-row and conventional single-row. The row spacing was 70 x 25 x 70 cm, 75 x 25 x 75 cm and 80 x 25 x 80 cm for twin-row planting pattern and 70 cm for single-row pattern. Intra-row spacing of 10, 15 and 20 cm was arranged for different plants population. According to a two-year average, the highest pods yield (7833.6 kg ha-1) was obtained from 70 x 25 x 70 x 10 cm (21.05 plants m-1) twin-row planting pattern while the yield was 6688.8 kg ha-1 in single-row planting pattern as 70 x 15 cm (9.43 plants m-1). The yield increase was 17.86% in 70x25x70x10, 16.70% in 75x25x75x10 and 15.79% in 80x25x80x10 twin-row pattern, compared with traditional single-row planting pattern.

İkinci Ürün Koşullarında Yetiştirilen Bazı Soya Çeşitlerinin Önemli Agronomik ve Kalite Özelliklerinin Belirlenmesi

Ikinci urun kosullarinda yetistirilen bazi soya cesitlerinin onemli agronomik ve kalite ozelliklerini belirlemek amaciyla yapilan bu calismada, farkli olgunlasma gurubuna giren 14 farkli soya cesidi (Nova, May 53-12, Ilksoy, Arisoy, Atakisi, Atem-7, Umut-2002, Cinsoy, Sa.88, S.4240, Turksoy, Adasoy, Blaze ve Ha.16-21) materyal olarak kullanilmistir. Arastirmaya konu olan denemeler 2013 ve 2014 yillarinda, C.U. Ziraat Fakultesi, Tarla Bitkileri Bolumune ait arastirma alaninda kurulmus ve yurutulmustur. Denemeler tesaduf bloklari deneme desenine gore uc tekrarlamali olarak kurulmustur. Denemeye alinan cesitlerin; bitki boyu, ilk bakla yuksekligi, bakla sayisi, dal sayisi, 100 tohum agirligi, yag orani, protein orani ve tohum verimi gibi onemli agronomik ve kalite ozellikleri incelenmistir. Iki yillik sonuclara gore denemeye alinan soya cesitlerinin tohum verimi degerleri 321-463 kg/da arasinda degisim gostermistir. Dekara tohum verimi bakimindan ilk sirayi; Arisoy (466.7 kg/da) ve Atakis (466.2 kg/da) cesitleri almistir. Iki yillik ortalama degerlere gore; cesitlerin yag oranlari %17.11-19.37, protein oranlari ise %36.52-38.46 arasinda degisim gostermistir.
