DETERMİNİNG THE FORAGE YİELD AND CERTAİN CHARACTERİSTİCS OF SOYBEAN (Glycine Max. L) VARİTİES WİTH DİFFERENT SOWİNG DATES

This

research was conducted at Gumushane University, in the field of application of

Gumushane University Vocational School of Higher Education during 2014-2015. The research was carried out in 3 replications according

to the exact blocks trial pattern of chance during the season of breeding

between 2014 and 2015. İn the research Nova, Arısoy,

A-3127, Sa-88, Ataem-7, Bravo, Yeşilsoy and Yemsoy varieties were used, and

different three sowing dates (1 April,15 April, 30 April).<o:p></o:p>

According

to the results, the highest values in terms of green grass and ADF values were

given by Yeşilsoy cultivar. Yeşilsoy cultivar took the first place with 12123.3

kg / ha-1 in terms of green grass yield. In terms of hay yield,

Arısoy cultivar gave the highest value with 5003 kg / ha-1. The

highest values in ADF, NDF and Crude protein content were Bravo 37.51%, Ataem-7

37.48%, Bravo 46.72%, Yeşilsoy 46.48%, Bravo 13.96%, Ataem-7 13%, 95

respectively gave the highest values. In terms of sowing time, sowing time of 1

April gave the highest results among the parameters examined. Therefore, while

sowing time on April 1 was determined as the most suitable planting, Nova,

Arısoy, Ataem-7, Yeşilsoy and Yemsoy varieties were the prominent varieties in

terms of green, dry grass and crude protein.<o:p></o:p>
