Bu araştırma, farklı dönemlerde ve dozlarda humik asit uygulamalarının patatesin
verim ve bazı özelliklerine etkilerini belirlemek amacı ile 2018 yılında Ordu ili
Kabadüz ilçesi Yukarıkirazdere mahallesinde yürütülmüştür. Çalışmada materyal
olarak tescilli Jelly patates çeşidi kullanılmıştır. Humik asit uygulaması dikim öncesi
topraktan (0, 4, 8, 12 lt/da) ve çiçeklenme öncesi yapraktan (0, 400 ml/da) olmak üzere
iki farklı dönemde yapılmıştır. Araştırma sonucunda bitki boyunun 97.97-112.93 cm,
ana sap sayısının 6.03-8.03 adet/ocak, ocak başına yumru sayısının 6.13-7.93
adet/ocak, ocak başına yumru veriminin 510.58-693.41 g/ocak, dekara yumru
veriminin 3309.18 – 4127.48 kg/da pazarlanabilir yumru veriminin 2646.82-3752.57
kg/da, büyük yumru oranının %8.53-24.93, orta yumru oranının %62.88-77.81, küçük
yumru oranının %9.68-12.85, kuru madde oranının %17.65-18.54 ve nisaşta oranının
da %13.86-14.46 arasında değişim gösterdiği belirlenmiştir. Bu çalışmada humik
asitin topraktan ve yapraktan birlikte uygulamasının bitki boyu ve ana sap sayısı
üzerine çok önemli, topraktan humik asit uygulamasının ocak başına yumru verimi,
dekara yumru verimi ve pazarlanabilir yumru verimi üzerine önemli etkide bulunduğu,
yapılan uygulamaların diğer özellikler üzerine olan etkilerinin ise istatistiksel olarak
önemsiz olduğu belirlenmiştir.,This study was carried out in order to determine the effects of humic acid applications
on yield and some properties of potato in different periods and doses in 2018 in
Yukarıkirazdere district of Kabadüz, Ordu province. In the study proprietary Jelly
potato was used as a material. Humic acid application was carried out in two different
periods as pre-planting soil (0, 4, 8, 12 lt / da) and before flowering (0, 400 ml / da).
As a result of the research, it was determined that the height of the plant was 97.97 cm
-112.93 cm, the main stem number was 6.03 / hill 8.03 unit / hill, the number of
tubers per hill was 6.13 unit / hill -7.93 units / hill, the tuber yield per hill was 510.58
gr / hill-693.41 g / hill, the tuber yield per decare was 3309.18 kg/da – 4127.48 kg/da,
marketable tuber yield was 2646.82 kg / da-3752.57 kg / da, the rate of big tuber was
8.53- 24.93%, the rate of middle tuber was 62.88 -77.81% and the rate of small tuber
was 9.68 and 12.85%; the rate of dry matter was 17.65-18.54% and the rate of amylum
was between 13.86% and 14.46%. In this study, It was determined that application of
humic acid from soil and leaves was very important on plant height and number of
main stems; application of humic acid from soil had significant effect on tuber yield
per hill, tuber yield per decare, marketable tuber yield and the effects of applications
on other properties were statistically insignificant.
