Winter moisture values and possible first irrigation time under different cropping patterns in the Konya plain
Abstract
In this study, the effects of different rotation systems on the storage of winter precipitation in the soil profile in the Konya plain were investigated. Konya plain is a semi-arid region, and a large part of the agricultural lands are left fallow in the parts where irrigation is not possible so that the winter precipitation remains in the next year. In the experiments, moisture observations were made in the fields cultivated with alfalfa, wheat, sugar beet, wheat, and bean plots processed in rotation. As a result of observations and measurements made over four years, in all trials, soil moisture reached its highest level, at the beginning of March, at a soil depth of 120 cm. The effect of sowing patterns on moisture accumulation is insignificant. While the moisture decreases between March and April were found to be statistically significant, it is understood that the moisture loss is mainly in April. As a matter of fact, due to the moisture loss, a significant difference was not found between the soil moisture contents in April and May. Analyzing long-year climate data showed that the dam gates must be opened in April, and water must be given to the plain to prevent product losses due to drought.

Abstract
Bu çalışmada, Konya ovasındaki toprak profilinde kış yağışlarının depolanmasına farklı rotasyon sistemlerinin etkileri araştırılmıştır. Konya ovası yarı kurak bir bölge olup, tarım arazilerinin büyük bir kısmı sulamanın mümkün olmadığı kısımlarda nadasa bırakılarak kış yağışları bir sonraki seneye bırakılmaktadır. Denemelerde yonca, buğday, şeker pancarı, buğday ve münavebe ile işlenen fasulye parselleri ile yetiştirilen tarlalarda nem gözlemleri yapılmıştır. Dört yıl boyunca yapılan gözlem ve ölçümler sonucunda tüm denemelerde toprak nemi en yüksek değerine Mart ayı başında 120 cm toprak derinliğinde ulaşmıştır. Ekim desenlerinin nem birikimi üzerindeki etkisi önemsizdir. Mart-Nisan ayları arasındaki nem düşüşleri istatistiksel olarak önemli bulunurken, nem kaybının ağırlıklı olarak Nisan ayında olduğu anlaşılmaktadır. Nitekim Nisan ve Mayıs aylarında toprak nem içerikleri arasında yüksek nem kaybı nedeniyle önemli bir farklılık bulunmamıştır. Uzun yıllara ait iklim verileri incelendiğinde kuraklıktan kaynaklanan ürün kayıplarını önlemek için baraj kapaklarının Nisan ayında açılması ve ovaya su verilmesi gerektiği ortaya çıkmıştır.
