Abstract

The spectral reflection characteristics of the plants vary during the vegetation period with the effect of plant nutrient concentrations and other factors. The aim of this study was to investigate the relationship between nutrient concentration and spectral reflection (RF) in the maturity and harvest periods of the rocket (Eruca sativa L.) plant. The study was conducted using a completely randomized block design with three replications under controlled greenhouse conditions. The treatments were solid fertilizers applied before planting at two different rates (0, 300 and 600 kg da-1), and liquid organic fertilizer applied by drip (20-40 lt da-1) throughout the growing period. Within this period, spectroradiometric measurements were taken with a hand spectroradiometer (plant probe and leaf clips) in the range of 330-1075 nm wavelength of the electromagnetic spectrum. In the study, leaf samples were taken simultaneously with spectroradiometric measurements and plant nutrient analyzes were performed in these samples. According to the results, at the maturity stage; between blue band and Cu (0.621**), red band and potassium K (0.554**), harvest stage; green band and P (0.559**), red band and C (-0.581**) there was a statistically significant relationship at P≤0.01 level. With these results, fast, economical and reliable results were obtained in the estimation of some important plant nutrient concentrations affecting yield and quality in rocket cultivation especially in winter in greenhouse conditions without damaging the plant.

Özet

Bitkilerin spektral yansıma karakteristikleri bitki besin maddesi konsantrasyonları ve diğer faktörlerin etkisi ile vejetasyon periyodu boyunca farklılık göstermektedir. Bu çalışmanın amacı, roka (Eruca sativa L.) bitkisinin olgunluk ve hasat dönemlerinde spektral yansıması (RF) ile besin maddesi konsantrasyonu arasındaki ilişkiyi incelemektir. Çalışma kontrollü sera ortamında tesadüf parselleri deneme desenine göre yürütülmüştür. Denemede bitki yetişme periyodu süresince roka bitkisinin bitki besin maddesi konsantrasyonunda varyasyon oluşturmak amacıyla tabandan katı organik gübre (0, 300 ve 600 kg da-1) ve damlamadan sıvı organik gübre (20 ve 40 lt da-1) uygulanmıştır. Ayrıca olgunluk ve hasat dönemlerinde elektromanyetik spektrumun (EMS) 330-1075 nm dalga boyu aralığında el spektroradyometresi ile bitki probu kullanılarak spektroradyometrik ölçümler gerçekleştirilmiştir. Aynı zamanda spektral yansıma alınan yaprak örneklerinde bitki besin elementi konsantrasyonlarını belirlemek amacıyla kimyasal analizler yapılmıştır. Araştırma sonuçlarına göre, roka bitkisinin olgunluk döneminde; EMS’un mavi bandı ile bakır (Cu) (0.621**), kırmızı bandı ile potasyum (K) (0.554**) hasat döneminde ise; yeşil bandı ile fosfor (P) (0.559**), kırmızı bandı ile kalsiyum (Ca) (-0.581**) arasında P≤0.01 seviyesinde istatistiksel olarak önemli ilişkiler bulunmuştur. Araştırma sonuçları, roka bitkisinin bitki besin maddesi konsantrasyonun tahmin edilmesinde olgunluk dönemine göre hasat döneminde daha yüksek korelasyon olduğunu göstermiştir. Bu sonuçlar ile birlikte özelikle kışın sera koşullarında roka yetiştiriciliğinde verimi ve kaliteyi etkileyen bazı önemli bitki besin elementi konsantrasyonlarının tahmin edilmesinde bitkiye zarar vermeden hızlı, ekonomik ve güvenilir sonuçlar elde edilmiştir.
