CİPS ENDÜSTRİSİ ATIKSULARININ NOHUT (Cicer arietinum L.) BİTKİSİNİN ERKEN GELİŞİMİ ÜZERİNDEKİ ETKİLERİ

Abstract

Bu çalışma, yüksek organik yük içeren cips atıksularının elektrokoagülasyon (EK) ile arıtımını ve sürdürülebilir tarımda kullanım potansiyelini incelemektedir. EK performansı su kalite parametreleriyle izlenmiş; biyolojik uygunluk nohut (Cicer arietinum L., cv. Azkan) tohumlarında çimlenme ve erken fide gelişimi ile değerlendirilmiştir. EK deneyleri, ham pH (4,65) ve 50 A/m² ile, ayarlanmış pH (6,5 ve 8,5) ve 100 A/m² koşullarında 15–120 dakika uygulanmıştır. En yüksek arıtım 100 A/m² ve pH 6,5’te gerçekleşmiş; 120. dakika sonunda kimyasal oksijen ihtiyacı ve renk giderim verimleri sırasıyla %36,63 ve %97,37 olarak belirlenmiştir. Bitki denemelerinde ham atıksu (HA) ve EK ile arıtılmış suyun farklı seyreltmeleri (%25, %50, %75 ve %100) saf su kontrolü ile karşılaştırılmıştır. Veriler Python ile iki yönlü varyans ve LSD testi (p<0,05) ile analiz edilmiştir. HA-100 ve EK-100 uygulamaları plumula ve radikula büyümesini baskıladı. En yüksek çimlenme EK-25 (%95,45), en uzun radikula (22 mm) ve en yüksek taze biyokütle (6,80 g) HA-50’de gözlendi. Bulgular, düşük seyreltmede olası hormesis etkisini ve EK-25’in çimlenme, HA-50’nin fide ve biyokütle için uygun strateji olduğunu ortaya koymaktadır.

EFFECTS OF CHIP INDUSTRY WASTEWATER ON THE EARLY DEVELOPMENT OF CHICKPEA (Cicer arietinum L.)

Abstract

This study investigates the treatment of high-organic-load chip industry wastewater using electrocoagulation (EC) and its potential for sustainable agricultural reuse. EC performance was monitored via water quality parameters, while biological suitability was assessed through germination and early seedling growth of chickpea (Cicer arietinum L., cv. Azkan) seeds. EC experiments were conducted at raw pH (4.65) with 50 A/m² and adjusted pH (6.5 and 8.5) with 100 A/m² for 15–120 minutes. The highest treatment efficiency occurred at 100 A/m² and pH 6.5, with chemical oxygen demand and color removal of 36.63% and 97.37%, respectively. In plant trials, different dilutions of raw wastewater (HA) and EC-treated water (25%, 50%, 75%, 100%) were compared with distilled water controls. Data were analyzed using Python with two-way ANOVA and LSD tests (p<0.05). HA-100 and EC-100 treatments inhibited plumule and radicle growth. The highest germination was in EC-25 (95.45%), longest radicle (22 mm) and highest fresh biomass (6.80 g) in HA-50. These findings indicate a possible hormesis effect at low dilutions, suggesting EC-25 as the optimal strategy for germination and HA-50 for early seedling growth and biomass accumulation.
