Fotovoltaik Sistem ve Damla Sulama Yöntemiyle Sulanan Fındıkta Sulama Uygulamalarının Verim ve Verim Bileşenlerine Etkisi

Abstract

Bu araĢtırmada fındıkta sulama amaçlı olarak kurulan 5 kWh fotovoltaik sistemin bileĢenlerinin kurulumu ve etkinlik değerlendirilmesi yapılmıĢtır. AraĢtırma, fındık bahçesinin damla sulama ile sulanmasını esas alan proje sahasında yürütülmüĢtür. Fındık bahçesine Temmuz ve Ağustos aylarında toprak nem takibi sonuçlarına göre sulama yapılmıĢtır. Fotovoltaik sistemden elde edilen verilere göre, offgrid akülü fotovoltaik sistem fındık bahçelerinin sulanmasında efektif olarak kullanılabilmektedir. Fındık verim değerleri de sulama suyuna olumlu tepki göstermiĢtir. ÇalıĢma alanında, sulama ile fındıkta verim artıĢı kontrol konusuna göre %89 oranında gerçekleĢmiĢtir. Bu bulgu ile özellikle güneye bakan yamaç arazilerde özellikle Temmuz ayında ve Ağustos baĢlangıcında fındığın sulama suyuna ihtiyaç duyduğu görülmektedir. Diğer taraftan fındık verimini etkileyen yaprak su potansiyeli, meyve ağırlığı ve meyve iç ağırlığı parametreleri sulama konularından etkilenmiĢtir. Bununla birlikte, meyve kalınlığı, iç randımanı, çotanaktaki meyve sayısı ve yaprak klorofil içeriği sulama konularından önemli oranda etkilenmemiĢtir.,In this study, the components of 5 kWh photovoltaic system, which is established for irrigation in hazelnut orchard, installed and evaluated. The research was carried out at the project site based on irrigation of hazelnut orchards with drip irrigation. Hazelnut orchard was irrigated in July and August in respect to soil water content measurement. Findings of photovoltaic system showed that offgrid system with the batteries is effectively usable for irrigation application of hazelnut orchards. Hazelnut yield values showed positive response to irrigation water. In the study area, full irrigation increased hazelnut yield was 89% compared to not irrigated parcel. This finding indicates that hazelnuts need irrigation water, especially in the south-facing hillside lands, especially in July and at the beginning of August. On the other hand, hazelnut yield, leaf water potential, fruit weight and fruit kernel weight parameters affecting hazelnut yield were affected by irrigation applications. However, leaf chlorophyll content, kernel ratio, kernel size, number of nut per cluster were not significantly affected by irrigation applications.
