Comparison of bed planting-furrow irrigation with conventional planting-flood irrigation in durum wheat (T. durum Desf) in southeastern Turkey.
There is no clear consensus regarding the advantages of bed planting with furrow irrigation over conventionally irrigated cropping. This 3-year study from Southeastern Turkey aimed to assess the limits to some input savings in bed planting-furrow irrigation in terms of yields and profitability of durum wheat. Field trials were carried out using a randomized complete block design with six treatments and tree replications: T1: Conventional Planting-Flood Irrigation (CP-FI) with recommended practices for seed rate, chemical fertilizers and chemical weed control; T2: Bed Planting and Furrow Irrigation (BP-FI) with recommended input rates as in T2; T3: BP-FI with 10% input reduction; T4: BP-FI with 20% input reduction; T5: BP-FI with 30% input reduction; T6: BP-FI with 40% input reduction. The trial had four replications at each location over three cropping seasons, i.e., Akçakale (2004-05, 2005-06) and Koruklu (2006-2007). Individual and combined analysis of variance were performed for grain yields, market prices based on quality assessment, protein content and both 1000-kernel and hectoliter weights. Profitability was assessed with partial budget analysis. Except for yields, there was little effect of treatments on the other variables. Based on yields and economic analysis, the conventional system with flood irrigation was superior to the bed and furrow system, even when the inputs were reduced in such a system. The work demonstrates the site-specific nature of any new technology as there are several local biological and economical factors to be considered.
