- MakaleYalnız künye2015Effect of applications of organic solid cattle manure on Hungarian vetch and barley intercropping mixtures grown on soils of different depths
Yolcu, H.
Sloping fields on soils of shallow depth to tillage are commonly left uncultivated in many parts of the world. This study was conducted to compare the effects on morphological traits, dry-matter (DM) yield, legume ratio (LR), crude protein content (CP), crude protein yield (CP yield) and mineral concentrations (N, P, K, S, Ca, Cu, Fe, Mg, Mn, Na, B and Zn) of Hungarian vetch (Vicia pannonica Crantz.) and barley (Hordeum vulgare L.) grown in intercropping mixtures in response to three rates of organic solid cattle manure application (M0: 0, M1: 10, M2: 20 t ha-1). Experimentation was conducted on soils of two different soil depths [shallow (8-12 cm; low-medium erosion risk) and normal soil depth (18-22 cm; no erosion risk)] on a sloping field in the 2006-2007 and 2007-2008 growing seasons at Gumushane, Turkey. Herbage harvested on the shallow depth area had 22-73% less DM yield, 14-72% less CP yield, 6-9% greater CP content and generally higher minerals contents than herbage from the normal soil depth area. Cattle manure applications increased DM yield by about 23%, increased CP content and CP yield, and also increased the contents of most minerals in herbage of the intercropping mixtures, relative to the control, averaged over the two soil depths. It is suggested that, for areas with shallow soil depths that are prone to erosion, plant cover should be used for forage production, and that fertilization with solid cattle manure at 20 t ha-1 can support production of quality forage of acceptable DM yield.
- MakaleAçık Erişim2014Yield and quality traits of some perennial forages as both sole crops and intercropping mixtures under irrigated conditions
Sayar, Mehmet Salih; Han, Yavuz; Yolcu, Halil; Yücel, Hatice
A field study was conducted to evaluate the yield and quality traits of sole lucerne (L), sole bromegrass (B), sole tall fescue (T), sole orchardgrass (O), sole ryegrass (R), and lucerne + bromegrass + tall fescue (L+B+T) and lucerne + bromegrass + tall fescue + orchardgrass + ryegrass (L+B+T+O+R) intercropping mixtures at the GAP International Agricultural Research and Training Centre under the irrigated conditions during 2009, 2010, and 2011 in the Southeastern Turkey. Dry matter yield (DMY), crude protein content (CPC), crude protein yield (CPY), acid detergent fiber (ADF), neutral detergent fiber (NDF), dry digestible matter (DDM), dry matter intake (DMI), total digestible nutrients (TDN), and relative feed value (RFV) were determined in this study. The L+B+T intercropping mixture and sole lucerne provided higher yields than the other crops tested. Sole lucerne had higher protein and quality contents than the other sole perennial forages and intercropping mixtures. The L+B+T intercropping mixture had a higher yield and quality than the other sole perennial forages and intercropping mixtures, with the exception of sole lucerne.
- MakaleYalnız künye2012Yield and quality characteristics of sunflower silages in highlands
Guney, Erdal; Tan, Mustafa; Yolcu, Halil
This research was carried out to compare the yield and quality characteristics of four sunflower (Helianthus annuus L.) genotypes (i.e., confectionery Tekirdag landrace, confectionery Erzurum landrace, oilseed Sirena and oilseed C70165 hybrids) and one corn (Zea mays L.) genotype (i.e., SZE TC-S13 hybrid) in the Agriculture Faculty of Ataturk University in the east of Turkey during the period between 2005 and 2006. The study was designed in a randomized complete block design with five treatments replicated three times. The genotypes were evaluated in terms of forage properties as well as chemical and physical properties of silages in both years. According to the results, the corn genotype had better yield and silage qualities than sunflower genotypes. But crude protein contents of silages of sunflower genotypes were superior in comparison to the corn genotype. Also amongst sunflower genotypes, confectionery Tekirdag and Erzurum landraces had slightly higher silage qualities than oilseed sunflower hybrids.

Yolcu, Halil; Gunes, Adem; Gullap, M.Kerim; Cakmakci, Ramazan
This research study was designed to determine the effects of plant growth-promoting rhizobacteria (PGPR) on some morphological characteristics, yield and quality contents of Hungarian vetch (Vicia pannonica Crantz.) in the Kelkit Aydi{dotless}n Dogan Vocational Training School Research Area during 2008-2009 and 2009-2010 plant growing season. The research consisted of a control (without plant growth-promoting rhizobacteria) and 12 different plant growth-promoting rhizobacteria (Pseudomonas putida PPB310, Bacillus cereus BCB51, Pantoea agglomerans PAB58, Pseudomonas fluorescens PFC82, Pseudomonas fluorescens PF84, Arthrobacter mysorens AM235, Paenibacillus polymyxa PP315, Pantoea agglomerans PAA362, Bacillus atrophaeus BA361, Bacillus megaterium BMA424, Bacillus megaterium BMA479 and Bacillus subtilis BS521) seed inoculations and three replicates. Some morphological characteristics (stem diameter, plant height and leaf number), dry matter yield, crude protein, crude protein yield, ADF, NDF, macro and micro-elements (B, Ca, Na, K, Mg, P, S, Cu, Fe, Mn and Zn) were tested in the research study. According to the results of the research study, some of the PGPR treatments had positive effect on morphological characteristics (especially PFC82, BA361 and PAB58), dry matter yield (very little PAA362), crude protein (very little PFC82), ADF and NDF (especially BA361) and macro and micro-elements (especially PAA362) of Hungarian vetch.
- MakaleYalnız künye2011Application of cattle manure, zeolite and leonardite improves hay yield and quality of annual ryegrass (Lolium multiflorum Lam.) under semiarid conditions
Yolcu, Halil; Seker, Hayati; Gullap, M. Kerim; Lithourgidis, Anastasios; Gunes, Adem
A field experiment was conducted under semiarid conditions to investigate the effect of cattle manure (20 and 40 t ha -1), zeolite (250, 500 and 750 kg ha -1), and leonardite (250, 500 and 750 kg ha -1) applications on hay yield and nutrient quality of annual ryegrass. Application of manure, leonardite, and zeolite increased ryegrass hay yield by 4, 24 and 47%, respectively compared with the control. In all fertilizer levels, the crude protein (CP) content was greater than the control and increased as the level of each fertilizer was increased. Most fertilizer treatments (except from the first level of cattle manure) gave higher CP yield than the control. All fertilizers increased the content of K, S, Ca, Mg, Fe, Mn and B of ryegrass hay as compared with the control, whereas they had no significant effect on Cu and Zn content. The content of most minerals increased as the amount of manure and leonardite applications increased. In conclusion, all fertilizers (especially zeolite) showed great potential for use in organic agriculture as they can improve plant growth and soil conditions in the long term.
- MakaleYalnız künye2011Effect of plant growth-promoting rhizobacteria and manure on yield and quality characteristics of Italian ryegrass under semi arid conditions
Yolcu, Halil; Turan, Metin; Lithourgidis, Anastasios; Çakmakçi, Ramazan; Koç, Ali
Plant growth-promoting rhizobacteria (PGPR) appeared as a promising alternative for organic fertilization. A field experiment was carried out to evaluate the effects of PGPR and solid cattle manure application on yield, quality, and mineral concentrations of Italian ryegrass (Lolium multiflorum Lam.) under semi arid conditions in Turkey. The treatments included: three manure application rates (i.e. M1, 10; M2, 20; and M3, 30 Mg ha -1), five PGPR strains (i.e. RC11, Bacillus subtilis; RC21, Variovorax paradoxus; RC105, Paenibacillus polymyxa; RP24/3, Paenibacillus polymyxa; and RF29/2, Pseudomonas putida), and a control (without bacteria or manure application). Manure application did not increase yield of Italian ryegrass, whereas the treatments with RC21 and RP24/3 rhizobacteria provided the highest dry matter yield. All PGPR and manure applications increased crude protein concentration of Italian ryegrass. The M3 manure rate and most treatments with PGPR (except RC11) produced greater crude protein yield than that of control. In addition, concentrations of P, S, Mg, Cu, Zn, and Fe in most PGPR and manure applications were greater than those of control.
- MakaleYalnız künye2009Yields and qualities of some red clover (Trifolium pratense L.) genotypes in crop improvement systems as livestock feed
Tavlas, Ayten; Yolcu, Halil; Tan, Mustafa
The objective of this study was to compare twenty-five genotypes of red clover (Trifolium pratense L.) in terms of yield (in 2000 - 2004) and quality performance (in 2000 - 2001) for animal feeding. The genotypes were evaluated for dry matter yield (DMY), crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), digestible dry matter (DDM), dry matter intake (DMI), relative feed value (RFV), total digestible nutrients (TDN), net energy-lactation (NEl), net energy-maintenance (NEm) and net energy-gain (NEg) content. There were significant differences in DMY (P < 0.01), CP, ADF, NDF, DDM, DMI, RFV (P < 0.05), TDN, NEl, NEm and NEg (P < 0.01) amongst the genotypes. The Rajah cultivar had the highest DMY (13629 kg ha-1) amongst the genotypes according to five year results. While the highest CP (15.94%), NDF (50.59%), DDM (68.68%), TDN (66.50%), NEl (0.70 Mcal/1b), NEm (0.76 Mcal/1b) and NEg (0.44 Mcal/1b) were determined in the L-818 line, the lowest ADF (25.96%) was also found in the L-818 line. The highest DMI (3.16%) was observed in the Hamua cultivar. The highest RFV was determined in the Tohum Islah ecotype (156), the Hamua (155), the Orbit (154) cultivars and the L-812 (154) line. Our results showed that there were large variations in terms of yield and quality performances amongst the red clover genotypes for animal feeding. The Rajah, L-832 (selected from wild forms) and Pawera had the highest yields amongst the genotypes. The L-818, L-812 lines (selected from wild forms), Tohum Islah ecotype, Lucrun and Redwent cultivars were superior in terms of forage quality properties (low in ADF and NDF and high CP, DDM, DMI, RFV, TDN, NEl, NEm, NEg) than the other red clover genotypes.
- MakaleYalnız künye2009Effects of nitrogen and phosphorus fertilization and seeding patterns on chemical composition of Lucerne and smooth brome grass intercropping system
Yolcu, Halil; Serin, Yunus
Intercropping has been used widely in forage plant production all around the world. In intercropping systems, forage plants need different requirements are grown together. Requirement of fertilization and seeding pattern of intercropping differ from mono cropping. The research goals were to evaluate the effects of various seeding patterns and fertilization on the crude protein and chemical content of lucerne-smooth brome grass mixture under field conditions in 2002-2003. Lucerne and smooth bromegrass mixtures were established with different seeding patterns (mixed, alternative and cross-seeding), N fertilizer rates (0, 60 and 120 kg N ha-1) and P fertilizer rates (0, 40, 80 and 120 P2O5 ha-1). The results of this study indicated that different seeding patterns, N and P fertilization affected chemical contents of alfalfa and smooth brome grass mixture in the intercropping system. Depending on different seeding patterns, N, Ca, K and Mg content varied significantly, but no P content in the intercropping system. Nitrogen application increased N content and P application likewise increased P content. While P application increased N content, N application had no effect on the P content of the intercropping. Calcium and K did not vary significantly depending on N and P fertilization; yet, a relationship between P application and Mg content was determined.
- MakaleYalnız künye2009Evaluation of annual legumes and barley as sole crops and intercrop in spring frost conditions for animal feeding I. Yield and quality
Yolcu, Halil; Dasci, Mahmut; Tan, Mustafa
This study evaluated sole grass pea (Lathyrussativush.), sole common vetch (Vicia sativa L.), sole barley (Hordeum vulgare L.), common vetch + barley intercrop, common vetch (I) and barley (I) in terms of yields and quality properties in 2006-2007 at Kelkit Aydin Dogan Vocational Training School Research Station of Gumushane University, Turkey. Intercrop plants were separated as common vetch (called as common vetch I) and barley (called as barley I). Plants were seeded in April of both years in a randomized complete block design with 3 replications. The study plots were 3.0 m long by 1.68 m wide, with 24 cm row spacing. Each plot was fertilized with 20 ton ha-1 organic farmyard manure. The year effects were significant in dry matter yield, crude protein, crude protein yield, acid detergent fiber and neutral detergent fiber. The legumes especially were injured by frost in 2007. Significant differences were found in terms of Dry Matter Yield (DMY), Crude Protein (CP), Crude Protein Yield (CPY), Acid Detergent Fiber (ADF), Neutral Detergent Fiber (NDF), Dry Matter Intake (DMI), Dry Digestible Matter (DDM) and Relative Feed Value (RFV) amongst all the plants. Sole common vetch and sole barley had good properties in DMY, CP and CPY. Sole grass pea, common vetch (I), sole common vetch and intercrops showed good quality properties in ADF and NDF. Sole grass pea especially, sole common vetch and common vetch (I) had good quality properties in DMI, DDM and RFV. Farmers should prefer sole common vetch and sole grass pea cultivation in yield and quality and regulate their seeding times according to days with frost in similiar conditions.
