The Effects of Planting Time and Combination on the Nutrient Composition and Digestible Dry Matter Yield of Four Mixtures of Vetch Varieties Intercropped With Barley
(Tubitak Scientific & Technological Research Council Turkey, 2007) Bingol, N. Tugba; Karsli, M. Akif; Yilmaz, I. Hakki; Bolat, Duran
The aim of this study was to determine the chemical composition, digestibility, energy content, and digestible dry matter yield of 4 mixtures of different vetch varieties intercropped with the same barley at 3 different planting times under Eastern Anatolian conditions. Four different vetch species, i.e. common (Farukbey-2001), Hungarian (Tarim Beyazi-98), hairy (Selcuklu-2002), and wooly pod (Segmen-2002), intercropped with barley (Tokak-157) were utilized. The mixtures of vetches intercropped with barley were planted on 7 October 2003 (I), 7 November 2003 (II), and 10 April 2004 (III), and each variety/planting time was randomly assigned to 3 replications. The mixtures of vetches intercropped with barley were harvested by hand using clippers when the barley started spiking and vetches were at 1/4 flowering. All samples were analyzed for dry matter (DM), ash, crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) content. In vitro dry matter digestibility (IVDMD) of the samples was also determined. While DM and organic matter (OM) content did not differ, CP, NDF, and AIDE content were significantly different among the different mixtures of vetch intercropped with barley (P < 0.05). IVDMD, metabolizable energy (ME), and net energy lactation (NEL) values were also significantly different among the mixtures of vetch intercropped with barley (P < 0.05). Digestible DM and ME yield of the mixtures were significantly affected by planting time (P < 0.05), but not variety. However, CP yield of the vetch-barley mixtures was significantly affected by both planting time and variety (P < 0.05). It can be concluded that all of the mixtures of vetch intercropped with barley had significantly higher digestible DM and CP yield when planted on 7 October 2003. Thus, October should be preferred for planting of the mixtures of vetch intercropped with barley in Eastern Anatolia. If a greater CP yield in addition to digestible DM yield is desired from vetch-barley hay, then common vetch should not be the choice.
A Research on Forages Cultivation, Rangeland Usage and Socio-Economical Structure of Van Province
(Ankara Univ, Fac Agr, 2008) Sahin, Kasim; Yilmaz, I. Hakki
This study was conducted to determine cultivation of forage plants and usage of ranges in Van. We interviewed with 122 forage plants producer in Van and its three administrative where forage plants cultivated commonly. Dates were collected by asking questionnaire to people living in villages in 2007. Average population in each farm was 10.02. Average age of interviewed peoples was 40.40 year, their average education period was 8.16 year, and their average agricultural experience was 22.86 year. Forage production area in each farm was 29.38 decar, its 20.67 decar was alfalfa and its 8.71 decar was sainfoin. Average cattle number in each farm was determined as 4.61 (BBHB) and average sheep and goat number was determined as 36.08. Forage plants produced in each farm were used to feed animal in same farm. Besides, hays were bought from outside in some feeding period. Concentrate feeds are provided from administrative or Van city. Straw is the most used hay in farms for animal feeding and alfalfa, sainfoin, meadow hays follows it, respectively. 76.22 percent of farmers stated that animals graze on rangelands. It was also determined that animals start to graze on rangelands in April (78.49 %), and it lasts in December (65.59 %).
A Research on Forages Production and Problems in Gurpinar District of Van
(Ankara Univ, Fac Agr, 2008) Sahin, Kasim; Yilmaz, I. Hakki
The purpose of thsis research was to determine production and problems of forages grown in Gurpinar district of Van. Eighty-seven forage producers were interviewed at Gurpinar district of Van province where forages are being produced intensively. The data belong to 2006 production period and were collected by means of questionnaires interviewing with persons in village. On these farms, the average population per farm was 6.74 people. The average farmer's age were 42.67 years old and had 23.49 years of farm production experience in overall farms. The average farm size was 52.05 decare. About 60.25% of the total land is irrigated and the remaining 39.75% is dry land. In 2006, 26.87 decare average land was planted with forages which are mainly alfalfa (20.14 da), sainfoin (5.34 da) and silage corn (1.39 da). The average cow, sheep and goat per farm was 2.05, 35.82 and 8.70, respectively. The main problems of forage production in region are lack of forage cultivation information such as, irrigation methods, usage of certified seed, and government related programmers (forage encourage programme). Also, they do not have enough tool and equipment for forage cultivation. Therefore, farmers should be trained on the topics of forage cultivation. Also, if villagers establish a cooperative, they can get tools and equipment easily. In the region, development on dairy and fattening cow breeding are depend on forage production. Therefore, forage production in the region should be more encouraged, especially, alfalfa, sainfoin, and silage corn production,
