Oğuzhan Cerit | Derya Öğüt Yavuz
Şeker pancarı yetiştiriciliğinde Amaranthus retroflexus L. önemli yabancı otlardan biridir. Çalışmada, ekim öncesi chloridazon (C), çıkış öncesi ve sonrası metamitron (M) ile çıkış sonrası ethofumesate + phenmedipham + desmedipham + lenacil (EPDL) etkili maddeli herbisitlerin ve bazı kombinasyonlarının uygulanması sonucu hayatta kalan A. retroflexus bitkilerinden toplanan tohumların çimlenme kapasitelerinin belirlenmesi amaçlanmıştır. Toplam çimlenme oranı (%), normal/anormal çimlenme oranı (%), ortalama çimlenme zamanı (gün) ve tohum ağırlığı (g) parametreleri belirlenmiştir. Sonuç olarak; chloridazon + ethofumesate + phenmedipham + desmedipham + lenacil 2, chloridazon + metamitron (çıkış sonrası) ve metamitron (çıkış öncesi) + metamitron (çıkış sonrası) kombinasyonlarına maruz kalan A. retroflexus bitkilerinin uygulama yapılmamış bitkilerden toplanan tohumlara kıyasla çimlenme özellikleri önemli ölçüde etkilenmiştir. Çimlenme özellikleri bakımından, en düşük toplam çimlenme oranı %85 ile metamitron (çıkış öncesi) + metamitron (çıkış sonrası) kombinasyonundan elde edilmiştir.

Levent Arın | Haydar Balcı
The research was carried out to investigate the effect of plant materials which are used as an alternative to synthetic chemicals in organic agriculture (thyme, mint, basil and garlic oil, hot pepper, and neem tree seed extract) and some organic acids (salicylic and jasmonic acid) on the germination, emergence, and seedling traits in broccoli (Brassica oleracea var. italica) cv. Jade. The seeds of broccoli treated with these materials were subjected to germination and emergence tests at 20±1°C and 60±5% RH in autumn period. After that, all seeds (including untreated) were kept at 5±1°C and again evaluated for germination, emergence, and seedling traits in spring period. In spring period, the seeds treated with neem seed extract gave highest germination percentage (91.75%). Also, they germinated in shortest time (3.80 days). The lowest germination/emergence percentage and highest mean germination/emergence time was obtained from the seeds treated with thyme oil in both periods. The seeds treated with basil oil had the higher infected seedlings than others. There were no significant differences among treatments in term of seedling traits (except leaf number).

The bean plant is a legume plant that binds free nitrogen of the air by the nodosity formed in the roots. For this reason, it was aimed to investigate the effect the pod of bean characteristics of bean by applying different doses of phosphorus and nitrogen on Göksun beans cultivar. In the study, 0, 3, 6, 9 kg da-1 phosphorus and 0, 4, 8, 12 kg da-1 nitrogen doses were applied to Göksun bean variety. The pod length (cm), pod width (mm), pod diameter (mm), number of pods per plant (edet), weight of a single pod (g), number of seeds per pod (pieces), weight of single seeds (g) of Göksun bean cultivar were investigated. In the research, it was noted that the effect of phosphorus doses only on the pod diameter, the effects of nitrogen doses on the pod length, pod diameter, pod width, single seed weight and seed number of pod were significant. The differences in number of pods in the plant, seed number of pods, pod length, pod weight, single seed weight in terms of phosphorus and nitrogen interaction were founded statistically significant. According to the results of the research, it was determined that 4 kg da-1 and above nitrogen dose applications made a positive contribution in terms of pod properties

Ipaz Cuastumal, Claudia Maricel(Universidad Nacional de Colombia) | Madero Morales, Edgar(Universidad Nacional de Colombia) | Ramírez Náder, Miguel(Universidad Nacional de Colombia) | Gómez Carabalí, Arnulfo(Universidad Nacional de Colombia)
Se evaluó la relación entre la producción de forraje fresco y la materia seca en dos cortes de Manihot esculenta Crantz HMC 1 y el régimen de humedad (RHS) de un Haplustoll éntico fragmental francoso a francoso fragmental isohipertérmico mezclado superactivo 0 - 1%. La humedad en el suelo se registró tres veces por semana, en un sistema de producción experimental en el municipio de El Cerrito (departamento del Valle del Cauca), Colombia. Se evaluaron las densidades de siembra de 40.000; 71.429 y 100.000 plantas/ha en un diseño de bloques completos al azar con cuatro repeticiones. Se presentaron diferencias (P < 0.05) por efecto de la distribución del tamaño de las partículas sobre la humedad aprovechable. Para la producción de forraje fueron determinantes los mesoporos del suelo y la lámina de agua fácilmente aprovechable (LAFA) de los primeros 10 cm para el primer corte y entre 25 cm y 40 cm para el segundo. La densidad de siembra no afectó (P > 0.05) la producción de materia seca y forraje verde. | The relationship among Moisture Regime in an Entic Haplustoll loamy fragmental over fragmental loamy isohiperthermic mixed super active 0-1% ( evaluated three times per week) and forage production ( evaluated during two harvest) was investigated in a cassava forage crop production system in the Cauca Valley department, Colombia. A sowing rate of 40,000, 71,429 and 100,000 plants ha-1, under a complete randomized block design was used. Significant differences (P < 0.05) on the effect of the amazement of the soil particle size over the available soil moisture were observed. Soil mesopores and soil available water were determinant on forage yield in the first harvest at 0-10 cm depth and in the second harvest at 25-40 depth. The sowing rate did not have significant effect on dry matter production or in the green forage under the environmental conditions of the experimental site.

The main objective of the study is to determine the structure of seed usage of the wheat farms and development of its production in Isparta and Burdur provinces. The primary data used in this study were obtained by questionnaires in the region. Data obtained from the 150 of wheat cultivation farms belongs to the 2011 production period. The most important problems faced by farms were the low product prices and high input prices. Farmers pointed out that the development of wheat production can be provided by reducing the input costs such as; fertilizer, fuel, pesticide etc. The 97.3% of the wheat growing farms in the region make the seed dressing. About 52.7% of the interviewed enterprises are storing wheat and 74.7% of the farms are aware of the wheat varieties grown. About 52% of farms were found to be the use of certified seed. Certified seed usage rate is higher in the province of Isparta (69.3%) than Burdur. There is also a statistical difference in the use of certified seeds among the provinces. In the region, it was found that farms do not have enough information about the usage of certified seed and therefore it is necessary to transfer knowledge to the grower by the extension services.
