The greenhouse experiment was conducted to evaluate the effect of black polyethylene (PE) plastic mulch on yield and some quality parameters of tomato. In the study, black PE mulch material was laid on raised beds and bare soil (not mulched) was used as control. Mulch did not affect plant height, fruit shape index, chroma and hue angle, firmness, soluble solids content, titratable acidity. Black PE plastic mulch had a positive influence on yield.Significantly higher stem diameter and yield were obtained from the black PE mulch application (17.23 mm and 18.78 kg da -1 , respectively) compared to the control (15.30 mm and 16.75 kg da -1 , respectively). On the other hand, vitamin C was higher in control (41.13 mg 100 g -1 ) than in the black PE mulch application.
This study was carried out to determine the effects of different growing media (peat + perlite, cocopeat, hazelnut husk, rock wool) and different humic acid doses (2, 4, and 8 ml L-1) on tomato plant growth. The performance of the seedlings from planting to fruit set was evaluated to determine the growth of the tomato plant. Fort his purpose; stem diameter (mm), plant height (cm), number of leaves, first flowering and first fruit set, total plant dry weight (g), root volume (m3), and relative growth rate (g cm-2 days-1) parameters were examined. According to the results, the highest stem diameter of 15 mm was obtained in the hazelnut husk media at a dose of 4 ml L-1 of humic acid. As a result, while the best root growth was obtained at 2ml L-1 humic acid doses in peat-perlite media, the fastest growth and N (3.33%), P (0.58%) and K (3.91%) content were obtained at 8 ml L-1 humic acid doses in cocopeat media. The best leafing, flowering and fruit set were obtained in cocopeat media with 2 ml L-1 humic acid doses. As a result, the highest relative growth rate (0.064 g cm-2 days-1) at 8 ml L-1 humic acid doses applied in the fastest growing cocopeat media.
In this study, the effects of tomato (Solanum Lycopersicum cv. Depar F1) seedlings grafted on three different rootstocks (Kudret, Hamarat, Pençe) on yield and some quality parameters of tomato plants grown in the greenhouse and open field were investigated. According to the results we obtained, while the plants grown in greenhouses grew up 42.3% faster than those grown in the open, an increase in yield was achieved by 265%. While TA and vitamin C values, among the fruit quality characteristics, came to the fore in the plants grown in the greenhouse, the fruit firmness values came to the fore in the tomatoes grown in the field. Kudreç rootstock came to the fore regarding yield and fruit quality characteristics. When the nutrient contents of the fruits were examined, the highest N, Ca and Mg were measured in greenhouse-grown tomatoes, while the highest O.M and Mn were measured in field plants. Hamarat rootstock has come to the fore in terms of fruit nutritional content. As a result, the importance of growing conditions for grafted plants to show their performance has been demonstrated again. However, it has been demonstrated for the first time that such successful results can be obtained, especially with organic plant nutrition methods.
Bu çalışmada; topraksız yetiştiricilikte domates ve marul üretiminde kullanıldıktan sonra açığa çıkan 4 ortamın [domates atıkları (DA; doğrudan kullanılan, ÖDA; ön işlem gören), Hindistan cevizi lifi (%100), Torf + Perlit karışımının (%65+%35)] marul (Lactuca sativa var. capitate) ve maydanoz (Petroselinum crispum) fidesi yetiştiriciliğinde kullanım durumu test edilmiştir. Kontrol ortamı olarak torfun kullanıldığı çalışma, sonbahar döneminde ısıtmasız cam serada yürütülmüştür.Yetiştirme ortamlarının gövde çapı(mm), fide boyu(cm), kök uzunluğu(cm) ve fide yaş ağırlığı(g) üzerine önemli etkileri belirlenmiştir (p˂ 0.05). Marul ve maydanoz fidelerinin kalitesinde DA ve ÖDA atıklarının diğer yetiştirme ortamlarına iyi bir alternatif olabileceği belirlenmiştir.
Bu çalışmada, aşılı ve aşısız olarak yetiştirilen domates fidelerinin (Solanum lycopersicum cv. SC-2121) dikim sonrası ilk meyve tutum dönemine kadar büyüme hızlarının belirlenmesi amaçlanmıştır. Bu amaçla SC-2121 domates çeşidi üç farklı domates anacı (Kudret F1, Hamarat F1, Pençe F1) üzerine aşılanmıştır. Ayrıca, aşısız SC-2121 hibrit domates çeşidi kontrol olarak kabul edilmiştir. Domates bitkilerinde en yüksek gövde çapı (12.3 mm), bitki boyu (35 cm) ve kök izdüşüm alanı (1.405 cm2) Pençe F1 anacı üzerine aşılanan domates bitkilerinde belirlenmiştir. En yüksek yaprak klorofil içeriği (50 CCI) ve nispi büyüme hızı (0.037 gm-2 gün-1) Hamarat F1 anacı üzerine aşılanan domates bitkilerinden elde edilmiştir. Çalışma sonucunda aşılama yapılmış bitkilerde bitki nispi büyüme hızı ve kalitesi artırılmıştır. Ancak, aşısız olarak yetiştirilen domates bitkilerinin büyüme hızı Kudret F1 ve Pençe F1 anacına aşılanmış bitkiler ile benzerlik göstermiştir. Ayrıca, kontrol bitkilerinde gövde çapı ve bitki boyu değerleri Kudret F1 ve Hamarat F1 anacına aşılanan bitkilerden daha üstün olmakla birlikte Pençe F1 anacına aşılanan bitkiler ile benzer bulunmuştur.
