    Inoculation effect of arbuscular mycorrhizal fungi (AMF) on phosphorus (P) transfer from composted dung of cattle with a diet supplemented with powdered rock phosphate (RP) and their successive uptake by mung bean plants was assessed in alkaline soil. The efficacy of composted RP fed dung alone or/and in combination with AMF inoculums containing six different species were compared with SSP in six replicates per treatment in pots. The results showed that the association of AMF with composted RP fed dung had a positive effect on mung bean shoot (3.04 g) and root (2.62 g) biomass, chlorophyll (a, b), carotenoid contents and N (58.38 mg plant(-1)) and P (4.61 mg plant(-1)) uptake. Similarly, the percent roots colonization (56%) and nodulation of mung bean plant roots and their post-harvest soil properties were also improved by the inoculation of AMF together with composted RP fed dung. It is concluded that the combined application of AMF with composted RP fed dung has almost the same effect as SSP for improving mung bean plants growth and their nutrients uptake. Moreover, AMF inoculants can be used as a suitable biofertilizer in combination with locally available organic sources of fertilizers for improving P status and growth of plants in alkaline soils.

    Bitki Peptit ve Amino Asit Taşıyıcılarının Demir Taşınmasındaki Görevleri
    (2022) Aksoy, Emre; Maqbool, Amir; Yerlikaya, Bayram Ali; Wahid, Fazli
    Demir (Fe) bitkiler için önemli bir mikro-besin elementi olup, eksikliği bitki büyümesi ve gelişimini engelleyerek ciddi verim kayıplarına neden olur. Toprakta bulunan yarayışlı demirin bitkiler tarafından alınması ve bitki organlarına taşınması üzerine uzun yıllara dayanan detaylı çalışmalar gerçekleştirilmiştir. Bu çalışmalar sonucunda demirin bazı organik maddeler ile şelatlanarak taşınabileceği gösterilmiştir. Bu organik maddelerin içerisinde peptitler ve amino asitler yer almaktadır. Ancak, demirin peptitler ve amino asitler ile bitki içerisine alımı veya organlar arası taşınması üzerine detaylı çalışmalar yapılmamıştır. Gerçekleştirilen az sayıdaki çalışmada oligopeptit taşıyıcı (OPT) ve İlaç/Metabolit Taşıyıcı (DMT) aileleri üzerine odaklanılmıştır. Yakın zaman önce bitkilerde keşfedilen UMAMIT amino asit taşıyıcı ailesinin demir taşınmasındaki olası rolleri ise henüz incelenmemiştir. Bu derleme kapsamında, demirin bitki içine alınması ve organlar arası taşınmasından sorumlu taşıyıcı aileleri ile OPT, DMT ve UMAMIT ailelerinin demir-peptit ve demir- amino asit komplekslerini taşımadaki rolleri özetlenmiştir.

    Physico-chemical Status of Vermicompost Processed by Earthworm Specie Eisenia fetida
    (2019) Uğur, Senay; Ulutaş, Zafer; Wahid, Fazli
    Huge amount of organic wastes including agricultural field wastes, food wastes, municipal solidwaste and manures can be converted into a safe and usable product that can be used as a possiblesubstitute for chemical fertilizers. In this regard, the proposed study was designed with the aim toprepare macro and micronutrients rich vermicompost from different bio-wastes that can be used asa possible substitute to chemical fertilizers for improving plant growth. A 90 days vermicompostingexperiment was conducted in wooden boxes (1×1 m) containing animal manure and waste material(grasses, brewed black tea leaf and dry leaf) mixed in 3:1 ratio with a 2.5 cm thin layer of soil. Thematerial was at the bottom of the bed and around 10.000 earthworms of Eisenia fetida were settledin the box. The boxes were irrigated by sprinkled water daily and tilled from the top once every weekfor maintaining aeration and proper decomposition. The vermicompost production was continuedfor about 90 days in each box under 21-23°C room temperature. The results showed that by usinganimal manure and waste materials, the physical parameters like moisture content was increasedupto50 % on day 90. Likewise, the percent increase recorded for total N, organic N, total P andsoluble K content on day 90 was maximum in the vermicompost prepared from animal manure andwaste material. It can be concluded from this experiment that with the help of earthworm’s, differentfield and garden residues, wastes and manures can be converted into a nutrient rich and environmentfriendly vermicompost that can be used as a possible substitute to chemical fertilizers for improvingplant growth.
