3-Ketovalidoxylamine A C-N lyase and glucoside 3-dehydrogenase (G3DH), two key enzymes for valienamine synthesis, are produced by Stenotrophomonas maltrophilia. The condition of producing 3ketovalidoxylamine A C-N lyase and G3DH was optimized. Validamycin A was showed to be suitable carbon source for C-N lyase and G3DH synthesis. Maximum C-N lyase production was achieved by adding 100 ml cultur...

The present study assessed the effect of seed inoculation with single or multiple plant growth-promoting rhizobacterial (PGPR) strains on yield in spring wheat (Triticum aestivum spp. vulgare var. Kırık) and barley (Hordeum vulgare cv. Tokak) plants in both greenhouse and field conditions during the years 2007 and 2008. The treatments of wheat and barley plants during the first year include...

Fertilizer management plays an important role in obtaining satisfactory yields from maize. In addition, fertilizer management is essential for achieving sustainable agriculture and protecting the environment. This research was conducted by split plot experiment based on randomized complete block design with four replications. Main factor was integrated with chemical and biological fertilizers i...

Faced with the contrasting results of inoculation and co-inoculation in bean crop, an experiment was carried out pots, objective evaluating performance plant treatments inoculated or co-inoculated Rhizobium tropici Azospirillum brasilense, via seeds, without chemical treatment fungicide insecticide, combined 4 top-dressing nitrogen doses (0, 30, 60, 120 kg ha-1), a ‘Latossolo Vermelho-Amarelo d...

The influence of VAM fungi and bacterial biofertilizer (BBF) with 50% reduction in the recommended dose of (N and P) chemical fertilizers on leaf quality traits of mulberry variety (S-13) and its impact on silkworm (PM ? NB4D2) growth and cocoon characters were studied under semi-arid conditions. Four different treatments were imposed i.e., T1: Control (only 100% NPK); T2: VAM (50% cut in P); ...

The effects of two entomopathogenic fungal endophytes, Beauveria bassiana and Purpureocillium lilacinum (formerly Paecilomyces lilacinus), were assessed on the reproduction of cotton aphid, Aphis gossypii Glover (Homoptera:Aphididae), through in planta feeding trials. In replicate greenhouse and field trials, cotton plants (Gossypium hirsutum) were inoculated as seed treatments with two concent...

A field experiment was carried out in Zaid 2022 at the Department of Agronomy's Agricultural Research Farm Prayagraj (Uttar Pradesh). There are three planting geometries used 30 cm x 10 cm, 40 and 50 cm. nitrogen management treatments 50% Recommended Dose Nitrogen (RDN) through inorganic fertilizer, RDN th rough fertilizer combination with provided yard manure Azotobacter seed inoculation, fert...

This research has been done to examine the effect of bio-priming on germination parameters related to seeds of canola cultivar (Hayola 401) under high salinity as factorial in seed laboratory of Shahed University based on a Completely Randomized Design (CRD) in three replications. Experimental factors included bio-primin...

Chickpea (Cicer arietinum L.) germplasm, collected from diverse research centers of the world were characterized for nodulation (Nod+ or Nod-) and evaluated for response to seed inoculation with Rhizobium leguminosarum in terms of number of nodules plant-1 and seed yield plant-1. Forty three genotypes, procured from Nuclear Institute for Food and Agriculture (NIFA) Peshawar, Gram Research Stati...

introduction the demand for food and agricultural products are increasing in a line of population increasing in the world (alexandratos, 2003). it is possible to increase the quality and quantity of agricultural products via extending the farms and producing more products (astaaraei and koocheki, 1995). environmental problems caused by synthetic fertilizers and the high levels of producing and ...
