Leguminous crops, possessing root nodules, fix and utilize atmospheric nitrogen. They are thus not dependent on industrially fixed nitrogen but add up to 30 kg of nitrogen / hectare to the soil and improve its fertility. Access to mineral nitrogen often limits plant growth, and so symbiotic relationships have evolved between plants and a variety of nitrogen-fixing organisms. These associations ...

the plant promoting bacteria as biological fertilizers play an important role in increasing productivity and improving plant growth in stress condition. in order to evaluate the ability of plant promoting bacteria rhizobacteria on germination and growth of corn under salinity conditions, a pot experiment was conducted in factorial based on randomized complete block design with three replication...

A field experiment was conducted to assess the effect of farmyard (cattle) manure (FYM) and inorganic nitrogen (N) phosphorus (P) fertilizers on growth and tuber yield of potato (Solanum tuberosum L.). The treatments consisted of factorial combination of 4 levels of FYM (0. 10, 20 and 30 t h-1) and three levels of inorganic NP fertilizers (0, 33.3%, 66.6% recommended rates) laid out in a Random...

This Bulletin discusses several manufacturing processes for organic compound fertilizers overseas and in Taiwan. The different formulations of N-P2O5-K2O in the fertilizers are also reported. The yield response of different crops from the application of organic compound fertilizer reflects their superiority over organic fertilizers. Experiments also showed that the use of organic compound ferti...

ome organic fertilizers are suitable for greenhouse crops and can also fit the current ways of applying fertilizers commercially. However, not much information is available on plant response, nutrient supplying power, or the environmental impact of nutrient leaching with organic fertilizers. Not surprisingly, because of their differences in the makeup, levels of success in growing acceptable gr...

down-draught extractor fans are installed and protective clothing is worn. It is almost impossible to sterilize bone products and it would be a costly, indeed uneconomic, process. At a symposium at the Veterinary Public Health Association meeting in 1964 it was concluded that "considering the widespread distribution of anthrax spores in imported animal products, coupled with the small number of...

effects of various fertilizers such as farmyard manure (fm), urea, and plant growth promoting rhizobacteria (pgpr, including the genera azotobacter and azospirillium) were checked on yield, fatty acids, protein, and oil contents of sunflower. a two-year field experiment was conducted in a semi-arid region in iran in 2007 and 2008. the experiment was a split plot in a randomized complete block 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); t...

Brazil is an important peanut producer, but despite its high production, there still needs to be inoculant for the crop. In addition, use of microorganisms that promote plant growth (PGPM) not common, and this crop highly dependent on chemical fertilizers. An excellent alternative reduce fertilizers inputs in crops while reducing production cost environmental impact PGPM. The objective study wa...
