Effect of nitrogen fertilization and bacteria application in peanuton yield components ?
Peanut is a legume with the ability to accept the symbiotic nitrogen fixing bacteria to provide it needs. It would be critical in new areas which do not have previous peanut crop to inoculate the seed with proper type of nitrogen fixing Rhizobium bacteria. In addition in your situation in Turkey the conditions may be somewhat deficient in micronutrients which are essential for getting the most out of Rhizobium. Their is a comoly seed treatment which can be helpful in providing necessary Cobalt, Molybdenum and Zinc. Under alkaline soil conditions you may want to have a starter application of Phosphorus and at flowering particularly in acid soil condition the supply of boron and calcium can prevent abortion of flowers and hollow heart of the kernels. Potassium will be needed at the fill stages in low potassium soils. I would suggest getting a complete soil analysis to project your fertilization strategy and then use tissue analysis to fine tune your program.
- I think nitrogen only affects biomass, but it actually increases the number of flowers and the size of the fruit.
Truly speaking, I am not clear with the question posted here. Thus, I will be happy the initiator of this discussion, F.F. Asik would a bit elaborate here question or tell us what exactly wanted to know about the effect of N and bacteria on peanut. Then it will be easier to forward possible answers.
Peanut is a legume with the ability to fix nitrogen into the soil. The efficiency of the peanut to undertake this natural activities depends on the availability of the rhyzobium bacterial to enable the formation of root nodules. It is therefore important to know the nature of soil that will inform you to either use bacterial inoculations or not. The inoculants are use to coat the seeds before planting to enable peanut assimilate well in the soil thereby effectively capturing nitrogen for its use and also leaves residues for other crops.
The effect of nitrogen fertilization on peanut have been observed to contributing to vegetative growth and with lesser nut formation. However, it also depends on other micro nutrients in the soil. Soils that are rich in Phosphorus are likely to give more nuts than those lucking it.
