RESIDUAL EFFECT OF ORGANIC AND INORGANIC NITROGEN FERTILIZERS ON WHEAT YIELD PRODUCTION AND SANDY SOIL FERTILITY
A field experiment was conducted during winter season of 2002/2003 at the experimental Farm, Faculty of Agriculture, ZagazigUniversity, El-Khattara region. Sharkia Governorate, to study the residual effect of organic manure "Rabbit and Farmyard manure" which was added to a sandy soil for a pearl millet crop, and the effect was assessed for a succeeding wheat crop. The sandy soil was treated before growing the pearl millet in summer season with the following treatments: no manure, rabbit manure, and farmyard manure FYM both at 10 metric ton/fed. Inorganic N as ammonium sulphate, 20.5% N was added at the rate 0, 20, 40 and 60 kg / fed to the wheat crop. The obtained results could be summarized as follows:
The results revealed that the nitrogen fertilizer "organic and inorganic" was very important to wheat in such soil regardless the form of added nitrogen. Rabbit manure (RM) alone or combined with mineral-N showed more residual effect in all parameters than farmyard manure.
Generally, the obtained results revealed that the residues of organic manure increased grain yield, straw yields biological yield, harvest index, N, P, K uptake in straw and grain, nitrogen use efficiency and biomass nitrogen recovery % compared to the control. Efficiency of added mineral-N expressed as N-use efficiency (NUE) or N-utilization efficiency (NUTE) decreased with increased mineral N fertilization level, and increased with rabbit and farmyard manure application.
Results indicate that N, P, K uptake by wheat plants were increased with increasing nitrogen levels addition, also RM alone or combined with mineral N caused an increase in nutrient uptake in wheat than FYM alone or with added N. The highest value was obtained by using organic manure combined with 60 kg N/ fed.
Agronomic and physiological efficiencies for wheat yield was increased with RM than FYM. There was interaction between nitrogen levels and organic manure and significantly affected protein contents. The highest values of 293.4 kg / fed were obtained with (RM + 60 kg N / fed). The residual effect of RM was much greater than FYM particularly under conditions of no N addition.
Residual effect of organic manure caused a decrease in soil pH, and an increase in organic matter content. Soil salinities and total nitrogen content of soil increased compared to manuring.
The results indicate that application of organic manures (RM & FYM) increased the soil content of organic carbon. The C/N ratio, in studied soil was generally decreased by addition of the organic manures, the decrease was more pronounced with RM treatment as compared with FYM treatments.
It can be concluded that the residual effect of 10 ton organic manure/ fed resulted in an increase in wheat yield, improving sandy soil properties and considered more safe and fusible for a long period from the agronomic and economic point.
