EFFECT OF NITROGEN, PHOSPHORUS AND BIO FERTILIZERS ON MAIZE: II. YIELD AND ITS COMPONENTS
Two field experiments were carried out during two summer seasons 2001 and 2002 at the experimental Farm, Faculty of Agriculture, Kafr El-Sheikh, Tanta University to study the effect of [bio fertilizer notroben + phosphorus]with levels of nitrogen and phosphorus fertilization on yield and its components of maize plants of cultivar [single cross 10]. The results obtained could be summarized as follows A- Nitrogen levels plus notroben:
1- Addition of high dose of nitrogen [120 kg N/fed] alone caused a significant effect on ear length, straw yield /fed in ton, grain yield/plant in gm and feddan in ardab and crude protein percentage.
2- Addition of 60 kg N/fed plus notroben results in a significant increase in weight of 100 kernels..
3- Nitogen levels [90 kg N/fed] plus notroben caused a significant increase in shelling percentage seed index, straw yield /fed in ton and grain yield per plant in gm and per fed Dan in ardab
4- 120 kg N/fed plus notroben resulted in a significant effect on ear length, shelling percentage, grain yield per plant in gm or per fed Dan in ardab, crude protein percentage, straw yield /fed in ton and seed index.. B- Phosphorus levels plus phosphoren:
1- 15 kg P2O5/fed alone caused a significant increase in shelling percentage and seed index
3- 7.5 kg P2O5/fed plus phosphoren gave the significant increase in grain yield per fed Dan in ton, seed index, protein percentage and ear length, straw yield (ton/fed.).
4- 15kg P2O5/fed plus phosphoren resulted in a significant increase in ear length, grain yield in ardab or ton, straw yield /fed in ton and crude protein percentage.. C- Interaction effect:
The significant interaction was found on straw yield /fed in ton, ear length, grain yield per plant in gm or in ardab or ton and seed index. From the obtained results, it could be recommended that the use of bio fertilizer to minimize the chemical nitrogen fertilizer, reduced the costs of production and pollution which could be occurred be excessive use of chemical fertilizer.
