  Can Zeolite Application Decrease the Need for Nitrogen in Silage Corn?

  Gül, Zeynep; Tang, Mustafa; Yolcu, Halil

  The effects of applications of zeolite, nitrogen and zeolite + nitrogen on yield, quality and some morphological traits of silage corn was researched at the Research Station of the Agriculture Faculty, University of Ataturk, Eastern Turkey, during 2012 and 2013. Treatments included a control, three zeolite (Z(1): 500, Z(2): 1000, Z(3): 1500 kg ha(-1)), three nitrogen (N-1: 50, N-2: 100, N-3: 150 kg ha(-1)) and nine combinations of zeolite + nitrogen. The experimental design was randomized complete blocks with three replications. The application of zeolite + nitrogen application enhanced silage yield by 5.8-18.9%, dry matter yield by 4.5-21.4%, corncob rate by 6.6%, plant height by 3.0-16.1% and leaf rate by 17.5%. Further, the application of zeolite + medium or low nitrogen application produced similar silage yield, dry matter yield, dry matter rate, crude protein content, ADF, NDF, corncob rate, stem rate, plant height and leaf rate in comparison to the highest level nitrogen application. The results indicate that the application of zeolite + nitrogen can be used to increase efficiency of nitrogen and to decrease nitrogen requirements in silage corn for yield and other parameters.

  Effects of nitrogen and phosphorus fertilization and seeding patterns on chemical composition of Lucerne and smooth brome grass intercropping system

  Yolcu, Halil; Serin, Yunus

  Intercropping has been used widely in forage plant production all around the world. In intercropping systems, forage plants need different requirements are grown together. Requirement of fertilization and seeding pattern of intercropping differ from mono cropping. The research goals were to evaluate the effects of various seeding patterns and fertilization on the crude protein and chemical content of lucerne-smooth brome grass mixture under field conditions in 2002-2003. Lucerne and smooth bromegrass mixtures were established with different seeding patterns (mixed, alternative and cross-seeding), N fertilizer rates (0, 60 and 120 kg N ha-1) and P fertilizer rates (0, 40, 80 and 120 P2O5 ha-1). The results of this study indicated that different seeding patterns, N and P fertilization affected chemical contents of alfalfa and smooth brome grass mixture in the intercropping system. Depending on different seeding patterns, N, Ca, K and Mg content varied significantly, but no P content in the intercropping system. Nitrogen application increased N content and P application likewise increased P content. While P application increased N content, N application had no effect on the P content of the intercropping. Calcium and K did not vary significantly depending on N and P fertilization; yet, a relationship between P application and Mg content was determined.
