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.

A field experiment was conducted to evaluate the effects of some organic and chemical fertilizers on morphological, yield and quality properties and mineral contents of common vetch (Vicia sativa L.) between 2007 and 2008 in Gümüşhane, Turkey. Treatments were control (no fertilizer), liquid manure (LM = 51-52 L ha -1N), chemical fertilizer (CF = 30 kg N ha -1+ 80-100 kg P 2O 5ha -1), three leonardite doses (L 1= 2.8; L 2= 5.6 and L 3= 8.4 kg N ha -1), three zeolite doses (Z 1= 0.4; Z 2= 0.8 and Z 3= 1.2 N kg ha -1) and three solid cattle manure doses (SM 1= 34-35 kg N ha -1, SM 2= 68-70 kg N ha -1, SM 3= 102-105 kg N ha -1). Dry hay yield (DHY), leaf weight, stem weight, plant height, leaf number, crude protein content (CP), crude protein yield (CPY), acid detergent fiber (ADF), neutral detergent fiber (NDF), Ca, Fe, K, Mg, B, Cu, Mn, Na, Ni, P, Pb, S and Zn contents were determined. Organic and chemical fertilizer applications had significant effect (P<0.01) on DHY, leaf weight, stem weight, CP, CPY and mineral contents except leaf number, ADF and NDF in the both years. The plant height were significantly (P<0.05) affected by the treatments in the first year. The SM 2application in the first year and control and LM applications in the second year resulted to obtain improved yield components and crude protein yield. Z 2and Z 3applications also loomed large in terms of mineral contents.
