Prinos, kvalitet i indeks ishrane azotom livade tipa Agrostietum capillaris pod uticajem đubrenja
No full textManaging N, P and K inputs in semi-natural meadow production systems is important for achieving maximum yields in livestock farming. The objective of the present study was to estimate the effect of different NPK levels (N0P0K0, N50P50K50, N100P50K50, N100P100K100, N150P100K100 and N200P150K150 kg ha-1 yr-1) on the yield, quality and nitrogen nutrition index (NNI) in a grassland community of Agrostietum capillaris (semi-natural meadow) in western Serbia. The study was conducted during the seasons of 2005-2008. The values of the investigated parameters, except for the unit N uptake, were the highest in 2004/2005 due to favorable climate conditions. The levels of nitrogen significantly increased all of the studied parameters compared to the control treatment, except for unit N uptake. Mineral fertilizers at N200P150K150 provided the highest green forage yield (25.12 t ha-1), dry matter yield (8.12 t ha-1), crude protein yield (876.3 kg ha-1), nitrogen uptake (140.2 kg ha-1) and nitrogen nutrition index (70.2%), and the lowest unit N uptake (0.0022 kg N kg DMY-1). The use of mineral fertilizers increased green forage yield, dry matter yield and crude protein yield, increasing fertilizer from lowest to highest rate increased fresh and dry matter yield, as well as protein yield. Based on the results of the study, monitoring of nutrition indices would be necessary in order to increase productivity and economic benefits.Unošenje N, P i K inputa u poluprirodnim livadama je vaţno za postizanje maksimalnih prinosa na stočarskim farmama. Cilj ove studije bio je procena uticaja različitih nivoa N, P i K (N0P0K0, N50P50K50, N100P50K50, N100P100K100, N150P100K100 and N200P150K150 kg ha-1 yr-1) na prinos, kvalitet i indeks ishrane azotom (NNI) u livadskoj zajednici Agrostietum capillaris (poluprirodna livada) u zapadnoj Srbiji. Studija je sprovedena tokom perioda 2005-2008. Vrednosti ispitivanih parametara, izuzev usvajanja azota po jedinici mase, bile su najviše u 2004/2005 zbog povoljnih klimatskih uslova. Nivoi azota su značajno povećali sve ispitivane parametre u poređenju sa kontrolnim tretmanom, osim usvajanja azota po jedinici mase. Đubrenje sa N200P150K150 obezbedilo je najveći prinos zelene krme (25.12 t ha-1), prinos suve materije (8.12 t ha-1), prinos sirovih proteina (876.3 kg ha-1), usvajanje azota (140,2 kg ha-1) i indeks ishrane azotom (70,2%), kao i najmanji unos azota (0,0022 kg N kg PSM-1). Upotreba mineralnih đubriva povećala je prinos zelene krme, prinos suve materije i prinos sirovih proteina, povećavanjem đubriva od najmanje do najveće količine je povećalo prinos sveže i suve mase, kao i prinos proteina. Na osnovu rezultata studije, praćenje indeksa ishrane azotom bi bilo neophodna mera u cilju porasta produktivnosti i ekonomske efikasnosti
Uticaj gustine useva na prinos i kvalitet krme sudanske trave
No full textDifferent plant density and agro ecological conditions per year was affected on forage yield and quality of Sudan Grass. In two years of investigation the highest yield has obtained with 30 kg/ha sowing rate (53,0 t/ha fresh forage and 15,96 t/ha dry matter), and the lowest with 60 kg/ha sowing rate ( 43,1 t/ha fresh forage and 12,93 t/ha dry matter). Fresh forage yield in 2002 was 54,9 t/ha, and dry matter yield was 16,65 t/ha. In 2003 fresh forage yield was 38,8 t/ha, and dry matter yield was 11,74 t/ha. Low sowing rate has affected crude protein content, crude fibre content, fat content and ash. High sowing rate has affected N-free extract content.U agroekološkim uslovima Istočne Srbije izvršeno je ispitivanje uticaja različitih gustina useva na prinos i kvalitet krme sudanske trave. Za ispitivanje je korišćena sorta sudanske trave NS-Srem. U radu je prikazan prinos zelene krme, udeo suve materije u vreme košenja, prinos suve materije i kvalitete suve materije (sadržaj sirovih proteina - SP, sirove celuloze SC, sirovih masnih materija SMM, pepela - Pe i udeo bezazotnih ekstraktivnih materija - BEM) Najviši prinosi zelene krme, odnosno suve materije ostvareni sa 30 kg ha-1 semena. Na visinu prinosa značajan uticaj su imali vremenski uslovi tokom vegetacionog perioda. Najviši prinosi ostvareni su prve godine istraživanja (55,9 t ha-1 zelene krme, ili 16,6 t ha-1 suve materije). Odnosno, u drugoj godini ostvaren niži prinos zelene krme za 38% zelene krme, ili suve materije za 30,9%). Gustina useva je imala su značajan uticaj na kvalitet suve materije
Gravity currents in a vegetated valley of trapezoidal shape
No full textIn this study lock-exchange experiments are performed in a tank of rectangular upper cross section and a lower vegetated valley of trapezoidal shape to study the effect of drag resistance, due to vegetation, on gravity currents. Many natural and man-made channels are approximately trapezoidal. For the simulation of the vegetation the bed is covered by flexible grass vegetation (height of vegetation, hv=2.0cm) of different submergence ratio hv/H (hv=height of vegetation, H=water depth). The motion of the gravity current is monitored with a digital video of high definition, the front velocity is measured and the height of the front is captured. Twenty four experiments are performed, twelve inside the trapezoidal section (H/Htr=0.4, 0.6 or 0.8) and twelve over the trapezoidal section (H/Htr=1.2, 1.4 or 1.6). The initial Reynolds number, based on the height of the valley and the reduced gravity, is greater than 10000 for all cases indicating that the gravity currents are turbulent. Results are compared with those of similar experiments without vegetation (Keramaris and Prinos, 2010) and hence the effect of the vegetation drag resistance on the motion of the current is investigated. The main conclusion of this study is that the shape of the tank plays a significant role in the propagation of gravity currents. The presence of trapezoidal increases the velocity of gravity currents in comparison with triangular or orthogonal shape
