Pepper is one of the nutrition demanding vegetable. In order to compare N fertilizer uptake and plant numbers per area unit, an experiment was conducted with replications. In which fertilizer was the main factor and included Ammonium nitrate in 7 levels (0, 80, 160, 240 kg /ha-1) and 40+40, 80+80, 120+120 kg/ha-1 (in 2 stages i.e. Half of these amounts appliedpre planting ...
Nitrogen (N2) fixation is a major source of available N in ecosystems that receive low amounts of atmospheric N deposition. In boreal forest and subarctic tundra, the feather moss Hylocomium splendens is colonized by N2 fixing cyanobacteria that could contribute fundamentally to increase the N pool in these ecosystems. However, N2 fixation in mosses is inhibited by N input. Although this has be...
In order to study the effects of simultaneous application of nitrogen (N) and ZnSO4 fertilizers and biofertilizer (Azotobacter and Azospirillum) on grain yield and growth traits of rapeseed, Hyola308 cultivar, a field experiment, with split plot factorial layout based on randomized complete blocks design with three replications, was conducted at Research Field of Faculty of Agriculture, Univers...
This study was designed and conducted to investigate on physiological growth indices and photosynthetic pigments in three maturing corn (Zea mays L.) hybrids (SC704, SC500, and SC260) using four nitrogen (N) levels (0, 80, 160, and 240 kg N ha-1, from Urea, N= 45%). The experiments were conducted in Zabol and Isfahan in 2014 and 2015, respectively, using the split-plot arrangement in a randomi...
ABSTRACT- Declining land productivity associated with decreasing soil organic carbon and nutrients is a significant issue in monoculture production. The field experiment with different rates of fertilizer systems (60 kg ha-1 N + 100 kg ha-1 P, 300 kg ha-1 Bio-organic (organic fertilizer), 3 kg ha-1 Bioumik (biofertilizer), 30 kg ha-1 N + 50 kg ha-1 P + 150 kg ha-1 Bio-organic fertilizer and 30...
Two sesame cultivars (Sesamum indicum L.) were evaluated using various 3 different sowing dates (20 th June, 10 th and 30 th July) and four nitrogen levels (0, 40, 80 and 120 kg N ha -1 ) at the New Developmental Farm of The University of Agriculture, Peshawar, Pakistan during summer 2012. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangement using f...
In order to investigate the effect of source and rate of nitrogen fertilizer on yield and quality of sweet corn, a field study was conducted in 2011 cropping season in Agriculture Experiment Station of College of Agriculture, University of Guilan. A randomized complete block design with three replications was used. Treatment consisted of four levels of nitrogen fertilizer (0, 46, 92 and 138 kg ...
To increase grain yield, nitrogen use efficiency (NUE) and nitrogen apparent recovery fraction (NARF) in wheat (Triticum aestivum L.), an experiment was carried out in Karaj Soil and Water Research Station farm for two consecutive growing seasons in 2004-05 and 2005-06. The experimental design was RCBD with 6 treatments (T1= Control T2= 150 kg ha-1 of N as urea in 3-split applications T3= 1/3 N...
In order to investigate the effect of nitrogen (N) fertilizer and transplanting date (TD) on yield, yield components and stem lodging of rice (Oryza sativa), a two-year study (2007-2008) was carried out in Fozveh Research Station, Agricultural and Natural Resources Research Center of Isfahan, Iran, using split plots, based on randomized complete blocks design with three replications. Four N fe...
This study observed the yield response to nitrogenous fertilizer for a popular Boro rice variety BRRI dhan29 under silty loam texture soil with satisfactory organic matter (2.96%). Sequential elevated doses of nitrogen (N0, N70, N80, N90, N100, and N110 kg ha-1) along recommended phosphorus (P), potassium (K), Sulphur (S) significantly increased grain […]
