to survey the effects of chemical and biological phosphorus on the yield and essential oil of satureja hortensis l. as an important medicinal plant, factorial experiment was conducted based on randomized complete block design with three replicates at research station of faculty of agriculture, urmia university in 2011. the treatments were chemical phosphorus fertilizer with four levels (0, 50, ...

A field experiment was conducted to determine the response of different doses of N and P2O5 on the growth and flower quality of gladiolus at farmer field district Quetta during the summer season 2008. Six treatments were included in the trial viz; T1 (125+100); T2 (125+200); T3 (150+100); T4 (150+200); T5 (175+100) and T6 (175+200) NP kg/ha were tested in four replicated randomized complete blo...

Whole-crop wheat (Triticum aestivum L.) as forage has been extensively used in the world. In this study, the effects of N application rates on the yields, nutritive value and silage quality were investigated. The N application rates were 0, 75, 150, 225, and 300 kg/ha. The research results indicated that the dry matter yield of whole-crop wheat increased significantly with increasing N rate up ...

A study was carried out on the optimal dose of inorganic fertilizer used in carp polyculture system over a period of 10 months. Three treatments were assigned: without inorganic fertilizer, with the application of 100 kg/ha/month inorganic fertilizer and 150 kg/ha/month inorganic fertilizer as T1, T2 and T3, respectively. Each treatment had three replications. The selected indigenous carp speci...

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...

Dry matter (DM) partitioning is function of the solar radiation intercepted by the crop canopy and their plant’s leaf area exposed within the canopy. Row orientation (RO) and Row-spacing (RS) within canopy influenced the leaf size and might be the light use efficiency. We, therefore, studied cob bearing leaf area and leaf-area-profile (LAP) of maize planted at different RO, RS and N-rates (0, 1...

abstract this study was carried out in farm of dehkhoda institute (2013-2014). the study was done as randomized complete blocks design with five potassium sulfate amounts (0, 50, 100, 150 and 200 kg/ha) and four replications. according to results, potassium affected the number of stalk numbers, yield, and the amount of obtainable sugar (p<0.01) and purity (p<0.05). the highest stalk numbers (18...

plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. in this study, field experiment carried out as factorial randomized completely block design (rcbd) in 3 replications. different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. second factor was different plant spaces (10, 15, 20 and 25 cm). results showed th...

Plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. In this study, field experiment carried out as factorial Randomized Completely Block Design (RCBD) in 3 replications. Different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. Second factor was different plant spaces (10, 15, 20 and 25 cm). Results showed th...
