introduction safflower) carthamus tinctorius l.) is a tolerant plant to water deficit due to long roots and capability for high water absorption from soil deeper parts. safflower can growth successfully in regions with low soil fertility and temperature. behdani and mosavifar (2011) reported that drought stress affect on yield by reducing yield components and agronomic traits. biofertilizer dur...

Poultry litter contains an abundance of nitrogen (N) and has been used to fertilize pastures and forage crops in western Arkansas for a number of years. The objective of this study was to determine the N-fertilizer value of preplant-incorporated fresh and pelletized litter in comparison to urea fertilizer applied before flooding rice at the fiveleaf stage. Studies were conducted on two silt loa...

in order to study the effects of nitrogen and drought stress on yield, yield components and seed quality of corn (hybrid single cross 704) a field experiment was conducted at agricultural research station in islamabad gharb in 2009. experiment design was split plots based on randomized complete block design with three replications. main plots included full irrigation requirement, 80 percent and...

management of soil fertility via biological fertilizers inoculation is one of the most important components based on sustainable agriculture. in order to investigate the effects of biological and chemical fertilizers on yield and some morphological traits of forage yield sorghum, a field experiment was conducted as factorial based on randomized complete block design with three replications at a...

Huge ex-coal mining land provides the soil for crop development, yet improvement is required. Fertilizer and organic matter application liming are standard practices to improve productivity. The integrated management (ICLM) package offers alternative technology increase growth yield. This study aimed evaluate an ICLM technological sweet sorghum production in land. of Bioguma 1 Agritan variety w...

effects of nitrogen fertilizer levels on agronomic efficiency (ea), physiological efficiency (ep), and recovery efficiency (er), in rice (oryza sativa l.) cv. khazar was investigated in a rcbd of three replications in a sandy soil in guilan province, iran in 2003. this study compared the effects of six n rates, namely: control (no n fertilizer), 40 (basal), 40+40 (basal + midtillering), 40+20+2...

Farmer in different parts of Ethiopia uses a similar type fertilizer and amounts that are below the crop requirements, even low soil fertility which limits production general. To solve over-blanket application over agroecology Ethiopian Soil Information System (EthioSIS) mapped recommended types for specific location. A NPSB where Beko village, but rate this was not studied so far. So, field ex...

To investigate the effects of organic fertilizers and irrigation frequencies on yield and quality of cherry tomato an experiment was conducted using six fertilizer doses including control (no fertilizer), NPK fertilizer (urea at 300 kg, TSP 200 kg and MoP 250 kg), cow-dung at 5 t ha-1, cow-dung at 10 t ha-1, poultry manure at 5 t ha-1 and poultry manure at 10 t ha-1 with two levels of irrigatio...

ABSTRACT- To evaluate effects of different soil moisture conditions namely, phosphorus (P) and zinc (Zn) application, on extractable Zn and Fe, two experiments were conducted in laboratory conditions based on a completely randomized design with a factorial arrangement of treatments with two replications. The first experiment was performed with the following factors; incubation time at four leve...
