Compost and sewage sludge contain high concentration of plant nutrients and, thus, have been used extensively as an inexpensive fertilizer. The objective of this study was to evaluate cumulative and residual effects of compost, sewage sludge and cow manure on nitrogen, phosphorus and potassium in soil and wheat. The experiment included compost, sewage sludge and cow manure, each applied at 3 ra...

Tuberose (Polianthes tuberosa L.) is an important commercial cut flower that has a short vase life. An experiment was carried out by using five different levels of humic acid (HA) (0, 25, 50, 75, and 100 mg L-1) and seven different levels of silver nano-particles (SNP) (0, 0.5, 1, 2, 3, 4 and 5 mg L-1) mixed with 1.5% sucrose on cut tuberosa cv. Single flower. The loss of fresh weight on third ...

In order to investigate the effect of chemical and biological nitrogen fertilizer on canola, a field experiment was conducted as a split plot based on a randomized complete block design with three replications at the research station of the Faculty of Agriculture, Yasouj University, located in Deshtrum region, in 2019. The main factor consisted of nitrogen fertilizer (zero, 25, 50, 75, 100 and ...
A field experiment was carried out at SCDA Pitești, on an Albic Luvisol with a 25.0-25.2% clay content, soy crop, Raluca TD variety. Seeds were treated Bradyrhizobiumjaponicum, the density 45-50 germinable grains/m2, and distance between rows 50 cm. Fertilizers applied during vegetation cycle as follows: Dual 1 liter/ha, Décor 0,5 liters/ha, Pulsar liter/ha. The experimental design included 12 ...
An experiment was conducted at the research farm of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh, during November 2013 to April 2014 to determine the growth and yield performance of four varieties of black cumin (Exotic variety, BARI kalozira-1, Faridpur local and Natore local) as influenced by three levels of fertilizers ...
Ischaemum rugosum is a competitive weed in direct-seeded rice systems. Developing integrated weed management strategies that promote the suppression of weeds by crop density, cultivar selection, and nutrition requires better understanding of the extent to which rice interferes with the growth of this weed and how it responds to resource limitation due to rice interference. The growth of I. rugo...
Solarization of field soil through mulching with transparent polyethylene sheets alone and in integration with farm yard manure (40 T/ha) and/or metalayl (25 kg/ha) during summer 1994-95 for five weeks in Isfahan resulted in an increase in temperature of 10 °C (± 1) and moisture preservation of up to 82%. Solarization effectively reduced foot-rot of cucumber (Phytophthora drechsleri) in the abo...
In order to study effect of plant density on yield and seed yield components of forage vetch in rain-fed and supplemental irrigation conditions, two separate experiments were conducted at the research filed of faculty of agriculture, Lorestsn University, during 2008-2009. Three species of forage vetch (Vicia narbonensis, V. sativa and V. dasycarpa) and in three plant densities (100, 150 and 20...
