in order to effects of sulfur and manure on grain yield, yield components, and some physiological traits of corn hybrid ksc 704 in calcareous soils of kermanshah province, a factorial experiment was carried out based on a randomized complete block design with three replications. sulfur fertilizer in four levels 0, 250, 500 and 750 kg ha-1 and manure in four levels 0, 4, 8 and 12 t ha-1 were app...

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 ...

A field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from July to December 2011 to evaluate the effect of variety and placement method of urea super granule (USG) on the yield performance of T. aman rice varieties. The experiment consisted of three aman rice varieties viz., Pajam, BR11, BRRI dhan40 and four placement...

Tillage practices significantly influences soil physical characteristics and crop productivity. The infiltration characteristics, bulk density, porosity, penetration resistance, grain yield of rice and wheat were measured under no-till without residue (NT), roto-tillage (RT), and no-till with residue i.e. happy seeder (HS) in rice-wheat cropping system in sandy loam (SL) and loamy sand (LS) soi...

Different winter barley cultivars showed various levels of genetic tolerance when they were exposed to different stress conditions. Therefore, investigations of interaction among genotypes (cultivars) and environments give useful information concerning yield stability and quality in barley (Blum, 1989; Ceccarelli et al., 1998, 2000; Lalić et al., 2007, 2009). Drought conditions frequently give ...

Small or shrivelled wheat kernels (screenings) that reduce crop value are commonly produced in terminal drought environments. The aim of this study was to establish whether the incorporation of the tiller inhibition (tin) gene would contribute to maintenance of kernel weight and reductions in screenings under terminal water deficit. Five Silverstar near-isogenic lines contrasting in high and lo...

The influence of crop residue amendments on the chemical properties of an acid soil and rice yields was investigated at Abakaliki for two cropping growing seasons (2006 and 2007). The residue treatments were rice straw, burnt rice husk and legume residue, while the rice cultivars were ITA 315, Ex-China and ITA 257. The design of the experiment was a 3 x 4 factorial in a Randomize Complete Block...
