in this study, the performance of different cultivation methods on sugar beet fields was evaluated. eight treatments were considered: a) use of a rolling cultivator twice during the growing season; b) use of a rolling cultivator three times during the growing season; c) use of a crescent cultivator twice during the growing season; d) use of a crescent cultivator three times during the growing s...

to determine the effects of different irrigation and salinity levels on qualitative and quantitative yield of sugar beet, an experiment was conducted for two years (2006-07)at torogh agricultural research center, mashhad, iran, using two sprinkler systems. each of the two irrigation systems was connected to two water sources with 1 and 6 ds/m salinity. irrigation was performed via two sprinkler...

Reactions o f photolytically generated SOJ with 2'-deoxyuridine-5 '-phosphate (5 '-dU M P), uridine-5 '-phosphate (5 '-U M P) and thym idine-5 '-phosphate (5'-dTM P) were studied by ESR spectroscopy in aqueous solution under anoxic conditions. From 5'-dU M P and 5 '-U M P the 5',5-cyclic phosphate-6 -yl radicals 10 and 11 were generated (pH 2 -1 1 ) whereas from 5 '-dTM P at .pH 3 8 the 5,6-dih...

this study was conducted in split plot design based on a randomized complete block design in naghadeh region, urmia, iran in 2009-10. two sowing patterns including a1) single row planting with 50 cm between-row spacing, and a2) two rows planting on the hill with 40 cm distance and 50 cm between-row spacing (40×50) were allocated to main plots and four furrow compactions including b1) control, b...

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from December 2004 to May 2005 to determine the most effective kind of trellis for the rice-cum-vegetable production system. The treatments consisted of five crop combinations viz. C0: rice alone i.e. control, C1: rice + bottle gourd, C2: rice + white gourd, C3: rice + ...

In this study, the effects of nitrogen fertilizer and plant growth regulator (ethephon) application on leaf chlorophyl, stem height and diameter, stalk yield, total sugar and bioethanol of sweet sorghum were determined. Four nitrogen treatments 0, 100, 200 and 300 Kg Urea ha-1 and four ethephon concentrations 0, 800, 1000, and 1200 ppm were applied on sweet sorghum in a split plot on randomized...

to determine the effects of pre-germinating of tubers and plant density on yield and some agronomic traits of six commercial potato cultivars, an experiment was carried out in ardebil agricultural research station for two years (2001 and 2002). the experiment was in a split split splot on the basis of completely randomized block design with three replications. pre-germination and non pre-germin...

to determine sugar content and root yield variation of new sugar beet hybrids under different irrigation levels, an experiment was carried out at zarghan agricultural research station offars agricultural and natural resources research center, shiraz, iran. the study was conducted as split block based on a randomized complete block design with three replications for two years, 2009-10, using lin...
