Seed dormancy is a genetically inherited trait whose intensity is modified by the environment during seed development and maturation. In order to study the effect of harvest time on the seed quality and optimum time of sowing to obtain good quality seeds, freshly threshed seeds of ten diverse rice genotypes harvested from six environments were evaluated for seed dormancy and seedling vigour ind...

Five bacterial strains with phosphate-solubilizing ability and other plant growth promoting traits increased the plant biomass (20-40%) by paper towel method. Glasshouse and field experiments were conducted using two efficient strains Serratia marcescens EB 67 and Pseudomonas sp. CDB 35. Increase in plant biomass (dry weight) was 99% with EB 67 and 94% with CDB 35 under glasshouse conditions. I...

to determine the effect of sowing dates (22 oct., 5 nov., 21 nov. and 5 dec.) on the green pod and dry seed yield of faba bean (vicia faba), field experiments were conducted using rcb design with four replications for three cropping seasons (1995-1998) at hashem abad research station in golestan province. result, of combined analysis of variance showed that 22 oct. and 21 nov. produced higher g...

the present research was conducted under laboratory and field condition to determine seed priming effects on maize inbred line's germination, emergence, and grain yield. seeds of two maize inbred lines include of mo17 (as paternal line) and b73 (as maternal line with cytoplasmic sterility) in the laboratory conditions were subjected to hydropriming for 12, 24, 36 and 48 h, or osmoticprimin...

Seed production of farmers preferred improved maize varieties under community based seed production(CBSP) group initiated in the hills of Nepal under Hill Maize Research Project in 2000. Trained members of the community group produce improved seeds identified through participatory varietal selection procedures. Despite quantum jump in maize seed production, 14 tons by 7 CBSP groups in 2000 to 1...

emergence of crops is affected by environmental factors such as soil water, salinity and sowing and seed quality. the present study was conducted to evaluate the effect of seed aging (seed quality) on emergence of wheat under optimum (control) and stressful conditions including salinity (2 levels), drought (2 levels) and deep sowing depth (physical stress). seeds (cv. ‘zagros’) were kept at a h...

Differential protection of plants by Enterobacter cloacae was studied by investigating early sensing and response behavior of Pythium ultimum sporangia toward seeds in the presence or absence of E. cloacae. Ten percent of P. ultimum sporangia were activated within the first 30 min of exposure to cucumber seeds. In contrast, 44% of the sporangia were activated as early as 15 min after exposure t...

in order to study the effects of on-farm seed priming and sowing date on germination percentage, germination speed, and some growth indices of three soybean cultivars, a field experiment was carried out in three replications using a split plot factorial in a randomized complete block design. main plots were representative of two sowing date (5th and 21th of may), while subplots included combina...
