line no. 4 was selected from local champ a rice of lord egan, based on pure line selection method, during 1992 to 1995. the mean yield of this line was 6342 and 6829 kgha-l in two regions of lord egan in 1996 to 1997. the yield of this line was 700-1500 kgha-l more than that of lord egan local rice. line 4 is more early maturing than the local rice with better marketability and quality. amylase...

scarce water resources is a worldwide problem, still for iran, a country predominated by an arid and semi-arid climate, water limitation is more severe than for many other areas of the world. a field experiment was conducted to investigate the impact of irrigation regimes on growth, grain yield and irrigation water use efficiency in maize (zea maize l.) in 2006 at the research farm, college of ...

yekta was created in 1981 from crossing between b5 ? m7 and an early maturing palistinian line, in oil seed crops research department of seed and plant improvement institute (spii) at karaj. the pure line of the cross was obtained after five years of selection with pedigree method. preliminary evaluation of the line along with other 31 selected lines was done in 1989 and yekta together with oth...

abstract soil crust decreases soil infiltration and prevents plant stablishment. thus reduction of crust effects is a prominent way to avert desertification. this study was conducted to investigate the effect of polyacrylamide on emergence of canola seedlings in a crusted soil and some physicochemical properties of soil such as ph, ec, sar and bulk density in a field located in date and tropica...

introduction of a suitable vetch as winter crop in cold drylands of iran is highly important. line vp-2670 with origin of turkey was selected from icarda nursery during 2002 and was evaluated along with other selected lines and local checks over nine years in different stations and on-farm conditions. vp-2670 with mean 3500 kgha-1 dry biomass over environments, high stability and protein conten...

Vermicomposts processed commercially from food wastes and paper wastes were applied, to 4.5 m(2) field plots, under high plastic hoop tunnels, at rates of 5 or 10 tha(-1) to evaluate their effects on the growth and yields of strawberries (Fragaria ananasa) var. 'Chandler'. The vermicomposts were incorporated into the top 10 cm of soil and supplemented, based on chemical analyses, with amounts o...

We studied the suitability of municipal solid waste compost (MSWC) application to submerged rice paddies in the perspective of metal pollution hazards associated with such materials. Experiments were conducted during the wet seasons of 1997, 1998 and 1999 on rice grown under submerged condition, at the Agriculture Experimental Farm, Calcutta University at Baruipur, West Bengal, India. The treat...

Many methods are available to monitor nitrogen content of rice during various growth stages. However, this monitoring still requires a quick, simple, accurate and inexpensive technique that needs to be developed. In this study, Tetracam Agriculture Digital Camera (ADC) was used to acquire high spatial and temporal resolution in order to determine the status of nitrogen (N) and predict the grain...
