Conventional seedbed preparation for spring sown crops in Sweden includes 3±4 harrowings followed by sowing, but there is a great interest among farmers to reduce this tillage. Since the soil is normally at ®eld capacity after winter, the conventional system implies a major risk of soil compaction and the farmer has to wait for the soil to dry before seedbed preparation can be started. A new te...

proper sowing date along with providing normal growth rate in rape oilseed plants significantly leads to higher seed and oil yield via decreasing cold damages. the experiment was conducted as factorial with two factors including sowing dates with 4 levels (12 and 23 september, 2 and 12 october) and genotypes with 5 levels (modena, licord, okapi, opera and zarfam) in three replications. the stud...

to investigate the effects of sowing date (sd) and single irrigation (si) on grain yield of rainfed wheat varieties, this experiment was conducted as split-split plot arranged in a randomized complete block design (rcbd) with three replications from sep.2000 to sep.2004 at the main station of dryland agricultural research institute (dari) in maragheh. the treatments included three sowing dates ...

Eight spring wheat cultivars were evaluated under three heat stress conditions (early, late and very late) in order to identify suitable cultivars to develop heattolerant genotypes resistant to future global warming. Results from the study indicate that stress did not negatively affect flag leaf area in ‘Prodip’ and ‘Sufi’, flag leaf dry matter partitioning in ‘Prodip’, ‘BARI Gom-26’ and ‘S...

A study was conducted to check the effect of different sowing dates and row spacing on the growth, seed yield and quality of offseason pea (Pisum sativum L. cv. Climax). Significant differences were recorded among sowing dates for days to germination while nonsignificant results were found for row spacing and interaction (A × B). Maximum days to germination were recorded in D1 (20 th April) and...

Sowing date and density are two important factors in produce of coriander. A field experiment was conducted with treatments: sowing time (5 May, 20 May, 4 June and 19 June 2009) and plant density (10, 30, 50 and 70 plants m). The experimental plots were laid out in a factorial according to a RCBD with three replications. Results showed that the effect of sowing dates and densities were signific...

In the Mediterranean zone, efforts to optimize combinations of supplemental irrigation (SI ), improved varieties, nitrogen (N ) and sowing dates aim to improve and stabilize cereal yields and maintain quality, especially for durum wheat. Thus, a 4 year field study (1992/1993 to 1995/1996) on a deep clay soil in northern Syria assessed the impact of SI (rain-fed, 1/3, 2/3 and full SI ) combined ...

The effect of different pre-sowing seed treatments and sowing dates on germination and rootstock quality of ber was assessed to standardize a combination which could yield optimum germination and quality rootstock. Of the fourteen pre-sowing treatments, highest seed germination and best seedling growth was obtained in T10 x D2 (seed soaking in water for 48 hours followed by 6 days storage in mo...
