EFFECT OF LOCATION AND HARVESTING DATE ON YIELD AND 1,000-SEED WEIGHT OF DIFFERENT SUNFLOWER GENOTYPES

Vladimir Miklič; Jelena Mrdja; Reena Modi -; et al. FiVeR (Institute of Field and Vegetable Crops, Novi Sad, Serbia) 2012

Other claims from this paper (11)

Association Sunflower seed yield per head was higher in Serbia than India.
Association Sunflower 1,000-seed weight was larger in Serbia than India.
Observation Ha-121 had the highest seed yield per head.
Association Yield rose gradually to the midpoint of the harvest period.
Intervention effect Only the first three harvest dates gave significantly lower yields than later dates.
Observation Ha-121 had the largest average 1,000-seed weight.
Association Harvest date had a quadratic relationship with yield.
Association Some maximum yields occurred at seed moisture of at least 40%, especially in Serbia.
Association At both sites, 1,000-seed weight mostly rose linearly until the final harvest dates.
Observation Some genotypes could be harvested early without a major effect on yield or 1,000-seed weight.
Recommendation The authors advise accounting for the significant influence of location when scheduling early harvest.

Other claims from this paper (6)

Intervention effect Sunflower biomass decreased as irrigation water decreased.
Observation Sunflower seed yield ranged from 0.22 to 1.40 ton per hectare.
Intervention effect T4 produced the highest grain yield and T1 the lowest.
Intervention effect T1 and T2 did not differ significantly in seed yield.
Intervention effect At 65% and 100% ETc, biomass, stover and seed yield did not differ significantly.
Recommendation The authors recommend 65% ETc irrigation for sunflower in semi-arid regions.
