Effect of two growing seasons on growth, yield and its components of lentil varieties under rainfall condition in north of Iraq
Abstract
The investigation was conducted at Bakrajo in Sulaimani Province at two seasons (2011-2012 and 2012-2013) to select the best varieties for growth and yield characteristics of lentil that adapted to the environment of Sulaimani province. Eight lentil varieties were utilized in the study. The experiment was designed as a Randomized Complete Block Design (R.C.B.D) with three replications. Mean comparison was carried out by the least significant difference (L.S.D) at a significant level of 5%. The result confirmed the interaction between average seasons and varieties on some growth and forage characteristics for the two seasons. Consequently, the highest value for the characters; plant height with 36.33, days to %50 flowering with 118.33, and days to maturity with 152 were realized by the varieties V.3, V.7, and V.5 consecutively. The characters, number of branches.plant-1 with 3.33 for the variety V.1, first pod height with 15 for variety V.6, and variety V.3 for no. of branch nodules.plant-1 with 36.677. In the 2012-2013 season, variety V.5 gave the maximum value for plant height with 44 cm, days to %50 flowering with 121.66 days for the variety V.3, days to maturity with 161 days for the variety V.8, no. of branches with 19.33 for the variety V.5, and no. of bacterial nodules/plant for the variety V.3 with 31.66. Effect of the interaction between seasons and varieties on seed yield and its components for two seasons. The variety V.2 produced the highest seed yield and some of its yield components for both seasons. The effect of seasons showed that in season 2011-2012 gave the maximum values for all characters of growth and seed yield components for lentil varieties except for no. of seeds/pod and no. of seeds/plant.
