| Abstract | ||
| The experiment was carried out in the fields of the Technical Institute in Mosul, the Nimrod location (limited rainfall area, average rainfall between 200 and 350 mm per year) by adopting local lentils variety to study the effect of planting dates (18 November and 27 January and 1 March) and interrow spacing (10, 20 and 30 cm) on the traits: plant height, number of main branches, number of secondary branches, number of pods.plant--1, 1000 seed weight(g) and seed yield kg.h-1 using the randomized complete block design of with three replicates for the two agricultural seasons 2016-2017 and 2017-2018. In both seasons, the results showed significant differences between the means of planting dates and their combination with the planting spaces for all traits, and the means of interrow spacing for the number of secondary branches, the number of pods.plant-- -- 1 and the seed yield kg.h-1. The late date of planting gave the best rate of seed yield and 1000 seeds weight, while the early date had a role in increasing the rate of growth characteristics (including plant height and number of secondary branches). The wide space between rows had the highest mean of the most traits, including the seed yield in both seasons. It was found that early planting in the wider space between the rows was better for the growth characteristics in both seasons, while the effect of the combination between the levels of factors varied on the productive characteristics and the most important one seeds yield as the variation of planting seasons, and this explains the significant role of environmental factors in changing the course of the effect of factors. A planting in late dates and at wider spaces are better for productive qualities. In general, planting in late dates and at wider spaces is preferable to productive traits. | ||
