Effect of Sowing date and seeding depth on germination, seedling differentiation of Chickpea seedling (Cicer arietinum. L)

Abstract

: The experiment  was carried out  at cereal technology lab, of crop science dopt, Faculty of Agricultural-  University of Omer AL-Mukhtar, , EL-Badia, Libya, during 2016- 2017, to study Effect of  Sowing date    ( 1^st February – mid February- 1^st march )  and seeding depth (2,4 and 6 cm) on the germination and seedling differentiation of Chickpea plant  , The experiment was laid out as factorial in randomized complete design with  three replication  used   The results revealed that

• sowing date1^st February had significant differences on all studied traits except germination percent  that  gave the least number of days for emergence  (6.33days), highest germination percentage (69,6 %), highest, germination vigor (645), gave the lowest number of days from sowing to completely rise of the 1^st  -2^nd,and 3^rd leaves , highest root and shoot length and seedling fresh weight.
• Results also indicated a significant  superiority of the 2 cm depth, as compared with  the other taro  depths for  initiation of germination and germination vigor characteristics of seedlings which  gave the least number of days to emergence (7.22days), highest germination percentage (67.8 %), , germination vigor (610) highest seedling length and fresh weight (13,56 cm and 3.29 g, respectively), and length  of seedling and root length                 (7.22 ,7.78cm) respectively .
• There was significant effect for the interactions between of sowing date 1^st February and the depth  of (2 cm)  which  gave the least number of days to emergence (07days), reported the lowest significant values for day to emergence (5.33days), gave the lowest number of days from sowing to completely rise of the 2^nd, leaf and also gave the highest fresh weight of seedlings stem and rootlet length.
