Abstract: | Camelina (Camelina sativa L.) is famous for its oil quality and unique
fatty acid pattern. Growth and yield of crops reduced under water deficit conditions. Environmental threat such as drought or water deficit condition is the emerging problem which creates the negative impact on the growth of plants. Based
upon the current situation a pot study was performed in rain out-shelter to explore
the effect of different plant densities (15, 10 and 5 plants per pot) on growth and
seed yield of two camelina genotypes under normal (100% WHC) and water deficit (60% WHC) conditions by using completely randomized design with factorial
arrangement having three replicates. Results indicated that individual effects of
plant densities and water deficit stress levels considerably influenced the growth
and seed yield of camelina but interaction effects did not indicate any significant
variation. Maximum values of leaf area index (LAI) and crop growth rate (CGR)
were recorded in P3 treatment (15 plants per pot). However, maximum values of
leaf area duration (LAD), net assimilation rate (NAR), yield and yield components were observed in the treatment P1 (5 plants per pot). Water deficit condition
(60% WHC) significantly minimized the growth, seed yield (0.82 g/m2
) and yield
components of camelina genotypes. Both camelina genotypes (611 and 618) did
not differ significantly under water deficit conditions. |
