P
otato (
Solanum tuberosum
) is one of important crop grown all over the world due to its wider adaptability and staple food
of many nations. It contains valuable quantity of protein and energy per unit area as compared with rice and wheat, thus it
has more value than other crop as staple food. Plant breeders continue to evolve tuber varieties for high yielding environment
which are heavily dependent on the high doses of the inputs. However, continues rise in the input especially fertilizer prices
restrict their uses and farmers cannot support the crop with optimum doses of fertilizer. The symbiotic nitrogen fixing bacteria
has been considered as another way to supply the atmospheric nitrogen for the host and subsequent crop. The leguminous
species such as
Trifolium alexandrinum
are poor plant competitor and fix the nitrogen in the soils which may impart beneficial
impact on the exhaustive crop like potato. The present study was carried out to check the impact of intercropping on tuber
yield, its components and to screen out high yielding tuber lines under contrasting intercropping regimes. Data was analyzed
in completely randomized design with three replications under factorial arrangement. Overall, there was positive effect of
intercropping over the tuber yield of the breeding populations. Intercropping led to the 18% increase in tuber yield. Moreover,
there was also subsequent increase in various yield components. Correlation analysis showed that tuber weight per plant had
significant relationship with all traits except number of tubers per plant, chlorophyll contents, harvest index and leaf area under
intercropping regime. Berseem weight had negative relationship with tuber weight per plant. The correlation analysis showed
the importance of tuber diameter under both regimes.
