Abstract:
An experiment was conducted at the experimental field of Horticultural farm of
Sher-e-Bangla Agricultural University, Dhaka, during November 2014 to April
2015. Cell compatibility of tomato and potato by making pomato plants was
evaluated in six grafting combinations (tomato grafted on potato) and laid out
in RCBD design with three replications. Three potato (Solanum tuberosum L.)
and two tomato genotypes (Solanum lycopersicum L) were used for grafting in
all possible combinations. Two treatments, viz. two seedling age of tomato and
three fertilizer doses were used to identify best compatible grafting. The
compatibility was evaluated through the observation of yield and sixteen yield
contributing characters under different treatments. Cleft grafting was used to
assess the magnitude of different fertilizers doses effect on different pomato
genotype for high yield of tomato and tuber. The analysis of cell compatibility
revealed that the pomato G6 (BARI tomato-11 grafted on Asterix) showed the
best performance for total tuber yield (13.8 ton/ha) followed by pomato G3
(BARI tomato-2 grafted on Asterix) which showed the total tuber yield 9.27
ton/ha. Both the pomato genotypes for giving high tuber yield were grafted
with 25 days old seedling of tomato and the applied fertilizer dose was 390
Kg/ha of urea, 280 Kg/ha of TSP, 312 Kg/ha of MoP, 140 Kg/ha of gypsum
and 13000 Kg/ha of cowdung. The pomato G3 also showed the best
performance for total tomato yield (41.65 ton/ha) when grafted with same age
of seedling of tomato and with the same fertilizer doses as mentioned for total
tuber yield. Hence, pomato G3 (BARI tomato-2 grafted on Asterix) could be
recommended to the farmers for grafting and cultivation for total yield
including both potato and tomato when grafted with young tomato seedling of
25 days old and with the fertilizer dose of 390 Kg/ha of urea, 280 Kg/ha of
TSP, 312 Kg/ha of MoP, 140 Kg/ha of gypsum and 13000 Kg/ha of cowdung.
