dc.description.abstractThe present investigations “Studies on the effect of pre-sowing treatment and time of wedge grafting on production of saleable grafts in mango” were carried out in the nursery block of Fruit Science Department. The study was conducted using wild mangoes seeds. In the first experiment, total number of seeds were divided in 2 equal halves, one half of seeds were sown with intact seed coat (K1) while, in other half the mango kernels were extracted (K2), both type of seeds were then soaked in 6 different chemicals of varying concentrations viz. C1- KNO3 @ 0.5%, C2- KNO3 @ 1%, C3- KNO3 @ 1.5%, C4- BA @ 50 ppm, C5- BA @ 100 ppm, C6- GA3 @ 100 ppm, C7- GA3 @ 200 ppm, C8- beejaaumrit @ 2%, C9- beejaaumrit @ 3%, C10- panchgavya @ 2%, C11- panchgavya @ 3% for 12 hours and C12- Control. In the second experiment, the mango rootstocks were wedge grafted with scion on 7 different dates viz. T1-first fortnight of August, T2- second fortnight of August, T3- first fortnight of September, T4- fortnight of February, T5- first fortnight of March, T6- second fortnight of March and T7- first fortnight of April. The germination and vegetative parameters were observed. The results of study revealed that in first experiment, extracted kernels pre-soaked with GA3 @ 100 ppm produced earliest germination, 50 % germination, high rate of germination, germination percentage, number of leaves, maximum leaf area, highest seedling vigour index, while, on pre-soaking extracted kernel with KNO3 @ 0.5% reported in production of maximum seedling diameter. In second experiment, plants grafted on first fortnight of August recorded the earliest bud break, higher graft success rate, survival percentage, total plant height, number of leaves, number of branches and scion diameter, whereas, plants grafted on the second fortnight of August recorded maximum internodal distance. However, maximum diameter of rootstock was recorded in mango plants grafted on the first fortnight of September.en_US
