Effect of time of grafting and scion varieties on success of graftage in guava (Psidium guajava)

The experiment was conducted at College of Horticulture and Forestry, Rani Lakshmi Bai Central Agricultural University, Jhansi, during 2019–20 to see the effect of time of grafting and source of scion on grafting performance in guava (Psidium guajava L.). Treatments comprised four time of grafting viz. T₁: 1^st fortnight of January, T₂: 2^nd fortnight of January, T₃: 1^st fortnight of February and T₄: 2^nd fortnight of February, and four different scion varieties viz Sj: Allahabad Safeda, S₂: L-49, S₃: Lalit and S₄: Shweta. Significant differences of time of grafting and source of scion were observed in different grafting and growth parameters. The maximum bud sprouting (97.8%) was noted in T₂S₂, 2^nd fortnight of January + L-49, which found at par with T₄S₁, 2^nd fort night of February + Allahabad Safeda (95.6%), whereas minimum bud sprouting was noted in T₁S₄ 1^st fortnight of January + Shweta (53.3%). The highest final survival (95.6%) obtained from T₂S₂ (2^nd fortnight of January + L-49) which was at par with T₃S₁ and T₃S₂, whereas lowest final survival was observed in 1st fortnight of January + Shweta (53.3%).
