  Field trials were conducted on black cumin (Nigella sativa L.), sprayed with either deionized water (control) or 10-5 M GA3 at 40 (vegetative stage) or 60 (flowering stage) Days after Sowing (DAS) to characterize the effects of hormone treatment on the mentioned parameters and select the suitable growth stage for spray in order to achieve desired results. Shoot length/plant, leaf number/plant, leaf area/plant, branch number/plant, dry weight/plant and accumulations of N, P and K were assayed at 70 DAS. Capsule number/plant, seeds capsule-1, 000 seed weight, seed yield q ha-1, harvest index and Seed Yield Merit (SYM) were analyzed at harvest (130 DAS). It was noted that growth, NPK accumulation and seed yield were maximal when spraying of GA3 was carried out at 40 DAS. However, spraying at 60 DAS was not much effective in terms of the parameters studied. Moreover, there was a significant difference in spray treatments at various growth stages only when GA3 was sprayed and not when water was sprayed.

  A research project "Side grafting and various scion parts interaction in guava" was carried out at Government Fruit Nursery Farm, Jabban, Dargai Malakand Agency during 2002-2003. Three scion parts i.e. Apical, Middle, Basal and two grafting methods i.e. side veneer and side T. grafting were studied. The experiment was laid out according to Randomized Complete Block design with two factorial arrangement. Maximum graft take success (77.5%), survival percentage (27.9) and percent saleable plants (97.6) were recorded in plants developed from middle scion part whereas minimum of these parameters were recorded by apical scion part. Significantly maximum scion length (99.0 cm) was by using basal scion part, In grafting methods, maximum scion length (81.8 cm), graft take success (75.0%), survival percentage (34.4) and percent saleable plant (95.7) were recorded in plant propagated through side veneer grafting. In interaction of various scion parts and grafting methods, Side veneer grafting using middle scion part resulted in better success and growth of guava.
