) and three plant species (Bougainvillea, Ixora and Rose); factorially combined and laid out in a completely randomized design with four repetitions. The results indicated that TS+SD medium gave significantly (P<0.05) higher number of roots and root lengths per plant while the least was with TS+PM medium. TS and TS+SD media were significantly higher than TS+PM medium in terms of root fresh weight and root dry weight per plant. Application of GA 3 at 100ppm compared to 0 and 200ppm concentrations gave significantly (P<0.05) better responses for all the root characters. The same trend was true for Bougainvillea compared to Ixora and Rosa. Hence, based on the outcomes of this experiment, combinations of TS+SD medium and GA 3 at 100ppm concentration are recommended for better root establishment, growth. and development in relation to the three plants under study.
A field experiment was conducted during 2014 and 2016 rainy season at Tudun Wada, Kano and Shika, Zaria in the Northern Guinea Savanna of Nigeria in order to study the physiological responses of maize hybrids under low nitrogen. The experiment consisted of two nitrogen levels 0 and 120 N kg ha−1 as main plot and 8 drought-tolerant maize hybrids and 2 controls as subplot laid out in a randomized split plot design and replicated three times. Physiological parameters of hybrids were significantly affected by low nitrogen at both locations. Interaction between hybrids and nitrogen was significantly affected at both locations. Based on these results, application of nitrogen significantly increased the physiological growth indices of maize hybrids. The extent of increment in physiological reactions was additionally higher in Zaria in view of higher soil natural carbon and nitrogen and higher precipitation was better dispersed at this area. However recent hybrids were more tolerant to nitrogen stress and out-yielded the older hybrids. Therefore the recently released hybrids were more adapted to abiotic stresses.
The increased demand for high quality mango in Nigeria requires for provision of qualitative fruits with superior characters. This could be achieved by grafting of cultivars with the desired qualities onto and adapted and available rootstocks. In view of a the demand deficit, two trials were conducted in 2015 rainy season at the Kano Institute of Horticulture screen house, Bagauda to study the influence of scion length, scion type and root-stock on epicotyl grafting in mango. Treatments consisted o and 10 cm), scion types (Alphonso, Julie and Mabrouka) and local rootstocks (Dankamaru and Gwaiwarrago). These were factorially combined and laid in a completely randomized design with three replicates. Results of the study revealed t successful in 8 and 10cm scions and these produced more leaves and longest grafted saplings. Alphonso and Gwaiwarrago were most compatible as they recorded the highest graft success. Experiments involving many scions and rootstocks is determine suitable combination of scion and rootstock for successful epicotyl mango.
The experiment was designed to assess the growth performance of improved cultivars of Mango grafted on adapted local morphological types. Two trials were conducted in 2005/2006 and 2006/2007 wet season at the teaching and research farm of Faculty of Agriculture, Bayero University, Kano (11 0 58'N and 8 0 25'E) situated in Sudan Savanna ecological zone of Nigeria. The experiment consisted of four morphotypes (Binta Siga, Gwaiwar Rago, Dankamaru and Fafaranda) factorially combined with three scions (Alphonso, Peach and Taymour) and laid out in a completely randomized design with three repetitions. The results showed that Binta Siga was identified as the best rootstock in terms of plant establishment probably due to production of higher number of roots, stem diameter, number of leaves, percentage take and general crop vigor. Taymour was observed to be the best scion in terms of compatibility with most of the rootstocks as expressed by its superior performance with regard to the characters mentioned earlier. Binta Siga is therefore recommended for use as rootstock by nursery men in Mango seedlings production for higher profit margin in Kano environment
Two pot experiments were carried out in the screen house of the Faculty of Agriculture Bayero University Kano (Latitudes 8 0 42 1 N and 9 0 30 1 N) during the wet and dry seasons of 2008/2009 to investigate the effects of Sowing Media and Gibberellic acid (GA 3) concentrations on the seedling establishment and growth of three ornamental plant species. The treatments consisted of three sowing media (Top soil TS, mixtures of Top soil plus Poultry manure TS+PM and Top soil plus Sawdust TS+SD) in the ratio of 2:1, three GA 3 concentrations (0, 100 and 200ppm) and three plant species (Bougainvillea, Ixora and Rose); factorially combined and laid out in a completely randomized design with four repetitions. The results indicated that TS and TS+SD gave significantly (P<0.05) greater number of days to bud break, leaf area, leaf fresh weight and leaf dry weight per plant. Application of GA 3 at 100ppm gave higher value of all the characters studied except number of days to bud break, where no significant difference was observed among the different concentrations. Bougainvillea was significantly (P<0.05) higher than the other plants in all the characters except days to bud break. The Combination of TS+SD medium and GA 3 at 100ppm concentration is recommended for the good growth and development of the shoot characters.
