Effect of Foliar Application of Zinc on Growth and Yield of Guava (Psidium Guajava L.)Advances in Science, Technology and Engineering Systems Journal (2016)
In depth study focusing to ascertain the effect of different rates of Zinc (Zn) fertilization in improving the quality and yield of Guava fruit was carried out at Gharo, Sindh – Pakistan during year 2014-15. The outcome of the research revealed that there was no significant effect on the yield as well as quality, without using foliar Zn fertilizers. However, after application of the arrangement of foliar fertilizer the quality and production of fruits was significantly increased. The fruit yield in terms of plant height (3.111 m), length of fruit (6.989 cm), breadth of fruit (6.070 cm), weight of fruit (111.555 gm), number of fruits per plant (379.679), fruit yield (41.935 kg/plant) was recorded maximum in plants which were treated with Zn5 (0.5%). Same treatment also showed the superior fruit quality traits evaluated in terms of TSS (9.373 %), Vitamin C (45.147 mg per 100 ml of juice), and Firmness (5.969 kg/cm2) with lower acidity (0.485 %). Nearly same results were achieved by Zn6 (0.6%) and Zn7 (0.7%) treatments but statistically some parameters recorded less. However, plants with no foliar application showed un-satisfactory results regarding all the parameters. Too low or high concentration of Zinc solution may reduced the yield and yield parameters of guava.
