Effect of foliar spraying of organic liquid fertilizer and micronutrients on flowering, yield-attributing characters and yield of banana (Musa paradisiaca) cv. Grand Naine

A field experiment was conducted to find out the effect of novel organic liquid and combi-F, grade-IV micronutrient on flowering, yield-attributing characters and yield of banana (Musa paradisiaca Linn.) cv. Grand Naine during 2014–15 and 2015–16 at Instructional Farm of ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari (Gujarat). The experiment was laid out in a randomized block design with factorial concept comparising two factors, viz. different levels of novel organic liquid fertilizer (0, 1 and 2%) and combi-F, grade-IV micronutrient (0, 1, 1.5 and 2%). The treatments were replicated thrice and applied 3, 5 and 7 months after planting. The foliar application of 1% novel organic liquid fertilizer was found better for getting maximum finger girth, length and girth of bunch, weight of third hand, fingers/bunch, number of hands/bunch, bunch weight and yield. While maximum finger length was reported with foliar application of 2% novel organic liquid fertilizer. However in case of micronutrient, foliar application of 1.5% combi-F, grade-IV micronutrient 3, 5 and 7 months after planting (F₃) gave maximum finger length, finger girth, length and girth of bunch, weight of third hand, fingers/bunch, number of hands/bunch, weight of bunch and yield.
