Abstract

To analyze the plant establishment and vegetative growth of acid lime c.v. Vikram and to standardize the doses of different micronutrient combinations, an experiment entitled, “Effect of different micronutrient combinations on plant growth and plant establishment of acid lime (Citrus aurantifolia Swingle) c.v. Vikram” was carried out during the year 2020-2021 in an open field, Central Research Farm, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The experimental field was laid out in a Randomized Block Design (RBD) with 11 treatments of different micronutrient combinations and three replications. The levels of micronutrients included ZnSO4 (0.5%, 1%, 1.5%, 2%), FeSO4 (0.5%, 1%, 1.5%, 2%) and Borax (0.5%, 1%, 1.5%, 2%). The variety used in this experiment was Vikram. The experiment comprised 10 foliar applications by varying the concentrations of the above said micronutrients in combinations along with control. The experim

Conclusion

From the present investigation it may be concluded that T10 ZnSO4(0.5%) + FeSO4(0.5%) + B(2%) resulted in highest survival percentage and vegetative growth parameters like survival percentage (100% ), mortality per cent (0.00%), plant height (cm) (41.88), number of leaves per plant (102.99), number of branches per plant (15.48), stem girth (2.23cm), plant spread (64.76cm), leaf area (6.60cm2), Leaf area index (0.0026LAI) and chlorophyll (64.67SPAD). Moreover, the treatments T9, T5, T4, T3, T2 and T1 also showed 100% survivability due to higher zinc and boron content and lesser iron content and the other treatments including the control died mostly due to iron toxicity and environmental conditions. Hence, for better growth and establishment it is recommended to apply the foliar application of proper dose of micronutrients at initial stage of acid lime seedlings under Prayagraj agro-climatic conditions. Since this is based on one season trail therefore, further evaluation trai
