Application of Micronutrients for Augmenting Yield and Yield Attributes of Moong Bean (Vigna radiata)

Abstract

This experiment aimed to assess the impact of micronutrient application on primed mung bean (Vigna radiata). A field experiment was conducted at the Agricultural Farm of University of Calcutta, Baruipur, India (22°21′38″N 88°25′56″E). In this experiment, seven treatments, each with six replications were designed with a view to compare the production potential under different micronutrients application and also to find out the economic viability of this cultivar for soil quality. Maximum growth parameter, Plant height (53.56 cm), Number of branches per plant (6.45), yield attributes, grain yield (436.62 kg/ha), 1000 grains weight (34.43 g) obtained in P1i.e. slow release micronutrient-polyphosphate fertilizer (N:P:K:: 60:40:30 kg ha-1 and Zn: Fe: Cu: Mn :: 0.75: 0.263: 0.075: 0.15 kg ha-1). Only P1 treatment among other polyphosphate treatments has positive effect on yield of grains and so becomes statistically significant at the 1% level, over control and soluble ones. The increase in yield for P1treatment was 3.67% and it was also significant at 1% level with respect to S1i.e. soluble fertilizers (N:P:K:: 60:40:30 kg ha-1 and Zn: Fe: Cu: Mn :: 0.75: 0.263: 0.075: 0.15 kg ha-1). The increase in yield was 0.46% for P2i.e. slow release micronutrient treatment (N:P:K:: 60:40:30 kg ha-1 and Zn: Fe: Cu: Mn :: 0.50: 0.175: 0.05: 0.10 kg ha-1). with respect to S2 i.e. soluble fertilizers treatment (N:P:K:: 60:40:30 kg ha-1 and Zn: Fe: Cu: Mn :: 0.50: 0.175: 0.05: 0.10 kg ha-1). But, the yield for the P3treatment i.e. slow release micronutrient-polyphosphate fertilizer (N:P:K:: 60:40:30 kg ha-1 and Zn: Fe: Cu: Mn :: 0.25: 0.088: 0.025: 0.05 kg ha-1)  decreases with respect to S3i.e. soluble fertilizers treatment (N:P:K:: 60:40:30 kg ha-1 and Zn: Fe: Cu: Mn :: 0.25: 0.088: 0.025: 0.05 kg ha-1).
