Effect of cytokinin and boron on growth and yield of mung been

Abstract

A Field study was conducted during spring season of 2015. at the field experiments in the field crops science department in Jadiryya – University of Baghdad, to study the effect of spraying three concentrations of Boron (0,250 and 500 mg B L-1) and three concentration of cytokinin (0,50 and 100 mg CK L-1) on growth and seed yield of Mung Been. Asplitpiot arrangement in randomaized complete block design (R C B D) with three replicates was used. Result showed that concention of cytokinin have significant effect on all studied traits. 100 mg CK L-1concentnetion of cytokinin gave shorter plant (56.48 cm) higher number of braches per plant (11.89) higher, number of days from sowing to maturity (92.11), fertility percentage (82.80%), number of pods per plant (81.23), number of seeds per pod (10.24 seed), protein percentage in seed (%29.36) and seed yield (1254.5 kg ha-1). Boron concentrations affected most of studied traits , 500 mg B L-1 of Boron gave higher number of branches per plant (10.11), higher number of days from sowing to maturity (89.22), fertility percentage (82.45 %), number of pods per plant (78.36), number of seeds per pod (10.56), and seed yield (1262.8 kg ha-1). Result showed that Cytokinin and Boron interaction have a significant effect on some triats. Cytokinin with 100 mg CK L-1 and Boron of 500 mg B L-1 gave higher effect on number of days from sowing to maturity (92.33), number of pods per plant(88.17), number of seeds per pod (10.83), and seed yield (1452.2 kgha-1
