Effect of Spraying with fenugreek Seeds Extract and Nitrogen on some Vegetative Growth Parameters of and Yield of Swiss Chard Beta vulgaris L. var. Cicla

Abstract

A field experiment was conducted in Al-Kufa city /Al- Najaf province during growing season of 2014-2015.The aim was to study the effect of spraying with Fenugreek seeds extract at three concentrations( 0 , 5 and 10 ml.L-1 ) and Nitrogen spraying with three concentrations( 0,50 and 150 mg. L-1 )on some vegetative growth parameters and yield of Swiss chard Beta vulgaris L. var. Cicle. Factorial experiment was used in Randomized Complete Block Design (R.C.B.D) with three replicates for each treatments and comparison was done using Duncan's multiples range test to compare means with probability level of 0.05 . The results revealed that spraying of fenugreek seeds extract with 10ml . L-1 had significantly increased plant height 48.90cm ,leave area 62.74cm2 and yield to 7.21ton.Hactar-1 .the nitrogen spraying with 150 mg . L-1 which increased number of leaves ,dry mater and nitrogen percentage to 12.81 leaf.plant-1,17.21 gm. plant-1 and 2.73% respectively ,while the interaction between the two factors increased most of the growth parameters .
