EFFECT OF SPRAYING NUTRINT SOLUTION (Prosol) AND ALGAE EXTRACT ON GROWTH AND YIELD OF CAULIFLOWER (Brassica a a oleracea var. botrytis) UNDER DRIP IRRIGATION SYSTEM

Abstract

This study was carried out during winter season of 2017 at experimental field of Horticulture and Landscape Department - College of Agriculture- Al Qassim Green University. This experiment was aimed to study the effect of foliar spray with nutrient solution ( prosol) and algae extract in growth and yield of cauliflower. This experiment was designed according to (R.C.B.D) with three replicates and two factors. The first factor includes nutrient solution (Prosol ) in three levels ( Zero, 1.5 , 3) g.L-1. the second factor was the algae extract in three levels (Zero , 1.5 , 3 ) ml/L-1. Using foliar spray with nutrient solution (prosol) and algae extract has showed a significant effect in growth and yield characteristics . The treatment (3g.L-1 Prosol and 3ml.L-1 algae extract) was recorded higher average in the chlorophyll content , diameter of crud, weight of curds , Perimeter of curds, Total yield, percentage of nitrogen and potassium ( 70.87 SPAD, 19.33cm , 0.695 kg , 65.33 cm , 23.18 ton. hectare-1 ,2.51% ,2.75% ) as compared with control treatment which recorded the lowest rate ( 59.00 SPAD, 14.67cm , 0.418 kg , 48.00 cm , 13.92 ton. hectare-1 , 1.21% , 1.89% ) respectively. While the treatment (3g.-1 Prosol and 1.5ml.L-1 algae extract) gave the highest rate of number of leaves per plant , total plant weight and phosphorus percentage (23.33 leaf, 1.443 kg , 0.265%) as compared with control treatment which recorded the lowest rate percentage (16.00 leaf, 0.867 kg , 0.098%) respectively.
