Influence of date palm wastes fertilization on some growth and yield of cucumber parameters under protected cultivation

Abstract

This study was conducted during spring season 2016 in plastic houses of horticulture department College of agriculture–Baghdad University (abu ghraib) alternative site for Anbar University in nonheated plastic houses. To evaluate effects of using organic fertilizer with date palm waste (grinder) date palm leaf and seeds date on growth and yield for Hybrid cucumber F1 Reem ccompared with the chemical fertilization. The treatments include T1 Control treatment fertilizing, with recommended chemical fertilizer, T2 2.5% fertilizing with, date palm leaf waste , T3 5%, T4 7.5%, T5 10% grindery seed date palm fertilizing with T6 1%, T7 2%, T8 4% and T9 2% grindery + 5% palm leaf waste. Treatments were distributed randomly according to (C.R.D) Completely Randomized Design, used and all data were statistically analyze and the means of, treatments were examined by L.S.D (P>0.05), The results were Treatment outweigh T8 recorded the highest average number of fruits reached 85.7 fruit plant-1 and fruit weight average 98.56 gm. fruit and higher average for plant yield records 8.436 kg plant-1 and It recorders lowest nitrate in fruit 0.4600 mg-1gm were T8 (4% date seeds wastes) records high result of leafs area was 67.4dcm2 and in leaves contains of chlorophyll records 92.80 spad unit plant heights records 253.6 cm and the same treatment. T8 outweigh average of nitrogen rates in leaf records 1.2867% and height of phosphor in leafs records 0.3733% and higher potassium rates in leaf records 1.7567%, On the other hand outperformed organic fertilizers waste of date seeds in recipes vegetative growth and yield compared to chemical fertilizer.
