Abstract:
A study was conducted at date palm station that belong to Horticulture office of ministry of agriculture in Basra located in Hartha north of Basra during 2013 - 2014 season to find the the effect of the addition of the chemical fertilizer NPK+TE (20 - 20 - 20) and culture of legumes (alfalfa and broad been) around date palm trees cv. Sayer on chemical and physical characteristics during rutab stage. Fertilizers were added around tree trunk at depth of 25 cm and half diameter of one meter.Fertilizer were added at (0 , 250, 500 , 750, , 1000 ,1250 and 1500) gm / tree at two different time, the first one on 15/10/2013 and second addition on 1/3/2014.Alfalfa and broad bean were culture around trees on 1/10/2013. Results showed the significant effect of fertilizer at 1500 gm / tree level on most physical, chemical and productivity of fruits of cv. Sayer. The 1500 g m/ tree treatment wassuperior in its effecton flowering time, number of pollen spathes and fruit set. Pollen spathes first emergedand its number was 11 spaths and fruit set was 78.67% wheras ,control treatment delayed the emergence of spathsand number of spaths was six with fruit set 51.67%.The 1500gm/tree treatment was not significantly different from treatments of alfalfa and broad been culture and 1250 gm / tree treatments flowering date and fruit set ,also physical characteristics which were, fruit weight , mesocarp , seeds , fruit length , diameter, fruit size which were, 7.59 gm, 6.69 gm, 0.90 gm, 3.76 cm, , 4.47 m5.34 g were, results wheras,control treatment, respectively,3cm, 5.33 cm1.69 significantly , respectively and not 3m, 2.91 cm, 1.27 cm and 5.21 cm, 0.88 gmgdifferent fromalfalfa and broad bean culture and 1250 gm / tree treatment.For chemical characteristics which included moisture content , dry matter ,total soluble solids, total titrable acidity, total sugar, reducing sugar, sucrose and total protein in fruits also nitrogen, phosphorus and potassium in leaves where the 1500 gm /treet reatmentwas superior in those characteristics which were (29.29, 70.71, 65.17, 0.54, 61.61, 52.52, 8.64, 0.3, 1.88, 0.45 , 0.92)% respectively compaired to control treatment wheras,it was not significantly different from alfalfa treatment in total soluble solids and total titrable acidity and alfalfa , broad bean treatment and fertilizer at 1250 gm / tree in total and reducing sugar and different froma lfalfa and broad bean treatment in nitrogen percent and alfalfa treatment in phosphorus parcent.Summary الخلاصةThe 1500gm/tree treatment was superior compered to control treatment in ripening percent (69.33% ), bunch weight(6.82 kg) andtotal yield (40.92 kg) but not significantly different from alfalfa in ripening percent and alfalfa and broad bean treatmen and 1250gm/tree in bunch weight and total yield.According on the results of the current study, we recommend to use the NPK+TE fertilizer at 1500gm/tree or its interaction with alfalfa and broad bean culture to support growthand yield.
