تأثير مواعيد الزراعة و الأسمدة العضوية في نمو و حاصل و إنتاج المركبات الفعالة للخرشوف

Abstract EN

A field experiment was carried out at the Experimental Field of Hort.

Dept/ College of Agric.Abu- Ghraib/University of Baghdad during the growth season of 2008-2009, to study the effect of date of planting and organic fertilizer on plant growth, yield and production of active compounds in artichoke.

The treatments included three dates of planting; 1/10, 20/10, 10/11/2008 and levels of fertilizers; control, recommended chemical fertilizer.

,humic(high K) foliar spray + adding to the siol, poultry manure 20 ton/ha + humic (high K)spray, poultry manure 40 ton/ha+ humic(high K)spray.

A spilt plot design was implemented with three replicates .

The results showed that planting on 1st.oct.

increased plant height, number of branches, leaf area, number of heads, head weight, total yield, and total cynarin which were 135.6 cm, 7.2 branch, 259.4 dcm2, 11.4 head, 44.0 g, 5.0 ton/ha and 622.0 g/ha respectively.

The planting on 20,10/oct.increased the percentage of inulin and cynarin up to 4.8,4.7 mg/g for the first planting date and 520.7, 441.9 mycrogram/g for the second planting date.

fertilizing treatment increased vegetable and flower growth in application of poultry manure 40,20 ton/ha with spray humate which were 123.1,121 cm, 6.9,6.1 branch, 237.3,215.5 dcm2, 10.1,9.1 head 44.3,43.4 g/head, 4.4,4.0 ton/h.

respectively .The poultry manure 20 ton/ha + humate resulted highest percentage of inulin ,cynarin and cynarin yield 5.6mg/g 648.2 mycrogram/g, 806.8 g/ha respectively.

The interaction treatment of poultry manure 40 ton/h + with spray humate at the 1st.oct.

increased plant height, number of branches, leaf area, number of heads and total yield 152 cm, 8.3 bran, 302.5 dcm2, 14.9 head and 6.6 ton/h respectively.

While the highest inulin percentage and the percentage and cynarin yield in the heads 6.4 mg/g, 1036.1 mycrogram/g,1481.1 g/ha was found in plants manured with poultry manure 20 ton/h + with spray humate at the 1st.oct.
