Abstract
This study was conducted at the experimental field of the College of Agricultural Studies, Sudan University of Science and Technology -Shambat during winters of 1999-2000 and 2000-200 1. The study was performed to compare, agronomically and financially, the effect Of a locally- made partially acidulated phosphate rock (PAPR) from Jebel Kurun in Nuba Mountains of western Sudan to that of the imported triple superphosphate (TSP). The treatments tested consisted of two phosphorous (P) sources i.e. TSP and PAPR. A combination of the two sources and inoculation of the test crop (wheat) with mycorrhizae fungus were also tested. The treatments were applied at three comparable levels (43.0, 64.5 and 86 kg ha-1 P2O5 designated as 1P, 1 .5P and 2P) and arranged in a randomized complete block design. The residual effect of the P sources was also evaluated. Financial comparison between the different treatments was conducted. The results indicated that it is profitable to use PAPR of Jebel Kurun as a P source for fertilization at the rate of 258 kg ha-1 (64.5 kg P ,or by mixing with TSP at 15%TSP +85% PAPR at IP level, 25%TSP+75% PAPR at l.5P level or 50% TSP ± 50% PAPR at 1. 5P level.
الملخص
أجريت هذه الدراسة في حقل التجارب بكلية الدراسات الزراعية – جامعة السودان للعلوم والتكنولوجيا - شمبات، خلال شتاء (1999/2000م) و(2000/2001م). الدراسة أجريت للمقارنة المحصولية والمالية لتأثير سماد صخور الفسفور المحلية المحمضة (PAPR) والمستخرجة من جبل كورون بجبال النوبة–غرب السودان بسماد السوبر فوسفات الثلاثي المستورد (TSP). المعاملات التي اختبرت تضمنت مصدرين للفسفور (P) هما TSP وPAPR. خليط من المصدرين وتطعيم لمحصول الاختبار (القمح) بفطر (الميكرورايزا) أيضاً تم اختبارها. المعاملات أجريت على مستويات مقارنة ثلاث (43.0 – 64.5 كيلوجرام/هكتار مصنفة P2O5 - 1.5 P-2P) ونظمت على تصميم القطاعات الكاملة العشوائية. التأثير المتبقي لمصدر الفسفور تم تقويمه أيضاً. أجريت المقارنات المالية بين المعاملات المختلفة. وأوضحت النتائج أنه من المربح استخدام ااـ (PAPR) من جبل كورون كمصدر للفوسفور للتسميد بمعدل 258 كيلوجرام للهكتار (64.5 كيلوجرام (P2O5) للهكتار) أو بالخلط مع (TSP) بمعدلات ( 5% TSP - 85 PAPR بمستوى (1P))، (25% TSP-75% PAPR بمستوى (1.5P)) أو (50% TSP -50% PAPR بمستوى (1.5P)).
