Abstract
Wheat (Triticum aestivum L) crop production was evaluated under organic conditions during the year 2008-09 and 2009-
2010 at National Agricultural Research Center (NARC), Pakistan Agricultural Research council (PARC) Islamabad. The
study includes four treatments with four replications. The treatments includes; (1) Organic fertilizer 625 Kg ha-1
, (2) Organic
fertilizer 625 and Humic Acid 10 Kg ha-1
(3) Humic Acid and Sea weed extract 625 ml ha-1
and (4) Control. Organic
amendments were incorporated during land preparation and seaweed extract as foliar spray. The basal dose of organic
fertilizer and humic acid (granule) were added at the time of sowing of wheat during 2008-2009 and 2009-2010.Humic acid
solution 1% and sea weed extract were applied as foliar spray at 6 inches of wheat crop. The second foliar spray was done at
tillering while third and forth sprays at heading and milking stage respectively. The crop conditions, color, shoot length and
spike and yield parameters were recorded at different stages of the organic fertilizer application. The soils and crops managed
organically are sustainable. Similarly, biological and chemical properties of soil also improved significantly. The compost
enriched with different organic waste increased all physico-chemical and biological properties of the soil as well as yield of
the crop. The wheat crop morphological and agronomical parameters also increase significantly. Moreover, nutrients supply
and other soil properties like pH, CEC, ECe and plant nutrients including microbial community structure influence positively.
