Influence of Organic and Inorganic Fertilizers on Soil Nutrients Availability and Wheat Productivity.

Abstract

Soils degraded physically and nutritionally due to continuous use of chemical fertilizers under intensive agricultural. Management of N is the key for sustainable and profitable wheat production in a low N-soil availability. So a field experiment was conducted on a clay soil using wheat (Triticum aestivum) Giza 168 variety during 2008 / 2009 season at Agricultural Experimental Station of Fac. Agric, Mansoura Univ., to study the influence of combined use of mineral fertilizers (urea) and organic fertilizers in the form of farmyard manure (FYM), composted rice straw (CRS) and their combinations on wheat productivity, nutrients availability and monitoring soil organic matter (SOM) status in soil at certain times 45, 88 and 155 days from wheat planting. The randomize complete blocks design with three replications was used. The mineral fertilizer (urea) was applied at the rate of N1=60 and N2=120 kg urea fed-1 .The amounts of various organic fertilizers used were (10 and 20 m 3 fed-1), for both FYM and CRS. Organic fertilizers added either alone or in combinations with urea to the soil. Results indicated that the maximum increase in grain yield (54.66 and 56.55 % over untreated control) and straw yield (1660.50 and 1710.99 g.m 2) were recorded with N2FYM2 and N2CRS2 respectively. All combination of organic (FYM or CRS) and inorganic fertilizers gave the optimum availability of NH4 + , NO3-, P, K concentration in soil beside the enhancement of soil organic matter percentage (SOM) as compared to the other treatments.

Importance of Organic Manuring and Mineral Fertilization for Wheat Yield and Its Components in El-Dakahlia Governorate .

“…This is might attributed to the integrated use of inorganic fertilizers with organic manure sustains higher crop yield, maintain soil health and gave the optimum availability of NH 4 + , NO 3 -, P, K availability microelements . These results are confirmed with those obtained by Hammad et al, (2006) , Hammad et al (2011) and Naeem (2006…”

Effect of Fertilization and Foliar Applicaion Treatments on Coriander Plant (Coriandrum sativum L.)

“…of branches and umbels plant -1 (90.64 cm, 6.52 branches and 24.62 umbels) were recorded in the first season by using FYM at the rate of 30m 3 fad -1 . The superiority of plant treated with ( CP) is may be due to its high contains organic matter and nutrients than (FYM) according to our analyses before planting (Table 2)and this finding are in agreement with Hammad et al(2011) who reported that compost is considered an excellent source of organic matter and addition of compost will increase soil organic matter levels more quickly than another manures and slurries .Also these results are in harmony with the finding of Abdou et al,(2015) who revealed that vegetative growth characters of coriander plant were significantly increased due to the application of all levels of compost. NPK, Bio-Fertilizer and Foliar applications effect.…”

Effect of Organic Manure and Phosphorus Fertilization on Wheat Crop in Salt-Affected Soils.

“…1-.These findings are in agreement with those obtained by Singh and Agrawal, (2005) who reported that application of 10 and 20 tones ha -1 FYM increased the grains yield and the total N P and K uptake in wheat crop. Also, Hammad et al (2011) found a positive effect of organic fertilizers on soil nutrients availability and wheat productivity.…”
