Quality Evaluation of Different Forms of Compost and Their Effect in Comparison with Inorganic Fertilizers on Growth and Yield Attributes of Wheat (Triticum aestivum L.)

Abstract

The core objective of conducting the current study was to evaluate the chemical compositions of different composts and their effect on wheat yield. Mineral matter content, ash and moisture were higher in all enriched composts and vermicompost in comparison to conventional compost whereas as total organic carbon, water soluble carbon and C:N ratio were higher in conventional compost.There was higher variation in the content of nutrients in different composts as that of the conventional one but nitrogen and phosphorus were higher in nitrogen enriched phosphorous-compost and phosphorous enriched vermicompost. Zinc was higher in nitrogen enriched phosphorous-compost, vermicompost and phosphorous enriched vermicompost whereas manganese was higher in vermicompost and phosphorous enriched vermicompost. Biochemical quality stated that conventional compost had lesser amount of total phenol, alkaline and acid phosphatase enzyme activity but higher dehydrogenase activity than those of enriched composts. The more dehydrogenase activity in conventional compost is an indicator of partial decomposition. The time period of decomposition was almost similar (120 ± 5 days) among the enriched composts, whereas in case of conventional compost, decomposition period was 160 ± 10 days.Crop yield was lower in conventional compost but highest yield was obtained by supplying nitrogen enriched phosphorous-compost and phosphorous enriched vermicompost, nitrogen enriched phosphorous-compost provided yield at par to inorganic fertilizer application at 90 kg ha -1 N, 20 kg ha -1 P and 20 kg ha -1 K.

Effect of Nitrogen Fertilizer Application Dates on Growth and Yield of Six Wheat Cultivars (Triticum aestivum L.)

“…The results also indicate that there were significant differences among the cultivars as Rasheed gave the highest rate of the weight of 1000 grains 38.89 g compared with Abaa 95 which gave the lowest rate (26.56 g) with an increasing rate of 46.42%. The reason of these results could be caused by the genetic differences among wheat cultivars and these results were mentioned previously by (Hussain, Shah, Hussain, & Iqbal, 2002)and (Johari, Qasimov, & Maralian, 2010). The result of the table (7) showed that there were significant effects of nitrogen fertilizer addition dates, the cultivars, and their interaction on grain yield.…”

Evaluation of Different Composts Composition on the Yield and Yield Components of Maize (Zea mays L.)

“…Application of poultry manure @ 2.50 t acre -1 with mineral 200-150-125 kg NPK ha -1 produced more grain yield (7.74 t ha -1 ) as a result of enhanced ears plant -1 , grains ear -1 and 1000-grain weight. There was higher difference in the content of nutrients in various composts (Hussain et al, 2015). Wheat residue performance was poor as compared to other residues (Kamakar et al, 2014).…”

Exploring selected plant nutrient in compost prepared from food waste and cattle manure and its effect on soil properties and maize yield at Wondo Genet, Ethiopia

“…Compost prepared by mixing cow dung with paddy straw showed higher total organic matter, C/N ratio, but higher phosphorus, nitrogen, zinc and manganese for composts enriched with nitrogen or phosphorus (Hussain et al 2015). On other hand, the compost enrichment with urea, phosphate, zinc, iron, copper and manganese at various stages of composting in chaffed cotton stalks and farm wastes reduced C/N ratio, and lignin but increased other nutrients Chari and Ravi (2013).…”
