Effect of organic and inorganic fertilizers on penology of Maize varieties

Abstract

The performance of organic and inorganic fertilizers have shown positive effects on plant growth in crop production, a study was conducted to measure the effect of various levels of organic and inorganic fertilizers in maize. The experiment was conducted in randomized complete block design with split plot arrangement having three replications at New Development Farm, Khyber Pakhtunkhwa Agricultural University Peshawar during kharif 2009-10. Various organic fertilizers namely, (1) Higo plus (500 kg ha -1 ), farm yard manure (10 tons per hectare) both were incorporated in the soil before sowing (2) Mexicrop (500 liters in 100 liters of water) was sprayed after emergence. NP fertilizers was applied as an inorganic fertilizers source under following rates; 120:80, 150:100 and 180:120 kg ha-1 at sowing, whole P was applied at once, but nitrogen was applied in split doses. Organic and inorganic fertilizers and control were kept in main plot. While maize varieties (i.e. Jalal, Pahari and Azam) were sown in sub plots. Delayed tasseling (62.2), silking (71.1) maturity (98.6), taller plants (175 cm), plants population at harvest (61481 ha -1 ) and biological yield (11111 kg ha -1 ) were recorded when NP was applied at the rate of 180:120 kg ha -1 , whereas highest harvest index (37.1%) and maximum plants population at harvest (65556) were recorded when NP at 150:100 kg ha -1 was used. Jalal variety emerged as best variety with delayed tasseling (61.20), silking (68.6) and produce taller plants (171 cm) with maximum biological yield (10234 kg ha -1 ). In conclusion inorganic source of fertilizers (NP) proved better than organic and Jalal variety is strongly recommended because of better performance in the agro-climatic condition of Peshawar.

Forage maize nutritional quality according to organic and inorganic

“…On the present research, organic fertilization applied to 2A120 hybrid maize significantly surpassed inorganic fertilization with CP values of 10.41%. Moreover, CP contents found in the present research were contrary to those established by Faisal et al (2013) who determined that inorganic fertilization significantly surpassed organic fertilization in accordance to those characteristics. Crude protein fluctuated between values of 10.74 and 10.80% vs 9.86 and 10.05%, for inorganic and organic fertilization, respectively.…”

Incidence and severity of maize streak disease: The influence of tillage, fertilizer application and maize variety

“…In this study the yield response of Obatanpa was greater than that of Domabin, possibly due to the genotypic superiority of the former in terms of nutrient use efficiency and hence grain yield. This agrees with widely accepted assertion that plant genotypes differ in their responses to changing soil fertility and environmental conditions (Faisal et al, 2013).…”

Forage Yield and Quality Indices of Silage-Corn Following Organic and Inorganic Phosphorus Amendments in Podzol Soil under Boreal Climate

“…Earlier researchers reported variations in P use efficiency in different crop species and genotypes, most probably due to their genetic makeup [28,29]. Similarly, different silage-corn hybrids expressed significant variations in forage proteins, minerals, ADF, NDF, TDN, forage energies and milk production [30][31][32]. P amendments with different application rates exhibited significant production potential and nutritional quality of forage species [33][34][35].…”
