Impact of organic and inorganic sources of nitrogen and phosphorus fertilizers on growth, yield and quality of forage oat (avena sativa l.)

Abstract

ABSTRACT.A field trial was carried out to examine the comparative efficacy of organic and inorganic sources of nitrogen and phosphorous fertilizers alone and in different combinations to find the yield and quality contributing factors of oat (Avena sativa L.) during 2008-09 at Agronomic Research Area, University of Agriculture Faisalabad. The treatments were tested under randomized complete block design using three replications. Significant result were found in respect of plant height (146.3 cm), number of leaves per plant (6.87), number of tillers per plant (8.02), number of tillers m -2 (336), leaf area per plant (128 cm 2 ), fresh weight per tiller (30.10g), dry weight per tiller (5.01g) and green fodder yield (74.67 t ha -1 ) in contrast to organic manures and its combination with inorganic fertilizer (inorganic sources of manures). From the present study it can be concluded to meet the needs of fodder; it is better to use inorganic sources that are more effective and quick in response while organic sources are more environmental friendly than inorganic sources.

Effect of Seed Rate and Nitrogen Level on Growth and Yield of Fodder Sorghum under Custard Apple Based Horti-Pastoral System

“…Increase in number of leaves and LAI more photosynthetic surface and further stimulated the growth. Higher leaves plant -1 and LAI due to nitrogen application have been reported by Ahmad et al, (2011), Osman et al, (2010 and Patil et al, (2014). The interaction between seed rate and nitrogen levels was non-significant.…”

Influencia del biocarbón aplicado al suelo sobre atributos de rendimiento y calidad de avena forrajera

“…Asimismo, Fawad et al (2017) registraron hasta 33% mayor AP cuando aplicaron BC en relación al control; ellos concluyeron que el BC disminuye la pérdida de los fertilizantes aplicados, debido a su capacidad de adsorción. En este mismo sentido Ahmad et al (2011) y Torres-Moya et al (2016 mencionan que con la adición de fertilizantes se mejora el desarrollo del cultivo de avena. Tal práctica pudo favorecer la influencia positiva del BC sobre la AP en el presente estudio.…”

Do fertilizers and cropland influence the agricultural production value in the same way? Evidence using the autoregressive distributed lags approach of cointegration

“…Different input factors have different influences on agricultural production. For instance, while the Integrated Pest Management (IPM) seeks to use pesticides when other options are ineffective (Hassanali et al, 2008;Bale et al, 2008), the Integrated Nutrients Management (INM) seeks to balance both organic and inorganic fertilizers (Goulding et al, 2008;Ahmad et al, 2011). Indeed, the ideal should be the development of organic farming.…”
