Yield and Quality of Forage Oat (<i>Avena sativa</i> L.) Cultivars as Affected by Seed Inoculation with Nitrogenous Strains

Abstract

Nitrogen availability can be enhanced with the application of nitrogen fixing bacteria and it may be helpful in increasing forage yield and improving quality of oat. Therefore, a field trial to evaluate the effect of seed inoculation with nitrogen fixing bacteria on forage yield and quality of oat was carried out at Agronomic Research Area, University of Agriculture, Faisalabad during Rabi season 2013-14. The experiment was laid out in Randomized Complete Block Design (RCBD) with factorial arrangements using three replications. The experiment was comprised of two integrated approaches. The first approach was oat cultivars consisting of four treatments, V1 (AVON), V2 (S-2000), V3 (S-2011) and V4 (PD2LV65) and the second approach was seed inoculation consisting of three treatments, S0 (control), S1 (Azotobacter spp.), S2 (Azospirillum spp.). Fisher's analysis of variance technique was used for statistically interpretation of data by using least significant difference (LSD) test at 5% level of probability. Nitrogen fixing bacteria significantly affect the germination count (m −2 ), plant height (cm), number of tillers (m −2 ), number of leaves per tiller, leaf area per tiller (cm 2 ), green forage yield (t•ha −1 ) and dry matter yield (t ha −1 ). The maximum green forage yield (85.2 t•ha −1 ), dry matter yield (14.1 t•ha −1 ) and crude protein (11.5%) were recorded where Azotobacter inoculation was applied. The interaction between cultivars and nitrogenous strains was significant for green forage yield (t•ha −1 ), dry matter yield (t•ha −1 ) and crude protein (%). Conclusion showed that cultivar Sargodha-2011 which was inoculated with Azotobacter spp. gave higher forage yield of good quality.

Effect of Mineral -Biofertilizer on Physiological Parameters and Yield of Three Varieties of Oat (Avena sativa L.)

“…( 7) indicates the superiority of Shaffa with B1 which gave the highest plant height 83.66 cm in the first season with an increase reached to 23% compared to Shaffa, that gave the lowest plant high 67.47 cm, in the second season, Genzania produced the higher plant high with B1treatment (96.28 cm) with an increase reached to 24.47% as compared to Genzania with B0 (75.86 cm). This is consistent with (Saleem et al, 2015).…”

“…In the second season B4 with Genzania gave 842.50 tiller. m -2 with an increase of 85.37 and 59.01%, as compared with Genzania in control treatment which gave lowest number was 332.90, 492.59, tiller.m -2 in two seasons, this is consistent with Saleem et al (2015).…”

Fodder quality and nitrate estimation of oats grown under different nutrient management options

“…Addition of organic nutrient sources to soil (FYM and PGPR) along with reduced dose of chemical fertilizers could have provided essential nutrients to crop throughout growing period, hence crops remained free from nutrient stress and also sufficient nutrient supply accelerated the protein synthesis from carbohydrates and reduced the rate of lignification, thereby maintaining the fodder quality. Saleem et al (2015) also reported the significant improvement in DM, CP, fat and TA content of fodder oats due to seed inoculation with biofertilizer. In addition to this, the foliar application of panchagavya enhanced the quality characters of fodder oats because it contains considerable amounts of N and other essential plant nutrients which could have helped in succulent growth, thus lower fibre fractions.…”

“…Significantly higher DFY with 75% RDF + PGPR + Panchagavya might be associated with increased green fodder yield (GFY) and DM content, thus DFY. PGPR activates certain growth promoting enzymes which might have played vital role in boosting green fodder yield (Saleem et al 2015). Further, the higher NPK fertilization either from chemical fertilizers or panchagavya enhanced the chlorophyll content which leads to increased photosynthates, protoplasmic constituents and accelerated cell division and elongation which ultimately resulted into luxuriant vegetative growth as well as GFY.…”

Research Article Genetic parameters and multi-trait selection of white oats for forage

“…The increment of leaf content in relation to stalk content is of great interest for forage breeders because of the higher nutritional quality and digestibility of foliar tissues (Tremblay et al, 2001). Also, the increase in leaf area results in larger photosynthetically active area, which elevates the plant's capacity to produce photoassimilates and consequently, dry matter of high quality per unit of area (Saleem et al, 2015). The highest gains with selection for leaf area (Table 2) were evidenced through the genotypes BRISASUL (14.30%), CGF07-027-1 (13.76%) and CGF0705-7 (11.20%).…”
