Abstract
An experiment was conducted to compare the forage yield and qualify of oat (Avena sativa L.) genotypes (F-413, SGD-46, F-408, F-301, SGD-2011, SGD-3, SGD-37, SGD-40, SGD-5 and S-2000) at Fodder Research Institute, Sargodha, Pakistan during the year 2011 to 2012. Experiment was laid out in randomized complete block design (RCBD) having three replications and a net plot of size 1.6 × 5 m. The varieties were differed significantly (P ≤ 0.05) in yield, growth and quality parameters. The variety SGD-40 produced significantly higher green forage yield (80.00 t·ha-1) and dry matter yield (10.95 t·ha-1) than other varieties due to taller plants (145.73 cm), more number of tillers (7.78 m-2) and leaf area per plant (95.08 cm2). It also had the highest crude protein percentage (13.84%). Correlation analysis of quantitative and qualitative characters indicated the strongly positive association of green forage yield with dry matter, crude protein and ash content. While green forage yield was negatively correlated with the number of tillers per plant, keeping in view both forage yield and crude protein contents the genotype SGD-40 grown under the condition of Sargodha (Pakistan).
Highlights
In agriculture sector livestock is a vital component because 30% - 35% rural population of Pakistan is involved in livestock rearing
Plant Height Plant height is a major factor contributing towards forage yield of different crops
The results showed that maximum leaf area of (95.08 cm2) of genotype SGD-40 it is statically at par with SGD-2011 compared to all other genotypes while minimum leaf area (80.09 cm2) was recorded in genotype
Summary
In agriculture sector livestock is a vital component because 30% - 35% rural population of Pakistan is involved in livestock rearing. To run an efficient livestock industry high yielding and nutritious fodder cultivars are needed. Oat has the advantage of being winter hardy and serves as catch crop [5]. The improved varieties of oat can produce three-fold green fodder, that is, 60 to 80 tones/ha and can feed double number of animals per unit area as against the traditional fodder crops [6]. With the introduction of new high-yielding oat varieties, the farmers in KPK have recognized oat as important winter fodder for filling the fodder gap [7]. Many cultivars of oat have high feed value if cut at flowering stage or soon after it and it can meet the demand of rapidly growing livestock industry of Pakistan. A field experiment with seven oat varieties was under taken to evaluate and identify suitable variety for Sargodha area
