Evaluation of Yield Traits in Garlic under Various Nutrient Management Interventions

摘要

Lack of high yielding varieties and unbalanced fertilisation are generally implicated in the lower productivity of garlic (Allium sativum L.) crop in India. A field experiment was conducted on garlic-maize cropping system at the Punjab Agricultural University Soil Science Research Farm, Ludhiana. Three farmyard manure (FYM) rates (0, 25 and 50 t ha~(-1)), three nitrogen (N) rates (90,120, and 150 kg N ha~(-1)), three P rates (45, 60 and 75 kg P2O5 ha~(-1)) and three K rates (20, 30, and 40 kg K2O ha~(-1)) were randomized in a Latin Square design. After the imposition of FYM and other treatments, garlic (var. PG-17) was raised and yield and kindred variables were recorded at appropriate stages. Results indicate that the economic yield was primarily determined by bulb size and weight. The N, K, and P fertilisers impacted yields significantly in that order. Bolting exhibited negative bearing on yield; it was effectively controlled by higher FYM rates. The P fertiliser effects ceased beyond 45 kg ha1 level and the K effects were not appreciable beyond 20 kg ha~(-1) level. The results of the study can have major implications in influencing the breeding and nutrient management programmes.
