Effect of Seed Treatments and Different Levels of Nitrogen on Plant Growth and Seed Yield of Pea (Pisum sativum)

A field experiment was carried out at the vegetable farm in the University of Agriculture, Faisalabad, in 2013-2014 to identify the role of different seed treatments (Rhizobium and Germinator) and nitrogen fertilizer level (0, 22.5, and 45 kg/ha) on growth and yield parameters of two pea cultivars (Meteor and Alena). The outcomes indicated that seed treatments and an optimal amount of nitrogen drastically enhanced emergence percentage, plant height, nodulation, and yield features. Rhizobium and Germinator combined to create the best effect in Growth and productivity, proposing a method for sustainable gain in pea yield under low-input conditions. The experiment was replicated three times in a factorial design where the effect was randomized under a randomized complete block design (RCBD). Interactions and treatments showed considerable variations in most of the parameters. Np + Germinator + 45 kg N/ha treatment recorded maximum emergence (69.4%), plant height (75.4 cm), chlorophyll content (16.32 g/mg), biomass (41.5 g) and harvest index (61%), especially in cultivar Meteor. The Rhizobium and Germinator treatment fared not very well on its own. There was a significant synergistic effect between the combined use of bio-fertilizers with nitrogen, giving a significant mean effect on vegetative Growth, yield components, and physiological characteristics of the plants. This practice has the potential to enhance the production of peas in sustainable agricultural systems. The trial compared pea seed inoculation with Rhizobium and Germinator and nitrogen on Growth and yield in the two cultivars. Aggregate treatments particularly enhanced emergence, biomass and seed yield in the field.
