Response of sowing time and fertilization on the growth parameters and yield of field pea (Pisum sativum L.) under irrigated conditions of Punjab

Abstract

A field experiment was conducted during Rabi season 2017-18 at the Campus for Research and Advanced Studies Dhablan of G.S.S.D.GS. Khalsa college Patiala with twelve treatment combinations of three sowing time D1 (2 nd fortnight of October), D2 (1 st fortnight of November), D3 (2 nd fortnight of November) in main plots and fertilization levels F1 (25 kg ha -1 P2O5), F2 (45 kg ha -1 P2O5), F3 (25 kg ha -1 P2O5 + Rhizobium inoculation) & F4 (45 kg ha -1 P2O5 + Rhizobium inoculation) in sub plots were tested in split plot design with three replications. Plant growth parameters like emergence count (m -2 ), plant height (cm), number of branches plant -1 , number of leaves plant -1 , dry weight (g) plant -1 and yield were recorded significantly superior with crop sown on D2 (1 st fortnight of November) with F4 (45 kg ha -1 P2O5 + Rhizobium inoculation). D2 (1 st fortnight of November) sown crop with F4 (45 kg ha -1 P2O5 + Rhizobium inoculation) produced significantly higher grain yield (q ha -1 ) and straw yield (q ha -1 ) as compared to others treatments.
