TO DETERMINE THE INFLUENCE OF DIFFERENT NITROGEN DOSES AND SPACING ON THE GROWTH AND DEVELOPMENT OF FIELD PEA (PISUM SATIVUM L.)Drema Nima, Chack Sonbeer and Rina LipiAbstract During the rabi season of 2022-23, a field experiment was carried out at the Himalayan University farm in Arunachal Pradesh. To determine the influence of different nitrogen doses and spacing on the growth and development of field pea (Pisum sativum L.) The experiment were laid out in Randomized Block Design and replicated thrice with 7 treatments T1 N1(30 kg ha-1) +S1(30x 10 cm), T2 N1(30 kgha1)+S2(35x10cm), T3 N1(30 kg ha-1)+S3(40x10cm), T4 N2 (50 kg ha-1)+S1 (30x10 cm),T5 N2(50 kgha-1)+S2 (30x10 cm), T6 N2(50 kg ha-1)+S3 (40x10 cm) and T7 (Control Plot). Observation on plant height (cm), number of leaves plant-1, number of branches plant-1, Dry weight (g plant1), CGR. (g m-2 day-1) and RGR(g g day-1) were recorded. The treatment T2 N1 (30 kg/ha) +S2 (35x10 cm) displayed significant increase in growth and development of pea as compared to the control plot and statistically at par with treatment T1 N1(30 kgha1)+S1(30x10cm). Plant height (43.3), number of leaves plant-1(22.10), number of branches plant-1(2.90), dry weight plant-1(g) (19.20), CGR (0.23) and RGR (0.03) were observed highest in T2. |
