Abstract

The investigation were carried out with an objective to assess the “effect of plant geometry and nutrition on the phenological traits and chemical composition of pod in okra (Abelmoschus esculentus ‘L’ Moench) cv. Pusa Sawani” at the Department of Horticulture, C.S. Azad University of Agriculture and Technology, Kanpur during rainy season of two consecutive years 2003 and 2004. The experiment comprised four levels of nitrogen (0, 60, 90 and 120 kg ha-1), three levels of phosphorus (0,60 and 90 kg ha-1) and two plant spacing (30x40 and 40x40 cm) in Factorial experiment of Randomized Block Design with three replications. Application of 120 kg nitrogen ha-1 (N3) caused maximum days for first flower initiation (45.98 and 46.93 days), nitrogen content in pod (2.67 and 2.71 %), phosphorus content in pod (0.77 and 0.79 %) and protein content in pod (16.15 and 16.25 %) but maximum days for first fruit formation was observed with N0 treatment (48.13 and 49.08 days) during two years of respectively. 60 kg phosphorus ha-1 (P1) showed maximum days for first flower initiation (46.25 and 47.22 days). 90 kg phosphorus ha-1 (P2) caused to produce maximum nitrogen content in pod (2.36 and 2.38 %), phosphorus content in pod (0.84 and 0.86 %) and protein content of pod (15.06 and 15.14 %), but in this regard P0 treatment took maximum days for first fruit formation (47.18 and 47.25 days) during both corresponding years. Wider spacing (40x40 cm) presented maximum days for first flower initiation (46.78 and 47.73 days), nitrogen content in pod (2.46 and 2.49 %), phosphorus content in pod (0.78 and 0.81 %) and protein content of pod (15.63 and 15.71 %), whereas, maximum days taken for first fruit formation (47.10 and 48.01 days) with closer spacing (40x30 cm) during both the years of experimentation.
