Influence of Plant Geometry and Nutrition on Yield Attributes and Yield of Okra

The investigations were carried out with an objective to assess the “Influence of plant geometry and nutrition on yield attributes and yield of 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. The experiment comprised four level of nitrogen (0, 60, 90 and 120 kg ha?1, three levels of phosphorus (0, 60, 90 kg ha?1) and two plant spacing (30 ??40 and 40 ??40 cm) in Factorial experiment of Randomized Block Design with three replications. Application of 120 kg nitrogen ha?1 (N3) caused maximum diameter of pod (2.27 and 2.25 cm), number of pods/plant (12.58 and 12.93), fresh weight of pods/plant (209.65 and 213.08 g), fresh weight per pod (29.37 and 29.86 g), dry weight per pod (8.01 and 8.31g), pod yield per plot (6.34 and 6.46 kg) and pod yield q ha?1 (132.18 and 134.66 q) but maximum length of pod was recorded with 90 kg nitrogen ha?1 (16.80 and 17.07 cm) during both the years of trials. 90 kg phosphorus ha?1 (P2 ) influenced maximum length of pod (17.46 and 17.61 cm), diameter of pod (2.98 and 3.06 cm), number of pods per plant (11.41 and 11.72), fresh weight of pods per plant (190.16 and 192.95 g), fresh weight per pod (26.43 and 26.81 g), dry weight per pod (7.19 and 7.45 g), pod yield per plot (7.66 and 7.78 kg) and pod yield per hectare (159.67 and 162.11 q) during both the years of experimentations. Narrow plant spacing i.e., 30 ??40 cm hastened maximum pod yield per plot (6.29 and 6.40 kg) and pod yield ha?1 (131.16 and 133.52 q), whereas, wider spacing i.e., 40 ??40 cm showed maximum length of pod (15.90 and 16.08 cm), diameter of pod (2.48 and 2.57 cm), number of pods per plant (13.14 and 13.48), fresh weight of pods per plant (218.15 and 220.94 q), fresh weight per pod (25.15 and 25.55 g) and dry weight per pod (6.85 and 7.10 g) during both the years.
