Abstract

An experiment was conducted at Ornamental Horticulture nursery, The University of Agriculture, Peshawar during July 2012 to study “Influence of DAP seed priming and soaking durations on yield and yield associated traits in okra”. The experiment was laid down in Randomized Complete Block Design with split plot arrangement having three replications. Four DAP concentrations i.e. 0.5%, 1%, 1.5%, 2% with a difference of 4 hours soaking durations from 4 hours soaking to 48 hours along with un-primed seed were studied. Data were recorded on production traits viz. plant weight (gm), number of pods plant-1, pod length (cm), number of seeds pod-1 and pod yield (kg ha-1). The results of the study revealed that all the studied traits were significantly affected by concentrations and soaking durations and its interactions. Mean values showed that maximum plant weight (489.12 gm), number of pods plant-1 (35.95), pod length (11.09 cm), number of seeds pod-1 (53.26) pod yield (3845.54 kgha-1) at 0.5 % DAP solution. Mean values of interactions result showed that maximum number of pods plant-1 (47.16) and pod yield (5255.27 kg ha-1) was recorded by the seed soaked for 32hr in 0.5% DAP solution. Maximum number of pod length (12.63 cm) was recorded by the seed soaked for 24hr in 1% DAP solution, whereas, maximum number of seeds pod-1 (66.13) was recorded by the seed soaked for 32hr in 1% DAP solution. DAP solution @ 0.5% performed best in most of the parameters while distilled water showed poor performance. DAP concentrations @ 0.5 % for 32h is recommended for seed priming for obtaining maximum yield in Okra.
