Impact of nitrogen and spacing on the growth and yield of okra [Abelmoschus esculentus (L.) Moench]

Abstract

The present investigations entitled "Impact of nitrogen and spacing on the growth and yield of okra" was carried out during spring summer season 2015. The applications of nitrogen at 100 kg/ha recorded higher yield attributes of the number of nods per plant, leaves per plant, internodes length, plant height, pod length, number of pods per plant, fruit yield per plant and total green pod yield per hectare. Nitrogen application upto125 kg/ha significantly decrease the days to 50% flowering. The pod weight, pod length, number of nodes per plant, number of pods per plant, fruit yield per plant and total green pod yield per hectare increased higher with the optimum plant to plant spacing of 15 cm. The data revealed the interaction between nitrogen level and plant density was present in case of plant growth and yield contributing characters of okra. Although the highest level interaction of 100 kg N/ha with plant to plat spacing 15 cm produced the high number of nods per plant, pod weight, pod length, number of pods per plant, pod yield per plant and total green pod yield per hectare and the days to 50% flowering decreased was recorded with 125 kg N/ha and plant to plant spacing 20 cm. The highest gross return (Rs.94080) and net return (Rs.84621.3) were obtained from N125S20.
