| dc.description.abstract | An attempt was undertaken to evaluate the effect of different doses of
nitrogen and phosphorous doses on morphological characteristics and
yield attributes of okra at the research field laboratory of Department of
Crop Physiology and Ecology, Hajee Mohammad Danesh Science and
Technology University, Dinajpur during the period from April to July
2015. The experiment was designed with factorial combinations of four
doses on nitrogen (0, 80, 100, 120 kg N/ha) and four doses on
phosphorous (0, 30, 40, 60 kg P/ha), laid out in randomized complete
block design with three replications. Results revealed that plant height,
plant diameter, leaf length, number of leaves, number of brunches, pod
length, number of pods, and yield of okra significantly affected by the
main effect of nitrogen and phosphorous fertilizer. Combined effect of
two fertilizers was also remained significant on various growth and yield
contributing characteristics of okra. The highest plant height (100.65
cm), maximum number of leaves (62.68) and maximum number of
brunches (6.51) were found from N3P2 (120 kg N/ha and 45 kg P/ha)
treatment. Similarly, maximum number of pods per plant (38.19) with
the highest pod length (13.33 cm) of okra was produced from N3P2
treatment. Furthermore, application of 120 kg N/ha and 45 kg P/ha
produced maximum yield of okra (6.66 kg/plot and 9.55 t/ha). Finally,
120 kg N/ha and 45 kg P/ha could be suggested as optimum fertilizer
dose for the maximum growth and yield of okra. | en_US |
