Effect of organic sources of nutrients on yield, quality and economics of okra [Abelmoschus esculentus (L.) Moench] cv. GAO 5

Abstract

The results revealed that significantly the maximum number of pods per plant (12.47), maximum yield per plant (181.99 g), per plot (4.37 kg), per hectare (101.08 q), maximum number of picking (17.23), length of pod (14.38 cm), thickness of pod (14.91 mm) and crude protein content of pod (15.06%) were found significant with treatment of Vermicompost @ 5 t/ha + Azospirillum @ 2.5 l/ha + PSB @ 2.5 l/ha + KSB @ 2.5 l/ha (T17). The nitrogen uptake (74.36 kg/ha), phosphorous uptake (11.72 kg/ha) and potassium uptake (53.97 kg/ha) was recorded significantly maximum with treatment of Vermicompost @ 5 t/ha + Azospirillum @ 2.5 l/ha + PSB @ 2.5 l/ha + KSB @ 2.5 l/ha (T17). The available Nitrogen (222.08 kg/ha), Phosphorous (48.51 kg/ha) and Potassium (100.60 kg/ha) was recorded significantly maximum with treatment of FYM @ 20 t/ha + Azospirillum @ 2.5 l/ha + PSB @ 2.5 l/ha + KSB @ 2.5 l/ha (T16). On the basis of results obtained from present investigation, it could be concluded that okra cv. GAO 5 should be fertilized with recommended dose of fertilizer (100:50:50 kg NPK/ha) to obtain higher yield with better quality and economic return. Further, for organic production of okra, application of Vermicompost @ 5 t/ha as a organic manure along with biofertilizers Azospirillum @ 2.5 l/ha + PSB @ 2.5 l/ha + KSB @ 2.5 l/ha gave maximum yield with better quality and higher net return.
