Impact of foliar nitrogenous source on growth and yield of okra

The present investigation entitled “Impact of foliar nitrogenous source on growth and yield of okra, conducted at University Research Farm, GHRU, Saikheda in Rabi Season of 2023, are presented and described in this chapter. The research trial conducted in nine treatments with control, and replicated in three times, the data was anlysed in Randomized Block Design. The research trail was carried on Okra crop cv. Red Okra for observed the growth, yield and economics. The treatment details are T₁- Control, T₂- 0.5% urea (30 DAS) + 1% urea (45 DAS), T₃- 0.75% urea (30 DAS) + 1% urea (45 DAS), T₄- 1% urea (30 DAS) + 1% urea (45 DAS), T₅- 2% urea (30 DAS) + 1% (45 DAS), T₆- 0.5% urea (30 DAS) + 0.5% CaNO₃ (45 DAS), T₇- 0.5% urea (30 DAS) + 1% CaNO3 (45 DAS), T₈- 0.5% urea (30 DAS) + 0.5% KNO₃ (45 DAS) and T₉- 0.5% urea (30 DAS) + 1% KNO3 (45 DAS). In the research trial observation was taken such as plant height (cm) at 45 and 75 DAS, number of leaves per plant 45 and 75 DAS, number of branches per plant at 75 DAS, number of nodes per plant, fruit length (cm), fruit width (cm), yield per plot (kg), yield per ha (q/ha). The results revealed that plant height at 45 and 75 DAS (38.63 and 71.98 cm), number of leaves per plant at 45 and 75 DAS (13.68 and 28.01), number of branches per plant at 75 DAS (12.68), number of nodes per plant (22.12), fruit length (14.09 cm), fruit width (6.24 cm), yield per plot (20.58 kg) and yield per ha (175.26 q/ha), while the minimum value of all the above parameters was observed under the control plot.
