“…The higher dose of N might have enhanced cell division and formation of more tissues resulting in luxuriant vegetative growth giving rise to to the observed tall plants recorded in the present study (Firoz, 2009). Minimum plant height (66.2 and 62.6 cm) in zero N plots might be due to the poor nutritional status which resulted in retarded growth resulting in short plants.…”

Study was conducted in 2006 and 2007 cropping seasons at the experimental field of Federal University of Technology, Minna (9o 401N and 6o 301E), in the Southern Guinea Savanna of Nigeria to determine the effects of N fertilizer and the fruit positions on fruit and seed yield of okro. The treatment comprised factorial combination of five nitrogen levels (0, 30, 60, 90 and 120 kg/ha) and five fruit positions on a mother-plant (3, 5, 7, 9 and 10) which were replicated three times and laid in a Randomized Complete Block Design (RCBD). The results indicated that significant taller plants were recorded in the plots that received 120 kg N/ha while shorter plants were recorded in plots that received 0 N/ha in both years of the study. The higher N level of 120 kg/ha and lower fruit position of 3 significantly gave higher number of fruit yield while the yield decreased with decrease in N level and increase in fruit position on the mother-plant. Similarly, heavier fruits were recorded in lower fruit positions and higher N levels. The fruits formed at the lower position 3 and 5 produced more seeds with higher seed weight than those formed at the higher positions. The results also showed that significantly higher seed yield was recorded at N level of 120 kg/ha ?.

“…As for the comparison test between the means, it was observed that different types of water used in the irrigation of the plants (WW and IW) had a significant influence on all studied variables. However, differing results were reported by Firoz (2009), andZubairu et al (2017), who evaluated the effect of nitrogen fertilization on okra cultivation and found a linear increase in PH up to the maximum limit of 120 kg ha -1 of N.

Water is an indispensable resource for the maintenance of life; however, the available volume for consumption has decreased over a period of life, as a result of which, the availability of water that is inferior in quality has increased. In this context, we aimed to evaluate the growth and yield of okra (Santa Cruz cultivar) under different nitrogen rates and irrigation facilities using post-treated domestic wastewater through sand filter with intermittent flow in a Brazilian semiarid region. The experiment was performed in the Pombal region of the Paraíba state, Brazil using a randomized block design with six nitrogen Rates (N 1 = 0, N 2 = 40, N 3 = 80, N 4 = 120, N 5 = 160, and N 6 = 200 kg ha -1 ) and irrigation by using wastewater. The water was added to the treatment with 100% (160 kg ha -1 ) using nitrogen fertilization recommendation and irrigation water supply. The effects of treatments on the growth and production variables of okra plants were evaluated.

When the soil moisture tension reached to 70 kPa, irrigation water was added to T 3 treatment through surface technique [26] and for each irrigation exercise; 75 mm (11.85 liters) of water was applied. Any surplus water (drainage effluent) was collected in Jarry cans through the drainage outlets provided at the bottom of each Lysimeter chamber.…”

An experimental study was carried out on a Lysimeter with the aim of partially meeting WRs (Water Requirements) of the Okra crop through SWT (Shallow Water Table) while maintaining the SWT at various levels below the ground surface. Under the study, CWR (Crop Water Requirement), yield, water productivity, salt accrual and contribution of SWTs towards meeting the CWR are assessed. The study was designed in accordance with the principles of CRD (Complete Randomized Design) with three treatments and four replications. The treatments; viz. T 1 , T 2 , and T 3 consisted of maintaining the WTDs (Water Table Depths) at 45, 60 and 75 cm, respectively, below the ground surface. The crop was irrigated with a good quality water having EC w = 0.50 dS m -1 and pH = 7.3. The results of the study showed that the crop consumed the maximum amount of water under T 1 treatment, followed by T 2 and then by T 3 treatment. Accordingly, the contribution of SWTs towards the CWR is 94.8, 93.2 and 42.9% of the total CWR under the T 1 , T 2 , and T 3 treatments, respectively. Maximum yield is attained under T 3 treatment, followed by T 2 treatment and then by T 1 treatment. Likewise, maximum water productivity is achieved under T 3 treatment, followed by T 2 treatment and then by T 1 treatment. The dry bulk density (ρ ρ ρ ρ ρ d ) of the soil, under T 1 and T 2 treatments, increased slightly; however, it remained unchanged under the T 3 treatment. The EC se (Electrical Conductivity) of the soil increased, whereas, the pH value of the soil decreased under all the treatments. Statistically, significant difference (p < 0.05) is observed in CWR, yield, water productivity, contribution of SWT towards crop water use, plant height and weight of the Okra pod; whereas, the difference in ρ ρ ρ ρ ρ d , EC se , pH and length of the pod is observed as not significant (p > 0.05) under the three treatments. Accordingly, to make profitable use of SWTs, improve WUE and productivity, and maintain soil fertility, the depth of SWT be controlled at 75 cm for growing of the Okra crop. Adapting to this guideline will help in availing the maximum contribution of SWTs towards meeting the CWR and achieve the larger aim of water conservation.
