“…It was reported that GA3 was considered as enhancing the cell division and elongation 2: Nutritional elements (mineral contents) of okra pods as affected by IAA, NAA and GA3 at 100 (mg/l) applied by presowing treatment. (Harrington et al, 1957). Veer Kumar (2002) and Sreedhar (2003) stated that increased stem elongation might be due to the stimulating action of GA3, which alleviated the cell wall by increasing its plasticity.…”

The study was conducted to investigate the effect of different concentration of indole acetic acid (IAA), naphthalene acetic acid (NAA) and gibberellic acid (GA3) on okra pod setting and size, soluble solids content (SSC), vitamin C and mineral contents using flower ovary injection method. The fruit set significantly increased in IAA and GA3 compared to the NAA at 100mg/L concentration. NAA had lower fruit setting than the IAA and GA3 treated plant. The higher pod (fruit) size was obtained in GA3 (18.8 cm²) as compared to the IAA (8.98) and NAA (8.72 cm²) at 100 (mg/L) of concentration. Moreover, the highest SSC was obtained by 100 mg/L of IAA concentration as compared to the GA3 and NAA. The maximum vitamin C was found in IAA and GA3 as compared to 100 mg/L NAA concentration. On the other hand, the higher mineral contents like K, Ca, Mg, Na and Fe was found in 100 mg/L IAA and GA3 concentrations than 100 mg/L NAA concentration. The higher concentrations (100 and 200 mg/L) of IAA and NAA greatly decreased the healthy seed percentage as compared to the lower concentration. However, GA3 increased the healthy seed percentage at 50 and 100 mg/L then decreased at 200 mg/L concentration. Aborted seed percent was increased from 25-100mg/L IAA and NAA and then decreased at 200 mg/L. however it was found increasing trend from 25-200mg/L GA3 concentration. It seemed that GA3 and IAA were better growth regulator as compared to the NAA for okra pod production and development of nutrient content.

“…The use of plant growth regulators activate growth along the longitudinal axis, increase number of leaves, leaf area which subsequently contributes towards higher plant production and productivity. "Gibberelic acid (GA3) is the most widely used plant growth regulator which increases stem elongation along with plant height, growth, dry matter accumulation as well as yield in various crops" (Harrington et al, 1996, Akter et al, 2009) [6,7].…”

A field experiment was conducted during Kharif season 2022 on Cowpea crop at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P) to study the “Influence of Phosphorus and Gibberelic acid on growth and yield of Cowpea (Vigna unguiculata L.)”. The treatments consisted of three levels soil application of Phosphorus (20, 40, 60) kg/ha and foliar application of Gibberelic acid (50, 100, 150) ppm along with control. The experiment was laid out in Randomized Block Design with ten treatments each replicated thrice. Application of Phosphorus 60 kg/ha and Gibberelic acid 150 ppm (treatment 9) in cowpea recorded significantly highest plant height (82.77 cm), more number of nodules/plant (5.57 g), higher plant dry weight (24.90 g), maximum number of pods/plant (15.74), seeds/pod (13.98), highest test weight (20.93 g), higher seed yield (2.37 t/ha), higher stover yield (2.78 t/ha), higher harvest index (30.39%), maximum gross return (INR 63,000.00/ha), net return (INR 40,133.00/ha) and benefit cost ratio (1.76) was obtained in the same treatment 9.
