“…There was an increase of 24.4% (with 2% WSF) and 23.16% (with 1.5% WSF) in grain yield over control (Mudalagiriyappa et al, 2016). Application of 125% RDF along with 2% DAP spray at flowering and pod formation stages recorded significantly higher growth attributes resulted in increased pod yield of cowpea as compared to 100% RDF (Kavitha et al, 2019). Therefore, foliar nutrition is being recognized as an important method of fertilization in modern agriculture.…”

Background: Foliar application or foliar nutrition is a technique of feeding plants by applying liquid fertilizer directly to their leaves. Water soluble fertilizers have been introduced exclusively for foliar feeding and fertilization. There is very little information about the foliar application of water soluble fertilizers. There is need for more research in this field. Therefore, foliar nutrition is being recognized as an important method of fertilization in modern agriculture. The current study aimed to study the effect of foliar application of water soluble fertilizers on growth and yield of chickpea (Cicer arietinum L.). Methods: The field experiment was conducted during rabi 2017-18, 11 different treatments were laid out in a randomized block design on clay loam soil. In the field, the data was collected and analyzed and the final result was concluded. Result: The experiment revealed that the growth attributes such as plant height (60.28 cm), number of primary branches (5.22), number of secondary branches (22.93) and dry matter accumulation (241.61 g) were maximum with 75% RDF + foliar application of 2% DAP + 2% Urea + 2% WSF at 60 and 80 DAS (T10) and minimum in control (T1) at harvest stage. Further, seed yield (24.26 q ha-1), stover yield (31.38 q ha-1) and biological yield (55.65 q ha-1) was maximum with 75% RDF + foliar application of 2% DAP + 2% Urea + 2% WSF at 60 and 80 DAS (T10) and minimum in control (T1).

“…The higher haulm yield may be due to the beneficial effect of nitrogen on morpho-physiological characters, which influenced growth attributes such as plant height and number of branches/plant. Das and Jana (2015) [5] in pulses and Kavitha et al (2019) [9] in cowpea also found that significantly higher yield attribute like pod length, pods/plant and seeds/pod. The results are in line with findings of Choudhary and Yadav (2011) [3] , Singhal et al (2015) [18] and Dey et al (2017) [6] in cowpea.…”

An agronomic study on cowpea yield, quality and nutrient composition impacted by foliar supplements was carried out in a field experiment at the College Farm, NM College of Agriculture, Navsari Agricultural University, Navsari, during the 2021 kharif season. The experimental plot's soil had a clayey texture and an alkaline reaction. Eight treatment were tested in this experiment using a Randomized Block Design with three replications. The results revealed that the T3 -foliar spray of 2% urea at 35 and 50 DAS significantly influenced all the cowpea yield and yield parameters, including pod length, number of pods/plant, number of seeds/pod, and seed and haulm yield. It was statistically at par with T4 (foliar spray of Pulse Wonder fertilizer at 5 kg/ha) and T2 (foliar spray of 1% Novel). Protein content was significantly influenced by foliar spray of 2% of Urea at 35 and 50 DAS and it was found statistically at par with T4 and T2. Significant increased N content in seed and haulm were shown under foliar spray of 2% Urea. While Fe and Zn content found significantly highest under T5 (Foliar spray of chealated micronutrient Fe and Zn at 0.5% at 35 and 50 DAS). T3 recorded the highest net return of 46659 ₹/ha and greatest B: C ratio (2.97), which was followed by treatments T4 (2.71) and T2 (2.64). Based on the results of a year-long experiment, it can be concluded that full doses of RDF (20:40:00 NPK kg/ha) should be used to grow kharif cowpea, along with foliar sprays of 2% urea or 5% Pulse Wonder fertilizer or 1% Novel (Nauroji organic product) at 35 and 50 DAS to increase yield and financial returns.

“…The highest number of fruits per vine and fruit weight were recorded in foliar application of DAP (1.5%) and boric acid (0.1%) at 35 DAS followed by one more spray of boric Foliar Nutrition with Water Soluble Macro and Micro Nutrient Fertilizers for Yield Maximization in Bush Vegetable Cowpea acid (0.1%) at 45 DAS in cucumber (Mondal et al, 2017). An enhancement in number of flowers per plant, number of pods per plant, pod length and pod weight were noticed in cowpea due to application of 125 per cent RDF along with 2 per cent DAP spray at flowering and pod formation stages (Kavitha et al, 2019). Foliar nutrition of Zn (100 mg L -1 ) and B (100 mg L -1 ) recorded significantly higher fruit length and number of fruits per plant in tomato receiving (Saravaiya et al, 2014).…”

Background: Cowpea is a leguminous crop of indeterminate growth habit and continues to produce flowers throughout its life cycle. In order to realize the genetic yield potential of cowpea, nutrient requirements of later formed flushes also needs to be met. Hence the present study was formulated to assess the effect of foliar application of water-soluble macro nutrient fertilizers viz., NPK 19:19:19 and potassium nitrate and micronutrient fertilizers viz. zinc sulphate and solubor for yield maximization in bush vegetable cowpea. Methods: The field experiment was conducted at Coconut Research Station, Balaramapuram, during Rabi 2020-21. The experiment was laid out in randomized block design with 13 treatments in three replications. The treatments comprised of recommended dose of conventional fertilizers (RDF) NPK 20:30:10 kg ha-1 as control and RDF + foliar application of water-soluble fertilizers 19:19:19 (0.5%) and potassium nitrate (0.5%) with zinc sulphate (0.05%) and solubor (0.025%) in twelve different combinations. Result: Results revealed that compared to RDF alone, RDF + foliar application of water-soluble macro and micro nutrient fertilizers at 45 DAS significantly improved the dry matter production, number of pods per plant and pod weight and recorded a yield enhancement of 22 to 55 per cent. Among the treatments, RDF + foliar application of 19:19:19 (0.5%) and solubor (0.025%) at 45 DAS recorded the highest dry matter production per plant (39.51 g), pods per plant (30.88 no.), pod yield (7410 kg ha-1), net return (82651 Rs ha-1) and B:C ratio (2.26). The treatments, RDF + foliar application of 19:19:19 (0.5%) at 45 DAS; RDF + foliar application of 19:19:19 (0.5%), zinc sulphate (0.05%) and solubor (0.025%) at 45 DAS; and RDF + foliar application of potassium nitrate (0.5%) and solubor (0.025%) at 45 DAS also recorded comparable number of pods per plant, green pod yield, net return and B:C ratio. Considering the highest green pod yield, net return and B:C ratio, RDF + foliar application of NPK 19:19:19 (0.5%) and solubor (0.025%) at 45 DAS could be recommended for yield maximization in bush type vegetable cowpea.
