Cowpea (Vigna unguiculata) is popularly known as lobia in India, now cultivated throughout the tropics and sub-tropics and used as pulse, green vegetable, fodder, green manure and its productivity is 683 kg ha -1.Vermiwash is a liquid leachate that is collected after the passage of water through the column of worm action. It is a collection of excretory products and mucous secretion of earthworms along with micronutrients from the soil organic molecules. This bio-liquid is rich in nutrients, microorganisms, enzymes, vitamins and plant growth hormones which increase the resistant power of crops against various diseases and enhances the productivity of crops.. The nutrients present in vermiwash are in water-soluble form and meet the immediate requirements of crop plants. Further, it contains nitrogen fixing and nutrient solubilizing bacteria. Generally, foliar spray of vermiwash of vermicomposting supplies nutrients to higher plants more rapidly than soil and root application methods. Vermiwash spray persists on leaf surface and resulted in leaf thickness, increase in photosynthetic activity, internode growth, improved plant physiology and finally increased the yield (Selladuraiet al., 2009). Humic acid is a commercial product containing many elements which improve the growth and yield of cowpea. The fermented organic liquid fertilizer panchagavya contains nutrients, plant growth regulators and microorganisms which help in plant growth, yield, metabolic activities and gives resistant to pest and diseases. The commercial seaweed extract contains major and minor nutrients, amino acids, vitamins and other growth promoting substances. DAP is a complex fertilizer containing 18 % nitrogen and 46 % phosphorus. The Naphthalene acidic acid is a auxin and very effective in promoting growth and yield of pulses. It may be concluded from the results that the foliar application of 2 % DAP along with 40 ppm NAA is recommended to cowpea to enhance the yield and to obtain higher returns.

Pigeonpea is an important pulse crop and one of the major sources of protein in India. In the present study, investigations were undertaken to study the role of foliar spray of different plant growth regulators (PGRs) in altering morphology and enhancing the yield potential of pigeonpea varieties VBN 1, APK 1 and VRG 62. Among different plant growth regulators (PGRs) studied, foliar application of Giberellic acid (GA3) significantly increased plant height, number of leaves and branches in pigeonpea. This was followed by Brassinosteroid (BR). Foliar application of PGRs significantly increased both the growth attributes and yield. Various yield components viz., days to 50 per cent flowering, days to maturity, number of flowers per plant, number of pods per plant, number of clusters per plant, number of seeds per pod, hundred seed weight and harvest index were enhanced by PGR application. Maximum dry matter accumulation and fertility co-efficient was recorded in the treatment (T9), i.e., BR application @ 0.1 ppm than the other treatments. It is concluded that foliar application of BR @ 0.1ppm is advantageous in enhancing both growth and yield of Pigeonpea and thus BR foliar spray can be recommended for adoption by the farmers, to maximize the yield in Pigeonpea.

The field experiment was undertaken at the District Seed Farm, Kalyani at Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal during summer season of 2012 and 2013 to study the growth and yield of summer groundnut as influenced by application of water soluble foliar grade fertilizer. Application of liquid grade fertilizerat early growth stage up to 45 DAE did not influence the plant height and dry matter production significantly, but towards maturity varied significantly (P ≤ 0.05). Crop growth rate was faster at early part of the crop age and gradually slows at later part towards maturity. Foliar application of water soluble fertilizer along with RDF 85% had the significant (P ≤ 0.05) influence to increase the number of pods per plant, but shelling percentage and hundred kernel weight did not vary significantly. Liquid grade fertilizer either starter dose or booster dose or in both had the positive response to increased the groundnut pod yield up to 4-6 % over RDF only. The crop was equally responsive in increasing the pod yield, when RDF was reduced by 15% along with foliar application of liquid grade fertilizer. The foliar application of water soluble fertilizer was not the substitute to soil applied inorganic fertilizer. Instead, foliar supplementation of nutrients showed positive response to increase the pod yield, in addition to the fertilizers added to soil. Gross return decreased with reduction in amount of RDF applied for the crop, but gross return increased, when water soluble foliar grade inorganic fertilizer was supplemented with RDF. The maximum gross return of `150399 was obtained. The results obtained from correlation analysis carried out to examine the linear relationship between pod yields with different plant characters. Data obtained in case of dry matter of the plant was 0.995 and 0.997 in the respective years at 1% level of significance. Thus, it was concluded that dry matter content of plant is solely responsible over the yield increase in groundnut and foliar application of inorganic fertilizers in addition to that in soil has helped in better adsorption of nutrients in adequate amount by the crop.

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2019-2020 and 2020-2021 to investigate the effect of vermiwash on growth, yield and quality of brinjal and to find out suitable foliar dose of vermiwash for optimizing the yield of brinjal. There were five treatments comprising T1= Chemical fertilizer (CF) + foliar spray of distilled water (control), T2 = CF + foliar spray of 10% vermiwash, T3 = CF + foliar spray of 20% vermiwash, T4 = CF + foliar spray of 30% vermiwash and T5= CF + foliar spray of 40% vermiwash. Results revealed that, vermiwash treated brinjal plants showed better growth and yield parameters than the control plants. The highest average brinjal fruit yield (29.99 t ha-1) was found in T3 treatment i.e., foliar spray of 20% concentration of vermiwash and the lowest (26.35 t ha-1) came from control. On the other hand, nutritional quality (moisture content, TSS, β carotene and nutrient content) were seen to be higher in vermiwash treated treatment compared to control treatment. The study suggests that, 20% concentration of vermiwash could be used as effective foliar spray for eco-friendly and higher yield of brinjal.

Tannery wastewater mainly comes from leather industries. It has high organic load, high salinity, and many other pollutants, including chromium (Cr). Tannery wastewater is generally used for crop irrigation in some areas of Pakistan and worldwide, due to the low availability of good quality of irrigation water. As tannery wastewater has many nutrients in it, its lower concentration benefits the plant growth, but at a higher concentration, it damages the plants. Chromium in tannery wastewater accumulates in plants, and causes stress at physiological and biochemical levels. In recent times, the role of micronutrient-amino acid chelated compounds has been found to be helpful in reducing abiotic stress in plants. In our present study, we used lysine chelated zinc (Zn-lys) as foliar application on maize (Zea mays L.), growing in different concentrations of tannery wastewater. Zinc (Zn) is required by plants for growth, and lysine is an essential amino acid. Maize plants were grown in tannery wastewater in four concentrations (0, 25%, 50%, and 100%) and Zn-lys was applied as a foliar spray in three concentrations (0 mM, 12.5 mM, and 25 mM) during plant growth. Plants were cautiously harvested right after 6 weeks of treatment. Foliar spray of Zn-lys on maize increased the biomass and improved the plant growth. Photosynthetic pigments such as total chlorophyll, chlorophyll a, chlorophyll b and contents of carotenoids also increased with Zn-lys application. In contrast to control plants, the hydrogen peroxide (H2O2) contents were increased up to 12%, 50%, and 68% in leaves, as well as 16%, 51% and 89% in roots at 25%, 50%, and 100% tannery water application, respectively, without Zn-lys treatments. Zn-lys significantly reduced the damages caused by oxidative stress in maize plant by decreasing the overproduction of H2O2 and malondialdehyde (MDA) in maize that were produced, due to the application of high amount of tannery wastewater alone. The total free amino acids and soluble protein decreased by 10%, 31% and 64% and 18%, 61% and 122% at 25%, 50% and 100% tannery water treatment. Zn-lys application increased the amino acids production and antioxidant activities in maize plants. Zn contents increased, and Cr contents decreased, in different parts of plants with Zn-lys application. Overall, a high concentration of tannery wastewater adversely affected the plant growth, but the supplementation of Zn-lys assertively affected the plant growth and enhanced the nutritional quality, by enhancing Zn and decreasing Cr levels in plants simultaneously irrigated with tannery wastewater.

Field experiments were conducted at Pulses and Oilseeds Research Station, Berhampore, Murshidabad, West Bengal during <italic>pre kharif, kharif and rabi</italic> seasons of 2011-12, 2012-13 and 2013-14 to study the effect of water soluble fertilizer spray on growth and yield of greengram, blackgram, lathyrus, lentil and chickpea. Pulses are mostly grown by the farmers without any fertilizer application, as positive effect of supplying legume plants with supplementary nitrogen was found to have beneficial effect on enhancing growth and increasing seed yield. Five sets of experiments were laid out in a split plot design with three replications <italic>viz.</italic> two levels of basal fertilizer application (F<sub>0</sub> -No basal dose of fertilizer, F<sub>1</sub> -Basal dose of fertilizer application @ 20, 40, 40 kg N, P<sub>2</sub>O<sub>5</sub>, K<sub>2</sub>O ha<sup>−1</sup>.) as factor A in main plot and seven levels of foliar spray of water soluble fertilizers at pre flowering stage (no spray, 0.5% NPK(19-19-19), 1% NPK(19-19-19), 2% NPK(19-19-19), 3% NPK(19-19-19), 2% DAP, 2% Urea) as factor B in sub plot. Significantly higher seed yield of pulses were recorded with application of 2% urea spray over basal dose of fertilizer application The lowest seed yield was recorded with no basal fertilizer and spray. Without basal dose of fertilizer application, 3% NPK (19-19-19) spray recorded highest seed yield. Under basal dose of fertilizer application, the results showed a gradual increase in yield with the increase in concentration of NPK (19-19-19) fertilizer spray up to 2%, Among the fertilizer spray treatments irrespective of basal dose of fertilizer application, urea spray was significantly better than all other treatments.

A study of effect of foliar application of gibberellic acids (GA) and napthalene acetic acids (NAA) each at 0, 10, 20 and 30 ppm concentrations revealed that plant growth, phonological parameter, yield-attributing parameters and yield of okra increased significantly with the increase in concentration. The application of GA at 30 ppm gave maximum fruit length, fruit thickness, green fruits yield and dry weight of fruits. Similarly, 30 ppm NAA gave maximum fruit length, fruit thickness, green fruits yield and dry weight of fruits. The treatment interactions were found significant only at 45 DAS stage in plant height, at 15 DAS stage in case of leaves/plant and only at 45 and 60 DAS stage in case of branches / plant. The highest net returns was obtained with application of 30 ppm each of GA and NAA .

Foliar Application seems to be an upcoming and ongoing research area especially in the field of agriculture. This is been in practice in various parts of the world and proved its positive results in its field [1,2]. Foliar application can be explained as spraying the suitable fertilizer solution (condition is, that it should be water soluble) on the surface of the leaves of growing plants [3]. This practice not only saves quantity of fertilizer used but also improves the uptake of a particular micronutrient by the crops and boosts the yield too. Interaction between crop’s genetic potential and the environment in which it grows is detrimental for the yield of a crop [4]. Soil application of nitrogen is a conventional method to supply nitrogen to plants and for improvement in any field adhering to the old ways will not be a better option [4]. In some instances, the availability of urea becomes inadequate for the farmers at sowing time. In such situation the foliar application of plant nutrient is effective and economical for some crops [5]. It has been shown in some studies that uptake of micronutrients directly from plants is more rapid and quicker for better results in yields than soil application[1]. As mentioned above, that the fertilizer should be water soluble for foliar spray and moreover, it should also be noted that the particular crop plant also should be suitable for aerial spray. The best results of foliar application also depends on the soil condition as if soil conditions are unfavourable when micronutrients are needed, it may be desirable to make foliar applications of the plant nutrients
