Effect of Foliar Application of Micronutrients on Growth and Yield of Greengram (Vigna radiata L.)

Abstract

Background: Greengram (Vigna radiata L.) is one of the most important pulse crops in India. It is a protein rich staple food which contains about 25 percent protein; It belongs to family leguminaceae so it has the capacity to fix atmospheric nitrogen. Soil application of nutrients is often not enough to meet the growing crop demand particularly in short duration crop like greengram. Therefore, it is hypothesized that foliar nutrition in addition to soil application in commensuration with prevailing weather particularly rainfall will go a long way in meeting crop nutrient need and thereby may help in enhancing poductivity. Foliar application of nutrients using water soluble fertilizer is on the possible ways to enhance the productivity of pulses like greengram. The importance of foliar application of micronutrients i.e., Zinc is essential for enzymes that are involved in many metabolic reactions, necessary for chlorophyll production and for starch formation aids in seed formation. Iron is essential for maintainance of chlorophyll and also an essential component of haemoglobin molecule. Manganese has a role of formation of plants naturally occurring antifungal compounds helping to fight disease infection. It is involved in the enzyme the growth may have biological reactions in plant tissue. Methods: A field experiment was conducted during Zaid season 2019-2020 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, (U.P.) India. To study the “Effect of foliar applied micronutrient on growth and yield of Greengram (Vigna radiata L.)”. The present investigation was laid out in randomized block design (RBD) consisted of 9 treatments replicated thrice.Result: The results revealed that the maximum growth attributes such as plant height (42.42 cm), dry matter accumulation (113.39 g/m2) and crop growth rate (1.69 g/m2/day) was recorded with RDF + Fe 0.5% + Zn 0.5% + Mn 0.5% at 30 DAS, whereas maximum number of nodules/plant (11) was recorded with RDF+ Fe 0.5% at 30 DAS. However, higher yield and yield attributes i.e. Number of pods/plant (58.40), Number of grains/pod (9.73), 1000 grain weight (38.38 g), seed yield (1384.33) kg/ha, stover yield (2253.33) kg/ha and harvest index (42.44 %) was recorded with RDF + Fe 0.5% + Zn 0.5% + Mn 0.5% at 30 DAS. Similarly, higher Net returns (Rs 59912/ha) and benefit cost ratio (1.51) was also recorded with RDF + Fe 0.5% + Zn 0.5% + Mn 0.5% at 30 DAS as compared to control (RDF + water spray).

The Effect of Paddy and Coffee Husk as the Organic Manure on the Vegetative and Yield Parameters of Moth Bean [Vigna aconitifolia (Jacq) Marechal]

“…The influencing factors are always for the growth of the plant height and it is of the nutrients which are from the organic manures and biofertilizers work as the available nutrients for the best growth of the plant height (Darshanth and Singh, 2014). Highest number of leaves (13.66) were found in leafy vegetables with the treatment of dead sheep compost in comparison with control (8.66) (Al-Sabbagh et al,2020).Similar results were observed by Kavya et al, (2021) that on applying RDF + Fe Influence of paddy and coffee husk as the organic manure on the yield parameters of the moth bean [Vigna aconitifolia(Jacq) Marechal] at 90 DAS…”

“Influence of Micro Nutrients and Naphthalene Acetic Acid on Growth, Yield and Economics of Summer Greengram (Vigna radiata L.)”

“…The maximum test weight observed with application of Zn(100ppm) might be due to greater mobilization of photosynthesis to the developing seeds [8]. Further, maximum test weight was observed with application NAA (50 ppm) might be due to greater mobilization of metabolites from leaves to pods.…”

“…By promoting more vigorous regrowth and increasing the yield potential stage period, micronutrient administration before visible symptoms of their deficiency might improve a crop. Micronutrient applications can increase plant resistance to environmental stresses and increase potential yield [8].…”

“…It is a part of the enzyme, and growth of the enzyme may cause biological processes in plant tissue. It is also known to have a role in photosynthesis and act as an enzyme activator for a number of different enzyme-related functions [8].…”

Response of Tomato (lycopersicum Esculentum L.) to Imbibing Seeds by Ga3, And Foliar Spraying by Boron And Α-tocopherol

“…plant -1 ). Increased yield due to boron application and may be attributed to enhanced photosynthesis activity and increased production and accumulation of carbohydrates and favorable impact on vegetative growth, flowers and fruits, which increased number of fruits per plant in addition to increasing the size (Kavya et al 2021). Additionally, α-Tocopherol functions as an antioxidant and protects cellular membranes to ensure that metabolic processes are carried out properly, promotes the representation of carbon, stimulates the accumulation of metabolism and carbohydrates, increases storage in fruits, and works to prevent plant tissues from harmful oxygen derivatives that interfere with the efficiency of numerous enzymes (Shao et al, 2007).…”
