Comparative study on Physicochemical and Microbiological Assessment of Combined Sprouted/Fermented Sorghum (S. bicolor) blended with Cowpea (Vignia unguiculata) and Groundnut (Arachis hypogea)

Cereal grain (Sorghum, millet, and maize) and legumes (beans, soya beans, and groundnut) are the agricultural raw materials used both commercially and traditionally in the production of weaning foods, particularly in developing countries. A variety of cereals (sorghum) are used singly or in combination to produce several fermented and sprouted weaning foods using simple processing methods. The study investigated the effect of sprouting and fermentation on some functional properties and microbiological quality of the food formulations prepared from sorghum (S. bicolor), cowpea (Vigna unguiculata), and groundnut (Arachis hypogea) in a ratio of (70:20:10). Viscosity, functional properties, and microbiological assessment of the food formulations were evaluated using standard laboratory methods of analysis. Sprouting, fermentation singly and in combination significantly (P<0.05) decreased gruel viscosities (197825.1cps – 225.019.4cps) for red sorghum and (1952022.9cps – 230018.6cps) for white sorghum variety. The results of ranged bulk density from (0.700.01g/ml – 0.600.02g/ml) for red sorghum and (0.710.02g/ml – 0.600.02g/ml), while increasing water absorption capacity in sprouted and fermented sorghum samples for (FCR 6.470.00g/ml, FCW 5.430.01) and SCR 6.030.00g/ml, SCW 4.410.02g/ml) compared to raw and the composite blends. Total bacterial counts reduced significantly with sprouting and fermentation. The dominant microorganisms isolated in this study were all fermenters non-pathogenic microorganisms which are safe for consumption Staphylococcus species dominant only in the non-fermented products

APPLICATION OF LIQUID ORGANIC FERTILIZER AND NPK Blue ON THE GROWTH OF PEANUT (Arachis hypogea L.)

Peanuts make a significant contribution in meeting the needs of legumes, especially in Southeast Aceh Regency. This research was conducted in Kisam Village, Bambel District, Southeast Aceh, with an altitude of ± 220 m above sea level. The aim of the study was to determine the application of liquid organic fertilizer and the dose of NPK fertilizer on the growth and development of peanut (arachis Hypogea L.) plants. The design used in this study was a Randomized Block Design (RAK) which was arranged in a factorial manner with 9 treatment combinations with 3 (three) replications. The treatment consisted of 2 (two) factors, namely the first treatment of liquid organic fertilizer (P1) 2cc/l water, (P2) 4 cc/l water and (P3) 8 cc/l water, while the second factor was the dose of NPK fertilizer (N1 ) 1.25 g/plant, (N2) 1.75gr/plant and (N3) 2.25 g/plant. The observed variables were plant height, number of branches, number of petioles and number of leaves. The results showed that the application of liquid organic fertilizer (P1) gave the best results on plant height, number of branches, number of petioles and number of leaves. Dosage of NPK (N3) fertilizer gave the best results on plant height, number of leaves. The interaction of treatment with liquid organic fertilizer (P1) and dose of NPK fertilizer (N3) gave the best effect on the growth and production of peanut plants. The results of the analysis of variance showed that there was no significant interaction between the treatment of giving liquid organic fertilizer (Pocnasa) and chemical fertilizer (NPK Biru) to all observed variables.

During Summer (zaid) of 2021, the current study conducted at CRF (Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, (U.P). The experiment used a RBD (Randomized Block Design) with 3 replications. There are 9 treatments used, each with distinct levels of spacing and Zinc applied. The agricultural field was found to be uniformly sandy loam with neutral pH (7.4). The treatments consisted of Zinc levels at 10 kg/ha, 12.5 kg/ha and 15 kg/ha and spacing at 25 × 10, 30 × 10 and 35 × 10 whose effect is observed in Groundnut (Var – K6). The treatment 6 with (Zn 15 kg/ha + 30×10) recorded significantly maximum in plant height (40.36 cm), number of nodules/plant (49.43), plant dry weight (21.88 g). The treatment 6 with (Zn 15 kg/ha + 30×10) also recorded significantly higher in yield attributes viz., pods/pant (27.72), kernels/pod (1.92) and seed index (100 seed weight) (39.21 g), pod yield (2773.30 kg/ha), seed yield (1494.67 kg/ha), Haulm yield (5907.67 kg/ha), harvest index (20.18%), oil content (48.26%). The treatment 6 with (Zn 15 kg/ha + 30×10) also recorded significantly the maximum cost of cultivation (50,449.50 INR/ha), gross return (119218.55 INR/ha), net return (68769.05 INR/ha) and B: C ratio (1.36).

Green-based processes applied for valorization of peanut by-product: In vitro evaluation of antioxidant and enzymatic inhibition capacities

Peanut (Arachis hypogea L.) industrial processing generates underused by-products, which are mostly discharged. In this work, extracts from peanut by-product were obtained by Supercritical Fluid Extraction (SFE), Pressurized Liquid Extraction (PLE) and Subcritical Water Extraction (SWE), and compared to Soxhlet (SOX). Yield values varied from 12.94% to 37.65% for SOX-water and SWE, respectively. The quality of the extracts was evaluated by total phenolic content (TPC), antioxidant and enzymatic inhibition potentials, and fatty acids profile. Best TPC performance and high antioxidant capacity were obtained from samples using ethanol/water by PLE and Soxhlet. High inhibition of human salivary α-amylase was achieved by PLE and Soxhlet samples recovered with ethanol/water mixture. The inhibition of porcine pancreatic α-amylase was higher from samples by SFE and Soxhlet with ethanol. High-pressure methods are appealing alternatives for the recovery of bioactive extracts from peanut by-products, with functional properties and potential inhibitor of digestive enzymes.

Iron biofortification potential of siderophore producing rhizobacterial strains for improving growth, yield and iron contents of groundnut

Biofortification in crops is an effective and sustainable approach to reduce global malnutrition. Groundnut (Arachis hypogea L.) is inherently low in micronutrients, especially iron. A greenhouse study was conducted to evaluate the effect of siderophore producing bacterial strains (SPBs) on growth, yield and iron content of groundnut. Three efficient SPBs identified as Bacillus subtilis and their consortia were used alone and with soil or foliar applied iron. The results revealed that the inoculation of SPBs alone and combination with soil applied Fe, showed maximum relative increase of 63 and 86 percent in shoot fresh and dry weight respectively. Likewise, the number of pods plant−1, pod weight plant−1, 20 pod length and 100 kernel weight of groundnut were increased significantly in response to sole application SPBs and their combinations with soil applied (SA) or foliar applied (FA) iron. Moreover, nutrient (N, P, K, Zn & Fe) concentrations in kernel and straw were also showed significant differences in all treatments. Findings further revealed that the combined application of SPBs + Fe-SA increased total Fe-uptake of groundnut between 24.14 to 49.75 percent while for SPBs + Fe-FA treatment this increase varied between 14.73 to 45.72 percent (over to the SPBs alone) The overall results indicated that SPBs have the potential to increase growth, yield and nutrient contents of groundnut which advocate that microbial-mediated Fe biofortification of groundnut could be a promising strategy to ameliorate Fe deficiency-induced disordering in human beings especially in developing countries.

Plant Growth-Promoting Activity of Bacillus sp. PG-8 Isolated From Fermented Panchagavya and Its Effect on the Growth of Arachis hypogea

A natural bacterial isolate that shows multiple plant growth-promoting activities was isolated from fermented panchagavya (a mixture of five indigenous cow products). It is a gram-positive, endospore-forming bacteria identified as Bacillus sp. PG-8 by 16S rRNA gene sequencing. The Bacillus sp. PG-8 have shown multiple plant growth-promoting activities as indole acetic acid (2.78 μg/ml), gibberellic acid (0.7 mg/ml), ammonia (6.51 μmol/ml), exopolysaccharide (2.6% w/v) production, and phosphate solubilization (198.27 μg/ml). The Bacillus sp. PG-8 has ability to survive under the abiotic stress conditions such as temperature (28–46°C), pH (5.0–12.0), salt (0.5–20.0% w/v NaCl), and osmotic resistance (1–10% w/v PEG-6000). Due to its diverse characteristics, the effect of Bacillus sp. PG-8 was tested on Arachis hypogea (groundnut). The seeds treated with Bacillus sp. PG-8 demonstrated a 70% germination rate with seedling vigor indexes of 154. In pot study, Arachis hypogea growth showed 1.38, 1.38, 1.32, 1.39, and 1.52 times increase in root hair number, leaf numbers, leaf width, leaf length, and leaf area, respectively. The addition of Bacillus sp. PG-8 culture to the Arachis hypogea plant resulted in a significant improvement in plant growth. Bacillus sp. PG-8 is a spore producer with stress tolerance and multiple plant growth-promoting properties, which makes it a potential liquid biofertilizer candidate.

The study involved feeding MS improved using urea (U), chopped groundnut stover (cGS), chopped soybean stover (cSS), mineralized groundnut stover solution (mGS) and mineralized soybean stover solution (mSS) to lactating dairy cows. The feeding trial involved twelve (12) dairy cows in their second parity. Effect of supplementation with MS improved with U, cGS, cSS, mGS and mSS on milk quality was evaluated following on-station feeding trials. The study involved 22 factorial experiments within a Completely Randomised Design (CRD). Milk samples were analysed for protein, lactose, fat and solid not fat (SNF). Mean milk protein levels ranged from 3.52mg/ml to 3,73mg/ml (s.e=0.03) for milk from cows fed on MS improved using cGS and mGS respectively. Protein and Lactose were observed to be the least variable (3.64g/ml ±0.12, and 5.24g ±0.24 respectively). Average milk fat content was highest (4.78%, se=0.52) in milk from cows fed on UET treated MS and lowest (3.43%, se=0.52) in milk from cows fed on gGS protein based MS. Within legume type milk fat was higher(4.75%±1.99) in milk from cows fed on MS blended with mGS than that in milk from cows fed on MS improved with cGS (3.43%±1.99). Similar result was observed in milk fat from cows fed on MS improved with the use of soybean. Lactose in milk from cows fed on UET treated MS was highest (5.51g, se=0.061) and lowest (5.10g, se=0.061) in milk from cows fed on MS blended with cGS. Milk from cows fed on MS improved with mGS was higher (9.61p/cwt, se=0.14) in SNF and lowest (8.88p/cwt, se=0.14) in milk from cows fed on MS with cGS. The milk density values ranged from 32.65sg, se=0.53 for milk from cows fed on UET treated MS to 30.42sg, se=0.053 for milk from cows fed on MS blended with cGS. Milk components were higher when cows were fed on MS improved using mineralized legume stover solutions.

Genetic improvement of peanut (Arachis hypogea L.) genotypes by developing short duration hybrids

Peanut, the only cash crop of rainfed areas of Pakistan, is facing immense challenges due to global warming. Climatic factors particularly the temperature fluctuations and rain pattern shift significantly impact the production and yield of peanut and unavailability of resilient varieties exacerbate this impact. To deal with the cropping pattern change and yield losses, due to climate vagaries, a study was conducted to develop early maturing hybrids using line into tester mating design. The F1 hybrids from the parental lines were produced in the year 2018 using Line × Tester mating design and then grown in the field in the year 2019 for further evaluation. The hybrids were evaluated based on the early maturity and yield-related attributes in comparison with the parental lines. Based on the general combining ability estimate, line V-3 (Golden), was found as best parent with highly significant values for plant height, days to peg formation, days to maturity, number of pegs per plant, number of pods per plants, number of seeds per plant, 100 pod weight 100 seed weight. Similarly, tester V-7 (PI 635006 01 SD) showed highly significant results of GCA for days to germination, day to 50% flowering, plant height, days to peg formation, days to maturity, number of pegs per plant, number of pods per plants, number of seeds per plant, 100 kernel weight, shelling percentage. All the combinations were evaluated for specific combining ability and significant results were observed for V-3 × V-4 (Golden × PI 619175 01 SD) and V-1 × V-6 (BARI-2000 × PI 564846 01 SD) by developing or maturity and yield-related attributes. The hybrid combinations V-3 × V-5 (Golden × PI 635006 01 SD) followed by V-3 × V-6 showed highly significant results for mid parent heterosis and better parent heterosis for days to 50% flowering, plant height, days to peg formation, number of pegs, days to maturity, number of mature seeds per plant, shelling ratio, 100 pod weight and 100 kernel weight. These parents and hybrid combinations with early maturity genes and high yield attributes can further be used for the development of short duration variety.

Soil Hydraulic and Strength Parameters as influenced by various Mechanized Rainwater Conservation Practices in Rainfed Groundnut Crop

In India, rain fed agriculture constitutes to 60% of the net cultivated area and accounts for nearly 44% of the National food basket. 54.6% of the total workforce is engaged in agricultural and allied sector activities (Census, 2011) and accounts for 17.8% of the country’s Gross Value Added (GVA) for the year 2019-20. Rain Water Harvesting (RWH) is a low-cost, easy-to-use, environmentally friendly way to recover a large part of this lost water. In India, the rainfed agriculture constitutes 60% of the total net sown area and Andhra Pradesh constitutes nearly 57% net sown area under rainfed agriculture. Groundnut (Arachis hypogea) occupies nearly 28.3% of the cultivated area under oil seed crops in India and the area under groundnut in the Country is 5.40 Mha with a total production of 6.57 Million Tonnes (MT) and with the productivity of 910 kg ha-1. The area of groundnut crop in Andhra Pradesh is 7.47 Lakh ha whereas Ananthapuramu District occupied 6.71 Lakh ha. The study was carried out under different surface and subsurface rainwater conservation practices with the objective to study the soil hydraulic and strength parameters viz., soil moisture content in frequent intervals at 10 cm, 20 cm, 30 cm depth and bulk density, particle density and porosity at 20 cm depth. From the study, it was observed that, highest soil moisture content was observed in subsoiling at 1 m distance + broad bed and furrow system treatment at three different soil sampling depths of 10 cm, 20 cm and 30 cm as 25.40%, 31.20% and 27.50%, respectively at 40 Days After Sowing (DAS) and 29.74%, 34.71% and 22.38%, respectively at 80 Days After Sowing (DAS). The lowest bulk density and highest soil porosity were observed as 1.52 g cm-3 and 32.7% in subsoiling at 1 m distance + broad bed and furrow treatment than other practices.

Production, Quality and Acceptance of Tempeh prepared using Dolichos lablab (Indian bean )Legume

Tempeh has been one of the most widely accepted fermented products and usually produced by fermenting soybeans inoculated with Rhizopus oligosporus / Rhizopus oryzae. Tempeh could be prepared with legumes other than soybean thereby increasing the acceptability and digestibility of the common legume. Dolichos lablab is a herbaceous plant with high nutritional benefits and still under-used in various countries because of anti-nutrient factors, such as enzyme (trypsin, chymotrypsin, amylase) inhibitors, phytic acid, flatulence factors, etc. A processing technique that removes anti nutritional factors to safe level will improve the nutritional quality of this legume. The purpose of this study is to prepare and standardize tempeh using fresh Dolichos lablab and Arachis hypogea in 75:25 ratio and to evaluate the physio-chemical, nutritional and organoleptic quality of tempeh and its value added products viz., tempeh fry and tempeh gravy The quality analysis of this tempeh had 50.03 per cent of moisture, 20.13 g of carbohydrate, 19.37g of protein, 4.48 g of fat, 3.00 g of dietary fiber. On comparing the fresh tempeh, protein content of dried tempeh has increased considerably by 41.24 per cent and in the value added product viz., tempeh gravy and tempeh fry, protein content has increased by 16.67per cent and 5.09 per cent respectively. There was 100 per cent removal of anti nutritional factors viz., tannin and phytic acid due to various processing techniques. The overall acceptability of tempeh products was highly acceptable with score point of 8.0 ± 0.5 /9.0 and 7.5± 0.5 /9.0 for tempeh fry and gravy respectively. The unit cost production of 200 g of tempeh was Rs.50.00 only.

Optimum Time and Temperature for Biodiesel Production using Melon (Cucumeropsismannii), Groundnut (Arachis Hypogea), and Soybean (Glycine max)

This study investigated the optimum condition for biodiesel production at varying temperatures and time using melon (Cucumeropsismannii), groundnut (Arachis hypogea), and soybean (Glycine max) seed oils. Oil was extracted from Cucumeropsismannii, A. hypogea, and G. max using n-hexane(67.7-69.2oC) as the solvent. Biodiesel was produced from three different seed oils at varying temperatures of 65oC, 55oC, and 45oC at varied durations of 60mins, 50mins, and 40mins. The best percentage yield was obtained at 65oC for the duration of 60 minutes. The transesterification process was not complete at 40 min; however, at 50 min the process was completed. The process also remained incomplete at 45oC.The maximum percentage yield of biodiesel obtained through transesterification was 90.83% for G. max, 78.00%for A. hypogea, and 77.58% for Cucumeropsismannii seedoils. Fuel properties of biodeisels, such as kinematic viscosity, pour point, carbon residue, cloud point, water content, flash point, cetane index, and sulfated ash, were examined. The flashpoint, carbon residue, kinematic viscosity, and water content of biodiesels were within the standard specified for petrol diesel; however, cloud point and pour points of this product were found to be greater than that of petrol diesel. The cetane index of biodiesels was lower than the standard specified for petrol diesel. Additionally, the samples were not found to contain sulfated ash. Therefore, Cucumeropsismannii, A. hypogea), and G. max are goodsources of biodiesel production.&#x0D; Keywords&#x0D; biodiesel, energy, environment, fuel properties, renewable fuel&#x0D; Copyright (c) The Authors

Effect of gypsum application on yield performance of groundnut (&lt;em&gt;Arachis hypogea&lt;/em&gt; L.) Varieties in Kilinochchi district, Sri Lanka

Groundnut (<em>Arachis hypogea </em>L.) is an important oil crop grown in Sri Lanka. Application of fertilizer is substantially contributing to the yield increment; however improper management of fertilizer is the specific drawback in quality and quantity in groundnut. Therefore, the application of balanced fertilizer and minerals play an important role in the cultivation of groundnut. An experiment was conducted at the Department of Agronomy, Faculty of Agriculture, Kilinochchi to assess the effect of different rates of gypsum application on yield performance of groundnut varieties from January to May 2019. Two-factor factorial experiment was conducted in Randomized Complete Block Design (RCBD) with three replications. Four different rates of gypsum application such as 0 kg/ha (T₁ - Control), 75 kg/ha (T₂), l25 kg/ha (T₃), and 175 kg/ha (T₄) were used as the first factor and five groundnut varieties, namely Tissa (V₁), Lanka Jumbo (V₂), Tikiri (V₃), Indi (V₄), and ANK G1 (V₅) were used as the second factor. All the agronomic practices were done according to the recommendations of the Department of Agriculture. The yield parameters were recorded, and the shelling percentage was calculated. Data were analyzed using SAS 9.1 package to perform ANOVA. The best treatment was identified through the means separation using Duncan’s Multiple Range Test (DMRT) at p = 0.05. The yield parameters of fresh and dry weight of pods / plant, hundred pods and seeds weight, number of mature and immature pods and total yield were higher in gypsum appliedtreatments rather than control and the highest in T₄ (175 kg/ha gypsum) treatment. All the yield parameters were significantly different in Lanka Jumbo and ANK G1 from other varieties. However, the number of mature pods and shelling percentage were similar among the varieties. The highest shelling percentage (96 %) was recorded in Lanka Jumbo under 175 kg/ha gypsum application (T₄). The highest yield parameters were recorded in Lanka Jumbo variety, whereas the lowest was in ANK G1. There was no interaction effect among gypsum application and varieties in the yield parameters. From this study, it can be concluded that the application of 175 kg/ha gypsum (T₄) to the variety of Lanka Jumbo (V₂) can be selected as suitable treatment combination to obtain the substantial yield from groundnut in <em>Yala </em>season.
