Peanut Pods (Arachis hypogaea L.) In Ex-Mining Limestone Soil Enriched with Indigenous Bacteria

Pioneer plants are found in the former limestone mining area, and there are bacteria in their root systems. These bacteria can be used as biofertilizers. This study aims to find out the use of indigenous PGPR in ex-mining limestone land to be able to increase the yield of pea (Arachis hypogaea L.) var. Tuban. This research was an experimental study with 5 treatments applying indigenous PGPR at concentrations of 0%, 25%, 50%, 75%, and 100% and consist of 5 replications. Stages of research include planting peanuts (Arachis hypogaea L.) var. Tuban by adding indigenous PGPR with the same dose and source in an environment with sufficient sunlight. The parameters observed were biomass, pithy weight, empty pod weight, wet weight, dry weight, pH, and temperature of the planting medium for peanuts. In this study, the results showed that the concentration of PGPR 25% had a significant effect on the dry weight of peanuts and doesn’t had significant effect on biomass. Meanwhile, the provision of PGPR with different concentrations did not have a significant effect on the temperature and pH of the lime mining soil planting media

Abstract The effectiveness of a low rate of lime slurry for peanut (Arachis hypogaea L.) production was evaluated on four Coastal Plain soils of southeastern Alabama. The four experimental sites were selected on farmers' fields because of their low soil pH and low exchangeable Ca. Lime was applied just prior to planting at a 560-kg/ha rate and at the recommended rate; lime sources included a slurry, an equally-fine dry limestone, and an agricultural-grade limestone. Soil pH and exchangeable Ca of the Ap horizon were measured by depth increments when crop was harvested. Lime slurry and dry lime at equivalent rates had identical effects on soil pH and peanut yields. The 560-kg/ha rate was inadequate for maximum peanut yields on Ca-deficient soils. The recommended rate of agricultural-grade limestone was more reactive than the low rate of lime slurry, and it also produced higher peanut yields.

The present study was accomplished to find out the effects of salinity on germination, growth, physiological and biochemical processes of two different groundnuts (Arachis hypogaea L.), varieties viz., Dacca-1, and Zhinga groundnut. The experiments consisted of five salinity treatments viz., control (no salinity), 3, 6, 9, and 12dS/m during germination and vegetative stage of groundnut varieties. Results showed that germination percentage of both the groundnut varieties was significantly decreased with the increase of salt concentration. During the germination stage, maximum shoot and root length, shoot and root fresh weight and shoot and root dry weight of groundnut varieties were recorded from Zhinga groundnut variety at salt stress. The same result occurred during the vegetative stage of Dacca-1 variety while the Zhinga groundnut variety showed maximum parameters than Dacca-1. Fresh weight, as well as dry weight, of shoots and roots of both the groundnut varieties was also decreased with the increase of salt concentrations while leaf proline concentrations were increased among these varieties. Salinity caused significant (P<0.001) reduction in chlorophyll a, chlorophyll b, and total chlorophyll content in both the genotypes. Between two genotypes, Zhinga groundnut recorded higher chlorophyll a, chlorophyll b and total chlorophyll content than Dacca-1. From the studies, it is concluded that the groundnut genotype Zhinga was identified as the tolerant genotype to salt stress than Dacca-1. Overall results indicate that high salinity condition is not suitable for growing the groundnut.

A field experiment was conducted at Agronomy research farm, S.K.N. College of Agriculture, Jobner during kharif, 2015 in order to evaluate the performance of groundnut (Arachis hypogaea L.) under varying levels of sulphur and its sources. Results of experiment revealed that CGR of crop during 0 - 35 DAS registered significant increase upto application of sulphur at 45 kg/ha. However, at later stages of growth the significant increase was noted upto 60 kg S/ha only. Application of sulphur at 60 kg/ha recorded a significant increase of 6.1 per cent in RGR over 15 kg/ha during 70 DAS – at harvest stage. Likewise, application of 60 kg S/ha also significantly enhanced the number of total and effective nodules as well as fresh and dry weight of nodules/plant and produced significantly higher pod and biological yields of groundnut (1832 and 5361 kg/ha) than 45, 30 and 15 kg/ha. Application of sulphur through gypsum recorded significant increase in plant height and dry matter accumulation/m row length at all the stages of crop over SSP and elemental sulphur treatments. The maximum CGR at all the stages of crop was recorded when sulphur was applied through gypsum. Sulphur application through SSP registered 13.9, 9.8 and 21.4 per cent increase in CGR over elemental sulphur at these stages, respectively. On the other hand, SSP and gypsum increased the RGR by 7.2 and 6.3 per cent, respectively over elemental sulphur. Gypsum as a sources of sulphur fertilization recorded the highest number of 62.30 total and 55.00 effective nodules/plant and as well as fresh and dry weight of nodules (229.87 and 102.00 mg/plant) thereby increasing to the extent of 22.1, 27.6, 23.9 and 18.9 per cent over elemental sulphur. Sulphur application through gypsum produced 13.1 and 10.2 per cent higher pod and biological yield of groundnut over elemental sulphur.

Abstract Peanut (Arachis hypogaea L.) research in Ontario, Canada has focused on the problems inherent in growing a crop in an area where it had previously not been grown. It had been observed that a significant percentage of germinating seeds developed abnormal root systems. Many of these abnormal seedlings did not emerge; others emerged but failed to produce vigorous plants. Four peanut cultivars, each from two distinct sources, commercial and hand-harvested seeds were compared on the basis of pod yield, plant stand, and percentage of plants with normal root systems. A normal root system was designated as one which had a long straight tap root with many laterals. Among all cultivars, pod yield, and plant stand from hand-harvested seed exceeded that of commercial seed. In addition, the percentage of plants with normal root systems was greater for hand-harvested seed than for commercial seed with two of the cultivars. Field grown plants of three peanut genotypes were examined to determine the relative percentages of plants with normal or abnormal root systems. An abnormal root system was classified as having a curvature of the hypocotyl or the hypocotyl and tap root or no main tap root. High percentages (50–60%) of plants with abnormal root systems were found for two genotypes and for each of the three genotypes it was determined that an abnormal plant was capable of producing approximately 50% as many pods as a normal plant. Four sources of seeds were collected for each of the three genotypes: (a) normal-rooted plants, (b) abnormally-rooted plants, (c) a random selection of plants, and (d) a random selection of plants, combine-harvested. The seeds were grown in a growth cabinet study and in two field trials. In all cases, the data were consistent in that selection for normal-rooted plants did not increase the percentage of normal-rooted plants over the random selection or the abnormal selection in the following generation. Combine-harvesting caused a dramatic reduction in the percentage of plants with normal roots. In two genotypes this reduction led to a significant yield reduction when compared to the hand-harvested selections. Seed from a commercial seed lot for one of the genotypes produced a very low percentage of plants with normal roots, which also resulted in a yield reduction. The overall results demonstrated that the use of high quality seed was an extremely important facet of peanut production in this environment and that additional research in the area of seed quality is justified.

Peanuts (Arachis hypogaea L.) are one of the major oilseed crops of the world and are an important source of protein in many countries. In this study, some nutrients and characteristics of the seeds’ oil extracted from four peanut (Arachis hypogaea L.) varieties: Line 27r (Israel), Line 9 (Malawi), Line 4 (Brazil) and Line 18 (Israel) cultivated, for first time, in Upper Egypt were subjected to the comparative assessment with control NC variety (USA). Peanut seeds are a rich source of oil content (50.45 to 52.12 g 100 g−1 dry weight “DW”). The physicochemical properties of extracted oil were investigated in this study. The obtained data showed that the ratios of saturated fatty acids ranged from 14.24 to 17.23%, and the amounts of unsaturated fatty acids ranged from 82.77 to 85.76%. Significant variations (p ≤ 0.05) of oil content, saponification value, oleic/linoleic (O/L), and oil characteristics were found. Line 9 was found to be high in oil content, while Line 27r was said to have a high O/L ratio (3.22%) and proportion of unsaturated fatty acids (85.76%).

Abstract Two virginia-type peanut (Arachis hypogaea L.) cultivars, NC 6 and NC 7, were observed to germinate slowly under field conditions. Three seed treatments (1%, 5%, and 10%) of ethrel, cis-N-((1,1,2,2-tetrachloroethyl)thio)4-cyclo-hexene-1,2-dicarboximide, were prepared with a recommended seed treatment (45% Difolitan and 25% PCNB) and dusted on the seed. The experimental design was a 2 (cultivars) × 4 (3 ethrel treatments and an untreated check) factorial in a randomized complete block with four replications. The experiment was conducted for 2 years (1980 & 1981) at two locations (Suffolk, VA, and Beltsville, MD). Factors studied were: Stand counts (10 and 14 days after planting), plant dry weight (18 and 42 days after planting), pod yield, grams/100 seed, and percentages of meat, total sound mature kernels, extra large kernels, and fancy pods. No significant differences were found among ethrel treatments for any factor, except stand counts. Plots planted with ethrel-treated seed had significantly higher stand counts at 10 and 14 days than plots not planted with ethrel-treated seed. Significant differences occurred between locations for all factors, and between years for all factors, except stand counts at 14 days and grams/100 seed. Significant differences occurred between cultivars for all factors, except plant dry weight at 18 days, pod yield, and percentage of fancy pods. These results indicate that, while stands may be improved with ethrel-treated seed, no significant effects on yield or grade factors were found.

Groundnuts (Arachis hypogaea L.) is one of the essential food commodities in Indonesia. The use of biofertilizer has been applied to various types of crops. Meanwhile, the effect of using biofertilizer-sludge biogas on groundnuts is yet unknown. This study aims to analyze the seed viability and vigour, yield productivity, the anatomical response of groundnuts, and optimum concentration that could increase the values of each parameter. Treatments given include applying biofertilizer-sludge with 15 levels of treatment concentration compared to groundnuts without biofertilizer-sludge application as a control. The land was divided into 16 beds for each treatment consisting of control, biofertilizer from 10, 15, 30 L/ha, sludge from 12, 24, to 36 ml, and variations dosage of biofertilizer and sludge combined. The parameters observed for viability and vigour include the percentage of seed germination (GP), seed vigor index (SVI) for yield, the value of harvest index (HI), dry weight of the harvest, and root-shoot ratio (R/S). Anatomical responses were observed with stem diameter, stem’s metaxylem diameter, root diameter, root’s metaxylem diameter, and seed diameter. The biofertilizer-sludge results significantly affected HI, R/S values, stem diameter, root’s metaxylem diameter, and seed diameter. This research concluded that the application of biofertilizer-sludge did not significantly affect the seed viability and vigour and the dry weight of the harvest. The application of biofertilizer-sludge in various doses of concentration resulted in a decrease in the stem metaxylem diameter and root diameter compared to the control. A total of 10 L/ha biofertilizer + 24 ml sludge was an optimum concentration to increasing HI and R/S values. For the increasing stem, root metaxylem, and seed diameter, biofertilizer 30 L/ha + sludge 12 ml, sludge 24 ml, and biofertilizer 15 L/ha + sludge 12 ml were the optimum concentrations, respectively.

Ameliorative Effect

In present study, different foliar treatments were applied on peanut to check their ameliorative effect on Fe deficiency. In hydroponics experiments, foliar applications of FeSO4, Fe-EDTA, sequestrene and ferric chloride were applied to check their effect on Fe deficiency chlorosis in two varieties of peanut already screened as BARI-2000 (Fe deficiency tolerant) and BARD-699 (Fe deficiency sensitive). Sequestrene proved to be more effective in increasing the growth of plant. Photosynthetic rate increased up to 58 and 70% in BARI-2000 and BARD-699 respectively as compared to control with foliar application of sequestrene. Similarly higher active Fe concentration was recorded in both genotypes. Up to 14 and 41% increase in active Fe concentration was observed. Various morpho physiological parameters including root length, shoot length, root fresh weight, root dry weight, shoot fresh and shoot dry weights, SPAD values, photosynthetic and transpiration rates showed that BARD-699 was more responsive to foliar applications, while foliar application of sequestrene can be used in correcting Fe deficiency in both genotypes. Active Fe was significantly correlated with different morphological parameters in both genotypes. The results of presense experiment suggested that foliar applications were helpful in correction Fe deficiency in peanut and growth can be enhanced.
