Carrots are prone to impact damage during the root-stem separation stage, and it is easy to cause fruit damage due to the impact between the pull rod and the carrot. To reduce the damage of carrots harvested by pulling, the finite element method was used to study the critical velocity of carrot damage after the improvement of the pull rod (a rubber cushioning material with a thickness of 2mm, and inner diameter of 16mm, giving a 20 mm outside diameter, and elastic modulus of 100 MPa was wrapped outside the pull rod). The critical rotational speed of the disc driving the pull rods was solved by kinematic analysis of the pulling separation mechanism and impact velocity analysis of carrots. According to the nonuniform motion characteristics of the pull rod, a noncircular gear transmission device was designed, and a root-stem separation experiment was carried out. Because rubber cushioning material affected the success rate of separation and active disc rotational speed affected the damage rate of separation, the experimental factors were pull rod surface with or without rubber cushioning material and active disc rotational speed. Through the separation experiment, it was found that when the rubber cushioning material was used in the pull rod, and the conveyor belt velocity was 1 m•s-1 and the input rotational speed of the disc driving the pull rods was 180 rpm, the separation success rate of carrot was 90% and the damage rate was 5%.
The use of beneficial soil microorganisms as agricultural inputs for enhanced crop production necessitates selection of rhizosphere-competent microorganisms with plant growth-promoting (PGP) characteristics. Three strains of Rhizobium (LR-35-01, LA-17 and LB-11) and two strains of PGPRs (KB-133 and LK-791) were characterized for various PGP traits. The seed inoculation effect of these strains, either alone or in consortia was examined on growth, nodulation and yield of lentil (Lens culinaris M.) in a field experiment for two year during Rabi season of 2019-20 and 2021-22 at Norman E. Borlaug Crop Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar, India. The treatments: T1 (uninoculated control), T2 (RDF; 20 kg/ha N:40 kg/ha P2O5:20 kg/ha K2O), T3 (20 kg/ha N), T4 (40 kg/ha P2O5), T5 (KB-133), T6 (LK-791), T7 (LB-11), T8 (LA-17), T9 (LR-35-01), T10 (KB-133+LB-11), T11 (KB-133+LA-17), T12 (KB-133+LR-35-01), T13 (LK-791+LB-11), T14 (LK-791+LA-17), and T15 (LK-791+LR-35-01) were laid out in Randomized Block Design in three replications. All the strains of Rhizobium and PGPRs were found to positive for IAA and siderophore production. IAA production due to different strains ranged between 35.81 to 78.18 µg IAA ml-1 under in-vitro condition, maximum being with LA-17 strain (78.18 µg ml-1). KB-133 and LB-11 strains were strong and moderate HCN producer, respectively. All the strains solubilized the phosphorus in cultural conditions. All Rhizobium strains solubilized zinc. The results showed that different consortia inoculation of Rhizobium and PGPRs were better than their mono inoculants by producing greater plant height, plant dry weight, nodule number per plant, grain yield and straw yield. Consortia inoculants of PGPR (KB-133)+Rhizobium (LA-17) was found superior to other’s by producing maximum plant height at harvest (44.90 cm), root length at 60 DAS (9.90 cm), plant dry weight at 60 DAS (0.46 g plant-1) and at harvest (3.97 g plant-1), nodule number per plant (14.03) at 45 DAS and (18.00) at 60 DAS, nodule dry weight per plant (13.33 mg), grain yield (1420.47 kg ha-1) and straw yield (2277.03 kg ha-1). Results suggested that consortia inoculants of Rhizobium with PGPRs having various PGP traits would be an effective approach for improving yield of lentil and soil health.
Rice straw is a byproduct of rice cultivation, of which a considerable amount is burnt in India and other countries, causing environmental pollution and climate change by releasing greenhouse gases such as CO2, N2O, CH4, NOX, and CO into the atmosphere. The aim of this study was to recycle this huge amount of agricultural biomass by degrading it through microbial inoculants The present study consists of four treatments, rice straw (S), rice straw + water (SW), rice straw + water + Pusa decomposer (SF), and rice straw + water + TNAU biomineralizer (SB). Results of this study showed the accelerated decomposition process in microbial treated rice straw compared to rice straw + water (SW) and untreated rice straw (S). The distorted, rough, and porous surface structure of SEM micrograph in treatments SF and SB confirmed the ability of both the microbial consortia to decompose rice straw faster than in rice straw + water (SW) and untreated rice straw (S). EDAX spectra of elemental composition reported the carbon content in order of 33.66%, 29.75%, 13.33%, and 20.65% w/w of rice straw in S, SW, SF, and SB treatments respectively. The highest nitrogen content (0.64%) w/w of rice straw was reported in SF treatment and was followed by SB (0.61%) w/w, SW (0.45%) w/w, and S (0.43%) w/w of rice straw. Treatment SF and SB registered lower C/N ratios of 20.83 and 33.85 respectively compared to SW (66.11) and S (78.28) treatments.
Field experiments were conducted to Studies effect of Phosphorus, Chloropyriphos and Rhizobium inoculants on growth parameters, yield components and yield of chickpea during rabi season of 2020-21 and 2021-22 at students instructional farm, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur. The experiment consist of 18 treatments combinations in factorial randomized block design with three replications consisted of three levels of phosphorous (30, 60 and 90 kg ha-1), three chloropyriphos levels (0, 2.5 and 4.0 ml L-1) and two rhizobium inoculation levels (with rhizobium and without rhizobium). Chickpea variety RVG-203 was grown with the recommended agronomic practices. On the basis of results emanated from investigation it can be concluded that among the growth parameters maximum plant height at 90 DAS is 40.34 cm and 39.96, maximum number of branches is 17.48 and 17.82 during the both years of experimentation are associated with the treatment T18 [90 kg P+ 4.0 ml-1 Chloropyriphos with Rhizobium] and maximum number of nodules per plant at 60 DAS during first year is 26.53 and second year is 26.96 was associated with the treatment T15 [60 kg P+ 4.0 ml-1 Chloropyriphos with Rhizobium]. Similarly, among the yield components and productivity parameters maximum values in relation to number of pod plant-1, number of grain pod-1, 100 grain wt. (gm), grain yield (q ha-1), stover yield (q ha-1), biological yield (q ha-1) except harvest index (%) was also found in the treatment T15 [60 kg P+ 4.0 ml-1 Chloropyriphos with Rhizobium].
In order to study the influence of exogenous application of stress mitigating chemicals such as salicylic acid, thiourea and KNO3 to alleviate moisture stress in coriander to improve the morphological and yield attributes through irrigation scheduling, an experimentation was conducted at Vegetable Research Centre, Department of Horticulture, JNKVV, Jabalpur (M.P.) during Rabi season for two consecutive years (2020-21 and 2021-22). The trial was laid out in split plot design with IW:CPE (0.6, 0.8, 1.0 and 1.2) as main plot and stress mitigating chemicals (SA, thiourea and KNO3) as subplot with different concentrations. The pooled analysis carried out during the study substantiated that coriander variety JD-10 sown under IW:CPE 0.8 gave better vegetative growth and higher yield as was superior over the others. Foliar application of SA@150ppm significantly enhanced the morphological traits and yield components thus giving a maximum yield of 18.47q/ha by producing more number of umbels, umbellets and seeds per plant. Treatment combination I2C2 (IW:CPE 0.8 with foliar application of salicylic acid @ 150ppm) gave better growth as plant height reached to 106.27cm at crop harvest with 7.02 branches plant-1, maximum seed yield of 14.92 g plant-1 and highest seed yield of 19.61q/ha. Seed yield was found to be in positive correlation with number of umbels plant-1, umbellets plant-1, seeds per umbel and seed yield plant-1. Thus it can be concluded that coriander produced under optimum soil moisture with ascribed irrigation level along with suitable dose of salicylic acid is optimum for coriander production and ensures higher yield.
