Prediction of Single Disc Seeding System Forces, Using a Semi-Analytical and Discrete Element Method (DEM) Considering Rotation Effects

Disc seeders are commonly used in no-till farming systems, and their performance evaluation generally rely on expensive and time-consuming field experiments. Mathematical models can help speed up force-related evaluations and improve the understanding of soil-disc interactions, to assist the performance optimisation processes. Previous analytical force prediction models of disc blades have not accounted for the free rotation aspect of the disc blade. This paper develops an analytical force prediction model from the wide blade failure theory adapted to suit rotating flat disc blades operating at different sweep and tilt angles and compares predictions with Discrete Element Method (DEM) simulations. To validate the two models, experiments were performed on a remoulded sandy soil condition using a rotating flat disc set at two tilt angles of 0° and 20°, and four sweep angles of 6, 26, 45 and 90° the 3-dimensional force components of draught, vertical and side forces were measured. Results showed a higher coefficient of determination (R2 = 0.95) was obtained with analytical model predictions compared to DEM predictions (R2 = 0.85) for their agreement with the test results. It was found that both the developed analytical approach and the DEM model can be used to predict tillage forces at different sweep and tilt angles acting on a rotating flat disc blade.

The beneficial effects of overhead shading net on fruit cracking control, productivity and quality of pomegranate fruits

A field experiment was carried out during 2020 and 2021 seasons to examine the effects of different overhead shading net colors (white and blue) on fruit cracking percentage, productivity, leaf chlorophyll and leaf mineral content, also fruit quality of M 116 pomegranate trees grown under sandy soil conditions compared with the farm treatment (coving fruits with Kraft paper) and the untreated trees (control). The obtained results showed that shading pomegranate trees with blue or white net significantly increased number of fruits per tree, the total yield (kg), fruit weight (g) and reduced fruit cracking percentage when compared with the control and farm treatments. Blue and white colors surpassed the other treatments including the untreated trees in the most parameters under investigation. Finally, it could be recommended that shading pomegranate trees with blue followed by the white one are beneficial for maintaining good fruit quality with high yield. Additionally these treatments reduced the fruit cracking percentage compared with the other ones.

EFFECT OF VERMICOMPOST-TEA AND PLANT EXTRACTS ON GROWTH, PHYSIOLOGICAL, AND BIOCHEMICAL TRAITS OF LETTUCE (LACTUCA SATIVA L.)

The vermicompost and exogenous plant extracts as a foliar application can provide as an alternative means to enhance the growth and yield of leafy vegetable crops under low-fertility soil conditions. The objectives of the recent study sought to characterize the effect of vermicompost tea in combining some natural plant extracts to enhance the growth and yield of the lettuce plant. A study on lettuce (Lactuca sativa L.) took place during two successive seasons, in 2018–2019 and 2019–2020, using foliar spray— vermicompost-tea rates in combination with rosemary leaf extract (RLE) and eucalyptus buds extract (EBE). It sought to determine the effects on growth, yield, and some physiological and biochemical traits of lettuce (cv. ‘Dark Green’) grown on sandy soil with drip irrigation. The experiment employed the split-plot design, with four rates of vermicompost tea (0%, 5%, 10%, and 20%) as main plots and three plant extract levels (without, RLE, and EBE) as subplots. The vermicompost tea and plant extracts increased the growth characteristics, photochemical activity, photosynthetic pigments, relative water content, membrane stability index, excised leaf water retention, vitamins C and E, and total soluble solids in lettuce plants compared with the untreated control plots. The interaction and combined application of vermicompost tea (20%) and RLE proved most effective in enhancing the growth and yield traits and physio-biochemical properties in lettuce. Therefore, the integrative application of vermicompost tea (20%) with RLE comes highly recommended for growing lettuce in sandy soil conditions.

The result proved that 142 kg N ha−1 with yeast treatment was the best treatment for three Canola genotypes. Also, the result showed that seed yield was positively correlated with Chl. a/b ratio, plant height, number of branches/plant, number of pods/plant, and number of seeds/pod, and a strong negative correlation was detected between seed oil percentage when the amount of nitrogen fertilization applied without or with yeast extract is increased.

Influence of Cyanobacterial Inoculum on the Growth Features and Yield of Peanut Plants in Sandy Soil

Two field experiments were conducted at the Ismailia Agricultural Research Center Station during the summers of 2021 and 2022 to study the effects of cyanobacterial inoculation (Anabaena oryzae and Nostoc mascarum) on peanut plant growth, yield, and certain soil biological activities under different nitrogen fertilisation ratios and conditions. There are three applications: soil drenching, cyanobacterial seed coating, and foliar spray with cyanobacterial strains.The findings demonstrated that cyanobacteria inoculation of peanut plants generally improved peanut plant growth, resulting in significantly higher peanut and grain yields than uninoculated treatments. When compared to other tested treatments and types of applications, N. mascarum + 75% (N) produced the highest peanut yield and plant characteristics, followed by A. oryzae + 75% (N) in soil drench application. Overall, cyanobacteria increased the amount of N, P, K, and Ca in peanut plants. Cyanobacteria inoculation improved soil fertility by increasing total bacterial and cyanobacterial count (CO2) evolution, and indole acetic acid contents in the peanut rhizosphere. In general, peanut growth in sandy soil conditions can benefit from cyanobacteria inoculation with 75% nitrogen amounts.

In general, cyanobacteria inoculation with 75% nitrogen amounts can benefit under peanut growth in sandy soil conditions.

The Pyla-1 Natural Accession of Arabidopsis thaliana Shows Little Nitrate-Induced Plasticity of Root Development

Optimizing root system architecture is a strategy for coping with soil fertility, such as low nitrogen input. An ample number of Arabidopsis thaliana natural accessions have set the foundation for studies on mechanisms that regulate root morphology. This report compares the Columbia-0 (Col-0) reference and Pyla-1 (Pyl-1) from a coastal zone in France, known for having the tallest sand dune in Europe. Seedlings were grown on vertical agar plates with different nitrate concentrations. The lateral root outgrowth of Col-0 was stimulated under mild depletion and repressed under nitrate enrichment. The Pyl-1 produced a long primary root and any or very few visible lateral roots across the nitrate supplies. This could reflect an adaptation to sandy soil conditions, where the primary root grows downwards to the lower strata to take up water and mobile soil resources without elongating the lateral roots. Microscopic observations revealed similar densities of lateral root primordia in both accessions. The Pyl-1 maintained the ability to initiate lateral root primordia. However, the post-initiation events seemed to be critical in modulating the lateral-root-less phenotype. In Pyl-1, the emergence of primordia through the primary root tissues was slowed, and newly formed lateral roots stayed stunted. In brief, Pyl-1 is a fascinating genotype for studying the nutritional influences on lateral root development.

KAJIAN SIFAT FISIK, KIMIA, DAN BIOLOGI PADA TANAH BERPASIR DI BEBERAPA WILAYAH INDONESIA

The growth, development and yield of plant production are influenced by soil properties, both physical, chemical and biological properties of the soil. The physical properties of the soil include texture, structure, consistency, soil moisture (the ability of the soil to hold water) and soil permeability. Soil chemical properties include soil pH, cation exchange capacity and nutrient content. Nutrient content, consisting of mineral and organic content including nitrogen, phosphorus, potassium and other materials. Biological properties of soil are microorganisms that decompose organic matter that live in the soil. To get optimal yields on sandy soil, a solution is needed to solve the problem of physical, chemical and biological properties of sandy soil. This study uses secondary data aimed at knowing the physical, chemical and biological conditions that exist in several coastal areas in Indonesia. The results obtained treatment recommendations to improve the physical, chemical and biological conditions of sandy soil so as to produce optimal plant production. Based on the data obtained, to improve the condition of the sandy soil, several soil amendments can be used, including using compost, manure, biochar, and nitrogen fixing. The results showed that the addition of soil amendments improved soil quality, especially on the physical properties of the soil where in sandy soil the most important thing was the ability of the soil to hold water and maintain available nutrients in the soil. The most important soil chemical properties are the availability of nutrients in the soil. The responses obtained vary, especially in sandy soils and depend on the commodity of the plant.

Effects of Nitrogen and Phosphorus Application on Growth and Root Nodules of Mungbean under Sandy Soil Conditions

Legume production under infertile sandy soil may be limited by low nitrogen (N) and phosphorus (P) availability in the soil. A study was conducted to assess the effects of N and P on growth, yield, and root nodules of mung bean under sandy soil conditions. Two pot experiments were conducted under a greenhouse environment and were laid out in a completely randomized design (CRD) with five replications. Experiment 1 consisted of two types of soils (sandy and loamy sand) and two P application rates at 0 and 13 mg P kg-1. Experiment 2 consisted of 10 fertilizer treatments that included two N treatments of 0 and 53 mg N kg-1 in combination with four P treatments of 0, 17, 34, 68 mg P kg-1, P only at 17 mg P kg-1, and a cattle manure that was applied at a rate of 5 t ha-1 which was equivalent to 52:07:56 (N:P:K mg kg-1). The results showed that crop growth and root nodules improved with P application in the loamy sand soil (containing medium P), but not in the sandy soil (containing low P). Nitrogen application also improved the crop growth and grain yield significantly in loamy sand soil. However, N application suppressed root nodule formation, an effect that was significant for the N2 fixation of the crop. Increase in the P rate did not alleviate the inhibitory effect of N on nodule formation. Since N and P fertilizer had opposite effects on root nodules, interactions between N and P need to be further investigated when considering the economic benefits of using these fertilizers.

IMPROVE WHEAT PRODUCTIVITY BY USING A COMBINATION OF MINERAL NITROGEN, ORGANIC AND BIOLOGICAL FERTILIZERS UNDER NEW SANDY SOIL CONDITIONS

Two experiment were conducted among two successive winter seasons (2019/2020 and 2020/2021) at Ismailia Research Station, Ismailia Governorate. The experiments were designed to improve wheat productivity by using a combination of mineral nitrogen, organic and biological fertilizers under new sandy soils conditions. A number of sixteen treatments designed by using recommended dose of nitrogen (Ammonium nitrate) or its half, organic fertilizer (Farm yard manure), grain inoculated with SWERI inoculum asbiofertilizer (Azotobacter chroococcum, B. megatheriumand B. circulant), and Streptomyces luteogriseus. The experimental results showed that the cultivated soil was belongs to sandy soil type and was poor in each of NPK elements, with low rate of each of microbial counts and dehydrogenase activity before planting. These parameters were improved after cultivation of wheat inoculated with biofertilizers and organic fertilizer compared to before planting. This was obvious when plant heights and weights of each of plant sample, straw, grains, ears and hundred wheat grains were estimated. It was also noted that nitrogen content and protein percentages in wheat grains as well as straw were improved. Treatment No. 16 consists of SWERI, and actinomycetes inoculums, as biofertilizers, and organic fertilizer combined with 50% of recommended dose of mineral nitrogen was the most effective ones compared to each of blank (unfertilized soil cultivated with un-inoculated grains, T01)or control (soil fertilized with the recommended of mineral nitrogen and cultivated with un-inoculated grains, T02). This was reflected by increasing the expected wheat yield obtained among treatment No. 16. This treatment was also gave the highest yield amounted of grains and straw which approximately an average of 19.1 Ardab per Feddan, while each of blank and control gave 7.25 and 12.8 Ardab per Feddan respectively. As a conclusion, treatment contained the SWERI and actinomycetes inoculums, organic fertilizer and 50% of recommended dose of mineral nitrogen has led to stimulate the growth of wheat plants in sandy soils, which promises the possibility of expanding the cultivation of such soils with wheat. Therefore, one can recommend with these experimental findings, which may contribute in a large and effective way to bridge the food gap, especially with the continuous increase in population numbers

RESPONSE OF SUGAR BEET TO SANDY SOIL AMENDED BY ZEOLITE AND POTASSIUM SULFATE FERTILIZATION

Two field experiments were carried out on a private farm at Wadi El-Natrun (latitude of 30.48° N and longitude of 30.50° E), Beheira Governorate, Egypt, in the 2019–2020 and 2020–2021 seasons, to find out the effect of adding zeolite as a soil conditioner and potassium fertilizer on growth, yield, and quality of sugar beet crop (Beta vulgaris L. var. saccharifera) grown in sandy soil conditions. The present work included 12 treatments, which were the combinations of four zeolite levels (Zero, 476, 952, and 1,428 kg ha-1), and three levels of potassium in the form of potassium sulfate (119, 178.5, and 238 kg K2SO4 ha-1), which were added as a soil application. The treatments were arranged in a complete block design in a split plot with four replications. The results showed that higher values of the photosynthetic pigments, root diameter, fresh and foliage weights plant-1, as well as, sucrose and extracted sugar percentages, quality index, yields of the root, top, and sugar ha-1, were obtained by adding 1,428 kg zeolite, compared with the other levels of zeolite, in both seasons. However, sodium, alpha-amino N contents in the root, and sugar lost to molasses% were insignificantly affected by zeolite rates in both seasons. Application of 238 kg K2SO4 ha-1 significantly resulted in the highest values of photosynthetic pigments, root dimensions, sucrose%, and root potassium content. In addition, extracted sugar %, quality index, root, top, and sugar yields ha-1 were increased compared with the other lower K-sulphate levels in both seasons. On the contrary, sugar lost to molasses% was insignificantly affected by applied potassium sulfate in both seasons. The maximum values of root diameter, fresh weight, yields of root and top ha-1 in both seasons, and also sugar yield in the second season were produced from the interaction between applying 1,428 kg zeolite and 238 kg potassium sulfate ha1.
