Impact of eco-physiological factors on the weed seed germination and emergence: A review on its role in weed management

Dormancy is a typical feature of many weed seed populations, which makes forecasting the time and magnitude of weed emergence difficult. The mean minimum temperatures required for undergoing germination of different weed seeds varies considerably depending on the place of their origin as well as the season on which the plants grow. For instance, the temperature requirement for the germination of summer weeds was observed to be 40% higher than for the winter weeds. Decreasing the water potential from 0 Mpa (mega pascal) to -1.0 Mpa tends to reduce the germination capacity of many weed seeds with some seeds totally failing to germinate at -1.0 Mpa (Chloris truncate, Retama raetam). The effects of planting depth on seed germination and seedling growth of Aframomum citratum on varied soil types indicated that sowing depth greatly influenced the plant's cumulative germination percentage and early growth. The seeds of Sysimbrium officinale (L.), a summer annual species, displayed greater sensitivity to nitrates and lost dormancy throughout the winter. The germination of Thlaspi arvense was also discovered to be stimulated by nitrate only in the presence of light. Tilling the surface of soil has a positive impact in the weed seed germination, however if the tillage depth increases more than 9cm, it tends to lower down the germination of several weed species. However, weed seeds of Bernard grass are among the exceptions in which they germinate better at a shallow depth (2cm). The nature and the thickness of the mulching component influence the germination of weed seeds. Thicker mulches and mulching materials like pearl millet resulted in a greater suppression of the weed seed germination due to an increased allelopathic effects.

Exogenous Serotonin (5-HT) Promotes Mesocotyl and Coleoptile Elongation in Maize Seedlings under Deep-Seeding Stress through Enhancing Auxin Accumulation and Inhibiting Lignin Formation

Serotonin (5-HT), an indoleamine compound, has been known to mediate many physiological responses of plants under environmental stress. The deep-seeding (≥20 cm) of maize seeds is an important cultivation strategy to ensure seedling emergence and survival under drought stress. However, the role of 5-HT in maize deep-seeding tolerance remains unexplored. Understanding the mechanisms and evaluating the optimal concentration of 5-HT in alleviating deep-seeding stress could benefit maize production. In this study, two maize inbred lines were treated with or without 5-HT at both sowing depths of 20 cm and 3 cm, respectively. The effects of different concentrations of 5-HT on the growth phenotypes, physiological metabolism, and gene expression of two maize inbred lines were examined at the sowing depths of 20 cm and 3 cm. Compared to the normal seedling depth of 3 cm, the elongation of the mesocotyl (average elongation 3.70 cm) and coleoptile (average elongation 0.58 cm), secretion of indole-3-acetic acid (IAA; average increased 3.73 and 0.63 ng g−1 FW), and hydrogen peroxide (H2O2; average increased 1.95 and 0.63 μM g−1 FW) in the mesocotyl and coleoptile were increased under 20 cm stress, with a concomitant decrease in lignin synthesis (average decreased 0.48 and 0.53 A280 g−1). Under 20 cm deep-seeding stress, the addition of 5-HT activated the expression of multiple genes of IAA biosynthesis and signal transduction, including Zm00001d049601, Zm00001d039346, Zm00001d026530, and Zm00001d049659, and it also stimulated IAA production in both the mesocotyl and coleoptile of maize seedlings. On the contrary, 5-HT suppressed the expression of genes for lignin biosynthesis (Zm00001d016471, Zm00001d005998, Zm00001d032152, and Zm00001d053554) and retarded the accumulation of H2O2 and lignin, resulting in the elongation of the mesocotyl and coleoptile of maize seedlings. A comprehensive evaluation analysis showed that the optimum concentration of 5-HT in relieving deep-seeding stress was 2.5 mg/L for both inbred lines, and 5-HT therefore could improve the seedling emergence rate and alleviate deep-seeding stress in maize seedlings. These findings could provide a novel strategy for improving maize deep-seeding tolerance, thus enhancing yield potential under drought and water stress.

Traction resistance study of the stuff seeder SKP-2.1

The article presents the results of a study of the traction resistance of a stubble grain planter-cultivator SKP-2.1 with mass-produced standard foot coulters and experimental combined coulters of the design of the Omsk ANC. Comparative studies were carried out on an aggregate consisting of the MTZ-82.1 tractor + the SKP-2.1 seeder according to the stubble agrophone from the previous crop – wheat. The speed of the unit: 7, 9, 11 km/h. Stroke depth of working bodies: 0.04, 0.06, 0.08 m. The study of the traction resistance of the seeder was carried out using the information-measuring system EMA-PM and the strain gauge link. It was found that the traction resistance of a drill with experimental combined coulters at a speed of 9 km/h and a sowing depth of 0.04 m is 33.3 % less than that of a drill with standard foot coulters; at the same speed and sowing depth of 0.06 m, the difference was 13.8 % in favor of a combined coulter. With an increase in the sowing depth to 0.08 m, the traction resistance of the combined coulter is only 3 % less.

Emergência e desenvolvimento de plantas daninhas em função da profundidade de semeadura e intensidade luminosa

ABSTRACT Understanding weed emergence and development aspects is essential in decision-making for management strategies. The study evaluated the effects of different sowing depths and light intensities on the emergence and development of the weeds Sida rhombifolia and Senna obtusifolia under field conditions. Each species constituted an experiment, and the experimental design used was completely randomized, with four replications. The treatments were arranged in a 6 x 4 factorial scheme, with the first factor corresponding to the six sowing depths (0.5; 1.0; 2.0; 4.0; 8.0, and 12.0 cm) and the second at four light intensities (100%, 70%, 50%, and 30% of sunlight). The seedling emergence was evaluated daily to obtain the emergence and emergence speed index. The height, time to floral induction, and dry matter of plants at flowering were also evaluated. When submitted to different levels of shading, S. rhombifolia seedlings emerge up to 12.0 cm deep. S. obtusifolia seedlings emerge at all sowing depths, even when subjected to different solar radiation intensities. Seedlings of S. rhombifolia and S. obtusifolia emerge less and slower in sowings between 8.0 and 12.0 cm depth and develop better under full sunlight in sowings between 1.0 and 4.0 cm depth. Therefore, greater depths delay the development of both species, which is important information for managing these weeds.

Effect of soil type and sowing depth on the germination and early growth of two grain amaranth cultivars

AbstractGrain amaranth is a highly nutritious pseudo‐cereal with good adaptability to a range of environmental conditions and potential to be further cultivated in many areas of the world. Although the crop has good adaptability, soil type can influence crop establishment and production; thus, the objective of this study was to evaluate how cultivar, sowing depth, and soil type affect emergence and early growth of grain amaranth. A pot experiment was carried out in two runs under greenhouse conditions. The experiment was set in a randomized complete block design in a 3 × 5 × 2 factorial arrangement with three soil types (loam, clay loam, and clay) × five sowing depths (0, 5, 10, 15, and 20 mm) × two grain amaranth cultivars (Amaranthus cruentus BRS Alegria and Amaranthus caudatus Inca). Amaranthus caudatus had greater seedling height, stem diameter, number of leaves, root length, fresh weight, and dry weight compared to A. cruentus. Emergence was affected by cultivar and was 15% greater for A. cruentus. Seedling height was significantly greater at a 5 and 20 mm sowing depth. Root growth varied as a function of the interaction between soil types and sowing depths in which the longest roots were obtained when grain amaranth was sown in a loam soil at 10 mm depth. For better growth of grain amaranth, the recommended combination is A. caudatus in a loam soil at a depth between 5 and 20 mm.

Effect of Jelly and Planting Depths on the Traits of Two Barley Verities

A field experiment was conducted in two separated environments in Nineveh Governorate, northern Iraq: the first in Telkef district and the second in Mosul district. Each experiment featured the growing of two barley varieties (Var) [Local black (LB) and Local white (LW)] at different sowing depths (SD) (4 and 8 cm), as well as the addition of three levels of hydrogel (HL) (0, 100, and 200) kg.ha-1. Traits studies: plant height (PH), leaf area of the flag (LAF), spike length (SL), Spike No. m2 (NS.m2), Number of grains/spike (NG/S), 1000 weight grains (1000WG), Biological yield (BY), Straw yield (SY), Grain yield (GY), Harvest index (HI). The results indicated that the (LB) variety superiority the (LW) variety in characteristics of (SL), (NS/m2) and (GY), whereas the local white variety superiority it in characteristics of (LAF), (NG/S) and (GY) in both sites. The (SD) show that the depth (8 cm) was superior in the traits of (PH), (NS/m2), (BY), (SY) and (GY), while the depth (4 cm) was significantly superior in the trait of (1000WG) for the two experimental sites. For the two experimental sites, the treatment of adding (200 kg.ha-1) of hydrogel was superior in characteristics (LAF), (NS/m2), (NG/S), (1000WG), (BY), (SY), (GY) and (HI). The majority of the binary and triple interactions revealed substantial differences between them and for the majority of the attributes investigated, as well as for both locations.

Current Situation and Future Development Direction of Soil Covering and Compacting Technology under Precision Seeding Conditions in China

Precision seeding is an effective technical way to improve quality and reduce material costs. However, certain factors limit the development and promotion of precision seeding technology, among which the main factor is that the agronomic requirements of sowing vary significantly in different areas, and there is a lack of suitable implements; at the same time, each link among the parts interact, which brings specific difficulties to improving the operational effect. This paper summarizes the precision seeding technology from the perspective of precision seeding realization and the consistency of seed spacing and use of consistent sowing depth control technology. A detailed description is included of the precision seed-discharge technology, the smooth seed-dropping technology, and the seed falling into the seed bed with precision. The need for regulation technology for consistent sowing depth is explained from a developmental perspective. The research status of compatible sowing depth control technology is described, as used in soil covering and compacting. This paper presents the problems and future development directions of soil-covering and compacting technology under precision-seeding conditions, including developing adaptable regional soil-covering and compacting devices, improving the processing and equipment technology of enterprises, strengthening the structural optimization design of soil-covering and compacting devices, conducting research into soil-covering and compacting control methods, and promoting the intellectual development of agricultural equipment.

FORMATION OF BUSHINESS OF SPRING TRITICALE VARIETIES DEPENDING ON THE PREDECESSOR AND FERTILIZER

The article highlights the influence of precursors and levels of mineral fertilization on the formation of productive bushiness of spring triticale of different varieties. Depending on the influence of meteorological factors and weather, the influence of the studied elements of winter triticale cultivation technology, the indicators of the level of bushiness changed. The highest productive bushiness was formed by plants in the variants in which the best conditions were created for this. Triticale is an artificially bred crop that has not been studied enough in the global economy and requires research, but in Ukraine it is a well-known crop that takes its share in the overall crop structure. For example, the use of different norms of nitrogen fertilizers on the background of P60К60 contributed to an increase in the number of productive stems per unit area, and, accordingly, in the productive bushiness in general. When applying phosphorus and potassium fertilizers (P60К60), the number of productive stems did not exceed 585-591 pcs./m2, and the productive bushiness was 1.58-1.59, respectively. Triticale consumes a lot of nutrients from the soil to form a crop, which requires additional fertilization. It is not customary to apply organic fertilizers to this crop. only under its predecessors. Depending on the soil fertility, 60 to 90 kg of nitrogen, phosphorus and potassium are applied. Phosphorus and potash fertilizers are scattered under the main cultivation. And nitrogen fertilizers are divided into three fertilizing sessions during the phases of active plant growth. Experts also advise to apply superphosphate 10-15 kilograms per hectare during sowing with seeds. Triticale is very sensitive to sowing dates, which roughly coincide with the middle of the optimal sowing period for winter wheat. For sowing, it is necessary to select seeds with a germination rate of at least 92% and a purity of at least 98%. Treatment with compositions designed for winter wheat has a good effect on the yield. In most farms, the crop is sown using intensive technology in a row with the skipping of technological paths. Some farms use a cross-row or narrow-row sowing method. The seeding rate is usually between 1.5 and 5.5 million germinating grains per hectare. The recommended sowing depth is 4-6 cm, reduced on heavy soils and increased by 1-2 cm on light soils. By selecting the best predecessors, namely soybeans, sunflower and corn, we created optimal conditions for the productivity of this crop. In addition, mineral fertilizers had a positive effect on the formation of bushiness of spring triticale.

Design and Test of Sowing Depth Measurement and Control System for No-Till Corn Seeder Based on Integrated Electro-Hydraulic Drive

An electro-hydraulic profiling mechanism has been gradually applied to provide suitable downforce for a no-till row unit and to ensure the consistency of the seed sowing depth. In order to improve the control effect of the sowing depth system and solve the problems of a complex structure, scattered valve sets and equipment suitability of an existing electro-hydraulic row unit, this paper takes the 2BJ-470B no-till row unit as the carrier and innovatively designs an integrated pressure-reducing cylinder (IPRC) based on electro-hydraulic technology by analyzing the sowing depth control process of an electro-hydraulic seeder. In addition, we develop the integrated electro-hydraulic-driven sowing depth measurement and control system. Combined with the feedforward compensation PID control algorithm, the dynamic regulation of the downforce is realized with the IPRC. The field test shows that under the setting of a sowing depth of 50 mm and a vehicle speed of 9~10 km·h−1, the qualified rate of the sowing depth under the three adjustment methods of self-weight adjustment, spring adjustment and electro-hydraulic adjustment is 89.2%, 96.7% and 98.6%, respectively, and the corresponding maximum coefficient of variation of the sowing depth is 16.7%, 12.9% and 6.4%, respectively. The seed groove environmental qualification rate (SFEQ) is further analyzed in combination with the soil compaction, and the mean values of the qualification rates of the three control methods at different vehicle speeds are 88.3%, 91.6% and 98.6%, respectively. The integrated electro-hydraulic-driven row unit has significant advantages over mechanical and self-weight regulation, and its whole machine integration degree and high adaptability realize the comprehensive control of the sowing depth and soil compaction strength.

EVALUATION OF EMERGENCE AND GROWTH RESPONSE OF CYPERUS ROTUNDUS AS INFLUENCED BY SOWING DEPTHS AND WATER REGIMES

Cyperus rotundus is rapidly growing plant can quickly form dense colonies through the extensive underground system of tuber and rhizomes. It is highly competitive for resources and causes a significant yield reduction in field crops. The nonchemical method has recently been practiced to control this noxious weed species. The current study was conducted to determine the effect of sowing depths (4, 8, 12, and 16 cm) and water regimes (deficit irrigation, medium irrigation, and frequent irrigation treatments) on C. rotundus shoot growth and underground growth of tubers in pots soil. Weed emergence, i.e., mean emergence time (MET), emergence index (EI), final emergence percentage (FEP), and shoot growth traits i.e. shoot density, shoot fresh weight, shoot dry weight, and tuber growth traits i.e. tuber density, tuber weight, root density, and root weight were recorded under the completely randomized (CRD) factorial design. The greatest suppression of C. rotundus emergence and growth was found at 16 cm sowing depth. The mean emergence time (MET) of C. rotundus was increased by increasing the sowing depth. Minimum value of shoot densty (9.5 g) and tuber density (15.75 g) were recorded at 16 cm sowing depth under deficit irrigation treatment respectively.While shoot and tuber desnity traits were also drastically suppressed by increasing sowing depth at the deficit irrigation level. It is concluded that sowing depths and deficit irrigation methods can be included as a reliable approach for controlling purple nutsedge shoot and tuber growth.

Deep sowing of dry direct-seeded rice: cultivar differences in seedling establishment and grain yield

ABSTRACT Dry direct seeding of rice (DDSR) is being increasingly used in water-scarce areas across Asia. When drought occurs, deep sowing may enable germinating seeds to utilize the residual moisture below the surface. Our objective was to examine the effects of different sowing depths on DDSR crop growth. Two yield experiments, one in the Philippines and the other in Japan, were established in rainfed lowlands, but drought did not occur. Across the experiments, sowing at a depth of 6 to 7 cm reduced the percentage of emergence compared with sowing at a depth of 1 to 2 cm (25% vs. 73%), which resulted in lower yield (3.5 vs. 4.4 t ha−1). The relative yield (deep-sowing/shallow-sowing) was positively correlated with the percentage emergence under deep sowing. Cultivars with no significant yield reduction under deep sowing maintained high emergence (>30%) under deep sowing. Seedling’s ability to emerge after deep sowing greatly differed among cultivars: the percentage emergence ranging from 0% to 18% from a depth of 8 to 10 cm, and from 11% to 44% from a depth of 6 to 7 cm. An ancillary field experiment was conducted under drought during the dry season in the Philippines: deep sowing increased the percentage emergence compared with shallow sowing (41% vs. 5%), when the soil surface was severely dry. Our results suggest that choosing cultivars that can tolerate deep sowing is a prerequisite for using deep sowing in DDSR, and that future breeding of DDSR should focus on this tolerance.

FACTORS MILITATING AGAINST AGRICULTURAL PRODUCTIVITY OF CROP FARMERS IN NIGER STATE, NIGERIA

Niger State has the largest landmass in Nigeria. With 8.6 million hectares of land which represents about 9.3% of the total landmass of Nigeria, the state experiences distinct dry and wet seasons with annual rainfall varying from 1,100 mm (120 days) in the northern part to 1,600 mm (150 days) in the southern part. The vegetation, soil and weather patterns are favourable to produce a wide spectrum of food and cash crops of various types. The major crops grown in the State include rice, maize, millet, sorghum, yam, potato, soybean, groundnut, cashew, benniseed and cassava. The primary aim of this study was to investigate the factors militating against agricultural productivity of farmers in production of crops in the state. Both primary and secondary data were used for the study purposes. Descriptive statistics was used on sample of 360 crop farmers. Findings from the study indicates that fertiliser, herbicides, labour, late onset rains and high interest rates are the factors militating against the production of food crops in Niger State. The study thus concluded that, the application of inappropriate agronomic practices such as untimely planting, incorrect plant spacing, wrong method of planting, poor sowing depth, delayed weeding, ineffective pest and disease control, inappropriate use of fertilizers, untimely harvesting, use of low yielding varieties and inconsistent rainfall patterns, will always significantly reduce crop yields.

Effect of sowing depth and soil cover on Paspalum virgatum L. seedling emergence

Paspalum virgatum L. is a grass weed common in pasture and has difficult control, mainly due to its similarity to forage, is found in areas of degraded pastures in the state of Mato Grosso. The objective of this work was to evaluate seed germination and seedling emergence of razor-blade grass (P. virgatum L.) when exposed to different sowing depths. Two independent experiments were carried out, one using straw from Brachiaria brizantha cv. Marandu (Experiment I) and another from Panicum maximum cv. Mombasa (Experiment II). The treatments for both experiments were organized in a 7x2 factorial scheme, considering seven depth levels (0, 1, 2, 3, 4, 5, and 10 cm). The bottom of the pots was sealed with filter paper and gauze. The emergence of seedlings was recorded daily until 28 days after sowing. The data obtained were submitted to analysis of variance. For experiment I, there was a significant effect on the soil cover factor in relation to %E and IVE, where the use of straw was more efficient. For experiment II, there was no effect of the soil cover factor in relation to %E and IVE. The greater the depth, the lower the emergence of razor-blade grass seedlings.

Impact of the orientation of seed placement and depth of its sowing on germination: A review

Seed orientation and its impacts on germination and seedling establishment mainly depend on the type of germination (hypogeal (or) epigeal), seed size and shape. Higher germination per cent is noticed when seeds are sown in the horizontal position. Planting seeds in a downward position can lead to a variety of physiological, chemical and morphological changes in seedlings. Consequences are usually manifested as noticeable modifications in their development. Vigorous seeds have strong, resilient seedlings due to their well-balanced metabolism and coordinated subcellular activity, making them well-suited for tough environments. Proper plumule and radicle growth require additional hormones and energy to ensure seedling survival. Four necessary factors must be considered while deciding the sowing depth viz., soil moisture, optimum soil temperature, soil aeration and atmospheric humidity required for seed germination, emergence and seedling growth. Variations are observed in germination behaviour and seedling growth for different sowing depths. The necessary factors are very much important for efficient nursery seedlings production. This review looks at the effects of seed depth and orientation on the germination and growth of important agricultural, horticultural and silvicultural crops.

Seed Germination and Seedling Emergence of Lysimachia mauritiana Lam. (Primulaceae)

Lysimachia mauritiana Lam. (Primulaceae), a biennial maritime plant, is widely distributed in East Asia, the Philippines, Micronesia, Polynesia, and the Indian Ocean. Because of this species’ wide distribution in Japan, we hypothesized that it could germinate and grow even in the bare coastal areas damaged by the tsunami caused by the Great East Japan Earthquake. Thus, we aimed to evaluate the seed germination of L. mauritiana under different sowing depths, temperatures, and salinity soil conditions. The highest germination rate was obtained by sowing L. mauritiana seeds near the soil surface, with germination rate decreasing as the seeding depth increased. Lysimachia mauritiana germinated even at relatively low temperatures. Moreover, we found that L. mauritiana seeds could germinate in less than 1% salt water and in salt-accumulated soil, using soil soaked in 5% or 10% salt water. Our results therefore suggest that L. mauritiana seeds could germinate by sowing on the bare soil surfaces damaged by the tsunami.

Influence of soil compaction and moisture variation on development of sesame (sesamum indicum l.) plant in a sandy loamy soil

This study determines the influence of soil compaction on shoot, root development and nutrients uptake of sesame (sesamum indicum l.) plant in a sandy loamy soil. The research was carried out in Mokwa local government of Niger state during wet season. Three soil samples of 300g weight from the top 20cm of the soil profile were taken from college farm. The initial moisture content of the soil was determined using oven-drying method. The soil samples were air dried, large clods broken and grounded. The soil samples were then mixed to obtain a homogenous mixture of the sample. The soil moisture content was then raised to varying moisture levels of 10%, 12%, and 14% exceeding the optimum moisture content of sandy loam which is 12% moisture. Each sample was subjected to five levels of compaction energy using 0,5,10,15,20 blows of a standard proctor hammer in cylindrical cores of 17cm in height and 10cm diameter in accordance with the standard proctor compaction procedure. Four holes were made in each can and four seeds were sown in each hole to be thinned into one seed per hole (four plants in each can). The depth of sowing was one cm. The seedlings were tinned to a maximum of five (5) per core at 15 days after planting. The heights (cm) of the seedling were taken with a measuring tape at 5-days interval to 20 days after planting. The experiment was laid out in randomized complete block design (RCBD). The data collected were subjected to descriptive statistical analysis, regression analysis and analysis of variance. The results from the soil physical properties analysis shows that the soil is sandy loam with sand being 76.8 % and clay as 11.2%. The bulk average density was 1.75 g/cm3. Results obtained from the study shows that compactive efforts significantly affect plant growth and development. It also shows that as compactive effort increases, the soil bulk density and penetration also increases. The effect of number of hammer blows on soil bulk density and penetration resistance was significant. The effect of excessive moisture also affects germination and plant growth. Moderate soil compaction has beneficial effect. This is due to greater water retention. In general, it appears that there is a great potential in growing sesame on sandy loam soil, if the level of compaction is maintained at moderate level, which does not impede root development and other plant requirements.
