Stability analysis for traits related to seed yield in sunflower (Helianthus annuus L.)

An investigation was made to test the adaptability of twenty two hybrids along with four check hybrids for seedyield/plot(g), head diameter (cm) and hundred seed weight (g) over six environments. Environmental variances were significant for all the characterssuggesting the presence of genetic variability among genotypes over environments. The G x E (linear) were non-significant for all the characters under studied when tested against pooled deviation, indicates unpredictable performance of genotypes over the environments. The environment indicesrevealed that E2 was the most favourable environment for seed yield/plot (g), head diameter and 100-seed weight. For the stability parameter, none of the hybrid was ideal with an average adaptability for all the traits. The hybrid SVSH-473 had bi value nearer to unity (b=1), non-significant value of S2di and higher mean than the population mean indicating average stability and suitable for all environments. Based on the mean performance for head diameter the hybrid, SVSH-467 and for 100-seed weight the hybrid, SVSH-458 showed stable performance.

Productivity and nutrient use of sunflower (Helianthus annuus L.) in sequential cropping system in Vertisols

Field experiments were conducted on fixed plot for three consecutive years during 2009-12 onmediumVertisolsat Hyderabad. The experimental site was clay soil with a soil pH and organic carbon of 7.7 and 0.51 per cent,respectively. The productivity and sustainability ofrabi sunflower was assessed under three cropping sequences in rainy(kharif) and winter (rabi)seasons viz., fallow-sunflower; sunflower-sunflower and soybean-sunflower and four nutrient management practices. The kharif crops were grown as rainfed and rabi sunflower was grown with one irrigation at sowing. The highest seed yield (1412 kg/ha) of sunflower was recorded in soybean-sunflower system followed by fallow-sunflower (1185 kg//ha) system. Continuous cropping ofsunflower resulted in lowest yield (983 kg/ha). N and P uptake of rabi sunflower succeeding either soybean or fallow was higher compared to continuous cropping. Significantly higher and comparable seed yield, stalk yield were obtained with the application of recommended dose of major nutrients in conjunction with farm yard manure (FYM).

Effect of Biochar on Growth and Yield of Sunflower (Helianthus annus L.) in Non-saline Tidal Area of Bangladesh

Biochar is an organic amendment used for crop production. A piece of research work was conducted in the field laboratory of Patuakhali Science and Technology University, Dumki, Patuakhali to observe the effect of biochar on the growth and yield of sunflowers. There were four treatments as Control, 5 tons ha-1 biochar, 10 tons ha-1 biochar, and 20 tons ha-1 biochar. A significant difference was found in the plant height, number of leaves, length of leaves, number of seed head-1, head diameter, seed weight head-1, 1000 seed weight, yield, and stover yields when different biochar doses were applied. The highest plant height (181.37 cm), number of leaves (20.82), leaf length (45.84 cm), number of seed head-1 (677.13), head diameter (20.63 cm), total seed weight head-1 (68.19 g), 1000 seed weight (65.49 g), grain yield (3.42 tons ha-1) and stover yield (5.79 tons ha-1) was recorded from 20 tons ha-1 treatment. Biochar of 20 tons ha-1 could be recommended for higher growth and yield of sunflower.

Impact of front line demonstration on yield and economics of sunflower (Helianthus annuus L.) in Bihar

The frontline demonstrations were carried out in 102 farmer fields to demonstrate the impact of improvedtechnology on yield of sunflower during the Spring, 2017. Each frontline demonstration was laid out on 1 acre area, and its adjacent one acre was considered as control (farmer’s practice). The frontline demonstration comprised of two hybrids namely, KBSH-44 and KBSH-53. KBSH-53 gave higher yield than KBSH-44. The result indicated that productivity of sunflower gained under improved demonstrated technology (17.10 q/ha) was higher as compared to farmer’s practices (13.14 q/ha). The study showed that improved technology gave 30.15% higher grain yield over farmers’ practices.

Effect of Foliar Application of Boron, Zinc and Manganese on Growth, Yield and Oil Contents of Sunflower (Helianthus annuus L.)

A field trial was conducted to assess the effect of exogenously applied boron, zinc and manganese on growth, yield and oil contents of sunflower at Research Area, University of Agriculture, Faisalabad during Spring, 2019. Randomized Complete Block Design (RCBD) was used for the allocation of treatments with 3 replications. Seed was sown using dibbler on 75 cm apart ridges. Foliar treatments included T0= Control, T1= Water spray, T2= 0.6% boron (B), T3= 0.6% zinc (Zn), T4= 0.6% manganese (Mn), T5= 0.3% B+0.3% Zn, T6= 0.3% B+0.3% Mn, T7= 0.3% Zn+0.3% Mn and T8= 0.2% B+0.2% Zn+0.2% Mn). Boron, Zinc and Manganese were sprayed at 35 days and 55 days after sowing keeping Borax (H3BO3), Zinc Sulphate (ZnSo4) and Manganese Sulphate (MnSo4) as sources of B, Zn and Mn, respectively. Various phenological, physiological and agronomical traits were monitored and analysed. Spray of 0.2% B+0.2% Zn+0.2% Mn gave the high values of traits including number of achenes per head, 1000-achene weight (g), achene yield (kg ha-1), biological yield (kg ha-1), harvest index (%), oil yield (kg ha-1) and achene-oil content (%).

N2O Emissions from Saline Soils in Response to Organic–Inorganic Fertilizer Application under Subsurface Drainage

Organic fertilizer applications and subsurface drainage are two important measures for improving coastal saline soil; however, nitrous oxide (N2O) emissions from saline soil under a combination of these two measures are seldom evaluated. In this study, saline soil cultivated with sunflowers (Helianthus annuus L.) was employed as an experimental system. Prior to the experiment, the saline soils were buried with three different spacings (10 m (S1), 15 m (S2), and 20 m (S3)) of subsurface drainage pipes. The nitrogen nutrients that are needed by sunflowers came from two different nitrogen sources (organic and inorganic fertilizer), including six application schemes of either 100% organic fertilizer (100%OF), 75% organic fertilizer combined with 25% inorganic fertilizer (75%OF), 50% organic fertilizer (50%OF), 25% organic fertilizer (25%OF), 0% organic fertilizer (0%OF), and no fertilizer (CK). The results show that the cumulative N2O emissions from the treatments under S1, S2, and S3 throughout the entire growth period were 8.9–15.8, 9.5–17.5, and 10.1–17.6 kg ha−1, respectively. A smaller spacing between adjacent drainage pipes or a higher replacement proportion of organic fertilizer reduced the accumulative N2O emissions. The increased replacement of organic fertilizer decreased the soil salinity, whereas it increased the C/N ratio and total carbon content. The fertilization treatments significantly increased the nitrogen uptake of sunflower plants, with increase ranges of 18.1–47.2%, 8.6–40.5%, and 8.8–34.5% under S1, S2, and S3, respectively, compared with CK. The highest yield of sunflowers was achieved under S2 combined with 25%OF, reaching 3.82 t ha−1. Correlation analysis showed that the N2O emission flux was positively correlated with the soil salinity, crop yield, and crop nitrogen uptake, whereas it was negatively correlated with the total carbon, C/N ratio, and organic carbon content. We concluded that using 25% organic fertilizer instead of inorganic fertilizer was beneficial for reducing N2O emissions while maintaining the crop yield under subsurface drainage.

Nutritional effect of zinc and boron on growth, yield and oil content of hybrid sunflower (Helianthus annuus L.)

The experiment was conducted to assess the impactofZn and B application on sunflower growth, yield and oil content in sub-tropical condition. The experiment was laid out in randomized complete block design (RCBD) with twelve treatmentsand replicated thrice. The treatments comprised viz; T1: Without fertilizers (absolute control), T2: RDF (N80P40K40), T3: N80P40K40Zn0.5%, T4: N80P40K40Zn4, T5: N80P40K40B0.2%, T6: N80P40K40B2, T7:N80P40K40Zn0.5%B0.2%,T8: N80P40K40Zn4B2, T9:N80P40K40Zn4Zn0.5%, T10: N80P40K40Zn4B0.2%, T11: N80P40K40B2B0.2%, T12: N80P40K40B2Zn0.5%.From the experimental results recorded it can be concluded that the growth and yield components of the tested crop were significantly influenced by the application of micronutrients as compared to the control (without fertilizer) and recommended dose of fertilizer alone. Among the treatmentsapplication of N80P40K40Zn4B2foundhigher diameter of capitulum (17.72 cm), number of seeds per capitulum (763), seed weight per capitulum(48.98 g), seed yield (2563 kg/ha) and oil yield (1097 kg/ha) of hybrid sunflower (variety KBSH 78) accounting 35.49%,43.25%, 26.66%, 46.50% and 51.32% more than control.

Crop establishment and diversification strategies for intensification of rice-based cropping systems in rice-fallow areas in Odisha

Context or problemIn the Indian state of Odisha, rice-based system productivity is poor due to: (i) low rice yield in the monsoon (wet) season (2–4 t ha−1 compared to 6–8 t ha−1 in Punjab or Haryana); and (ii) limited cropping during the post-monsoon (dry) season (59% of the wet season rice area is left fallow in the dry season). ObjectiveOur study identifies strategies for increasing rice-based system productivity through: (i) alternative crop establishment methods in the wet season (Dry-Direct Seeded Rice or DSR, and mechanical puddled transplanted rice or PTR-M) to traditional methods such as broadcasting followed by post-emergence tillage (locally known as beushening) and manual random puddled transplanted rice (PTR-R); (ii) to identify rice-fallow areas suitable for pulse and oilseed cultivation in the dry season; and (iii) to evaluate the performance of short-duration pulses (green gram, Vigna radiata; black gram, Vigna mungo), and oilseeds (Brassica rapa var. toria, Helianthus annuus) in rice-fallow areas in the dry season. MethodsOn-farm experiments were conducted between 2017 and 2019 in three districts of Odisha (Bhadrak, Cuttack and Mayurbhanj) to evaluate DSR compared to beushening and PTR-R; and PTR-M compared to PTR-R and manual line puddled transplanted rice (PTR-L) in the wet season. The data from Landsat-8 Operational Land Imager (OLI) and Sentinel-1satellite sensors was used to identify rice-fallow areas, and the daily SMAP (Soil Moisture Active Passive) L-band soil moisture was used for mapping suitable rice-fallow areas for growing pulses and oilseeds. Short duration crops were evaluated in suitable rice-fallow areas. ResultsIn the wet season, DSR (range −4 to + 53%) had a significant effect on rice yield over beushening. Similarly, PTR-M consistently increased rice yield by 16–26% over PTR-R, and by 5–23% over PTR-L. In the dry season, pulse crops (green gram and black gram) performed well compared to Indian mustard under rainfed cultivation. However, under irrigated conditions, dry-season rice yield was more productive than the rice equivalent yield of green gram, black gram and sunflower. We found that 1.03 M ha (i.e., ∼50%) of total rice-fallow areas of 2.1 M ha were suitable for growing short duration green gram and black gram in the dry season. ConclusionsWe conclude that system productivity and cropping intensity can be increased by adoption of DSR and PTR-M in the wet season, and growing of green gram and black gram in the dry season. ImplicationsOdisha state can potentially produce an additional 0.67 million tonnes pulses if suitable rice-fallow areas are brought under green gram and black gram cultivation in the dry the season.

The Critical Period of Weed Control Influences Sunflower (Helianthus annuus L.) Yield, Yield Components but Not Oil Content

Field studies were conducted in the northeastern part of the Republic of Croatia to determine the influence of the critical period of weed interference on sunflower (Helianthus annuus) yield, yield components, and oil content. For this purpose, different durations of competition were established, allowing weeds to infest the crop for increasing periods of time after planting or maintaining plots weed-free for increasing periods of time after planting. The beginning and the end of the critical period of weed control (CPWC), based on a 5% and 10% loss of sunflower yield, were determined by fitting the four-parameter log-logistic equations to the relative seed yield. The total weed biomass increased progressively in relation to the increase in the competition. The beginning of the CPWC period, based on a 5% acceptable yield loss, ranged from 141 to 234 growing degree days (GDD), which corresponded to the two-to-four true leaf development stage (the V2–V4 growth stages) across both sites and years. The crop had to be kept weed-free until a period when sunflower inflorescence began to open and flower (the R4–R5 growth stage) or from 1365 to 1932 GDD. The sunflower yield and yield components varied between the years and among locations. An increasing duration of weed interference negatively affected crop height, head diameter, and 1000-kernel weight, but not seed oil content.

Conclusions. On the basis of research, the main key questions regarding the regulation of physico-chemical properties indicators for tillage and mineral fertilization systems were considered, and the effectiveness of the use of no-till technology, shallow disc tillage was proven, and the effectiveness of plowing under long-term intensive mineral load for the cultivation of sunflower and corn was substantiated on grain. The yields of sunflower and corn per grain are given on chernozem typical of intensive farming. The types and forms of manifestation, factors of reproduction and regulation of the potential and increase of effective fertility of black soil are highlighted. A set of agrotechnological measures aimed at preventing the degradation of arable black soils and protecting their fertility in agrocenoses under various agrotechnologies of growing agricultural crops is substantiated.

Once-middle amount of straw interlayer enhances saline soil quality and sunflower yield in semi-arid regions of China: Evidence from a four-year experiment

Straw deep returning as an interlayer is a novel practice to enhance soil carbon and nutrients. However, the impact of applying various amounts of straw as an interlayer on soil quality still remain unclear in the saline soil. Therefore, a field experiment was carried out over four years (2015–2018) in Hetao Irrigation District, China. The aim was to evaluate the impact of four straw interlayer rates (i.e., 0, 6, 12, and 18 Mg ha−1) applied at 40 cm depth on soil quality index (SQI) and its relationship to sunflower yield in saline soil. Our results showed that, in comparison to no straw interlayer (CK), straw interlayers applied at rates of 6, 12, and 18 Mg ha−1 improved SQI on average by 2.0, 2.7, and 3.0 times in four years, respectively (p < 0.05). This suggested that straw deep returning as an interlayer improved SQI, especially for middle and high amounts (12 and 18 Mg ha−1). Partial least squares path model (PLSPM) illustrated that the improvement of SQI was due to the high-moisture and low-salt environment created by straw interlayer in the early two years (2015–2016), while the higher soil nutrients released from straw decomposition in the subsequent years (2017–2018). The improvement of SQI contributed to sunflower yield, which was related to the decrease of soil salinity, the increase of soil moisture, soil organic carbon (SOC), total nitrogen (TN), and available nutrients under straw interlayers. The sunflower yield was increased by 8.7–13.4% under straw interlayers (p < 0.05), following the order of 18 = 12 > 6 >0 Mg ha−1. The greater increment of yield was detected during the initial phase of burying straw interlayers, which indicated that straw as an interlayer played a more important role than nutrient supply from straw decomposition. The findings highlighted that appropriate straw return amount (i.e., 12 Mg ha−1) as an interlayer is an economic practice to benefit soil quality and crop yield synchronously in salt-affected soils.

Fly Bioash Ameliorates Acid Luvisol and Increases Sunflower (Helianthus annuus L.) Yield in Field Conditions without Compromising the Risk of Radioactive Contamination

Fly bioash (FBA) as a by-product of biomass-fuelled facilities exhibits alkaline properties and is enriched with phytonutrients, thereby offering the potential to effectively ameliorate acidic and nutrient-deficient soils. However, concerns about health risks due to a potential FBA radioactive contamination are still not well studied, notably under field conditions. This study examined pH changes and concentrations of natural (238U, 232Th, 226Ra, 40K) and anthropogenic (137Cs) radionuclides after application of very alkaline (pH &gt; 12) FBA in: (i) highly acid (pHKCl = 4.1) Luvisol and (ii) sunflower (Helianthus annuus L.) seeds, grown in organic farming and rain-fed conditions. FBA (originated from a modern cogeneration, fuelled on certified deciduous forest wood chips) was applied at increasing doses; 0, 4.5, 8.6, 13, and 17.2 t/ha. After 54 months of application, FBA significantly increased soil pHKCl by up to 1.8 unit and the seed yield by 15%, compared with no amended Control, without compromising soil electrical conductivity (salinity). The activity concentrations (Ac) of all observed radionuclides, measured using high-resolution gamma-ray spectrometry, were not altered under FBA application, neither in the surface (0–30 cm) Luvisol horizon nor in the sunflower seed. Moreover, the Ac of 238U, 232Th, and 137Cs in the seed were below detection limit, whereas the Ac of 40K and 226Ra were lower by up to 2.6 and 61 times, respectively, than their corresponding Ac in the soil treatments. The radiological footprint of FBA exhibited lower Ac for most of the observed radionuclides compared with both (i) Croatian non-arable topsoils (with reductions of 238U 3.6 times, 232Th 1.8 times, 226Ra 1.7 times, and 137Cs 1.5 times) and (ii) widely used mineral N/P/K fertilisers in conventional agroecosystems (with reductions of 238U 12.5 times; 226Ra 1.3 times, and 40K 2.4 times). Our findings provide evidence that the application of FBA as a soil conditioner does not pose radiological health or environmental risks, contributing to more sustainable agri-food production and circular bioeconomy. However, it is essential to conduct further studies to comprehensively investigate the effects of FBA application on soil and crop quality across diverse environmental conditions and extended spatiotemporal scales.

AMMI analysis of genotype × environment interaction on seed yield of confectionary sunflower (Helianthus annuus L.) genotypes

In this study, 60 confectionary sunflower genotypes were grown for three successive years during kharif 2018, 2019 and 2020 to determine the seed yield stability and adaptability over years. Yield stability and adaptability wereanalysed by combined analysis and AMMI model. The significant interaction indicated that the genotypes respond differently across the different environments. In AMMI analysis, the AMMI 1 biplot showed the genotype EC734790 exhibited highest seed yield with 22.95g and high protein content of 31.23% and low oil content of 21.15% which is favoured for confectionary type of sunflower and is stable than all other varieties over all the threesuccessive years, along with this the genotypes EC 734790, EC 734831, EC 734844 and EC 734814 had higher mean yields with high main (additive) effects. The results of the study further indicated that, the stable genotypesfor seed yield over three successive years were G54- EC 734790 (22.95g) &gt;G55- EC 734831(19.57g) &gt;G56- EC 734844(18.15g) &gt;G26- EC 734814(19.38g) with the help of AMMI model of stability analysis. Hence, these genotypes would be considered as more adapted to a wide range of environments over three different years than the rest of genotypes.

INFLUENCE OF SHORT-TERM CROP ROTATIONS WITH DIFFERENT PROPORTIONS OF SUNFLOWER ON SOIL WATER REGIME

The article analyses the features of water consumption of sunflowers in short-term crop rotations. Presents the results of the 2020‒2021 research carried out in the experimental field of Kharkiv National Agrarian University named after V. V. Dokuchaev, located in the area of the Left Bank Forest-Steppe of Ukraine. The soil cover of the experimental field is represented by typical chernozem heavy loam on loess-like loam. Soil moisture was determined by gravimetric technique. Sunflower water consumption was calculated using the water balance method. The sunflower yield was recorded manually. The purpose of our research was to determine how short-term crop rotations with different sunflower saturation affect the formation of the soil water regime and the yield of the crop itself. The experimental design included five-field crop rotations with sunflower saturation of 0, 20, 40, and 60 %. The control in the experiment was a five-field crop rotation without sunflowers. It was determined that the yield of sunflower seeds depended on the variants and ranged from 3,21 to 3,57 t/ha. The increase in the share of sunflower in crop rotation was accompanied by a decrease in its yield, in particular, due to the deterioration of moisture supply. Soil moisture consumption was the highest in crop rotation with sunflower saturation of 60 % (2969 m3/ha). Against the background of reducing the share of sunflower to 40 and 20%, moisture consumption was 2713 and 2824 m3/ha. The water consumption coefficient was high due to an increase in the share of sunflowers in short-term crop rotations. It was determined that in crop rotation with sunflower saturation of 40 % the coefficient of water consumption was the lowest. At the same time, this variant has the highest yield of sunflower seeds (3,57 t/ha). Increasing the saturation of short-term crop rotations with sunflowers up to 60 % should occur under conditions of the high culture of agriculture. Therefore, ways of efficient use of soil moisture to increase the yield of sunflowers in short-term crop rotations are being developed.

The Effect of Depth of the Smart Artificial Subsurface Irrigation Pipes and the Distance on the Efficiency of the System Performance and Yield of Sunflower

A field experiment was conducted to study the effect of pipes depth and the distance between them in the smart artificial subsurface irrigation system on the efficiency of the system performance and the yield of sunflower (Helianths annuus L.), in one of the fields of Al-Raed Research Station/Ministry of Water Resources located 25 km west Baghdad for the growing season 2022. Two factors were used in the experiment, the first factor included the depths of the subsurface irrigation pipes at three levels 10, 15, and 20 cm. The second factor included the between subsurface irrigation pipes at three levels 50, 60, and 70 cm. The characters studied were soil moisture content %., irrigation water amount, cm3 h-1. depth of irrigation water added cm, plant height cm, and sunflower grain yield ton ha-1. Nested system was used according to the randomized complete block design (RCBD) with three replicates. The pipes depth was allocated to the main plot and the distance in the sub-plots. Least significant difference was used under the probability (LSD 0.05) to compare the averages of treatments. The results showed that the highest and lowest values of moisture content were 23.21 and 16.69 % for treatment depth 20 and distance 60 cm and treatment depth 10 and distance 70 cm, respectively. The highest and lowest values for irrigation water depth were 7.99 and 5.31 cm for the treatment depth 15 and distance 50 cm, and treatment depth 10 and distance 60 cm, respectively. The highest and lowest values for the amount of water consumed were 234.59 and 96.7 cm3 h-1 for treatments depth 10 and distance 50 cm, and treatment depth 20 and distance 60 cm, respectively. The highest and lowest values for plant height were 150.6 and 117.0 cm for the treatment depth 20 and distance 50 cm and treatment depth 10 and distance 70 cm, respectively. The highest and lowest values of grain yield were 4.97- and 2.62-ton ha-1 for treatments depth 20 and distance 50 cm and treatment depth 10 and distance 70 cm, respectively.

Impact of Mulch and Irrigation Schedules on Yield and Quality of Spring Sunflower in Tarai Region of Northern India

The field experiment was carried out at Forage Block, Instructional Dairy Farm, Nagla, G. B. Pant University of Agriculture &amp; Technology, Pantnagar (Uttarakhand) in spring 2019 to, study the effect of mulches and irrigation schedules on productivity and water use efficiency of spring sunflower (Helianthus annuus L.) in Mollisols of Uttarakhand (India). The experiment consisted of 03 levels of mulches i.e., control (no mulch), straw mulch @ 6t/ha and polythene mulch (black) in the main plot and 04 levels of irrigation schedules i.e., critical stages (button, flowering, and seed filling stage), 0.8, 1.0 and 1.2 IW/CPE ratios in subplots, was laid out in split-plot design with three replications. Under the application of polythene mulch, significant seed output was observed that was statistically comparable to straw mulch. Under polythene mulch, seed yield was found to be 4.6% and 18.5% greater than under straw mulch and control, respectively. The polythene mulch produced significantly higher stover yield that was non-significant with straw mulch Polythene mulch produced 8.10% and 10.4 % higher stover than straw mulch and control, respectively. Sunflower seed yield differed significantly among irrigation schedules. Irrigation applied at 1.2 IW/CPE produced significantly the highest seed yield that was 5.4, 11.1, and 14.8% greater than irrigation scheduled at 1.0, 0.8 IW/CPE, and critical stages, respectively. Among the irrigation schedules, stover yield was recorded 5.8, 8.0, and 10.8% higher under the 1.2 IW/CPE ratio than 1.0, 0.8 IW/CPE ratio, and critical stages, respectively. Overall, it is highlighted that polythene mulch gives significantly higher productivity and quality parameters. 1.2 IW/CPE ratios give significantly the highest seed yield, higher protein content and oil content.
