Effects of planting date, environments and their interaction on grain yield and quality traits of maize hybrids

Maize is one of the most important staple food crops for most low-income households in the Southern African region. Erratic and inconsistent rainfall distribution across maize-growing areas is a major threat to maize production. Late rains in recent years have forced farmers to plant later than the optimal planting dates, leading to poor maize quality being reported by industry, which raised the question of the influence of later planting dates on grain yield and quality traits of maize. Three yellow and three white maize hybrids were evaluated at three planting dates in three different production environments for three consecutive seasons using a randomized complete block design with three replications. The second and third planting dates caused a significant yield decrease of 23.37 % and 53.73 % from the first planting date across environments, respectively. Planting date three was associated with decreased grain yield, starch content, and increased protein but no significant change in fat and fiber content. Some hybrids yielded relatively well at all planting dates. In conclusion, the early planting date was the most suitable for maize grain yield and starch production in the maize-growing areas of the country. However, planting in January should be avoided at all costs, as it leads to very low yield and poor grain quality.

The interaction between the level of potassium fertilizer and planting dates also had a significant effect on grain yield, as the 200 kg K ha-1 level combined with the December 15th planting date resulted in the highest grain yield of 7.30 tons ha-1. Regarding the grains protein content in, the 120 kg K ha-1level recorded the highest percentage of 12.57%, and the November 15th yielded the highest percentage of 12.12% compared to the other planting dates.

Response of Yield and Agronomic Output of Bangabandhu dhan100 under Varying Sowing Window in Cold Prone Rangpur Region

Background: Selection of a suitable planting time is one of the key factors for obtaining a desirable rice grain yield. This study focuses on the effect of planting date on the key agronomic traits and provides useful information on optimal planting window to maximize grain yield of Bangabandhu dhan100 in the cold-prone Rangpur region, Bangladesh. Methods: The study was conducted at the Rangpur regional station farm of the Bangladesh Rice Research Institute from October 2021 to June 2022. The selected cultivar was seeded on eight different dates at a 15-day interval, starting on October 16. Time series data on agronomic parameters including seedling biomass, leaf number of seedlings and tiller number per plant were collected at a 15-day interval. Result: A good relationship was found between accumulated GDD (growing degree days) and the associated leaf number per plant and the highest leaf number was observed with early seeding. Similarly, seedling biomass yield depended on accumulated GDD and it was found to be higher at early seeding than late seeding. The tillering pattern of Bangabandhu dhan100 was influenced by planting dates and reached its peak at 60 days after planting for all seeding dates. The highest tiller number (368/plants) was found when the cultivar was seeded on December 1. Total biomass showed an increasing trend after planting and reached its maximum of 13.9 t/ha with December 1 seeding. Planting time significantly influenced the grain yields and the highest yields were observed during seeding between 1 and 16 December; yields gradually decreased with the advancement of seeding dates. This finding provided a good idea for the selection of an optimal planting time for Bangabandhu dhan100 to maximize grain in the Rangpur region, Bangladesh.

Heat unit requirement of sweet corn under different planting methods and dates in temperate Kashmir, India

In order to investigate the "Effect of Establishment method and Planting date on phenology, yield, and agrometeorological indices for sweet corn," a field experiment was carried out at the Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir Wadura, Sopore experimental farm of the Division of Agronomy, over the course of two sessions in Kharif 2020 and 2021. The experiment had two components: a distinct sowing date with a 20-day interval and two establishment methods (direct seeding and transplanting). The initial planting day was (25th of April, 2nd was 15th of May and third was 5th of June during both the years) Three replications in RCBD were confirmed. Following transplanting with the first date of sowing, direct seeding required the most days to attain different phenological stages and accumulate the most heat units. Transplanting with the initial date of sowing resulted in noticeably greater HUE, HTUE, PTUE, and HyTUE, resulting in the largest green cob and biological yield as compared to other dates of sowing and direct seeding. As a result, given the weather in Kashmir It was discovered that planting on the first day of sowing increased sweet corn yields economically.

Soybean planting date and seeding rate effect on grain yield and profitability

AbstractTimely soybean [Glycine max (L.) Merr.] planting is ideal for maximizing grain yield. However, weather conditions often limit farmers’ ability to plant timely. The objectives of this study were to (a) measure the effect of soybean planting date and seeding rate on grain yield, (b) identify the agronomic optimum seeding rate (AOSR; the seeding rate where soybean yield is maximized), and (c) compare the net economic return of the base treatment (May 10 to 31 planting date and 370,000 seeds ha−1 seeding rate) to the other treatment combinations. The experiment was conducted in 2020 and 2021 in Ohio at the Western (WARS) and Northwest (NWARS) Agricultural Research Stations with a split‐plot randomized complete block design with four replications. The whole plot factor was four planting dates ranging from April 25 through July 1, and the sub‐plot factor was five seeding rates ranging from 123,500 to 618,000 seeds ha−1. When water was not limiting, soybean planted in April and May yielded 8% to 26% more than soybean planted late June. In general, planting in May resulted in a lower AOSR (247,000 to 303,000 seeds ha−1), compared to planting in June, where AOSR ranged from 430,000 to 618,000 seeds ha−1. Comparative net economic return was the lowest (from $237 ha−1 to $938 ha−1) when soybean was planted after mid‐June at 123,500 seeds ha−1. These findings can help farmers improve soybean grain yield by adjusting their seeding rate based on planting date to maximize profitability.

Grain yield response to planting date and cutting height of the first crop in rice ratooning

AbstractRice (Oryza sativa L.) ratooning is one of the most essential production strategies to increase grain yield. Field experiments were conducted in southwestern Japan in 2021 and 2022 to determine the effects of planting date and cutting height of the first crop on grain yield. Grain yield of the second crop was higher at early planting date than at late planting date in 2021, but the yield difference was narrowed in 2022. The higher grain yield at early planting date resulted from the higher number of spikelets and percentage of filled spikelets due to the higher stubble nonstructural carbohydrate (NSC) content, leaf area index (LAI), and air temperatures. Grain yield of the second crop was higher at high cutting height than at low cutting height in 2021, but the yield difference was narrowed in 2022. The higher grain yield at high cutting height resulted from the higher number of spikelets due to the higher NSC content and LAI. In the weather conditions, grain yield had a strong positive correlation with the air temperature, which had positive correlations with the number of panicle and percentage of filled spikelets. In the stubble conditions, grain yield had a strong positive correlation with NSC content, which had positive correlations with the number of panicle and percentage of filled spikelets. Therefore, early planting, which secures high air temperatures, and high cutting height, which produces high NSC content, are recommended to increase grain yield of the second crop.

Effect of hierarchy of the production of tillers in wheat (Triticum aestivum L.) cultivar (KM5180) under the influence of planting dates

Sowing dates are an important factor in determining grain yield as they fall within the climatic changes, as the temperature plays an important role in increasing the yield. For the purpose of evaluating the planting dates during the winter season, a field experiment was conducted at Experiments Station, affiliated to the Department of Field Crops/College of Agricultural Engineering Sciences, University of Baghdad during 2020-21. The aim was to study the effect of planting dates on soft wheat cultivar (KM5180). A randomized complete block design (R. C. B. D.) was used with three replications. Sowing dates were used as main parameters viz., November 22nd (D1), December 6th (D2) and December 20th (D3). The results showed the superiority of the sowing date (D1) by giving the highest average grain yield of 5.740 t/ha as a result of the superiority of the plants of this date in the number of spikes/m2 (441.7), the biological yield (17.896 t/ha), the harvest index (32.09%) and the plant height (101.387 cm) and the weight of 1000 grains/g was 39.97 g, significantly superior to dates (D2) and (D3), which gave an average of 4.423 and 2.428 t/ha, 358.3 and 331.7 spikes/m2, 14.556 and 11.353 t/ha, 30.38 and 21.39%, 89.033 and 85.387 cm and 39.11 and 28.28 cm, respectively, The reason for the superiority was due to the appropriate environmental conditions accompanying during the growth period, including the appropriate temperature that gave the products of photosynthesis sufficient to meet the requirements to complete the stages of its growth and form the initiators of its organs in an optimal form, which was positively reflected on the components of the appointment (D1). As for the delay in the dates D2 and D3, the high temperatures coincided with the critical growth stages of plant growth, which reflected negatively on some traits. 7. Sequentially a grain/spike and (11.43, 11.54 and 11.29 cm, respectively. While date D3 was significantly superior in terms of the number of spikelets/spike with an average of (16,800) spikelets/spike over dates D2 and D1, and they gave an average of (16,300 and 16,200) spikelets/spike, respectively. In the light of the obtained results, we conclude that the shares of the total dates (D2) and (D3) reached 54% higher than the contribution of the sowing date (D1), which amounted to 46%, while the late sowing date (D3) achieved half of the share of the share in the grain yield.

Impacts of different planting times on fruit quality and some bioactive contents of different strawberry cultivars

ABSTRACT Strawberry fruit quality traits can be affected by genotype-environment interactions, which determine the consumer acceptance of fruits. This factorial experiment was based on completely randomised blocks (RCBD) with two planting dates (5 and 20 April) and cultivars (‘Albion’, ‘San Andreas’ and ‘Portola’) of strawberry with three replications, and some of pomological and qualitative factors of berry were investigated at harvest. The results showed no significant difference on fruit width, length, weight and firmness, while the plant yield and stem diameter (SD) were affected by different cultivars and planting dates. The minimum SD (19.80) was recorded in cv. ‘Portola’ in the planting date of 20 April. Although the lowest fruit yield was achieved in cv. ‘Portola’ at both planting dates, it had the highest titratable acidity (TA) (0.83%) at the first planting date (5 April). The amount of soluble solid concentration (SSC), electrolyte conductivity (EC), pH, TA and chlorophyll were not affected by cultivar and planting dates. The effect of planting dates and cultivar had no significant effect on berry colour. The highest total phenolic (275.44 mg GAE · 100 mL-1 FW) was recorded in cv. ‘San Andreas’ on the planting date of 20 April, while the lowest value (251.22 mg GAE · 100 mL-1 FW) was recorded in cv. ‘Portola’ on the planting date of 5 April. In general, it is suggested that the least fruit yield in strawberry cv. ‘Portola’ can be correlated with the least SD of the cultivar.

Economics of Potato cv. Kufri Lima under Different Planting Dates and Nitrogen Levels

The experiment entitled “Effect of planting dates and nitrogen levels on potato cv. Kufri Lima” was conducted at Research Farm of the Department of Vegetable Science, Choudhary Charan Singh Haryana Agricultural University, Hisar during winter season of 2020-21. The treatments comprising of three planting dates (25th September, 10th October and 25th October) and four levels of nitrogen (0, 75, 100 and 125% of recommended dose of nitrogen, RDN) were laid out in a randomized block design (factorial) with three replications. Results of study revealed that significantly increase in growth and yield on 10th October planting as compared to earlier and late planting. Total marketable potato tuber yield was recorded with 10th October planting with 100% RDN application (408 q/ha), closely followed by 125% RDN application (407.7 q/ha) and minimum was recorded under control. It can be concluded that 10th October with application of 100% of RDN (150 kg N/ha) provided with highest marketable yield and benefit to cost ratio (1.82). This may be due to higher marketable and total tuber yield under this treatment.

Effects of Planting Date, Cultivar and Vernalization Using Gibberellic Acid on the Severity of Root-Knot Nematode Damage to Globe Artichoke in Subtropical Sandy Soil.

Globe artichoke (Cynara cardunculus var. scolymus L.) is a new alternative crop in Florida. This long-season crop poses a very high risk of root-knot nematode (RKN) damage, the most important nematode problem in vegetable production in Florida. This study aimed to examine the impact of RKN damage on artichoke production in the subtropical climate of Florida. Treatments consisted of four cultivars ('Green Globe Improved', 'Green Queen', 'Imperial Star', and 'Opal') planted on three different dates (October 5, October 19, and November 2) in Experiment 1, and three cultivars ('Green Globe Improved', 'Green Queen', and 'Imperial Star') grown with or without vernalization using gibberellic acid (GA3) in Experiment 2. Both field experiments were conducted on sandy soil in west-central Florida during the 2020-2021 and 2021-2022 growing seasons. We collected RKN population density and gall index (GI) data to assess RKN damage. In Experiment 1, all tested cultivars showed moderate to high RKN infection in the 2021-2022 season, with 43% to 75% of roots galled. There was no effect of planting dates on RKN damage in the 2020-2021 season. However, delaying the planting date from October 5 to November 2 reduced the RKN damage while increasing the RKN population densities in the 2021-2022 season. In Experiment 2, all tested cultivars showed high RKN infestation, with more than 80% of roots galled. Vernalization by GA3 did not affect the severity of RKN damage. Our results suggest that all tested artichoke cultivars are highly susceptible to RKN in subtropical environments of Florida, raising an alarm on the risk of RKN damage to commercial artichoke production and increasing awareness about the need for RKN management.

Improving wheat productivity through integrated management of Avena ludoviciana

AbstractIn Australia, wheat planting is preferred in June compared with May to kill early cohorts of weeds before planting, particularly in fields with a history of high weed infestation. However, wheat grain yield is often reduced for June planting. This study aimed to investigate the integrated effect of planting dates (May 7, i.e., early‐planted, and June 7, i.e., late‐planted), seeding rates (100 and 200 seeds m−2), and weed control treatments (nontreated control, pyroxasulfone 100 g a.i. ha−1, triallate 800 g a.i. ha−1, trifluralin 600 g a.i. ha−1, and prosulfocarb 2000 g a.i. ha−1 + S‐metolachlor 300 g a.i. ha−1) on Avena ludoviciana (Durieu) control and wheat yield. For early‐planted wheat, the pyroxasulfone‐treated plots had a higher yield (5.5 Mg ha−1) at a low seeding rate compared with a high seeding rate (4.7 Mg ha−1). Pyroxasulfone and triallate treatments in early‐planted wheat using a low seeding rate produced a higher yield than each treatment of late‐planted wheat. In late‐planted wheat, varied seeding rates did not influence grain yield, irrespective of weed control treatments. Pyroxasulfone and triallate treatments in early‐planted wheat at a low seeding rate gave similar yields, and yield levels in these treatments were higher than trifluralin and prosulfocarb + S‐metolachlor treatments. A high seeding rate in early‐planted wheat resulted in an increased grain yield by 42%, 27%, and 28% in nontreated, trifluralin, and prosulfocarb + S‐metolachlor, respectively, compared with a low seeding rate. Weed biomass and weed seed production were lower in late‐planted wheat than in early‐planted wheat. Pyroxasulfone‐ and triallate‐treated plots accrued lower weed biomass and weed seed production than the nontreated plots. Averaged over weed control treatments, weed seed production was highest (2700 seeds m−2) in the early crop planted at a low seeding rate, which was reduced by 42% with late planting using a similar seeding rate. Averaged over weed control treatments, a high seeding rate in early‐ and late‐planted crops reduced weed seed production by 68% and 48%, respectively, compared with a low seeding rate. These results suggest that pyroxasulfone in early‐planted wheat can control A. ludoviciana effectively, limit weed seed production similar to late‐planted wheat, and prove a profitable option due to improved productivity compared with late‐planted wheat.
