`Chandler' strawberries were planted on four dates to ascertain optimum planting time under central Arkansas conditions. Greenhouse-rooted plugs were planted in four replications in a randomized complete-block design. Each replication was planted in double rows 6 m long on beds with 1.4-m centers. Plots were established on 9/28, 10/7, 10/26, and 11/5. Number of branch crowns, yield, and number of runners/plant indicated that the earliest planting date was too late, and thus, the optimum date was missed. Equivalent yields of 16,173 kg·ha–1 were obtained from the earliest date, dropping to 8539 kg·ha–1 when planted 10 days later.

Crop management like planting time is a crucial factor for maximizing yield especially for seed production. Seed production of carrot is greatly influenced by temperature as it requires adequate periods of cool temperature (vernalization) for flowering and seed production. To find out optimum planting time of carrot steckling for quality seed production the experiment was conducted at the Field Laboratory of Horticulture Farm, Bangladesh Agricultural University, Mymensingh during the period from October 2015 to May 2016.Three planting time viz. 05 January, 15 January and 25 January on the seed production of three carrot varieties viz. BA (Brasillia Agroflora), PA (Prima Agroflora) and NK (New Kuroda) which constituted 9 treatment combinations were included in the experiment. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Planting time had significant effect on most of the parameters studied. The January 05 planting of steckling gave the highest seed yield (527.92 kg ha-1) and the lowest was in January 25 planting of steckling (314.75 kg ha-1). Among the varieties BA gave the highest seed yield (448.73 kg ha-1) and the lowest yield for New Kuroda (395.35 kgha-1.) Considering interaction of planting time and variety the highest seed yield (572.37 kg ha-1) was obtained from the treatment combination of early planting (05 January) with the variety of BA and the lowest (279.77 kg ha-1) was recorded from the late planting (25 January) in variety PA. Hence, BA carrot variety planting on 5 January may be recommended for carrot seed production in Mymensingh region in Bangladesh. Bangladesh Agron. J. 2020, 23(2): 23-34

An experiment was conducted at the Horticulture Farm of the Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, Bangladesh during the period from November, 2018 to April, 2019 to study the effects of planting time and spacing on the growth and yield of carrots under dry land condition at BINA, Mymensingh. Five different planting times viz. November 10, November 20, November 30, December 10 and December 20 and four different spacing’s of 25× 20 cm, 20× 20 cm, 15× 15 cm and 10× 10 cm were used . This experiment was laid out in randomized complete block design with three replications. Planting time showed significant effects on the growth and yield of carrot in respect of plant height, number of leaves, fresh and dry weights of leaves and roots, length ad diameter of roots, gross and marketable yields of carrot. The highest marketable yields (39.70 t/ha) was obtained from November 20 planting, whereas the lowest yields (25.02 t/ha) from December 20 planting. Plant spacing also significantly influenced on all the mentioned parameters. The highest marketable yields (34.95 t/ha) was observed from the closest spacing of 10× 10 cm. In respect of combined effect, November 20 planting with the closest spacing of 10× 10 cm produced significantly the highest marketable (42.29 t/ha) yields of carrot. Res. Agric., Livest.

June July

Planting of kenaf usually commences from March - April as these months mark the onset of the rainy season in Nigeria. On the contrary, it is now difficult for anyone to predict when rain start due to climatic variation. Hence, field experiments was conducted between 2015 and 2016 to determine the appropriate time of sowing kenaf that will optimize its yield potential in South Western Nigeria. As a result of delay in the commencement of rain, planting did not start until May. Hence, kenaf seeds were sown in May, June, July and August at 30 days interval in each year. The experiment was a 4 × 2 factorial laid out in a randomized complete block design and replicated three times. The result indicated that the highest fibre yield (1.00 t/ha) was from the kenaf sown in June irrespective of the year, but not significantly different from the one sown in July (0.98 t/ha). On the other hand, kenaf sown in July had the highest seed yield (2.28 t/ha) with the lowest seed yield (1.04 t/ha) obtained in May followed by August (1.19 t/ha). The experiment conclusively affirm June for sowing of kenaf for fibre cultivation and July for seed production. Keywords: Planting date, kenaf, fibre and seed yield

Abstract Three studies were conducted at 3 SD sites (Delmont, Garretson, and Sinai) to evaluate insecticide application rates and techniques (hand and in-furrow) for control of NCR and WCR larvae. A randomized complete block design with 4 replications was used in these studies. Individual treatment plots were single 15.25 m long rows spaced 96.5 cm apart. Insecticide granules were applied with modified, ground-driven Noble metering units mounted on a specially-adapted Kinze 4-row corn planter. Metering units were calibrated on the planter prior to insecticide applications. Banded treatments were applied in an 18 cm swath in front of the furrow-closing wheels, and incorporated by the wheels and drag chains. In-furrow applications consisted of directing granules immediately between double disk furrow openers. Corn was seeded at 23,000 kernels per acre at all locations. Five roots per replicate were dug for each treatment. Roots were then washed, examined for feeding damage, and rated using the Iowa 1 to 6 scale.

AbstractThe influence of chilling period hours and accumulative photo-thermal unit at different base temperatures, 10, 11, 13, 15, and 18 °C, on the flowering of strawberry was examined in Sana’a University-Yemen during two seasons: 2006 and 2007. The randomized complete block design (RCBD) field experiment was designed with 5 chilling hours (CHs) periods (0, 360, 750, 1080, and 1440 CHs under 2 ± 1 °C), with four replicates each. Accumulative photo-thermal unit (PTU) was calculated for every treatment at different base temperatures for two stages: (i) from planting date to the flower opening (THA) and (ii) from planting date until the end of 2 months (THB). The results revealed that the plants treated with 1080 h of chilling produced flowers with about 55.12% and 61.97% earlier when compared with control (without chilling) in both the seasons, respectively. Stepwise multiple regression analysis showed that both CHs and the accumulative PTU THA13 (in the first season) and CH plus THA10 (in the second season) have significant effect on days until flower opening, in which the majority effect was related to the chilling period. The effect of chilling period and accumulative PTU at 18 °C (THB18) had s significant influence (p < 0.05) on the number of early flower per plant, with about r2 = 0.250 and r2 = 0.536 in both the seasons, respectively, and r2 = 0.531 and r2 =0.740 for the total effect of both CH and THB18, respectively. However, the exposure of plants to the long period of chilling (1080 and 1440 h) led the plants to produce runners and break up the flowering stage after 9 and 11 weeks in both the seasons, respectively. Meanwhile, plants that received 360-h chilling produced significantly highest (p < 0.05) total number of flowers (24.83 per plant), with about 71.2% higher than that produced by control plants. Moreover, in the second season, plants treated with 750-h chilling produced the significantly higher total number of flowers per plant, with about 50.3% higher than that of the control. Meanwhile, the 360-h and 750-h chilling periods have similar effect on the number of flowers per plant in the second season. The result showed that the starch level in the crown significantly positively correlated with the days to flower opening (r2 = 0.415, p = 0.05) and negatively correlated with the number of early flower (r2 = 0.587, p = 0.01). The data from this study might be used for the management of strawberry production.

Head size contributes substantially to seed yield of sunflower because it influences both number of seeds per head, and seed size. The aim of this field study was to determine the variability of head diameter in sunflower hybrids depending on planting date across three cropping seasons. Three hybrids (Miro, Rimi, Pobednik) were sown at four planting dates (PD1 - 20th of March, PD2 - 10th of April, PD3 - 30th of April, PD4 - 20th of May). Head diameter was analysed in the stage of flowering and physiological maturity. The trial was arranged as Randomized Complete Block Design (RCBD) with four replications. Analysis of variance (ANOVA) showed that the effect of year, hybrid, planting date and most interactions were highly significant for head diameter in the flowering stage. In the stage of physiological maturity head diameter varied significantly depending only on the planting date. Also, all interactions, except year ? hybrid (Y ? H), were highly significant. Planting date had significant influence on head diameter in the stage of flowering and physiological maturity in sunflower. With later sowing head diameter increased, so that significantly highest head diameter across planting dates was found in PD4 (11.8 cm in flowering stage, and 22.6 cm at the stage of physiological maturity). Study results may be helpful in the recommendation for optimal planting date in sunflower.

Abstract A field experiment was applied at the research station in Al-Najmi district, Al-Muthanna governorate during the agricultural season 2020-2021, to determine evaluating several cultivars of wheat by changing the date of their cultivation. The experiment was applied using the split plot using the Randomized complete Block Design(RCBD) with three replicates experiment method, where the planting dates were occupied (1/11, 15/11, 1/12 and 12/15) the main plots, while the cultivars (Baghdad, Furat, Rashid, and Wafia) occupied the secondary plots and with three replicates. The results showed that the planting date (1/12) was superior to the number of days up to 75% of flowering, the number of spikes. m−2, and the grain yield ton. ha−1, which amounted to 109 days, 409.9 spikes and 5.77 tons, respectively. While the planting date (15/11) exceeded in both characteristics the leaf area and the number of grains in the spike, as it reached 46.18 cm and 49.78 grains. As for the cultivaries, the Baghdad cultivar surpassed in the characteristics of the area of the flag leaf, the number of fertile spikes, the number of grains per spike, and the grain yield, which reached 44.70 cm, 395.7 spikes.m−2, 48.38 grains, spike−1 and 6.16 tons.ha−1, respectively.

Potato stolon and tuber number are the most important determinants of yield and these traits are associated with planting time and genotype. This study was conducted to evaluate plant growth, tuber yield contributing traits and tuber yield of potato genotypes in two planting dates. The experiment was done in randomized complete block design with three replications. Results showed that plant growth and traits that contribute to tuber yield of potato were significantly influenced by planting dates and genotypes. Stolon and tuber number as well as tuber weight were periodically investigated. It was observed that the performance of those traits were always higher in 23rd November planting. Different genotypes performed differently on all the studied parameters. Among the genotypes tested, G1 (AC 10069) produced the highest number of stolons, tubers, tuber weight, length and yield of tuber as compared to the check variety. It was observed that 23rd November planted G1 (AC 10069) gave the highest tuber yield (17.79 t.ha-1) which was statistically similar with G3 (AC 10110) (17.00 t.ha-1) when compared to the check variety. It can be concluded that planting time as well as genotype are the critical factors that determine potato yield.
