Planting dates for a crop is a non-monetary input but plays a significant role in increasing the yield crop. Therefore, identifying genotype-specific planting dates is essential for obtaining the economic yield of tropical sugar beet. From this perspective, a field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University in  Bangladesh, from November 2015 to April 2016. Five sugar beet genotypes: Shubhra, Cauvery, EB-0616, EB-0626, and EB-0809 planted on four dates: 10, 20, 30 November, and 10 December. Treatments were laid out in a split-plot design replicated three times. Data revealed that planting on 10 November date, genotype EB-0809 produced the highest tuber yield, which was significantly superior to any other genotype combined with other planting dates. It was found that every ten days delay of planting from 10 November to 30 December reduced the tuber yield by 30, 43, and 55%, respectively. Results confirmed that planting the EB-0809 genotype on 10 November is ideal to obtain the highest tuber yield of tropical sugar beet in Bangladesh.

A field experiment was conducted on varietal response of white yam to moisture regime in Abeokuta. The experiment comprised three varieties of yam (Efuru, Ise-osi and Oniyere), three mulching options (grass, polythene and unmulched), and two planting dates (early and late). Treatments were replicated three times using RCBD lay-out. Model for selecting planting date involved relating potential evapotranspiration (PE) to precipitation (P) in the form of 0.1PE<P < 0.5PE, partitioned for attaining optimal planting date into early {T1= Σ(P-0.1PE) ≤ 0} and late {T2 = Σ(P-0.5PE) ≤ 0}, respectively. For humid period defined by P> PE, the physiological parameters and moisture agro-climatic indices measured during phenological stages of yam grown were analyzed with respect to treatments. Result showed that T1 defined as Σ(P-0.1PE) ≤ 10 mm appeared as the best model that significantly (P < 0.05) influenced emergence rate, phenological growth and tuber yield. All yam varieties evaluated were suitable for planting with respect to yield. Efuru and Ise-osi synchronized perfectly with Actual Water Availability and produced good vegetative growth with LAI of 1.08 and 0.91 leading to higher tuber yield of 12 and 11.64 tonnes ha-1, respectively. Grass mulch had tuber yield, 4-6 tonnes ha-1greater than the polythene and unmulched plots in all varieties. Mulching significantly (P< 0.05) increased tuber yield, 6-8 tonnes ha-1than the unmulched. Conclusively, early planting with grass mulch increased tuber yield.

Field experiments were carried out at research farm of Department of Agricultural Meteorology, CCSHAU, Hisar during Rabi seasons of 2016-17 to quantify crop weather relationship and the effect of different planting dates on growth and yield of potato cultivars in a sub-tropical environment at Hisar. The experimental field was adjacent to Agro-meteorological observatory at 290 10' N latitude, 750 46' E longitude and altitude of 215.2 m. The main plots treatments consisted four date of sowing viz. D1- 8th Oct., D2-22th Oct., D3- 5th Nov. and D4- 23rd Nov. The sub-plots treatment consisted of three varieties (V1- Kufri Bahar, V2- Kufri Pushkar and V3- Kufri Surya). The forty eight treatment combinations were tested in split plot design with four replications. The results revealed that various growth and yield observations were recorded higher in second sown crop (22th Oct.) as followed by other planting dates. The maximum tuber yield were produced in D2 (20810.45 kg/ha) and it was least in D4 (14525.46 kg/ha). Among the varieties, Kufri Pushkar recorded highest tuber yield (21478.06 kg/ha) followed by Kufri Bahar (17432.26 kg/ha) and Kufri Surya (15378.11 kg/ha). In crop weather relationship, Tuber yield and plant height were significantly positively correlated with rainfall (0.80 and 0.92) and rainy days (0.50 and 0.53). Evening relative humidity was also positively correlated with LAI (0.59) and tuber yield (0.78) of potato. Vegetables production is considered to be particularly important in satisfying world food demand. Specific research therefore is needed in order to evaluate the effects of environmental factors that crop encounters during its growth period and its production.

The NDVI was used to discriminate tobacco variety, assess fertilizer levels, and determine the impact of planting date on separating crops. A split plot design with four planting dates, September, October, November, and December, as main plots, variety as subplot, and fertilizer treatments as sub-subplots was used. Radiometric measurements were taken from 5 m × 5 m sampling plots, using a multispectral radiometer. The September, October, and November crops had significant variety x fertilizer treatment differences (F<0.05) from the age of 10 weeks. T 66 and KRK26 varieties had similar (F>0.05) NDVI values and these were greater (F<0.5) than those for K E1. The 100% and the 150% fertilizer treatments were similar (F>0.05) and both were greater (F<0.05) than the 50% fertilizer treatments. All of the fertilizer and variety treatments at the December planting dates had similar reflectance characteristics (P>0.05), which were lower (P<0.05) than the September and October planting dates. The results showed that planting dates, varieties, and fertilizer levels could be distinguished using spectral data. Weeks 10-11 and 15 after the start of the experiment were optimal for separating the planting date effect.

In our small block experiment in randomised blocks, we examined the effect of 6 foliar treatments at 3 different nutrition levels in 2002 on meadow chernozem soil.The experiment consisted of 3 blocks, which corresponded to 3 different nutrition levels. The first block was the control, the fertilization rate of the second block was 20 kg ha-1 N, 40 kg ha-1 P2O5, 120 kg ha-1 K2O, on the third block 40 kg ha-1 N, 80 kg ha-1 P2O5, 240 kg ha-1 K2O were applied. We applied magnesium and strobilurin active ingredient (Juwel, BAS 51200), in different combination and with different application dates.We found that the foliar treatments with bioactive fungicides significantly influenced the yield and some quality parameters in this field experiment.

Abstract A field experiment was carried out in the experimental field of the Department of Field Crops, College of Agriculture/University of Al-Muthanna during the spring season 2021 to determine the effect of planting dates on some growth characteristics of sorghum. The experiment was applied by arranging the split panels according to the RCBD design and with three replications. The main panels included three planting dates (4/15 ’ 4\5 ’ 3/25) while the secondary panels included gibberellin treatments (0, 100ppm) and the results were as follows: The planting date exceeded the first date 3/25 in the number of days to 75% flowering (97.5 days), the height of the plant (143.74 cm) and the diameter of the stem(2.34 cm) and the number of leaves per plant (8.73 leaves). 75% flowering, giving(92.33) days, plant height (136.55 cm), stem diameter (2.04 cm) and number of leaves (8.10 leaves).

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.
