Abstract The experiment was carried out in the greenhouse of the Agricultural Research and Experiment Station - Kirkuk University - College of Agriculture for the agricultural season 2020-2021. The experiment was started on 20-11-2020. Carnations were taken from the mothers before the start of the experiment and planted in culture dishes to complete the rooting process. Carnations were planted on terraces with a length of (20 m) and width (75 cm), and the distance between one line and another (30 cm) and between one plant another (30 cm) as well. Artificial lighting (white LED light factor, 40 watts) was used for four hours in addition to the natural light which started half hour before sunset. The intensity of lighting was measured by a light meter (Lux 6612). As for the mulching factor, the industrial mulching was used with white polyethylene and the natural mulching with shredded yellow corn residue with a thickness of 2.5 cm, in addition to the control treatment. The experiment was carried out in a split-plot system in a randomized complete block design (RCBD) and the treatment of illumination was placed in the main plots, while mulching was placed in the secondary plots, and the results were tested according to Duncan’s multiple range test at a probability level of 5%. The following characteristics were studied: plant height (cm), plant total chlorophyll content (CCI), number of days required for flowering (day), number of flower/m2, and flower stem length (cm). The results showed the superiority of lighting and mulching treatment in all vegetative and flowering traits under study.

Agrochemical use in horticultural cultivations generates negative effects, thus the need for searching to decrease or eliminate its use by means of other less toxic techniques. Agricultural homeopathy represents an alternative for ecological agriculture, impacting positively in cultivation development. The effect of four homeopathic medicines for human use were assessed in two centesimal dynamizations (7CH and 13CH) [(Silicea Terra (SiT), Natrum muriaticum (NaM), Zincum phosphoricum (ZiP) and Phosphoricum acidum (PhA)], and a control treatment (distilled water) on tomato plant germination, emergence, and initial development. The treatments were established under a randomized complete block design with three repiclates. Germination and emergence rate and percentage and morphometric variables (plant height, radicle length, dry and wet weight) were assessed, including the variables in stem diameter and wet and dry leaf weight, number of branches, leaves, and buds in the vegetative development stage. Signif icant differences were observed in all the morphometric variables assessed in function of the different development stages, homeopathic medicines, and their different dynamizations. During germination, greater growth in stem length was observed with ZiP-7CH (5.5 ± 0.98 cm) compared to the control group (4.3 ± 1.10 cm). During the emergence stage, the treatments SiT-7CH (6.6 ± 1.11 cm) and ZiP-7CH (5.9 ± 1.41 cm) increased stem length signif icantly whereas with PhA-7CH, the best effects were obtained in the variables assessed during the vegetative development stage, LT (94 ± 8.31 cm), leaf number (No hojas) (131 ± 27.71), fresh stem biomass (BFT) (17.20 ± 2.45 g), wet leaf biomass (BFH) (30 ± 7.72 g), dry leaf biomass (BSH) (2 ± 0.61 g), fresh root biomass (BFR) (10 ± 6.26 g), dry root biomass (BSR) (1 ± 0.43 g), and number of flower buds (No H) (6 ± 7.10). The homeopathic medicines applied impacted positively during the initial and vegetative development stages of tomato under controlled conditions. This research study represents and advance in the sustainable management of tomato cultivation.

Carnation (Dianthus caryophyllus L.) is one of the most commercially important cut flowers of the world. It can be used for cut flowers, bedding, edging, boarders, pots and rock garden. Four Spanish carnation varieties were tested with three levels of boron under ultra-violet stabilized polytunnels from August 2017 to April 2018 at Godawari, Nepal. The objective of the research was to evaluate vegetative, floral, and vase life parameters in relations to growth, yield and quality of carnation. The research was conducted in a randomized complete block design with 3 replications. The variety Baltico had the maximum leaf length (19.3 cm), numbers of lateral branches (10.5), internodal length (5.1 cm), flower diameter (8.6 cm), and vase life (24.0 days). The numbers of nodes (5) and flower weight (25.4 g) were highest in the variety Vinco with the lowest cracked area on the stem (0.2 cm2/ crack). The numbers of stem cracks per plant significantly (p ≤0.01) reduced with an increasing level of boron though non-significant relation was observed on 60 ppm and 120 ppm. Variety Baltico was found as a better variety compared to the Vinco, Cervantes and Master varieties according to the vegetative, floral, yield and vase life parameters. Among the levels of boron tested, 60 ppm was found as the optimum dose. Thus, variety Baltico and 60 ppm boron is suggested to be used at the climatic condition of Lalitpur.

Carnation is an important cut flower in Nepal. Several cultivars imported from abroad are being adopted for their commercial production. However, the performance of these cultivars in  the specific agro-climate has not yet determined. Thus, study aimed to evaluate the performance  of common cultivars, including mineral nutrition and IAA hormone on the plant growth and flowering. The study was carried out in Horticulture Research Division, Khumaltar, Nepal during 2012 and 2013. Four cultivars: King Lion, Delson, Eskimo and White Liberty including nitrogen and foliar application of IAA were evaluated for plant growth and floral characteristics. The experiment was held in randomized complete block design (RCBD) with four replications.Based on the results, cultivar King Lion had significantly highest plant height (20.66 cm),  while cultivar Eskimo had the highest flower stem length (53.59 cm) and stem diameter (5.63 cm) followed by Delson (51.66 cm). The lower flower stems lengths of cultivars: White Liberty (42.48 cm) and King Lion (43.87 cm) were at par. The effect of mineral nutrition and hormone on plant height, flower stem length and flower head diameter was non-significant, however, IAA 25 ppm foliar spray was found superior over N 40 g/m2 and IAA 50 ppm applications. Thus, Eskimo is recommended as the excellent cultivar for its bigger flower stem, straightness and attractive flower looking, while cultivars; Delson and White Liberty as promising for higher flower yield. Similarly, soil application of nitrogen @ 40 g/m2 and foliar spray of auxin @ 25 ppm are recommended for higher flower yield.

The experiment was conducted during rabi season 2018-19 and 2019-20 at Regional Agricultural Research Station Jashore to develop a bio-rational based sustainable management approach to control flea beetle of cabbage. The experiment was laid out in a randomized complete block design with three dispersed replications. Cabbage seedlings were transplanted on 10th November 2018 and 11th November 2019, respectively. The experiment was five different treatments with one control treatment viz. T1 = White color sticky trap + Matrin (Biotrine 0.5% @ 1ml/L of water) @ 1ml/L of water, T2 = Spraying of Antario @1.0 ml/L of water, T3 = Alternate spraying of fizimite and Antario @ 1ml/L of water, T4 = Spraying of Bio-clean (D-Lemonine 5% SL) + application of recharge @ 3gm/L of water, T5 = Spraying with Nitro 505EC (Chlorpyriphos + Cypermethrin) @ 2.0 ml/L of water and T6 = Untreated control. The whole plant was thoroughly covered by spray emulsion. The lowest number of flea beetle (14.59 in 2018-19 and 10.33 in 2019-20) was found in the treatment T5 (Spraying with Nitro 505EC (Chlorpyriphos + Cypermethrin) @ 2.0 ml/L of water) and highest (35.76 in 2018-19 and 42.53 in 2019-20) in control (T6) treatment. The lowest percent of head infestation of cabbage was also recorded in T5 treatment (14.03% in 2018-19 and 5.10% in 2019-20) and the highest in T6 treatment (27.61% in 2018-19 and 23.69% in 2019-20). The highest yield (33.40 t/ha in 2018-19 and 32.49 t/ha in 2019-20) was recorded from T5 treatment and the lowest (26.87 t/ha in 2018-19 and 24.78 t/ha in 2019-20) in control (T6) treatment in both the year. On an average, 16.55-20.33 flea beetle were captured in yellow sticky trap per week in both the year. The highest gross margin (438466 Tk.//ha in 2018-19 and 262366 Tk.//ha in 2019-20) was also observed in the T5 treatment in both the year and the lowest (342916 Tk.//ha in 2018-19 and 187666 Tk.//ha in 2019-20) in untreated control (T6) treatment. Finally, the results revealed that the treatment T5 was more profitable compared to other approaches as well as the highest crop yield with marginal benefit cost ratio.

The experiment was conducted for two consecutive rabi seasons of 2005-06 and 2006-07 at the Regional Agricultural Research Station (RARS), BARI, Jamalpur to find out an optimum dose of sulphur for yield maximization of garlic cv. Jamalpur local. There were six levels of sulphur viz., 0, 15, 30, 45, 60, and 75 kg/ha. A control treatment was in the experiment. The experiment was laid out in randomized complete block design with three replications. The fertilizer package N150P60K120Zn4 B1 kg/ha was applied to each plot as blanket dose.  Results revealed that most of the growth and yield parameters increased progressively with increasing rate of sulphur application. Bulb yield increased with successive increase in the level of sulphur up to 45 kg/ha and thereafter decreased. The highest bulb yield (7.05 t/ha in 2005-06 and 7.22 t/ha in 2006- 07) was achieved at 45 kg S/ha and the control treatment receiving no fertilizer had the lowest yield (3.21 t/ha in 2005-06 in and 3.26 t/ha in 2006-07). The yield benefit for 45 kg sulphur per hawas 34.2% in 2005-06 and 40.0% in 2006-07 over no sulphur. Sulphur at 45 kg/ha produced 54.5% and 54.9% higher yield over control treatment in both the years. The optimum and economic dose of sulphur for the yield of garlic were 44.0 and 43.6 kg/ha, respectively. DOI: http://dx.doi.org/10.3329/bjar.v36i4.11751 Bangladesh J. Agril.
