The experiment was conducted at established rose garden of Regional Agricultural Research Station, Bangladesh Agricultural Research Institute, Jashore during 2017-18 and 2018-19 winter season (November-April). The experiment was laid out in a RCBD design with three dispersed replications. Four treatment combination were as follows: T1 =IPM package-1: Mechanical control + Sticky trap (Blue and White) + weekly spray of Azadirechtin (Bio-neem plus 1EC) @ 1.0ml/L of water, T2 = IPM package-2: Mechanical control+ Sticky trap (Blue and White)+ spray of Thiamethoxam 20% (Virtako 40SC) @ 1.5 ml/L of water, T3 = IPM package-3: Mechanical control+ Sticky trap (Blue and White)+ weekly spray Chlorphenapyr (Intrepid 10EC) @ 1 ml/L of water and T4 = Farmers practice: weekly spray Imidacloprid (Imitaf 20SL) @ 0.5ml/L of water. For mechanical control hand picking was done and harmful insect also classified as the most direct and the quickest way to remove clearly visible pests. Two color stiky trap (white and blue) were set up in each line. The lowest number of rose thrips was found in IPM package 2 (6.36 in 2017-18 and 3.03 in 2018-19) and highest in farmer’s practices (14.36 in 2017-18 and 12.40 in 2018-19). The lowest percent flower infestation of rose was recorded in IPM package 2 (9.98 to 17%) and the highest in Farmers practice (19.72 to 32.66%). The highest yield (864000 no./ha in 2017-18 and 535932 no./ha) was recorded from IPM package 2 and the lowest in farmers practice (438750 no./ha in 2017-18 and 388857 no./ha). The results revealed the highest MBCR was observed in IPM package-2 (Mechanical control+ Sticky trap (Blue and White) + spray of Thiamethoxam 20% (Virtako 40SC) @ 1.5 ml/L of water.) treated plot (17.2 to 49.7) in both the year. Finally, it may be recommended that IPM package 2 is very much effective to control thrips of rose as well as high yield and more economic return. Progressive Agriculture 31 (2): 89-93, 2020

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.

This experiment was conducted at a closed poultry house , Poultry Research Station , office of Agricultural Research, Ministry of Agriculture, Baghdad, Iraq, for the period from 2/9 to 14/03/2016 for total rearing of 35 days. To diagnose and monitoring the Environmental factors such as temperature, humidity , density, and the carbon dioxide levels inside the house during winter season, and its impact on the productive performance of broiler chickens Rose 308 breed .The dimensions of the house was ,length 35 m x width 7.5 m x Height 2.5 m, by total space volume 3656.25 m3. The ventilation system in the house was (negative pressure type). The house is totally closed, small fans for (minimum ventilation) in the winter are functioned, and large fans for ventilation in the evaporative cooling operation were used in the summer. 1000 sexed birds were used in this experiment imported through commercial hatchery in Abu Ghraib. The house was divided into three thermal Zones in order to find out whether heterogeneity in environmental conditions is existed in the house and at bird level .as a result the impact on the homogeneity in the weights of marketed birds . The treatments have been distributed into 32 rearing cages by the following order: 8 cages with the density of 50 birds / cage, the remaining 24 cages were divided into the density of 25 birds / cage. The results showed that there were significant differences between the treatments in the rate of body weight ,body weight gain, feed intake and feed conversion efficiency among   densities and the three thermal zones due to the presence of cool air leaks into the house at the front ,End of the house, and its sides especially when fans are on , along with dead Air pockets that were identified in many places in the middle of the housed, yet this Zone was the one that had the best productive traits in comparison with the other two zones. The purpose of this experiment is to study environmental parameters homogeneity  inside the shed in addition to impact of CO2 levels and impact of birds density on productive traits.

The paper presents the results of the researches carried out at the Agricultural Research Station Oradea, Bihor County, between 1994 and 2002, regarding millet and wheat yields from a haplic luvosoil polluted under control with oil brought from the exploitation site at Suplacu de Barcău. Phytoremediation is a recent technology that is used to stabilize or remove wastes from soils, groundwater or other medium by using living plants. The experimental device was made out of micro parcels of 1 m², set up in a randomized manner, in a Latin square, polluted with a concentration of: 0, 1, 3, 5 and 10 % (0, 3, 9, 15, and 30 l/m²), oil in the ploughed layer, in four repetitions. The experience was than cultivated with in the first three years with millet (1993-1995), a plant that is considered to be resistant to pollution, and than until 2002 with spring wheat. The tendency of relative yields of polluted plots show that in the time of research period of ten years, the pollutant was phyto degraded, without any ameliorative measures. For the plot variants polluted with different concentration of crude oil, between the relative yields and time of research period was established second degree polynomial correlations, distinct and very significant statistically. The shape of the curves indicates the fact that after a minimum of relative yields, registered in the first or the second year of research period these increases continuously in time, until the finish of the experiment. The intensity of soil pollution, in the last year of research period, using the yield losses, in the plots with 1 % oil concentration is unpolluted, in the plots with 3 % oil concentration is weakly polluted, in the variant plots with 5 % oil concentration is moderate polluted and respectively in the plots with 10 % oil concentration is yet strong polluted. The time of phytodegradation, evaluated with help of equations, through the condition for relative yields to be 95 %, when the soil pollution characterization became unpolluted results that: on the 1 % variant the soil became unpolluted after 5,4 years, on the 3 % after 7,8 years, on the 5 % variant after 9,6 years, and on the 10 % variant the soil became unpolluted after 10,8 years.

In Southern India, drought stress is a major constraint to chickpea production and yield stability. Drought tolerant index (DTI) that provides a measure of drought based on yield loss under drought condition in comparison to normal condition was used for screening drought-tolerant genotypes. This study was conducted to determine drought tolerant genotypes with high yield in stress and non-stress conditions utilising physiological traits. Thirty chickpea genotypes were tested in a randomized complete block design with three replications under rain fed and irrigated conditions at Regional Agricultural Research Station, Nandyal, Andhra Pradesh, India during rabi, 2018-2019. The analysis of variance carried out for yield and drought tolerant traits revealed highly significant differences among the genotypes for all characters under rain fed as well as irrigated conditions. NBeG 776, NBeG 779, NBeG 868, ICCV 181606, MH 13 and MH 14 are drought tolerant. NBeG 776, NBeG 779 and NBeG 868 are suitable under both rain fed and irrigated conditions with significantly higher yields over their respective means. ICCV 181606, MH 13 and MH 14 are suitable exclusively for rain fed condition with significantly superior yields over the mean.

Sowing Depth

Abstract In South Asia, including Bangladesh, most farmers sow wheat under residual soil moisture after rice is harvested, but the upper layer of soil dries quickly after soil has been prepared for wheat sowing. Crop seeds that are sown either deeply or shallowly can result in failed emergence, low dry matter accumulation, and reduced grain yield. Therefore, appropriate sowing depth is crucial for seedling emergence and successful crop establishment. Considering this, a two-year field experiment was conducted at the research field of the Agricultural Research Station of the Bangladesh Agricultural Research Institute at Dinajpur during the dry, rabi (winter) season of 2013-14 and 2014-15, at four sowing depths, i.e., 2, 4, 6 and 8 cm, to identify the most appropriate sowing depth for higher grain yield. Wheat seeds sown at a depth of 4 cm resulted in significantly highest number of seedlings and seminal roots, tallest plants as well as largest roots and plant biomass followed by sowing at a depth of 6, or 2 cm. Depth of sowing also significantly affected the yield and yield-related attributes, all performing best at a depth of 4 cm. The highest number of spikes m-2, grain yield, straw yield and harvest index were observed when seeds were sown at depths of 4 or 6 cm, relative to 2 or 8 cm. Therefore, a sowing depth of 4 to 6 cm is recommended for wheat cultivation in South Asia, including Northern Bangladesh.

Effectiveness of integrated management approaches using blue sticky trap, pheromone trap, bio and synthetic insecticides were evaluated against major insects, like flower thrips and pod borers of mungbean at Regional Agricultural Research Station, Rahmatpur, Barishal and Pulses Research Centre, Ishurdi, Pabna, Bangladesh, respectively, during two consecutive years of 2018 and 2019. All of the management packages significantly reduced flower infestation, thrips population and pod borer infestation in mungbean. The highest percentage of reduction of flower infestation, thrips population and pod borer infestation was found in IPM package-3: installing blue sticky trap + two spraying of chlorfenapyr (Intrepid 10 EC) @ 1 ml/l + third spraying with (chlorantraniliprole + thiamethoxam), i.e. Virtako 40 WG) @ 0.15 g/l, followed by IPM package-1, IPM package-2 and recommended practice (spraying imidacloprid, i.e. Imitaf 20 SL @ 0.5 ml/l). The highest yield was also recorded from IPM package-3, which was statistically similar to IPM package-1, followed by IPM package-2 and recommended practice. Although the IPM package-3 provided the highest yield and return, followed by IPM package-1, but recommended practice (farmer’s practice) gave the highest benefit because of higher cost of IPM components brought down the profit margin of IPM packages. The components of IPM package-1, i.e. biopesticides, are ecologically safer than that of IPM package-3 (synthetic chemical insecticides). So, considering environment friendliness, the IPM package-1: installation of blue sticky trap and pheromone trap + two spraying of azadiractin (Biomeem plus 1EC) @ 1 ml/l + third spraying with spinosad (Success 2.5 EC) @ 1.2 ml/l would be the best package for controlling flower thrips and pod borers of mungbean with higher yield in the insects prone areas, without harming the ecosystem.

Abstract The study was conducted during the winter season 2021 at the Agricultural Research Station of the College of Agriculture, University of Basra. In order to study the effect of soil Mulching and the addition of cobalt on the growth and green yield of green bean plants grown under greenhouses conditions, the experiment included 12 factorial treatments, which consist of the four types of plastic coverings (black, white, transparent and without Mulching ) and three concentrations of cobalt as a cobalt sulfate (zero, 5 and 10) ml g L-1, as the Mulching with white plastic achieved the best results in most of study parameters. The addition of cobalt at concentrations 5 and 10 ml.g L-1 recorded the best values in plant height, number of leaves, leaf area and number of root nodes, and white and black caps also outperformed in pod weight, yield of plant green pods, total yield of green pods and pod length. The white cover achieved the best value in the percentage of protein of seeds, while the transparent cover was recorded best value in the percentage of dry matter in the seeds. Foliar cobalt application of concentrations 5 and 10 mlg L-1 recorded best value in pod weight and per the yield of pods. Plant -1 yield., pod diameter and the percent of dry matter in the seeds, and the concentration of 5 mlg L-1 achieved the highest value in the number of pods and protein content in the seeds.

Abstract The long-term experiments carried out at the Agricultural Research Station of Podu-Iloaiei, Iaşi County, Romania, tried to establish some fertilization systems for getting efficient yield increases, which maintain or increase the content of organic carbon from soil. These trials were set up on a 16% slope field, with a cambic Chernozem soil, which has a clayey-loam texture, a neuter to weakly acid response and a mean supply in nutrients. Analyzes performed on soil profiles after 44 years, on land with a slope of 16% and slope length of 310 m, shows that the entire length of slope soil fertility were very different, being influenced by processes of erosion and silting. Soil organic carbon, the depth of 0-20 cm, was between 45.94 t / ha, the foot slope and 27.45 t / ha in the mid-slope area with strong erosion. From the results obtained on erosion in different crop rotations, we have found out that in 16% slope fields from the Moldavian Plateau, soil losses by erosion were diminished below the allowable limit of 3-4 t/ha/year only in case of 4 year-crop rotations with two reserve fields, cultivated with legumes and perennial grasses, which protect soil. Annual soil losses by erosion, registered during the last 30 years, in the Moldavian Plateau, were between 0.246 t/ha in perennial grasses, on the second year of vegetation, and 8.976 t/ha in sunflower. The fertilization of wheat and maize crops at the rate of N80P80 + 60 t/ha manure has determined the increase with 5.5 t/ha (7.8%) in the content of organic carbon from soil, as compared to the rate of N140P100.

Irrigation Time

Chickpea is one of the important winter legumes in Nepal. It is grown after rice or maize either as sole or mixed crop. In Nepal, chickpea is mostly grown as rainfed crop on residual soil moisture or sometimes under irrigation. Lack of irrigation results drought and heat stress which affects crop growth and development. Irrigation at proper time is one of the most important factors for achieving higher crop yield.  The experiment regarding use of supplementary irrigation time on chickpea was carried out at Regional Agricultural Research Station, Khajura, Banke, Nepal during the winter season of the year 2011 and 2012. The experiment was laid out in Randomized Complete Block Design with three replications. Seven different time intervals of irrigation was applied in the experiment for both years. Treatments differed significantly in terms of grain yield but showed non -significant difference in days to flowering and maturity over the years. The combined analysis of the experiments showed that the highest grain yield (2318 kg/ha) was produced when irrigation was supplied at vegetative stage followed by irrigation supplied at flowering stage (2298 kg/ha) and pod fill stage (2104 kg/ha) respectively.Int J Appl Sci Biotechnol, Vol 3(3): 431-433
