Field experiments were conducted in the Grey Terrace Soil (Aeric Albaquept) under AEZ-28 at the Bangladesh Agricultural Research Institute (BARI) farm, Gazipur during summer seasons of 2010 and 2011 to determine the optimum rate of boron and molybdenum combination for maximizing the yield of summer country bean (var. BARI Sheem-3). Four levels each of B (0, 1, 2 and 3 kg ha-1 ) and Mo (0, 0.5, 1.0 and 1.5 kg ha-1 ) were used as treatment variables. The results indicated that application of B and Mo fertilizer combination exerted significant influence on the number of pods plant-1 , individual pod weight and pod yield ha-1 in both the years. The highest pod yield (9.58 t ha-1 in 2010 and 9.42 t ha-1 in 2011) was produced by the combination of 2 kg B and 1.5 kg Mo ha-1 and it was statistically identical with 2 kg B and 1.0 kg Mo ha-1 combination. Addition of B beyond 2 kg ha-1 along with higher doses of Mo created a detrimental effect to reduce yield irrespective of years. The results revealed that application of 2 kg B and 1 kg Mo ha-1 combination with a blanket dose of 50 kg N, 40 kg P, 60 kg K and 20 kg S ha-1 plus cowdung 5 t ha-1 might be optimum for summer country bean cultivation in Grey Terrace Soil of Gazipur.Bangladesh J.

SUMMARYSix intercropping systems and four levels of nitrogen were compared at the Indian Agricultural Research Institute, New Delhi, in the summer rainy seasons (July-October) of 1978 and 1979. The maximum increase in sorghum yield was obtained when it was associated with fodder cowpea, followed by association with grain cowpea and greengram. The application of 40, 80 and 120 kg N ha−1 increased sorghum yield by 8.6, 16.1 and 18.2% in 1978 and by 2.9, 8.1 and 14.1% in 1979, respectively, compared with unfertilized sorghum. The nitrogen uptake by sorghum, and by the total system, was greater in sorghum-legume intercropping systems than in sole sorghum. Nitrogen application also increased the nitrogen uptake by sorghum and by the whole system.

Corn Hybrid

Limited information exists on sweet corn tolerance to postemergence (POST) applications of clopyralid under Ontario growing conditions. Eight sweet corn hybrids were evaluated for tolerance to clopyralid in three field experiments conducted in 2001 and 2002 in Ontario. Clopyralid was applied POST at 200 and 400 g ai/ha, the proposed and twice the proposed registered rate for use in sweet corn in Ontario. Sweet corn response to clopyralid did not vary among the hybrids tested. In 2001, visual injury among hybrids 7 d after treatment (DAT) with clopyralid at 400 g/ha was less than 3%. Subsequent visual injury evaluations at 14 and 28 DAT showed no differences among sweet corn hybrids at either rate of clopyralid evaluated. The application of clopyralid at 200 and 400 g/ ha had no detrimental effect on plant height or marketable yield of any of the eight sweet corn hybrids. On the basis of visual injury, height, and marketable yield response ‘Calico Belle’, ‘CNS 710’, ‘DelMonte 2038’, ‘GG 222’, ‘GG 246’, ‘GH 2684’, ‘Reveille’, and ‘Rival’ are all tolerant to the POST application of clopyralid.

Field experiments under zero-till rainfed ecosystem were conducted during 2010-11 and 2011-12 at Indian Agricultural Research Institutive New Delhi for identifying the agronomic performance, weed dynamics, nutrient uptake and profitability of clusterbean based cropping systems (clusterbean-wheat, clusterbean-mustard and clusterbean-chickpea) as influenced by three residue management practices (no residue, crop residues and Leucaena twigs) applied to both summer and winter seasonal crops. Randomized Complete Block Design with four replications were used to conduct the trials. Significantly higher green-pod yield of clusterbean (10.08 t ha-1 and 6.70 t ha-1) was recorded with the application of Leucaena twigs, followed by crop residue mulching and the least with no-residue application in 2010 and 2011, respectively. Wheat and chickpea as preceding crops produced significantly higher clusterbean green-pod yield (6.54 t ha-1 and 6.43 t ha-1) than mustard (5.18 t ha-1). The yield attributes viz. pod-clusters and weight of pods per plant showed significant variation. Significantly higher dry matter yield (299.9 g m-2) of Cyperus iria was recorded with mustard residues followed by chickpea (253.1 g m-2) and wheat (194.0 g m-2) residues. The nutrient uptake showed the same trend as that of dry pod and stalks yields and resulted significant influence due to residue management and preceding crops. Economic analysis exhibited the highest returns and net returns per Rupee invested under wheat with Leucaena twigs followed by chickpea with Leucaena twigs. Clusterbean after wheat and chickpea with Leucaena twigs was high yielding and profitable for rainfed areas under zero-till semi-arid condition.

SUMMARYTreatments which lowered the rate of ammonia volatilization from surface-applied cattle slurry were evaluated in three field experiments during 1989/90 at the Agricultural Research Institute of Northern Ireland. The relative effects of separation, dilution with water before application and washing with a water spray after application, on ammonia volatilization rates were compared over 4 days using ventilated enclosures. As the loss rate of ammonia during the first 4 days after application was highly correlated with the loss rate over the first 4 hours after application, the loss rate in the first 4 hours was used as a rapid method to assess the efficacy of various combinations of separation, dilution and acidification. Ammonia volatilization loss rates from treatment combinations were compared to the loss rate from whole slurry.A 50% decrease in ammonia volatilization was achieved by separation through a 0·4 mm mesh, separation through a 10·0 mm mesh plus dilution with 86% by volume of water, or separation through a 2·0 mm mesh plus washing with 53% by volume of water.A 75% decrease in ammonia volatilization was achieved by acidification to pH 6·5, or combinations of separation and dilution, namely separation through a 0·4 mm mesh plus 50% dilution or separation through a 5·0 mm mesh plus 100% dilution.A 90% decrease in ammonia volatilization was achieved by acidification to pH 6·0, dilution by 50% plus acidification to pH 6·5, or separation through a 0·4 mm mesh plus acidification to pH 6·5.The effects of separation and acidification on ammonia volatilization were cumulative. There was a highly significant inverse linear relationship between ammonia volatilization rate and volume of nitric acid used. Adding 10 M nitric acid at 1·4% by volume lowered volatilization by 75% of that from whole slurry and increased the nitrogen content of the slurry by 2 g N/l, making it a more balanced NPK fertilizer for cut swards. Because the variable value of cattle slurry is due to loss of nitrogen as ammonia and smothering of the sward with slurry solids, a combination of separation or dilution to lower sward contamination and acidification with nitric acid to lower volatilization may be the best practical option for improving cattle slurry as a fertilizer for cut grass.

Field experiments with French bean comprising two varieties (BARI bush bean-1 and BARI bush bean-2), three plant densities (500 x 103, 333 x 103, and 250 x 103 plants/ha as maintained by 20 x 10, 30 x 10, and 40 x 10 cm spacings, respectively) and three levels of N (0, 60, and 120 kg/ha) were conducted at the Agricultural Research Station, Raikhali in the district of Rangamati during the winter (rabi) seasons of 2004-05 and 2005-06. BARI bush bean-1 outyielded BARI bush bean-2. The lowest plant density (250 x 10 plants/ha) recorded significantly higher values of growth and yield attributes, except plant height which was the maximum with the highest plant density of 500 x 103 plants/ha. The highest plant density of (500 x 103 plants/ha) resulted in the highest pod yield in comparison with the lower and medium plant densities. Application of 120 kg N/ha coupled with the highest plant density (500 x l03 plants/ha) gave the maximum pod yield of 34.3 t/ha and 30.2 t/ha in BARI bush bean-I and BARI bush bean-2, respectively.

Field experiments were carried out at the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during 2000-2002 to evaluate the effect of N and P applicaiton on the root growth, leaf photosynthesis and yield of groundnut (var. Basantibadam). Four levels of N (0, 20, 40 and 60 kg N/ha) and four levels of P (0, 13, 26 and 39 kg P/ha) were the treatment variables. The trial was set up in a randomized complete block design under factorial arrangement with three replications. Application of N and P fertilizer exerted significant effects on root development, photosynthesis, yield contributing characters and pod yield of the crop. Plant receiving 60 kg N and 39 kg P/ha had larger root system, greater photosynthetic rate and better yield contributing characters that resulted in the maximum pod yield which, however, was not significantly different from N60P26 treatment. Hence, it is recommended that higher yield of Basantibadam can be obtained from N60P26 kg/ha in salna silty clay loam soil of Madhupur tract (AEZ 28) of Bangladesh.DOI: http://dx.doi.org/10.3329/bjar.v32i3.538Bangladesh J.

Soybeans (Glycine max L. Merril) is the world’s most important seed legume and she is considered a basic food with a high nutritional value. The aim of this study is to evaluate the influence of two types of chemical complex fertilizers (NPK 27:13.5:0 and NPK 16:16:16) with four levels of fertilization (unfertilized, 150 kg/ha, 200 kg/ha and 250 kg/ha) on the main soybean growing stages in 2019. Field experiments were conducted in the soil and climate conditions of the Agricultural Research and Development Station from Turda. The vegetation stages of the studied soybean genotypes were influenced by: atypical climatic conditions of this year and also the type of fertilizer and the fertilization dose. By analyzing the experimental data, it was noted that one genotype had longer growing season (Raluca TD variety: 135-140 days), and three genotypes had shortest growing season (Perla variety: 122-125 days; Carla TD variety: 121-123 days; T-295 line: 121-123 days).

In a field experiment, conducted during 2018-19 and 2019-20 at the Research Farm, Indian Agricultural Research Institute, New Delhi, factorial combinations of two levels of FYM (0, 10 Mg ha−1) applied to maize; four levels of nitrogen (0, 60, 120, 180 kg N ha-1) and three levels of phosphorus (0, 30, 60 kg P2O5 ha−1) applied to both maize and wheat and subsequent residual effects on green gram were compared. The RGR was at peak in maize at 29oC and in wheat at 12-13 oC. Integral of LAD and incidental solar radiation has significantly improved CGR. The LAD and CGR also shown significant relationship with grain/ seed yield in all three crops. Slightly higher NAR in combination with LAD and SRD can significantly contribute to overall performance of crops. Results indicated that variation in yield across years due to weather fluctuations, irrespective of treatments, was about 16.7 per cent in maize (kharif), 7.93 per cent in wheat (rabi) and 16.8 per cent in green gram (summer).
