A field experiment was carried out during the winter season 2014/2015 in one of the fields of Abi Gharq district, located 10 km west of the Babylon governorate. The randomized complete block design was used under split-plots arrangement with three replications. The main plots were included levels of nitrogen fertilizer (without fertilizer, 50, 100, 150 N, 200, 250 kg). while the sub-plots were included (without a mower, a mower after 45 days, a mower after 65 days, a mower after 85 days) after planting, The data were taken and analyzed according to the used design and the averages were tested according to the LSD test, and the results were summarized as follows: The date of mowing C1 (mower after 45 days of planting) was significantly higher by giving the highest average for the degree of fallowness and the index of harvest, and the percentage of nitrogen in the green fodder was 3.647, 37.63% and 1.837%, respectively. Treatment C0 (without mower) outperformed significantly by giving it the highest average of biological yield, grain yield and nitrogen percentage in grains, as it gave 15,114 tons. H-1 and 5.73 tons. H-1 and 1.242%, respectively The fertilizer level N5 (250 kg N. H-1) gave the highest average of the degree of lying, biological yield, grain yield, nitrogen percentage in green fodder and nitrogen content in grains, as it gave 3.854% and 7.571 tons. H-1 and 6.20 tons. % And 1.397%, respectively, We conclude from the results of the study that lack of without cutting to a significant increase in the degree of resting, biological yield and grain yield, and we conclude that the high levels of nitrogen led to a significant increase in the degree of lying, biological yield, grain yield, and the proportion of nitrogen in green fodder and grains

Nepalese yellow maize inbred lines were characterized for general combining ability (GCA) and specific combining ability (SCA) of their crosses and parents were identified having high combining ability for determining the heterotic effects on yield and other quantitative traits of hybrids. A line x tester mating design was used for making the crosses in the winter season of 2008 and the hybrids along with their parents and four checks were evaluated in Randomized Complete Block Design (RCBD) with three replications in the spring season of 2009 at the experimental farm of the National Maize Research Program, Chitwan. Significant variations were found among the treatments for grain yield and other traits which indicated presence of high magnitude of genetic variations among tested inbred lines. The cross between RML-32 and RML-17 produced the highest grain yield (15870 kg/ha) among the crosses. Hybrids such as RL-194 x RL-84 (10770 kg/ha), RML-21 x RML-17 (9270 kg/ha), RL-180 x RML-17 (9270 kg/ha) and L-1 x RL-84 (8785 kg/ha) were found superior grain yielder. Thirty-nine hybrids showed positive mid-parent heterosis for grain yield among 40 crosses. The highest positive mid-parent heterosis for grain yield was found 880% in cross between RML-32 and RML-17, followed by RL-98X RML-17 (507%), RL-103 x RML-17 (403%), PUTU-18 x RML- 17 (351%) and RL-180 x RL 84 (316%).

To evaluate some agronomic properties and forage characteristics in the intercropping of barley (Hordeum vulgare L.) and vetch (Vicia ervilia L.), an experiment was conducted during 2014-2016 cropping seasons. A randomized complete block design with four replications was used. Intercropping patterns included 80% barley+ 20% vetch, 60% barley+ 40% vetch, 40% barley + 60% vetch and 20% barley + 80% vetch along with the sole culture of both crops (100% barley and100% vetch). The result showed that the highest value of plant height, grain number, thousand-grain weight, biological yield, grain yield and harvest in barley was observed from 80% barley + 20% vetch intercropping ratio, however, for vetch, it was detected from 100% vetch. Furthermore, the highest land equivalent ratio was obtained from 80% barley+ 20% vetch. Based on the results, the highest crude protein content and dry matter digestibility were observed in sole cropped vetch, whereas the highest neutral detergent fiber and acid detergent fiber were recorded in sole cropped barley. These results suggested that intercropped barley and vetch as 80% barley + 20% vetch ameliorated the grain yield and yield components, and forage quality compared to other intercropping ratios.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from July to December 2004 to evaluate the effect of hill spacing on the performance of BRRI dhan40 and BRRI dhan41 as Transplant aman crop. The experiment consisted of five hill spacings viz., 5cm. 10cm, 15 cm, and 25 cm where row to row spacing of 25 cm was kept constant for all treatments. The experiment was laid out in randomized complete block design with four replications. The 25 cm x 5 cm hill spacing produced the tallest plant, highest total number of tillers/hill, bearing tillers/hill lowest number of non-hearing tillers/hill, grain yield and harvest index, while 25 cm x 5 cm hill spacing produced the highest number of sterile spikelets/panicle, straw yield and biological yield. BRRI dhan41 produced higher grain yield (4.7 t/ha) which was the contribution of higher number of grains/panicle and heavier grain weight. Lower yield (4.51 t/ha) was recorded in BRRI dhan40.Key Words: Varietal performance; T. aman rice; hill density.DOI: 10.3329/bjar.v34i1.5750Bangladesh J. Agril. Res. 34(1) : 33-39, March 2009

An investigation was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University to inspect the effect of vermicompost based nitrogen management and plant spacing on the yield performance of short duration transplant Aus rice (cv. Parija). The study comprised three spacing viz. 20 cm × 20 cm, 20 cm × 15 cm and 20 cm × 10 cm, and five nitrogen management viz. no nitrogen, 75 kg N ha-1, 55 kg N ha-1 + vermicompost @1.25 t ha-1, 35 kg N ha-1 + vermicompost @2.5 t ha-1 and vermicompost @5 t ha-1. The experiment was laid out in a Randomized Complete Block Design with three replications. At harvest, both the spacing of 20 cm × 20 cm and 20 cm × 15 cm produced the tallest plants, the highest number of total tillers hill-1 and effective tillers hill-1. The highest grain yield (3.59 t ha-1) was recorded in 20 cm × 15 cm spacing which was at par with the grain yield (3.52 t ha-1) in 20 cm × 10 cm spacing. The 20 cm × 10 cm spacing also produced the highest straw yield (4.88 t ha-1) and biological yield (8.40 t ha-1). The lowest grain, straw and biological yields were recorded at the wider spacing of 20 cm × 20 cm. In contrast, the highest grain yield (3.79 t ha-1), straw yield (4.99 t ha-1) and biological yield (8.79 t ha-1) were found in 75 kg N ha-1 which was as good as the yields of 55 kg N ha-1 N+ vermicompost @1.25 t ha-1. The highest number of total tillers hill-1 (14.11) and effective tillers hill-1 (12.67) were found in the interaction effect of 20 cm × 20 cm spacing with 75 kg N ha-1. The interaction between 20 cm × 15 cm and 55 kg N ha-1 N+ vermicompost @1.25 t ha-1 gave the highest grain yield (4.58 t ha-1), straw yield (5.71 t ha-1) and biological yield (10.29 t ha-1). The lowest grain yield (2.03 t ha-1), straw yield (3.49 t ha-1) and biological yield (5.52 t ha-1) were found in the interaction between 20 cm × 20 cm and no nitrogen. Therefore, usage of 20 cm × 15 cm spacing fertilized with 55 kg N ha-1 + vermicompost @1.25 t ha-1 appeared as the promising practice of transplant Aus rice cv. (Parija) cultivation.

Production and productivity of green gram is governed by environmental, genotypic trait of the crop and crop management. The more specific reason for low production and productivity of pulses is the cultivation of local old varieties under marginally fertile lands and low input management conditions. Recently, high yielding varieties of green gram have been developed and evaluation of these varieties under various management conditions will be of great importance. In this view the study was conducted to investigate the growth and yield response of different green gram varieties in Kitui and Makueni counties in Kenya. Three green gram varieties (KS20, KAT 00308 and KAT 00309) were laid out in a randomized complete block design and replicated three times. The varieties differed significantly (P≤0.05) in plant height, number of effective nodules, 100-grain mass and grain yield in both sites. Variety KS20 was the tallest in both sites in all the stages while KAT00309 was the shortest. Variety (KS20) had the highest number of effective nodules in Ithookwe (11) and Kiboko (39) with the lowest were recorded for variety KAT00308. Days to 50% flowering and maturity were different between the varieties, and KS20 had the shortest where it was recorded that the periods were shorter in Kiboko by >15 days compared to Ithookwe. In both sites, the highest grain yield was recorded for KAT00309 with 2898 kg/ha and 1568 kg/ha in Kiboko and Ithookwe, respectively. There were no signficant differences on the biological yield between the varieties but the 100-grain mass differed signficantly in both sites where variety KAT00309 was the heaviest with 7.8 g and 6.9 g in Kiboko and Ithookwe, respectively. It was concluded that variety KAT00309 could lead to the highest grain yield in both Kitui and Makueni counties under water stress conditions of the two counties.

Rajma (Phaseolus vulgaris L) known as the common bean, French bean, kidney bean, bush bean, and pole bean is the most important grain legume of Nepal which covers about 10,529 ha areas along with the productivity of 1477kgha-1. Generally it is grown during summer in mid/high hills and during winter (post rainy) season interai/inner terai in rice and maize based eco-system. Now Rajma bean is being popular as the cash crop in the province 3, 5 and 6 because of producing organic products and tastier quality. Multi-environment trials was carried out at Nepalgunj, Parwanipur, Itahari and Surkhet during the winter season of 2014-2017 comprised of 10 diverse Rajma genotypes in Randomized Complete Block Design with three replications in order to evaluate the quantitative variation with respect to yield and yield contributing traits. The combined analysis of variance showed that the highly significant differences among the genotypes and locations in the traits like days to flowering, days to maturity, plant height, hundred seed weight and grain yield. However; there was not any GxE interaction effect found in days to flowering, days to maturity and grain yield. Mean yield performances showed that the genotype PDR-14 (2341kgha-1) produced the highest yield followed by Utkarsh (2332kgha-1) and Arun-2 (2021kgha-1). In conclusion, PDR-14 gave 9-56% higher yield among the genotypes and its stability analysis test also indicated that PDR-14 was found a highly stable across the environments and over the years. Variegated red kidney shape seed, white flowers along with dwarf and glabrous leaf pubescence is the DUS trait of the PDR-14 and recommended for terai/inner terai to high hills.

The study was conducted with aim to investigate growing possibilities without irrigating by taking advantage of spring rains at different sowing times as spring in Isparta conditions. The research was set up as field study during the 2009 and 2010 years according to Randomized Complete Block Design with three replications included six sowing dates 1st March, 10st March, 20th March, 30st March, 9th April and 18st April (control) by using Aktaş buckwheat cultivar. 18st April sowing time was irrigated as control, and the other sowing times was not watered and cultivated depending on natural rains. Buckwheat seeds emergence at 1st and 10st March sowing times, but all the plants after emergence died due to frost damage. Effect of sowing dates on plant height, biological yield and grain yield were statistically significant, and the longest plant height 65.9 cm and 60.0 cm, the highest biological yield 427.3 kg da-1 and 403.7 kg da-1 and grain yield 145.7 kg da-1 and 132.8 kg da-1, respectively, were determined in watered treatment in 18st April in both years (2015 and 2016). Effect of sowing dates on 1000 grain weight, hectoliter weight and protein content were statistically non-significant. It was concluded that buckwheat should be cultivation by watered for Isparta ecological conditions.

This study was carried out at National Maize Research Program, Rampur, Chitwan, Nepal to evaluate the effect of sowing dates on growth and grain yield of maize inbred lines. Seven maize inbred lines namely NML-2, RML-17, RML-32, RML-4, RML-86, RML-95 and RML-96 were planted on three different dates i.e. September 02, September 12, September 22, 2015 during winter using randomized complete block design with two replications. The results of this study showed that the growth and yield traits were significantly affected by various planting dates. The inbred line RML-17 produced the highest grain yield where as NML-2 gave the lowest yield during winter season. The highest yield was obtained when inbred lines were planted on September 12 and the lowest yield on September 2. The planting from September 2 to September 12 increased the grain yield. The delay in planting i.e. September 22 decreased grain yield. Therefore September 12 planting was suitable for inbred lines to maximize grain yield production.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during November 2014 to April 2015 to investigate the effect of planting spacing and nitrogen levels on yield attributes and yield of maize cv. Khaibhutta. The experiment comprised three nitrogen levels viz. 50, 100 and 150 kg N ha-1 and five plant spacings viz. 75 cm × 25 cm, 75 cm × 20 cm, 50 cm × 25 cm, 50 cm × 20 cm and 100 cm × 20 cm. The experiment was laid out in a randomized complete block design with three replications. Results revealed that nitrogen levels and plant spacing had significant effect on yield attributes and yield of Khaibhutta. The highest number of cobs plant-1, grains row-1, grain yield and stover yield were recorded with 150 kg N ha-1 followed by 100 kg N ha- 1and the lowest values were observed in 50 kg N ha-1. The highest number of cobs plant-1, grain rows cob-1, grains row-1, grains cob-1, 1000-grain weight, grain yield and harvest index were recorded at 75 cm × 25 cm spacing. In contrast, the closest spacing of 50 cm x 20 cm produced the lowest values of grain rows cob-1, grains row-1, grains cob-1, 1000-grain weight and grain yield. In case of interaction, the highest grain yield and harvest index were obtained at 75 cm × 25 cm spacing fertilized with 150 kg N ha-1. The lowest values of the above parameters were recorded in the closest spacing 50 cm × 20 cm with 50 kg N ha-1. From this study it may be concluded that maize (cv. Khaibhutta) can be cultivated at the spacing of 75 cm × 25 cm with 150 kg N ha-1 for appreciable grain yield.J. Bangladesh Agril. Univ. 14(1): 43-48, June 2016
