The experiment on evaluation of open pollinated genotypes of Yard long bean (Vigna unguiculata ssp. sesquipedalis) was conducted during summer season of 2016 and 2017 at Horticulture Research Division, Khumaltar Lalitpur to assess the variability in the genotypes and yield potentiality for commercial production. The experiment was laid out in Randomized Complete Block Design with three replications. Six genotypes viz. Great Wall 01, Great Wall 02, Great Wall 03, Great Wall 04 and Great Wall 08 were compared with Khumal Tane. Observations were recorded on fresh pod yield and yield attributing parameters. The plant vigor and plant uniformity score (1-5 scale) was not found significantly different among the tested genotypes. The highest number of pods per plant (46) was observed on the variety Great Wall 03 and the lowest number of pods (33) on Great Wall 01 followed by Khumal Tane (39). The fresh pod yield was noted the highest with Great wall 03 (24 t/ha) followed by Great Wall 2 (19.4 t/ha). The lowest yield was observed with Khumal Tane (12.7 t/ha). Likewise, Great Wall 03 was found tender whitish with green color when it matures and spongy type of fruit with mid early maturity (85-95 days) along with long harvesting period of 30-35 days. Although Great Wall 02 scored 4.7 in plant uniformity (1-5 scale) and 4.4 in plant vigor (1-5 scale) it was characterized as thick fleshy and whitish green color at maturity with smooth straight type flesh having early maturity (70-80 days) which could gain the demand of the market early compared to most popular Khumal Tane. Thus, among all genotypes Great Wall 03 and Great Wall 02 were recorded best for further evaluation and recommendation.

Yard long bean (Vigna unguiculata var. sesquipedalis L.) is one of the important leguminous vegetables in Bangladesh. However, yield of this vegetable is much lower in Bangladesh compared to other yard long beangrowing countries. Therefore, it is crucial to improve the yield of this vegetable. In the present study, genetic variability, heritability, character association and genetic diversity were evaluated on randomized complete block design with three replications among seven-yard-long bean genotypes. The genotypes were significantly variable for the studied characters. High genotypic and phenotypic coefficient of variation was observed in number of pods per plant and pod yield per plant. Accordingly, high heritability together with high genetic advance in percent of mean was observed in number of pod per plant, pod diameter and hundred seed weight. The correlation studies revealed that pod yield per plant showed significant positive correlation with number of seed per pod, number of pods per plant while significantly negative correlation with days to marketable harvest at both genotypic and phenotypic level. Path analysis revealed days to first flowering, days to maturity, number of pods per plant, pod weight and number of seeds per pod had direct positive effect on pod yield per plant. The studied genotypes were clustered into 3 groups with highest of inter-cluster distance between cluster I and III while lowest between cluster II and III. The genotypes of cluster I exhibited higher mean performance while lower in cluster III for important traits including pod yield per plant.

Abstract Litter sizes in commercial pig production have increased substantially over recent years; however, farrowing pen sizes have generally not changed over the same time period. The objective of this study was to evaluate the effect of farrowing pen size on piglet pre-weaning growth and mortality. Differences in pen size were created by varying the width of pens of the same length, increasing the creep area available to the piglets. The study used a total of 1,786 litters in a randomized complete block design to compare two Farrowing Pen Size treatments (FPS): Standard (pen width 1.52 m) and Increased (pen width 1.68 m). Litter sizes were equalized across treatments (12.9 ± 1.95 piglets) at 24 h after birth using cross-fostering. Litter weights were collected at birth and weaning (21.3 ± 2.08 d); pre-weaning mortality was recorded. The experimental unit was the litter; models included FPS and replicate. Farrowing Pen Size had no effect (P > 0.05) on litter size at birth (12.8 and 13.0 for the Standard and Increased FPS, respectively), after cross-fostering (12.9 for both treatments), or at weaning (11.2 and 11.3, respectively). There was no effect (P > 0.05) of FPS on total litter or average piglet weight at birth, after cross-fostering, and at weaning. These results suggest no benefit in piglet performance from increasing the width of farrowing pens. As litter sizes continue to increase in commercial production, further research is warranted to re-evaluate the impact of farrowing pen size on pre-weaning mortality.

An experiment was conducted during March 2014 to August 2014 at the experimental field of Sylhet Agricultural University (SAU), Sylhet to study the morphological variability, yield and yield contributing characteristics among the four lablab bean genotypes viz., SB003, SB010-1, SB011 and BP003. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The genotypes SB003 and SB010-1 had reddish brown seed coat color while it was black in SB011 and reddish color in the genotype BP003. Among the genotypes 100 dry seed weight was ranged from 34.00 g (SB010-1) to 42.00 g (SB011). Variation in yield and yield contributing characteristics were found among four lablab bean genotypes. The genotype SB003 produced the maximum number of pods plant-1 (206.3) followed by SB010-1 (134.3) while it was minimum for the genotype SB011 (92.67). Similar trend was also noticed in case of pod yield plant-1 among the genotypes. The highest pod yield was recorded in the genotype SB010 (7.73 ton ha-1) while it was the lowest in SB011 (2.87 ton ha-1). However, pod yield ha-1 indicating bright scope to popularize lablab bean production during early kharif in Sylhet region.

Crop yields in Finland are limited by many factors, such as the short growing season and spring drought. Thus earliness is an important breeding goal in Finnish agriculture, and is especially needed in some crops such as faba bean that have a longer growing period than cereals. During 2009-2011, 400 accessions of faba bean (Vicia faba L.) from 34 countries were evaluated for morpho-physiological traits related to drought resistance and the earliest accessions were identified. The four earliest accessions, from Cyprus and Syria, were sown in a pot experiment, together with Kontu and Witkiem Manita (an early-flowering, large-seeded Dutch cultivar) in order to determine days to flowering, podding and maturity under controlled conditions. The experiment was conducted in a randomized complete block design with 3 replicates. There were highly significant differences for all studied traits (p<0.001). Accessions D497, D557 and D505 had significantly faster progress to flowering and podding compared to Kontu. Accession D497 was the earliest genotype with 947 GDD (Growing degree-days to maturity), followed by accession D557 (985 GDD), and Kontu and Witkiem Manita were latest accessions in this study (1165 and 1159 GDD, respectively). The linkage of early flowering and early maturity to large seed size needs to be tested. These accessions may be valuable sources of earliness that could be used in faba bean breeding for short seasons such as those in Finland.

Abstract: The objective of this work was to evaluate the agro-economic efficiency of immature cowpea-radish intercropping systems in a semiarid environment in Brazil. The experiments were carried out in two cropping seasons, in a randomized complete block design with four replicates. The treatments consisted of a 4x2 factorial arrangement for the combination of four cowpea (Vigna unguiculata) cultivars (BRS Tumucumaque, BRS Cauamé, BRS Guariba, and BRS Itaim) and two radish (Raphanus sativus) cultivars (Crimson Gigante and Zapp). The agro-economic indices - system productivity index (SPI), land equivalent coefficient (LEC), and monetary equivalent ratio (MER) - were obtained using single plots of each cultivar in each block. 'BRS Tumucumaque' and 'BRS Guariba' showed the highest productivity of immature cowpea pods, and 'Crimson Gigante' showed the highest yield of marketable radish roots. The cultivation of either 'BRS Tumucumaque' or 'BRS Guariba' cowpea with 'Crimson Gigante' radish provides a greater agro-economy efficiency and sustainability for immature cowpea-radish intercropping.

A field experiment was carried out at the experimental field of Department of Genetics and Plant Breeding of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur during November 2008 through April 2009 to find out the performance of different pea varieties at different harvesting time. The treatments consisted of two factors, which were four harvesting times (70, 80, 90 and 100 days after sowing) and six varieties of garden pea (IPSA Motor shuti-1, IPSA Motor shuti-2, IPSA Motor shuti-3, BARI Motor shuti-1, BARI Motor shuti-3 and Local white). The experiment was laid out in a randomized complete block design with three replications. The maximum pod yield (11.42 t ha-1) was obtained from BARI Motor shuti-1 harvesting at 80 days after sowing which was statistically similar to IPSA Motor shuti-2  harvesting at 80 days after sowing and Local white at same harvesting date and superior to the rest of the treatment combination. The lowest pod yield (5.25 t ha-1) was produced by BARI Motor shuti-1 harvesting at 70 days after sowing.Bangladesh Agron. J. 2014, 17(2): 21-28

The potential of a crop to favorably respond to breeding programs depends on its existing nature and magnitude of genetic variability, heritability and genetic advance. An experiment was conducted with eighteen Brassica genotypes following Randomized complete block design (RCBD) with three replications at the field of the department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh, Bangladesh to estimate genetic divergence, variability ranges and contribution of each trait towards genetic diversity. Analysis of variance showed significant variation among the genotypes for all the studied yield and yield contributing characters. The phenotypic co-efficient of variation (PCV) was higher than the genotypic co-efficient of variation (GCV) for all the characters measured, indicated that the traits were influenced by environment. All traits showed high heritability (61.54% to 98.64%) which indicated possible improvement through selection. High heritability values (>60%) along with high genetic advance and genetic advance in percentage of mean indicated prevalence of additive gene action, which provides good scope for further improvement by selection. The genotypes were grouped into four clusters, most of the genotypes were grouped into Custer I (8 genotypes), while cluster IV contained only one genotype. Considering the mean value, the cluster IV and Cluster II were ranked as the top groups in terms of yield and early maturity. High Heritability with high genetic advance in percentage of mean was observed for number of branches/plant, number of pod/plant, number of seeds/pod and yield/plant and selection focused   on these traits could be useful for future breeding program of Brassica. The genotype BD-7114 was the best performer considering all the studied traits especially yield and days to maturity which could be used as an important breeding material for the improvement of Brassica.
