Seed yield in soybean is associated with other yield components. The objective of the study was to investigate the pattern of relationship between seed yield and yield components in soybean. Agronomic characters and seed yield of 147 soybean homozygous lines (HL) and 3 check cultivars (Dega 1, Detap 1, and Anjasmoro) were evaluated in Banyuwangi (East Java, Indonesia) from April to July 2018. The field experiment was conducted in a randomized complete block design with 2 replications. After threshing, the HLs were grouped into large seed size (> 14.00 g/100 seeds) and medium seed size (10 - 14 g/100 seeds). The causation and inter-relationship between yield components and seed yield were quantified using path analysis. Based on the seed size, a total of 150 HLs was grouped into 97 lines and 53 lines of large and medium seed size, respectively. The correlation analysis showed a similar pattern between groups of large and medium seed size. The seed yield in both groups was highly determined by the characters of the number of filled pods, number of nodes, number of branches, plant height, and wet biomass. The results of path analysis revealed that plant age, particularly the length of the generative phase, was an important factor affecting seed yield in large seed soybean lines. The length of the generative phase determining the soybean yield in this study can be suggested to be used as selection criteria to obtain high yielding and large seed size variety.

Abstract The aim of this research was to evaluate the performance of yield and yield components of soybean genotypes, as well as the relationship pattern among characters that affect the seed yield. The research material consists of 145 F5 lines and five check cultivars, which were evaluated for their yield and yield components in Malang and Probolinggo, using a randomized block design with two replicates. The combined analysis of variance for yield and yield component showed a significant interaction effect between location and genotype for the number of branches, the number of empty pods, 100 seed weight, and seed yield. The performance of yield and yield components of soybean genotypes tested in Malang showed earlier maturity, taller plants, larger seed size, and higher seed yields when compared to research conducted in Probolinggo. In the selection for the best genotypes, ten genotypes were chosen for their large seed size criteria, while two genotypes were chosen for their relatively medium maturity (81 days) in the location of Malang. In Probolinggo, of the ten genotypes, three genotypes with medium maturity, and three genotypes with medium seed size. The selected genotypes will proceed to the stage of the advanced yield trial. The association study revealed that soybean yield has a positive correlation with plant height, number of nodes, number of branches, number of filled pods, days to flowering, and days to maturity. Those yield components could be used as selection criteria in the breeding program to obtain high-yielding soybean cultivars.

Transgressive Segregations

Although many interspecific crosses in Cicer species have successfully been carried out to improve the population in cultivated chickpea (Cicer arietinum L.), interspecific and backcross populations derived from mutants of Cicer species have not been studied for revealing suppressed genes responsible for heterotic effects and transgressive segregations. Therefore, the study aimed (i) to estimate heterosis (here, offspring superior to mid-parent value) and heterobeltiosis (offspring superior to better parent) for yield and yield components in the F1; (ii) to decipher transgressive segregation (extreme phenotypes) in F2 and backcross populations; and (iii) to reveal suppressed genes in interspecific and backcross populations (C. arietinum × F1 and C. reticulatum Ladiz.× F1) derived from interspecific crosses between a mutant of C. arietinum and a mutant of C. reticulatum. Heterobeltiosis was found for seed and biological yields, number of branches, and number of pods per plant in F1 progeny; heterosis was determined for the additional traits of 100-seed weight and harvest index. Heterobeltiosis and heterosis for yield and yield components in F1 progeny prompted transgressive segregation for these traits in F2 and backcross populations. In the backcrosses, C. arietinum × F1 crosses produced greater seed size and more pods per plant than C. reticulatum × F1, suggesting that C. arietinum × F1 backcrossing could improve yield components and lead to large seed size. Most of the high-yielding progeny in F2 and C. arietinum × F1 populations had double-podded nodes. It was concluded that the suppressed genes in a mutant of C. reticulatum or a mutant of C. arietinum played a crucial role in increasing transgressive segregations and allowing the cultivated chickpea to gain increased yield and yield components as well as large seed size.

Exposure of soybean to dicamba can result in leaf malformation and sometimes yield loss, but it is unclear how yield components are affected by exposure to low quantities of this herbicide. The objectives were to characterize soybean injury and quantify changes in seed yield and yield components of soybean plants exposed to dicamba, and determine if seed yield loss can be estimated from visual injury ratings. Nine dicamba rates (0, 0.06, 0.23, 0.57, 1.1, 2.3, 4.5, 9.1, and 22.7 g ae ha−1) were applied at three growth stages (V2 – two trifoliates, V5-five trifoliates, or R2-full flowering soybean) to Beck's brand ‘342NRR’ soybean planted near Lafayette, IN, in 2009 and 2010 and near Fowler, IN, in 2009. Visually estimated soybean injury of 20% at the V2, V5, or R2 timing was 0.676 to 0.937 g ha−1dicamba at 14 d after treatment (DAT) and 0.359 to 1.37 g ha−1dicamba at 28 DAT. Seed yield was reduced by 5% from 0.042 to 0.528 g ha−1dicamba and a 10% reduction was caused by 0.169 to 1.1 g ha−1dicamba. The number of seeds m−2, pods m−2, reproductive nodes m−2, and nodes m−2were the most sensitive yield components. Path analysis indicated that dicamba reduced seeds m−2, pods m−2, reproductive nodes m−2, and nodes m−2which were the main causes of seed yield loss from dicamba exposure. The correlation of seed yield loss and visual soybean injury was significant (P < 0.0001) for both the V2 treatment timing (R2= 0.92) and the V5 and R2 treatment timings (R2= 0.91). Early-season injury rating of 8% at the V2 treatment and 2% at the V5 or R2 treatments caused 10% or more yield loss.

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh, during November 2008 to March 2009 to examine the effects of mimosa (Mimosa invisa) compost and phosphorus on the yield and yield components of lentil variety BARI Masur6. Two factors were: a) Mimosa invisa compost and b) phosphorus fertilizer. Mimosa invisa compost were used in four rates- 1 (M1), 5 (M2), 10 (M3) and 15 (M4) t ha-1. Five rates of phosphorus fertilizer were: ‘no’ phosphorus (P0), 25% RDP (P1), 50% RDP (P2), 75% RDP (P3) and 100% recommended dose phosphorus (TSP @ 85 kg ha-1) (P4). The experiment was laid out in a factorial randomized complete block design with three replications. Mimosa invisa compost had significant effect on the crop characters except number of branches plant-1. The highest seed yield (1435.33 kg ha-1) was observed in M2 treatment (5 t ha-1) and the lowest seed yield (1220 kg ha-1) was observed in M4 treatment (15 t ha-1). Phosphorus had a significant effect on all the plant characters. The highest seed yield (1464.17 kg ha-1) was observed in P4 treatment (100% RDP) and the lowest was observed in P0 treatment. The interaction effect of Mimosa invisa compost and phosphorus on the yield of lentil was significant. The highest seed yield was observed (1630 kg ha-1) in M2×P4 treatment and the lowest was in M3×P0 treatment (1000 kg ha-1).

The experiment was carried out to study the effect of variety and level of phosphorus fertilizer on the yield and yield components of lentil at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during October 2009 to March 2010. Three lentil varieties viz. BINA masur 2, BINA masur 3 and BARI masur 4 and four levels of phosphorus viz. 0 kg P ha-1 (P0), 15 kg P ha-1 (P15), 30 kg P ha-1 (P30) and 45 kg P ha-1 (P45) were used in this experiment. Varieties showed significant influence on the all characters except plant height. The highest seed yield (1165 kg ha-1) was observed in BARI masur 4, and the lowest seed yield (1028 kg ha-1) was found in BINA masur 3. Phosphorus fertilizer had a significant effect on all the plant characters studied except 1000 seed weight. The highest seed yield (1222kg ha-1) was observed in P45 (45 kg P ha-1) treatment and the lowest seed yield (893 kg ha-1) was found in P0 treatment. In case of interaction, effect of cultivar and phosphorus fertilizer doses had a significant effect on all the plant characters studied except seeds pod-1 and 1000-seed weight. The highest seed yield (1317 kg ha-1) was obtained in V3 X P45 treatment, and the lowest seed yield (830 kg ha-1) was observed in V2 X P0 treatment combination. Among the varieties BINA masur 2 and BARI masur 4 were superior to BINA masur 3 in respect of yield performance with 30 kg P ha-1. BARI masur 4 fertilized with 30 kg P ha-1 produced the highest seed yield. Int. J. Agril. Res. Innov. & Tech. 3 (1): 78-82, June, 2013 DOI: http://dx.doi.org/10.3329/ijarit.v3i1.16097

Abstract In hot and arid regions, drought stress is considered as one of the main reasons for yield reduction. To study the effect of drought stress, iron and zinc spray on the yield and yield components of wheat, an experiment was carried out during the crop seasons of 2010 and 2011 on Shahid Salemi Farm in Ahwaz as a split factorial within randomized complete block design with three replications. The main plots with irrigation factor and three levels were considered: Level A) full irrigation, Level B) stopping irrigation at pollination step, and Level C) stopping irrigation at the seed filling stage. Subsidiary plots were considered with and without iron and zinc spray. Influencing the seed filling process, in interaction with iron, wich is an important leaf's chlorophyll cation, zinc increased the seed yield. The drought stress reduced the thousand kernels weight (TKW) and the number of seeds per spike increased about 24% and 8.5% more than the one of control treatment, respectively. Using iron, as compared with control treatment, causes the increase of thousand kernels weight from 45.71 to 46.83 grams and the increase of spike from 49.51 to 51.73. Zinc spray increased seed yield and thousand kernels weight. The results obtained from the present research showed that iron and zinc spray has fairly improved the effects caused by drought stress.
