Selected forty F2 single plant progenies of a lentil cross viz., L-830 × MC-6 and bulked seeds were evaluated in a randomized block design with two replications for secondary branches per plant, pods per plant, seed yield per plant and seed index as independent selection criteria. Out of the four selection criterion, highest realized selection response in percentage was recorded for pods per plant (37.42 %), and was followed by secondary branches per plant (28.5 %). The realized correlated response to selection for seed yield per plant was significant under the selection criteria number of pods per plant. Thus the selection criteria pods per plant was more effective than other selection criterion.

Combining ability and heterosis were calculated for fourteen lines of linseed in a line × tester mating design using twelve lines and two diverse testers in two different environments. The hybrids and parental lines were raised in a completely randomized block design with three replications to investigate seed and fibre yield and their component traits. Genetic variation was significant for most of the traits over environments. Combining ability studies revealed that the lines KL-221 and LCK-9826 were good general combiners for seed yield and most of its components, whereas LMH-62 and LC-2323 were good general combiners for yield components only. Moreover, KL-221 was also a good general combiner for fibre yield. Similarly, B-509 and Ariane were good general combiners for fibre yield and most of its components. Among the specific cross combinations, B-509 × Flak-1 was outstanding for seed yield per plant and B-509 × KL-187 and LC-2323 × LCK-9826 for fibre yield per plant, with high SCA effects. In general, the hybrids excelled their respective parents and the standard checks for most of the characters studied. Based on the comparison of mean performance, SCA effects and the extent of heterosis, the hybrids LC-2323 × LCK-9826 and B-509 × KL-221 appeared to be the most promising for both seed and fibre yield. Other promising combinations were LC-2323 × KL-210 and B-509 × Ariane for seed and fibre yield, respectively. The superiority of LC-2323, LCK-9826, KL-221, B-509 and Ariane as good general combiners was further confirmed by the involvement of these parents in the desirable cross combinations.

The present investigation was conducted using 28 different genotypes (seven parents and their 21 F1s) of maize under organic conditions at the Rain-fed Organic Research Farm, Narayanbag, Institute of Agricultural Sciences, Bundelkhand University, Jhansi (U.P.) India, during kharif 2018 and rabi season 2018-19. In order to determine the general and specific combining ability of parents and the crosses, the growth parameters and yield components were evaluated in a 7×7 diallel fashion in maize in a Randomized Block Design (RBD) with three replications. In this study, the GCA effects suggested that parent P1, P2 and P4 were the most desirable as they possessed high GCA effect for most of the characters. Among F1 crosses, P4 x P3, P3 x P1, P5 x P3 and P7 x P5 having significant positive SCA were found to be desirable for yield and yield attributing characters. The maximum heterotic effects in desirable direction for yield attributes were showed by the cross combinations viz; P1 x P6, P2 x P7, P2 x P5, P1 x P2, P3 x P4, P5 x P7 and P3 x P5. The maximum heterosis was recorded in for Seed yield per plant P5 x P7 (39.32%) which ranged from -14.69 to 49.55.

Yield Formation of White Lupin Lupinus albus L. on Heavy Gleyey Alluvial Soil Field trial with white lupin Lupinus albus L., an anti-trypsin-free French cultivar Amiga, on heavy gleyey alluvial soil of the research base in Milhostov (alt.: 101 m, avg. year temp.: 9.0°C, year precip.: 559 mm) in the trial years of 2006-2008 was performed. The influence of three seeding rates: 0.55, 0.65, 0.75 million viable seeds per ha (MVS) and three doses of N fertilization: 25, 50, 75 kg ha-1 N on seed yield and yield components such as plant number per m2, pod number per plant, seed number per plant and thousand seed weight was tested in the trial. The data of randomized complete block design trial were statistically evaluated by ANOVA and LSD method. All tested factors had highly significant (P≤0.01) influence on seed yield. Seed yield was especially influenced by weather in year (97.8% influence), followed by seeding rate with the influence of 1.8% and N fertilization with the influence of 0.3% only. The highest seed yield of 2.21 t ha-1 was under the highest seeding rate of 0.75 MVS with the difference of 0.36 t ha-1 (19.5%) in comparison with the lowest seeding rate of 0.55 MVS (1.85 t ha-1) and about 0.15 t ha-1 (10.7%) higher in comparison with the seeding rate of 0.65 MVS (2.06 t ha-1). The highest influence on seed yield had the dose of 75 kg ha-1 N. The seed yield of 2.09 t ha-1 under the treatment with the highest dose of 75 kg ha-1 N was about 0.13 t ha-1 (6.6%) higher than the yield under the treatment with the lowest dose of 25 kg ha-1 N (1.96 t ha-1). All yield components were highly significantly (P≤0.01) influenced by weather in year. Plant number per m2 was also highly significantly (P≤0.01) influenced by all tested factors.

This research was conducted on 20 safflower genotypes and lasted 3 years (2014-2016) in the Central Anatolia Region of Turkey. The experiments were conducted in randomized block design with four replications. The relationships among yield 9 other traits in safflower genotypes were investigated. As the average of three years, the greatest seed yield (SY) was obtained from genotype G5 (PI 451952) with 3156.3 kg·ha-1. It was followed by genotypes G4 (PI 525458) and G9 (PI 306686) with 3013.2 and 2977.1 kg·ha-1, respectively. Among the standard cultivars, the greatest seed yield (2750.4 kg·ha-1) was obtained from the Dinçer cultivar. The greatest oil content (OC) was obtained from the genotype G11 (PI 537665) with 36.5%. It was followed by the genotypes G9 (PI 306686) (35.4%), G6 (PI 537598) (35.4%) and G14 (PI 560169) (35.3%). Oil contents varied between 29.1-36.5%. Yield-trait relationships were assessed through both correlation analysis and GT (Genotype by Trait) biplot analysis. Based on the results of the two approaches, plant height (PH), number of branches (NB), number of heads (NH) and thousand-seed weight (TSW) were identified as the most significant selection criteria for yield from safflower. The combined use of correlation and biplot analysis in the assessment of relationships among the traits improved the chance for success.

A field experiment was conducted during rabi 2007-08 to 2008-09 at Uttar Banga Krishi Viswavidyalaya, Cooch Behar situated at sub-Himalayan plains popularly known as terai region of West Bengal, India to study the productivity of yellow sarson under different nutrient management practices and seed priming methods. The experiment was laid out in a factorial randomized block design with eight nutrient management practices and three seed priming methods. The results showed marked improvement in yield components, productivity and economics of yellow sarson due to integrated nutrient management and seed priming methods. Significantly highest seed yield (1374 kg ha-1) was recorded with combination comprising FYM + Azotobacter + PSB and 75% of the recommended fertilizers. The integrated nutrient management practice also had greater impact in production economics, sustenance in soil fertility and enrichment of soil nutrients. The crop receiving plant nutrients only from chemical sources showed poor productivity leading to less remuneration. Higher seed oil content (41.8% and 42.2%) was obtained with the application of 100% of the recommended dose (60:30:30 kg N:P2O5:K2O kg ha-1) along with sulphur (20 kg ha-1) but the oil yield was not impressive due to poor seed yield. Pre-sowing soaking of seeds with 100 ppm KH2PO4 also showed improvement in yield components, productivity and oil yield of the yellow sarson crop compared to seeds soaked with 100 ppm Na2HPO4 and water. Net returns and return/rupee invested were higher when the yellow sarson seeds were soaked with 100 ppm KH2PO4 over the other soaking methods. Variations in residual fertility were not discernible due to seed soaking. DOI: http://dx.doi.org/10.3329/sja.v12i1.21117 SAARC J. Agri., 12(1): 106-116 (2014)

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.

An investigation consisting of 36 fenugreek genotypes and one check (Pusa Early Bunching) was laid out in Randomized Block Design with three replications at Pantnagar Centre for Plant Genetic Resources (PCPGR) of the G.B.P.U.A and T, Pantnagar, Uttarakhand during rabi season of 2016-17 and 2017-18 and observations were recorded on sixteen different traits. The traits viz., number of pods per plant, thousand seed weight and leaf yield per plant exhibited high direct effects on seed yield per plant along with significant positive correlation indicating that these traits can be used as most important selection criteria for seed yield improvement. The diversity analysis leads to formation of nine different clusters and maximum intra-cluster distance was observed in cluster IV (21.07) while highest inter-cluster distance was recorded between cluster VII and IV (46.07). These clusters actually represent the different heterotic pools and genotypes from diverse pools can be crossed to obtain heterosis and transgressive segregants.

A field experiment was conducted during rabi season of 2012-13 which consisted of two spacing viz., 30 cm x10 cm (S1), 22 cm x 10 cm (S2) and two fertilizer levels viz., F1- 40:40:20 kg NPK per ha, F2- 50:50:25 kg NPK per ha and three genotypes viz., Ajmer Fenugreek-1 (V1), Ajmer Fenugreek-3 (V2) and Ajmer Fenugreek-4 (V3). The experiment was laid out in factorial randomized block design with three replications. Result revealed that significantly higher seed yield (2437.4 kg ha-1), straw yield (3356.8 kg ha-1), biological yield (5794.2 ha-1), net return (Rs.57358 ha-1) and BCR (2.5) were recorded with sowing at a spacing of 22 cm x 10 cm as compared to 30 cm x 10 cm spacing but numbers of pods per plant (37.0), seed yield per plant (43.5 g), test weight (16.6 g) and harvest index (41.80) were higher in 30 cm x 10 cm spacing. Irrespective of spacing and genotypes, the application of 125 percent RDF ( NPK 50:50:25) recorded significantly more pods (40.7) per plant, seed yield (41.9 g) per plant, seed yield (2249.1 kgha-1), straw yield (3094.2 kgha-1), biological yield (5343.2 kgha-1), 1000 seed weight (16.4 g), harvest index (42.07), net return (Rs.51091.0 ha-1) and BCR (2.3) as compared to 100 percent RDF(NPK 40:20:20). Significantly higher number of pods (42.9/pod), seed yield (45.9 g/plant), seed yield (2270.7 kgha-1), straw yield (3066.8 kgha-1), biological yield (5337.4 kgha-1), net return (Rs.51927.0 ha-1) and BCR (2.3) were recorded with AFg-4. Thus, it is inferred that sowing at 22 cm x 10 cm spacing with application of 125 per cent of recommended dose of fertilizer is better for realizing higher yield, net return and BCR.
