Oxide Particles

This study was performed to determine the effect of nano-iron oxide on soybean yield and quality. Field experiment was designed based on randomized complete block design with three replications. Treatments were five levels of nano-iron oxide (0, 0.25, 0.5, 0.75 and 1 g l-1). Results showed that nano-iron oxide at the concentration of 0.75 g l-1 was increased leaf + pod dry weight and pod dry weight. The highest grain yield was observed with using 0.5 g l-1 nano-iron oxide that showed 48% increase in grain yield in comparison with control. Other measured traits were not affected by the iron nano- particles.

For upland rice, it is desired, among many objectives, to obtain highly productive and early genotypes, consequently reducing the risk of establishing a crop regarding climatic adversities. Therefore, this study aimed to verify the correlation between the agronomic traits days to flowering and grain yield of 14 upland rice lines. The experiment was conducted in seven environments, in the 2013/14, 2014/15 and 2015/16 crop years, in a randomized complete block design with three replications. Both the genotypic and phenotypic correlation were significant and positive, whereas the genotype correlation was superior to the phenotype. However, it was noted a low magnitude of the correlation values. It was concluded that a favorable and simultaneous selection is possible for high grain yield and plants with early blossoming cycle in upland rice.

Ethiopia is one of the famous and major producers of sesame in sub-Saharan Africa, and Ethiopian sesame is among the highest quality in the world. The experiment was conducted in Northern Ethiopia for three growing seasons (2013–2015) under a rain fed condition with the objective of identifying high-yielding genotypes and their agronomic traits. The experiment consisted of twelve genotypes laid down in randomized complete block design with three replications. The genotype, year, and genotype × year interaction components showed statistically highly significant variation (p<0.001) for most of the agronomic traits which clearly confirms the presence of genotype × year interaction in this study. The highest combined mean grain yield (906.3 kg/ha) was obtained from Hirhir followed by Serkamo white (756.5 kg/ha), and from the three growing seasons, the highest grain yield (1161.5 kg/ha) was recorded from Hirhir grown in the second growing season (2014). The growing seasons were different from one another in allowing the genotypes to have a different performance, and all of the agronomic traits, except thousand seed weight, were statistically different across the three growing seasons. In the ordination of the genotypes and agronomic traits, PCA1, which accounted for 38.3% of the variation, was positively associated with grain yield, branches per plant, length of the pod-bearing zone, plant height, number of pods per plant, number of seeds per pod, and thousand seed weight. On the contrary, PCA2, which accounted for 19.7% of the variation, was positively associated with days to 50% flowering and days to 50% maturity.

To find out exactly how sowing density and sowing pattern affect soybean grain yield, quality and its components in non-traditional soybean growing regions, such as Germany, two field trials have been conducted at two locations in Bavaria in 2016 and 2017. The experiments were carried out with four sowing densities (30, 50, 70, 90 seeds/m<sup>2</sup>) and four cultivars from different maturity groups (Viola 000, Lissabon 000, ES Mentor 00, Orion 00) as randomized complete block design with four replicates. Almost all evaluated traits varied significantly depending on year × location. There was no interaction between the main factors (cultivar × sowing density). The results revealed that grain yield and height of the first pod increased with increase of sowing density. The number of pods per plant and branching decreased with increasing sowing density. At higher sowing densities at flowering leaf area index was significantly higher than at lower sowing densities. The cv. ES Mentor (00) with 70 seeds/m<sup>2</sup> has proved to be a suitable cultivar in terms of yield and quality in southern Germany (&gt; 3.6 t/ha grain yield and 40% protein).

A series of tropical maize hybrids, involving 10 single, four double and four three-way crosses were evaluated with their parental inbred lines and three control varieties, at Universiti Putra Malaysia, Serdang, Malaysia, in a randomized complete block design, with three replications. The objectives were to identify hybrids superior for yield, yield components and other agronomic traits, to estimate heterosis revealed by the hybrids, and to estimate broad-sense heritability for important characters in the populations. The hybrids were found to vary highly for grain yield and most other traits measured. High estimates of heterosis were shown by grain yield, ear weight and grain weight per ear, moderate for plant and ear heights, shelling percentage, ear diameter, number of kernel rows per ear, number of kernels per ear row and 100-grain weight. The hybrids flowered and matured earlier than their respective inbred parents. Estimates of broad-sense heritability also varied with characters. Moderate heritability was shown for grain yield indicating a substantial amount of genetic variation in this population of hybrids. Low and negligible heritability for days to silking and 100-grain weight indicate that these traits were very much influenced by environmental factors. Based on the overall performance of the hybrids, the single cross, SC-2, the double cross, DC-11 and the three-way cross, TWC-15, were found to have high potential. No obvious differences were observed in performance among the three categories of hybrids, the single, double and three-way crosses.

Effects of lime and gypsum applications on the quality of soybeans grown under no-till (NT) are not well defined yet. A field trial established in 1998 on a dystrophic clayey Rhodic Hapludox, at Ponta Grossa, State of Paraná, Brazil, evaluated grain yield and soybean quality based on oil, protein and nutrient content, after lime and gypsum applications under NT, in a randomized complete block design (n = 3), split-plot experiment. In the main plots, the treatments with dolomitic lime were: control (no lime), split application of lime on the surface (three yearly applications of 1.5 Mg ha¹), surface lime (4.5 Mg ha¹), and incorporated lime (4.5 Mg ha¹). Subplots received four different rates of gypsum: 0, 3, 6, and 9 Mg ha-1. The soybean crop was evaluated in the agricultural years of 20022003 and 20032004. After 58 months, the correction of acidity through surface liming, with full or split rates, was more pronounced in the top layer (00.05 m) and there was greater reaction at the depths of 0.050.10 and 0.100.20 m when lime was incorporated. Surface or incorporated liming had no effect on grain yield, soybean oil and protein content. Gypsum improved chemical subsoil conditions, raising pH (0.01 mol L-1 CaCl2) as well as Ca2+ and S-SO4(2-) contents; it also caused exchangeable Mg2+ leaching in the soil profile. The application of gypsum did not affect grain yield, yet it improved soybean quality through an increase in protein and S contents, in 20032004, and in grain P, K and Ca, in the two cropping years. The use of gypsum in NT soybeans can be especially important for fields of seeds production.

Aim: To evaluate under agro-environmental conditions of Gimbi research station, some agronomic traits of four groundnut varieties from germplasm of PNL. Study Design: This study was conducted using a randomized complete block design with four treatments repeated three times. Place and Duration of the Study: The study was conducted in Gimbi research station between October 2019 and January 2020 (i.e. 4 months).  Methodology: Trial was conducted using four treatments with three replications. Data collected concerned percentage of seedlings emerged, number of days between sowing and flowering 50%, dry pod weight, weight of unsorted seed, weight of sorted seeds, percentage of good seeds, shelling percentage, average weight of 1,000 seeds and grain yield per hectare. All data were submitted to analysis of variance at 5% probability level.    Results: The rate of seedlings emerged recorded on each groundnut variety was overall less than 50%. All varieties flowered 32 days after sowing. The highest average weight of dry pods (410.8g) was noted on A1408, while the lowest value of dry pod weight (310.6g) was observed on JL24. The highest weight of unsorted seeds (360.9g) was recorded on A1408, while the lowest value (260.7g) was observed on JL24. Variety A1408 presented the highest weight of stored seeds (350.5g), while the lowest value (250.8g) was noted on variety JL24. The highest percentage of good seeds (97.3) was obtained on A1408, while variety Sivi presented the lowest percentage of good seeds (93.2). The highest shelling percentage of groundnut pods (87.6) was obtained on A1408, while the lowest shelling percentage (83.5) was noted on JL24. The lowest weight of 1,000 seeds was noted on Sivi variety (484.6g), and the highest value was recorded on A1408 (522.6g). The highest grain yield (912.9Kg.ha-1) was obtained on variety A1408, while the lowest grain yield was noted on JL24 (690Kg.ha-1). Conclusion: Seeds of all varieties presented a very low rate of emergence (less than 50%). Variety A1408 was more productive than other varieties, and variety JL24 used as control should be regarded as having degenerated.

Abstract A field study was carried out during the spring season of 2017 in the fields of a farmer in the district of Habbaniyah, which is 70 km west of Baghdad, to study the effect of three planting dates (15 March, 1 April and 15 April) on the growth, yield and quality of three cultivars of sorghum (Babel, Warka and Rabeh). The implementation of the experiment was according to a randomized complete block design (R.C.B.D) with split-plot arrangement with three replications. The results of the experiment indicated that the cultivar Rabeh was superior in most of the studied traits such as leaf area (3968 cm2), number of grains per head (2659.00 grains head-1), weight of grains per head (63.41 g) and grain yield (7.44 ton ha-1), while the Babel variety was superior in the percentage of protein (12.21%). As for planting dates, the date of April 1 was superior in most of the studied traits, such as leaf area (3635.33 cm2), number of grains per head (2670.33 grains head-1), weight of grains per head (62.12 g), grain yield (7.55 ton ha-1) and the percentage of protein (11.49%).

Rice is a staple food for more than half of the world’s population and to increase the yield potential of rice would be a key factor for mitigating global demands of about 810 million tons of rice by 2025. To exploit the economic importance of heterosis, quantitative valuation was carried out in a randomized complete block design with three replications for 16 agronomic traits of 5x5 half diallel populations during boro season of 2017-2018. Diallel populations were generated by using five selected parents (P1: BRRI dhan28, P2: BRRI dhan74, P3: BINA dhan10, P4: IR59418-7B-21-3 and P5: BRRI dhan67) where, P1 was considered as standard check to estimate the economic heterosis. Analysis of variance revealed highly significant variability among the genotypes for most of the traits except grain length and length-breadth ratio. The results showed that none of the hybrid combination performed better for all the traits over the three types of heterosis. The highest relative heterosis was recorded in P3×P4 followed by P4×P5 for grain yield plant-1, filled grains panicle-1, effective tillers plant-1. Majority of the cross combinations (>60%) revealed highly significant positive heterosis for grain yield plant-1 over mid parent. Heterobeltiosis for grain yield plant-1 was observed significant for 50% cross combinations and could be utilized in hybrid breeding. Whereas, more than 70% crosses exhibited undesirable negative standard heterosis for grain yield plant-1. Only two cross combinations (P3×P5 and P3×P4) among ten revealed significant positive economic heterosis for grain yield plant-1 and those could be exploited in rice breeding. Int. J. Appl. Sci.

An experiment was carried out at the Agronomy Field laboratory of Bangladesh Agricultural University, Mymensingh during the period from November 2015 to March 2016 to study the effect of cultivar and seed rate on weed infestation and crop performance of wheat. Three wheat cultivars viz. BARI Gom 22, BARI Gom 23 and BARI Gom 24 and four seed rates viz. 80, 100, 120 and 140 kg ha-1 were taken as the experimental treatment. The experiment was carried out in randomized complete block design (RCBD) with three replications. The cultivar and seed rate significantly influenced weed infestation and crop performance of wheat. The dry weight of weeds under cultivar BARI Gom 24 was the lowest (4.18 g m-2) compared to other cultivars. The lowest dry weight of weed was recorded in the seed rate of 120 kg ha-1 (3.67 g m-2) and the highest one (6.69 g m-2) was produced under the seed rate of 80 kg ha-1. The highest number of effective tillers plant-1 (4.05), total number of tillers plant-1 (4.53), number of grain spike-1 (19.85) and grain yield (1.56 g) were produced by BARI Gom 24. BARI Gom 24 produced the highest grain yield (1.56 t ha-1) which was as good as BARI Gom 22 (1.40 t ha-1). BARI Gom 24 produced the highest grain yield with 100 kg seed rate and also a good competitor against weeds. Seed rate was a reliable factor where increasing seed rate reduced the intensity of weed infestation and weed dry weight production. In conclusion, cultivation of BARI Gom 24 at the rate of 120 kg ha-1 seeds may be cultivated for higher grain yield. Res. Agric., Livest. Fish.8(1): 1-8, April 2021

An experiment was carried out at the Agronomy Field laboratory of Bangladesh Agricultural University, Mymensingh during the period from November 2014 to March 2015 to study the effect of cultivar and seed rate on weed infestation and crop performance of wheat. Three wheat cultivars viz. BARI Gam 24, BARI Gam 25 and BARI Gam 26 and five seed rates viz. 80, 90, 100, 110 and 120 kg ha-1 were considered as the experimental treatment. The experiment was carried out in Randomized Complete Block Design with three replications. The cultivar and seed rate were significantly influenced on weed infestation and crop performance of wheat. The dry weight of weeds in cultivar BARI Gam 26 was the lowest (9.24 g m-2) compared to other cultivars. The lowest dry weight of weed was recorded in the seed rate of 120 kg ha-1 (7.57 g m-2) and the highest one (16.14 g m-2) was produced in seed rate of 80 kg ha-1. The highest plant height (93.27 cm), number of effective tillers plant-1 (3.69) and 1000-grain weight (44.51g) were produced in BARI Gam 25. The highest number of spikelet spike-1 (18.12) and grains spike-1 (34.51) were produced by BARI Gam 26. BARI Gam 26 produced the highest grain yield (2.51 t ha-1) which was as good as BARI Gam 25 (2.48 t ha-1). BARI Gam 26 produced the highest grain yield with 100 kg seed rate and also a good competitor against weeds. Seed rate was a reliable factor where increasing seed rate reduced the weed dry weight production. In conclusion, cultivation of BARI Gam 26 @100 kg ha-1 seeds may be cultivated for higher grain yield.Progressive Agriculture 27 (1): 20-26, 2016
