Teff is a dominantly cultivated and stable crop in Ethiopia primarily grown for its grain which is used for preparing injera. In spite of its importance, the productivity is very low due to many factors among them, and poor agronomic practices are the major ones. In view of this, a field experiment, under rain-fed condition, was conducted at Laelay Machew district with the objective of evaluating the response of teff to seeding rate and methods of sowing during 2017/18 main cropping season. The experiment comprised four levels of seeding rate (10, 15, 20, and 25 kg/ha) and two methods of sowing (broad casting and row planting), and the experiment was laid in a 2 × 4 factorial arrangement in randomized complete block design (RCBD), replicated three times. Data related to phenology, growth, yield, and yield attributes were collected and analyzed using SAS software. Results indicated that days to panicle emergence, plant height, total number of tillers, productive tillers, main panicle seed weight, thousand-seed weight, panicle length, and harvest index were significantly (P<0.05) affected by the main effects of seeding rate and methods of sowing but these parameters showed no response to interaction effects of the two treatment factors. However, the interaction of the two treatment factors affected grain yield, biological yield, and straw yield. Plots sown with low seeding rate (10 kg/ha) combined with row planting gave high grain yield (2333 kg/ha), biological yield (7666 kg/ha), and straw yield (5333 kg/ha). Therefore, using treatment combinations of seeding rate of 10 kg·ha−1 together with the row method of sowing can be advised for teff production in the subhumid areas of central zone of Tigray.

This study was conducted to evaluate the efficacy of different organic manure and inorganic fertilizer on the yield and yield attributes of Boro Rice (Oryza sativa L.). The experiment consisted of 8 treatments, T0: Control, T1: 100% N100P15K45S20 (Recommended dose), T2: 50% NPKS + 5 t cowdung ha-1, T3: 70% NPKS + 3 t cowdung ha-1, T4: 50% NPKS + 4 t poultry manure ha-1, T5: 70% NPKS + 2.4 t poultry manure ha-1, T6: 50% NPKS + 5 t vermicompost ha-1and T7: 70% NPKS + 3 t vermicompost ha-1. At 30, 50, 70, 90 DAT and at harvest stage the tallest plant (24.18, 31.34, 44.67, 67.05 and 89.00 cm) and the greatest number of total tiller per hill (5.43, 11.64, 21.01 and 17.90) at same DAT was recorded from T5 and the lowest was observed from T0 in every aspect. The maximum number of effective tillers per hill (13.52), the longest panicle (24.59 cm), maximum number of total grain per plant (97.45), the highest weight of 1000 seeds (21.80 g), the maximum grain yield (7.30 t ha-1) and straw yield (7.64 t ha-1) was recorded from T5 treatment whereas the lowest number of effective tillers per hill (6.07) , the shortest panicle (16.45 cm) , the minimum total grain per plant (69.13) , the lowest weight of 1000 seeds (16.73 g), the lowest grain yield (2.06 t ha-1) and straw yield (4.63 t ha-1) was observed from T0 treatment. Although the highest biological yield was recorded from T5 treatment but statistically similar result were found from T3, T4 and T7 treatments. The highest harvest index also recorded for T5 treatment. It was obvious that yield of rice can be increased substantially with the judicious application of organic manure with chemical fertilizer.

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during winter (Rabi) season of 2013-14 to evaluate the effect of integrated use of organic and inorganic fertilizers on the growth, yield and nitrogen (N) uptake of wheat. There were six treatments such as T0 (control), T1 [STB-CF (HYG)], T2 [STB-CF (HYG) + CD (5 t/ha)], T3 [STB-CF (HYG) +PM (3 t/ha)], T4 [STB-CF (HYG) COM (5 t/ha)] and T5 [FP (Farmers’ practice)]. The experiment was laid out in a Randomized Complete Block Design with four replications. Soil test based nitrogen, phosphorus, potassium, sulphur, zinc and boron were used @ 100, 20, 60, 10, 3 and 2 kg ha-1, respectively. The integrated use of organic and inorganic fertilizers significantly increased the yield attributes as well as grain and straw yields of wheat. The treatment T3 [STB-CF (HYG) + PM (3 tha-1)] produced the highest grain yield of 3554 kg ha-1 (69.67% increase over control) and straw yield of 3635 kg ha-1 (62.83% increase over control). The lowest grain yield (2094 kg ha-1) and straw yield (2232 kg ha-1) were found in control treatment. The N content and uptake by wheat were also markedly influenced by combined use of organic and inorganic fertilizers and the treatment T3 demonstrated superior performance to other treatments. So, the applications of fertilizers in combination with poultry manure @ 3 t ha-1 can be used for the successful cultivation of wheat in Old Brahmaputra Floodplain soil. Progressive Agriculture 27 (2): 149-153, 2016

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.

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.

High Yielding Varieties

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.

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during November 2011 to March 2012 to evaluate the effect of integrated use of manures and fertilizers on the growth, yield and nutrient uptake by wheat. There were six treatments such as T0 (Control), T1 [STB-CF (HYG)], T2 [CD + STB-CF (HYG)], T3 [PM + STB-CF (HYG)], T4 [COM + STB-CF (COM)] and T5 [FP (Farmers’ practice)]. The experiment was laid out in a Randomized Complete Block Design with four replications. The integrated use of manures and fertilizers significantly influenced the yield attributes as well as grain and straw yields of wheat. The treatment T1 [STB-CF (HYG)] produced the tallest plant of 90.17 cm which was identical with T3 [PM + STB-CF (HYG)] and the lowest value was found in control. The 1000-grain weight followed the similar pattern but the tillers hill-1, spike length and spikelets spike-1 did not follow any definite trend. The treatment T3 [PM + STB-CF (HYG)] produced the highest grain yield of 4362 kg ha-1 (90.4% increase over control) and straw yield of 5492 kg ha-1 (84.79% increase over control). The lowest grain yield (2291 kg ha-1) and straw yield (2972 kg ha-1) were found in T0 (Control). The NPKS uptake by wheat was markedly influenced by combined use of manures and fertilizers and the treatment T3 demonstrated superior performance to other treatments. So the treatment T3 comprising poultry manure in combination with chemical fertilizers on IPNS basis was found to be the best combination of manures and fertilizers for obtaining the maximum yield and quality of wheat at BAU farm.

A field experiment was conducted at the experimental field of the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during November 2013 to March 2014. Four soybean genotypes i.e BU Soybean1, BD2329, BD2331, AGS313 and a check variety BARI Soybean 6 were used to evaluate their variations in morphological characters and yield attributes. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The highest LAI (4.4) was found in genotype AGS313 and the smallest was found in BU Soyabean1. The highest pod size of 625 mg pod-1 was found in AGS313 while the lowest of 340 mg pod-1 was observed in BU Soybean1. Although BU Soyabean1 had smaller seed size but it had higher number of pods plant-1 (32.1) compared to other genotypes. The maximum 100-seed weight was recorded in AGS313 (16.34 g) and the minimum was obtained from the genotype BU Soybean1 (11.0 g). AGS313 genotype contributed to the highest grain yield of 4.29 tha-1, while BU Soyabean1 stood second position contributing 2.65 tha-1. Results also indicated that not only seed size but also number of pods plant-1 contributed to grain yield. Again there were highly significant differences among genotypes for all the characters.J.
