Malt Barley

A field experiment was conducted in north Gondar to investigate the response of malt barley varieties to different inter-row spacing under contrasted environment. The experiment was laid out using randomized complete block design with three replications. The treatments were three different inter-row spacing (i.e., 20, 25, and 30 cm), six malt barley varieties (i.e., Holker, HB1963, Sabine, Ibone174/03, EH1847, and Freygebse), and two locations (Miligebsa and Kino). The result sowed that days to 50% heading, days to 90% physiological maturity, plant height, spike length, and number of kernels per spike were significantly ( p < 0.01 ) affected by the main effect of location and varieties. Similarly, effective tiller number, biomass yield, grain yield, and straw yield were significantly ( p < 0.01 ) influenced by the main effect of variety, inter-row spacing, and location. Important interaction was also observed between varieties × inter-row spacing × location on days to 50% heading, spike length, biomass yield, grain yield, and straw yield. Location × variety interaction significantly influences the days to 90% physiological maturity and effective tiller number. Similar significant ( p < 0.05 ) trend was also observed between varieties with inter-row spacing on effective tiller number and thousand kernel weight even at p < 0.01 level of significance. It was found that optimization of row spacing was found to be influenced by location and varietal difference. Hence, on the basis of the result, it can be inferred that 25 cm row spacing combined with the varieties “HB1963,” “Hollker,” and “Sabine” was optimum for maximum yielding potential under potential environment (Miligebsa).

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

To evaluate the effect of Zinc fertilizer on performance of wheat cv. BARI gom30, an experiment was carried out at Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, from November 2015 to March 2016. The experiment comprised four levels of Zinc (Zn) viz., 0, 1.5, 2 and 2.5 kg/ha. The experiment was laid out in a randomized complete block design with three replications. Application of Zinc (Zn) plant height, number of total tillers/plant, number of effective tillers/plant, spike length, number of fertile spikelets/spike numbers of sterile spikelets/spike number of grains/ spike, grain yield and straw yield were found significant. But there was no significant effect of the treatment on 1000-grain weight. The highest number of total tiller/plant (4.42), number of effective tillers/plant (3.92), number of grains/spike (47.70), 1000-grain weight (47.73 g), grain yield (5.06 t/ha), straw yield (6.21 t/ha) was obtained from 2 kg Zn/ha. The highest plant height (94.08 cm), spike length (9.92 cm), number of fertile spikelets/spike (19.59) and sterile spikelets/spike (3.22) and harvest index (46.16%) were recorded at 0 kg Zn/ha respectively. The control treatment indicated the lowest value for the yield attributing characters except the number of sterile spikelets/spike. Grain yield was found to be significantly and positively correlated with number of grains/spike and straw yield. It is recommended that application of 2 kg Zn/ha is the best for maximum yield of BARI gom30.

Production of mungbean has been increasing in Ethiopia because of its high importance as a source of protein and foreign exchange earnings. Determination of appropriate plant density for the varieties of mungbean can increase its productivity. Therefore, an experiment was conducted to determine the effect of inter and intra row spacing on growth, yield components and yield of mung bean varieties under irrigation. The treatments consisted of factorial combinations of three inter row spacing (30, 40, and 50 cm), three-intra row spacing (5, 10 and 15 cm) and two mungbean varieties (N-26 and MH-97) laid out in randomized complete block design with three Replications. The main effect of varieties, inter row spacing and intra row spacing was highly significant and significant on plant height, secondary branch and where the longest plant height (41.71 cm) was for variety MH-97 and from 5 cm intra row spacing, respectively and maximum number of secondary branch was recorded for variety MH-97 (8.91) and from 15cm intra row and 50cm inter row spacing, respectively.  The interaction effect of the variety, inter and intra row spacing was highly significant on number of primary branch per plant, number of pod per plant and crop stand count percentage where the highest number of primary branches (7.00) was recorded from variety MH-97 at 50 cm inter row spacing and highest number pods per plant (30.15) were recorded for variety MH-97 at 40 cm inter row and (31.34) at 15cm intra row spacing. Where the highest crop stand count at harvest were recorded from variety MH-97  (97.00%) at 40 cm inter row spacing .The main effect of inter row spacing and intra row spacing were highly significant and significant on above ground dry biomass and the highest above ground dry biomass at inter row spacing of 30 cm ( 5968.8 kg ha-1) and intra row spacing 5cm 6145.9 kg ha-1).The main effect of variety, inter-row and intra-row spacing were highly significant on harvest index and grain yield where the highest harvest index was from variety MH-97 (20.91%), inter row spacing of 40 cm which give (21.18%) and intra row spacing 10 cm which give  (20.30%) and the highest grain yield from Variety MH-97 (1117.94 kg ha-1), inter row spacing 40 cm (1213.75 kg ha-1) and intra row spacing 10 cm which give (1151.67 kg ha-1) However, this tentative generalization based one season at one location requires further studies over years and locations to give a valid recommendation.

Tef (Eragrostis tef (Zucc.) Trotter] is one of the most important cereal crops and predominant staple food in Ethiopia. However, its productivity is constrained by a number of problems, lack of site-specific fertilizer recommendation and high yielding varieties are crucial in the study area. Hence, a field experiment was conducted during 2020 main cropping season to identify most productive variety and determine most economically feasible blended NPSZnB fertilizer rate at Farmers Training Center in Ucha Kebele, Haro Limmu district. The experiment included five different NPSZnB fertilizer rates (0, 50,100, 150 and 200 kg ha-1) and three Tef varieties (Negus, Tesfa and local). The treatments were factorially combined and laid out in randomized complete block design with three replications. Days to 50% heading, days to 90% physiological maturity, plant height and thousand seed weight of Tef were significantly influenced by main effect of varieties, blended NPSZnB fertilizer rates and their interactions. Panicle length, dry biomass yield, lodging index, grain yield, straw yield and harvest index of Tef were significantly (P<0.001) affected by main effect of blended NPSZnB fertilizer rates and the interactions of the two factors, while the panicle length, dry biomass yield, lodging index and grain yield, straw yield and harvest index of Tef were significantly (P<0.01; 0.05) affected by main effect of varieties respectively. Highest (118.20 cm) plant height, dry biomass yield (9. 64 t ha-1), straw yield (7.02 t ha-1), grain yield (2.62 t ha-1), thousand seed weight (0.42 t ha-1) and harvest index (27.1%) were recorded from Tesfa variety with 150 kg NPSZnB ha-1 blended fertilizer rate. Similarly, the highest (7.42 t ha-1), straw yield, dry biomass yield (9.76 t ha-1), grain yield (2.34 t ha-1), thousand seed weight (0.4 g) and panicle length (44.20 cm)   were recorded from Tesfa variety with application of 200 kg NPSZnB ha-1 blended fertilizer rate and the highest total number of tillers (10.1) and effective number of tillers (9.7) were recorded with 150 kg NPSZnB ha-1 blended fertilizer rate. Grain yield of Tef showed increment by 91.22 % with the application of 150 kg NPSZnB ha-1 with Tesfa variety over the control. Highest net profit of ETB 83229.4 with marginal rate of return of 1553.71% was recorded from Tesfa variety with application of 150 kg NPSZnB ha-1 blended fertilizer rate. Therefore, farmers of the study area should use Tesfa variety based on the grain yield and net profitability benefits achieved with 150 kg NPSZnB ha-1 fertilizer rate to enhance Tef production and productivity. However, this experiment was conducted only for a single season and site, further study has to be done under different seasons and agro-ecologies to make more reliable recommendations.

Study was initiated with the objectives to identify high yielder malt barley varieties. The trial has been conducted during 2014 main season and laid out on randomized complete block design with three replications. Analysis of variance was computed using SAS, 2002. At Dabat, result showed that highly significant difference among the varieties (p < 0.05) for all agronomic traits. At Debark and Wegera the analysis of variance indicated that highly significant to a significant difference among varieties  at p < 0.05 for days to heading, days to maturity, plant height, spike length, thousand seed weight and grain yield, and seed per spike. The combined analysis of variance showed that highly significant difference among varieties for days to heading, days to maturity, plant height, spike length, and grain yield. The location also contributed the significant effect for all yield components except biomass and grain yield. The interaction of location by genotype showed the highly significant difference on days to maturity and plant height. The average heading days ranged from 70-81 and the average maturity days were ranged from 127-136. Among the tested varieties, IBON-174/03 and SABINI exhibited highest grain yield. The overall combined analysis indicated that IBON-174/03 and SABINI were high yielder and well adapted at the tested sites. Therefore those varieties are recommended for production in the testes sites, and similar agro-ecologies.

Tef (Eragrostis tef (Zucc.) Trotter] plays a crucial role in achieving food and nutritional security in Ethiopia being predominant staple food. Lack of high yielding varieties suitable to the area and inadequate site-specific blended fertilizers are the major constraints to higher tef productivity. Hence, a field experiment was conducted during 2020 main cropping season to identify high yielding variety and determine economically feasible blended NPSZnB fertilizer rate at Farmers Training Center in Ucha Kebele, Haro Limmu district.

Due to increasing scarcity of fresh water, use of unconventional water source (e.g., wastewater) in irrigation has now become important. However, inclusive information on the effects of wastewater on crop production and soil health is necessary for such intervention. This study was designed to evaluate these effects by demonstrating the contribution of municipal wastewater (hereafter called wastewater) on yield and nutrient requirement of wheat (<i>Triticum aestivum</i> L.) cv Shatabdi. Five irrigation treatments - I1, I2, I3, I4 and I5  were tested in a Randomized Complete Block Design (RCBD) with three replications during November-March of 2007-2008, 2008-2009, 2009-2010 at the experimental field of the Bangladesh Agricultural University,  Mymensingh. The treatments I2-I5 consisted of blended wastewater and I1 of fresh water (control). The ratio of wastewater to total irrigation water was 0.25, 0.50, 0.75 and 1.0 in I2, I3, I4 and I5, respectively. Wheat was cultivated with three irrigations and recommended doses of fertilizer in three consecutive years. Wastewater contained nitrogen (N), phosphorus (P) and potassium (K) @ 17.5, 3.7 and 10.3 mg/L, respectively, and irrigation by raw wastewater (I5) contributed 19.1, 15.1 and 21.7% of the recommended N, P and K, respectively. Biomass yield increased with increasing fraction of wastewater in irrigation. Grain yield increased for the wastewater fraction of 0.50 - 0.75 in irrigation but decreased when irrigation was applied by raw wastewater. Excess fertilizer (under I5) boosted up growth of wheat, but did not contribute to the grain yield. Number of grains per spike; and grain, straw and biological yields significantly (p = 0.05) increased due to the contribution of wastewater. Wastewater significantly improved grain and biomass production, with the largest value obtained in I4 (4.61 t/ha grain yield and 11.36 t/ha biomass yield).  Raw wastewater in combination with recommended fertilizer doses caused over-fertilization that contributed only in biomass production but not in grain production of wheat and irrigation by wastewater substantially reduced fertilizer requirement of wheat.The Agriculturists 2016; 14(1) 01-14

ABSTRACT The use of inoculants containing plant growth-promoting bacteria is an alternative to increase the efficiency of nitrogen fertilizers. Studies evaluating the effects of inoculation on forage yield, straw yield, and grain yield in dual-purpose wheat cultivars are scarce. This study aimed to evaluate the forage yield and grain yield in dual-purpose wheat inoculated with Azospirillum brasilense and fertilized with increasing nitrogen rates during two agricultural years (2016-2017) under cutting management. The trial was carried out in a completely randomized block design with four replicates, using a 2 x 4 factorial arrangement. The factors were the inoculation (control or A. brasilense) and nitrogen rates (0, 50, 100 and 150 kg ha-1 of N). Forage, grain and straw yield, and number of tillers were evaluated. Forage yield differed between treatments with inoculation and without inoculation, 3952 and 3350 kg DM ha-1, respectively. There was no effect of inoculation on grain yield. The forage and leaf biomass yield, the number of tillers and straw yield increased with inoculation.

Finger millet is a climate compliant crop; its production remains low due to poor establishment methods. A field experiment was conducted during the rainy season of 2018/19 at Dorcas Charare plot in ward 24, Zaka district to investigate the effects of establishment methods on yield and yield parameters of finger millet (Eleusine coracana L. Gaertn). The experiment was laid out in a Randomized Complete Block Design (RCBD) with three treatments namely broadcasting, hand drilling and transplanting replicated three times. Results on grain yield showed that transplanting method had the highest yield of 0.51t/ha whilst drilling and broadcasting scored 0.40t/ha and 0.35t/ha respectively. Transplanting method significantly (p<0.05) influenced higher number of tillers (7.13) per hill followed by drilling (2.40) and lastly broadcasting (2.13). Significant differences (p<0.05) were noted on panicle number with transplanting scoring the highest (8.13) and broadcasting the lowest (3.13). It can be concluded from the study that transplanting method realized a higher panicle number, tiller number and grain yield. Farmers must adopt transplanting as an establishment method in finger millet production.

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
