Nitrogen is one of the main inputs of oat cultivation and its efficient management is a basic for harvesting the maximum potentiality of the crop. An investigation was conducted at field laboratory of Agrotechnology Discipline, Khulna University, Bangladesh to find out the effect of nitrogen fertilizer on growth, yield and yield contributing characters of oat during 2017-2018. The experiment was designed in randomized complete block with seven N rates (0, 30, 45, 60, 75, 90 and 105 kg ha-1) in triplicate run. Application of N nitrogen significantly increased the growth and yield of oat. The results showed that 105 kg ha-1 N was supreme in all growth parameters and straw yield but 90 kg ha-1 N was better for main yield parameters and grain yield. The maximum plant height (101.27 cm), leaf number (11.90), tillers plant-1 (9.93), plant density (41.33 m-2) and straw yield (4.70 tha-1) were recorded with  105 kg ha-1 N application, whereas the highest grain yield (1.76 t ha-1) was found with 90 kg ha-1 N. From the results of the present research, it may be concluded that application of 90 kg N ha-1 could be used for oat production in soils of AEZ 13, Bangladesh. Bangladesh Agron.

Effect of concentrate organic manure (wellgrow grain and wellgrow soil) and NPK improved the growth and yield of wheat. Significant improvement in terms of growth parameters like plant height, tillers, dry matter production and productive tillers with application of 120 : 60 : 60 NPK + 300 kg wellgrow soil/ha and at par with application of 120 : 60 : 60 NPK + 300 kg wellgrow grain/ha, treatment receiving 100% NPK + 300 kg wellgrow soil/ha resulted maximum grain yield (4545 kg /ha). Treatment of 100% NPK + 300 kg wellgrow grain/ha maintained higher straw yield (5715 kg/ha) and test weight (44.10 g) due to application of 100 % NPK along with 200 kg wellgrow soil/ha whereas it was at par with application of 75 and 100% NPK with both levels of wellgrow formulation.

SUMMARYExperiments with spring barley in 1975–7 tested fungicides applied to control powdery mildew (tridemorph) or brown rust (benodanil) in factorial combination with six amounts of fertilizer N, applied either to the seed bed soon after sowing, as a later top dressing or half at each time.Powdery mildew was the principal leaf disease in all three years. It tended to be increased by increments of N and by applying the N late but much less consistently in the first two years, when soils were very dry for much of the growing period, than in 1977 when amounts of rain were much closer to the long-term mean. Tridemorph significantly increased the number of ears in 1975, mean number of grains per ear in 1976 and 1000-grain weight in all three years; it gave net increases in grain yield of 0·55, 0·68 and 0·41 t/ha, respectively, in 1975–7. Yield response to increasing amounts of applied N was greatly increased where mildew had been controlled by the use of tridemorph, and was better where the N had been divided into two dressings than where it had been applied as a single dose. In 1975 and 1977 the biggest responses to tridemorph were obtained with late N but in 1976 yield was increased most by tridemorph where the N had been applied to the seed bed.Analyses of samples taken in 1977 showed no significant effect of tridemorph sprays on concentrations of either N, P or K in the green crop. By contrast, analyses of grain samples in 1976 and 1977 showed that amounts of N in grain (mg N/grain) were affected by amounts of applied N and by tridemorph, and that there were interactions between these two factors. Concentrations of N in the grain (% D.M.) were also determined by the effects which these factors had on grain size. At small N rates tridemorph mostly increased grain size so that N concentrations were decreased by the fungicide. At large N rates increases in grain size where tridemorph had been applied were accompanied by increases in the N content of the grain (mg N/grain) so that N concentrations were either unaffected (1976) or were increased (1977) by the fungicide. With 90 kg/ha of applied N the fungicide increased the amount of N/ha removed in grain by over 21 % in each year. The apparent recoveries of N in these plots were increased from 66 to 81 % and from 87 to 105%, respectively, in the two years. Tridemorph had no significant effect on concentrations of P or K in the harvested grain but increased average amounts of these nutrients removed in the grain by 17 and 14%, respectively, in 1976 and by 14 and 7% respectively, in 1977.Examination of black and white, infra-red aerial photographs of the experiments showed that, in each year, the brightness of individual plot images was significantly correlated with grain yield.Complex designs without division into blocks are especially vulnerable to positional variation. Alternative methods of adjusting for such positional variation were compared in analyses of grain yields. The potential improvements in precision which might be achieved by the appropriate use of such analyses, and the difficulties of ensuring that unacceptable subjectivity and bias are not thereby introduced into the analyses, are discussed.

Straw Ash

A pot experiment was conducted in the net house to evaluate the growth and yield response of two vegetables as influenced by the application of maize straw ash in mixed soil. The vegetables were White Malabar Spinach (Basella alba L.) and Red Malabar Spinach (Basella rubra L.). The mixing of acid soil with calcareous soil was done at 3:1 ratio. Maize straw ash was applied at different rates such as T2 (1 ton/ha), T3 (2 ton/ha) and T4 (3 ton/ha). The control as T1 received no amendment. Plant height, base diameter and fresh weight of the Spinach were significantly (p ≤ 0.05) increased from the control treatment. All the studied growth parameters attained significant improvement for the T3 (2 ton/ha) among all treatments in both the varieties of Malabar. Nutrient contents (N, P, K, S, Ca, Mg, Fe, Mn, Zn and Cu) of Red Malabar Spinach increased significantly for ash treatments and the highest increment of the N, P, S, Na, Ca, Mg and Zn were obtained by the T3 treatment. For White Malabar Spinach, all the nutrients were increased significantly for T3 compared to the control, except for the N (insignificant increase) and Ca (decrease). The application of maize straw ash at the rate of 2 ton/ha (T3) increased plant growth, yield and nutrient contents in both the varieties of Malabar which might be attributed that, the maize straw ash can be considered as an amendment for the improvement of crop growth that may also have lasting effect on soil quality as well as economic and eco-friendly.

The experiment was conducted in the farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from August to December 2012 to study the effect of various combinations of organic manure and inorganic fertilizer on the growth, yield, chlorophyll and nutrient content of rice var. BRRI dhan33. The treatment consists of T1: 100% Inorganic fertilizer (Recommended dose) + 5 ton poultry manure (PM) /ha , T2: 75 % N of recommended dose + 5 ton PM /ha, T3: 50 % N of recommended dose + 5 ton PM /ha, T4: 25 % N of recommended dose + 5 ton PM /ha, T5: 75 % S of recommended dose + 5 ton PM /ha, T6: 50 % S of recommended dose + 5 ton PM /ha, T7: 25 % S of recommended dose + 5 ton PM /ha, T8: 100% Inorganic fertilizer and T9: 5 ton PM /ha. Significant variation was found in growth and yield parameters as well as in chlorophyll content and nutrient content of aman rice. The most of the growth parameters ( plant height, leaf length and diameter, leaf number and total tiller plant-1) results were found better in 100% Inorganic fertilizer + 5 ton PM ha-1 which was statistically similar with 75 % of recommended dose of S + 5 ton PM ha-1, 75 % of recommended dose of N + 5 ton PM ha-1and followed by 50 % of recommended dose of S + 5 ton PM ha-1,respectively while the lowest from 5 ton/ha PM treatment. On the other hand, significantly higher chlorophyll “a”, “b” and total chlorophyll content were recorded in 100% Inorganic fertilizer + 5 ton PM ha-1and it was closely followed by 75 % of recommended dose of N + 5 ton PM ha-1 and lowest in 5 ton PM ha-1. Number of effective tillers plant-1, panicle length, number of rachis plant-1, filled grain plant-1 and fresh weight of plant were highest in 100% Inorganic fertilizer + 5 ton PM /ha and it was either statistically similar or closely followed by 75 % of recommended dose of S + 5 ton PM ha-1. Higher grain yield (4.18 t ha-1) was recorded in T1 which was statistically similar with T5 (4.13 t ha-1) whereas lowest grain yield (3.67 t ha-1) was from sole PM. Similarly, N content in grain and N, K content in straw were also showed similar trend. S content in grain and P, S content in straw were higher in 75 % of recommended dose of S + 5 ton PM /ha compared to other fertilizer treatments. Lowest N and S content in grain and N, P, K, S content in straw were found from the treatment using poultry manure only.Bangladesh Agron. J. 2015, 18(1): 99-111

Boro Rice

An experiment was conducted to find out the effect of variety, date of transplanting and its interaction on the growth and yield performance of high yielding Boro rice. The experiment comprised five varieties viz., BRRI dhan28, BRRI dhan58, BRRI dhan67, BRRI dhan69, BRRI dhan74 and five dates of transplanting viz., 15 December, 30 December, 15 January, 30 January and 15 February. The experiment was laid out in a randomized complete block design with three replications. Results revealed that growth parameters, crop characters, yield components and yield were significantly influenced by variety, date of transplanting and their interactions. The leaf area index (LAI) and dry matter production hill-1 were highest in BRRI dhan69 when transplanted on 15 January whereas the lowest value was found in BRRI dhan28 when transplanted on 15 February. The number of effective tillers hill-1 (11.80), number of grains panicle-1 (130.90), 1000-grain weight (22.07 g), grain yield (4.96 t ha-1) and straw yield (6.64 t ha-1) were highest in BRRI dhan69 whereas corresponding lowest values were recorded in BRRI dhan28. The crop transplanted on 15 January produced the highest number of effective tillers hill-1 (12.81), highest number of grains panicle-1 (131.20), heaviest 1000-grain weight (21.93 g), highest grain yield (5.36 t ha-1) and highest straw yield (7.71 t ha-1). In case of interaction, the highest grain (5.90 t ha-1) and straw yields (7.87 t ha-1) were recorded in BRRI dhan69 transplanted on 15 January whereas the lowest grain and straw yields were recorded in BRRI dhan28 transplanted on 15 February. Therefore, it can be concluded that BRRI dhan69 along with 15 January transplanting appears as the promising combination in terms of grain and straw yields.

AbstractDeficiency of sulfur (S) is increasingly being reported in the soils of Ethiopia. While some studies have shown significant response of barley to S application, information on the response of barley to S application is conspicuously lacking. The average yield of barley in Ethiopia is lower compared to the world and potential yield. It is mostly constrained by the depletion of soil fertility, caused by imbalanced fertilization, limited application of organic manure, intensive cropping. A field experiment was conducted at two locations for three consecutive years (2014–2016) to determine the effect of S on growth, yield components, and yield of food barley. An experiment consisting of six levels S (0, 10, 20,30,40, and 50 kg ha−1) laid out in RCB design with three replications. The study results revealed that growth and yield components of barley were not affected by various levels of S. In the case of barley grain and straw yield was significantly affected by S levels compared to control treatment. Application of S at 20 kg ha−1 increased grain and straw yield of food barley by 16.8 and 20.2% compared to control, respectively. Application of 20 kg S ha−1 produced the highest marginal rate of return (MMR) (3493.2%). The present result revealed that barley yield has been improved by the application of S fertilizer. Therefore, the application of 20 kg S ha−1 is initiate to be the further most economically feasible treatment for food barley production in the Basona woreba district.

Flooding can reduce corn growth and yield, but nitrogen (N) management practices may alter the degree to which plants are negatively impacted. Damage caused by flooded conditions may also affect the utilization of a post-flood N application to increase yield. The objectives of this study were to evaluate how pre-plant and pre-plant plus post-flood N applications contribute to corn growth and yield following flood conditions and to quantify the partial return of employing different N management strategies in the event of a flood. A field study was conducted in Ohio using four flood durations (FD; 0, 2, 4, or 6 days initiated at V4 to V5) and three N management practices (0 kg N ha−1, 134 kg N ha−1 applied pre-plant, and 134 pre-plant + 67 kg N ha−1 applied post-flooding). Application of 134 kg N ha−1 increased yield compared to 0 kg N ha−1 by 65%, 68%, 43% and 16% for 0 d, 2 d, 4 d, and 6 d FD, respectively; the application of 134 + 67 kg N ha−1 increased grain yield compared to 134 kg N ha−1 by 7%, 27%, 70%, or 55% for 0 d, 2 d, 4 d, or 6 d FD, respectively. Partial return analysis produced similar results to those for grain yield. Results suggest that in regions prone to early-season flooding, additional N applied post-flood can improve yield and partial return compared to the application of pre-plant alone at a lower rate or no N. Results indicate that total soil nitrate-N levels two weeks after flood initiation may serve as a good predictor of yield.

ABSTRACT The objective of this work was to evaluate the effect of plant densities and sidedressed nitrogen (N) rates on nutrition and productive performance of the common bean cultivars IPR 139 and Pérola. For each cultivar, a randomized complete block experimental design was used in a split-plot arrangement, with three replicates. Plots consisted of three plant densities (5, 7, and 9 plants ha-1) and subplots of five N rates (0, 30, 60, 120, and 180 kg ha-1). Aboveground dry matter, leaf macro- and micronutrient concentrations, yield components, grain yield, and protein concentration in grains were evaluated. Lower plant densities (5 and 7 plants m-1) increased aboveground dry matter production and the number of pods per plant and did not reduce grain yield. In the absence of N fertilization, reduction of plant density decreased N concentration in common bean leaves. Nitrogen fertilization linearly increased dry matter and leaf N concentration, mainly at lower plant densities. Regardless of plant density, the N supply linearly increased grain yield of cultivars IPR 139 and Pérola by 17.3 and 52.2%, respectively.
