The interactive effects of lime and phosphorus on maize growth in an acid soil were investigated in a greenhouse experiment. A completely randomized design with 12 treatments consisting of four lime levels, 0, 2, 10, and 20 t ha−1, in a factorial combination with three phosphorus rates, 0, 30, and 100 kg ha−1, was used. Maize was grown in pots for six weeks and its heights and dry matter yield were determined and soils were analyzed for available P and exchangeable acidity. Liming significantly reduced the exchangeable acidity in the soils. The effect of lime on available P was not significant but available P increased with increasing P rates. There was a significant effect of lime, P, and P by lime interactions on plant heights and dry matter. Without lime application, dry matter increased with increasing P rates but, with lime, dry mattes increased from 0 to 30 kg P ha−1but declined from 30 to 100 kg P ha−1. The highest dry matter yield (13.8 g pot−1) was obtained with a combined 2 t ha−1of lime with 30 kg P ha−1suggesting that lime application at low rates combined with moderate amounts of P would be appropriate in this soil.

The effects of substrates formulated with different proportions of decomposed buriti stem (Mauritia flexuosa) and the application of nitrogen fertilizer rates in the production of cagaita (Eugenia dysenterica DC.) seedlings were investigated in this study. The treatments were arranged in a completely randomized design, in a 3 × 5 factorial: three substrates formulated from different proportions of decomposed buriti stem (0, 25 and 50%) with a clay loam soil (Oxisol), and five N fertilizer rates (0; 100; 200; 300 and 400 mg dm-3), with four replicates. At 60 days after emergence, the plant height, stem diameter, leaf area, root length, dry matter accumulation of shoots, roots, and total, shoot:root dry matter ratio (SRR), height:diameter ratio (HDR), and Dickson quality index (DQI) were measured. The substrate containing soil and decomposed buriti stem in the proportion of 3:1 (v:v), in association with the application of N rates from 167 to 190 mg dm-3 is recommended for the production of cagaita seedlings, resulting in positive effects on plant growth and development as reported by higher PH, SRR, and HDR. The application of 154 mg dm-3 of N resulted in higher DQI of the cagaita seedlings.

Nursery experiment was conducted at Haru Agricultural Research Sub Center (HARSC) of Jimma Agricultural Research Center, Western Ethiopia, to investigate dry matter yield and its nutrient uptake of Arabica coffee seedlings under different lime and coffee husk compost rates and establish optimum combination of theseagricul tural inputs that produce seedlings with better dry matter yield for field planting. The experiment was laid out in a factorial experiment arranged in randomized complete block design with three replications. The treatments included four levels of lime (0, 1.6, 3.2 and 4.8 t ha-1) and coffee husk compost (0, 5, 10 and 15 t ha-1). Nutrient uptake and dry matter yield data of coffee seedlings were collected and subjected to analysis of variance using SAS package and treatment means were compared at 0.05 probability using Duncan’s Multiple Range Test. The results revealed that lime and coffee husk compost rates significantly (P< 0.01) affected NPK uptake and total dry matter yield of coffee seedlings. The highest NPK uptake and total dry matter yield of coffee seedling were obtained from the application of 15 t.ha-1 coffee husk compost and combined lime and coffee husk compost at the modest levels of 3.2 t.ha-1 lime and 10 t.ha-1 coffee husk compost with a nonsignificant variation. From the study, it can be concluded that application of 15 t.ha-1 coffeehusk compost or combining 10 t.ha-1 of coffee husk compost and 3.2 t.ha-1 of agricultural lime could be a promising alternative amendment for acid soil management and production of vigorous coffee seedlings with high nutrient uptake and high dry matter yield in HARSC areas.

High biogas yields are expected from sugar beet because of its high root yield. But it has not been analysed yet, which varieties are best suited to reach the highest biogas yield. The study thus aimed at identifying a parameter to estimate the biogas yield of sugar beet. To get a broad variation of yields and beet qualities, field trials were conducted from 2008 to 2011 at 2 sites (Göttingen and Regensburg, Germany) with different sugar beet varieties and fodder beet. Different N application rates were included and furthermore, autumn sown beets (winter beet). Dry matter composition was analyzed, biogas yield and methane concentration were determined in batch experiments. Sugar beet reached root dry matter yields of more than 20tha–1 and thereby exceeded fodder beet. Moderate N application increased root dry matter yield, whereas higher N rates only enhanced the leaf dry matter yield. But most likely, leaves will not be considered for fermentation because of their low concentration of dry matter and organic dry matter. Winter beet reached total dry matter yields of 12tha–1, but dry matter was not as easily digestible as that of spring sown beets. Biogas yield showed a close linear relation to the root dry matter and the sugar yield as well. Sugar beet varieties can therefore be assessed for anaerobic digestion by their sugar yield. As sugar yield is already the main target, breeding for biogas beets will not be substantially different from that for beets used for sugar manufacture.

Wheat grain yields, dry matter production and yield components were measured in a field experiment in north-eastern Victoria over 5 seasons where lime application and deep ripping had been carried out. The soil at the site was strongly acid (pHw 5.2 at 0-1 0 cm) and had a dense hardpan at 7.5- 17.5 cm depth. Grain yields (control yields 1981-85: 1.34, 0.25, 1.64, 2.36, 2.09 t ha-1) were increased each year by both lime (31-103% range) and deep ripping (11- 41% range), but the application of some lime was necessary to obtain benefit from deep ripping. The increased grain yield was mainly due to more heads per metre of row, although head size and grain weight were also increased by lime treatment. Lime increased the dry matter yield of roots and decreased the top to root dry matter ratio. Deep ripping increased the dry matter yield of roots at depth and also reduced root distortion where the hardpan had been shattered. In a drought season, deep ripping increased grain weight. Root disease was accentuated at the higher rates of lime.

Animal manure is applied to the soil as a nutrient source, especially of nitrogen, to plants. However, manure application rates can be reduced with the use of N fertilizer in topdressing. The aim of this study was to evaluate crop responses to different application rates of animal manure sources, used alone and supplemented with mineral N topdressing, in a no-tillage system. The study was carried out from 2005 to 2008 on a Hapludalf soil. The treatments consisted of rates of 10, 20 and 30 m³ ha-1 of pig slurry (PS), and of 1 and 2 t ha-1 of turkey manure (TM), applied alone and supplemented with topdressed N fertilizer (TNF), as well as two controls, mineral fertilization (NPK) and one control without fertilizer application. Grain yield in common bean and maize, and dry matter yield and nutrient accumulation in common bean, maize and black oat crops were evaluated. Nitrogen application in topdressing in maize and common bean, especially when PS was used at rates of 20 and 30 m³ ha-1, and TM, at 2 t ha-1, proved effective in increasing the crop grain yields, showing the viability of the combined use of organic and industrialized mineral sources. Nitrogen accumulation in maize and common bean tissues was the indicator most strongly related to grain yield, in contrast with the apparent nutrient recovery, which was not related to the N, P and K quantities applied in the organic sources. No clear residual effect of N topdressing of maize and common bean was observed on the dry matter yield of black oat grown in succession to the main crops with PS and TM applications.

Silicon Accumulation

The beneficial effects of silicon (Si) fertilization have been observed for several plant species, especially when submitted to stress, either biotic or abiotic. Among the possible reasons for the greater adaptability and resistance of brachiaria grass in areas of low fertility soils in Brazilian savanna, stands its capacity of absorbing and accumulating Si in aerial parts. To evaluate the effect of Si on dry matter yield of Brachiaria decumbens Stapf and Brachiaria brizantha Hochst, grown under two soil moisture regimes, a trial was set up in a completely randomized design factorial scheme (5 × 2 × 2), with five Si rates: (0; 242; 484; 968 and 1,452 kg ha-1), two soil water tensions (60% and 80% of field capacity) and the two brachiaria species. The experiment was installed in a greenhouse, using one of the most representative soils in the region under cerrado, Typic Haplustox. Both brachiaria species can be considered Si-accumulating plants, since they present high Si contents in their aerial parts. Application of Si to the soil increased the contents of this element in both grass species but did not change their tolerance to water deficit, and did not affect dry matter yield.

A field experiment was carried out in the paddy field of Charfession Govt. College, Bhola, Bangladesh during rabi season 2017 to evaluate growth, biomass production and nitrogen accumulation in mungbean plants. The size of the plot was 60 cm x 45 cm. The distance between row to row and plant to plant was 30 cm and 10 cm, respectively. Eight plants were raised per plot. Seven treatments were P0K0 (Control), P5K6, P5K12, P5K18, P10K6, P10K12 and P10K18 kg ha-1. Forty day old plants were harvestedas root, stem and leaf. The highest plant height (17.2 cm) and number of leaves (14.3 no. plant-1) were recorded in P5K12 kg ha-1 treatment at harvest. The maximum concentration of nitrogen in root, stem and leaf were 1.59, 2.51 and 3.82% in the treatments of P5K12, P5K12 and P5K18 kg ha-1, respectively. The highest amount of dry matter yield 1.88 g plant-1 was observed in P5K12 kg ha-1 treatment. The overall better dose was P5K12 kg ha-1. Thus, a considerable amount of nitrogen and organic matter might be added to paddy fields through the cultivation of mungbean in the coastal region of Bangladesh. Int. J. Agril. Res.
