Crop diversification in saline affected coastal areas is crucial for food security in Bangladesh. A pot experiment was conducted at polythene house at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur-1706 during May to August, 2017 to determine the effect of salt stress on growth and yield performance of foxtail millets. Five foxtail millets genotypes viz. (i) BARI Kaon-1 (check), (ii) BD-878, (iii) BD-897, (iv) BD-891 and (v) BD-881 were tested under three salt stresses viz. (i) control (0 dS/m), (ii) 6 dS/m and (iii) 12 dS/m. Completely randomized design (CRD) with three replications was followed in the study. The growth parameter viz. stem dry matter, leaf dry matter and root dry matter production of foxtail millets genotypes were significantly varied due to salinity stresses. Salinity stresses also significantly influenced yield and yield contributing characteristics of foxtail millets. The genotypes BD-897 and BD-881 produced the higher dry matter, grains per panicle and grain yield per plants under the saline level of 6 dS/m. The higher stress tolerance index of both the genotypes demonstrate that the genotypes BD-897 and BD-881 were more salt tolerant. Bangladesh Agron. J. 2018, 21(1): 51-59

Dwarf Elephant Grass

This research aims was to determine the effect of bokashi dose on plant height, number of tillers, percentage of stems, fresh production, and dry matter production and also to determine the optimum dose of bokashi to obtain the best results on growth and production at the first harvest of dwarf elephant grass. This research was conducted in March 2020 - July 2020 in Sidodadi Asri village, Jati Agung district, South Lampung regency. This research used a Completely Randomized Design (CRD) with 4 levels of treatment, namely P0 (control); P1 (bokashi dosage 30 tons/ha); P2 (bokashi dosage 40 tons/ha); and P3 (bokashi dosage 50 tons/ha). Each experimental treatment unit has plot measuring 2x2 m2. Each trial unit was repeated 3 times, so there were 12 trial units. The data were analyzed by variations analyzed at 5% and or 1% level, after that it was followed by orthogonal polynomial test. The results showed that the dose of bokashi had a significant effect (P<0,05) on plant height, fresh production, and dry production, but had no significant effect (P>0,05) on number of tillers, and percentage of stems. The effect of bokashi fertilizer on plant height was obtained by using the optimum bokashi dose of 36.73 tons/ha and the equation was = 60,13 + 35,38x - 6.62x2 [0 ; 50 ton/Ha] (P<0,01). The optimum dose was not obtained for the number of tillers, percentage of stems, fresh production, and dry production.

ABSTRACT Although the effects of aluminum on the content and accumulation of mineral nutrients in crops have been studied, but nothing is known about its effect on the nutritional efficiency of sugarcane. Therefore, this study aimed to evaluate the effect of aluminum toxicity on nutritional efficiency, nutrient accumulation, and growth of sugarcane seedling. Sugarcane seedlings of the genotype IACSP95-5000, obtained from one-bud mini-cuttings (3 cm), were used in the test. Seedlings were subjected to treatments in a completely randomized design, with eight Al concentrations in the nutrient solution (0, 10, 20, 30, 40, 50, 60, and 70 mg L−1) and three replicates, totaling 24 experimental units. Analyses determined the contents, accumulation, and absorption, transport, and use efficiency of macronutrients, micronutrients, and aluminum, in addition to dry matter production. The results show that Al affected all variables analyzed, with a decrease in the nutritional efficiency of macronutrients and micronutrients and a drastic decrease in the accumulation of macronutrients in the aerial part, which reflected in the decrease in the dry matter of the plants. The root system was the most affected, with a decrease in growth of up to 60%. Aluminum reduced the use efficiency of nutrient in decreasing order: Ca (69%)> N (60%)> K (59%)> Mg (50%)> S (49%)> P (40%). As for micronutrients, the following decreasing order was observed: Fe (73%)> Zn (59%) = Cu (59%)> Mn (25%).

The objective of this work was to evaluate the dry matter production of elephant grass (Pennisetum purpureum) genotypes, managed under intermittent stocking. A completely randomized design was used, with two genotypes and three replicates. The treatments consisted of factorial combinations (2x2x2) of genotypes ('BRS Kurumi' and the clone CNPGL 00‑1‑3), two light interception levels (LI) at the onset of grazing (90 and 95%), and two post‑grazing canopy heights (30 and 50 cm). A total of 24 Holstein x Zebu crossbred heifers were used. The stocking density varied in order to finish the grazing periods in two days. The interval between the defoliation, based on 95% LI, resulted in a higher leaf mass per grazing cycle. The post‑grazing height of 30 cm did not affect the number of grazing cycles but provided a greater herbage accumulation rate. The cultivar BRS Kurumi has higher pasture growth, lower rest period, and greater number of grazing cycles, which results in increased forage production in the growing season.

A study was conducted to determine the growth, nutrient uptake and yield performance of tanier cultivars Blanca del País, Kelly and Morada under intensive management. Tanier plants grown under field conditions were harvested for biomass production about every 30 days during the growing season. At each harvest, plants were separated into various plant parts to determine dry matter accumulation, N, P, K, Ca, Mg and in uptake and yield. Maximum uptake of nutrients was 307, 83, 417, 112, 68 and 1.4 kg/ha of N, P, K, Ca, Mg and Zn, respectively, for cultivar Blanca del País. Nutrient uptake by Kelly was considerably less than for Blanca del País and Morada. Overall, there were no significant differences in total dry matter production between cultivars Blanca del País and Morada whereas Kelly accumulated significantly less dry matter. Maximum yields ranged from 11,316 kg/ha in Kelly to 34,068 kg/ha in Morada.

Studies on nutritional efficiency of phosphorus in conilon coffee plants are important tools to unravel the high limitation that natural low levels of this nutrient in soil impose to these species cultivars. Therefore, this study aimed at evaluating the nutritional efficiency and the response to phosphorus of conilon coffee clones. Plants were managed during 150 days in pots containing 10 dm³ of soil, in greenhouse. A factorial scheme 13 x 2 was used, with three replications, being the factors: 13 clones constituting the clonal cultivar "Vitória Incaper 8142" and two levels of phosphate fertilization (0% and 150% of the P2O5 usualy recommended), in a completely randomized design (CRD). The results indicate a differentiated response of dry matter production and of phosphorus content on each level of phosphate fertilization for the conilon coffee clones and that CV-04, CV-05 and CV-08 clones are nutritionally efficient and responsive to the phosphate fertilization.

O crescimento da agricultura orgânica, associado às mudanças de padrões de consumo e exigência dos consumidores evidencia um aumento da demanda por alimentos livres de resíduos de agrotóxicos e que apresentem menores riscos à saúde e ao meio ambiente. No entanto, por outro lado, a disponibilidade de métodos alternativos ao controle químico de plantas daninhas, entre outros organismos indesejáveis aos cultivos, ainda é um grande desafio. Dessa forma, o objetivo deste trabalho foi avaliar o efeito da solarização sobre o crescimento e desenvolvimento inicial de plantas daninhas, oriundas de propágulos presentes no solo. O experimento foi realizado na Universidade de Cuiabá, entre os dias 18/01/2018 e 22/02/2018. Foi adotado o delineamento inteiramente casualizado com cinco tratamentos e cinco repetições. Os tratamentos testados correspondem a cinco tempos de solarização do solo, sendo esses: testemunha (sem solarização), solarização por 7 dias, 14 dias, 21 dias e 28 dias. Os resultados mostraram que a solarização pode ser aplicada para a supressão de plantas daninhas. Os efeitos são variados e dependem do tempo de solarização e da espécie da planta. A solarização do solo por 14 dias demonstrou redução acima de 90% da produção de massa de matéria seca de Cyperus rotundus e a solarização por 28 dias demonstrou redução de aproximadamente 70% da produção de massa de matéria seca de Chamaesyce hirta. Palavras-chave: Solarização. Cyperus Rotundus. Chamaesyce Hirta. Controle Alternativo.   Abstract The growth of organic agriculture, associated with changes in consumption patterns and consumer’s demand, shows an increase in demand for food free from  residues of pesticides and have lower  risks to health and the environment. But on the other hand, the availability of alternative methods to chemical weed control, and other unwanted organisms to crops, is still a big challenge. Thus, the aim of this study was to evaluate the effect of solarization on growth and early development of weed plants from seedlings in the soil. The experiment was conducted at University of Cuiabá, between 01/18/2018 and 02/22/2018. A completely randomized design was adopted with five treatments and five replications. The treatments correspond to five times of soil solarization, namely : control (no solarization), solarization for 7 days, 14 days, 21 days and 28 days. The results showed that the solarisation can be applied to the weeds removal. The effects are varied and depend on the solarization time and plant species. Soil Solarization for 14 days showed over 90% reduction of mass production Cyperus rotundus dry matter and solarization for 28 days showed a reduction of approximately 70% by weight of dry matter production of Chamaesyce hirta. The effects are varied and depend on the solarization time and plant species. Soil Solarization for 14 days showed over 90% reduction of mass production Cyperus rotundus dry matter and solarization for 28 days showed a reduction of approximately 70% by weight of dry matter production of Chamaesyce hirta. The effects are varied and depend on the solarization time and plant species. Soil Solarization for 14 days showed over 90% reduction of mass production Cyperus rotundus dry matter and solarization for 28 days showed a reduction of approximately 70% by weight of dry matter production of Chamaesyce hirta.

Native Pastures

ABSTRACT The Maranhão floodplain is dominated by native grasses like capim-açú (Paspalum plicatulum, Mich.). Due to scarce information on nutrient demands of native species, farmers are replacing native pastures by exotic and potentially invasive species such as antelope grass (Echinochloa pyramidalis, Lam). The aim of this study was to compare the growth of capim-açú and antelope grass, under varying N and K doses, to better understand the potential of capim-açú to be used as forage. The experiment was carried out in pots, consisting of a 2 × 5 × 2 factorial scheme (2 species × 5 N doses × 2 K doses) with four repetitions, in a completely randomized design. The N doses of 0, 50, 100, 150 and 200 mg dm-3 were combined with 10 and 30 mg dm-3 K2O. The capim-açú produces higher leaf to stem ratio aboveground by using lower nitrogen and potassium doses than antelope grass. Leaf, stalk, and total dry matter production of both studied species do not respond to potassium doses.

A pot experiment was conducted to evaluate the growth and yield performance of four strawberry germplasms at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during October 2010 to April 2011. The experimental materials were four strawberry germplasms: V1 (SAU Line-01), V2 (SAU Line-02), V3 (SAU Line-03) and V4 (SAU Line-04). The experiment was laid out in a Completely Randomized Design (CRD) with five replications. Among the germplasms the maximum number of flowers (32.5/plant), the maximum number of fruits (28.8/plant), the highest average fruit weight (12.3 g) and the highest total fruit yield (361 g/plant) were found in V1. Considering the overall results of the study, it may be concluded that V1 (SAU Line-01) is a promising strawberry germplasm for cultivation in Bangladesh.
