Bradyrhizobium Inoculation

A field experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University (BAU), Mymensingh during January to May 2015 to study the response of soybean to Bradyrhizobium biofertilizer under different levels of phosphorus on growth, yield, nutrient content and uptake by soybean. The experiment was laid out in a randomize complete block design with three replication of each treatment. The treatments were: To = Control, T1=(100% Nitrogen), T2=(Bradyrhizobium), T3=(Bradyrhizobium inoculation+75% P), T4=(Bradyrhizobium inoculation+10 P), T5=Bradyrhizobium+125% P), T6=(100% RFD+Bradyrhizobium). Potassium and Sulphur at recommended dose were applied as basal to all the treatments. Urea was applied in three spits. Phosphorus in the form of TSP was applied as per treatment during final land preparation. Soybean seeds were inoculated with Bradyrhizobium as per treatments. Intercultural operations were done as and when necessary. Data were collected on pods weight, grain and stover yields. The N and P contents in grain stover and total N and P uptake by soybean were determined. Inoculation of seeds with Bradyrhizobium and application of N and P fertilizer at recommended dose recorded the highest grain and straw yields of soybean. The results suggest that soybean cultivation can effectively be done in the Old Brahmaputra Floodplain soils by Inoculating with Bradyrhizobium biofertilizer in combination with recommended dose of N, P, K and fertilizer.Progressive Agriculture 28 (4): 302-315, 2017

Reduced Rate

Balanced fertilization is a pre-requisite for better rice production and it is necessary to determine optimum combination of nutrient elements for application. An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during Boro season to investigate the effects of reduced rates of phosphorus (P) and sulphur (S) on the growth, yield, nutrient content and uptake by rice. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications and eight treatments viz. T1: Control, T2: Recommended Fertilizer Dose (RFD), T3: RFD -20% P, T4: RFD-40% P, T5: RFD-20% S, T6: RFD-40% S, T7: RFD-20% PS and T8: RFD-40% PS. The recommended fertilizer doses were 125 kg N ha-1, 25 kg P ha-1, 70 kg K ha-1, 15 kg S ha-1 and 3 kg Zn ha-1 supplied from urea, TSP, MoP, gypsum and zinc sulphate, respectively. There was significant effect of reduced rates of P and S fertilizers on rice yield compared to control. The highest grain yield of 5.10 t ha-1 and straw yield of 7.02 t ha-1 were recorded from treatment T2 (RFD) that produced the maximum values of all the yield components and the highest content and uptake of nutrients. The performance of T2 and T3 (RFD - 20% P) was statistically similar in producing yield parameters, yields, nutrient contents and uptake by rice. Again, 20% reduced rate of S (T5) or of P and S (T7) caused significant yield reduction, poor yield parameters and less nutrient uptake compared to T2. Thus, the recommended fertilizer dose and the treatments where 20% P was reduced from the RFD are equally efficient in increasing yield as well as enhancing nutritional quality of rice. This reduction of chemical fertilizer could help lessen the cost of rice production with decreasing environmental risk. Asian J. Med. Biol. Res. March 2021, 7(1): 40-47

Organic Manures

Cotton seed oilcake and mustard oilcake are excellent and high quality organic manures enriched with essential nutrient elements. A field experiment was carried out at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during boro season of 2019 to investigate the influence of cotton seed oilcake and mustard oilcake on yield attributes, yield, nutrient content and uptake by rice cv. BRRI dhan29. The experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications and seven treatments viz. T1: control, T2: 100% Recommended Fertilizer Dose (RFD), T3: 50% RFD, T4: 50% nitrogen (N) from RFD + 50% N from cotton seed oilcake, T5: 50% N from RFD + 50% N from mustard oilcake, T6: 50% N from RFD + 25% N from cotton seed oilcake + 25% N from mustard oilcake, T7: 50% N from cotton seed oilcake + 50% N from mustard oilcake. The maximum values of all the yield components viz. plant height, panicle length, number of effective tillers hill-1 and filled grains panicle-1 and yields (grain and straw) were found in treatment T2. The highest content and uptake of nutrients – N, P, K and S were also recorded in T2. The performance of T4 and T2 was statistically similar in producing yield parameters, grain and straw yields, nutrient contents and uptake by rice. Among the integrated approaches, the performance of T4 was the best as it produced the second highest grain yield of 6.24 t ha-1 and straw yield of 8.17 t ha-1 with higher nutritional improvement of rice. Application of cotton seed oilcake compensated up to 50% of chemical fertilizer. Therefore, considering the significance of organic manures and soil health, cotton seed oilcake should be considered for application in association with chemical fertilizers for yield enhancement and nutritional improvement of rice.

A field experiment was conducted at Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, during the period from February to April, 2008 to evaluate the effect of N and S fertilizers with or without bio-fertilizer (Bradyrhizobium) on yield contributing characters of Binamoog-6. The experiment was laid out in Randomized Complete Block Design (RCBD) with nine treatments and three replications. The treatments were T1-N0S0, T2-N0S5 T3-N0S10, T4-N15S0, T5-N15S5, T6-N15S10, T7-N30S0, T8- N30S5 and T9-N30S10 with or without bio-fertilizer (Bradyrhizobium). Data were recorded at 35 days after sowing (DAS), 49 DAS and at harvest. There were significant variations among the different treatments combination in terms of nodulation, growth, yield and quality. Result showed that Bradyrhizobium inoculation significantly increased the number of pod plant-1, number of seed pod-1, 1000-seed weight, stover yield, grain yield. The highest number of pod plant-1 (18.78), number of seed pod-1 (11.89), 1000- seed weight (43.40gm), stover yield (3.80 t ha-1) and grain yield (1.92 t ha-1) were recorded in IIN0S10 treatment. The result revealed that the inoculation of bio-fertilizer (Bradyrhizobium) significantly increased the yield by positively influencing the yield contributing characters of Binamoog-6.DOI: http://dx.doi.org/10.3329/jesnr.v4i2.10166J.

Moringa Leaf Extract

Moringa is a valuable plant whose leaves are enriched with antioxidants, amino acids, vitamins and mineral nutrients and can be used as a bio-stimulant. A field work was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University (BAU), Mymensingh, during rabi season from November 2017 to February 2018 in order to investigate the effect of moringa leaf extract (MLE) on growth, yield and nutrient status of cabbage. The experiment was laid out in a randomized complete block design with four treatments and three replications. The treatments were T1 (control), T2 (MLE) sprayed at 2 weeks after transplanting only], T3 (MLE sprayed at 2 weeks and 4 weeks after transplanting), T4(MLE sprayed at 2 weeks after transplanting and after every two weeks thereafter). The rate of MLE application was 25 mL plant-1. All the treatments received recommended dose of N, P, K, S, Zn and B fertilizers. The application of MLE significantly improved the growth parameters, yield and yield contributing characters as well as nutrient content and uptake of cabbage. Among the parameters plant height (33.40 cm), leaf number (19.33 cm), length of the largest leaf (29.00 cm), head thickness (9.67 cm), head diameter (20.33 cm), gross yield (72.83 t ha-1) and marketable yield (48.87 t ha-1), were maximum in T4 where MLE was sprayed at 2 weeks after transplanting and after every two weeks thereafter. The lowest values of all these parameters were found in T1 where no MLE was sprayed. Foliar application of MLE also improved the concentration and uptake of macronutrients (N, P, K and S) in head of cabbage. Thus, application of MLE as a bio-stimulant has the potentiality to enhance growth, yield and nutritional quality of cabbage. Asian J. Med. Biol. Res. June 2020, 6(2): 196-203

A field experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University; Mymensingh during December 2012 to May 2013 to investigate the growth, yield and nutrient content of fifteen widely used boro rice cultivars of Bangladesh. The experiment was laid out in a Randomized Complete Block Design (RCBD) with 15 cultivars having each cultivar replicated three times. The cultivars tested in this experiment were BRRI dhan28, BRRI dhan29, BRRI dhan45, BRRI dhan47, BRRI dhan50, BR 3, BR 6, BR 14, BR 15, BR 16, BINA dhan5, IRATOM 24, Bachi boro, Chola boro and Sada boro. BR 15, BRRI dhan29 and BRRI dhan28 were the three rice cultivars having high potentials for grain and straw production during boro season. The highest yield was recorded 5.26 t/ha which is still very low compared to other rice growing countries of the world. So there is plenty of scope to increase the yield. Chola boro and Sada bore are two local land races having potentials for producing higher number of effective tillers and higher 1000 grain weight. Sada boro and Chola boro, two local cultivars were found very high in grain nitrogen content compared to other test cultivars. These two cultivars could be a nice tool for rice breeder to develop high nitrogen content rice. Chola boro, IRATOM 24 and BR 14 are three high straw-K containing varieties having breeding potentials to make our future rice plant strong. Before using these cultivars for breeding, fine tuning of the research findings is required DOI: http://dx.doi.org/10.3329/ralf.v1i1.22352 Res. Agric., Livest. Fish.1(1): 19-25, Dec 2014

Keterbatasan lahan potensial menyebabkan perluasan areal pertanian mengarah pada lahan gambut. Kendala pengembangan lahan gambut adalah rendahnya kandungan hara tersedia bagi tanaman. Fosfat (P) merupakan salah satu unsur hara makro yang penting untuk pertumbuhan dan produksi tanaman, disisi lain ketersediaan hara ini pada lahan gambut terbatas karena ikatan asam organik dan sifat yang mudah tercuci. Penelitian untuk menguji pengaruh ameliorasi dan inokulasi mikroba pelarut fosfat terhadap ketersediaan hara P di lahan gambut dilakukan di kebun pembibitan kelapa sawit petani di Riau dari Oktober 2013 - Maret 2014, menggunakan Rancangan Acak Kelompok pola Faktorial dengan 30 kombinasi perlakuan dan 3 kali ulangan. Variabel yang diamati meliputi : tinggi tanaman, lingkar batang, jumlah daun, lebar daun, panjang daun, kandungan hara tanaman, dan bobot biomasa bibit setelah 5 bulan di pembibitan. Hasil penelitian menunjukkan bahwa ameliorasi menggunakan kompos tandan kosong kelapa sawit mampu meningkatkan P tersedia, serapan P oleh batang dan akar, berat brangkasan dan berat kering batang. Sedangkan mikroba pelarut fosfat berpengaruh secara tidak nyata.The limitation of potential land leads agricultural development expansion to the peat soil area. Constrain of the peatland development is the low nutrient content that is required by plant. Phosphate is one of major growth and production limiting nutrient because of the solublelize of the organic acids and immobility The research was conducted from October 2013 – March 2014 at the farmer main nursery in Riau province to test the effect of amelioration and phosphate solubilizing microbe inoculation on P availability on palm oil seedling growth and production at peatland, used Randomized Block Design with 30 treatments and 3 replications. The parameters observed were plant height, leaf number, leaf width, leaf length, stem diameters, nutrient contents, also fresh and dry weight after 5 months at the main nursery. The result showed that palm oil empty fruit bunch compost as ameliorant increased P nutrient avaibility, P uptake, fresh and dry weight, whereas phosphate solubilizing microbe was unsignificant.

A field experiment was conducted to examine the effects of different nitrogen fertilizers in combination with bacterial fertilizer onnutrient uptake of horseradish and plant available nutrients of the soil. Three different N fertilizers, ammonium-nitrate, urea and calciumnitrate(116 kg ha-1 N) in combination with Microbion UNC bacterial fertilizer (2 kg ha-1) were applied as treatments in a randomizedcomplete block design in three replications. In this paper we presented the results of soil measurements. The soil of the experimental areawas chernozem with medium sufficiency level of N and P and poor level of K.Our main results:The amount of 0.01M CaCl2 soluble inorganic nitrogen fractions, NO3--N and NH4+-N and also the quantity of soluble organic-N werealmost the same in the soil. N fertilizers significantly increased all the soluble N fractions. The amount of NO3--N increased to the greatestextent and the increase of organic N was the slightest. We measured the largest CaCl2 soluble NO3- -N and total-N contents in the plotstreated with ammonium-nitrate, the largest NH4+-N in the plots treated with calcium-nitrate and the largest organic-N fraction in plotstreated with urea.Bacterial inoculation also increased both soluble inorganic nitrogen forms and also total-N content of soil compared to the control. Inthe case of combined (artificial and bacterial fertilizer) treatments we measured lower NO3--N, organic-N and total-N compared to thevalues of plots having only nitrogen fertilizer treatments. On the contrary in the plots with combined treatments the CaCl2 soluble NH4+-Ncontent of soil in more cases were higher than that of values with artificial fertilizer treatment.As a function of calcium-nitrate application increased AL-P2O5 and AL-K2O values were measured compared to control. MicrobionUNC supplement of calcium nitrate yielded also increase in AL-P2O5 and AL-K2O values, till then supplement of ammonium-nitrate fertilizeryielded a decrease in these values compared to the control.All nitrogen fertilizers resulted in a significant decrease in AL-Mg content of soil compared to the control. Nevertheless bacterialfertilizer increased AL-Mg values in any cases.
