A pot experiment was carried out in 2019 in the net house of the Department of Soil, Water and Environment, University of Dhaka, to evaluate the growth and yield of Jute plants (Corchorus capsularies L.) by applying different types of organic manures. Eight different types of organic manures viz. ACI, BGF-1, Mazim, Vermicompost, Shufola, GTS, Green and Poultry manures were collected from the local market. The experiment was set up following a completely randomized design (CRD) with nine treatments and three replications consisting of twenty-seven pots. Significant variation was observed in different growth and yield contributing characters. The highest plant height (19.83cm) in poultry manure, leaf number (8.33/plant) was observed in Green manure, leaf area (21.93 cm2 / plant) in Poultry manure, fresh weight (3.18g) and dry weight (2.25 g) were found in Poultry manure, stem girth (1.67 cm/plant) in Vermicompost, branch number (8.6/plant) in Green manure. The highest nutrient uptake by plants (kg/ha) occurred in Poultry manure. The overall best growth was observed in Poultry manure. J. Biodivers. Conserv. Bioresour. Manag. 2020, 6(1): 17-24

An experiment was set up in the Research Farm of Patuakhali Science and Technology University, during the rabi season of 2015 to evaluate the effect of fertilizers and manures on the growth and yield of Potato. The experiment was laid out in a Randomized Complete Block Design (RCBD) with two potato varieties namely Diamant (V1) and Cardinal (V2) and five different types and rates of organic manures and inorganic fertilizers viz. T0: Control , T1: NPK, T2: NPK + CW(Cowdung), T3: NPK+ PM(Poultry Mannure) and T4: CW(Cowdung), + PM(Poultry Mannure)  were used for the present study. The two–factor experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Result showed that almost all the characters were affected significantly due to the effect of varieties, organic–inorganic fertilizer and their combinations .In case of treatments, NPK with PM also showed the tallest plant (39.76 cm), highest fresh and dry weight (95.97 and 6.05 g plant–1, respectively), CGR and RGR (0.086 and 0.218 g m–2 day–1, respectively), gross (24.36 t ha–1) and marketable (23.39 t ha–1) compared other treatments. In case of interaction, the highest plant height (41.00 cm), highst fresh and dry weight (96.87 and 3.62 g plant–1, respectively), highest CGR and RGR (0.089 and 0.228 g m–2 day–1, respectively) as well as the highest gross (24.45 t ha–1) and marketable (23.67 t ha–1) yield were recorded in Diamant at NPK with PM. From the above observation it may be concluded that the variety Diamant at NPK + PM was more effective under Patuakhali region.Progressive Agriculture 27 (4): 435-443, 2016

A field study was conducted at experimental farm of the Regional Research Station, Punjab Agricultural University, Gurdaspur during rabi season of 2014-15 to find out the effect of different sources of organic manures and their combinations on weed growth and wheat grain yield. The experiment was laid out in randomized block design with eight treatments namely, control (T1), recommended dose of NPK+ weedicide (T2), farmyard manure + poultry manure (T3), farmyard manure + bagasse ash (T4), farmyard manure + rice husk ash (T5), poultry manure + bagasse ash (T6), poultry manure + rice husk ash (T7), and bagasse ash + rice husk ash (T8). The results indicated that maximum dry weight of grassy weeds (2.65 g/m2) and broad leaf weeds (2.10 g/m2) was recorded in treatment where poultry manure was used in combination with farmyard manure whereas minimum dry weight of grassy (1.15 g/m2) and broad leaf weeds (1.00 g/m2) was obtained in treatment where these were controlled chemically. The minimum grain yield was obtained in control treatment where neither organic manure was added nor weeds were controlled by using herbicide. Among different combinations of organic manures, it was found that wherever poultry manure was used in combinations, higher yields were obtained due to higher plant height, maximum number of effective tillers/m2, maximum spike length in comparison to other manure combinations. Within the treatment combinations, rice husk ash combinations resulted in higher yield and also effectively controlled the weeds as compared to bagasse ash combinations.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya.

Abstract This study aimed to identify the optimum rice stem cutting size combined with the application of Seprint liquid organic fertilizer (SLOF) to promote the growth and yield of ratoon rice. This research was conducted in a greenhouse at the Faculty of Agriculture, University of Muhammadiyah Sumatera Utara, North Sumatra Province, Indonesia, from January to August 2018. The experiment was set up as a completely randomized design factorial with four replications. The first factor consisted of the cutting sizes of the rice stem (R1 = 5 cm, R2 = 10 cm, and R3 = 15 cm) and the second factor involved the SLOF dosage (S1 = 5 mL L −1 , S2 = 10 mL L −1 , and S3 = 15 mL L −1 ). The parameters were analyzed using analysis of variance (ANOVA), and the means were determined by Duncan’s multiple range test (DMRT). The results showed that the R2 treatment significantly increased the ratoon rice height at 10 to 30 days after cutting (DAC), the number of tillers at 40 to 60 DAC, the number of productive tillers, and the yield per hectare. The S2 and S3 applications at significantly increased the yield per hill and ratoon rice height at 20 DAC. The R2S1 and R2S2 combination treatments significantly increased the number of filled grains per panicle and the ratoon rice height at 10 DAC. Cutting the stems at 10 cm combined with various dosages of SLOF resulted in greater growth and yield of ratoon rice for achieving an adequate food supply.

Turmeric is an important spice crop of Bangladesh. A field experiment was conducted at farmer’s field of North Jhatibunia, Mirzagonj, Patuakhali during April, 2015 to February, 2016. The study was performed to find out the effect of green manure and nitrogenous fertilizer on the growth and yield of turmeric (BARI Halud-2), in coastal region of Bangladesh. In this study different combinations of green manure along with nitrogenous fertilizer were used. There was eight treatment combinations (viz. 7 ton biomass/ha + 100 kg N/ha, 7 ton biomass/ha + 80 kg N/ha, 7 ton biomass/ha + 60 kg N/ha, 7 ton biomass/ha + 40 kg N/ha, 7 ton biomass/ha + 20 kg N/ha, 7 ton biomass/ha, 100 kg N/ha and control). The highest number of leaves per plant (11.67) were recorded by the combined application of 7 ton biomass/ha along with 100 kg N/ha. The highest plant height (80.70 cm) and the longest leaf length (47.33 cm) were recorded by the application of 100 kg N/ha. The highest number of tillers per plant (7.67), maximum number of primary rhizomes per plant (9.00), maximum fresh weight of clump (189.67 g), highest fresh weight of roots (48.01 g), maximum fresh weight of rhizomes (277.70 g), maximum dry weight of clump (20.01 g), highest dry weight of roots (9.25 g), maximum dry weight of rhizomes (67.50 g) and maximum yield of fresh rhizome per hectare (6.64 tons) were recorded by the combined application of 7 ton /ha biomass+ 40 kg N/ha. Highest number of secondary rhizomes per plant (17.00) and maximum number of tertiary rhizomes per plant (7.00) were recorded by the application of 7 ton biomass/ha + 60 kg N/ha. With a few exception, the best performance in terms of growth and yield of turmeric were found from the combination of 7 ton biomass /ha + 40 kg N/ha.

Bambara groundnut (Bogor groundnut) was an alternative food crops having high nourishing, better taste and bigger size nut than the soy beans and peanuts. To meet the need for food and industrial needs, the program to increase production of Bogor groundnut was required, one of which is the use of peat as a growing medium using the technology of mixing peat and mineral soil. The research objective was to obtain a mixture of peat with mineral soil and dolomite lime dose suitable for the highest growth and yield of Bogor groundnut.  This study was conducted in May 2015-September 2015 in the Greenhouses of Faculty of Agriculture, University of Bengkulu. The experiment was arranged in a completely randomized design (CRD) with two treatment factors and three replications. The first factor was soil mix of peat and mineral soil (G0: 100% peat + 0% mineral soil; G1: 75% peat + 25% mineral soil; G2: 50% peat + 50% mineral soil; G3: 25% peat + 75% mineral soil) and the second factor was the dose of dolomite (D0: without lime dolomite; D1: 3 ton ha-1 and D2: 4 ton ha-1). The results showed that the response of biomass dry-weight to a mixture of peat with mineral soil was influenced by the dose of dolomite, but there was no interaction on other variables.  Treatment of a mixture of peat 100% alone was capable of generating the highest number of leaf, biomass fresh- and dry-weight.  Bogor groundnut plants showed the same response to the dose variation of dolomite lime.Keywords: Bogor groundnut, peat, mineral, dolomite

Background and Objective: Unproductive soil has been a major problem to farmers, recent interest in the use of a stable organic manure (biochar) as soil amendment and poultry manure to increase soil fertility is also increasing. Hence, the experiment was conducted to assess the condition of poultry manure and biochar on the growth and yield of tomato. Materials and Methods: A greenhouse experiment was conducted at the Federal College of Forestry Ibadan, using polyethylene bag with 5 kg soil collected at two (2) soils depths, 0-15 cm and 15-30 cm depth at the botanical garden, Federal College of Forestry Ibadan. The experiment was arranged in a completely randomized design (CRD) with four replicates. The treatments used were poultry manure (5t/ha), biochar (10t/ha), mixture of poultry manure and biochar (1:1) and control (no amendment).The tomato seeds (UC82B) were sourced from NIHORT, Ibadan and raised in a germination basket. Data were collected weekly on plant height, collar diameter and number of leaves, 50% days to flowering and yield of tomato plants from two weeks after transplanting (WAT). Data collected were analyzed statistically using ANOVA while means were separated using LSD (p<0.05) where applicable. Results: In 0-15 cm soil, the growth variables (plant height, number of leaves and collar diameter) increased with various treatments used. The highest tomato height was observed with the application of biochar (10t/ha). All the treatments applied affected the number of tomato leaves at all weeks after transplanting (WAT) with poultry manure 5t/ha having the highest number of leaves at 7WAT, while collar diameter was significantly affected by various treatments from 2 to 5 WAT, with the mixture of P.M + BIO (1:1) recording the highest value and the control plot recorded the least values in all weeks. However, in 15-30 cm soil, there was  significant difference in the number of leaves of tomato among all the amended soil from 5 to 7 WAT, the highest tomato leaves were obtained when the soil was amended with poultry manure (5t/ha) and can be compared with other treatments. Interaction of poultry manure and biochar(1:1) and poultry manure 5 t/ha resulted in highest height of tomato plant from 3-7 WAT as compared to the control that had the least value but were not significantly different from the sole application of  biochar 10t/ha. Interaction of poultry manure + biochar (1:1) and poultry manure (5t/ha) gave the highest tomato flowering and fruits. Conclusion: Based on this result, biochar and poultry manure when added to soil, boosted the mineralization of the soil after amendment.

This study was carried out to ascertain the effects of organic manure (farmyard manure, poultry manure, and vermicompost) and chemical fertilizers NPK (nitrogen, phosphorus, and potassium) on the growth and yield of onion. The research was consisting ten treatments with three replications. Different levels of nitrogen (0, 100, and 150 kg ha-1), phosphorus (0, 75, and 100 kg ha-1), potassium (0, 80, and 100 kg ha-1) fertilizers, and various rates of organic manures (20 ton ha-1 of farmyard manure, 20 t ha-1 of poultry manure and 15 t ha-1 of vermicompost) were applied to the soil at different combinations. The results of this study have shown that both inorganic fertilizers and organic manures significantly influenced all growth and yield parameters. Whereas, maximum plant height (50.50 cm) and bulb yield (30.75 t ha-1) were obtained at the combination of 20 t ha-1 farmyard manure + 150 kg ha-1 N + 100 kg ha-1 P2O5 + 100 kg ha-1 K2O. However, the minimum bulb yield (15.80 t ha-1) was observed with control where no fertilizer was applied. Therefore, application of 20 t ha-1 farmyard manure during field preparation followed by application of 150 kg ha-1 N + 100 kg ha-1 P2O5 + 100 kg ha-1 K2O can be recommended for optimal growth and maximum bulb yield of onion.
