Organic Manures

A field experiment was conducted during 2003-2004 at Bangladesh Agricultural University farm, Mymensingh to evaluate the suitability of different sources of organic materials for integrated use with chemical fertilizers for the Boro-Fallow-T. Aman rice cropping pattern. The experiment was set up in a randomized complete block design (RCBD) with three replications. Eight-treatments, formulated from organic manure and chemical fertilizers have been imposed. The treatment combinations are T1: control, T2: 70% NPKS, T3: 100% NPKS, T4: 70% NPKS + rice straw (RS) @ 5 t/ha, T5: 70% NPKS + dhaincha (DH) @ 15 t/ha, Tb: 70% NPKS + mungbean residue (MBR) @ 10 t/ha, T7: 70% NPKS + cowdung (CD) @ 5 t/ha and T8: 70% NPKS + poultry manure (PM) @ 3 t/ha. Organic manure or crop residue was applied to T. Aman rice and their residual effects were observed in the following Boro rice. Application of 70% NPKS + PM produced the highest grain yield of T. Aman rice, which was identical to that obtained with 100% NPKS with no manure. In Boro season. application of 100% NPKS produced the highest grain yield of 6.87 t/ha, which was identical with the application of 70% NPKS + PM (6.57 t/ha). The total grain yield in the cropping pattern ranged from 5.14 t/ha in T1 (control) treatment to 12.29 t/ha in the 100% NPKS. The application of 3 t/ha PM with 70% NPKS (T8) produced the total yield of 12.09 t/ha followed by 11.59 t/ha in the treatment containing 10 t/ha MBR plus 70% NPKS (T6). It appears that the application of 3 t/ha PM once in a year with 70% NPKS can reduce the use of 30% NPKS as fertilizers. There were negative balances for N and K with the highest mining of K, while the balances for P and S were positive. The economic analysis reveals that most of the treatments produced BCR (benefit-cost ratio) of more than 3.0 showing that they all are economically viable. The integrated use of fertilizers and manure resulted in considerable improvement in soil health by increasing organic matter, available P, and S contents of soils. The overall findings of the study indicate that the integrated use of chemical fertilizer and manure is important for sustainable crop yield in a rice-rice cropping pattern.

Different combinations of chemical fertilizers and organic manure were applied for sustainable crop productivity in the cauliflower-stem amaranth -jute cropping pattern. The experiment was conducted at farmer’s field in Multilocation Testing (MLT) site of Pakshi, Pahna over three years. There were five combinations of chemical fertilizers (CF) and poultry manure (PM) along with absolute control arranged in a randomized complete block design. The results revealed that all three crops showed significant yield for fertilizer and poultry manure use. Higher yields were obtained with 50% CF + 50% PM followed by 75% CF + 25% PM treatments where cauliflower equivalent yield was increased by 85% and 78%, respectively, over control. This indicates a positive residual effect of poultry manure on the subsequent crops. From the economic points of view, the highest marginal benefit cost ratio (MBCR) was attained in 100% chemical fertilizer due to its lower variable cost followed by 75% CF + 25% PM treated plots. However, gross margin was higher in 50% CF + 50% PM combination for its higher total yield. Key Words: Chemical fertilizer; poultry manure; productivity. DOI: 10.3329/bjar.v34i1.5761Bangladesh J.

A pot experiment was conducted in the net house of the Agronomy department, Sher-e-Bangla Agricultural University, Dhaka during the period from November, 2018 to March, 2019 to evaluate the suitable organic source to mitigate the drought stress impact on wheat. The experiment comprised two factors viz. factor A: Three levels of organic manures, i)  O0 = Control (Without organic manure),       ii) O1 = Cowdung (10 t/ha), iii) O2 = Poultry litter (5 t/ha), and factor B:  four levels of drought i) D0 =  Control (without drought), ii) D1 =  Crown root initiation stage (at 20-29 DAS), iii) D2 =  Booting stage (at 45-54 DAS), iv) D3 = Anthesis stage (at 55-64 DAS). The experiment was laid out in a completely randomized design (factorial) with three replications. Organic manure showed positive impact on yield and cowdung (O1) gave the highest grain yield (4.06 g plant-1). This may be attributed to the highest number of effective tillers plant-1 (3.21), spike length (9.53 cm), spikelet spike-1 (17.31), grains spikelet-1 (2.31) and 1000-grain weight (44.61 g) of wheat in this treatment. In respect of drought imposition treatments, grain yield was found higher in control treatment (without imposition of drought) which was statistically similar with drought imposition at booting stage treatment (D2). These two treatments also showed highest number of effective tillers plant-1, spikelets spike-1, grains spike-1 and 1000-grain weight. Regarding the interaction of organic manure and drought, cowdung without drought imposition (O1D0) and cowdung with drought imposition at booting stage (O1D2) were highest yielder among the other interactions which was attributed to higher 1000-seed weight, number of effective tillers plant-1, spikelets spike-1 and grains spike-1. Results revealed that application of organic manure could reduce the impact of drought on wheat irrespective of growth stages. However, application of cowdung (10 t ha-1) was found more effective to combat drought impact at booting stage of wheat compared to other growth stages. Bangladesh Agron. J. 2020, 23(2): 81-86

Field experiment on Tomato-Okra-Indian spinach cropping pattern was     conducted at a farmer’s homestead of Tangail (AEZ 8) during 2007-08 and 2008-09 to find out a suitable combination of chemical fertilizers and organic manure for sustainable crop yield. There were 5 treatments comprising different percentages of the recommended chemical fertilizers (RCF) with two levels (0 and 5 t/ha) for tomato and three levels (0, 2.5 and 5 t/ha) for okra each of poultry manure and cowdung. No organic manure was used for the third crop Indian Spinach. The treatments were arranged in Randomized Complete Block Design with four replications. An amount of 75% dose of RCF (N150P40K80S20Zn2B1 kg/ha) along with poultry manure @ 5 t/ha appeared as the best suited combination providing tomato yield 95.3 t/ha and 88.2 t/ha for the first year and  second year, respectively. Again, an amount of 75% dose of RCF(N120P35K70S15Zn2B1 kg/ha) along with poultry manure @ 2.5 t/ha appeared as the best package providing the highest okra yield (15.03 t/ha and 12.98 t/ha). The highest yield (36.3 t/ha and 33.7 t/ha for the first and second year, respectively) of Indian Spinach was recorded from (75% recommended N + PM residue), which was statistically identical with (100 % recommended N), but significantly higher over rest of the treatments. Poultry manure performed better over cow dung. A package of 75% recommended chemical fertilizer along with 5 t PM/ha appeared as the best suited combination providing higher yield and economic return.

The use of natural hormone of sprout extract, coconut water, and banana stem extract and application of cow biourine has been introduced as an innovation to reduce the use of chemical fertilizers to increase the productivity of shallot. This study aims to compare the growth and yield of shallot with chemical fertilizer treatment and that of shallot treated with combination of natural hormone and cow biourine. The study was conducted in Temon Wetan, Temon, Kulon Progo, Special Region of Yogyakarta using a Complete Randomized Block Design, which consists of two factors and one control (chemical fertilizer). The first factor is a natural hormone: sprout extract, banana stem extract and coconut water. The second factor is the concentration of cow biourine: 30%, 40%, and 50%. Data were analyzed using diversity at 5% level, Orthogonal Contras at 5% level and DMRT Test with 5% level. It was revealed that the control group with a combined treatments was not significantly different from the growth and yield of shallot of the group with chemical fertilizers. Types of treatments with natural hormone and cow biourine concentrations provided the same growth and yield as that of chemical fertilizer.
