2.7 billion people worldwide rely on onsite sanitation and it is a big problem in developing countries. Faecal sludge is a good source of micro/macronutrients of plant besides its richness in organic matter. Two consecutive field experiments was conducted in BRAC Agricultural Research and Development Centre, Gazipur during Rabi 2015-16 and rabi 2016-17 aimed to determine the effect of faecal sludge on crop production and how much dosage need for maximum yield. Cabbage was the test crop. It was observed that harvesting time was significantly shortened and 25.51% curd weight and 26.55% yield was increase with addition of faecal and chemical fertilizer. No significant differences were found on the dosage of faecal on head formation and head diameter. In the addition of full dosage of faecal with chemical fertilizer, 41.04% and 8.61% curd weight increase than only faecal and chemical fertilizer. Application of full dosage of faecal with full dosages of chemical increases yield 7.28%, 10.66%, 6.88% and 38.75 % than application of half faecal, three-fourth faecal, only chemical fertilizer and only faecal. So addition of full dosage of faecal with chemical fertilizer gives the highest yield on crop. In Bangladesh, faecal might be recycled into agricultural soils as a supplement to commercial fertilizer and thereby enrich the general fertility of the soils and increase crop production.Int. J.

Currently, a real challenge for the workers in the agricultural research field is to stop or reduce the use of expensive agrochemicals/ chemical fertilizers which are hazardous to the environment as well as human health. Present study was aimed to improve the growth and obtain optimum yield of Vigna crop with eco-friendly, non-toxic way and to reduce the use of agrochemical/chemical fertilizer application in agricultural activities. A pot experiment was conducted to study the effect of chemical fertilizer (DAP) and biofertilizer ( Rhizobium strain) separately and in combination on seed germination and seedling growth (at 30 days) based on morphological parameters such as seedling length (cm), fresh weight (g), dry weight (g) and leaf area (cm)2 of Vigna radiata (L.) Wilczek. After one month (30 Days) observations, it was found that seedling length, fresh and dry weights and leaf area were maximum in T4 and minimum in T15, T7 and T8 favored improved seedling length and leaf area whereas T7, T8, and T9 favored improved fresh and dry weights as compared to control.

Digestate and biogas slurry (BS) are the byproduct of biogas engineering that could be used for elevating plant growth. However, the consequent emissions of ammonia from BS are considered a severe threat to the atmosphere. Herein, we conducted two consecutive field experiments with wheat–maize rotations to find out the optimum ratio of BS to combine with chemical fertilizer (CF) to reduce ammonia volatilization (AV) while keeping the stable crop yield. In maize season, 226.5 kg N/ha of CF was applied. In wheat season, 226.5 kg N/ha was applied at different ratios (100%, 80%, and 50%) between BS and CF. Our results found that the maximum yield of 6250 kg/ha was produced by CF, and this yield could be obtained through a combined application of 38% BS mixed with CF. Highest AV produced of 16.08 kg/ha by CF. BS treatments significantly reduced the emission from 18% to 32% in comparison to CF. The combined application of BS-CF produced the highest yield due to essential nutrients coming from both BS-CF. Subsequently, it reduced the AV depending on fertilizer type and fertilizer rate. An optimal ratio of 38% BS was recommended to produce the highest yield and lowest ammonia emissions. The application of BS together with different ratios of CF could be an alternative agricultural strategy to obtain desired crop yield and reduce AV in North China Plain (NCP).

The effect of lime and fertilizer application, as the management of soil acidity, on the growth and yield of rice cv. BRRI dhan50 was investigated during Aman rice season at the Agronomy Field Laboratory of Sylhet Agricultural University, Bangladesh. The experiment was consisted of two factors namely lime and fertilizer. There were four levels of lime (0, 0.50, 1.00, and 1.50 t ha–1 of CaCO3.MgCO3) and three levels of fertilizers (control, FYM @ 10 t ha–1, and chemical fertilizer @ 100-30-42-4-3-0.4 kg ha–1 of N-P-K-Ca-S-Zn). The experiment was laid out in a randomized complete block design with three replications where the unit plot size was 4.0 m x 2.5 m. Growth parameters, yield components and yield of BRRIdhan 50 rice increased with increasing lime rate in association of fertilizer in acidic soil. The highest grain yield (2.90 t ha–1) was recorded from the application of 1.50 t ha–1 lime and the lowest (2.06 t ha–1) was from control (0t ha–1), irrespective of fertilizer. On the other hand, the best effect of fertilizers on grain yield (3.08 t ha–1) was found with the application of FYM @ 10 t ha–1 and the lowest yield (1.59 t ha–1) was in control. The treatment combination of lime 1.50 t ha–1 and FYM (@ 10 t ha–1 produced the highest grain yield (3.60 t ha–1), which was followed by treatment combination of lime 1.50 t ha–1 and chemical fertilizer @ 100-30-42-4-3-0.4 kg ha–1 of N-P-K-Ca-S-Zn (3.28 t ha–1). Additionally, application of lime and FYM improved the soil fertility and properties of acidic soil for crop production by increasing the pH, organic matter and availability of some essential nutrients. From the study, it was indicated that both FYM and lime could affect to enhance the grain yield of rice in acidic soil. J. Bangladesh Agril. Univ. 16(3): 357–365, December 2018

Sulfur (S) efficiency parameters were evaluated in soybean-wheat cropping systems in relation to rates of applied S in field experiments on Typic Haplusterts. The parameters evaluated were grain yield per kg fertiliser S applied, S harvest index (SHI), S utilisation from soil (SUS), and fertiliser (SUF) and S efficiency ratios measured as grain yield per kg S uptake by the shoot or grain yield per kg S uptake by the grain. In addition, grain and straw yields, S uptake by both crops, and fertiliser S requirements for optimum production of the 2 crops were also studied. Both soybean and wheat crops responded significantly to S when applied at 0-40 kg/ha on S-deficient soils. The calculated optimum rates of application of fertiliser S to achieve 90% of the maximum yield were 19-38 kg S/ha for soybean and 28-33 kg S/ha for wheat over the 2-year period. The efficiency of crop production as measured by grain or seed yield per kg S applied was greater at lower rates of S application; however, when fertiliser S was applied at a higher rate than 40 kg S/ha, the efficiency declined. Wheat produced more grain yield per kg S applied than soybean. The SHI indicated more efficient translocation of S to soybean seeds than wheat grain. The SUF was greater in wheat, whereas SUS was similar in both soybean and wheat.

Climate change has an impact on Indian agriculture in various direct and indirect ways besides affecting the lives and livelihood of millions of Indians. Efficient management of natural resources is key for enhancing the adaptive capacity of the system and contributes towards the resilience of communities. Successful crop production in frequent drought and flood-affected regions depends on how effectively we conserve the deficit rainfall and manage the excess rainfall and soils to retain the moisture for longer periods for successful arable crop production. The present study was conducted with the objective of evaluation of the performance of different in situ Water conservation measures with respect to the climatic variability prevailed in the village. Demonstrations of appropriate practices and technologies recommended by the National Agricultural Research System (NARS) are being taken up in a farmer participatory mode so that the communities become familiar with these technologies and help in their adoption resulting in enhancing their adaptive capacity and coping ability against climatic change and variability. It was observed that the use of forest leaves and paddy straw was found very profitable to conserve soil moisture in situ with BCR Rs. 7.16 followed by the use of naturally occurred leaves in fruit plants with BCR Rs. 6.22 and use of plastics in vegetables with BCR 4.41. Respondents opined that the use of natural mulch was very cost-effective as well as it is compatible with the existing farming system and very simple in its application. Wheat with cultivation through ZTD showed a maximum yield of 46q/ha. Zero tillage technology showed very promising results in pulse and oilseed cultivation.

Cash Crop

Living mulch systems allow cover crops to be grown during periods of cash crop production, thereby extending the duration of cover crop growth and associated beneficial agroecosystem services. However, living mulches may also result in agroecosystem disservices such as reduced cash crop yields if the living mulch competes with the crop for limiting resources. We examined whether the effects of an Italian ryegrass [Lolium multiflorum (Lam.) Husnot]–white clover (Trifolium repens L., cv. New Zealand) living mulch on broccoli (Brassica oleracea L. var. italica) yield and yield components were dependent on fertilizer rate in field experiments conducted in Durham, NH, in 2011 (Expt. 1) and 2012 (Expt. 2). Drip-irrigated broccoli was grown under a range of organic fertilizer application rates in beds covered with plastic, with and without a living mulch growing in the uncovered, interbed space. Broccoli yields were similar in the living mulch and bare soil controls under the highest rates of fertilizer application in Expt. 1. In Expt. 2, living mulch reduced broccoli yields from 28% to 63%, depending on fertilizer rate. Differences in leaf SPAD values suggest that yield reductions were attributable, in part, to competition for nitrogen; however, other factors likely played a role in determining living mulch effects. Despite yield reductions, the living mulch reduced the prevalence of hollow stem in broccoli in Expt. 1. Organic fertilizer may have inconsistent effects on broccoli yields in living mulch systems.

A field trial was conducted to validate some fertilizer application approaches for Boro-Green manure (GM) -T. Aman cropping system at the Bangladesh Rice Research Institute (BRRI) Farm, Gazipur (AEZ-28: high land) during the period from Boro 1999-2000 to T. Arnan 2000. Five different application approaches of inorganic and organic fertilizers along with their residual values were evaluated. A positive effect of GM on the yield of T. Aman rice was observed. Application of cowdung (CD) @ 6 t/ha (at 15 % moisture) along with integrated plant nutrient system (IPNS) based chemical fertilizer in Boro season followed by green manuring with dhaincha (in Kharif-l season) and then growing T. Aman rice (in Kharif-ll season) with reduced doses of chemical fertilizer (60% N, 50% P, 50% K, and 50% S) substantially increased grain yield and narrowed down the N, P, and K balance in soil. This fertilizer application approach may be practiced for sustainable crop production. No appreciable yield loss in T. Arnan rice (2nd crop) occurred due to the application of reduced doses of P, K, S, and Zn indicating the beneficial residual effect of fertilizer applied to the first crop (Boro rice) of the cropping pattern. The N uptake was in excess of the N added as fertilizer. An improved balance of P, S, and Zn was observed. But the K balance was negative. However, application of cowdung and incorporation of dhaincha slightly improved the K balance of the soil. The highest gross return of Tk. 86,270 was obtained with the above practice (treatment T4)Key Words: Chemical fertilizer; application; wet land rice.DOI: 10.3329/bjar.v34i1.5747Bangladesh J. Agril.

Field experiments were conducted at the Ohio Agricultural Research and Development Center in Wooster, OH in 2002 and 2004 to evaluate the tolerance of tomato varieties to halosulfuron-methyl, a selective herbicide used for POST control of broadleaf weeds and nutsedge (Cyperus). POST herbicide treatments included halosulfuron-methyl at 0, 34.7 and 70 gaiha−1. Plots were evaluated at 1, 3, and 6 wk after treatment (WAT), and yield was recorded at the end of the season. Minimal crop injury was observed 1 and 3 WAT in plots treated with both halosulfuron-methyl rates only in 2002. Although the crop recovered from herbicide injury when treated with the lower rate at 6 WAT, ‘Ohio 8245’, ‘M82’, and ‘E6203’ showed injury at this interval when treated with halosulfuron-methyl at 70 g ha−1. No injury was observed with either rates in 2004. No significant yield reduction was observed in any of the varieties in the test plots. These results indicate that differential tolerance to halosulfuron-methyl does not exists among these tomato varieties with the exception of E6203 and M82.
