A field experiment was carried out at the research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, during rabi (winter) season of 2016-17 to evaluate the effects of fertilizer treatments on black cumin (BARI Kalozira-1). The field belongs to Shallow red-brown terrace soil of Salna series under AEZ-28 (Madhupur Tract). The experiment was laid out in randomized complete block design (RCBD) with three replications. Results showed that the application of nutrient elements had positive effect on plant height, branches per plant, capsule setting, umbels per plant, capsules per plant, capsule size, seeds per capsule, 1000-seed weight and seed yield of black cumin. The highest seed yield (1277 kg ha-1) was obtained from 75% RDCF + 25% cowdung-N treatment followed by 100% RDCF (N80P45K50S20Zn5B2 kg ha-1) and the lowest seed yield (420 kg ha-1) was recorded with 50% RDCF. Thus, the IPNS treatment 75% RDCF + 25% cowdung-N appeared to be the best suitable package for black cumin cultivation in this location.Bangladesh J. Agril. Res. 43(2): 205-210, June 2018

A field experiment was conducted at Char Jangalia under MLT site, Laxmipur, a coastal district of southern Bangladesh, during Rabi season of 2015-16 to evaluate the effect of integrated nutrient management on growth and yield performance of soybean (var. Glycine max L.). Six treatment combinations, viz. T1= Control, T2= Farmers practice (25-15 Kg NP ha-1, T3= 100% recommended dose (30-25-55 Kg NP ha-1, K), T4= 50 % recommended dose + 1.5 t ha-1 vermi compost, T5= 50 % recommended dose + 5 t ha-1compost and T6=50 % recommended dose + 1.2 kg ha-1 bio fertilizer were tested. The experiment was laid out in randomized complete block design with 3 replications. There were significant differences among the different treatment combinations in terms of yield and yield contributing characters. Integrated nutrient management with application of 50% of the recommended doses of urea, TSP, MoP, and biofertilizer (Bradyrhizobium) at the rate of 1.2 kg ha-1 significantly increased most of the parameters, such as the plant height, number of nodule per plant, pods per plant, seeds per pod and seed yield. The highest seed yield (2.93 t ha-1) was recorded from T6 while the lowest seed yield (1.83 t ha-1) was obtained from T1. The highest gross return (Tk.117200 ha-1) and gross margin (Tk. 71840 ha-1) was obtained from T6, whereas the lowest gross return (Tk. 70400 ha-1) and gross margin (Tk.27880 ha-1) was obtained from T1. The overall results indicated that the application of integrated nutrient management of a combination of bio fertilizer with 50% N-P-K (15- 12.5-27.5 Kg ha-1) of the recommended dose produced the maximum nodulation and seed yield of soybean in the southern coastal char land.Bangladesh Agron.

An experiment was conducted at the Sher-e-Bangla Agricultural University farm from April to June 2017 in Kharif season to evaluate the performance of two mungbean varieties under different NPK fertilizers doses in field conditions. The experiment was laid out in Randomized Complete Block Design (RCBD), comprising six treatments with three replications. In the experiment, varieties used were BARI mung-6 and BARI mung-5 and the combination of the treatment were T0 = (control), T1 (10-40-25 NPK kg ha-1), T2 (10-60-45 NPK kg ha-1), T3 (20-50-35 NPK kg ha-1), T4 (30-40-25 NPK kg ha-1) and T5 (30-40-45 NPK kg ha-1), respectively. Mungbean cultivars responded noticeably to the supplementary NPK fertilizers as the crop characters were significantly influenced by different levels of NPK fertilizers. Data were recorded on plant height, leaves plant-1, branches plant-1, pods plant-1, seeds pod-1, 1000-seed weight, seed, and straw yield at different days after sowing. Of the two varieties, BARI mung-6 gave the highest seed yield (1.72 t ha-1) next to the higher plant growth and straw yield On the contrary, BARI mung-5 cultivar produced the lowest seed yield (1.57t ha-1), plant growth, and straw yield. The results showed that T3 (20-50-35 NPK kg ha-1) treatment was the best treatment as regards plant growth and yield parameters. The highest seed yield was produced by treated plot T3 (20-50-35 NPK kg ha-1) over the untreated control plot, T1, T2, T4, and T5, respectively. As for the combined effect, V1T3 (BARI mung-6 and T3 = 20kg N + 50kg P + 35kg K ha-1) performed the best results in all growth and development characters. Therefore, the combined application of 20-50-35 kg NPK ha-1 might be considered to be found optimal to get a considerable seed yield of mungbean variety BARI mung-6.

Tuberose (Polianthes tuberosa L.) is a perennial summer flower grown by smallholders in Kenya for export. However, its production and export volumes have declined drastically due to nematodes infestation. This study evaluated the effect of Cleome gynandra accessions on nematode management on tuberose. Experiment was conducted at the Horticulture Research Field, Egerton University, Kenya using a randomized complete block design with four replications. The treatments were: five accessions of C. gynandra namely ‘Simlaw’, ‘Egerton’, ‘Taastrup’, ‘PS’ and ‘IP8’, applied at 6 kg/m2 and compared with Brassica napus, solarization and untreated control. Data was collected on growth and yield parameters, nematode infestation and quality of tuberose. Data collected was subjected to analysis of variance at p≤0.05 and means separated using Tukey’s test. Biofumigation with Cleome gynandra accessions helped to reduce nematode population by 34%, gall numbers by 83% and galling index by be 96% when compared with the control. Use of biofumigation helped to improve plant height and leaf number of tuberose by 16% and 87%, respectively, when compared with the control. Use of biofumigation helped to improve spike length by 32%, marketable spikes by 80%, and flower yield by 90% and reduced nonmarketable spikes by 95% when compared with the control. Based on the above results, use of Cleome gynandra accessions and other biofumigants such as rape seed can be used to manage nematodes and improve growth, yield and quality of tuberose.

The experiment was conducted in the Dekarhaor of Noagaon village under South Sunamganj Upazila of Sunamganj district during November 2017 to February 2018 to observe the effect of nutrients management on growth and yield of cauliflower hybrids. Two Hybrids namely ShiraGiku (V1) and Rupali (V2), and four combinations of nutrients, viz. (i) recommended rate of N-P-K-S-Zn-B @ 180-80-180-28-4.5-2.1 kg ha-1(F1), (ii) F1 + 25% N-P-K- S-Zn-B of F1 (F2), (iii) F1 – 25% N-P-K-S-Zn-B of F1 (F3), and (iv)  cow dung @ 10 t ha-1 (F4)  was conducted in a factorial randomized complete block design (RCBD) and replicated thrice. Plant height (cm), numbers of leaves plant-1, leaf length (cm) and leaf breadth (cm), and spreading diameter (cm) were collected at 15 days intervals, while the yield data were recorded at harvest. The parameters were significantly varied due to hybrids and fertilizers packages. Higher gross yield (42.52tha-1) was found in Shira Giku and lower (42.12 t ha-1) from Rupali. Higher curd yield of 25.17 t ha-1 was obtained in Shira Giku than Rupali (9.61 t ha-1). The highest gross yield of 44.45 t ha-1 was obtained when the crop was treated with cowdung @ 10 t ha-1 followed by recommended fertilizer rate (F1). The curd yield of 18.19 t ha-1 was obtained with 25% less than recommended fertilizer rate of application (F3). The highest gross yield of 52.93 t ha-1 was obtained in V1F1 combination and the lowest of 30.10t ha-1in V2 F1. Results revealed that the Hybrid ShiraGiku with recommended dose of fertilizer (180-80-180-28-4.5-2.1 kg ha-1N-P-K-S-Zn-B) performed the best in comparison to other treatment combinations.

During integrated nutrient management involving poultry manure (PM) and urea fertilizer (UF) for maize (Zea mays L.), it is necessary to investigate the best time to apply UF that will optimize soil chemical properties, growth, and yield of maize. Hence, studies were carried out to investigate the effect of different rates of PM and single and split applications (SA) of UF on soil chemical properties, growth, and yield of maize. The treatment involved three levels of PM (0.0, 4.0, and 8.0 t·ha−1) and four sets of periods of UF: (i) 0 kg N ha-1 (control), (ii) 120 kg N ha-1 applied at planting (AP), (iii) two SA of 120 kg N ha−1 (90 kg N ha-1 applied AP + 30 kg N ha-1 at thirty days after planting (DAP)), and (iv) three SA of 120 kg N ha-1 (60 kg N ha-1 applied AP + 30 kg N ha-1 thirty DAP + 30 kg N ha-1 at tasseling). The 12 treatments were arranged in a randomized complete block design and replicated three times. PM and UF alone and integrating UF with PM improved soil chemical properties, growth, and yield of maize compared with the control. SA of UF three times (60 + 30 + 30) had the most improved soil chemical properties, growth, and yield of maize. Results also showed that maize yielded higher under UF integrated with PM compared with their sole forms. Application of 60 + 30+30 with 8 t ha−1PM (60 + 30+30 + 8 t ha−1PM) or with 4 t ha−1PM treatments showed the highest growth and yield of maize, but due to the bulkiness, handling challenges, and cost of PM, 60 + 30+30 + 4 t ha−1PM is recommended. Therefore, for better growth and yield of maize, after the initial application of PM, UF application should be split-applied in accordance with plant growth and the pattern of uptake to avoid losses by leaching and therefore ensured that N level in the soil is high at the critical stage of N demand.

An experiment was conducted at the research farm of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh, during November 2013 to April 2014 to determine the growth and yield performance of four varieties of black cumin (Exotic variety, BARI kalozira-1, Faridpur local and Natore local) as influenced by three levels of fertilizers (40-20-30 Kg ha-1, 80-30-45 Kg ha-1 and 120-40-60 Kg ha-1 N-P-K, respectively).  The experiment was conducted in a randomized complete block design (RCBD) with three replications. First flower bud initiation day, capsule setting, and capsule ripening in 50% plant were not significantly influenced by N-P-K fertilizer levels. The secondary branch plant-1, tertiary branch plant-1,plant height at harvest, capsule length, capsule diameter and 1000 seed weight of black cumin were also not influenced significantly by the fertilizer levels. The dry matter weight  plant-1, primary branch plant-1, fruit plant-1, seed capsule-1 and grain yield of black cumin genotypes were significantly influenced by different levels of N-P-K fertilizers. Natore local gave maximum dry matter  production plant-1  at 55 DAS with moderate  N-P-K levels and at 70 DAS with higher N-P-K fertilizer levels (0.22 and 1.06 g, respectively), whereas Exotic black cumin genotype showed maximum dry matter plant-1  at 85 and 100 DAS with higher N-P-K fertilizer levels  (2.30 and 4.97 g, respectively). Exotic variety produced maximum grain yield (3.43 g plant­­-1 and 2.30 t ha-1)  at higher level of N-P-K fertilizer, but BARI kalozira-1 (2.95 g plant­­-1  and 1.95 t ha-1), Faridpur local (2.80g plant­­-1  and 1.90 t ha-1) and Natore local (2.69 g plant­­-1  and 1.80 t ha-1) showed maximum yields at moderate N-P-K fertilizer levels. Among the test varieties of black cumin, the exotic variety showed better yield performance than the others.The Agriculturists 2015; 13(2) 97-104

Critical P eriod of W eed Control (CPWC) is the period in crop growth cycle during which w eeds must be controlled to prev ent unacceptable yield losses.T w o sets of treatments w ere imposed to represent both increasing duration of w eed interference and the length of the w eed-free period measured after germination. The first set of treatments consists of increasing duration of w eed interference by delaying w eed control from the time of crop emergence up to predetermined w eek (w eedy up to 2,4,6,8,10 and 12 w eeks after germination (W AG) of Kala Zeera ) . The second set of treatments established six lev els of increasing length of the w eed-free period (w eed free upto 2, 4, 6, 10 and 12 W AG). Besides tw o controls (W eed free and w eedy check). These comprised of 14 treatments which w ere laid out in randomized complete block design with three replication. It w as rev ealed that v ariation in Kala zeera seed yield due to w eeds is upto 88% and yield gets reduced as low as 48 % in w eedy check plots. Early w eed competition does not hav e hav e profound influence in Kala zeera crop.According to av erage data of tw o y ears inv estigation, it w as concluded that W eeds emerging betw een 6-12 W AG appear to be most detrimental to Kala zeera growth and yield and hence qualifies critical stage for w eed competition.

The present investigation was executed at Agricultural Research Field, Noakahali Science and Technology University, Noakhali, Bangladesh to access the effects of variety and integrated application of vermicompost, biochar and urea on efficiency of boro rice yield. The experiment was accomplished during the period from November 2018 to May 2019. It was completed in a randomized complete block design (RCBD) with three replications. The treatments assigned in a factorial arrangement of 2 × 4, with 2 varieties of rice (V1-BINA dhan 8, V2- BINA dhan 10) and 4 integration of vermicompost, biochar, and urea (T1: Vermicompost-2.5 t ha-1, T2: Vermicompost-2 t ha-1+ Biochar 0.5 t ha-1, T3: Vermicompost-1.5 t ha-1+ Biochar 1 t ha-1 and T4: Vermicompost-1.5 t ha-1 + Urea-150kg ha-1/0.15 t ha-1). Data were collected to analyze growth and yield contributing characters of boro rice. All the parameters were not statistically significant to differ. According to variety highest grain (3.73 t ha-1) and straw (2.8 t ha-1) yield was found from BINA dhan 10 in comparison with BINA dhan 8. In case of integrated application of vermicompost, biochar and urea, superior grain and straw yield were obtained from T4: Vermicompost-1.5 t ha-1 + Urea-0.15 t ha-1 whereas lowest grain yield (3.01 t ha-1 recorded from integrated application vermicompost and biochar. In combine maximum grain (4.92 t ha-1) and straw (4.40 t ha-1) yield was noted from BINA dhan 10 alone with integrated application of vermicompost and urea whereas the lowest data (grain: 2.50 t ha-1; straw: 1.64 t ha-1) was found from BINA dhan 8 along with vermicompost and biochar.

An experiment was conducted on farmer’s field in Khajura, Banke for site specific nutrient management (SSNM) in hybrid maize (Rajkumar) during winter season of 2016. The climatic condition of the experimental location was humid sub-tropical and sandy loam soil occurring intense summer and severe winter. Average annual rainfall of 1000 -1500 mm occurs in the location. The experiment was replicated 4 times in Randomized complete block design having plot size of 4.8 x 3 m2. Row to row spacing was maintained at 60 cm and plant to plant at 25 cm for each plot. There were six treatments including farmers fertilization practice (27.6:27.6:18 NP2O5K2O kgha-1) as a check, recommended dose of fertilizer (160:60:40 NP2O5K2O kgha-1), site specific nutrient management (212.9:66.8:280.8 NP2O5K2O kgha-1), 75% SSNM (372.6:116.9:491.4 NP2O5K2O kgha-1), FP-N, FP-P, SSNM-K (27.6:27.6:280.8 NP2O5K2O kgha-1) and SSNM-N, FP-P, FP-K (212.9:27.6:27.6 NP2O5K2O kgha-1). Among the treatment combination; application of SSNM we can increase the yield by 193% over farmer fertilization practice. Recommended dose of fertilizer and 75 percent SSNM also increase the yield by 138% and 130.4% respectively compared to farmer fertilization practice. 88% and 53.5% more increment could also be obtained through the application of only SSNM dose of nitrogen and SSNM dose of potassium respectively over farmer fertilization practice.
