Present research work conducted at the experimental field of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from November 2011 to April 2012 to study the feasibility of replacing chemical fertilizer by organic fertilizer in maize production. The experiment comprised of 10 treatments with organic manure and inorganic fertilizer viz., T0: Control (without any fertilizer), T1: All chemical fertilizers (recommended dose), T2: Cowdung (Recommended dose), T3: Compost (recommended dose), T4: ½ Compost + 1/2 Cowdung, T 5: Full cow dung + Full compost, T6: Full cow dung + 1/2 Chemical fertilizer, T7: Full compost + ½ Chemical fertilizer, T8: Full cow dung + Full compost + 1/2 Chemical fertilizer, T9: 1/2 Cowdung + 1/2 Compost + 1/2 Chemical fertilizer. Maize variety of BARI hybrid bhutta 9 was the test crop. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Results indicated that the highest cobs plant-1 (1.67), cob length (22.27 cm), cob diameter (14.12 cm), grains cob-1 (531.90), weight of 1000 grain (305.30 g), grain yield (11.75 t ha-1) and stover yield (13.97 t ha-1) was obtained from T1. Treatments T7, T8 and T9 gave statistically similar values in respect of yield and yield contributing characters. Treatment T9 (1/2 Cowdung + 1/2 Compost + 1/2 Chemical fertilizers) could be ideal fertilizer management for maize cultivation keeping chemical pollution minimum with improved soil condition and increased grain yield.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh from June to December 2015 to investigate the effect of spacing and fertilizer management on the yield of transplanted Aman rice cv. BRRI dhan39. The experiment comprised of five spacings viz. 25 × 5 cm, 25 × 10 cm, 25 × 15 cm, 25 × 20 cm, 25 × 25 cm and four fertilizer schedules viz. no manure and no fertilizer (control), recommended dose of inorganic fertilizer (80-60-40 kg N, P2 O5 , K2 O ha-1, respectively + 60 kg ha-1 gypsum + 10 kg ha-1 ZnSO4 ), 75% recommended dose of inorganic fertilizer + cow dung at 5 t ha-1, 75% recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha-1. The experiment was laid out in a Randomized Complete Block Design with three replications. Plant height (104.60 cm), number of total tillers hill-1 (11.03), panicle length (22.25 cm), grains panicle-1 (109.00) and grain yield (4.42 t ha-1) were found to be the highest in 25 × 15 cm spacing. Regarding nutrient management, 75% recommended dose of inorganic fertilizers + cow dung at 5 t ha-1 superseded other treatments in terms of plant height (107.50 cm), number of total tillers hill-1 (10.40), number of effective tillers hill-1 (7.68), panicle length (22.26 cm), grains panicle-1 (111.70) and grain yield (4.14 t ha-1). The control treatment (no manures and no fertilizers) gave the lowest values for all these parameters. The highest grain yield (4.57 t ha-1) was found in 25 × 15 cm spacing combined with 75% recommended dose of inorganic fertilizers + cow dung at 5 t ha-1 and the lowest grain yield (2.50 t ha-1) was found in 25 × 5 cm spacing combined with control (no manures and fertilizers). Therefore, 25 × 15 cm spacing combined with 75% recommended dose of inorganic fertilizers + cow dung at 5 t ha-1 appeared as the promising practice in transplant Aman rice cv. BRRI dhan39 cultivation.

Quantitative And Qualitative Traits

Due to the potential to enhance soil productivity and plant growth, biological fertilizers have recently been considered an alternative source for soil, water, and crop-contaminating chemical fertilizers in sustainable agriculture. The importance of different fertilizer sources on quantitative and qualitative traits of Syrian cephalaria (Cephalaria syriaca L.) was explored in an experiment based on a randomized complete block design during the 2015–2016 growing season. The maximum grain yield (9.97 g/plant) and biological yield (24.57 g/plant) were obtained from the application of Azotobacter + chemical fertilizer treatment, but the maximum oil percentage (25.23%) and oil yield (2.41 g/plant) were observed in the plants treated with Azotobacter + vermicompost. The plants treated with Azotobacter + chemical fertilizer exhibited the highest 1000 seed weight (15.03 g). Application of Azotobacter + vermicompost increased chlorophylls a, b, and total by 2.06, 1.96, and 4.02% versus Azotobacter treatment alone, respectively. The treatment of Azotobacter + manure increased total phenol, flavonoids, and DPPH antioxidant activity by 27.89, 0.56, and 53.16% versus the treatment of Azotobacter + chemical fertilizer. The integrated application of different fertilizer sources had an optimal effect on the uptake of trace elements (Cu, Fe, and Zn) so that the treatment of Azotobacter + vermicompost increased their concentrations. Due to the positive effect of integrated application of different fertilizer sources on improving the studied traits of Cephalaria, it is recommended to replace chemical fertilizers with combined fertilizers including organic and biological inputs to enhance the efficiency of crops, reduce environmental pollution, and move towards sustainable agriculture.

Organic fertilizer (OF) has positive effects on soil, especially soil fertility and productivity. Two experiments were conducted at the farmer’s field of Mymensingh and Jamalpur to observe the effect of organic fertilizer on cabbage production during rabi season 2018. There were seven fertilizer treatments viz: T1: RCF (N150 P40 K100 S16 Kg ha-1), T2: 85% RCF, T3: 70% RCF, T4: 85% RCF + 3 t ha-1 OF, T5: 85% RCF + 1 t ha-1 OF, T6: 70% RCF + 3 t ha-1 OF and T7: 70% RCF + 1 t ha-1 OF. The experiments were laid out in a RCBD (Randomized Complete Block Design) with three replications. The average fresh yield at Mymensingh ranged from 34.5 to 60.0 t ha-1 with the highest yield of 60.0 t ha-1 from treatment T4 (85% RCF + 3 t ha-1 OF). At Jamalpur, the average yield ranged from 31.5 to 56.3 t ha-1 and the highest yield of 56.3 t ha-1 was recorded from treatment T4 (85% RCF + 3 t ha-1 OF). The lowest yield was found from treatment T3 in both locations. The percent fresh yield increased over control (T1), was 42.85 and 40.04 in Mymensingh and Jamalpur, respectively. The highest gross margin is Tk. 534507, which was obtained from treatment T4 (85% RCF + 3 t ha-1 organic fertilizer). The highest MBCR 3.05 (average of two locations) was obtained from the same treatment T4 (85% RCF + 1 t ha-1 organic fertilizer). The result indicated that applying organic fertilizer and 85% recommended dose of chemical fertilizer is more profitable than applying chemical fertilizers only.

Tomato is one of the most demanded vegetable with increasing trend of commercial cultivation in Nepal. As it is the heavy feeder crop thus soil nutrient management has been always challenging. Since, in modern world organic production has been favored by consumers for many reasons thus we aimed to compare the efficacy of various compost, mineral fertilizers and their combinations in tomato production and soil productivity. For the purpose a field experiment in plastic tunnel was carried out in Horticulture Research Division, Khumaltar in two consecutive years (2014 and 2015). Srijana, a popular tomato hybrid among commercial producers, was purposively selected. Eight treatments (control, recommended doses of chemical fertilizers, compost 15 t ha-1 + cattle urine, compost 10 t ha-1 + cattle urine, compost 12.5 t ha-1 + cattle urine, compost 15 t ha-1 + 1/4 recommended dose of chemical fertilizers, compost 10 t ha-1 + ¾ recommended dose of chemical fertilizer and compost 12.5 t ha-1 + 1/2 recommended dose of chemical fertilizer) were laid out in randomized complete block design and replicated thrice. The result showed significant (p < 0.05) positive correlation between the plant height and yield of tomato. The treatment with compost dose of 12.5 t ha-1 with half dose of recommended dose of chemical fertilizers produced the highest incremental yield (85% increment) over other treatments followed by compost 15 t ha-1 with cattle urine. Addition of soil organic carbon, soil nitrogen, soil potassium by the increasing level of compost though not significant, but increment in carbon content, nitrogen content and potassium content of soil observed in successive years. For commercial producer at plastic tunnel, compost at the rate 12.5 t ha-1 with half dose of recommended level of chemical fertilizer (100:90:40 kg N:P:K ha-1) is recommended to apply in field, while for organic producer, application of 15 tha-1 compost with fermented cattle urine is recommended.

<p>The main objectives of this research were to determine the effects of applying organic and chemical fertilizers under different irrigation regimes on sunflower (<em>Helianthus annuus</em> L.) morphological traits, yield components, grain yield and grain quality. The experiment was conducted as spilt plots based on a randomized complete block design with three replicates. Irrigation treatments at three levels (well-irrigated, mild and severe drought stress) were allocated to main plots and eight fertilizer treatments (urea (F1), urea + composted cattle manure (F2), zeocompost (F3), vermicompost (F4), zeolite-amended chicken manure (Z-ACM) (F5), zeocompost + vermicompost (F6), zeocompost + Z-ACM (F7) and vermicompost + Z-ACM (F8)) were randomized in sub-plots. The results showed that irrespective of the drought stress intensity, organic fertilizer treatments produced more dry matter, heavier and greater grain than did chemical treatments. In well-irrigated plots, the highest grain yield was obtained from F6, F7 and F8 treatments. Under drought stress conditions, the highest grain yield was obtained from the high zeolite content organic fertilizers i.e. F3, F5 and F7. We concluded that amending soil with organic fertilizers in combination with zeolite<em> </em>can be a beneficial approach for decreasing chemical fertilizer application rates and improving the sustainability of agricultural systems.</p>

An experiment was conducted to evaluate the yield performance of potato varieties with chemical and organic fertilizer at Chilime, Rasuwa. The experiment consisted of eight treatment combinations laid out in two factors Randomized Complete Block Design (RCBD) with three replications. Four potato varieties (Khumal-Seto-1, Khumal-Ujjwal, Janak-Dev and Kufri-Jyoti) with fertilizer (Recommended dose of chemical fertilizer (100:100:60 NPK kg ha-1) and organic farmyard manure (15 mt ha-1) were used to make eight treatment combinations. The results showed that Janak-Dev had the highest plant height (69.3 cm) and canopy diameter (60.92 cm). Khumal-Seto-1 had highest number of main stems per hill (3.75) which were statistically similar to Kufri-Jyoti (3.42) and Khumal-Ujjwal (3.25). Janak-Dev had the lowest number of main stems per hill (1.87). The effect of fertilizer was nonsignificant. Flowering occurred earlier in Janak-Dev at 61.17 days after sowing while Kufri-Jyoti flowered after 73.17 days after sowing. The highest number of tubers were found in Khumal-Seto-1 (9.167) and lowest in Janak-Dev (5.750). Number of tubers per plant was not affected by types of fertilizers used. Maximum weight of each tuber (107.7 grams), yield per plant (780 grams) and yield per hectare (37.1 mt ha-1) were obtained from Kufri-Jyoti. These parameters were the highest from chemical fertilizer application. This field experiment showed that Kufri-Jyoti with recommended dose of chemical fertilizer was appropriate to get optimum yield under Chilime condition. SAARC J. Agric., 19(1): 103-112 (2021)

Combined Application

Dried Albizia leaf mould (10 mt/ha) and banana peel (0.1-0.5 mt/ha) with reduced level of NP chemical fertilizers were applied on the production of okra (Abelmoschus esculentus L.).The experiment was carried out in a randomized complete block design with seven treatments. The result revealed that the combined application of 10 mt/ha leaf mould and 0.1 mt/ha banana peel with 50% NP chemical fertilizer as basal and 50% N as top dressing (T6) exhibited higher yield than recommended 100% NPK chemical fertilizer alone (T2). Plants treated with fertilizers showed significant influences (P<0.05) in the growth parameters such as leaf area, length, fresh and dry weight among treatments. Remarkable differences (P>0.05) in number of fruits per plant were obtained. Among the treatments, considerable variations in fruit diameter, fresh and dry weight of fruit (P<0.05) were observed. An increase in the fresh weight of fruit per plant by approximately 8.5% was obtained in T6 when compared with the control (T2). The marketable fruit yield per m2 was 654.71 g in T6 and 603.61 g in the control. It was also noted that combined use of organic (leaf mould with banana peel) and chemical fertilizers increased fruit yield when compared to the application of organic fertilizer (leaf mould with banana peel) alone as basal application. From this study, it could be concluded that Albizialeaf mould (10 mt/ha) and banana peel (0.1 mt/ha) with 50% NP chemical fertilizers as basal and also 50% N chemical fertilizer as top dressing could be used for obtaining high fruit yield in okra cultivation.
