An experiment was conducted at the experimental farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during December 2009 to March 2010 to study the effect of household wastes compost, palli compost and quick compost on growth and yield of red amaranth and spinach and improvement of soil fertility. The first time red amaranth and spinach were grown using compost and inorganic fertilizers, while the second time crops grown using only residual nutrients in soil. Yield data revealed that combined application of organic and inorganic fertilizers were significantly better than the solitary application of inorganic fertilizers. The fresh yield of red amaranth in the second harvest where no fertilizers were used recorded 13 t ha-1, which appeared significantly higher over the first harvest (10 t ha-1) and there was no significant difference between the yields of first and second harvest of spinach (18 t ha-1). Different composts increased OM, N, P and K contents, which indicated the fertility improvement of soil. The performance of composts at the rate of 20 t ha-1 in producing yields of vegetables was insignificantly different with the rates of 5-10 t ha-1. Among the different composts, household waste is available in the rural areas and its preparation is easy with minimum costs. Therefore, considering the availability and costing, household waste compost at the rate of 5-10 t ha-1 is recommended as a soil amendment for improving soil fertility and crop productivity.

The present study was carried out to assess the existing status of compost usage on vegetable production and determine the overall effect of household waste compost (HWC) on growth and yield of vegetables and enhancement of soil fertility in the monga areas of Bangladesh. A field survey was conducted on 152 sampled farmers during 2010 to 2011. Questionnaire containing both closed and open-ended questions were used to assess existing production practices of vegetables using compost in both homestead and field conditions. Three field trials at Badargonj and Kawnia upazilas of Rangpur district were conducted taking four treatments i.e. control, recommended doses (RD) of fertilizers, HWC at the rate of 10 tha-1, and HWC 10 t ha-1 plus RD as IPNS based with Lal shak, Palong shak, Pui shak and Tomato. Base line survey results indicated inadequate knowledge of the farmers on use and preparation of the household waste compost. Yield data of all vegetables i.e. Tomato, Lal shak, Palong shak and Pui shak indicated that the combined application of nutrients using organic and inorganic sources were significantly better than that of solitary application of inorganic fertilizers. The potential of household waste compost applied @ 10 t ha-1 along with inorganic fertilizers applied was found highly satisfactory in producing Tomato, where yield was recorded 75 t ha-1 in the study area. The fresh yield of Palong shak was found 16 t ha-1 when recommended doses of inorganic fertilizers were applied, but it was about 19 t ha-1 under combined application of HWC @ 10 t ha-1 and inorganic fertilizers following IPNS concept. The fresh yield of Pui shak was found about 49 t ha-1 under combined application of organic and inorganic nutrients. Considering the availability and costs of different composts, it is evinced that HWC contained good amount of NPK which indicates its potentiality to be used as a soil amendment, improving soil fertility and crop productivity. It can be an alternative to chemical fertilizer to increase soil microbial populations and enzyme activities and to promote the soil nutrient for horticultural crops in the unfertile areas especially in the monga areas of Bangladesh.

Organic And Inorganic Fertilizers

Soil fertility and maximum crop production can only be achieved through proper fertilization. Proper and balanced fertilization have a considerably positive effect on plant growth and yield. Due to continuous use of chemical fertilizers, the organic matter and nutrient content of the soil decreased gradually. Therefore, in modern era, agriculture scientists are now engaged to establish an agricultural system, which can not only lower the production cost, but also conserve the natural resources. Soil, as a source of nutrients, must be protected from various kinds of external factors, especially from the addition of fertilizers in excessive rates. Any degradation in the quality of soil can significantly produce many undesirable changes in the environment and also reduces the overall crop yield. So, the concoction of organic and inorganic fertilization is an alternative and most effective method for sustainable and cost-effective management for maximum crop production, without effecting the environment. The Integrated Nutrient Management provides an excellent opportunity not only for sustainability of the soil, but also enhances the overall crop productivity. The present review study was carried out with the main aim to evaluate the role of combined application of organic and inorganic fertilizers on wheat crop production. The outcome of the study concluded that combined application of both organic and inorganic fertilizers significantly improve the wheat crop production, as compared with the sole application of either organic or inorganic fertilizers.

Most farmers’ practices broadcast sowing methods and productivity is less. Soil fertility maintenance is a major concern in tropical Africa which needs to tackle soil fertility depletion as a fundamental constraint. Similarly, the traditional way of planting tef reduces the amount of grain production, promotes competition for inputs, and causes severe lodging. This paper aimed to review the interaction effects between seed sowing methods and different types of inorganic fertilizers on the growth and yield of teff. In Ethiopia, recent research indicates planting method (row planting and broadcasting) affects the yield and yield components of teff. The review indicates the yield components include heading and maturity, plant height, first growth rate, number of tiller and panicle, thousand seed weight, grain, straw, and total biomass yields and harvest index high in Method of Row sowing compared to broadcast in Ethiopia but Days to emergence and panicle length were more affected by broadcasting. In economical acceptance, Row sowing was found to be economically acceptable with more income from grain yield than broadcasting.

To evaluate the effects of integrated nutrient management on growth and yield of BARI tomato-14 and soil fertility, a pot experiment was conducted in the net house of the department of Agricultural Chemistry of Bangladesh Agricultural University, Mymensingh during the period from October 2011 to April 2012. The experiment was laid out in a completely randomized design with 11 treatments and 3 replications. Treatments were control, RDCF100, 75% RDCF, 50% RDCF, 75% RDCF + PM2 t /ha, 75% RDCF + RS3 t /ha, 75% RDCF + PHRD, 50% RDCF + PM3 t /ha, 50% RDCF + RS5 t /ha, 50% RDCF + PHRD, PM3 t /ha + RS5 t /ha + PHRD. Among the treatments applied in combination of PM2 t /ha+ 75% of RDCF excelled in growth trends of morphological characters like plant height, number of branches plant- 1, number of leaves plant-1; available soil P and S. But sole application of RDCF100 recorded higher values for almost all morphological characters namely number of branches plant-1, number of leaves plant-1, fruit diameter, fruit weight plant-1 and yield of tomato following the same trend as seen in combined application of CF and PM. Among the plant hormone applied in combination, RDCF75% + PHRD showed the highest plant height. The more number of leaves plant-1, number of branches plant-1, yield and yield parameters as compared to other treatments were also significantly influenced by application of PH. Combined application of 50% of RDCF+RS5 t /ha increased exchangeable soil K. PM3 t /ha+ RS5 t /ha+ PHRD conserved more organic carbon and total soil N. Results showed that the integrated use of PM, RS along with CF increased the availability of nutrients throughout the growth period by maintaining the long term productivity for sustainable production of tomato.

The utilization of organic fertilizers in farmlands to enhance crop productivity and soil health is increasing globally. Compost and charcoal obtained from the decomposition and slow pyrolysis (respectively) of plants and animals wastes. Here we evaluated the effect of charcoal and compost on the growth and yield of wheat (Triticum aestivum L.) at Agriculture Research Farm Peshawar, Pakistan during 2014-2015. Results showed that the application of compost and charcoal as sole or in combination significantly affected the yield and yield attributes of wheat. Data divulged that the maximum numbers of plant tillers (337 m-2), number of productive tillers per plant (313 m-2), number of grains per spike (56 spike-1) and 1000 seeds weight (50.2 g) were produced by the combined application of compost and charcoal at 5+5 Mg ha-1 while plant height (95.3 cm) was enhanced with the application of charcoal at 10 Mg ha-1. The gain (4106.7 kg ha-1) and biological yield (8473.3 kg ha-1) was significantly increased with the compost application at the rate of 10 Mg ha-1. These results proved that charcoal and compost can be used as organic fertilizers for boosting growth and yield performance of wheat under the agro-climatic conditions of Peshawar, Pakistan.

The main goal is to investigate the effect of crop nutrient management on growth and yield of two tomato varieties in the Chittagong Hill Tracts (CHTs) region of Bangladesh. Two factors experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Factor A was two varieties of tomato namely, V1: BARI 2 and V2: BARI 15. Factor B was different types of fertilizer like F0 (Farmers practices), F1 (vermicompost), F2 (inorganic fertilizer), F3 (combined fertilizer: 3/4 vermicompost+ 1/4 inorganic fertilizers), F4 (control, no fertilizer). Soil characteristics and climatic conditions were recorded. Plant growth, flowering and fruit characters, and yield were found significantly different (p<0.05).  The highest plant height, flowering and fruit characters related to higher production were found in BARI 15 (V2) variety influenced by combined application of fertilizer F3 (3/4 vermicompost + 1/4 inorganic fertilizers). The maximum number of flower clusters per plant (9.66), fruit clusters per plant (8.13), individual fruit weight (117.7 g), fruit numbers per plant (51.17) were found in V2F3 and the same parameters were the lowest in V1F4. The results showed the highest production (95.50 t/ha) in V2F3 followed by V2F0 (81.70 t/ha), V2F1 (72.17 t/ha) and V2F2 (68.06 t/ha), and the lowest yield (27.70 t/ha) in V1F4. The highest fruit yield ((95.50 t/ha) found in V2F3 showed 80.84% higher compared to the V1F4 (27.70 t/ha) treatment. Considering the variety, the highest yield (74.05 t/ha) was found in V2 which was 40% higher yield compared to V1. Combined application of vermicompost and inorganic fertilizers performed best as the nutrient management and BARI 15 was found as a suitable variety for the CHTs climatic condition. Hence, the similar type fertilizers proportion can be applied for the other vegetables production in the farmers field for the healthy and eco-friendly environment achievement.

A field experiment was conducted at Nalanda College of Horticulture, Noorsarai, Nalanda during summer 2017 to assess the effect of complementary and sole applications of organic and inorganic fertilizers on the growth and yield of bottle gourd under onion-onion-bottle gourd crop sequence. The experiment consists of seven treatments viz.,T1-Inorganic fertilizers (120 Kg N: 60 Kg P2O5 and 40 Kg K2O); T2-50% NPK through inorganic fertilizer + 50%N through FYM; T3-50% N through FYM + 50% N through VC; T4-1/3 of N through FYM + VC + Neemcake; T5-50% N through FYM + PSB + Azotobactor; T6-T3 + PSB + Azotobactor and T7-T4 + PSB + Azotobactor. These seven treatments were replicated thrice in Randomized Block Design. Results revealed that T1-100% NPK through inorganic fertilizer recorded 225.7 q ha-1 fruit yield, which was statistically at par with T2 and T6 producing (211.8 and 209.5 q ha-1). Vine length differed significantly at all the growth stages. T1 recorded maximum vine length (51.8, 370.3 and 464.7 cm) at 30, 60 and 90 DAS, which was significantly higher over T5 at 30 DAS, over T4 and T5 at 60 DAS and over T5 at 90 DAS. Among organics, T6 recorded longest vine, while T5 recorded shortest. No. of branches were found non-significant at 30 DAS but it become significant at 60 and 90 DAS and found significantly highest in T6 over all the treatments. After completion of the cropping system; onion-onion-bottle gourd, soils were subjected to analysis. pH differed significantly, while non-significant difference were observed in EC and soil Org-C. Similarly, available N and P concentration were also found non-significant due to different fertilizer sources, but the concentration of available K differed significantly and found highest in T1 which was at par with T2. T1-100% inorganic fertilizer sources recorded highest gross return, net return and B: C ratio followed by T2. On the basis of result it has been concluded that T2 having 50% NPK through inorganic fertilizer + 50% N through FYM may found suitable for sustainable bottle gourd production as it performed at par with T1 in respect to crop growth and yield.

Growing vegetable crops such as lettuce, on Ultisol soil has several obstacles, such as insufficient organic matter and nutrients in the soil. The provision of biochar and POC leri or organic fertilizer from rice washing liquid is expected to be a long-term and sustainable solution. This study was intended to test the addition of biochar to the growing media and the application of leri on lettuce cultivation. This study used a factorial Randomized Block Design (RAK) method. The first factor was the application of biochar to the planting medium (M), which consisted of M1: Ultisol without biochar and M2: Ultisol + 30 g biochar. The second factor was the administration of liquid organic fertilizer (LOF) leri (P), with 5 treatments consisting of P0: without giving LOF leri, P1: giving LOF leri without fermentation once a week, P2: giving LOF leri without fermentation twice a week, P3: giving fermented LOF leri once a week, P4: giving fermented LOF leri twice a week. The results of this study were tested statistically by analysis of variance, with the F test; if there was a significant difference, it was continued with the BNJ test (Honest Significant Difference) at a 0.05 level. The results showed that the best treatment of LOF leri in increasing lettuce growth and yield was 25% fermented LOF leri given 2 times a week, at 250 mL per lettuce plant. As a single treatment the best growing media was M2 (Ultisol soil + 30 g of biochar) with a plant height of 25.80 cm and the leaf number of 12.83; whereas the best LOF leri treatment was P4 (fermented LOF leri given twice a week), with a plant height of 30.27 cm and leaf number of 14.42. Based on whole plant fresh weight, the best treatment was the M2P4 (Ultisol + biochar growing medium and fermented LOF leri given week), which was 185.99 g per plant.

Soil Fertility Status

Soil fertility management in agricultural land is challenging in hilly areas of Nepal. The study assesses the soil fertility status of Bari (upland) and Khet (lowland) agriculture land in Mid-hill of Gorkha district. Altogether 30 samples were collected from soil surface (0 to 20 cm) by using hand shovel in January, 2017. The soil fertility parameters like pH, organic matter (OM), total nitrogen (TN), available phosphorus (P) and available potassium (K) were analyzed using standard methods in the laboratory of Central Department of Environmental Science, Tribhuvan University. Results revealed that an average pH in upland (6.62) was higher than the lowland (5.94). Similarly, OM (3.95%) and K (36.49 kgha-1) were relatively high in upland. In addition, pH, OM and available K were significantly varied at p<0.05 in upland and lowland soils, however, there is no significant difference in TN and available P. In addition, soil nutrient index showed that status of available K in both types of land is low, while OM and TN are medium soil quality in upland and lowland soil. The use of organic fertilizer and improved farming system can maintain and sustain soil fertility for crop growth and yield. Understanding distribution of soil nutrients in the study area might be useful for planners to make effective soil fertilizer management strategies.

Salinity stress is a severe environmental stress that affects plant growth and productivity of potato, a strategic crop moderately sensitive to saline soils. Limited studies are available on the use of combined nano-micronutrients to ameliorate salinity stress in potato plants (Solanum tuberosum L.). Two open field experiments were conducted in salt-affected sandy soil to investigate plant growth, physiology, and yield of potato in response to soil salinity stress under single or combined application of Zn, B, Si, and Zeolite nanoparticles. It was hypothesized that soil application of nanoparticles enhanced plant growth and yield by alleviating the adverse impact of soil salinity. In general, all the nano-treatments applications significantly increased plant height, shoot dry weight, number of stems per plant, leaf relative water content, leaf photosynthetic rate, leaf stomatal conductance, chlorophyll content, and tuber yield, as compared to the untreated control. Furthermore, soil application of these treatments increased the concentration of nutrients (N, P, K, Ca, Zn, and B) in plant tissues, leaf proline, and leaf gibberellic acid hormone (GA3) in addition to contents of protein, carbohydrates, and antioxidant enzymes (polyphenol oxidase (PPO) and peroxidase (POD) in tubers. Compared to other treatments, the combined application of nanoparticles showed the highest plant growth, physiological parameters, endogenous elements (N, P, K, Ca, Zn, and B) and the lowest concentration of leaf abscisic acid (ABA) and transpiration rate. The present findings suggest that soil addition of the aforementioned nanoparticles can be a promising approach to improving crop productivity in salt-affected soils.
