Effects of Different Sources of Fertilizers on Growth and Yield of Radish (Raphanus sativus L.)

Radish is a widely cultivated root crop susceptible to chemicals for its growth and development. The experiment was conducted to study the effect of different sources of organic fertilizers on growth and yield parameters in the Tokinashi variety of radish. The experiment was laid out using one factorial completely randomized block design with six treatments replicated four times. Vermicompost, goat manure, chemical fertilizers (NPK), poultry manure, farmyard manure and control were the applied treatments. Various growth and yield parameters of radish were measured and assessed at 15-day intervals. Various growth and yield parameters of radish were measured and assessed at 15-day intervals. Growth parameters were observed at 15, 30, 45, and 60 days after sowing. For yield parameters, destructive samples were taken and observed at 30 DAS and 45 DAS and harvested at 60 DAS. The assessments of plant growth and yield parameters showed that poultry manure (PM) treatments were superior. At the time of harvesting, the treatment comprising poultry manure had considerably greater plant height (30.55 cm), leaf length (29.44cm), leaf breadth (10.78cm), leaf number per plant (9.23), root diameter (10.33cm) and root length (20.16cm) with superior yield per ha (33.59 mt ha-1). Poultry manure significantly enhanced root yield and was positively correlated with all growth parameters. The highest benefit-cost (B: C) ratio was recorded in chemical fertilizer (3.99), which was statistically at par with poultry manure (3.81), suggesting that poultry manure might potentially replace chemical fertilizers for the Tokinashi variety of radish cultivation.

Production and quality of watermelon fruits (Citrullus lanatus) in response to different sources of fertilization

The objective of this work was to evaluate the production and quality of watermelon fruits in response to different sources of fertilization in the municipality of Humaitá (AM). The experimental design used was a randomized block design with three replications. The treatments were: T1 – without fertilization (control), T2 – 20 ton. ha-1 of cattle manure, T3 – 10 ton.ha-1 of vegetable ashes, T4 – 10 ton.ha-1 chicken manure, T5 – 10 ton.ha-1 of açaí kernels and T6 – liming and mineral fertilizer with NPK. Fruit quality and yield attributes were evaluated, such as number of fruits, yield, total soluble solids (°Brix) and titratable acidity. All treatments differed statistically in yield and quality, in relation to soil without fertilization. The T6 treatment provided higher productivity and higher levels of total soluble solids of commercial fruits. It was demonstrated that the type of fertilizer, if used in the right way, can improve the general quality of watermelon fruits and improve the crop’s production system. In the cultivation of watermelon, several sources of organic fertilizer can be used, such as manure from cattle, sheep, goats or poultry, which recommends future tests with supplementation of mineral fertilizer.

Effect of Different Sources of Fertilization on Chemical Properties of Soil Under Cassava Cultivation in Western Pará, Brazil

Nutrient management becomes essential in soils with low natural fertility, so the use of organic fertilizers can improve chemical properties of soil and reduce production costs. The objective of this study was to evaluate the effect of different fertilization sources on the chemical properties of soil under cassava cultivation. The experiment was conducted between 2017/2018 in the community of Boa Esperança, Santarém-PA using the cultivar Bem-te-vi, in the randomized block design with 4 treatments: T1 (without fertilization), T2 (fertilization NPK), T3 (organic fertilization with poultry manure), T4 (fertilization with cattle manure), with 5 replicates. The soil samples were analyzed for the contents K+, Ca²+, pH in H2O and KCl, Al³+ and soil organic carbon content (TOC). The data were submitted to analysis of variance and the means were compared by the Tukey test at 5% probability, using the software MINITAB© version 18. There were statistical differences between the treatments for all the chemical properties analyzed. The findings of the analysis were that fertilization with catle manure and NPK were the same and differed from the other treatments for the contents of K+, pH in H2O and KCl, for Ca²+ and TOC. The treatment without fertilization obtained the lowest values differing from the others, for Al³+. The source from NPK obtained the lowest content in the soil. The treatments with organic fertilizers had higher levels of the above nutrients in the soil. The chemical properties of the soil were altered from the different management systems for the cultivation of cassava.

O objetivo com este trabalho foi avaliar diferentes fontes de adubação no crescimento da planta, acúmulo de nutrientes nas folhas de Justicia pectoralis Jacq. visando ao aprimoramento na produção de biomassa. Os tratamentos consistiram de três diferentes adubações: orgânica, química e organomineral, mais a testemunha (sem adubação), dispostos num delineamento em blocos casualizados, com 18 repetições por tratamento em quatro blocos. Aos 100, 120, 150 e 180 dias após o transplante foram determinadas a altura e diâmetro. Na última avaliação as plantas foram colhidas manualmente. Avaliou-se a biomassa da parte aérea (g) e o teor de nutrientes foliares. Os dados obtidos foram submetidos a análise de variância. A análise de regressão foi utilizada para os dados biométricos das plantas e para a concentração mineral as médias foram comparadas pelo teste de Tukey (p<0,05). Houve influência positiva das diferentes adubações sobre o crescimento da planta em altura, diâmetro e biomassa seca, sendo que a adubação organomineral proporcionou maior desenvolvimento da planta. As plantas de J. pectoralis apresentam diferentes teores de nutrientes em seus tecidos foliares, com a seguinte ordem de acúmulo para os macronutrientes (g Kg-1): N > Ca > K > Mg > P > S; e para os micronutrientes (mg Kg-1): Fe > B > Mn > Zn > Cu. Por se tratar de uma planta com diversidade de metabólitos secundários e pertencentes à flora do Bioma Cerrado, ainda são necessárias pesquisas científicas que possibilitem a produção em escale evitando o extrativismo e perda de material genético.

Eficiência de substratos orgânicos no desenvolvimento do Manjericão (Ocimum basilicum L.)

O manjericão, planta herbácea anual de nome científico Ocimum basilicum L. pertencente à família Lamiaceae é planta produtora de óleos essenciais, amplamente utilizados. No Brasil, as folhas são cultivadas e comercializadas, podendo ser utilizadas in natura, frescas ou secas como condimento ou como aromatizante. Seu cultivo constitui uma alternativa geradora de emprego e renda para pequenos agricultores. Visto que a cultura do manjericão tem crescido proporcionalmente no mercado e que o cultivo em diferentes fontes de adubação em ambiente protegido, proporciona ganhos expressivos na produção, esta pesquisa teve como objetivo avaliar a eficiência de substratos orgânicos no desenvolvimento de manjericão (Ocimum basilicum L.).

Losses of water, soil, and nutrients during high-intensity simulated rainfall in two soil management systems different sources of fertilization

ABSTRACT: The goal of this study was to quantify the water, soil, and soluble nutrient losses during high-intensity rainfall simulated in two soil preparation systems with four sources of fertilization. Forty-five days after the corn seeding, a 120 mm h-1 intensity rainfall was simulated during 90 min in field plots with conventional tillage (CT) or no-tillage (NT). Each system had four repetitions with the fertilizer treatments, including without fertilization, mineral, urban waste compost (UWC), and pig slurry. P, K, Ca, and K concentrations were measured in soluble form, in addition to electrical conductivity, pH, water, and soil losses. As expected, the greatest soil losses occurred with CT; however, the greatest water losses occurred with NT. Among the fertilizers, UWC was more efficient because it had the highest infiltration rates. The concentrations of P, K, Ca, and Mg did not exhibit any interaction between fertilization and soil tillage treatments. K was the nutrient that presented the greatest losses (kg ha-1) at the end of the simulated rainfall because of the highest concentrations (mg L-1) added to high runoff coefficients of 45% for CT and 77% for NT. Thus, the evaluated system with cover crops and minimum soil tillage was not sufficient to control nutrient transfer in the soluble form during intense rainfall events.

Morphological and physiological performance of PSB Rc18 lowland rice (Oryza sativa L.) grown at different water, spacing and nutrient management

Rice yield fluctuates because of environmental influences on morphological and physiological processes, as well as inadequate human intervention, to stabilize crop productivity. A field experiment was conducted in two cropping seasons at the experimental area of the Department of Agronomy, Visayas State University, Baybay, Leyte to evaluate the morphological and physiological performance of lowland rice grown at different water, spacing and nutrient management. Different sources of fertilizers were designated as the mainplot and plant spacing as the subplot nested within two water regimes, ie, continuous flooding and no flooding. Lowland rice s under no flooding were shorter than those under plant continuous flooding. No flooding gave higher root pulling resistance, crop growth rate, net assimilation rate, leaf area index and harvest index and consequently produced higher grain yield of PSB Rc18. No flooding and continuous flooding water management resulted in the formation of aerenchyma cells in roots of rice plants which had statistically similar cell number and measurement. Wider spacing of 40cmx40cm gave the highest RPR. Water, spacing and nutrient management did not influence the phyllochron and total number of leaves on the main culm of PSB Rc18. However, PSB Rc18 at early growth stages tended to have longer phyllochron because of transplanting shock. No flooding, application of composted goat manure and closer spacing of 20cmx20cm is the best treatment combination that g ve similar yield to rice plants a applied with inorganic fertilizer at the rate of 90-30-30kg ha-1 N, P2O5, K2O.

Physalis cultivation can be an alternative of extra income for small and medium producers, mainly with the use of materials available on the property that can replace chemical fertilizer. This study aimed to evaluate agronomic parameters of Physalis peruviana and P. pubescens submitted two different sources of fertilization - chemical and organic. We evaluated plant height, shoot dry mass, production/plant, fruits diameter and weight and productivity. The organic fertilization provided better results for vegetative parameters. Regarding production, fertilization resulted in increase in mass, with no significant difference between sources. In the production of fruits/plant we obtained 156.2 g, 274.6 and 355.5 g for unfertilized, chemical and organic fertilizers, respectively, without significant differences between species. The productivity estimates were 2,370, 1,831 and 1,041 kg ha-1, for organic, mineral and unfertilized treatments, respectively. These results demonstrate that organic fertilizer with poultry manure is the best alternative as a source of nutrients, which may result in gains to the producer by the use of originated waste from other activities, as well as lower environmental contamination, either by improper disposal of waste or the use of chemical fertilizers.

Sustainable Production of Cabbage Using Different Irrigation Levels and Fertilizer Types Affecting Some Soil Chemical Characteristics

A field experiment was carried out during the two successive autumn seasons of 2013 and 2014 under open field conditions in protected cultivation site, Agriculture Research Centre , Giza governorate, Egypt. The study was investigating the effects of different irrigation levels (50, 75 and 100% of crop evapotranspiration (ETc)) and different sources of fertilizers (inorganic fertilizers (control), cattle manure, compost and vermicomp ost) on some soil chemical characteristics and vegetative growth, yield and water use efficiency of head cabbage. Obtained results showed that soil pH decreased at the end of experiment with a range of 0.08 - 0.30, compared with before cultivation, with high decreases by 50% of ETc combined with vermicompost. EC e , on the other hand, increased due to different agricultural activities such as adding chemicals and fertilizers, with

Yield and Quality Response of Ryegrass, Egyptian Clover and Their Mixtures to Different Sources of Fertilizers

Two field experiments were conducted during two successive winter seasons of 2008/2009 and 2009/2010 to investigate the potentialities of mixing Egyptian clover with ryegrass under bio, organic and mineral fertilization treatments and their combination to increase forage yield and quality grown under sandy soil conditions. The experiment included the combination of five mixing ratios (Egyptian clover alone, ryegrass alone, 75% Egyptian clover: 25% ryegrass, 50% Egyptian clover: 50% ryegrass and 25% Egyptian clover: 75% ryegrass) and eight fertilizer sources, which include control, organic fertilization, bio fertilization, chemical fertilizer, organic + bio fertilizer, organic + chemical fertilizer, bio + chemical fertilizer and combination of organic and chemical and bio fertilizers. The obtained results indicate the superiority of 75% E. clover: 25% ryegrass mixture fertilizedby Bio + O + N in fresh and dry forage production. On the other hand, it reported the lowest dry weight of weeds g/m2. Chemical analysis of forage plants showed that the mixture of 75% E. clover: 25% ryegrass surpassed that of other treatments yield for crude protein, ether extract and ash. The results also revealed that the highest record of DCP, crude fiber and TDNY was obtained by forage mixture of 75% E. clover: 25% ryegrass fertilized with Bio + O + N. Such higher yield of these characters hassecured a balanced ratio which is really needed for ruminants ration.

Effect of fertigation on growth and yield of summer tomato (Lycopersicon esculentum) using different rates and sources of fertilizers

A field experiment was conducted to study the effect of fertigation on yield of summer tomato (Lycopersicon esculentum Mill. noun. cons). The total seven treatments comprising of varying rates and different sources of fertilizers were applied. Application of 50% of N:P:K fertigation of 70% of the recommended dose gave higher plant height (62.7 cm) and number of branches (10.2). In general treatments receiving the fertigation had taken less number of days for flowering and fruiting over the conventional soil application of fertilizers. All the fertigation treatments recorded higher marketable tomato yield over the conventional soil application of fertilizers to the tune of 10.75 to 20.69%. Among fertigation treatments application of common N: K fertilizers at 50% of recommended dose through fertigation and the other 50% as soil application and water soluble fertilizers at 70% of recommended dosages resulted in higher marketable fruit yields. The highest net income (₹104 420) and B:C ratio (0.88) was obtained with the treatment received 50% of recommended dose of N:K using common fertilizers supplied through fertigation.

Response of Tuberose to Integrated Nutrient Management

A field experiment was conducted at the farmer’s field of Sutiakhali, Mymensingh Sadar Upazilla, Mymensingh, during the period from April, 2009 to March, 2010 to investigate the effect of organic fertilizers along with half chemical fertilizers on the growth, bulb and flower yield of tuberose cv. single. The experiment consisted of four different sources of fertilizers viz., (i) recommended chemical fertilizers @ 400, 300, 300 and 100 kg ha-1 of urea, TSP, MP and gypsum, respectively; (ii) vermicompost @ 5 t ha-1 along with half of chemical fertilizers; (iii) poultry litter @ 20 t ha-1 along with half of chemical fertilizers and (iv) cowdung @ 20 t ha-1 along with half of chemical fertilizers. The experiment was laid out in a randomized complete block design with three replications. Results revealed that plant height, leaf number plant-1, leaf length and breadth and number of side shoots plant-1, bulb production plant-1, bulb length, bulb diameter and bulb yield both per plant and per hectare, rachis length, spike length and diameter, number of florets spike-1 and flower yield both per spike and per hectare were greater in organic fertilizers along with half chemical fertilizers than absolute use of chemical fertilizers. The highest bulb and flower yield both per plant and per hectare were recorded in poultry manures followed by cowdung. The bulb and flower yields were higher in poultry manures might be due to increased side shoots number, bulb size and flowers plant-1. In contrast, the lowest bulb and flower yields were recorded in chemical fertilizers due to production of fewer side bulb and flowers plant-1.DOI: http://dx.doi.org/10.3329/jesnr.v4i2.10135J.
