Effect of biofertilizers on yield and morphological parameters of onion cultivars

Abstract The present study evaluated the effect of different organic fertilizers on the morphological parameters and yield in two different onion cultivars. Proper use of organic fertilizers in appropriate amounts could be helpful to growers from the economic point of view. Field experiments were conducted to study the effect of three different organic biofertilizers on yield and morphological parameters of two onion cultivars ‘Stuttgarter Riesen’ and ‘Rote Laaer’ during 2016 and 2017. The investigated treatments included: B-Stimul® – a mixture of bacterial and algal extracts, EkoBooster 2® – organic matter and NPK, and VermiFit A® – an extract of compost produced by Californian earthworms, peat, nutrients, plant hormones, enzymes, amino acids, and sugars. The following parameters of onion plants were evaluated: number of leaves, bulb diameter, bulb weight, marketable and total yields. The study showed that all the results were affected by the growing season (higher values were recorded in 2016). In ‘Stuttgarter Riesen’, EkoBooster 2® application resulted in the highest bulb weight in 2016 (67.16 g) and in 2017 (55.17 g) and in the highest number of leaves in 2016 (6.66) and in 2017 (6.30), which led to the highest marketable bulb yield in 2016 (3.47 kg m−2) and in 2017 (2.53 kg m−2). In ‘Rote Laaer’ in 2016, EkoBooster 2® application resulted in the highest number of leaves (7.06), bulb diameter (54.32 mm) and bulb weight (79.30 g). In 2017, the largest bulb diameter (54.13 mm) and the highest bulb weight (71.79 g) and marketable bulb yield (2.39 kg m−2) were determined after VermiFit A® application. EkoBooster 2® showed the best effect on parameters such as the number of leaves, bulb weight, and marketable bulb yield of the cultivar ‘Stuttgarter Riesen’ and positively affected the parameters of ‘Rote Laaer’ during 2016, while in 2017 VermiFit A® showed better results as compared to the other treatments.

Determination of the effects of different organic fertilizers and doses on soil properties

Organik gübreleme topraklarda verimlilik parametrelerinin artırılmasında kullanılan en etkili yöntemlerden birisidir. Organik gübreler toprak özelliklerinde iyileştirmeler sağlarken bir yandan da üzerinde yetiştirilen bitkilere verim ve kalite açısından katkı sağlamaktadırlar. Bu çalışmada; organik gübre olarak Tavuk Gübresi (TG)(0 kg da, 100 kg da-1, 200 kg da-1, 300 kg da-1), Çiftlik Gübresi (ÇG) (0 kg da-1, 100 kg da-1, 200 kg da-1, 300 kg da-1), Vermikompost (V) (0 kg da-1, 100 kg da-1, 200 kg da-1, 300 kg da-1) ve Leonarditin (L) (0 kg da-1, 50 kg da-1, 100 kg da-1, 200 kg da-1) artan dozlarının dört tekerrürlü olarak saksı koşullarında marul yetiştirilen toprakların bazı fiziksel ve kimyasal özellikleri üzerine olan etkileri belirlenmeye çalışılmıştır. Farklı organik gübrelerin topraklarda pH, EC, organik madde, N, P, K, Ca, Zn ve Cu içeriklerinde özellikle TG ve ÇG uygulamaları etkili olmuştur. Uygulama dozları bakımından yapılan değerlendirmede ise EC, organik madde, N, P, K, Ca, Fe ve Mn içeriklerinde doz etkileri önemli olarak belirlenmiş ve genel olarak 200 kg da-1 ve 300 kg da-1 dozları öne çıkmıştır. Farklı organik gübrelerin toprak özellikleri üzerine etkilerinin belirlenmesi açısından birlikte uygulamaların yapılmasının en iyi materyal, doz ve kombinasyonların belirlenmesinde avantaj sağlayabileceği görülmektedir.

Performance of different organic fertilizers in improving growth and yield of boro rice

A field experiment was conducted at two locations i.e. at Soil Science Field of Bangladesh Agricultural University and at Farmer’s field of Fakirakanda village of Mymensingh Sadar to evaluate the effects of different organic fertilizers on the growth and yield of rice (BRRI dhan28). The experiments at each location containing seven treatments were laid out in a randomized complete block design with three replications. The treatments were T0: Control, T1: 75% RFD; T2: 100% RFD, T3: 75% RFD + Kazi Jaibo Shar (5 tha-1), T4: 75% RFD + Kazi Jaibo Shar (3 t ha-1), T5: 75% RFD + Poultry manure (3 t ha-1) and T6: 75% RFD + Cow dung (5 t ha-1). Application of poultry manure as well as Kazi Jaibo Shar showed positive effects on yield attributes, grain and straw yields of rice, nutrient (N, P, K and S) contents and uptake by grain, straw and in total. The performance of 75% RFD with poultry manure @ 3 t ha-1 was the best in producing yield components, grain and straw yields of rice. At both locations, the performance of same dose (3 t ha-1) of poultry manure and Kazi Jaibo Shar was almost similar in producing growth and yield contributing characters, grain and straw yields, - nutrient content and uptake by rice while each of these manures compensated up to 25% of recommended chemical fertilizers. Therefore, considering the soil health, poultry manure or Kazi Jaibo Shar @ 3 t ha-1 is recommended for growth and yield enhancement in rice.

The Effect of Different Organic Fertilizers and Different Localities on Crop Yield in Conditions of Organic Farming

Nitrogen fertilization of plants during the vegetation is very problematic in terms of organic farming. The balanced crop rotation and versatile nutrition are essential for maintaining good yields and high‑quality products. The application of organic fertilizers and incorporation of green manure crops are one of the best options for achieving optimal results in organic farming. The goal of this long‑term research was to examine the effect of several different organic fertilizers and divergent experimental stations on crop yield in conditions of organic farming. a total of 6 variants of fertilization were evaluated in this experiment: 1. unfertilized, 2. green manure (GM), 3. GM + renewable external sources, 4. GM + renewable external sources + biostimulants, 5. GM + farm fertilizers, 6. GM + farm fertilizers + biostimulants. The winter wheat was sown at the start of the experiment in autumn of 2014. Therefore, green manure was not cultivated in the first experimental year. The results from the first year of this experiment showed, that the variant with renewable external resource (digestate) provided the highest yield. The average yield of wheat grain on this variant was about 7.12 t/ha, which is increased by 0.74 t/ha in comparison with unfertilized control variant. The potatoes were used as a model crop in second year of the experiment. The highest yield of potatoes coming from the second experimental year was observed on the combination of green manure + renewable external sources (compost and digestate) + biostimulants. The average yield of potatoes on this variant was about 34.08 t/ha. The yield of potatoes observed on the unfertilized variant was lower by 9.35 t/ha. The content of nitrogen in organic fertilizers (compost and digestate) was higher in comparison with other organic fertilizers used in the experiment, which probably caused these results. The winter wheat spelt was used as a model crop in the third year of the experiment. The application of organic fertilizers was completely omitted in this year. The highest average yield of spelt (5.5 t/ha) was observed on the variant called green manure + farm fertilizers. The average yield achieved on the unfertilized variant was lower by 0.7 t/ha. The result from this three experimental years point out the similarity between farming with and without animal husbandry in organic farming. The statistical differences between experimental stations were observed in experimental years.

Response of wheat crop during transition to organic system under Mediterranean conditions

Organic agriculture is an ecological production management system aimed at sustainableproduction of safe food, environmental protection and maintenance of soil health. The objectiveof this study was to evaluate, in a period of organic transition, the effects of different organicfertilizers on wheat yield, grain quality and soil characteristics. The research was performedin an experimental farm of Southern Italy (Foggia), over a three year period. An organiccommercial fertilizer and compost, obtained from municipal wastes, with and without acommercial bioactivator, were compared in a randomized block design. Grain yield and qualityand soil total organic carbon content (TOC) were measured. The Henin-Dupuis model was alsotested to simulate soil organic C dynamics after organic fertilizer application. Among the years,significant differences were observed in grain yield and quality, indicating that wheat cropresponse was influenced by the weather conditions. The grain and straw yield was notsignificantly affected by the organic fertilizer used, though the compost resulted in significantlylower grain quality compared with the organic commercial fertilizer. In any case, at the end ofthe experimentation, the compost resulted in significantly higher TOC (+4%) compared to theorganic commercial fertilizer. The results showed that the compost may be used as analternative to sustain wheat productivity, feasible also from an economic point of view and toconserve soil fertility. Finally, under the local Mediterranean conditions, the soil organic Cdynamics could be defined by the Henin-Dupuis model, also considering the C supply of annualroot residues.

Effects of organic fertilizers on the vegetative, nutritional, and productive parameters of blueberries ‘Corona’, ‘Legacy’, and ‘Liberty’

Organic farming does not allow using certain inputs, such as N, which differ in nutrient release rates and dynamics. To evaluate the effect of different organic fertilizers on the vegetative, nutritional, and productive parameters of blueberries (Vaccinium corymbosum L.), a pot experiment was conducted in three consecutive seasons in a sandy soil of south-central Chile using 'Corona', 'Legacy' and 'Liberty'. The following fertilizers were evaluated: compost (CM), Purely Grow (PG), Purely Lysine (PL), Fertil (F), blood meal (BM), lupine meal (LM), along with a control treatment without fertilization (C) and two conventional treatments with urea (CF) and sodium nitrate (S). Results indicate that vegetative growth and leaf N concentration prior to senescence were different among cultivars in the three evaluated seasons. The highest leaf N concentration was recorded in 'Corona' followed by 'Legacy' and 'Liberty' while levels tended to increase in the seasons. Quick-release N sources had greater effects on these parameters but with differences among cultivars. Fruit yield and weight were higher in 'Corona' followed by 'Legacy' and 'Liberty'. Fruit yield was generally higher when using LM and F and showed no effect on fruit weight. Leaf chlorophyll content was higher in 'Corona' followed by 'Legacy' and 'Liberty', which increased when using CF, LM, BM, and PG. Finally, the organic fertilizer and blueberry cultivar that obtained the highest values for most of the evaluated parameters were LM and Corona, respectively.

Effect of organic fertilizers on physical and chemical quality of sugar loaf pineapple (Ananas comosus L) grown in two ecological sites in Ghana.

Pineapple has a large demand for plant nutrients and for this reason; fertilization is almost mandatory where the fruit is destined for sale. As consumer demand for organic food grows, organic production and certification is seen as a valuable alternative for smallholder farmers in developing countries. This study sought to investigate the effects of different organic fertilizers on the physical and chemical quality of pineapple (Ananas comosus L.) cultivated in two different ecological zones in Ghana. Organic fertilizers treatments were POME (Palm oil meal effluent), Phos-K (PH), Yara (Y) and combination of Phos-K and POME (PH+P) and Yara + POME (Y+P) in the ratio of 1:1. Soil without fertilizer was control. A farmer field demonstration and an on-station experimental trial were conducted parallel at Nsakyi and at the Biotechnology and Nuclear Agriculture Research Institute (BNARI) research farm, respectively. The experiment was laid out in the Randomised Completely Block Randomized Design (RCBD) with five fertilizer treatments and four replications. Sugar loaf pineapples were harvested at 17 months upon maturity, washed, peeled, and juice extracted for analyzing vitamin C, Total Soluble Solids, pH, Titratable acidity, juice yield and colour. Fruits were weighed with Sartorius scale and percentage weight loss estimated over 15 days. The weight loss of pineapples treated with POME (25.56 ± 0.62 %) from BNARI farm was significantly (p<0.05) higher than all the other pineapple treaments. pH of all pineapple samples significantly (P<0.05) differed for all the different fertilizer treatments for both farms. Phos-K significantly (p<0.05) enhanced the vitamin C content of pineapples from both ecological sites Lightness (L*) and yellowness (b*) for juice of pineapple treated with Phos-K from BNARI farm was significantly (p<0.05) higher, than samples from Nsakyi farms indicating desirable visual appeal for sugar loaf pineapples. Organic fertilizers significantly (p<0.05) influenced the pH, vitamin C and juice yield of pineapples grown in the two different ecological zones. Irrespective of the ecological differences in Nsakyi and BNARI farm sites, the application of Phos-K to pineapple significantly (p<0.05) increased the juice yield which is a desirable quality of pineapple. Thus the application of Phos-K organic fertilizer, better improved the physical and chemical quality attributes of pineapple. However, there is the need to conduct further work on application rate and utilization efficiency of organic fertilizers that will produce maximum pineapple quality and yield.

English

The purpose of this study was to evaluate the effects of different organic fertilizers on yield and fruit qualities of indeterminate tomato. Influences of different organic and inorganic fertilizers on yields and fruit qualitiy of tomato were compared during 2006 and 2007 growing periods under field conditions. In 2006 growing period, organic fertilizes used were Ormin K (250 kg/ha before planting; 30 kg/ha after first flowering; 80 kg/ha after first harvest), Coplex (50 kg/ha every week from planting to last harvest), Nof (40 kg/ha every week, from planting to last harvest), composted poultry manure (CPM) (1 t/ha before planting; 0.5 ton/ha after first flowering and 0.5 ton/ha after first harvest (liquid form)) and composted cattle manure (CCM) (60 t/ha before planting; 5 ton/ha after first flowering and 5 ton/ha after first harvest (liquid form)). Based on the first year results, organic fertilizers used during 2007 growing periods were F1 (20 ton/ha CCM before planting; 1 t/ha CPM before planting; 40 kg/ha Coplex and 20 kg/ha Nof every week) and F2 (20 t/ha CCM before planting; 500 kg/ha Ormin K before planting; 30 kg/ha Coplex and 30 kg/ha Nof every week). Inorganic fertilizers used as a control were N: 450, P2O5: 350, K2O: 600, CaO:50, S: 200, and Mg:50 kg/ha. Tomato cultivars used in this study were Alida FA± in 2006 growing period and Alida FA±, YankA± FA± and Maya FA± in 2007 growing period. In 2006, the highest yields obtained from CPM, CCM, and control treatments were 128.12, 122.92 and 115.24 t/ha respectively. In 2007, marketable yield obtained from F1 fertilizer treatment was similar to the control application. Unmarketable yield was not effected from the different fertilizer treatments. There was no significant difference among the treatments. However fruit cracking rates were higher in organic fertilizer treatments than the inorganic fertilizer treatment. Finally, application of 20 to 40 t/ha composted cattle manure befor planting and addition of commercial organic fertilizers such as coplex, nof and ormin K can be used as an alternative to the chemical fertilizers in indeterminate tomato cultivation. Key words: Tomato, organic fertilizer, cattle manure, poltry manure, yield.

Effect of different organic treatments on ex situ conservation of Polygonatum cirrhifolium Royle

Polygonatum cirrhifolium Royle (Meda), a herb belonging to the Liliaceae family, is known for its medicinal, cultural and ethno-botanical uses. However, due to its great market potential, it is harvested and grown in an uncontrolled way; overexploitation has caused the decline of the herb from its natural habitat. Since finding new organic treatments can help conserve the plant, a 2-year field experiment was undertaken to study the effect of different organic fertilizers and the nature of nursery beds on the survival, morphological growth and yield of this plant. The observations were recorded in 15-day intervals. The results show that yield was lower in control beds when compared with forest litter, farmyard manure and vermicompost in all type of beds prepared in rows, furrows and plain. The yield was highest at beds located at plantation with furrows which were supplemented with forest litter. Thus, it can be concluded that the cultivation of P. cirrhifolium is optimal in beds with rows and furrows (plantation in furrows) and supplemented with forest litter. In addition, composted organic material also improves both soil quality and fertility and regulates water. To the best of our knowledge, this is the first study on ex situ conservation of P. cirrhifolium from Kumaun Himalaya.

Efecto de la aplicación de abonos orgánicos en la supresión de <i>Pythium myriotylum</i> en plantas de tiquisque (<i>Xanthosoma sagittifolium</i>)

Los abonos orgánicos ejercen efecto supresivo sobre patógenos de planta; su capacidad supresora varía de acuerdo al tipo de abono y al sistema planta-patógeno. Se evaluó el efecto supresor de diferentes abonos orgánicos en el sistema tiquisque-Pythium myriotylum. Se determinó la madurez, estabilidad, y actividad microbiana de los diferentes abonos, así como el efecto del tipo de compostaje (compost vs vermicompost), el material de origen (estiércol vs broza de café) y el grado de madurez, sobre la supresión del patógeno. El efecto supresivo sobre el desarrollo de la enfermedad en plantas de tiquisque se estableció por medio de una escala visual de síntomas a los 3, 6 y 9 días del transplante. Los abonos presentaron relaciones C/N entre 6 y 15 y ninguno afectó la germinación o la longitud de las raíces de plántulas de pepino. Los abonos maduros clasificaron como estables y los inmaduros, con excepción del compost de broza, como inestables. La menor incidencia de pudrición de raíces por P. myriotylum se obtuvo con el uso de vermicompost a base de estiércol maduro, mientras que la menor severidad de la enfermedad ocurrió cuando el suelo se enmendó con el compost y el vermicompost maduro a base de estiércol. En términos generales los abonos obtenidos a partir de estiércol fueron más supresivos, y presentaron una mayor actividad microbiana, que los producidos a base de broza de café. Se concluye que el tipo de compostaje, el origen y el grado de madurez tienen influencia sobre la capacidad supresora.

Direct and Residual Effect of Different Organic Fertilizers on Potato and Cereals

AbstractField experiment with 8 different organic fertilizers (cattle dung with and without litter, pig slurry, peat compost formed from hen and pig slurry, sawdust‐duck manure, noncomposted peat and straw litter with pig slurry) was carried out on loamy brown podzoluvisol since 1985.The organic fertilizers were applied in the spring of 1985 on two backgrounds: with and without mineral fertilizers. The material is based on the data of four years (1985–1988). The arrangement of crops was the following: potato, spring wheat, barley and early barley.On both backgrounds cattle dung with litter turned out to be the best organic fertilizer, while noncomposted peat manure had a low direct and residual effect. However, before the application it must be composted with pig or hen slurry. The effect of peat composts was dependent on the background of mineral fertilizers. Pig slurry had a low residual effect and acted only as a liquid nitrogen fertilizer. The joint application of straw and pig slurry can be a suitable opportunity for diminishing their undesirable effects.
