Farmers use Inorganic Fertilizers (IF) to improve kenaf yield in Nigeria. However, the detrimental effects of mineral fertilizers and its high cost calls for the use of organic fertilizers that are locally available and environment friendly. Combination of Organic Fertiliser (OF) with IF may reduce the bulkiness of OF while harnessing the benefit of both for higher yields. Field trials were conducted at Ibadan and Ilora in 2013 and 2014 to investigate the effects of combined fertilizers on the growth and yield of kenaf. Organic and IF (NPK 20:10:10) fertilizers as: (i) 160 kg ha-1 (sole organic), (ii) 100 kg ha-1 (sole IFl), (iii) Organic and IF at 50:50 ratio and (iv) control (no fertilizer). The experiment was laid out in Randomized Complete block design (RCBD) and replicated three times. Results showed that plant height (220.17 cm, 216.80 cm) and stem diameter (2.27 cm, 1.16 cm). Bast fiber (2.27 t/ha, 2.27 t/ha) and seed yield (1.69 t/ha, 1.78 t/ha) in Ibadan and Ilora respectively were significantly higher in plots with combined fertilizer. Combined fertilizers had the highest fiber and seed yield above sole application and control (no fertilizer application). Hence it is recommended for kenaf cultivation in Southwest Nigeria.

У статті обґрунтовано необхідність вивчення проса прутоподібного (світчграсу) як енергетичної культури, сировину якої доцільно використовувати для виробництва різних біопалив: рідких, твердих та газоподібних. Матеріалом для дослідження були рослини та насіннєвий матеріал сорту проса прутоподібного іноземної селекції Кейв-ін-рок. Здійснено спробу визначити оптимальні умови (за гідротермічним коефіцієнтом і з урахуванням родючості ґрунтів) для отримання високого врожаю насіння в умовах України та шляхи підвищення його посівних кондицій. За результатами трьохрічних досліджень встановлено вплив погодних умов веґетаційного періоду на продуктивність насіння проса прутоподібного. Експериментальним шляхом визначено лімітуючі фактори та шляхи їх нівелювання для забезпечення гарантованого отримання якісного насіннєвого матеріалу в умовах Лісостепу. Аналіз результатів досліджень дав змогу встановити вплив біометричних (кількісних) показників генеративної частини рослин (довжини та кількості волотей на рослинах, маси 1000 насінин) на насіннєву продуктивність, що обумовлюють і загальний урожай насіння. Визначено вплив крупності насіннєвого матеріалу та терміну зберігання його на лабораторну схожість насіння у взаємозв’язку з особливостями його формування на материнських рослинах за різних умов вирощування. Necessity of studying switchgrass as an energy crop, raw material of which may be used for producing different types of biofuel such as liquid one, solid and gaseous ones has been substantiated in the article. The foreign experience of obtaining switchgrass seed of high quality has been investigated on the basis of scientific publications. We have established the limiting factors affecting seed yield, sowing characteristics, germination conditions, growth and development of plants in the early periods of vegetation. The attempt of determining optimal conditions (by hydrothermal coefficient and soil fertility) for providing high seed yield in Ukraine as well as ways of increasing seed characteristics has been made. Many years’ experiments were conducted in the central part of Forest-Steppe of Ukraine on two types of soils: high-productive soil with humus content of more than 4 % and nutrient lean soil with humus content of less than 2 %. Research material was plants and seed of Cave-in-Rock switchgrass variety of foreign selection. The methods of testing, field and laboratory experiments, scientific recommendations were applied in the experiment. The experimental results were processed by the dispersion analysis and correlative-regression analysis with application of the computer program Statistics. After three years of investigation, influence of the vegetation period weather conditions on switchgrass seed productivity has been established. The limiting factors and the ways of decreasing their effect in order to provide guaranteed getting of high quality seed material in the conditions of Forest-Steppe of Ukraine have been defined by the experiments. At the same time the effect of soil conditions on the crop seed productivity has been proved. The analysis of the research findings enabled to show influence of biometric (quantitative) characteristics of the generative plant part (length and number of panicles per the plant, mass of 1000 seeds) on seed productivity that affect total seed yield. Besides, influence of seed material size and storage period on laboratory seed germination in the interconnection with seed formation peculiarities on maternal plants in different cultivation conditions has been determined. The yield of switchgrass seeds depends on weather factors and soil fertility. Also we defined influence of quantitative characteristics in the generative plant part – length and number of panicles per the plant, mass of 1000 seeds on seed yield. Laboratory germination of seeds depends on the storage size and the mass of 1000 seeds.

Background: Intensive rice cultivation for longer periods continuously resulted in poor soil fertility. Inorganic fertilizers along with integrated and judicious use of different organic sources like FYM, vermicompost, green manure etc. could be an effective choice for enhancing crop yield. A synergistic effect on crop yield is reported through common use of fertilizer and organics which also improve soil fertility. The residual effects of organic manures applied to the preceding crops can be available to succeeding crop. Therefore, this experiments was planned to throw light on the use integrated nutrients through organic and inorganic sources on rice and its residual effect on succeeding greengram. Methods: A field experiment was conducted to study the effect of integrated nutrient management on rice-greengram cropping sequence at Navsari Agricultural University, Gujarat during 2012-15. Five nutrient combinations were evaluated in randomized block design for rice and its residual effect on productivity on succeeding greengram was studied with three fertilizer levels in split plot design. Result: Application of general recommended dose of fertilizers (RDF) to rice has increased growth, yield, quality, economics and improved soil properties and the residual effect to succeeding greengram have also gave significantly higher greengram seed yield and other important parameters and this was succeeded by application of 75% RDF through chemical fertilizer + 25% RDF through vermicompost. Among different levels of fertilizers to greengram, application of 100% RDF gave highest greengram seed yield, economics and soil parameters over other two levels.

Due to the complexity of the relief of Mountain Shirvan, the dominant gray-brown soils, subject to varying degrees of erosion, have lost their fertility. To restore and maintain of these soil fertility, vermicompost and inorganic fertilizers were introduced under winter barley in various versions. It was revealed that the highest crop yield falls on the option of 6 tons of vermicompost per hectare. In this variant, the length of the ear of barley was 11.2 cm, the number of grains was 33, the weight of grains from 1 m2 was 183.6 g and the weight of 1000 grains was 44.7 g. 10–15% with the option of inorganic fertilizers. In this connection, the widespread use of vermicompost is considered expedient both from an economic and an ecological point of view.
