Though needed in very small quantities, micronutrients are as important as primary and/or secondary nutrients in yield-formation and in enhancing crop-quality. Twenty four field experiments (18 sulfur response; and six sulfur rate determination), therefore, were conducted to evaluate the micronutrients fertility of soils in three locations in central Ethiopia, during 2013-16. In doing so, 54 surface soil samples (24 before planting; and 30 after wheat harvest) were analysed using standard laboratory (Lab) methods. Some soil and crop yield variables were subjected to SAS statistical analysis. The results showed that iron, zinc, boron and molybdenum were low; whereas cupper and manganese were adequate in most studied soils. Among others, lack of nutrient recycling was the major cause for the observed micronutrients deficiency. Soil factors such as pH, organic carbon, CaCO3 and parent material also have contributed to the low fertility of micronutrients vis-à-vis their contents in soils. Therefore, strategies involving soil enhancement by seed treatment or the use of organic amendments of different sources can be adopted to sustain optimum crop-yields and quality. Hence, in addition to the previous recommendations on sulfur, the deficient micronutrients need to be included in the balanced fertiliser formulas, if soil-test, plant-tissue analysis and/or crop-responses data are available. It is well recognised that, micronutrients application to soils is not economical in large scale productions, possibly due to the different losses in relation to their small quantities to be applied. Furthermore, the deficiencies of elements like zinc and iron can be acute when alkaline soils like that of East-Shewa are brought under irrigation. Because of such problems, and adverse reactions, the use of special protective complexes (chelates), and direct application of the micronutrients to plant-foliage via foliar sprays or fertigation may be recommended. In some cases, food enhancement of the deficient micronutrients can also be adopted.

Trichoderma is an environment friendly soil borne fungus that speeds up decomposition of organic materials into compost. Currently, many farmers in Bangladesh are using Tricho-compost to increase soil fertility and to get higher crop yield. A study was conducted with the purpose of determining: (i) the farmer’s livelihood improvement as a result of tricho-compost application in soil, (ii) the personal and socio-economic characteristics of the farmers’, and (iii) the contribution of socio-economic characteristics of farmers’ to their livelihood status. For the qualitative experiment, the rural farmers involved in tricho-composting were the population under the study. A total of 20 locations were purposively selected from 120 locations and 10 respondents from each of the location were randomly selected to make a sample size of 200. Livelihood status of the farmers was the dependent variable while personal and socio-economic characteristics of the farmers were the independent variables which included age, education, family size, farm size, annual income, extension media contact, cosmopoliteness, agricultural knowledge, innovativeness, housing condition, sanitation, livestock possession, household asset, receipt of loan and environmental awareness. These characteristics were measured using standard statistical scoring techniques. The regression coefficient of eight variables namely education, annual income, extension media contact, cosmopoliteness, agricultural knowledge, livestock possession, household assets and environmental awareness were statistically significant indicating that these variables had a significant contribution to the livelihood status of Trichoderma practicing farmers. The other seven variables had no significant contribution to the livelihoods of farmersTricho-composting has a lot of contribution in changing the livelihoods of the farmers.

The research was conducted at the Teaching and Research Farm of the Faculty of Agriculture and Natural Resources Management, Enugu State University of Science and Technology within latitude, 06° 171 58° 6” N and longitude 07°, 321, 58° 8”E on a total land area of 225m2 (15 m x 15 m). The research was aimed at finding the effect of different rates of NPK 15:15:15 fertiliser on the physicochemical properties of the soil, growth and yield of cucumber (Cucumis sativus L.). was designed in  a  Randomized  complete  Block  Design (RCBD), with five replications and four treatments which are 0 kg/ha (T1) 50 kg/ha (T2), 100 kg/ha (T3) and 150 kg/ha (T4). The study showed that a significant (P = .05) effect in the yield was obtained at the rate of 150 kg/ha at 8 weeks after planting. The following yield and other agronomic parameters were obtained using 150 kg/ha. Fruit yield 18.75 t/ha and vine length 181.37 cm. Therefore cucumber farmers are advised to apply 150 kg/ha of NPK 15:15:15 fertiliser for their optimum yield.

To study the effect of sulphur and boron on post-harvest soil fertility status, a pot experiment was conducted at Department of Soil Science and Agricultural Chemistry, Institute of Agricultural sciences, Banaras Hindu University, Varanasi during the kharif season of 2017 taking sesame as a test crop in red soil of Mirzapur district of Uttar Pradesh. The available nitrogen, phosphorus, potassium, sulphur and boron contents were recorded significantly higher in soil after harvesting of the crop over control. The nitrogen, phosphorus, potash, sulphur and boron content recorded 131.58 kg ha-1, 9.25 kg ha-1, 228.48 kg ha-1, 32.79 kg ha-1 and 5.58 mg kg-1, respectively when soil treated with 50 kg S ha-1 and 2 kg B ha-1 after harvest of the crop. Correlation study of the data shows the a significant and positive interaction between soil properties. Available sulphur was positively correlated with available phosphorus (r = 0.875*) while as organic carbon was also significant and positively correlated with available nitrogen (r = 0.935*), phosphorus (r = 0.891*) and potash (r = 0.882*). Multiple regression equation revealed that more than 90% variation in available S was attributed by physicochemical properties of the soil.

The major method of propagation of varieties and hybrids of Paulownia elongata is vegetative (asexual)  method. Paulownia elongata can be propagated by macropropagation techniques (root cuttings, green cuttings and by micropropagation technique, tissue culture or in vitro. Today the tissue culture method is the most modern biotechnological method.  In Bosnia and Herzegovina and regions of former Yugoslawia, more and more Paulownia elongata seedlings are being produced and new plantations of Paulownia elongata areestablished. This paper deals with the methods of propagation and problems in raising Paulownia elongata planting materials. The work aims to produce seedlings of fast-growth Paulownia elongata, Shan Tong hybrid and the possibility of  propagation through different methods. Propagation by green cuttings, root cuttings and in vitro propagation was tested.  After 15 days, the percentage of rooting for the green cuttings was 100%, and there were no dead plants, the average number of roots was 13.86 pcs per plant and roots were of different lengths. The length of the cuttings had an impact on the growth of plants because the smallest cuttings was of 1.5 cm (4 pcs from 30 plants or 1.33%), whereas cuttings of 5 cm (26 out of 30 plants or 86.6%), showed the best rooting. For in vitro propagation, meristems of mother plants were used for establishing of tissue culture. The plants showed a survival rate of  80-90% . Production of Paulownia elongata seedlings by different methods of vegetative propagation provides a variety of options to producers, depending on what kind of equipment they have. In vitro production is the most expensive but also the fastest method because a large number of seedlings can be produced in a short time. It is recommended that in vitro propagation should be used to build mother plant stock and that in the coming 2-3 years the green cuttings from super-elite planting material are going to be used.
