Application of organic mulching is soil management practice that seeks to improve soil moisture conservation, increase soil fertility and improve crop production. The study was carried out to quantify the effect of different organic mulches on some soil properties at three crop stages and maize production under coastal savanna condition. Four treatments of mulch; maize stover (MS), dry grass straw (GS), palm frond (PF) mulches at 3 Mg ha-1 each and no-mulch (NM) (control) with three replications were laid out in a complete randomized block design. After two consecutive cropping seasons, different organic mulches had no significant effect on the examined soil properties at the seed emergence stage. However, at both tasseling and harvest stages, the differences of bulk density, total porosity, organic carbon content and macro-nutrients (NPK) among the treatments were significant and were in the order of GS > MS > PF > NM. The germination rate was in the order of NM (91.0%) > MS (89.9%) > GS (87.9%) > PF (86.8%). The effect of mulches on both the plant height and the LAI was in the order of GS > MS > PF > NM. The increase in grain yield over the control were GS= 23 %, MS= 16 % and PF =15 % while that of the WUE relative to the control were 155 %, 122 % and 58 % for GS, MS and PF respectively. Dry grass mulch could be used to improve soil properties and achieve higher maize production in the study area.

Present field experiment was conducted at farmer’s field in Ringondiya village, Madhya Pradesh during rabi season 2018-19 to study the effect of integrated nutrient management practices on performance of chickpea, basic soil properties and nutrient availability. The performance of chickpea (cv. JG-322) was evaluated under seven treatments viz., T1-Control, T2-100% N:P:K (20:50:20), T3-50% N:P:K + FYM @5 t ha-1, T4-50% N:P:K + vermicomposting @2 t ha-1, T5-50% N:P:K + PSB @4 kg ha-1, T6-50% N:P:K + FYM @5 t ha-1 + PSB @4 kg ha-1 and T7-50% N:P:K + vermicomposting @2 t ha-1 +PSB @4 kg ha-1 replicated thrice in a randomized block design. The grain yield, straw yield and harvest index of chickpea were determined at harvest. Similarly, the soil pH, electrical conductivity, soil organic carbon and soil available nutrients (N, P and K) were also determined in post harvest soil samples. The results revealed that the integrated nutrient management practice significantly improved the performance of chickpea. The soil organic carbon and available nutrients were also found increased under INM practices.

A two year field experiments were conducted at the College of Agriculture Teaching and Research Farm,   Jalingo, Taraba State, Nigeria, to evaluate the integrated use of 25% rates of  selected herbicides mixtures (atrazine-pendimethalin (AP1) or primextra (PX1) and cover crops (a vegetable cowpea, "Akidi" (A), Melon (M) and Sweet potato (S) planted sole or mixed at 20,000 stands/ha (1) or 40,000 stands/ha (3) under manual (MT) and tractor tillage (TT) methods used primarily for weed control on soil properties and maize production. The experimental design was a split plot arrangement in a randomized complete block design replicated three times. Tractor Tillage (TT) and Manual Tillage (MT) were the main treatments. The sub treatments included ten integrated weed management (IWM), AP1AI, AP1AS1, AP1S3, AP1MS3, AP1AMS3, PX1A1, PX1AS1, PX1S3, PX1MS3, PX1AMS3 in addition to Weeded 3+6 Weeks After Planting (WAP) (C1) and unweeded(C2) as controls. Descriptive statistics and Analysis of Variance were used to analyze data and the treatment means were compared using standard error at 5%. The level of Na, organic carbon, TN, %clay and %fine sand were higher in MT than TT during the experimental period while Mg, pH, %silt and clay were higher in TT than in MT. Herbicide groups did not significantly influenced soil properties in this study. The Ca2+, K+ and A-VP in all IWM treated plots were higher than the value in C2 . Treatments having Akidi (A1, AS1, AMS3) recorded higher OC than those without (S3, MS3). Therefore, MT improves soil condition and should be used in small scale farming and where TT is used, special consideration of soil type and frequency of use should be moderated. Use of IWM ameliorates fertility losses observed, with preference for mixture with at least a leguminous component.

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.

Various ways have been made to increase the productivity of rice plants as a source of staple food of Indonesian society. One ofthem is the addition of nutrients in the soil (fertilization). Currently, the innovation use of seaweed as fertilizer is widely used in several countries in the world, because seaweed contains phosphorus, potassium, and some other micro elements. This study aimed to analyze the use of various types of waste seaweed to improve the productivity of paddy rice on the ground Vertisol. The study lasted from December 2014 through Sept. 2015, at Greenhouse, Teaching Farm, Faculty of Agriculture, University of Hasanuddin Makassar. The research method is a randomized block design consisting of eight treatments and six replications (48 pot experiment). Each treatment is C0 (control), C1 (fertilizer N 300 kg / ha, P 100 kg / ha and K 100 kg / ha), G1 (Gracilaria 10 g / pot), G2 (Gracilaria 100 g / pot), S1 (Sargassum 10 g / pot), S2 (Sargassum 100 g / pot), K1 (Kappaphycus 10 g / pot), and K2 (Kappaphycus 100 g / pot). The addition of Sargassum seaweed fertilizer waste 100 g / pot and Kappaphycus dose of 100 g / pot can increase K-dd, Na- dd, base saturation, increase the value of N, P, K, and Ca-dd, but administration with concentrations of 100 g / no maximum pot for rice crop production by causing toxicity in plants. The addition of seaweed fertilizer waste treatment Gracilaria 100 g / pot is effective in improving Vertisol soil chemical properties and can provide maximum results for the productivity of rice plants

Application of manure for soil amendment plays important roles in reclaiming and improving soil properties of degraded soils. This study assessed the effects of composted and non-composted manures on a degraded soil under continuous maize production. The treatments applied consisted of composted manures in form of cassava based compost (CBM) and verticompost (VC) at the rate of 0, 30, 60 and 120 tons/ha, non-composted manure (NC) applied as poultry manure (PM), and an un-amended control plot. These treatments were laid out in a randomized complete block design replicated three times. Soil physical and chemical properties were determined for two consecutive seasons, with maize (SUWAN 1-SYR) planted as test crop. The CBM, VC and PM treatments increased the soil organic carbon content by 18.2, 24.1, and 22.3 % respectively. Corresponding increases observed in cation exchange capacity (CEC) were 13.6, 15.7, and 15.2 %. The comparison of the soil chemical properties measured indicated positive effects from the amendments on the soil properties in the order: CBM < PM < VC.  The maize grain yield of cassava based fertilized plot consistently and significantly was higher than the other treatments in both cropping seasons. However, both the composted and non-composted manures favored improved maize growth and resulted in higher grain yields (4.62 – 6.03 t ha-1) than the un-amended control treatment (3.69 t ha-1). The study therefore showed that the incorporation of manures, whether composted or non-composted, is beneficial to soils, improving one or more essential soil attributes thus reducing soil degradation.

Background: Utilization of palm mill liquid effluent and bat guano as organic fertilizer was initiated in year 2019 and 2020. The palm oil mill effluent and bat guano were used to produce compost and was tested on maize and soil properties in Asaba, Delta State. Methods: The compost was applied at 0, 2.5, 5.0, 7.5 and 10 ton/ha and replicated four times in randomized complete block design for two years. Plant height, leaf area, stem girth were assessed at maturity whereas yield parameters and soil chemical properties measured at harvest. Data collected were analysed with analysis of variance and means separated with Duncan’s multiple range test at 5% level of probability. Result: Compost significantly increased maize yields and soil properties. The 10 t/ha gave the highest dry matter yield (22.1±2.71 and 36.2±7.47 t/ha), weight of 1000 grains (324±41.0 and 364±63.3) and grain yield (5.2±1.04 and 6.4±1.61 t/ha) in both years, respectively. It also, had the highest soil pH value, organic carbon, total nitrogen and available phosphorus. The palm mill liquid effluent and bat guano mixtures have the potentials to be used as organic fertilizer for maize production.

Soilless culture is a technique of crop production using no soil. The main reason towards need for soil to soilless culture for horticultural crops is the problem related to proliferation of soil borne pathogen in the soil cultivation. Recent research studies reported that commercial production of greenhouse vegetables with soilless media has paved the way for reduction in economic losses caused by soil-borne pathogens. In this context, the present study was initiated to identify suitable substrate mixes for soilless culture. The experiment was laid out in a randomized block design. There were fifteen different media levels including control, with three replications. Crop Tomato TNAU hybrid CO3 were assessed for the mean performance in respect of growth characters namely shoot length, root length, germination percent and vigour index. The treatment Vermicompost: Coir pith (3:1) was found to have the highest value for growth characters for the crop. With regard to the physical and chemical properties, all combination media showed optimal range for crop growth. Further a cost analysis was made to find the suitable media based on cost aspects comparing reduction in vigour index and cost of media with that of best media. Treatment T7 (Vermicompost: coir pith (2:1)) and T6 (Vermicompost: Coir pith (1:3) were found to be the best media considering above factors.

The objective of this work was to characterize the chemical properties of white oat (Avena sativa) caryopsis and to determine the adaptability and stability of cultivars recommended for cultivation in the state of Rio Grande do Sul, Brazil. The trials were carried out in the 2007, 2008 and 2009 crop seasons, in three municipalities: Augusto Pestana, Capão do Leão, and Passo Fundo. Fifteen cultivars were evaluated in a randomized block design, with four replicates. The contents of protein, lipid, and nitrogen-free extract were evaluated in the caryopsis. Cultivar performances for the measured characters varied according to location and year of cultivation. The cultivar URS Guapa showed high content of nitrogen-free extract and low contents of protein and lipid in the caryopsis. 'FAPA Louise' showed high content of lipid, whereas 'Albasul', 'UPF 15', and 'UPF 18' showed high content of protein and low content of nitrogen-free extract. There is no evidence of an ideal biotype for the evaluated characters, which could simultaneously show high average performance, adaptability to favorable and unfavorable environments, and stability.

To achieve the objectives of the study, a field experiment was conducted in the area of Judaim 5 km east of the city of Zawiya - Libya at the farm of citizen Juma Al-Marhoon 2018. The experiment was designed with the design of randomized complete block design (RCBD Factorial) of three replicates, two varieties of bean crop (Viciafaba.L) (Cyprus and Aquadulcy), and two types of irrigation water (magnetic water Mw and non-magnetic water (N Mw). Soil samples from were collected at different depths over three time periods (after one and a half months and three months after harvesting). Some chemical properties of the samples were analyzed and measured. The results of statistical analysis of experiment data showed that the irrigation of the two varieties of bean crops (Cyprus and Aquadulcy) with magnetized water Mw compared to the non-magnetized water N Mw increased significantly in the number of plant branches and plant height. The increase was high significant in germination rate. The increase in productivity was significant in the weight of dry pods, the weight of dry seeds and the total weight of the plant and very high significant in the weight of 100 seeds (g). The other characteristics of the plant, such as vitality, weight, number of root nodes and harvesting index, were not affected by magnetic water. The results of the statistical analysis of soil collected in the first and third stage showed no significant differences between soil irrigated with magnetic water and irrigated soil with untreated water in most of the chemical properties of the soil, except for the dissolved potassium K and pH, the differences were highly significant in the soils collected in the third stage. The results of the statistical analysis of soil data collected in the second stage showed significant and high significant differences between soil irrigated with magnetic water and soil irrigated with untreated water in most of the chemical properties of the soil.
