Improving the fertility status of nutrient-depleted soils is critical to achieving food security. The negative effects chemical fertilizers on necessitate global quest for eco-friendly, effective, and sustainable alternatives. This work assessed effect black soldier fly (BSF) residue application soil properties watermelon growth. study was set up in a completely randomized design with six replications. treatments were BSF1 (BSF applied at 10 t ha−1), BSF2 (20 BSF3 (30 control. plant data...

Low agricultural productivity is a threat to achieving global food security. Improving of degraded soils key sustainable production. This study investigated the effects four organic amendments (OAs) (Mushroom Compost, MC; PAS-100 compost, PAS; Anaerobic Digestate Solid Waste, AD_SW; and Poultry Manure, PM), applied at 10 t ha-1 30 on physical, chemical biological Soil Quality Indicators (SQIs) sandy loam soil. The OAs had about 76 49.1% (p < 0.05) increase in Olsen P soil matter compared...

Acid soils are highly weathered and usually excessive in soluble aluminum manganese deficient phosphorous, calcium, magnesium molybdenum, which may cause their reduced uptake lead to nutrient imbalances plants.To address this problem, a field study was carried out 2012 evaluate the residual effects of combined rates poultry manure (PM) NPK 15-15-15 fertilizers on responses maize (Zea mays L) soil limed different pH levels.The treatments were four levels pH: 5.5 (control), 6.0, 6.5and 7.0 six...

There are insufficient data supporting the enormous potential of biochar in highly weathered tropical soils. This glasshouse study assessed rice-husk (RHB) effects on soil organic carbon, aggregate stability and nitrogen fertility sandy-loam Ultisols which were evaluated using spinach (&lt;em&gt;Celosia argentea&lt;/em&gt;) growth. Five RHB rates 0, 5, 10, 20, 40 g per two-kg-soil (0, 7.5, 15, 30 60 t ha&lt;sup&gt;−1&lt;/sup&gt;, respectively) studied under 4, 8, 12 weeks incubation (WOI)....

Abstract Purpose Rice-mill wastes are generated in large amounts Ishiagu, Ebonyi State, Nigeria. These can potentially be utilized for rice production and improving soil attributes. This study evaluated the effects of rice-mill on chemical properties yield sawah management. Methods A field an inland valley southeastern Nigeria was used 2014 2015 cropping seasons study. Sawah refers to Indo-Malaysian term paddy. It involves manipulation some physical form ecological engineering works, by...

One of the main UN Millennium Development Goals is eradication poverty and hunger through food security.Unfortunately, this goal difficult to achieve in Nigeria due soil degradation, low fertility, other agricultural challenges.The current research on security focused improving fertility using low-cost organic amendments.Thus, 2019, study investigated residual effects repeated animal manure application cucumber (Cucumis sativus L.) yield, nutrient uptake, status a coarse-textured Ultisol...

Aims: The aim was to evaluate the performance of cultivating oyster mushroom (Pleurotus ostreatus) using sawdust and different organic manures. &#x0D; Study Design: experimental design used complete randomized (CRD) Data obtained subjected Analysis Variance (ANOVA) followed by Turkey’s Least Significant Difference(LSD) test compare treatment means; differences considered significant at 95% (P≤0.05) (SPSS Version 21 software).&#x0D; Place Duration Study: National Biotechnology Development...

The study investigated the effects of animal manures (cow manure, CoM; chicken droppings, CkD; and pig PiM) applied at 15 t ha-1 equivalent rate on soil growth performance okra grown in a degraded ultisol. treatments (CoM; PiM Control unamended) were laid out completely randomized design replicated three times. Animal manure application had significant properties. Soilorganic matter increased by over 9% amended treatment relative to control treatment. Except for N, increases P (circa...

Low soil fertility is one major drawback to Egusi melon (Colocynthis citrullus L.) production, a popular and premium crop in southeastern Nigeria.To overcome this challenge, study evaluated the effects of different animal manure types on egusi cultivation selected properties.The experiment was arranged completely randomized design with four treatments three replications.The were: T1; Cow dung applied at 10 t ha -1 dry mass (10 DM ), T2; Poultry manure, T3; Pig T4; Control, unamended...

Research on the resistance of cassava to fire is scarce because ordinarily researchers would not set their farms for such evaluation.Stems rendered useless by were commonly reported farmers but no information root yields and shoot regeneration.This study compared superiority two improved International Institute Tropical Agriculture (IITA) varieties ("Yellow root" "Agric") over plantain moringa in a + intercropping arranged randomized complete block design at University Nigeria, Nsukka,...

The study determined rice farmers’ perceived resilience capacity to climate change in Ebonyi State, Nigeria. Multistage sampling procedure was employed selecting 104 respondents for the study. Data were collected using semi-structured interview schedule. Percentage, mean and standard deviation used presentation of results. Results showed that areas were: planting improved varieties seed ( x̄ =4.76), utilisation soil retains water longer =3.33), access very fertile production =3.28) good...

The present study assessed the effect of quarrying on topsoil lead deposit and selected soil fertility indices lowland rice fields in Ishaigu, Ebonyi State.A purposeful sampling technique was used selecting locations evaluated this study.The were: Danger zone, which is where industrial waste waters/ effluents are discharged to, Ngwogwo Okue mining areas, while Ovumte served as control location.Two sets factors four (Factor A) constitute main plot three toposequence positions (upper, middle...
