Production of liquid fertilizer by fermented livestock liquid and application on crops

The livestock liquid commonly contains humic acid, amino acids and minerals; hence, it can be used for the fertilization of crops. These studies were conducted to examine the use of livestock fermented liquid in producing liquid fertilizers and irrigation application on two kinds of crops (tomato and wax apple). The experiments were designed as common liquid fertilizer and diluted by groundwater (CF), fermented...

Effects of combined salt and flooding stresses on the growth and physiological behavior of alfalfa (Medicago sativa L.)

The present work focused on evaluation of the physiological and metabolic behavior of alfalfa (Medicago sativa L., var. Siriver), when faced with two important ecosystems constraints, namely salinity and flooding-associated hypoxia. After germination, seedlings in symbiosis with Sinorhizobium meliloti were grown on different salt concentrations (0, 20 and 50 mM NaCl). At four weeks post-germination, plants were...

Severity and prevalence of the destructive fall armyworm on maize in Uganda: A case of Bulambuli District

Maize kernel contains a large quantity of carbohydrates, proteins, vitamins, oils, fats and competes favorably with root and tuber crops as a rich energy source. In Uganda, the per capita consumption ranges from 28 to 125 kg per annum. However, the yields remain low, fluctuating around 1.5 tons per hectare. Although some losses to maize production occur through the post-harvest period, pre-harvest factors such as biotic...

Potential of reduced agricultural lime application rates to increase yield and profitability of maize through microdosing in central Malawi - A short note

Maize (Zea mays L.) is a staple food crop in Malawi, with average yields of 1.8 -2.2 t ha-1 compared to potential yields of 5 to 10 t ha-1. In some areas, soil acidity is a serious constraint in crop production. The current recommendation is to apply 2.0 t ha-1 of lime as pre-plant broadcast and incorporated into soils with pHW < 5.5. A pilot study was conducted during 2015/2016 season at Bunda Campus (14° 35...

Role of leaf rolling on agronomic performances of durum wheat subjected to water stress

In arid and semi-arid climates characterized by low rainfall with a great annual and inter-annual irregularity, drought can occur at any time inducing large losses in crop yield. Leaf rolling is one of the adaptive morphological responses to the water deficit observed in a number of species including cereals. It reduces the leaf area exposed to sunlight and transpiration. The aim of the present work was to characterize...

Fertilizer-nitrogen use optimization for Tef in South Wollo Zone of Ethiopia

Tef [Eragrotis tef] is a major staple cereal crop in Ethiopia but yields are low due to inadequate nutrient supply and other constraints. A field study was conducted in 2014 and 2015 in Jamma district of South Wollo Zone of Amhara Region to determine the economic optimum rate of fertilizer-N for tef. Fertilizer-N rates of 0, 23, 46, 69, 92, 115 and 138 kg ha-1 were evaluated. The randomized complete block design with...

Perception and uptake of aquaculture technologies in Kogi state, central Nigeria: imperative for Improved Management practices for sustainable aquaculture development

The drivers of perception and adoption of aquaculture innovations were studied. Data obtained from 300 aquaculture operators, were analyzed using Heckman Probit sample selection model. Results revealed that perception and adoption of aquaculture innovations were high. Education (a=0.281), extension contact (a=0.149), experience (a=0.021), gender (a=0.440) and information source (a=0.145) increased the likelihood of...

Comparison of laboratory methods in predicting the lime requirement of acid soil in Wombera District, North western Ethiopia

Soil acidity is one of the major constraints of crop production in the Ethiopian highlands where precipitation is high enough to leach basic cations leaving the soil acidic. Liming is the major practice used to ameliorate the problem of soil acidity. Currently farmers use Ag lime in their fields to reduce soil acidity. However, the suitability of the existing methods of lime requirement (LR) has not yet being...

Effect of different rates of filter cake against bruchids (Zabrotes subfasciatus (Boheman) and Callosobruchus maculatus (Fabricius) (Coleoptera: Chrysomelidae) on common bean and cowpea

Storage of common bean and cowpea is limited due to different species of bruchids. Zabrotes subfasciatus and Callosobruchus maculatus are the most important species of bruchids attacking stored common beans and cowpeas, causing yield losses reaching up to 38-100%. Two experiments, one on the effect of different rates of Filter Cake against Z. subfasciatus on common bean, and the other experiment on the effect of...

Comparison of yield performance and rice quality between direct-seeded and hand-transplanted rice under different nitrogen rates in Eastern China

In order to clarify whether the shift from hand-transplanting seedlings to direct seeding will bring negative effects to rice production and to find optimal nitrogen management for direct-seeded rice in Eastern China, research has been conducted in Quzhou City, in the Zhejiang Province of China in the year 2017 and 2018. One indica inbred rice variety, “Zhongjiazao-17” was planted by two different rice...
