Effect of micronutrient application in coriander (Coriandrum sativum L.) cv.CO4

The field experiments were conducted during two seasons to find out the role of micronutrients on growth, seed yield and quality in coriander cv. CO4. The soil of the experimental site was calcareous. Micronutrient deficiencies are common in soils that have a high calcium carbonate (CaCO3) due to reduced solubility at alkaline pH values. Micronutrients such as iron (Fe), zinc (Zn), copper (Cu) and manganese (Mn) were...

Agronomic and economic evaluation of the N and P response of bread wheat grown in the moist and humid midhighland vertisols areas of Arsi zone, Ethiopia

Field experiment was conducted in 2012 and 2013 in three districts of Arsi zone, Oromia region, Ethiopia to evaluate the response of bread wheat cultivar “Damphe” under highland vertisols to treatments consisting of 20 factorial combinations of five N rates from urea and four P205 rates from triple super phosphate (TSP). The treatments were laid out in RCBD, replicated three times. All data were subjected to...

Urban farmer practices in soil fertility and water management and the influence of gender in Harare and Chitungwiza, Zimbabwe

Poor soil fertility and increased frequency of mid-season droughts have made it difficult for urban farmers to get sustainable crop yields against a background of unemployment and reliance on urban agriculture for livelihoods in Harare and Chitungwiza. It is important to know soil fertility and water management practices used by urban farmers so that their performance can be evaluated and gender influence on their use...

A comparison of predicted and measured pesticides concentrations in runoff of cotton farms in Brazil

The adjustment and evaluation of methods which allow estimation of runoff and the concentration of associated pesticides are important for the development of prognostics studies in agricultural areas, mainly in tropical regions. In this context, this study aimed to adjust a method to estimate the concentration of pesticides in run-off applied to a cotton plantation farm, located in the micro-region of Primavera do Leste...

Growing degree-day sum and crop growth cycle duration for wheat cultivars at different sowing dates

The wheat Triticum aestivum L. is one of the most important foods in the human diet due to its high nutritional value. The grains can be eaten as bread, noodles, pasta, cookies, among others. The cultivation of wheat in Brazil has high production potential; the southern is region responsible for the largest acreage in the country, due to its soil and climate more favorable for crop development. The objective of this...

Green corn grown in succession to pigeon pea fertilized with phosphorus sources and lime

The practice of using green manure provides for the better utilization of chemical fertilizers and a lower cost of mineral fertilizers, and it promotes an increase in the soil’s biological activity. Green house experiment was conducted to evaluate the effect of different phosphorus sources and lime on pigeon pea growth and their effects as green manures on the dry matter production of green corn. The experiment...

Carbon and nitrogen stocks under different management systems in the Paraiban “Sertão”

The change in land use leads to significant changes in carbon (C) and nitrogen (N) stocks in the soil and consequently in the global cycle of these elements. The purpose of this study was to evaluate C and N stocks in soils under different management systems in the Paraiban “Sertão”.  This study was carried out in the watershed of Val Paraiso stream, State of Paraiba, Brazil. The climate is warm...

Effect of nitrogen fertilization associated with inoculation of Azospirillum brasilense and Herbaspirillum seropedicae on corn

The growing interest in the use of inoculants with diazotrophic bacteria that promote plant growth, providing increase in crop productivity, occurs because of the high costs of chemical fertilizers and the concern about environmental quality. Given the above, this study aimed to evaluate, in field conditions, the effect of nitrogen fertilization and inoculation with Azospirillum brasilense and Herbaspirillum seropedicae...

Effects of organic and inorganic soil amendments on growth performance of plantain (Musa paradisiaca L.)

A field experiment was conducted to investigate the comparative effects of organic and inorganic soil amendments on growth and performance of plantain (Musa paradisiaca). The experiment was established in March 2011 and repeated in February 2012. The treatments consisted of nine soil amendments (NPK sole, Jatropha sole, palm kernel cake (PKC) residue sole, Sunshine organo-mineral sole, NPK + Jatropha husk 50:50,...

Soil physical attributes under different grazing management of winter forage crops in crop-livestock system at Southern Brazil

The effects of different species and grazing management of winter forage crops on the physical properties of a clayey Red Latosol of the western region of Parana State under crop-livestock integration systems were investigated in the present study. Treatments consisted of three different winter crops [white oat (Avena sativa), dual-purpose wheat (Triticum aestivum) and triticale (X Tritico secale)] and three grazing...
