Climatic constraints to crop production and fertilizer use

Modeling perceptions of climatic risk in crop production

In agricultural production, land-use decisions are components of economic planning that result in the strategic allocation of fields. Climate variability represents an uncertainty factor in crop production. Considering yield impact, climatic influence is perceived during and evaluated at the end of crop production cycles. In practice, this information is then incorporated into planning for the ...

Fertilizer production functions in relation to weather, location, soil and crop variables

Assess Effect of Nitrogen Fertilizer and Phosphorous Biofertilizers (Azospirillum and Pseudomonas) on Barley Crop Production and Seed Protein Content

BACKGROUND: Azospirillum is effective in biostabilization of nitrogen and Pseudomonas is effective in dissolving soil phosphorus. OBJECTIVES: Current study was conducted to assess effect of different level of nitrogen and biofertilizer on seed yield, its components and protein content. METHODS: This research was carried out via spilt plot fac...

Low-Input Cropping Systems and Nitrogen Fertilizer Effects on Crop Production: Soil Nitrogen Dynamics and Efficiency of Nitrogen Use in Maize Crop

Soil N is a major factor limiting crop production in maize-based agriculture in the tropics. In this study, soil N dynamics and efficiency of N use by maize was investigated in five cropping systems (CSs) over two annual cropping phases. The CSs comprised cereal-legume (CS1, CS2, CS3), cereal-cereal (CS4) and cereal-bare fallow (CS5) rotations with three rates of N fertiliser application to mai...

Investigation Growth Indices Analysis and Sorghum ( Sorghum bicolor L.) Crop Production Affected Different Level of Nitrogen and Nitroxin Bio-Fertilizer

BACKGROUND: Bio-fertilizers being essential components of organic farming play vital role in maintaining long term soil fertility and sustainability.OBJECTIVES: Study yield and growth indices of sorghum in response to consume chemical fertilizer and Nitroxin bio-fertilizer.METHODS: This research was conducted via split plot experime...
