abstract to evaluate the effect of different sources of p fertilizer on grain yield and yield components of two barely varieties, this experiment was conducted in research farm, college of agriculture, university of tehran in 2010. the experimental treatments were arranged as factorial based on randomized complete block design with three replications. the treatments consisted of two barely vari...

A field study was conducted to determine the effect of organic and mineral-based fertilizers on phytochemical contents in the tubers of two cassava varieties. Treatments were arranged in a split plot design with three replicates. The main plot was fertilizer source (vermicompost, empty fruit bunch compost and inorganic fertilizer) and sub-plot was cassava variety (Medan and Sri Pontian). The am...

In this study, nitrogen fertilizer was applied to corn (Zea mays L.) at conventional (excessive) and recommended levels, and the growth response was assessed by measuring plant height and stem perimeter. Corn plant maximum height was observed in recommended rates of N fertilizer treatment, and the height without N fertilizer was the same as that receiving excess N fertilizer. Stem perimeter was...

In this paper the variations across China of climate, other natural growing conditions and anthropogenic farm inputs are used as a natural experiment to identify the contributions of each to the production of corn, potatoes, rice, soybeans and wheat. Crop production functions are estimated across prefectures using land, labor, fertilizer, machinery and irrigation inputs, as well as estimates of...

Introduction The profitability of beef production is as many other production systems, a function of a balance between inputs and outputs. Outputs can be more easily defined than inputs and can be simplified as pounds of beef sold in one way or another: carcass, replacement heifers, yearlings, weaned calves. However, inputs can be more challenging to define and vary greatly with different produ...

Abstract This paper examined organic fertilizer adoption and its effects on two household food security indicators gender-based farm labor use among smallholder farmers in Northern Ghana. An endogenous switching regression analysis shows that observed unobserved farmer background factors determine farmers’ decision to adopt as well the outcomes from adoption. On average, is associated with an 1...

A n n u a l W h e a t N e w s l e t t e r V o l. 5 4. The 4-year average for the different fertilizer backgrounds indicated that the least total grain damage by cereal bug larvae was in the block with organic-mineral fertilizer, 5.6 %. Damage in the blocks without fertilizer and with only organic fertilizer was 5.9 and 6.0 %, respectively. Total damage was 4.2–4.9 % in seed with a score of 2, w...

This paper assesses the origins of and changes to fertilizer policy in Nepal over a period of time. It assesses farmers’ awareness of the recent changes to the subsidy policy and examines their perceptions of the extension services. This paper looks at the environmental implications of the concentrated application of chemical fertilizer, particularly as far as food security is concerned. Questi...
