A two-year field experiment was carried out to investigate the effects of nitrogen, composted manure, municipal waste compost, and weeds on yield and photosynthetic characteristics of corn. Experimental design was split split plot factorial with 3 replications. Main plots were weedy and weed-free, sub plots were nitrogen fertilizer levels [0 (N0) and 200 (N200) kg N ha -1 as urea], and sub sub ...

Continuous use of chemical fertilizers is detrimental to soil health and crop productivity. Therefore, we need recycle the agroresidues in valorized form (e.g., biochar or compost) improve quality while maintaining yield. This study compares different nutrient management practices using varied dose combinations biochar/compost for sustainable production rice. We present results from a controlle...

Selected in-®eld physical, chemical and biological indicators were measured for the rapid assessment of soil quality changes in a Sorrento silty clay loam as a result of compost and ammonium nitrate application to a broccoli ®eld (San Benito County, CA). Plots were laid out in a randomized complete block design with four replications of 0, 22 and 44 Mg haÿ1 compost treatments which were split t...

Problem statement: This experiment was carried out for study the effects of chemical and biological fertilizers and interaction between them on some physiological characteristic and yield and its components of seed corn in two different irrigation. Approach: The experiment was conducted in a split plot factorial with completely randomized block design using four replications. Sub plots consiste...

effects of organic manure (poultry manure) applied alone and integrated with inorganic fertilizer (urea) on yield and yield component, n-uptake and soil fertility in wheat-maize cropping system was evaluated in a field experiment at nuclear institute for food and agriculture, peshawar, pakistan. poultry manure was applied alone and were integrated in different proportions with mineral nitrogeno...

background and objectives: production and use of fertilizers in common agriculture have been many environmental problems. while the application of organic fertilizers instead of chemical fertilizers have a important role in soil fertility, increase quality of production and safety of agricultural ecosystems. pumkin, is an important annual herbaceous plant belongs to the cucurbitaceae family due...

in order to study the effects of drought stress and organic fertilizers (compost and vermicompost) on some physiological and biochemical characteristics of borage, an experiment with complete randomized block design in split plot arrangement with three replications was conducted in zabol university, zabol, iran. the treatments included 3 levels of stress as a witness or 100% of field capacity, ...

Shallot productivity relies on diverse environmental conditions, including soil fertility. Compost is an organic material that crucial for the improvement of health and amendment could be employed shallot to improve its growth productivity. This study aims investigate effect 4 different composts amendments, processed with bioactivators, (Bima–Brebes variety), dynamic culturable microbes, nutrie...
