در این رساله، طراحی، اجراء و مدلسازی فرآیند nano-edm مورد بررسی و تحقیق قرار گرفت. به منظور تولید نانو- ابزار مناسب برای فرآیند nano-edm یک دستگاه اتوماتیک طراحی و ساخته شد که با استفاده از آن، تاثیر متغیرهای فرآیند ساخت بر خصوصیات نانو- ابزار مورد تحقیق قرار گرفت. با شناسایی سطوح بهینه متغیرهای فرآیند ساخت به روش تاگوچی، نانو- ابزارهایی با شعاع نوک حدود 10 نانومتر و ضریب جانبی (نسبت طول به شعا...
Nanoscience coupled with nanotechnology emerged as possible cost-cutting approach to prodigal farming and environmental clean-up operations. Hence there is a need for more innovative fertilizer that can increase the productivity of agricultural systems friendly than synthetic fertilizers. The trial was laid out in randomized complete block design 11 treatments three replications. field experime...
The utilization of nano-sized nitrogen (N) and zinc (Zn) fertilizers through foliar application has gained considerable attention in agricultural research. This study focuses on investigating the effects such applications soil properties, including both chemical biological aspects, after harvest mustard (Brassica juncea L.). field experiment was carried out during October to March 2022 season a...
Nanomaterials have been developed for various applications due to their unique features, and anew interest is now growing in use the agricultural sector as nano-fertilizers. Among nanomaterials, hydroxyapatite nanoparticles (Nano-HAP) possess a relevant potential be used source of nano-phosphorus fertilizer. Here, we evaluated effect these on growth traits, herb essential oil yields, histologic...
Global climatic change leads to many detrimental effects on all life forms. Outstanding case, salinity, and drought are considered multidimensional stress that severely affect plant growth sustainable agriculture. Thymus vulgaris is a medicinal has phytochemical constituents, it threatened by several abiotic stresses caused climate change. Therefore, the present study aims evaluate physiologica...
Phosphorus (P) deficiency in soil limits crop yields and can be managed by P fertilizers. But mere applying fertilizers alone may not effective justifying its bioavailability. At present global reserves are declining an increasing way which urges us to find out alternatives. Thus, the work was taken prepare phosphocompost using water hyacinth (Eichhornia crassipes) as feedstock, termite, normal...
Pigeon pea (Cajanus cajan (L.) Mills.) is one of the major grain legume crops grown in the tropics and sub-tropics and accounts for about 5% of world legume production. It is the fifth prominent pulse crop in the world and second most important pulse crop after chickpea in India. India is ranking first having about 90% of the world area and 85% of production. Organic farming in recent years gai...
Microbial biomass nitrogen and carbon were studied in long-term field experiments with continuous cultivation of silage maize and with crop rotation. a positive effect of organic fertilizers on the microbial biomass nitrogen and the carbon content in soil was observed. Statistically significant effect of organic fertilizers on the higher content of microbial biomass C and n was established in t...
