Harvest time and storage had significant effects on nutrient quality Volatile Organic Compounds (VOCs) of alfalfa. The objective this study was to use headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) analyze alfalfa at different harvest periods (budding stage, early blooming, full blooming), for 0 d, 90 180 270 360 the dynamic changes in VOCs nutritiona...

A computer model calculates the dollar loss due to the presence of plains pocket gophers ( Geomvs buCsarius majusculus) in alfalfa fields. Five alternative control methods are then evaluated. Total cost, cost per acre, hours of labor, and economic feasibility are printed for each control method. The model serves not only as an immediate decision aid but also serves to simulate conditions that l...

this experiment was conducted to assess the effects of daytime cutting management (p.m. vs. a.m. cut), ensiling duration and adding microbial inoculants on chemical composition of alfalfa silage. for this, second growth alfalfa harvested at the early bud stage of development after a sunny day at sundown (about 1900 h; pm alfalfa), whereas the second half was cut next day at sunup (about 0800 h;...

before a killing freeze was imperative for winter survival and plant persistence. Cutting during cold hardening Harvesting alfalfa (Medicago sativa L.) after mid-September in lowered both plant persistence and root total nonstructhe North-Central USA often reduces plant winter survival, but the physiological mechanisms associated with poor winter survival are not tural carbohydrate (TNC) concen...

Bromus sect. Triniusa is revised in Khorassan based on the new taxonomic concepts of Bromus danthoniae complex group and a remarkable herbarium material collected from Khorassan (Kopetdagh, northeastern Iran), as the main center of its diversity. Bromus turcomanicus, a narrow endemic species in central Kopetdagh hitherto known only from the type locality in southern Turkmenistan, is newly recor...

Alfalfa (Medicago sativa L.) is one of the most relevant forage crops due to its importance for livestock. Timely harvesting critical secure adequate quality. However, farmers face challenges not only decide optimal time but predict optimum levels both production and Fortunately, remote sensing technologies can significantly contribute obtaining quality insights, providing scalability, supporti...

crop density measurement is one of the most important factors in precision farming and effect onthe performance of harvesting machines such as combine and mower. so, the purposes of this studyare to design, build and calibrate of an inexpensive and non-contact instrument that can estimatecrop density for crops such as wheat, barley and alfalfa stems. the sensing unit is consisted of lasertransm...
