documenting the production process in agriculture includes providing all information and activities that shows the course of production from seedbed preparation stage to harvest stage. for this purpose, in present investigation all management operations performed from seedbed preparation stage to harvest stage in the studied wheat fields in 2007 and 2008 were recorded through farms survey. in t...

in this study an innovatively designed tractor-mounted, ground-wheel driven, triple unit, row crop precision planter capable of planting three rows of garlic (allium sativum l.) cloves on each raised bed was designed, fabricated and tested. the major components of this planter include; chassis and transport wheels, lister-bedder unit, seed hopper, seed metering drum, sweeper, knocker, seed tube...

N-propylsalicylidene based on silica as ion exchanger (IE) was used for the separation by complexation of Mn2+, Co2+, Ni2+, Cu2+, Hg2+, Cr3+, Fe3+, and UO22+ from their parent solutions. IE and its metal complexes are characterized by elemental analysis, electronic and infrared spectra, in addition to thermal analysis in atmospheric pressure. The mode of chelation and the proposed geometric str...

(Pinus taeda L. and P. echinata Mill., respectively) seed crops were monitored for 20 consecutive years (1980-1981 through 1999-2000) using seed-collection traps in natural stands on the Upper Coastal Plain qf southeastern Arkansas. Each seed-collection period began on October 1 and continued through the end of February of successive years . Sound seeds were separated,fiom void seeds by use of ...

We demonstrate the preparation of heralded Fock-basis qubits (a|0〉+b|1〉) from transient collective spin excitations in a hot atomic vapor. The preparation event is heralded by Raman-scattered photons in a four-wave mixing process seeded by a weak coherent optical excitation. The amplitude and phase of the seed field allow arbitrary control over the qubit coefficients. The qubit state is charact...

Native grasses are increasingly popular and valuable tools for revegetation, erosion control, and wildlife habitat improvement. Many have unique features and benefits that make them advantageous over certain exotic and introduced grasses. In the field of ecological restoration, they are a critical and required component of the target plant community, ecosystem, or natural habitat. A number of n...

A field experiment was conducted at Cotton Research Station, Nanded (M.S.) India during kharif season of 2019 and 2020 to study effect moisture conservation practices fertilizer levels on earliness Bt cotton under rainfed condition. The trial with hybrid NHH 44 (BG II) in split plot design replicated thrice. Four treatments (M1- flat bed, M2- opening furrow 60 DAS, M3- application superabsorben...
