Energy requirements for seedbed preparation and planting systems of mungbean crop under Egyptian conditions [electronic resource].

Includes references.

The aim of this work was to study the energy requirements for seedbed preparation and planting systems of m1Ulgbean crop (Kawmy-l variety). To achieve this goal the following systems were used and tested: SIP}: chisel plough (one pass) followed by land leveler and seed drill, S1P2: chisel plough (one pass) followed by land leveler and manual broadcasting, S2P1: chisel plough (two passes) followed by land leveler and seed drill, S2P2: chisel plough (two passes) followed by land leveler followed by manual broadcasting, S3P1: mouldboard plough followed by land leveler and seed drill, S3P2: mouldboard plough followed by land leveler and manual broadcasting, SJI}: rotary plough followed by seed drill, and S.P2: rotary plough followed by manual broadcasting. The field experiments were carried in a loamy soil at the Researches Farm of Medicinal Plant, National Organization for Drug Control and Research, Ministry of Health, Kafr El-Gabal, Giza Government. The obtained results could be summarized as follow: The system of (S4P1) gave the lowest value of energy requirements per unit area(59.16 kW.h/fed.). But the system of (S2P2) gave the highest value of energy requirements per unit area (290.75 kW.h./fed.). The system of (S4P1) gave the lowest value of energy requirements per kilogram of seed yield (0.07 kW.h./kg). But the system of (S2P2) gave the highest value of energy requirements per kilogram of seed yield (1.17kW.hJkg). The system of (S2P1) gave the lowest value of cost per unit of energy requirements (0.83 L.E./kW.h) but the system of (S4P2) gave the highest value of cost per unit of energy requirements (1.06 L.E/kW.b). It am be recommended that the system of (S4P1) (rotary plough followed by seed drill) for mungbean crop production under condition of the experiment.
