Agricultural systems based on crop rotations favour sustainability of cultivation and productivity of the crops. Wheat-forage crops rotations (annual winter binary mixture and perennial alfalfa meadow...
This study investigates production efficiency of hazelnut farmers located in the Carsamba Plain, Samsun-Turkey. A sample of 78 farmers was selected by a two-stage sampling process. Data Envelopment An...
The effects of application of N fertilizer on wheat on the grain yield and N use efficiency (FNUE) of rice in the wheat-rice rotation system, as well as on the soil fertility were studies. N-fertilize...
Water deficiency is one of the primary yield-limiting factors in rice. In plants, the nutrition and water use efficiency depend on root growth efficiency under different water supply conditions (WSC)....
A field experiment was conducted to study water use efficiency and agronomic traits in rice cultivated in flooded soil and non-flooded soils with and without straw mulching. The total amount of water ...
The determinants of yam production in Southeastern Nigeria were investigated using a stochastic frontier production function, which incorporates a model of ineffi ciency effects. Farm-level data were ...
This study assessed the technical effi ciency of family poultry production in Niger- Delta, Nigeria. The technical effi ciency estimate shows that the technical effi ciency of family poultry ranges be...
The paper presents the influence of the conventional ploughing tillage technology in comparison with the minimum tillage, upon the soil properties, weed control, yield and energy efficiency in the cas...
