Adaptation of Small-Seeded Red Lentil (Lens culinaris Medik. subsp. culinaris) to Diverse Environments
The lentil improvement program of ICARDA benefits from the information generated by the Legume International Nursery Network operating globally. Over the period 1996 to 2002, 12 different types of trials comprising lentil ...
Forage and Food Legumes in a Multi‐Year, Wheat‐Based Rotation Under Drought‐Stressed Conditions in Northern Syria’s Medium Rainfall Zone
Long-term crop rotation trials were designed to assess sustainability of alternatives to traditional fallow and monocropping. The trial described here (6 years) involved wheat (Triticum aestivum L.) in rotation with lentil ...
Statistical estimation of time-trends in two-course crop rotations
An assessment of time-trends in yield parameters is essential to the utilization of data from long-term field trials for the comparison of different crop rotations and input regimes, and the identification of sustainable ...
Estimating time to detect time trends in continuous cropping
In long-term field trials comparing different sequences of crops and husbandry practices, the identification and understanding of trends in productivity over time is an important issue of sustainable crop production. This ...
Crop sequences, nitrogen fertilizer and grazing intensity in relation to wheat yields in rainfed systems
The Mediterranean region is experiencing unrelenting land-use pressure, largely driven by population growth. Long-term cropping system trials can guide crop and soil management options that are biophysically and economically ...
Modeling unstructured heterogeneity along with spatially correlated errors in field trials
In this paper we consider analysis of two experimental data sets for evaluating lentil genotypes. One of these data sets comes from an incomplete block design and the other one from a complete block design. The incomplete ...
