INTRODUCTION In an extensive review of organic mulches applied on conventionally tilled (plow-disk) fields, Dutton (1957) concluded: 1) that organic mulches such ashay and straw often increasedboth yield and quality of Irish potato (Solanum tuberosum L.) and 2 ) that improved soil physical properties under the mulch, particularly lower soil temperatures and conservation of soil moisture, were r...

in order to estimate heritability and gene action for grain yield and its related traits in lentil, six basic generations were evaluated in a randomized complete block design with three replications in a field experiment. besides seed yield per plant, plant height, pod length, and 100-seed weight, the number of pods per plant, primary branches, clusters per plant, nodes per main stem, secondary...
