drought stress, especially drought at terminal stages, plays an important role in reduction of yield in field crops such as common beans. 50 genotypes of common bean including 3 control genotypes (dehghan, bahman and naz) were used to evaluate and identify the tolerant genotypes. this experiment were performed in a randomized complete block design (rcbd) with three replications under two condit...

Organic farming is known to be the production system where synthetic fertilizers and pesticides are largely or completely avoided, it has been observed recently rapid growth of in last decades. An experiment was conducted at Vegetable Research Farm National Horticultural Institute, Ibadan, Oyo state determine influence rabbit urine as organic fertilizer on yield two varieties cucumber. The laid...

the measurement of wheat crop yield in large areas is time consuming and requires high expenses. one way to save time and cost, using geostatistical methods for mapping crop yield. in this research principle component analysis were used for identifying variables that have correlation with each other, and kriging and cokriging were used to map crop yield prediction. fourty six samples were used ...
