Zambian farmers have extensive experience with maize hybrids and input subsidies. Like other countries in Eastern and Southern Africa, the successful development and diffusion of improved maize seed in Zambia during the 1970s and 1980s was supported by strong government commitment to parastatal grain and seed marketing and subsidized provision of services to maize growers. When this system was ...

demographic parameters of the pink stem borer, sesamia creticalederer (lepidoptera: noctuidae) were estimatedon its two main host plants, maize and sugarcane. the present studywas conducted under laboratory conditions at 27±1˚c, 50±10% relative humidity (rh %), and a photoperiod of 0:24 (l:d) hour for the larval stage and 16:8 (l:d) hour for the other life stages. the raw data were analyzed bas...

The cytogenetic interactions in maize x Tripsacum hybrid derivatives can be remarkably complex. The number of viable, somewhat female fertile chromosome combinations is astonishing. Fifty-four different combinations are listed in this paper, and others are certainly possible. In successive backcrosses to maize, chromosome numbers scale both up and down with ease, sometimes stabilizing for a few...

The receptor for activated C kinase 1 (RACK1) belongs to a protein subfamily containing a tryptophan-aspartic acid-domain (WD) repeat structure. Compelling evidence indicates that RACK1 can interact with many signal molecules and affect different signal transduction pathways. In this study, we cloned a maize RACK1 gene (ZmRACK1) by RT-PCR. The amino acid sequence of ZmRACK1 had seven WD repeats...

Seams are very important for the quality of woolen garments. garment must be durable and smooth. Seam performance is an factor determining durability a garment. The tensile characteristics seamed fabric changes with change bias angle, stitch seam types. In this study, three wool fabrics different properties were chosen. Fabrics have been cut in angles 0°, 30°, 45°, 60° 90° then sewn six types (...

Castor is one of neglected African oil crops with little research attention in Nigeria. In the present research, eighty-six castor genotypes were evaluated at three locations in Niger State, Nigeria. The aim was to estimate the extent of genetic variability and also to examine the associations among the seed yield and its components. The treatments were laid out in an Alpha Lattice Design with ...

Intercropping systems compared to monoculture systems can more efficiently use the existing resources which ultimately will lead to increased plant performance. Therefore, to evaluate the benefits of intercropping maize and beans and assess its impact on yield and yield’s component, an experiment was conducted in factorial design with randomized complete block design in three replication, in 20...

Blanket recommendation of nitrogen (N) for maize would not be applicable as the new high yielding hybridshave been grown in Nepal. A field experiment was carried out during spring season at Badhaiyatal, Bardiya to determine optimum N level hybrid maize. The treatments consisted three commercial hybrids namely Rampur hybrid-10, Rajkumar and Pioneer-3522 four levels i.e., 150 kg ha-1, 175 200 ha-...

to evaluate the genetic diversity in sardari bread wheat landrace, purification and selection of lines with good agronomic traits, were carried out for ten cropping seasons (1995-2006) in maragheh and six other dryland agricultural research stations. one hundred and six individual spikes were selected among sardari landrace in the first phase of study (1995- 2000). results of morph-physiologica...
