In wheat cultivation, sowing frequency is one of the crucial agronomic applications affecting grain yield. The aim of the research was to determine the effects of application of different sowing frequency (350, 500, 650 and 800 seeds m-2) for bread wheat cultivars (Alpu 01, Atay 85, Bezostaja 1, Harmankaya 99, Sönmez 01 and Sultan 95) on yield and yield components. Trials was carried out in Transitional Zone Agricultural Research Institute Eskişehir central campus fields during at 2012-13 and 2013-14 crop seasons in irrigated and rain fed conditions with 3 replications in randomized complete blocks design. In this study, the factors such as grain yield, number of spike per square meter, spike length, number of grain per spike, weight of grain per spike and harvest index were examined in terms of sowing frequency applications and cultivars in both conditions. As a result, the maximum grain yield was obtained from 650 seeds m-2 in rainfed conditions and this value was obtained from the application 500 seeds m-2 in irrigated conditions. Harmankaya_99 variety reached the highest values in terms of grain yield in both conditions and followed this by Alpu01 variety. In both conditions spike length, number of grain per spike, weight of grain per spike and harvest index parameters decreased inversely with increasing sowing frequency, while the number of spike number per square meter increased in direct proportion to increased sowing frequency. In rainfed conditions while there was a positive correlation between the grain yield with number of spike per square meter and harvest index, there was negative correlation among grain yield with spike length, number of grain per spike and weight of grain per spike. There was found significant positive correlation between grain yield with spike length and harvest index in irrigated conditions.

Newcastle disease (ND) is one of the major viral diseases of poultry, remains a constant threat in poultry farms that causes huge economic losses every year. However, little is known regarding the potential risk factors of the disease in broiler. The study was undertaken to ascertain the potential risk factors and biosecurity measures in ND prevalent broiler farm. A total of 116 broiler farms were considered as a sample size from a different area of Barishal district of Bangladesh in which 19.83% ND prevalence was found. In the findings, the farmers (33.62%) who had training on poultry farming, were significantly less ND positive case (7.69%). Besides this, among the different risk factors and biosecurity measures only shed location, ventilation, vaccination status, feeder and waterer cleaning frequency, visitors accession, pets in the farm, use of disinfectant and seasonal variation had significant effect on ND outbreak. However, among all the factors only farmers training (OR=0.025; 95% CI: 0.001-0.509), shed location (OR=0.035; 95% CI: 0.003-0.390), vaccination against ND (OR=0.017; 95% CI: 0.001-0.435) and use of disinfectant daily (OR=0.011; 95% CI: 0.000-0.294) made a unique statistically significant contribution to the regression model and the predictors had approximately similar strength on reporting ND outbreak. In completion, ND can be reduced in broiler farms by improving the level of common biosecurity, farm management practices, and minimizing the potential risk factors through training of farmers, awareness build-up, and enforcement of these practices on the farms.

Most poultry farmers in Nigeria feed their laying birds twice a day with one bag of 25 kg to 200 layers which translate to 125g/bird/day, while very few feed once or thrice a day and there has been little or no documentation on how many times laying hens should be fed in a day to optimize profit. Thus, this study was designed to investigate the performance and egg qualities of Isa-Brown layers fed different quantities of feed at varying feeding frequencies. Three hundred and sixty (360) 16-weeks in-lay Isa-Brown layers were used in this trial. The treatment consisted of 95g, 105g, 115g, and 125g of feed per day at varying frequencies of once, twice and thrice per day. The birds were housed in California type cages, 3 birds per cage unit, 5 cage units per replicate, and 6 replicates per treatment. A completely randomized experimental design with a 4x3 factorial was adopted. Results at the end of the trial showed that bird fed 115g of feed twice per day had the highest percentage hen-day production (85.24%), highest egg mass (56.69g) and best feed conversion ratio (1.96) while lowest percentage hen-day production (62.02%) and lowest egg mass (39.22g) were observed in hen fed 95g of feed thrice per day and worst feed conversion ratio (2.50) was recorded in bird fed 125g of feed thrice per day. The bird fed 115g twice per day had the highest net profit (N637.63) while the lowest net profit (N199.33) was recorded in bird fed 125g thrice per day. It could be concluded that for optimum laying performance and to save time and labour expended in feeding birds thrice per day, feeding laying Isa-Brown birds the required feed quantity (115g) twice per day would be most economical.

The trials were set up in Busia, Embu and Kirinyaga Counties to assess the effect of tillage methods and application of different fertilizer combinations on maize productivity in the lower and upper midland agro-ecological zones of Kenya. Tillage methods were no-tillage (NT) with crop residue retention as mulch (+CR) (NT+CR) and conventional tillage (CT) without crop residue retention on farm surface (-CR) (CT-CR) while fertilizer combinations were NK, NP, PK, NPK, and NPK+CaMgZnBS. The N, P, K, Ca, Mg, Zn, B and S nutrients were applied at the rates of 120, 40, 40, 10, 10, 5 and 26.3 kg ha-1, respectively. The trials were laid in a randomized complete block design with a split-plot arrangement and replicated three times. The results showed that maize leaf area index, plant height, aboveground biomass, crop growth rate, and grain yield were significantly higher under CT-CR than under NT+CR in most of the sites. The CT-CR system out-yielded NT+CR system by 0.3 t ha-1 and 0.6 t ha-1 maize grain in Alupe and Kirinyaga, respectively. However, NT+CR system out-yielded CT-CR system by 0.4 t ha -1 maize grain at Embu. Across all the sites, application of PK and NPK+ZnBMgCaS fertilizer combinations resulted, respectively, in lowest and highest maize shoot biomass, leaf area indices, crop growth rates, plant heights, and grain yields. Based on this result alone, the potential of conservation agriculture in improving yields compared to conventional tillage could not be conclusive despite consistently recording higher soil moisture content across all sites and better yields in Embu. Again, application of a wide range of nutrients may be beneficial to maize production in the study areas as evidenced in the study. Therefore, we recommend multi-season and multi-location trials to comprehensively assess the impact of tillage methods and fertilizer management, particularly in relation to micronutrients.
