Conservation Agriculture (CA) is still a relatively new approach for intensively cultivated (3 crops yr -1 ) rice-based cropping systems that produce high crop yield and amounts of residues annually. With the recent development transplanting rice into tilled strips on non-puddled soil, CA could become feasible patterns. However, effect increased retention response to nitrogen (N) fertilization ...
In order to evaluate the benefits of maize, pinto bean and naked pumpkin triple cropping, an experiment was carried out as a randomized complete block design with three replications at Faculty of Agricultural Science, University of Guilan, Rasht, Iran in 2012. The treatments consisted of maize, pinto bean and naked pumpkin sole cropping (100, 75 and 50% of conventional densities), maize – pinto...
introduction with the continuous growth of world population, degradation and ecological imbalance throughout the world, there is a need to increase agricultural production and environmental protection measures. in this respect, efforts to supply nutrients to the environment are at the head of the programs. one of the ways to approach this goal is the use of intercropping systems (najafi & moham...
in order to study the weeds frequency and dry matter in corn and cowpea sole cropping and intercropping systems, an experiment using replacement and additive techniques was conducted using different combination of intercropping in seven levels with ratio of 1:1 (50% corn + 50% cowpea), 1:2 (33% + 67%), 2:1 (67% + 33%), (100% + 20%), (100% + 10%), 100% corn and 100% cowpea, two levels optimal an...
This study was conducted to determine the effects of different intercropping design maize/soybean compared with sole cropping, in combination Vitormone (biofertilizer; Azotobacter) during 2012 and 2013. There were four designs used experiment: i) maize soybean, ii) 1 + soybean alternate rows, iii) 2 soybeans rows iv) intra under control application. The experiment laid out a randomized complete...
This paper considers the potential problems that may militate against the adoption of organic poultry production in Nigeria. Factors identified include: higher risk of diseases like coccidiosis and Newcastle disease, disease prevention and control / herd health management, disease containment in times of outbreak, land acquisition (land tenure system), market economies / cost-benefit ratio, pas...
