Grain legumes are valuable sources of protein and contribute to the diversification sustainability agricultural systems. Shifting sowing date from spring autumn is a strategy address low yields grain under conditions climate change. A two-year field experiment was conducted Pannonian in eastern Austria assess nitrogen yield biological N2 fixation winter peas faba beans compared their forms. The...

The purpose of the research is to identify trends and factors variability in yield main agricultural crops Kirov region. study was conducted on basis data from territorial body Federal State Statistics Service for region 2001-2020. An analysis regression equations showed that dynamics analyzed period most accurately described by a 2nd degree polynomial. grain leguminous over twenty-year varied ...

A field experiment was conducted during kharif season of 2010 and 2011 to investigate the optimization of nitrogen levels under different age of seedlings transplanted on growth, chlorophyll content, yield and economics of hybrid rice. Fifteen treatment combinations consisted of three levels of seedlings age (10, 20 and 30 days) and five levels of nitrogen viz. N0, N50, N100, N150 and N200 kg h...

Low soil fertility and high weed infestation are the main culprits for the declining maize production inWestern Kenya. Technology packages to address these constraints exist, but their effectiveness is likely to be influenced by variability in soil types and farm management practices in the region. Trials were conducted during the 2008/2009 cropping seasons to investigate the nutrient use e...

Rotation, tillage, and variety main effects on grain yield were all significant in 2002. Rice grain yield, over all treatment combinations, averaged 159 bu/acre, which was 22 bu/acre more than in 2001. Grain yields for the two 3-phase rotations were 180 bu/acre for the rice-corn-soybeans rotation and 177 bu/acre for the rice-corn (wheat)soybean rotation. These yields were slightly better than t...

in order to evaluate the effects of row spacing and seed rate on yield and yield component of common bean (phaseolus vulgaris l.) cultivars, a split plot factorial experiment based on randomized complete block design with 3 replications was conducted at second crop research station of rice research institute of iran (rasht) during 2008 and 2009. experimental factors were row spacing in three le...

Nitrogen (N) application management needs to be refined for low yielding environments under dryland conditions. This 3-yr study examined nitrogen fertilization management effects on corn (Zea mays L.) plant characteristics and grain yield in rain fed environment under conventional tillage system. Nitrogen fertilization management consisted of two timing methods of N application [all N at planti...

Genotypic variation in ear morphology is linked to differences in photosynthetic potential to influence grain yield in winter cereals. Awns contribute to photosynthesis, particularly under water-limited conditions when canopy assimilation is restricted. We assessed performance of up to 45 backcross-derived, awned-awnletted NILs representing four diverse genetic backgrounds in 25 irrigated or ra...

NT will reduce soybean grain yields and economic returns, particularly during the first few years of adoption. Farmers have been encouraged to adopt no-tillage (NT) because Soybean grain yield response to NT systems depends of its positive environmental effects compared with other conservation tillage systems. Nevertheless, poor crop performance under NT manmainly upon soil drainage and previou...
