The goal of sustainable intensification of agriculture in Malawi has led to the evaluation of innovative, regionally novel or under-utilized crop species. Quinoa (Chenopodium quinoa Willd.) has the potential to provide a drought tolerant, nutritious alternative to maize. We evaluated 11 diverse varieties of quinoa for their yield and agronomic performance at two locations, Bunda and Bembeke, in...

in order to study the effects of manganese sulfate in increasing seed yield of four safflower genotypes (carthamus tinctorius) under rainfed conditions, this experiment carried out in maragheh agricultural research station. the experiment was arranged with four mn fertilizer levels (0,10,20,30 kg ha-1) as soil application together with two foliar spray levels (1% and 2%) of 1.5 kg ha-1 manganes...

Delay of leaf senescence through genetic modification can potentially improve crop yield, through maintenance of photosynthetically active leaves for a longer period. Plant growth hormones such as cytokinin regulate and delay leaf senescence. Here, the structural gene (IPT) encoding the cytokinin biosynthetic enzyme isopentenyltransferase was fused to a functionally active fragment of the AtMYB...

this study was conducted to determine grain yield stability of rainfed promising barley genotypes across six rainfed research stations (maragheh, sararood, uromieh, qamloo, zanjan and ardabil) under cold and semi-cold conditions during three cropping seasons (2006-2009) in iran. the studied genotypes were 10 promising barley lines along with two checks (one local and one newly released variety,...

As planetary boundaries are rapidly being approached, humanity has little room for additional expansion and conventional intensification of agriculture, while a growingworld population further spreads the food gap. Ample evidence exists that improved on-farmwatermanagement can close water-related yield gaps to a considerable degree, but its global significance remains unclear. In this modeling ...

Groundnut (Arachis hypogaea L.) is an important oilseed crop grown in our country. Majority of crop is under rainfed conditions and as a post rainy season (Rabi) crop in Andhra Pradesh. Several models are available to predict the phenology, growth and yield of groundnut crop. However, no precise models are available to validate the effects of moisture stress on groundnut and their subsequent im...

This article assesses sugarcane yield gaps (YG) in Brazil to determine the degree to which production can be increased without land expansion. In our scenario assessments, we evaluated how much of the projected sugarcane demand to 2024 (for both sugar and bioethanol) can be satisfied through YG closure. The current national average yield is 62% of yield potential estimated for rainfed condition...

To help farmers in the mid hills of Nepal improve their crop management and rice yields, we conducted a study testing different nursery management options and their effect on grain yield and yield components under rainfed conditions. The experiment was conducted in a farmer’s field during the cropping season 2009 and 2010 at Sundarbazar, Lamjung, Nepal, using a 3-factor factorial RCB design wit...
