Purpose: Integrated and organic nutrient management has recently become the focus in Sri Lanka for seeking better perspectives on food quality environmentally friendly production. This study was conducted to understand magnitude of yield components under selective systems major cropping seasons within transitional period a conventional rice-based system. Research Method: Rice were measured with...
There are human and animal health concerns related to drainage systems because nutrients, especially nitrogen and phosphorus, can contaminate water supplies. A field study was conducted on consolidated paddy fields of Sari Agricultural Sciences and Natural Resources University, Northern Iran (36.3°N, 53.04°E), to determine the effect of subsurface drain depth and spacing on nitrogen (N) and pho...
In order to identify drought tolerant chickpea genotypes, an experiment was conducted in the west of Iran, during 2007-2009 cropping seasons. Several selection indices were used to illustrate genotypic differences in response to drought stress. The results of combined analysis of variance showed that year, genotype, stress conditions and their interaction effects were highly significant. Correl...
Time series data on cropping pattern at disaggregated level were analysed and its implications on geospatial drought assessment were demonstrated. An index of Cropping Pattern Dissimilarity (CP-DI) between a pair of years, developed in this study, proved that the cropping pattern of a year has a higher degree of similarity with that of recent past years only and tends to be dissimilar with long...
Line WB73-6 (Trompillo, CMB74A-432-25B-1Y-IB-1Y-OB) was first introduced in Iran through a nursery received from CIMMYT in 1989. It was selected in a preliminary experiment in Zabol research station among the genotypes of IBON in 1990. In other preliminary and advanced yield trails carried out in Zabol and other stations in southern provinces of Iran with warm climate in 1991-1997, line WB73-6 ...
Abstract Cropping of rice and wheat ( Triticum aestivum L .) in rotation contiguously the same field is a fundamental pillar double-cropping systems southern China. Yields such cropping are increasingly challenged as climate change (CC) drives increases autumnal rainfall, delaying harvesting subsequent sowing wheat. Here, our purpose was to identify prospective traits crops enabling adaptation ...
BACKGROUND Harnessing beneficial microbes presents a promising strategy to optimize plant growth and agricultural sustainability. Little is known to which extent and how specifically soil and plant microbiomes can be manipulated through different cropping practices. Here, we investigated soil and wheat root microbial communities in a cropping system experiment consisting of conventional and org...
The response of inbred maize (Zea mays L.) lines to nitrogen (N) fertilizer and cowpea (Vigna unguiculata cv. Iron Clay) cover cropping was evaluated in three consecutive croppings from 2014 2016 a Guamaní (Torrifluventic Haplustepts) soil. crop rotation sequence (spring 2014), (summer (winter 2014-2015), 2015), 2015-2016) 2016). N levels were 0, 90, 135, 180 225 kg N/ha for 2014-2015 seasons, ...
Soil biological quality can affect key soil functions that support food production and environmental quality. The objective of this study was to determine the effects of management and time on soil biological quality in contrasting dryland cropping systems at eight locations in the North American Great Plains. Alternative (ALT) cropping systems were characterized by greater cropping intensity (...
