Chickpea (Cicer arietinum L.) is one of the major legume crops grown in Pakistan having a considerable importance as a food, feed and fodder but due to imbalanced use of fertilizers its production is low. To find the optimum level of Phosphorus and FYM for chickpea and study their effect on agronomic characteristics an experiment was carried out at the Agricultural Research Farm of NWFP Agricul...

Tillage systems affect many properties of soil, such as soil bulk density, porosity, pore distribution, and water capacity. However, the effect reduced tillage (RT) on faba bean cultivation requires wider analysis. We carried out our investigations at Vytautas Magnus University, Agriculture Academy (Lithuania), part a long-term field experiment. The aim was to determine intensity distribution c...

Dryland wheat (Triticum aestivum L.) and grain sorghum (Sorghum bicolor (L.) Moench) are often grown using a wheat–sorghum-fallow (WSF) crop rotation on the semiarid North American Great Plains. Precipitation stored during fallow as soil water is crucial to the success of the WSF rotation. Stubble mulch-tillage (SM) and no-tillage (NT) residue management practices reduce evaporation, but the sp...

high intensity evaporation from the soil surface due to low air humidity and poor soil structure and organic matter are constraints of agriculture in arid and semi-arid regions of iran. regionally, maintaining plant residue with tillage management is one method to improve these conditions. in this study, for a barley-corn rotation, four barley residue management methods for standing stubble (bu...

Soil N2O emissions from three corn (Zea mays L.)-soybean [Glycine max (L.) Merr.] systems in central Iowa were measured from the spring of 2003 through February 2005. The three managements systems evaluated were full-width tillage (fall chisel plow, spring disk), no-till, and no-till with a rye (Secale cereale L. 'Rymin') winter cover crop. Four replicate plots of each treatment were establishe...

In the Atlantic Coastal Plain region of southern Georgia (USA), cotton (Gossypium hirsutum L.) acreage increased threefold in the past decade. To more effectively protect water quality in the region, best management practices are needed that reduce pesticide runoff from fields in cotton production. This study compared runoff of two herbicides, fluometuron [N,N-dimethyl-N'-[3-(trifluoromethyl)-p...

A field investigation was conducted at Agronomy research farm A. S. (P.G) College, Lakhaoti, Bulandshahr during rabi seasons of 2006 and 2007. The treatments consisted combination four cropping systems viz. chickpea sole (M1), linseed (M2), chickpea+ 2:1 ratio (M3) pigeonpea + 4:2 (M4) in main plots; two irrigations vegetative stages (30-40 days) flowering stage (70-75 (S1) one irrigation (S2) ...

long season and high temperature during spring in hot and dry areas has led to tendency for autumn planting. in order to evaluation of chickpea (cicer arietinum l.) autumn planting possibility, a field experiment was done at the agricultural faculty and natural resources of saravan research field in 2010. experimental design was done as split plots based on randomized complete block design with...

Investigating microbial metabolic characteristics and soil organic carbon (SOC) within aggregates and their relationships under conservation tillage may be useful in revealing the mechanism of SOC sequestration in conservation tillage systems. However, limited studies have been conducted to investigate the relationship between SOC and microbial metabolic characteristics within aggregate fractio...

to evaluate the effect of cover crops, tillage systems and nitrogen (n) application rates on yield of forage sorghum (cv. kfs3), a factorial–spilt plot arrangement based on randomized complete block design with four replications was carried out at the research farms college of agriculture and natural resources, university of tehran, karaj, during the growing seasons of years 2005 and 2006. comb...
