A field study was carried out to evaluate the effects of tillage practices on soil physical properties in Mwala district, Eastern Kenya, during the long rains (LR) and short rains (SR) of 2012/13. The treatments were disc ploughing (DP), disc ploughing and harrowing (DPH), ox-ploughing (OX), subsoiling-ripping (SSR), hand hoeing with tied ridges (HTR), hand hoeing only (H). These were investiga...
β-glucosidase is involved in the degradation of cellulose in soil and has the potential for monitoring biological soil quality. the objective of this study was to determine the effects of barley residue placement, burning, nitrogen fertilizer and tillage management on β-glucosidase enzyme after a period of 90 days. a field experiment was carried out based on a completely randomized design with ...
The study aimed to determine the interference periods of weeds in cassava ‘IAC 90’ cultivated different cycles and cropping systems. An experiment was conducted period 2014/15 (1st cycle) another from pruning plants 2015/16 (2nd cycle). experimental design a randomized block with split-split plots four replicates. represented systems (conventional no-tillage) corresponded without coexistence (0...
Weed infestation is considered a significant yield reducing factor in maize around the world as well south Asia. Integrated weed management (IWM) recommended to reduce our reliance on synthetic herbicides and sustainable production. In this study, different tillage regimes various allelopathic treatments were integrated for spring planted at Agricultural Research Station, Swabi (KP), Pakistan d...
The effects of tillage methods and residual management on yield and yield components of rapeseed (Brassica napus L. CV. Hyola308) were evaluated after rice harvest. The experiment was carried out during 2004-2005 cropping season in a factorical arrangement of treatments at Rice Research Institute of Iran (RRII) in Rasht, in a Complete Randomized Block Design with three replications. Treatments ...
ABSTRACT The population density of the reniform nematode, Rotylenchulus reniformis, was monitored at depths of 0 to 30, 30 to 60, 60 to 90, and 90 to 120 cm in a tillage and crop sequence trial in south Texas in 2000 and 2001. Main plots were subjected to three different tillage systems: conventional tillage (moldboard plowing and disking), ridge tillage, and no-tillage. Subplots were planted w...
This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...
the aim of this study was to investigate the effect of tillage methods to obtain suitable seedbed for monogerm seed. therefore, a split plot experiment based on a randomized complete block design (rcbd) with three replicatians was conducted at darab station of fars province. the main plot was seedbed prepration at two levels including fall and spring season. subplot included 1) moldboard plow a...
A cover crop management trial in butternut squash was planted at the Forgotten Harvest Ore Creek Farm (9153 Major Rd, Fenton, MI 438430) in a Miami loam soil with a 02% grade. The objectives were to determine how yields following a cereal rye cover crop were affected by three tillage systems and three at-plant fertilizer treatments in a split-plot Randomized Complete Block Design with four repl...
to investigate the changes in yield and yield components of dry land wheat (triticum aestivum l. cv agosta), under the influence of residue and nitrogen levels and different tillage practices, a field experiment was conducted during the 2006-2007 growing season, in the agricultural research station of the college of agriculture, shiraz university, iran. the experiment was designed as a split-sp...
