A field experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University (BAU), Mymensingh during Aman season of 2011 to evaluate the effects of manures and fertilizers for maximizing the yield of BRRI dhan49. The experiment had six treatments, laid out in a randomized complete block design (RCBD) with four replications. The treatments were T0 = Control, T1 = ...

Two field experiments were carried out during the summer seasons of 2001 and 2002 at the Experimental Station Farm of the Faculty of Agriculture, Alexandria University, at Abeis, to study the effects of four treatments of organic manure (unmanured, chicken, compost and cattle) and three biofertilizer treatments (uninoculated, Halex 2 and Nitrobein) on vegetative growth, yield potential and chem...

Manure characteristics can influence the potential for P transfer in runoff following land application of manures. This research assessed the influence of manure characteristics on P solubility in calcareous soils using manures from poultry (Gallus Domisticus) fed a variety of grain-based diets with the manures containing a range of total P (5.6–16.4 g P kg), water-extractable P (WEP, 0.9–4.7 g...

One important parameter in determining the allowable stress to prevent soil compaction is pre‌compaction stress (σpc). If the stress induced into the soil due to agricultural machinery traffic is lower than the σpc, the possibility of the irreversible (plastic) deformation is low. In this study, plate sinkage test (PST) and confined compression test (CCT) were used to determine the σpc of the d...

Effective manure management to efficiently utilize organic wastes without causing environmental degradation requires a clear understanding of the transformation of P forms from diet to manure. Thus, the objective of this study was to establish quantitative relationships between P forms in diets, feces, and manures collected from U.S. Northeastern and Mid-Atlantic commercial dairy farms. Total P...

a greenhouse experiment was conducted using completely randomised design (factorial) with three replications to study the residual effect of organic manures (municipal solid waste compost and cow manure), zinc (0 and 50 kgha-1) and boron (0 and 10 kg.ha-1) by using znso4 and h3bo3 salts respectively, (applied earlier for millet (panicum italicum l.) crop) on soil properties and chemical composi...

Nitrogen and carbon mineralization rates of 19 manure and compost samples were determined in 1996, with an additional 12 samples evaluated in 1997. These organic amendments were mixed with a soil : sand blend at 2% by dry weight and the amended blends were incubated at constant moisture for 12 (1996) or 24 weeks (1997) at 25 °C. Net N mineralization was measured at 4(1996) or 8-week (1997) inte...

A field experiment was conducted to study the effect of different organic manures and their levels on nutrient status soil microbial activity in rose at Hisar during 2020-21. The treatments comprised 3 types viz., farm yard manures, vermicompost poultry manure 4 control, kg/m2, 5 kg/m2 6 kg/m2. carried out split plot design with three replications. Observation carbon, dehydrogenase alkaline pho...
