A study was conducted at the Horticulture Farm, Sher-e-Bangla Agricultural University, Bangladesh during April to September, 2012 to determine the suitability of selected plant growth regulators and the proper use and effectiveness of selected organic manures and also their suitable combinations for successful okra production. The experiment consisted of two factors: factor A: growth regulators...

Organic matter and its replenishment has become a major component of soil health management programs. Many of the soil's physical, chemical, and biological properties are a function of organic matter content and quality. Adding organic matter to soil influences diverse and important biological activities. The diversity and number of free-living and plant-parasitic nematodes are altered by rotat...

We assessed the enzymatic activation of four different biochars produced from pyrolyzing swine manure and poultry litter, by co-pyrolyzing these livestock residues with agricultural spent mulch plastic film wastes (plastichars). Enzymatic consisted incubating in soil inoculated earthworms (Lumbricus terrestris), which acted as biological vectors to facilitate retention extracellular enzymes ont...

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...

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...

Porcine production in China represents approximately the 50% of the worldwide pig production. Information about pig husbandry characteristics in China and manure properties from sows to fatteners in intensive pig farms are not broadly available for scientific studies as it is a time consuming, expensive task and highly inaccessible. This study provides a report about solid pig manures (28% dry ...

The key plant nutrients determine the crop’s nutritional status and vigor, while their deficiency impairs growth resulting in absolute failure of crop productivity. Phosphorus is second major essential nutrient for establishment crops. Drastic variations climatic conditions across world low soil fertility, especially phosphorous (P) fixation alkaline calcareous soils arid climate have become se...
