The effects of tillage and residue input amounts on soil phosphatase (alkaline phosphomonoesterase ALP, acid phosphomonoesterase ACP, phosphodiesterase PD, and inorganic pyrophosphatase IPP) activities and soil phosphorus (P) forms (total P, organic P, and available P) were evaluated using soils collected from a three-year experiment. The results showed that no-till increased soil total and org...

A field experiment was conducted during Kharif 2019 at the Experimental Farm of Department Agronomy CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur (H.P.) to investigate effect different tillage systems and varieties on yield rice. The treatments consist three rice (HPR 1156, HPR 2656 2795) which were tested under viz., conventional tillage, minimum without residue with retention. set up ...

Smallholder farmers in southern Africa have reported on increased labour requirements for hoe weeding due to high weed infestations in conservation farming (CF) fields. However, CF proponents claim that weed pressure and labour requirements for weeding decrease within the first three years under the recommended CF practices. An observational study was carried out during the 2008/09 cropping sea...

The use of continuous no-tillage cropping raises concern about water and nutrient movement into subsoil due to high soil bulk density. Deep ripping (i.e., paraplowing) might be a conservation strategy to loosen surface and subsoil without excessive incorporation of surface crop residues. We initiated a multi-year study comprised of four water catchments (3.1-6.7 acres each) that had previously ...

since wheat-rice cropping system is down in about 50000 hectare of khoozestan province and also necessity of optimum land and water utilization, this study was condulted during one year (2008-2009) in shawoor agricultural research station to compare different conservation tillage system with traditional system for wheat cultivation in paddy residue. experiment conducted in randomized complete b...
