Reducing chemical fertilizers is critical for maintaining soil health and minimizing environmental damage. Biochar-based organic reduce fertilizer inputs, improve fertility, increase crop productivity, risks. In this study, a pot experiment was conducted in greenhouse to assess the potential of biochar-based inorganic fertility Okra yield. Seven treatments with three replicates were arranged co...

Greenhouse experiments were carried out for phytoremediation of the Pb/Zn abandoned tailings (pH 3.2 and high metal content) of Rampura-Agucha Mines, Rajasthan. Vigna unguiculata (L.) Walp. (cowpea) was chosen as a test crop. On unamended tailings, the seeds of the test plant showed no germination. The tailing was amended with lime (3% on weight basis), 3% lime + NPK (diammonium phosphate at 60...

We studied the suitability of municipal solid waste compost (MSWC) application to submerged rice paddies in the perspective of metal pollution hazards associated with such materials. Experiments were conducted during the wet seasons of 1997, 1998 and 1999 on rice grown under submerged condition, at the Agriculture Experimental Farm, Calcutta University at Baruipur, West Bengal, India. The treat...

Wheat (Triticum aestivum L.) was grown in earthen pots containing soil of Balkasar Soil Series (Sandy Loam) in green house at the Department of Soil Science and SWC, Pir Mehr Ali Shah Arid Agriculture University, Rawalpindi during Rabi season, 2007. The Crop was treated with two levels of Phosphorus (40 and 80 kg P ha-1 ) in the form of SSP, TSP, NP and DAP. A basal doze of 100 kg N and 60 kg K...

The objective of this study was to evaluate the effect an early application potassium (K) fertilizer on pearl millet (Pennisetum glaucum L.) grown during fall/winter performance maize (Zea mays silage in succession. Using a randomized block design, harvest, plots were composed and six doses K (0, 30, 60, 90, 120 150 kg K2O ha-1) as muriate potash (57% K2O) addition fallow. In summer cultivation...

The experiment was conducted at lowland series of wet lands, International Rice Research Institute (IRRI) Farm, Los Banos, Laguna, Philippines. The rice variety PSBRc 82 was raised during wet season (June – October), and the experiment was laid out in randomized block design with four replications. There were eleven treatments viz., control, recommended NPK fertilizer, -N, -P, -K, LCC 3, LCC 4,...
