Black gram (Vigna mungo L) is a short duration crop belongs to leguminacae family. Black gram is rich in protein (25-26%) and grown as intercrop, catch crop also as solo crop. It is also called as urd bean. In India the area under black gram cultivation is 3.30 million ha producing 1.60 million tonnes, with the mean productivity of 0.49 kg ha -1 and contributes 11% of total production in the co...

Phosphate tailings pose significant risk to the environment as point sources of basic, carbonate-rich effluents. This waste may be judiciously used for the biofertilizer preparation. The enrichment of compost by adding low grade rock phosphate also offers a potential preposition for the effective utilization of insoluble P. Experimentally, the compostable material (Biogas spent slurry) is mixed...

objective: this field experiment was laid out in order to study on effect of nano and bio fertilizers on yield and yield components of tomato (lycopersicone sculentum l.) during the growing seasons 2013- 2014. methods: the experiment was laid out in a factorial based on randomized block design with three replications. treatments were k nanofertilizer in five levels such as (0, 100, 200, 300 and...

this study was conducted to investigate the effect of organic and bio-fertilizers on trifluralin durability.herbicide persistence is an important consideration in crop production since residue levels of trifluralin herbicides can persist to the next growing season and may injure sensitive crops in the rotation. residues of trifluralin persist in the soil for long periods. extremely small amount...
