Due to phosphorus being unavailable to all but a small portion of plants, agricultural productivity diminishes. Phosphorus-deficient soils have traditionally been fertilized in order to decrease the severity of the environmental impact. Improving agricultural management practices for sustainable crop output, including reduction in phosphorus loss in terms of runoff, is the emphasis of this study. Investigating chemical fractionation mechanisms to distinguish between occluded P, acid-extractable calcium-bonded P, and non-occluded P is necessary for increasing inorganic phosphorous (Pi) in mung bean (Vigna radiata) types and establishing net grazing systems. Phosphate (P) is known to be transferred between pools due to weathering, with the highest P retention rates found in clay-rich soils. Soil with a finer texture is better able to absorb and fix phosphorus, which means more nutrients and water can be ma...

So, post-harvest management is the important part of floriculture sector. Pre-harvest, Post-harvest and Harvesting (Stage of harvesting, Time of harvesting, Method of harvesting) is strongly related to self-life of flowers and ornamentals. Flowers and ornamentals should be harvested at a proper time, otherwise loss of quality and self life. Some example is Rose (Tight bud stage), Marigold (Fully opening Stage), Orchid (3 to 4 days after full opening of flower), lilium (Bud colour show red) and others. Major advantage of post-harvest management is throughout the year flower supply, Farmer can get more profit, Crops spoilage is very low and more employers also involve under post-harvest industry but, some physiological disorder also found during post-harvest condition such as; calyx splitting of carnation, Bent neck of rose, Bud...

The field experiment was carried out in Randomized block design, having eleven (11) treatments with three replications. Finally, it may be concluded that highest weed control efficiency was recorded under hand weeding twice (T7) followed by pre-emergence application of Pendimethalin along with one hand weeding...

The field experiment was laid out in Randomized Block design with three replications. The treatment receiving organic sources of nitrogen significantly influenced the height of plant, leaf area index, dry matter accumulation, crop growth rate, T14 was found to be superior to other treatments and the yield components of grain amaranth were significantly differs with the combine sources organics than the sole application of organics over control treatment. The highest pooled seed yield of 16.9 q.ha was recorded under T14 treatment followed by 14.6 q.ha at T12 and T8 respectively. The maximum higher net return accrued to T8 and followed by accrued to T10 during both the year...
