Introduction Interest in organic production methods for vegetables continues to increase. Production practices for organic field production of vegetables have a long history, but practices to grow organic vegetable transplants in a spring greenhouse are poorly known. Organic fertilizers and composts are available but the efficacy and rates for use have not been evaluated. Experiments in the sum...

The present investigation deals with the role of Plant Growth Promoting Rhizobacteria and chemical fertilizers alone or in combination on urease, invertase and phosphatase activities of rhizospheric soil and also on general impact on growth of safflower cvv. Thori and Saif-32. The PGPR (Azospirillum brasilense and Azotobacter vinelandii) were applied at 10cells/mL as seed inoculation prior to s...

Nitrogen fertilizers play an important role in the cultivation of crops, excessive and improper usage cause severe issues with respect to human environment. It is essential go for alternative sources nitrogen like nano slow controlled release nitrogen.An experiment was conducted at Agriculture Research Farm, Lovely Professional University, Phagwara, during kharif 2022 by using source maize crop...

A field experiment was conducted to assess the effect of farmyard (cattle) manure (FYM) and inorganic nitrogen (N) phosphorus (P) fertilizers on growth and tuber yield of potato (Solanum tuberosum L.). The treatments consisted of factorial combination of 4 levels of FYM (0. 10, 20 and 30 t h-1) and three levels of inorganic NP fertilizers (0, 33.3%, 66.6% recommended rates) laid out in a Random...

Field experiment was conducted at International Crops Research Institute for the Semi-Arid Tropics, Hyderabad during early summer season in 2021 and 2022 to study “Effect of integrated use Nano Non–Nano fertilizers on growth yield sunflower under semi-arid conditions”. The carried out using randomized block design with 3 replications comprised 12 treatments. averages all indicators were compare...

This Bulletin discusses several manufacturing processes for organic compound fertilizers overseas and in Taiwan. The different formulations of N-P2O5-K2O in the fertilizers are also reported. The yield response of different crops from the application of organic compound fertilizer reflects their superiority over organic fertilizers. Experiments also showed that the use of organic compound ferti...

ome organic fertilizers are suitable for greenhouse crops and can also fit the current ways of applying fertilizers commercially. However, not much information is available on plant response, nutrient supplying power, or the environmental impact of nutrient leaching with organic fertilizers. Not surprisingly, because of their differences in the makeup, levels of success in growing acceptable gr...
