Two field experiments were conducted to know the effect of different doses of nitrogen fertilizer on the growth, botanical parameters and yield of maize and jumbo fodder cultivated with cowpea as inter crop and evaluation of silage. The experimental plots for Jumbo with cowpea and maize with cowpea were applied to nitrogen (N2) levels as urea 0, 100, 150kg ha-1 and 0, 150, 220 kg/ha, respective...

Nitrification inhibitors (Thiourea and nitrification inhibitor “A”) with urea fertilizer were used to enhance the nitrogen efficiency. Nitrification inhibitors and the amount of nitrogen were applied through urea fertilizer to rice seed in Column Lysimeters. The whole experiment was conducted with following treatments such as; urea application as a control at 2gN/10kg (200 kg N/ha), urea applic...

BACKGROUND: Nitrogen is a crucial component of plant nutrition, and its deficiency limits productivity of crops more than any other element. To manage the sorghum crop for achievement of maximum forage production, the farmer should be concerned about nitrogen requirement and plant height. OBJECTIVES: This research was carried out to evaluate response of m...

The objectives of this study were to evaluate the effects of different fertilizer types and application rates on ammonia volatilization loss and to explore nitrogen distribution and nitrogen use efficiency using the 15N isotope tracing technique in different alkaline salt-affected conditions in the Songnen Plain, Northeast China. The results showed a decreasing trend in ammonia volatilization l...

In order to investigate the appropriate combination of chemical and bio-fertilizers and their effectiveness on corn seed yield while defoliating the upper leaves of the ear, a randomized complete block design experiment with four replications. Fertilizer treatments were applied at four levels including 100% urea, 75% urea + 100% Nitroxin, 50% urea + 100% Nitroxin, 25% urea + 100% Nitroxin. In h...

review and goals: the ajowan(carum copticum) is a medicinal plants from apiaceae family that seeds contains 2-4% of volatile oil. 9-17 of chemical composition of ajowan essential oil have been reported(2), it have antibacterial and antioxidant activity of it caused to preserve the food materials(1). the application of chemical fertilizer leads to environmental pollution and ecological disaster ...
