Field experiments were conducted during Kharif-2017 and 2018 at ICAR-Krishi Vigyan Kendra (KVK), Mangaluru of coastal Karnataka to study the effect of integration of organic and inorganic sources of nitrogen on the yield of midland rice. The results indicated that the integration of organic and inorganic sources of nitrogen significantly influenced the growth and yield attributes of rice. The highest grain yield (5434 and 5372 kg ha-1) and straw yield (6817 and 6927 kg ha-1) were recorded in the treatment comprising VC substituted with 50 percent recommended dose of nitrogen which was on par with PM substituted at 50 percent in both the years. A similar trend was also noticed in both the years for the growth and yield parameters where the highest plant height (94.93 and 96.30 cm) highest productive tillers (16.85 and 18.12) and longer panicle length (17.54 and 18.65 cm) was recorded in the treatment where 50 percent nitrogen was substituted by vermicompost compared to control. The remaining treatments of organic substitution ratios with urea also had a beneficial effect on yield and yield parameters of rice compared to control.

A pot experiment was conducted in Kharif 2009 and 2010 to study the effect of potassium humate and chemical fertilizers on growth and yield attributes of rice (Oryza sativa L). Potassium humate was applied at the rate of 0, 5 and 10 mg/kg soil along with 100 and 75% recommended dose of fertilizers NPK (60, 30, 30 mg/kg) and 12.5 mg/kg zinc sulphate was also applied. Addition of 10 mg/kg PH along with 100% NPK fertilizers and 12.5 mg/kg zinc sulphate caused significant increase in plant height, number of tillers, panicle height, panicle length, test weight, straw yield and yield of rice as compared to 100 and 75% NPK alone.
