Rice (Oryza sativa L.) is first staple crop of Nepal. The national average yield of rice is less than its potential yield, for which poor agronomic management has been reported as the critical factor. Among various agro-management practices seedling age, seeding density and nitrogen rates significantly affect the growth and yield of rice. The lower seeding density produces the taller plant, more effective tiller, lower sterility and higher grain yield. On the other hand, seedling of older age from higher seeding density gives the lowest yield. Transplanting younger seedling with low seeding density and application of recommended dose of nitrogen gives a higher yield. This article summarizes various effects of seedling age, seeding density and nitrogen rates on plant height, number of effective tillers, number of filled grains, thousand grain weight and grain yield of rice. This information may be useful for maize growers and researchers.

Biological Inoculants

A field experiment was conducted at Tamil Nadu Agricultural University from July 2001 to July 2002 to study the effect of different stubble management practices using biological inoculants on the growth and yield of rice in rice-based cropping systems. inoculation with Trichoderma viride during stubble incorporation followed by the application of 120 kg N ha-1 in 4 splits produced significantly taller plants, higher LAI and dry matter, a larger number of productive tillers, longer panicles with more filled grains and higher grain yield. However, it was on par with the stubble management practice involving Trichoderma viride followed by the application of 90 kg N ha-1 in 4 splits.

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.
