Forty-eight years of rice improvement in Texas since the release of cultivar bluebonnet in 1944
Information on the contribution of plant breeding to changes in yields and other agronomic traits is useful for optimizing selection gains; thus, this study aimed to determine the contribution of Texas rice (Oryza sativa L.) breeding to changes in cultivars released during the 48 yr since the release of ‘Bluebonnet’ in 1944. Twenty-three cultivars were evaluated in three environments and two N ...

Assessing the necessity of surface-applied preplant nitrogen fertilizer in rice systems
California rice (Oryza sativa L.) growers typically use two forms of preplant N fertilizer: aqua NH3 applied 7 to 10 cm below the soil surface (subsurface N) and surface-applied N. The rational for applying about 25% of the total N rate to the surface is to provide a readily available N source for young rice seedlings; however no research has been done to verify this. On-farm field studies were ...

Growth and yield response of rice varieties to foliar application of Boron | JBES 2020 @environmentalxpart
Abstract A field experiment was conducted during the Kharif season of 2018-19 at Rice Research Station Bahawalnagar on the calcareous sandy loam soil to assess the effect of foliar application of boron on growth & yield components of rice varieties (Kissan & Punjab Basmati 2016).The foliar application of boron aqueous solution was used as treatments comprised of control, 0.5kg/ha, ...
