Background: The microspores of five tropical japonica and indica rice genotypes were subjected to androgenic studies. effect growth regulators on callus induction studied improve the anther culture efficiency. Methods: cold pre-treatment panicles at 10°C done different days intervals viz., 5, 8, 10 12 days. uninucleate stage selected dusted after pre-treatment. anthers cultured in N6 basal medi...

A field experiment was conducted during Kharif 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University Agriculture, Technology And Sciences, Prayagraj (U.P) to determine the “Influence Phosphorus and Micronutrients on growth yield Rice (Oryza sativa L.)”. The laid out in Randomized Block Design comprising 10 treatments which include three levels viz @ 50,60 70 kg/ha. mic...

The study aimed to evaluate the yield components and physiological quality of rice seeds produced, obtained from coated with rusk ash kaolin®. Treatments consisted coating two sources silicon (silicate aluminum-70% SiO2 (kaolin® husk ash- 95% SiO2) at doses 0; 30; 60; 90 120 g.100 kg-1 seed. Yield were evaluated: Seed per plant, number panicles plant plant. subjected germination, first ...

A field experiment was conducted on “Effect of foliar spray Nano urea yield and economics rice (Oryza sativa L.) at Bihar Agricultural College Farm, Sabour during kharif season 2022 in randomized block design (RBD) with six treatments four replications. The results showed that highest number tillers meter-2, panicles filled grains panicle- 1, 1000-grain weight (g), grain (4899 kg ha-1) straw 60...

Rice is the primary source of energy for international population. In any crop breeding programme, presence genetic variability vital broadening gene pool. An excessive magnitude in population required selecting a genotype with excessively applicable traits. The heritability estimates along amount provide us an idea gain due to choose. Specific direct developments (number panicles/plants, fille...
