This study aims to describe the morphological character and seed growth potential of biduri (Calotropis gigantea) accession growing in tourist area South Central Lombok (Kuta Mandalika, Tanjung Aan, Seger), was carried out during February-August 2020. The method used descriptive observative with survey techniques sampling by purposive based on population biduri. experiment a completely randomiz...

The study was conducted during 2013/14 main cropping season in Ebinat district with the aim of studying effects seeding rates and row sowing methods on growth, yield components tef. Planting material improved tef variety ‘Quencho’ (DZ-01-387) used as a test crop for experiments. Two factors 3 (5, 7.5 & 10 kg/ha) inter-row spacing (15cm, 20cm 25cm) were combined to form 9 treatment. treatments l...

Sewage sludge at the rate of 0, 40, 80, 120 and 240 t/ha showed that the number of filled grains per panicle, dry weight of grains and weight of 1000 grains of rice (Oryza sativa L.) were the significantly highest where 240 tons of sewage sludge per hectare was added. The contents of N, P, K, Ca, Mg, Fe, Cu, Zn and Pb in rice grains increased significantly with increasing rate of sewage sludge ...

The erect panicle model super-rice can rationally transform the solar energy into accumulated organic matter (biomass) and increase grain yield. The phenotype of erect panicle architecture controlled by DENSE AND ERECT PANICLE 1 (DEP1) has been used in rice breeding for nearly a century owing to its high-yield, lodging tolerance with strong stem, reasonable population structure and high nitroge...

Rice (Oryza sativa L.) breeding seeking to combine high productivity and cold tolerance for the temperate Latin America region is an important challenge. We estimated some useful parameters which can be used to investigate the genetic control of agronomic characters in crosses combining cold tolerance and productivity. A partial diallel design was used in crosses between six tropical indica ric...

QTL underlying related traits at the late developmental stage under two different nitrogen levels were investigated in rice using a population of chromosome segment substitution lines (CSSL) derived from a cross between Teqing and Lemont. A total of 31 QTLs referring 5 traits, that is, plant height (PH), panicle number per plant (PN), chlorophyll content (CC), shoot dry weight (SDW) and grain y...
