Berseem (trifolium alexandrinum l) and Shaftal (t resupinatum l) after various cuts, biomass incorporation at final harvest supplement with nitrogen, impact on the tasseling and silking coincidenceness, days differences from tasseling to silking and grain fill duration of maize

摘要

Two years average results indicated that maximum gap of six days were observed from tasseling to silking. After zero, single and two cuts showed coincidenceness for cob silks and tassel pollen, phenological developments. Maximum grain filling of 43 days were recorded from fallow, shaftal after three cuts and berseem without cut as well. Interactive effect of legumes cutting and N affected grain filling duration. Days gaps between tasselings and silking were lessened for maximum grain fill days. Coincidenceness of inflorescences, tasseling and silking has left beneficial impact on later yield components. The conclusions drawn from the entire research were, as Coincidence and less days differences between tasselling and silking increased grain fill duration, fertilized competent ovules in maize. Organic, unpredicted to be mineralized at need stage and inorganic readily usable form, application both are equally essential under uncertainties for phenological coincidenceness.
