Stanje useva i mere nege i zaštite pšenice i ječma u proleće 1998. godine

Abstract

U radu je obrađen prvi deo vegetacionog perioda ozime pšenice i ozimog ječma. Na osnovu stanja useva, količine i distribucije nitratnog azota u zemljištu predlažu se orjentacione mere nege za nastavak vegetacije. Za preciznije preporuke neophodne su detaljnija analiza zemljišta, na nivou parcele. Prihranjivanje, kao jedna od najznačajnijih mera u tehnologiji gajenja pšenice, može biti presudno za formiranje potencijala za prinos zrna. Mere zaštite od štetočina (sitnih glodara) se provode tokom jeseni i zime. Predviđa se pojava bauljara u većoj meri nego ranijih godina. Obzirom na veliku zastupljenost nedeklarisanog semena očekuju se problemi sa zdravstvenim stanjem pšenice i ječma tokom 1998. godine.

Analyzed in the present paper is the first part of the growing season in winter small grains. The paper also states which crop tending and protection measures should be applied. Due to unfavorable weather conditions, the timing of winter small grains sowing was not satisfactory. As a result, the level of plant development at the beginning of this winter is lower than in an average year, and especially so compared with the previous year. It will be possible to remedy this situation if the winter provides conditions for plant activity. In order to for the existing crop potential to be utilized to the maximum, certain crop tending measures will have to be applied. Special attention should be payed to top dressing. According to our observations so far, the control of harmful rodents will be necessary in some areas. Also, attention needs to be payed to the occurrence of Zabrus tenebrioides, especially during repeat sowing.
