Bir ekinli dehqonchilik

Bir ekinli dehqonchilik, yakka ziroatchilik (monokultura) — bir xil ekinni bir joyda uzok, muddat uzluksiz oʻstirish. Bu usul tuproqning fizik va kimyoviy xossalarini yomonlashtiradi, yerda ozuqa moddalarni kamaytiradi, tuproq unumdorligini pasaytiradi. Shuningdek, oʻstirilayotgan ekinga moslashgan hasharot va kasallik kupayadi, dalani begona ut bosadi. Maye, bir dalada gʻoʻza qaytaqayta oʻstirilganda vilt kasalligi koʻpayib, hosildorlik pasayadi. Yerdan oqilona foydalanish uchun bir ekinni uzok, muddat bir dalaga ekilishiga yoʻl qoʻymaslik, dalaga ekinlarni navbatlab turish uchun almashlab ekish joriy qilinadi.
