Abstract

O‘simlikning serpoya bo‘lishida tuplanishning ahamiyati katta, lekin o‘simlikning me’yoriy qalinlikda bo‘lishida tuplanish yordamchi omil hisoblanadi. Agar ekish me’yori kam bo‘lganligi natijasida maysalar siyrak chiqsa, ular ular qanchalik sertup bo‘lmasin baribir ko‘zlangan hosilni qoplay olmaydi. O‘zbekiston sharoitida gektariga 5-7,5 mln dona sholi ekilganda ya’ni, har m2 yerda o‘rimga qadar 250-350 tup atrofida o‘simlik va 450-500 ta ruvakli poya bo‘lgan taqdirda sholidan mo‘l hosil olingan. O‘rganilayotgan istiqbolli kechpishar Mustaqillik navida nazorat navi (UzROS 7/13) va ekish muddatiga (25 aprel) nisbatan 5 mayda gektariga 4 mln. dona me’yorida ekilganda haqiqiy tuplanish 2,9 foizni tashkil qilib, gektaridagi o‘simliklarning qalinligini 4.47 mln. donaga oshirish imkoniyatini berilishi aniqlandi.
