گزارش نهایی و نتایج طرح بررسی و مقایسه عملکرد و میزان پروتیین ارقام و هیبریدهای جدید سورگوم علوفه ای

Experiments carried out on several indigenous and im ported sorghum hybrids from 1986- 1988, has led to the selection of the new imported hybrids and omission of others. Therefore these findings brought up the necessity for the current study in 1981- 91. Two promissing cullivars namely, F-1104 as check and Beef builder as high yielding cultivars from the previous experiment and six other new hybrids were selected for the current experiment. Among cultivars, sugar - graze,super-dan and Jumbo with 228.8, 220 and 210.8 T/ha respectiVely have produced the highest forage yields. Sugar - graze, Super-dan and Beef - builder. with 42.9, 42.7 and 40.1 T/ha. dry matter respectively were the highest producers amongst the 8 cultivars. From the point of the protein content aLL the Cultivars except (N.K 725 ), were superior to the Check (F -1104) Beef builder, Sugar - graze and Jumbo Cultivars , have significantly produced more prosik acid compared to the check. Where as Super - dan with the lowest acid content perfor med better than all other cultivars.
