Sorghum Bicolor L

The production of sorghum hybrids depends almost entirely on one genic-cytoplasmic sterility system (Milo-Kafir, A1 Cytoplasm), therefore its importance in increasing the diversity of the number of male-sterile sources, as the named A2 Cytoplasm. This system was introduced at the Rio Bravo Experiment Station (lNIFAP-CIRNE) in Tamaulipas, Mexico, where ge-netic material and seed production were developed. The objetive was to compare the seed quality ofthe isocytoplasmic genotypes (A1 and A2 cytoplasm). A Completely Radomized Experimental Design with Factorial Arrangement and two replications was used. The results show that there were no differences between the two types of cytoplasm (A1 and A2) for the following quality traits: volumetric weight of seeds, 1000 seeds' weight, germination(G) and seedling dry weight (SDW), through nine months of storage; whereas in vigor (G and SDW after fast aging) the A2 cytoplasm surpassed the Al cytoplasm and the same behavior was observed on the seed harvested at its physiological maturity, while at harvest maturity the Al was superior in G and SDW.

AbstractThe field emergence ability of a total of 88 seed lots of spring barley (Hordeum vulgare L.) harvested serially during development in 2 years was compared, as was the size of the resultant seedlings. For seedsproduced in each year, field emergence and the mean dry weight of emerged seedlings were significantly greater for seed lots harvested some timeafter physiological maturity (end of the seed-filling period) than for those harvested at or before this developmental stage. This is compatiblewith results for the potential longevity of these lots. It is concluded that barley seed quality continues to increase after physiological maturity, and that the developing seeds attain maximum quality (however this is assessed) close to when the seed crop can be combine harvested. Positive correlations were detected between seedling emergence and seed dry weight (P<0.05) and between the mean dry weight of emerged seedlings and seed dry weight (P<0.005) among seed lots harvested close to when maximum quality was attained in four seed production environments.

The aim of this experiment was to determine the effect of the addition of ash and sand-compost proportion in the media on the growth of sorghum (Sorghum bicolor L.). Theexperiment was conducted on December 2015 to January 2016 in the Botanical Laboratory,Biology Department, Faculty of Mathematic and Natural Science, Lampung University, andwas conducted in a complete randomized design by using two treatments. The first treatmentwas the addition of ash in two equivalents (with and without ash), the second treatment wasthe addition of sand-compost proportion in four equivalents (2 kg of sand, 1¾ kg of sand +¼ kg of compost, 1½ kg of sand + ½ kg of compost, 1¼ kg of sand + ¾ kg of compost). Theobserved variables of the growth were the number of the roots, the crown’s length, the wetweight, and the dry weight. The number of the roots was determined by observing thenumber of the roots present at the base of the stalk of each plants. The length of the crown(cm) was determined by measuring it from the stalk’s base to the edge of the longest leaf.The wet weight (g) was determined by measuring the whole part of the plant using ananalytical balance. The dry weight (g) was measured after the plants were stored in an ovenfor three hours in the temperature of 70o-80oC. The result showed that the best growth wasobtained from the media with the sand equivalent of 1¼ kg of sand added with ¾ kg ofcompost without ash.Key words: Ash, compost, growth of sorghum (Sorghum bicolor L.), sand

A pot experiment was conducted to determine the effects of varying Cr (VI) levels [0.0–4.0 mg Cr (VI) kg-1 soil in the form of potassium dichromate] on the some quality parameters of sorghum Sorghum bicolor (L.). Quality parameters was measured in terms of protein content, chlorophyll content, and IVDMD ( In vitro dry matter digestibility) content at different growth stages, i.e. 35 DAS, 70 DAS and 90 DAS (Days after sowing) that were adversely affected with an increase in Cr (VI) levels from 0.0 to 4.0 mg Cr (VI) kg-1 soil. The decline in protein content 4.67 g/ kg dry weight at T4 was observed as compared to control (T1) ( 8.96 g/kg dry weight basis) at 35 DAS in leaves , Total chlorophyll content declined from 3.25 mg g-1 fresh weight (T1) to 2.40 mg g-1 fresh weight (T4) at 35 DAS and IVDMD content declined from 43.60 to 33.60 per cent dry weight basis with increment in chromium concentration. It is concluded that Cr (VI) at higher doses (4.0 mg Cr (VI) kg-1 soil) adversly affects the quality parameters of Forage sorghum Sorghum bicolor (L.) however, quality parameters are responsible for nutritive value of sorghum Sorghum bicolor (L.).
