Teosinte (Euchlaena mexicana) is one of the most popular summer growing cereal fodder, yet with comparatively low level of chemical constituents. The quality of this fodder can be improved through better by cultivation management including sowing dates and mixed cropping with legume. The main objective of this study was to determine the forage quality as reflected by major chemical constituents of pure stands of teosinte and binary mixtures of teosinte with commonly available legumes under different dates of sowing. Four fodder combinations; teosinte mono crop, teosinte+ cowpea, tesosinte+ rice bean, and teosinte+ lablab bean was arranged to cultivate in three different date of sowing in the field in a Split Plot Design with 5 replications. Main plot treatments were different sowing dates and sub-plot treatments were combinations of fodder species. Dry herbage mass production, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL) and Ash were determined. The results showed that the significantly the highest Dry herbage and CP were obtained from fodder combination teosinte+ cowpea if sown at 18th April, whereas the significantly highest mean values of ADF and NDF were obtained for teosinte mono fodder crop. However, the lowest average value of ADF and NDF was obtained for fodder combination teosinte with cowpea. The average value of Ash and ADL of both harvest for fodder combination and date of sowing was statistically similar (p>0.05). The effect of treatments interaction/combination on cumulative dry herbage was statistically high (p<0.05) when teosinte+ cowpea was sown at 18th April. However, effect of treatments interaction/combination on average value of CP, NDF, ADF, ADL and Ash of both harvests (g/kg DM) was statistically similar (p>0.05). The results showed that mixture of teosinte with cowpea sown at 18th April could be the best combination in terms of quantity as well as for major chemical constituents that could reflect better quality of fodder harvest.

Results of a two-year investigation (2005 and 2006) for the yield and quality of fenugreek seed (Trigonella foenum graecum L) obtained on the location in South Banat (around Pancevo) on marsh dark soil are presented in the paper. Fenugreek seed used in this investigation was produced in the collection of the Institute of Medicinal Plant Research "Dr Josif Pancic" in Pancevo. The effect of sowing date on yield (kg/ha) and quality of fenugreek seed (germination energy and total germination) were investigated. Sowing was carried out on seven dates, 10 days between dates of each sowing. Yield of fenugreek seed sowed on different dates differed in both years. Sowing carried out in the first two weeks in April resulted in considerably higher yield compared to sowing at the end of April and during May. The highest yield was produced in the second sowing date from April 10, then in the first (April 1) and the third sowing period (April 20). The lowest yield of fenugreek seed was recorded in sowing carried out at the end of May. Yield of fenugreek seed wasn't significantly different in study years. Earlier dates of sowing resulted in seed of better quality (better germination energy and total germination). In the second sowing date fenugreek seed obtained was of best germination energy and total germination (approx. 99%). Later sowing dates gave seed of lower quality. So, sowing carried out at the end of May resulted in seed with the lowest value of germination energy and total germination (approx. 91%).

An experiment was carried at Multi Location Testing site Barguna to determine suitable variety of mustard (Brassica species) for the late sowing condition for the coastal area of Bangladesh during rabi season of 1998-1999 and 1999-2000. Four varieties of mustard such as Daulat, Rai-5, Improved tory-7, and Ishurdi local with four sowing dates viz.15 Nov, 23 Nov, 30 Nov. and 7 Dec. were used for the experiment. The experiment was laid out in a split plot design with sowing date in the main plot and varieties in the sub plot. The results revealed that the variety Daulat (1035 kg/ha) and Ishurdi local (1014 kg/ha) produced identically superior yield irrespective of sowing time. 15 November (1164 kg/ha) and 23 November (1002 kg/ha) recorded identically superior yield irrespect of variety. Daulat and Ishurdi local variety sowing could be delayed up to 30 November to obtain a profitable yield of (872 kg/ha) and (940 kg/ha) respectively which was still economically profitable.

Lipid Lowering Effect

Nonalcoholic fatty liver disease (NAFLD) is a prevalent chronic liver disease. The Hugan Qingzhi formula (HGQZ) has been proven effective in treating NAFLD through clinical and pharmacological mechanism studies. A screening study of the chemical components was carried out to better control the quality of this formula. Current research has combined biological activity assessment with chemical analysis to screen and identify the bioactive compounds in HGQZ for use as potential quality markers (Q-markers) to control the quality of this herbal product. The HGQZ extracted by three different solvents was evaluated in a free fatty acid-induced hepatic steatosis LO2 cell model. Simultaneously, the twelve major chemical constituents of these extracts were quantitatively measured by ultrahigh-performance liquid chromatography coupled with triple quadrupole mass spectrometry (UHPLC-QQQ-MS/MS). Extraction with 50% ethanol showed the most potent lipid-lowering effect in steatosis LO2 cells and the highest extraction rate of major chemical constituents. Correlation analysis was used to establish the relationship between the biological activities and chemical characteristics of these extracts. The results showed that the contents of typhaneoside, hyperoside, isoquercitrin, isorhamnetin-3-O-neohesperidoside, notoginsenoside R1, and alisol B 23-acetate were positively correlated to the lipid-lowering effect. The subsequent bioassay confirmed that typhaneoside, isoquercitrin, and alisol B 23-acetate played the role of reducing the lipid effect. In conclusion, 50% of ethanol extraction produced the most active extract of HGQZ. Typhaneoside, isoquercitrin, and alisol B 23-acetate could be considered potential Q-markers for the quality control of HGQZ.

SUMMARYTwo varieties of okra were sown at approximately 14-day intervals from 1 April to 1 June for 2 years during the main rainy season in Nigeria. Low soil temperature and moisture, which resulted from a combined effect of high solar radiation, high atmospheric temperature and low rainfall, led to poor seedling emergence at the early sowing dates.The growth of the fewer plants of the early sowing dates were more vigorous than those of later sowing dates and they attained 50% flowering earlier and had a longer harvest duration. This resulted in increases in number of pods per plant, pod length, pod diameter, pod volume, pod weight and pod yield per ha, indicating compensatory growth by the fewer plants in the early plantings. The relatively lower values obtained for these variables with the late sowing dates were also attributed to possible poor soil aeration arising from the increased rainfall during their growth period.Sowing dates did not generally affect the percentage moisture, oil and protein in the pods. The effects of varieties on the variables measured were more uniform than those of sowing dates and mostly not significant.

Pea (Pisum sativum L.) are grown for canning and freezing on over 40 000 ha (1979–1982 average) in Wisconsin and substantial acreages are also seeded to other canning crops. The majority of this land remains idle after harvest in late June or early July. Crops could be seeded on this land to be used as forage for livestock or for energy conversion. The objective of this study was to evaluate the yield and forage quality of several summer annual crops seeded after pea harvest. Field experiments were conducted during 1980 and 1981 on a Piano silt loam soil (Typic Argiudoll) at Arlington, Wisconsin. ’Alaska’ pea were planted in late April and harvested in late June. After pea harvest, plots were cultivated to prepare a seedbed for the second crops, which were planted in late June. The second crops included three sorghum (Sorghum bicolor (L.) Moench) cultivars, soybean (Glycine max L.), normal and male-sterile early maturity (RM 95) corn (Zea mays L.), and two mixed cropping systems. Mixed crops were male-sterile corn grown with either soybean or field bean (Phaseolus vulgaris L.). Second crops were harvested late in September. Male-sterile corn had the highest 2-yr average yield of DM at 9.8 Mg∙ha−1 and sweet sorghum had the second highest yield even though it was reseeded 13 days later in 1981 due to poor germination. The normal corn average yield was only 0.5 Mg∙ha−1 less than that of sweet sorghum and should be considered a viable option as a second crop after canning pea harvest. Soybean would not be recommended for this use because its yield was considerably below that of any other crop in both years. Soybean forage was highest in N and lowest in NDF. Of the grass crops the highest IVDMD values were for normal corn (64.2%), male-sterile corn (63.7%), and sweet sorghum (64.9%). Sorghum-sudangrass was lowest in IVDMD in 1980 (53.0%) and in 1981 (60.1%). Sweet sorghum and the two corn types were lower in neutral detergent fiber, acid detergent fiber and acid detergent lignin than sorghum-sudangrass. Considering both yield of DM and the quality of the forage produced, male-sterile corn, sweet sorghum and normal corn can be identified as the superior crops for planting after pea harvest. Mixed cropping male-sterile corn with soybean or field bean gave no advantage in yield or quality.Key words: Corn, sorghum, pea, IVDMD, NDF, N

Variations in the sowing date of chia (Salvia hispanica L.) reflect directly on the physiological potential of the produced seeds. This study aimed to analyze the yield and the physical and physiological quality of seeds from the main stem and branches of Salvia hispanica plants grown at different sowing dates. A field experiment was conducted in the crop year of 2016/2017 in five sowing dates (16/09/22, 16/10/28, 17/01/03, 17/02/08 and 17/03/24) in a randomized complete block design with four replicates. Harvest at each sowing date was done when 80% of the leaves of each plant exhibited a darker color, indicating that they were dry. Seed yield was determined in each plant compartment (main stem and branches) and final ear length (cm) and diameter (cm) were also measured at all sowing dates. The following physical and physiological tests were performed to determine seed quality: water content, mass of one thousand seeds, germination test, first count germination, length (root and hypocotyl) and dry matter of the seedlings. Chia can be sown from September to February providing seed yield with high physical and physiological quality. The physical and physiological quality of the chia seeds does not differ between main stem and branches. In late sowing, there is the risk of frost occurrence what may impair the physiological quality and the yield of chia seeds. The best sowing month for obtaining higher yield of chia seeds in a south subtropical region is January.

Eleven Brazilian hexaploid triticale cultivars (2n = 6x = 42), from three breeding programs, were evaluated for their ability of self-fertilization in 2006 and for meiotic behavior, meiotic index and pollen viability at two sowing dates in 2007. High potential of self-fertilization was observed, with values up to 89.52 %. Many irregularities were found in the meiotic analysis, such as the presence of univalents, laggard chromosomes and micronuclei in tetrads, which compromised both meiotic behavior and meiotic index. At the first sowing date, more suitable for normal plant development, overall mean values of 52.68 % for normal cells and 64.95 % for meiotic index were observed. At the second sowing date, less appropriate for the crop, overall means of 52.23 % for normal cells and 58.24 % for meiotic index were obtained. Despite all the irregularities, considerable pollen viability was observed, reaching overall means of 92.08 % and 91.07 % for the first and second sowing dates, respectively.

An experiment was conducted in split plot design with three replications to determine the optimum date of sowing for commercial cultivation of cucumber at Lamjung Campus, Sundarbazar (750 m asl), Lamjung during December 1999 to November 2000. The cvs. Green Long and Bhaktapur Local were used in the main plot and the sowing dates in the sub-plot. Sowings were done on the 15th of the months December 1999 and February, April, June and August 2000 at an interval of two months. Manure and fertilizers were applied @ 20 t farm yard manure and 120:60:50 NPK kg/ha in all the sowings. Yield attributing characters such as plant stand, vine growth, first male and first female flowers bearing nodes, number of female flowers per plot, sex ratio and number of harvests were insignificantly different in December and February sowings. However, the periods of phenophases such as sowing to the first male and first female flowers and sowing to first harvest and last harvest were significantly longer at December sowing followed by those at February sowing. The three latter sowings showed poor performance in respect to those characters. February sowing produced significantly the highest number of marketable fruits (79.16 thousand/ha) and marketable yield (53.97 t/ha) than the earlier December and three latter sowings. The December sowing also produced significantly higher marketable yield (23.76 t/ha) than June and August sowings. Hence, the cvs. Green Long and Bhaktapur Local could not produce economic yields at April, June and August sowings at Sundarbazar (middle hill) Lamjung.

In order to study the effect of planting date and cultivar on seed yield and germinating ability of soybean, an experiment was conducted for two seasons (2014 – 15 and 2015 – 16 ) at Regional Agricultural Research Station, Nandyal, Andhra Pradesh. Two popular varieties, viz., JS-335 and JS-93-05 were sown on four sowing dates i.e. July 2nd fortnight (FN), August 1st FN, August 2nd FN and September 1st FN during the two consecutive kharif crop seasons in FRBD design, replicated thrice. The variety JS-335 recorded significantly higher yield (1296 kg ha-1) than JS-93-05 (690 kg ha-1) . Early sowings during July 2nd FN and August Ist FN recorded significantly at par yields (1087 kg ha-1, 1101 kg ha-1 respectively) with good initial and aging germination percentage (81%, 58.8% respectively). Though September 1st FN sown crop recorded significantly lowest seed yield (860 kg ha-1), the initial and aging germination percentage were highest (88.6%, 66.0%).

An experiment was carried out at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during three consecutive seasons in 2004-2006 to find out the effect of sowing date on physiological quality of soybean seed. The experiments included six sowing dates viz. 4 Nov, 24 Nov, 14 Dec, 3 Jan, 23 Jan and 12 Feb and two cultivars namely G-2 and PB-1 in Rabi 2004-05; four sowing dates viz. 25 Jul, 14 Aug, 3 Sept and 23 Sept and three cultivars namely G-2, PB-1 and BS-5 in Kharif II 2005; four sowing dates viz. 26 Nov, 16 Dec, 5 Jan, and 25 Jan, and two cultivars viz. G-2 and PB-1 in Rabi 2005-06. The experiments were conducted in split-plot design with three replications. Results revealed that cultivar G-2 had higher germination and vigour than cultivar PB-1 or BS-5 in all the three seasons. November and December sowing produced seeds with higher germination and vigour for all the cultivars in Rabi season. On the other hand, September sowing produced seeds with high germination and vigour during Kharif II. The study indicated that soybean seeds with high germination and vigour could be obtained by sowing during November to December in Rabi season and August to September in Kharif-II season.
