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. Key words: Cucumber cultivar, sowing date, marketable yield J. Inst. Agric. Anim. Sci. 26:163-166 (2005)

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.

The experiment was conducted to determine the effect of irrigations and sowing dates on growth and yield performance of wheat in the experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period of November 18, 2012 to March 30, 2013. The experiment was comprised of two factors, viz. factor A: two irrigations namely irrigation (I) and no irrigation i.e. control (I0), and factor B: three sowing dates such as S1: 1st sowing on 18 November, S2: 2nd sowing on 03 December and S3: 3rd sowing on 18 December. The experiment was laid out in a split plot design with three replications. Irrigation was assigned in the main plot, while sowing time was in the sub-plots. Data on grain yield and different yield contributing characters were taken after harvest. Results indicated that the highest grain yield was obtained with I (2.915 t ha-1) and S1 (2.983 t ha-1). The interaction of irrigation (I) and sowing on 18 November (S1) showed the maximum yield (3.387t ha-1), spike length (17.08 cm), 1000 grain weight (43.4 g), spikelets spike-1 (20.03) and grain spike-1 (65.58) of wheat.The Agriculturists 2016; 14(2) 77-85

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.

This experiment was conducted in Homs Agricultural Research Station, Homs, Syria during 2007/2008 and 2008/2009 seasons to study the effect of sowing date and plant density on bolting for four sugar beet varieties, tow are monogerm varieties i.e. Parade and Etna, while the other are multigerm varieties i.e. Nadir and Mammoth. Three sowing dates were applied, began from 15/9 to 15/10, the interval between the sowing dates was 15 days. Three plant densities were executed (133 000, 100 000 and 80 000 plantha-1). Split plot design was used with three replicates. The combined analysis exhibited the significant effect of varieties (V), sowing dates (S), and plant densities (D) on all types of bolting (Early, medium, late and total). Least significant test (L.S.D 0.05) clarified that early autumn sowing (15/9 and 1/10) increased total bolting percent 74.86 and 44.88 % respectively, as compared with date (15/10) 15.57% (control). The plant density (133 000 plant ha-1) decreased total bolting percent 43.56% as compared with the other plant densities (80 000 and 100 000 plant ha-1) 46.35 and 45.40% respectively. The results showed that the monogerm varieties were superior and more resistant to bolting as compared with the multigerm ones.

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.

Context: To analyze the effect of sowing dates and weeding treatments on growth attributes such as total dry matter (TDM), leaf area index (LAI), net assimilation rate (NAR), crop growth rate (CGR), leaf area ratio (LAR) of three rapeseed (Brassica campestris L.) Objectives: The objective of the study was to identify the growth in relation to sowing dates and weed competition and identify the weeding number for better growth of rapeseed. Materials and Methods: This investigation was arranged as factorial experiment based on the split-split plot design with three replications. Four sowing dates were including 18 October (S1), 12 November (S2), 17 November (S3) and 3 December (S4) and three weeding treatments were no weeding (W0), one hand weeding (W1) and two hand weeding (W2) and three varieties viz., BINA Sarisha-5, BINA Sarisha-6 and BARI Sarisha-14 were investigated. Results: The results showed that, TDM, LAI, CGR, NAR and LAR were affected by sowing date and weeding treatments. The highest TDM, LAI and CGR were obtained in the first sowing and two weedings treatment. The highest NAR was found in S2 plants and W0 treatment. The highest LAR was found in S2 plants and W1 treatment. Conclusion: The results obtained in this study suggest that the first sowing and two weeding treatments are superior for the production of rapeseed.

Onions (Allium cepa) in southeastern Georgia are almost exclusively transplanted, with the associated high costs and labor requirements. This study was undertaken to evaluate direct-seeded onions as an alternative production method. This study evaluates variety, sowing date, and fertility on direct seeding short-day onions in southeastern Georgia. Sowing dates, early or mid-October (5 and 15 Oct. 2001 and 7 and 21 Oct. 2002), did not affect total, jumbo (≥3 inches diameter), or medium (≥2 inches and <3 inches diameter) yields. Late October sowing (29 Oct. 2001) did not produce sufficient stand or yield to warrant harvesting. Variety also had no affect on yield of direct-seeded onions. Seedstems (flowering), an undesirable characteristic, was significantly greater with the early October sowing date across all varieties compared with the mid- or late- October sowing dates. Neither variety nor sowing date significantly affected plant stand or plant spacing. Fertilization treatments of 150 or 195 lb/acre nitrogen (N) with various application timings and fertilizer sources did not affect total or medium yields. Jumbo yield was affected in only 1 year with calcium nitrate as the primary N source at 195 lb/acre total N having the highest yield, but did not differ from some treatments at 150 lb/acre N. In addition, fertilization treatments did not affect seedstems, plant stand, or plant spacing. Based on this study, we are recommending that growers should direct seed onions in southeastern Georgia in mid-October, plus or minus 1 week depending on field accessibility. In addition, current fertilizer recommendations for transplanted dry bulb onions should be followed, which includes 150 lb/acre N. This eliminates all of the cost and resources required for transplant production.

A split-split-plot design was used to evaluate the effects of sowing dates and sowing rates on three winter rape cultivars, including ‘PR45D03’, a semi-dwarf hybrid, ‘PR46W31’, a traditional hybrid, and ‘Californium’, an open-pollinated cultivar. August 25 was the optimal sowing date for maximizing protein and oil yields across all three cultivars. Of the cultivars, the traditional hybrid, ‘PR46W31’, produced the highest protein and oil yields on that date. The yields of the semi-dwarf hybrid, ‘PR45D03, were greater than those of the open-pollinated cultivar, ‘Californium’, when these were sown later than the optimal date. Protein and oil yields did not differ significantly among different seeding densities.

A field experiment conducted at Jammu (Jammu and Kashmir) during summer season of 2013 to study the influence of sowing dates and varieties on the yield, heat use efficiency, helio-thermal use efficiency, energy utilization efficiencies and economics of summer mungbean. The experiment was conducted in a split plot design consisting of four sowing dates (20th March, 5th April, 20th April and 5th May) as main-plot treatments and four varieties (SML 668, Samrat, Meha and IPM 02-3) as sub–plot treatments. Higher grain yield (9.33 q ha-1) of summer mungbean was recorded under 20th March sowing date, which was statistically at par with 5th April sowing but significantly higher than 20th April and 5th May sowing. Among the varieties, Samrat produced significantly higher grain yield (7.82 q ha-1) than all other varieties except SML 668. But, the heat use efficiency (HUE), helio-thermal use efficiency (HTUE) and energy pattern was significantly higher at 20th March than other dates of sowing. The varieties Samrat and SML 668 recorded significantly higher HUE, HTUE and energy pattern than IPM 02-3 and Meha. The highest benefit cost ratio (1.42) was recorded with 5th April sowing date closely followed by 20th March (1.39). The variety Samrat also registered the highest benefit cost ratio (1.07) followed by SML-668.
