Background: Indian mustard (Brassica juncea L.) is a prominent seed crop grown in most of the northern part of India. It is also grown in different cropping systems where sowing time differs as per availability of vacant field prior to preceding crop. Being a rabi season (winter) crop its physiological as well as morphological developments are markedly influenced by temperature condition.Methods: An investigation was carried out during rabi season of 2010-11 and 2011-2012 at oilseeds research farm Kanpur (UP) with 4 sowing dates (30th Sept. 11th 21st, 31st Oct.) and 5 genotypes (Kranti, Maya, PAC-437, PBR-357, Rohini) of mustard on sandy loam soil under irrigated condition to study different physiological and yield attributing characters.Result: The results shown that among the sowing dates, 11th October registered the highest values of specific leaf weight (SLW), Crop Growth rate (CGR) estimated at 60-90 DAS, seed yield and oil content. The early sowing at 30th Sept. registered significantly lowest seed yield (1880 Kgha-1) and seed oil content (38%). In case of genotypes, PAC-437 registered highest values of SLW (29.60 mgcm-2), NAR (113.3 mg dm-2 day-1), RGR (26.7 mg g-1 day-1), CGR (0.94g plant-1 day) at 60-90 DAS, seed yield (2079 kg ha-1). The interaction effect of sowing date × genotypes was found significant in most of the cases. Thus, the results concluded in Indian condition specially the northern part, 11th October proved to be the optimum sowing time of mustard. As far as the genotype is concerned, Kranti perform well of this date of sowing while PAC-437 proved its superiority over other genotypes as well as different sowings date of October month.

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.

A field experiment was conducted at the research field of Agronomy Division, BARI, Joydebpur, Gazipur during rabi season of 2015-16 to evaluate the flowering behavior and seed yield of French bean. Three varieties viz., BARI Jharsheem-1, BARI Jharsheem-2 and BARI Jharsheem-3 were sown at 15 November, 30 November, 15 December and 30 December for getting temperature variation. Sowing dates based temperature variation, significantly affect the flowering behaviour and seed yield of French bean varieties. Flowering duration of 15 November and 30 November sowings were longer due to prevailing low temperatures (Min.11.72-13.240C and Max. 25.02-25.820C). On the contrary, minimum flowering duration was recorded in 30 December sown crop (11-17 days). Minimum duration might be due to prevailing high temperature (Min. 16.05-18.610C and Max. 28.89-31.310C) that shorten the flowering duration of all French bean varieties. November sowing performed better in relation to yield components and seed yield than other sowing. BARI Jharsheem-1 produced the maximum seed yield (1734 kg ha-1) in 15 November which was statistically similar to 30 November sowing (1620 kg ha-1). The lowest seed yield (421 kg ha-1) was produced in BARI Jharsheem -2 from 30 December sowing. The highest seed yield was obtained from November sowing might be due to favourable optimum temperature for better flowering and pod setting that resulted in maximum seed.SAARC J.

The sowing date is an important factor for expanding the cultivated area of rapeseed and affects seed yield, oil content, and fatty acid compounds. Micronutrient elements play an important role in improving the vegetative and reproductive growth of the plant, especially under conditions of biological and environmental stresses. A two-year experiment (2014-2016) was performed to study the response of rapeseed genotypes to foliar application of micronutrients on different sowing dates. The treatments were arranged as a factorial-split plot in a randomized complete block design with three replicates. Three sowing dates of 7 (well-timed sowing date), 17, and 27 (delayed sowing dates) October and two levels of foliar application with pure water (control), selenium (1.5%), zinc (1.5%), and selenium+zinc (1.5%) were factorial in the main plots and five genotypes of SW102, Ahmadi, GKH2624, GK-Gabriella, and Okapi were randomized in the subplots (a total of 30 treatments). Seed yield, oil yield and content, oleic acid, and linoleic acid were reduced when rapeseeds were cultivated on 17 and 27 October, while the contents in palmitic, linolenic, and erucic acids, and glucosinolate increased (p < 0.01). a selenium+zinc treatment improved seed yield, oil content and yield (p < 0.01). The oil quality increased due to increased contents of oleic and linoleic acids under the selenium+zinc treatment (p < 0.01). The GK-Gabriella and GKH2624 genotypes are recommended to be sown on well-timed (7 October) and delayed sowing dates (17 and 27 October) and treated with selenium+zinc due to the higher oil yield, linoleic and oleic acids.

Peanut (Arachis hypogea L.) is an important nut crop extensively grown in rainfed regions of Pakistan. The crop requires low inputs; thus, could grow successfully under diverse environmental conditions. Due to pegging ability, peanut grows aggressively in sandy and sandy-loam soils. However, it has not introduced to Thal region of southern Punjab, Pakistan. A two-year field experiment was conducted to optimize sowing dates for two peanut genotypes (‘BARI-2016’ and ‘NO-334’) in Thal region (Layyah). Similarly, a yield trial was conducted at Chakwal where both genotypes are extensively grown. Five sowing dates (10th April, 1st May, 20th May, 10th June and 30th June) were included in the study. The highest seed yield was obtained with early sown crop (10th April) during both years. Pod formation reduced with increasing atmospheric temperature and no pods were formed on the plants sown on 30th June. Decreased pod formation seemed a major reason for low yield in late-sown crop. The highest yield was observed for the crop sown on 10th April, which was decreased by 40% for the crop sown on 1st May. Genotype ‘BARI-2016’ performed better for seed yield at both locations compared with ‘NO-334’. The results suggested that genotype ‘BARI-2016’ is more adaptive to arid and semi-arid condition under rainfed or irrigated conditions. Sowing peanut at optimum time would increase seed yield in arid and semi-arid regions. Nonetheless, ‘BARI-2016’ can be grown under rainfed and irrigated conditions successfully.

A field experiment was conducted during the winter (rabi) season of 2013-14 and 2014-15 at research farm Hisar, Haryana in a split plot design having four dates (Oct 15 and 25, Nov 5 and 15) in main plots and five nitrogen levels (0, 40, 60, 80 and 100 kg N/ha) in sub plots with three replications to study the effect of sowing dates and nitrogen levels on growth and yield of Indian mustard. Results revealed that October 15 sown crop resulted in significantly higher total plant biomass and its partitioning at different growth stages, yield attributes, yields and oil content. Delaying the sowing dates from October 15 to November 15 reduced seed yield by 39.3 percent. Among the nitrogen levels, application of 100 kg N/ha led to record higher total biomass and its partitioning at all growth stages and resulted in higher yield attributes and seed yield. Oil content decreased with increased levels of nitrogen.

Faba beans (Vicia faba L.), also known as fava beans, like other crops, are influenced by several factors: their genotype, environment, and management, as well as the interaction between these, have an important impact on seed yielding and seed quality traits. This study was conducted at three locations in South Italy between 2017 and 2019 to evaluate the sowing date effect on yield and yield components of three Vicia faba L., originating from cool climates. The results showed that seed yield (SY) and yield components declined with sowing delay. The crop’s environment (year × site) and management (sowing date) were found to explain 34.01% and 42.95% of the total seed yield variation, respectively. The data showed that the tested genotypes were positively influenced by the environment with sandy loam soil and early winter sowing date, resulting in either a greater number of SY and THS than in the other environment. The three faba bean genotypes showed tolerance to winter frost conditions in the two growing seasons.

The purpose of this paper and its companion1 is to describe how, in eastern Australia, soybean improvement, in terms of both breeding and agronomy, has been informed and influenced over the past four decades by physiological understanding of the environmental control of phenology. This first paper describes how initial attempts to grow soybean in eastern Australia, using varieties and production practices from the southern USA, met with limited success due to large variety × environment interaction effects on seed yield. In particular, there were large variety × location, variety × sowing date, and variety × sowing date × density effects. These various interaction effects were ultimately explained in terms of the effects of photo-thermal environment on the phenology of different varieties, and the consequences for radiation interception, dry matter production, harvest index, and seed yield. This knowledge enabled the formulation of agronomic practices to optimise sowing date and planting arrangement to suit particular varieties, and underpinned the establishment of commercial production in south-eastern Queensland in the early 1970s. It also influenced the establishment and operation over the next three decades of several separate breeding programs, each targeting phenological adaptation to specific latitudinal regions of eastern Australia. This paper also describes how physiological developments internationally, particularly the discovery of the long juvenile trait and to a lesser extent the semi-dwarf ideotype, subsequently enabled an approach to be conceived for broadening the phenological adaptation of soybeans across latitudes and sowing dates. The application of this approach, and its outcomes in terms of varietal improvement, agronomic management, and the structure of the breeding program, are described in the companion paper.

Genotype, environmental temperature, and agronomic management of parents influence seed yield in three-way cross hybrid maize seed production. The objective of this research was to generate information on the seed production of six three-way cross hybrids and their progenitors, adapted to tropical lowlands. Data on days to—and duration of—flowering, distance to spike and stigmas, and seed yield of five female single crosses and five male inbred lines were recorded for different combinations of four planting densities and four sowing dates in Mexico. The effect of planting density was not significant. The male inbred line T10 was the earliest and highest seed yield and T31 the latest, occupying second place in yield. The single crosses T32/T10 and T13/T14 were the earliest and had the highest effective seed yield. At the earliest sowing date, the females were later in their flowering, accumulated fewer growing degree days (GDD), and obtained higher yields since the grain-filling period coincided with hot days and cool nights. To achieve greater floral synchronization and therefore greater production of hybrid seed, differential planting dates for parents are recommended based on information from the accumulated GDD of each parent. The three-way cross hybrids were classified according to the expected seed yield of the females and the complexity in the synchronization of flowering of their parents.

The treatments consisting of 4 different dates of sowing i.e. S1-41th SMW, S2-44th SMW, S3-46th SMW, and S4- 48th SMW, & three variety i.e. V1-JT-90-1(Jeuti), V2-Yellow sarson (Benoy) and V3- TS-38. Growth, yield and yield attributing characters of toria varieties were influenced by different dates of sowing. S1 registered higher plant height (43.2 cm, 92.9 cm and 106.6 cm & 40.2 cm, 89.8 cm and 101.5 cm) and number of branch (3.8, 5.3 and 7.2 & 3.4, 5.1 and 6.9) at 30 DAS, 45 DAS and 60 DAS, respectively, during 2018-19 and 2019-20. Yield attributing characters like number of siliqua, number of seed per siliqua, 1000 seed weight (g) were gradually decreased with advancement of sowing dates. Among the three varieties V1 (Jeuti) recorded highest seed yield (8.9 q ha-1 and 8.1 q ha-1) and stover yield (23.4 q ha-1 and 22.2 q ha-1) in 2018-19 and 2019-20, respectively. Highest HI (28.5% and 25.8%) was recorded in S1 and lowest was recorded in S4 (20.7% and 14.6%).
