“…The lowest yield was of month May (2.4 t/ha) (Figure 2). This results was confirmed with the findings of Dahmardeh and Dahmardeh (2010) who reported that the maximum grain yield (8.84 t/ha) was obtained from the 5 August sowing date that was not statistically on a 20 July and 20 August. Winter maize has higher production potential.…”

Genotypic yield potential of maize varieties is greatly affected by sowing dates. In order to investigate the effects of sowing dates and varieties on the grain yield of maize, the field experiment was carried out at research field of National Maize Research Program (NMRP), Rampur, Chitwan, Nepal from April 2009 to March 2010. Three varieties namely Rampur Composite, Arun-2 and Gaurav were sown at every week. The results of experiment showed that interaction effect of variety and sowing date on grain yield of maize was significant. Rampur Composite produced highest grain yield (6.1 t/ha) in August and lowest yield (2.6 t/ha) in May. Similarly Arun-2 produced highest yield (4.6 t/ha) in August and lowest yield (2.1 t/ha) in May. Gaurav produced highest grain yield (5.1 t/ha) in September followed by 4.9, 4.8 and 4.6 t/ha in February, July and August respectively and lowest yield (1.5 t/ha) in November. The sowing date was highly significant on grain production. The highest grain production was 5.1 t/ha in August followed by in February (4.9 t/ha), September (4.6 t/ha) and March (4.4 t/ha) respectively. The lowest grain yield was produced in May (2.4 t/ha). Therefore it was concluded that August planting was best for higher grain production of maize varieties (Rampur Composite, Arun-2 and Gaurav) in terai region of Nepal.

“…Similar results are also presented by Dahmardeh and Dahmardeh [32]. Banga et al [33], Sharma and Jain [30] and Carson [12] reported that control of weeds manually, herbicides use and application of allelochemicals significantly improve the grain yield as compared to untreated plots.…”

Peral millet being drought tolerant has substantial potential to contribute in food security ensuring the food, fodder and nutritional value in different Asian and African countries. Susceptibility to abiotic and biotic factors and low productivity are the main reasons for decreasing productivity and area of millets. In this context, evaluation of the effect of weed control practices and varying sowing dates on grain yield of kharif season grown pearl millet (Pennisetum americanum L.) was demonstrated at post graduate agriculture research station, University of Agriculture, Faisalabad during 2015. Forage pearl millet was sown at three different sowing dates i.e. mid-June, end of June and mid-July and four weed control practices viz. weedy check (no weeding), twice hoeing at 15 and 30 days after sowing (DAS), weed control using herbicides i.e. application of Atrazine (Awax 38 SC) @ 330 g a.i. ha −1 at 15 DAS, and twice foliar applications of 10% Sorghum water extract (Sorgaab) (at 15 and 30 DAS). The experiment was laid out in randomized complete block design (RCBD) under split plot arrangement, comprising of three replications. The treatments with varying sowing dates were randomized in main plots and weed control practices were in subplots. Results showed that the highest plant height (279.51 cm), leaf area (2777.80 cm 2), fresh weight of leaves per plant (155.57 g), maximum number of grains per head (3162.0) and grain yield (3419.7 kg•ha −1) were obtained in the treatment combination of 30th June sowing × twice weed hoeing (at 15 and 30 DAS) while, maximum 1000-grain weight (8.45 g) was observed in treatments where weeds were controlled by hoeing

“…Since winter wheat had better water productivity and farm economic returns than winter barley, there is a great advantage in choosing autumn planting crops while winter wheat needs to be planted early compared with winter barley. The results of this study confirmed that planting of forage maize in early July compared to earlier dates led to maximum values of DY and FB; the results of Dahmardeh (2010) in south-eastern Iran indicated that the highest yield of maize was obtained from 5 August, while the results of the AquaCrop model indicated that it is not possible to plant forage maize after 5 July in the study area owing to the GDD requirement of forage maize. Figure 5 also shows the values of DY and FB for each crop with various planting dates.…”

Lake Urmia in Iran has faced extreme water loss in recent years due to overuse and mismanagement of water resources, particularly in agriculture. In this study, three strategies including irrigation depth reduction, changing planting dates and crop rotation in crop patterns of Urmia city were assessed for improvement of water productivity to mitigate the crisis of Lake Urmia. For this purpose, the AquaCrop simulation model was applied. The effects of the three strategies were investigated with four indicators: (i) total water productivity (TWP); (ii) economic water productivity (EWP); (iii) farmers' benefit (FB); (iv) dry yield (DY). The results showed that a 60% reduction of current irrigation depth for winter wheat, winter barley, forage maize and tomato and a 40% reduction for sunflower substantially increased TWP and EWP without considerable reduction in DY and FB. Early planting dates for autumn planting crops (wheat and barley) and delaying planting dates for spring planting crops led to a decreased irrigation requirement and increased benefit from rainfall. For the autumn planting pattern, selecting winter barley reduced water consumption by 2170 m3 ha−1 compared to winter wheat, and for the spring planting pattern, selecting forage maize decreased water consumption by 2080 and 3150 m3 ha−1 compared to sunflower and tomato, respectively. © 2018 John Wiley & Sons, Ltd.
