A gricultural farming of Pakistan plays a central role in its economic development. Currently, agriculture has a 19.2% share to Gross Domestic Product (GDP) that provides 38.5% employment (GoP, 2020-21). Agricultural sector of Pakistan is continuously expanding because of more associated sectors out of which livestock is the major one. There is a huge gap in the domestic production of fresh forage and its demand, which needs to be optimized for addressing the need of rapidly growing livestock. Livestock is a crucial associated sector of agriculture contributing about 11.5% in GDP. It accounts for 60.1% share of agriculture to GDP (GoP, 2020-21). Due to lack of knowledge regarding approved forage cultivar, optimum crop density, quality seed, and recommended production technology are major Abstract | Berseem (Trifolium alexandrinum L.) in Pakistan is a vital forage Yield gap because of its palatable and nutritional nature that provides forage in repeated cuttings almost year round is mandatory to be addressed, that is the main focus of the present investigation. The recent investigation was performed to assess the impact of seeding rate consequently plant density on forage and seed tonnage in order to enhance the net return. Experiment treatments comprised of seven seed rates viz., 10, 12.5, 15, 17.5, 20, 22.5 and 25 kg ha -1 . Sowing was completed up to 7 th October in each year of study using seed of new cultivar Punjab Berseem. All forage contributing characters were recorded at each cut of fodder and grain tonnage at harvesting were evaluated and documented. Data of agronomic characteristics and economic returns from all planting densities revealed significant differences. The results indicated that 15 kg ha -1 seed rate produced maximum values of heads m -2 (462.50) which was at par with 17.5 kg ha -1 (450.0 m -2 ), tillers m -2 and enhanced forage production 2.85% over control (i.e. 20 kg ha -1 ). Higher grain production (0.85 t ha -1 ) was noted by seeding rate 17.5 kg ha -1 , nevertheless, it was at par with control. The economic data revealed a highest benefit cost ratio of 3.99 under 17.5 kg ha -1 seeding rate compared to control.

“…An increase in weight per plant of Sorgum-2011 was due to greater plant height, leaf area, and stem diameter. Similarly, Gondal et al(2017) showed significant differences among sorghum cultivars regarding weight per plant. Furthermore, Ayub et al(2010) found non-significant differences in plant dry weight among six sorghum varieties, while Afzal et al (2012) compared different sorghum cultivars.…”

Planting patterns and different cultivars play a significant role in forage crops quality and productivity. Therefore, we conducted a field experiment under different planting patterns and cultivars to evaluate sorghum crop yield, yield components, and quality at Agronomic Research Farm, Department of Agronomy, University of Agriculture Faisalabad, Pakistan, in 2015. The experiment consists of three sorghum cultivars (Jawar 2002, Sorghum-2011, and JS-2002) with a seed rate of 75 kg ha-1 at different planting patterns (P1=60 cm × 20 cm, P2=50cm × 24 cm, and P3=340 cm × 30 cm). Results showed that sorghum 2011 resulted in higher growth and qualitative attributes than other cultivars. For example, increase in plant height (237.11 cm), dry weight plant-1 (40.61 g), forage yield (57.66 ton ha-1), crude protein contents (6.12 %), fiber contents (32.12 %) and ash contents (8.73%) was observed in sorghum 2011 as compared to other cultivars. Whereas, among planting pattern P3 (40 x 30 cm ) produced maximum plant height (236.33 cm), leaves plant-1( 13.66), stem diameter (1.09 cm), forage yield (55.52 ton ha-1), dry matter yield (18.53 ton ha-1) and crude protein contents (6.06 %) as compared to P1 and P2. This study suggested that the cultivar sorghum 2011 with a planting pattern of 40 x 30 cm is a promising option to improve yield, yield components and quality of sorghum crop.

“…These circumstances were presumably because the research area was a coastal area which contained a lot of sand, neither tillage nor notillage was different. The land has not been used used for 6 months, so the nutrients were available and there was no competition between sorghum plants even though the spacing was different [33,34]. Irwan et al [9] stated that a good spacing really depends on the level of soil fertility, soil cultivation, fertilization, and the varieties used.…”

“…An increase in population of more than 150,000 plants per hectare tends to increase yields though it is not that large [32]. The spacing did not have a significant effect on the growth of sorghum, but the spacing had a significant effect on crop yields per plot [33]. Spacing of 50 cm x 30 cm (133,333 plants/ha) gave higher yields per plot of 4.30 tons/ha compared to the spacing of 75 cm x 25 cm (106,666 plants/ha) of 3.50 tons/ha [31].…”

Sorghum (Sorghum bicolor L.) is a cereal plant that has high adaptability on marginal coastal soils. Sorghum can be used as a source of food and feed, while high biomass production has the potential to be used as an industrial raw material for bioethanol production. The objective of this research was to study the combination of land preparation methods with spacing of sorghum in coastal land. The study was done at Muara Bangkahulu District, Bengkulu City. Initial observation found that the research field was sandy soil and dominated by Imperata cylindrica. The experiment was arranged in a split plot design and replicated 3 times. The main plots were land preparation methods that included no-tillage using glyphosate at 1.5 kg/ha for land clearing, using paraquat at 1.0 kg/ha for land clearing, and two times tillages or conventional tillage. Sub plots were variations of spacing that included 50 cm x 20 cm, 60 cm x 20 cm, and 75 cm x 20 cm. The results showed that there was no interaction between land preparation methods with variations of spacing on the growth of sorghum. However, the method of land preparation significantly affected only the leaf area, where the treatment of notillage using glyphosate and paraquat increased leaf areas and was significantly different from conventional tillage. Variation of spacing also affected leaf areas and panicle length where the broadest leaf was 9,064.56 cm 2 and the longest panicle was 20.37 cm observed at 70 cm x 20 cm spacing. Thus, no-tillage using glyphosate or paraquat for land clearing are recommended for growing sorghum in coastal lands.
