Berseem Clover

Berseem clover (Trifolium alexandrinum), simply called berseem across Punjab and Sindh, is the cool-season legume that keeps Pakistani dairy yards in green fodder from November through April. POWO records it as native from Egypt to Pakistan, an annual of the subtropical biome that has been the backbone of Nile-valley fodder rotations for thousands of years.¹ For a food-forest plot it is the obvious winter cover crop on any bed that will sit empty between the kharif and rabi cash crops.

Where it thrives

Berseem is a rabi-season crop suited to the Punjab plains, Sindh coast, and the warmer end of the Pothohar plateau. Feedipedia reports an optimum rainfall band of 550 to 750 mm and a working temperature range that excludes hot summer heat, with some cultivars surviving frost to about minus six degrees and a few hardier types down to minus fifteen.² It wants a deep loam, tolerates moderately alkaline soils common in the canal-irrigated districts of Punjab, and responds strongly to irrigation rather than rainfed conditions.²

Role in the system

Berseem sits in the groundcover layer as a pioneer nitrogen-fixer. Drilled into a bed after the monsoon-season crop is harvested, it builds a dense low canopy that smothers winter weeds, scavenges nitrogen, and feeds the soil microbiome through root exudates and rhizobial nodulation. In a rotation with oats it can return on the order of 43 kg N per hectare to the subsequent cereal, lifting a following maize crop by around ten percent.² Treat it as the cool-weather understory in a guild that already has a perennial tree or shrub layer above.

Growing it

Decisions worth getting right. Sow seed in early autumn, mid-October on the Punjab plains, once daytime temperatures drop below the mid-thirties.² Berseem is only propagated by seed; broadcast at about 20 to 25 kg per hectare onto a well-prepared seedbed or drill into standing stubble. Inoculate with the appropriate rhizobium strain if the bed has not grown clover before.³ Irrigate immediately after sowing and then every two to three weeks; ten to fifteen irrigations across the season give the best fodder yields.² Highly branched cultivars such as Miscawi or the Pakistani-bred Anmol-91 can be cut four to six times across the winter at six-week intervals, starting once the canopy reaches about 30 cm.²

What you get

Under good irrigation, multi-cut berseem produces 8 to 10 tonnes of dry matter per hectare across a single rabi season, or roughly 60 to 80 tonnes of fresh forage.² The main product is high-protein green fodder for buffalo and dairy cattle, comparable to alfalfa but without bloat risk.²⁴ What stays in the ground is fixed nitrogen, improved soil tilth, and a clean weed-free bed for the following spring crop.

Sourcing notes

Buy fresh certified seed each season from Punjab Seed Corporation or NARC outlets; berseem seed loses viability fast in hot storage. Good companions are oats or barley drilled into the same bed for a mixed silage stand. Keep it out of beds heading into a summer legume crop the next season to avoid rhizobial saturation and disease carry-over.
