Nepalese broom grass Thysanolaena Maxima is a multipurpose perennial cash crop that belongs to the family Poecea. It is found growing along steep hills, sandy banks of rivers and damp steep banks along ravines. It is widely distributed throughout Nepal but only up to an altitude of 2000 metres. The grass can be grown on severely degraded and marginal lands. Broom grass tends to grow in tussocks, with 4-5 tussocks in a 100-metre radius and is harvested during the winter seasons between January and March.
In order to grow broom grass the slips in the planting site must be clear of weeds and debris. Planting the broom grass slips in fertile soil ensures the best yield. It is usually planted at the beginning of monsoon season during the months of May to June as the soil has the best moisture for plant genesis. One month before planting pits of 30m cubed are dug up and left for weathering. On hilly land the pits should be placed about 1.5 x 2m apart along the contour lines or trace bunds, while on fertile land the best spacing is 2.5m x 2.5m. Farm yard manure and 10% BHC fertilizer at 10 grams per pit are mixed into the pits before planting the seeds.The plant becomes rather low maintenance after planting. The plant requires to be weeded 3-4 times in the first year and annually in the following years. Manure can be applied to the soil during the second weeding to provide the best yields in the first year. The pits need to be fenced off to protect the plants from grazing.
The mature panicles which turn light green or red are harvested in the winter season from January to March. The timing of the harvest is essential as if the plant is harvested prematurely (5–7 days) their production declines, while if it harvested late it will begin to wilt. The panicles are either harvested by cutting above the soil separating the panicle for stem or pulling the panicles out by hand. It is important to make sure the young sprouts are not damaged or the plants uprooted during harvest.The yield will be the lowest in the first and fifth year with the highest in the third.
