Effects of Seeding Density on Growth Attributes of Broadleaf Mustard in Nursery Bed

Abstract

The productivity of crops is highly affected by the seedling quality, which is governed by seeding density in the nursery. So, an experiment was conducted to explore the effect of seedling spacing in the growth attributes of Broad Leaf Mustard cv. “Marpha Chauda Paate” at IAAS, Lamjung Campus, during Oct 2018. Four spacing treatments viz 0.5 cm × 1 cm, 1 cm × 1 cm, 1.5 cm ×1.5 cm and 2 cm × 2 cm were arranged in RCB Design with 5 replications. Observation of seedling height, leaf area, leaf number, shoot & root fresh weights, shoot dry matter, and dry matter percentage from twenty-three days old seedlings were recorded. The total leaf area was estimated using the Image-J package. Data were tabulated in MS Excel and analyzed by Gen Stat. Treatments differed significantly in seedling height, shoot and root fresh weight, leaf area, root length, and shoot dry weight, while the number of leaves and dry matter percentage did not differ statistically. Maximum shoot fresh weight (1.09 g), shoot dry weight (0.11 g), leaf area (48.24 cm2), root length (4.89 cm), root fresh weight (0.03 g) per plant and shoot dry matter percentage (9.24%) were found in widest spacing (2 cm × 2 cm). However, seedling height was recorded higher in closer spacing. Therefore, the study of the overall characteristics asserted that the seed spaced at 2 cm × 2 cm produced superior seedling over all other spacings.

Effect of transplanting dates on growth, yield and quality of broad leaf mustard (Brassica juncea L. var. rugosa) varieties at Rampur, Chitwan, Nepal

“…So, it is realized that the selection of suitable BLM varieties having better qualitative as well as quantitative characters with their improved cultivation practices are very essential. Additionally, weather patterns have a significant impact on mustard productivity through its life cycle because different sowing dates offer varying environmental circumstances for a crop's growth and development in the same location (Panda et al, 2004;Prasad et al, 2018;Niraula & Timilsina, 2020). Being a long-day plant, BLM thrives in cool (15-18°C) temperatures rather than short day lengths.…”

Varietal performance of Broad leaf Mustard during winter season in plain region of eastern Nepal

“…Paudel et al (2016) reported that 58 different accession of BLM and 92 different accessions of rapeseed has been characterized and evaluated in National Agriculture Genetic Resource center (NAGRC), Khumatar, Nepal. Niraula and Timilsina (2020) stated that Broad leaf mustard is commonly grown as a transplanted crop from the nursery. The common variation that is seen in different variety of BLM is presence or absence of trichomes, leaf size (length and width), leaf petiole size, taste of leaf etc.…”

“…(Chalise et al, 2020). The productivity of Mustard is profoundly affected by prevailing weather conditions throughout its lifecycle (Niraula and Timilsina, 2020). 'Khumal broad leaf', 'Khumal red leaf', 'Marpha broad leaf' and 'Tankhuwa Rayo' are released varieties of BLM which have been cultivated since long time in Nepal (Shrestha et al, 2021).…”
