Abstract
Betel vine (Piper betel) cultivation and the consumption of betel leaves is a very traditional and widespread practice in India and many South-East Asian countries. The marginal and small farmers generally cultivate betel vine in their small holdings which provide them with a means of alternative cash earning to meet their day to day livelihood. Chewing betel leaves is an old habit of the people residing in subtropical countries. It is used in several traditional remedies for the treatment of stomach ailments, infections and as a general tonic. As betel leaf is directly chewed, there is a need to improve the leaf yield and to optimize the usage of manures for the leaf production. A study was taken up to assess the efficacy of some of the bio-inoculants in combination with inorganic fertilizers in betel vine cv. SGM 1 under an open system of deep trench method. Among the various treatments, Azospirillum @ 5 kg coupled with 100 kg each of P and K ha-1 had recorded the highest vine length (195.6 cm), more number of laterals per vine (22.3) and highest leaf yield ha-1 (44.7 lakh).
Highlights
Betel vine is an important commercial crop in India, Bangladesh and Sri Lanka
The important growth parameters like vine length, number of laterals and internodal length influenced the growth and productivity of the crop (Table 1). These growth parameters were differentially influenced by the bio-inoculants, which contributed to the growth, yield and quality of the crop
The highest vine length (195.6 cm) was recorded by the application of Azospirillum @ 5 kg coupled with 100 kg each P and K ha-1 (T6), and the lowest vine length (82.0 cm) was recorded by the application of 200:100:200 kg NPK ha-1 as inorganic form
Summary
Betel vine is an important commercial crop in India, Bangladesh and Sri Lanka. It is cultivated in almost all the South-East Asian countries on a limited scale. In the total production of betel leaves in India, Bio-inoculants on growth and yield of betel vine The present study was taken up to assess the efficacy of some of the bio-inoculants in combination with inorganic fertilizers in betel vine cv.
