“…The present study attempted to quantify the diversity of indigenous traditional crop species managed in nhalie agroforestry of Angami Nagas in Kohima district of Nagaland, India. Similar studies on agrobiodiversity in jhum cultivation have been earlier reported by various workers (Alam and Mohiuddin, 2009;Pradheep et al, 2014;Pandey et al, 2019). Forty crop species including 20 rice cultivars cultivated in jhum fields were reported from Chittagong hill tracts in Bangladesh (Alam and Mohiuddin, 2009).…”

“…Results of this study revealed that Kohima district of Nagaland had richer crop species (36) than that reported from other parts of Northeastern regions of India-Mon district of Nagaland (30 species), Churachandpur district of Manipur (32), Saiha in Mizoram (30) and Dhalai district of Tripura (19) (Pandey et al, 2019). One study documented 39 and 37 crop species from West Garo Hills district of Meghalaya and Upper Subansiri district of Arunachal Pradesh, respectively (Pandey et al, 2019). At the aggregate level, cereal and pulse crops in the sampled areas was observed to be more diverse and the mean diversification index value was found to be 0.63 on nhalie agroforestry land (Fig.…”

“…This study aimed to evaluate agrobiodiversity in nhalie agroforestry and documented 36 indigenous crop species belonging to 28 genera under 12 families. Traditional crop species cultivated in nhalie agroforestry were categorized into four crop types (Pandey et al, 2019) (Supplementary table 01). For example-field crops (12 species), vegetables and tubers ( 16), spices and condiments (7) and fruits (2).…”

Nhalie (shifting cultivation) and teizie (home garden) are the major forms of traditional agroforestry practices of Angami Nagas in Kohima district of Nagaland. They are characterized by high socio-cultural significance and prevalence of high degree of agrobiodiversity. The present study aims to assess agrobiodiversity and socio-cultural values of nhalie agroforestry of Angami Nagas in Kohima district of Nagaland, India. This study collected primary data from 60 households across five Angami villages by using methods of group discussion and participatory interview. Teizie and nhalie had higher average cultural ecosystem service values of 7.5 and 7.1, respectively. In term of economic ecosystem services, nhalie cultivation was perceived to be an important agroforestry practice with social use value (SUV) of 52.21. A total of 136 landraces of traditional crops belonging to 36 species were recorded. Two scented rice landraces (kethselha and rüluoo) and one sticky landrace (nhalenya) were reported. High overall Simpson’s Diversity Index value of 0.72 revealed high level of crop species diversity in nhalie agroforestry of Angami Nagas. Rice was the most common crop with the highest genetic diversity (22 landraces) followed by pumpkin, squash, taro, cucumber and maize. Nhalie agroforestry could serve as the major reservoir of traditional crop species and contribute to the conservation of these valuable traditional crop species on-farm. Further, the existing agrobiodiversity managed with the traditional wisdom of Angami Nagas in nhalie agroforestry systems is required to be preserved and disseminated for sustainable use of bioresources.

Improved agronomic practices and high yielding rice varieties maintain soil health and enhance yield and energy use efficiency under shifting cultivation landscapes of easternHimalayas

et al. 2023

Low productivity, depletion of soil fertility, and inefficient energy use are the major challenges of fragile Jhum (shifting cultivation: 280 M ha worldwide) agro‐ecosystems in north eastern Himalaya. Farmers' participatory field trials were conducted in sloping lands of Meghalaya, India over 3 years to identify suitable agronomic management practices and input responsive rice genotypes for sustaining soil health and enhance carrying capacity of Jhum land. Eleven genotypes of rice (six high yielding varieties [HYVs] and five landraces) were tested under two management practices, namely, improved Jhum (line‐sowing in contour, 50% recommended dose of nutrients (RDN) + farm yard manure 5 Mg ha−1 with two hand weeding operations) and traditional Jhum (broadcasting, no manure/fertilizer/pesticides, and single hand weeding) as reference. Improved Jhum practices significantly increased (p = 0.05) rice yield (103.8%–133.7%), improved soil health, farm profitability, net energy output, and energy intensity. The HYVs of rice, namely, RCM 5, Bhalum‐3, and IURON 514 (1.92–1. 96 Mg ha−1) significantly out yielded local landraces, namely, Mannar, Kbaslu, Kba Khasi, Pnahiong, and Pnahlaispah (1.44–1.65 Mg ha−1). The soils under improved Jhum practices had significantly higher SOC (16.9 g kg−1), available N (278.2 kg ha−1), P2O5% (12.8 kg ha−1), K (217.1 kg ha−1), and more water infiltration rate (74.1 mm h−1) over traditional practice after 3 years of our present study. The rice yield for second and third year of cropping were also significantly higher (p = 0.05) under improved Jhum practices (2.23 and 2.01 Mg ha−1, respectively) as compared to traditional Jhum. The net income enhanced by 53% and 85 to 104.6% owing to adoption of improved Jhum and HYVs over local practice and genotypes, respectively. Hence, growing HYVs of rice, namely, RCM 5, Bhalum‐3, and IURON 514 along with improved agronomic practices are recommended for achieving higher productivity, extending carrying capacity, and sustaining soil health in Jhum ecosystems of north eastern Himalaya.
