In this research work, we attempted to know the positive response of putrescine on plant growth and flowering of annual flower gypsophila. Putrescine is important because it has been shown that exogenous treatment can enhance the production or accumulation of bioactive chemicals that show a positive impact on plant growth and development. Significant results were obtained in various growth and flowering parameters of annual gypsophila due to foliar treatment with putrescine. Maximum plant height, maximum plant spread, maximum number of leaves perplant, maximum number of primary branches and secondary branches per plant at 60 DAT and 90 DAT as well as maximum number of flower clusters per branch and maximum number of flower clusters per plant was recorded from 1.50 mmol of putrescine application. © 2023 Indian Council of Agricultural Research.

Impact of salicylic acid and kinetin on morpho-physiological traits, flowering patterns and seed yield in salvia (Salvia splendens)

A field experiment was carried out to study the effect of salicylic acid and kinetin on morpho-physiological, floral dynamics, and seed yield in Salvia (Salvia splendens) at Banaras Hindu University Varanasi, Uttar Pradesh, India during 2021-22. A randomized block design (RBD) with three replications was used in the design of the experiment. The treatments consisted of varying concentrations of salicylic acid (10 ppm, 20 ppm, 30 ppm, and 40 ppm) and kinetin (5 ppm, 10 ppm, 15 ppm, and 20 ppm) and a control of water spray only. Vegetative growth, flowering, and seed yield parameters were observed at 60 and 90 days after treatment (DAT). The ornamental value of plants was determined largely by plant growth regulators. Results showed that a 15 ppm kinetin spray enhanced plant height (75.34 cm) and plant spread (48.91 cm) at 90 DAT. Salicylic acid at 20 ppm gave the highest number of flower spikes per plant (93.33), number of flowers per plant (1746.00) and fresh weight of flowers (3.57 g). In addition, seed yield per plant (17.39 g) and test weight (2.94 g) were highest at 20 ppm salicylic acid. The research sought to determine the effects of kinetin and salicylic acid on plant responses and to establish a baseline for future work on the mechanisms of action of plant growth regulators (PGRs) in the growth and development of annual flower crops whose demand and scope are increasing. © 2025, Society for Advancement of Horticulture.

Study on the physiological impact of salicylic acid and kinetin on growth dynamics, floral morphogenesis and seed yield of Sweet William
(Indian Academy of Horticultural Sciences, 2024) Priyanka Kumari; Thupten Tsomu; A.K. Singh; Ampee Tasung; Ashim Debnath; M.M. Sharma; Samikhya Bhuyan; Duyi Samyor; Tijeshwari Sahu; Yogendra Kumar
This study investigated the impact of salicylic acid and kinetin on the growth, flowering, and seed yield of Sweet William (Dianthus barbatus L.). The concentration of SA ranged from 10 to 40 ppm and for kinetin it was 5 to 20 ppm alongwith a control. It was revealed that SA at 20 ppm induced the maximum plant height at 60 days after treatment (DAT), while kinetin at 15 ppm exhibited the highest plant height at 90 DAT. SA at 20 ppm influenced primary and secondary branches, stem diameter, and leaf count. It accelerated bud initiation at 55 DAT and prompted the earliest floral anthesis at 66.16 DAT, acting as a blooming time regulator. Kinetin at 20 ppm stimulated the highest number of flowers per plant (543.83) and increased the fresh and dry weight of flowers at 10 ppm. Additionally, kinetin at 20 ppm enhanced the total seed production. SA at 40 ppm recorded the highest seed yield per plant and 1000-seed weight as well. Optimal treatment involves SA at 20 ppm for enhanced, while kinetin at 20 ppm positively influences flower and seed production. © 2024, Indian Academy of Horticultural Sciences. All rights reserved.
Traditional soil and water conservation by tribal farmers in Arunachal Pradesh: A case study on erosion control

Mountainous regions require more attention to protect, restore, and develop than any other ecosystems. Prioritizing techniques and practices that improve productivity while protecting the environment is essential in this regard. A study was conducted to identify traditional agricultural practices and soil and water conservation measures among Galo tribal farmers in Arunachal Pradesh, India. Data were gathered through surveys, group discussions, interviews, and field observations from 150 farmers across three elevation zones (low, medium, and high) during 2022-23. Farmers have inherited and implemented various conservation practices, including wetland rice cultivation (Esiarik), contour farming, mulching, agroforestry, vegetative barriers, bamboo channel irrigation systems (Kombo), mixed crops, water-harvesting structures, and traditional soil conservation methods. This study documents and analyses the elevation-specific indigenous conservation practices of Galo tribal farmers. These practices are widespread across all elevation zones, indicating farmers’ strong reliance on traditional conservation methods and their economic benefits. The outcomes of this study have significant implications for regional strategies related to sustainable land management. © 2025, National Institute of Science Communication and Policy Research.
