ABSTRACT
Afield experiment was conducted during bona season of 2019/2020 and 2021/2022 at two location Agarfa sub-site and Sinana on station to evaluate the integrated effects of pre-emergence herbicides and hand-weeding on weed control, yield components, yield, and their economic feasibility for cost effective weed control in field pea. The treatments consisted of three dual gold rates (1, 2 and 3 liter per hectares) and three times (0, 1and 2 times hand weeding). The experiment was laid out in a factorial arrangement of RBCD with three replications. Results indicated that Dual-gold 2 liter per hectare supplemented with hand weeding at 25-30 days after crop emergence resulted in the highest grain yield and economic benefit. However, in case labor is constraint and Pre-emergence herbicide is timely available, pre emergence application of Dual-gold 2 liter per hectare should be the alternative to prevent the yield loss and to ensure maximum net benefit for the producers. Thus, the result of this study, it can be tentatively concluded that herbicides application is an integral part of farmer’s pulse crop management in modern agricultural systems.

ABSTRACT
The experiment was carried out at the existing plantation of Hill Agricultural Research Station at Khagrachari during 2021-22 to find out the pruning method for maintaining tree size and impact of pruning on yield and quality of coffee. Coffea canephora (syn. Coffea robusta) commonly known as robusta coffee from the existing coffee orchard of HARS, Khagrachari was selected for the study. All treatments produced higher yield than control treatments. Maximum yield was found in P3 (9.14 kg/plant) followed by p5 (8.86 kg/plant). On the other hand, control treatments produced lowest amount of coffee per plant. All treatments showed higher yield than control treatment. Yield increased maximum 49.7% found in P3 treatment over control. In a nutshell the present finding shows that pruning increase yield potentiality of old coffee orchard.

ABSTRACT
This study conducted a thorough assessment of how germination and growth of shoots and roots in eight vegetable crops are influenced by aqueous and methanolic extracts from Chromolaena odorata. Findings reveal a broad spectrum of germination responses to leaf extracts (13.3% to 86.7%), signaling the intricate dynamics at play between the plant's chemical compounds and the germination mechanism. Notably, Cucumis sativus (70% at AQE 5%) and Phaseolus vulgaris (56.70% at AQE 10%), displayed remarkable resilience and even stimulation of germination under specific extract concentrations, suggesting a potential selective stimulatory effect. For root extracts, the introduction of AQE and MTE decreased germination percentages across crops. A. esculentus had the highest germination rate at AQE 20%, significantly lower than the control (60%). Solanum. melongena tolerated AQE 5% best, while MTE 20% was most inhibitory. Conversely, Solanum lycopersicum experienced complete germination inhibition in both AQE and MTE of leaf and root extracts, indicating species-specific vulnerability to the allelopathic compounds within the extracts. Shoot growth mostly declined with higher extract concentrations, except in Solanum melongena, Capsicum annuum, and Zea mays, which saw increased shoot lengths under certain conditions. Root growth responses were mixed; Abelmoschus esculentus and Zea mays showed growth increases at some concentrations, in contrast to Cucumis sativus and Solanum melongena, which had limited growth. Methanolic extracts had a stronger inhibitory effect, likely due to their potent bioactive compounds. These findings highlight the importance of extract type, concentration, and crop species in weed management, providing insights for sustainable agricultural practices.
