Randomised complete block trial of GA3 and NAA foliar sprays on okra cv. Parbati at the Agriculture Research Station, Tarahara, Sunsari. The 100 ppm GA3 + 100 ppm NAA combination produced the tallest plants and largest leaves, while NAA at 150 ppm alone gave the most pods per plant and the highest pod yield (9.55 t ha−1 against 3.39 t ha−1 in the control, a 181.7% increase).

Randomised complete block trial of nine spring rice genotypes against the released check Hardinath-1 at Gadhi-3, Sunsari. IR-19-A-5000 gave the highest grain yield (6.38 t ha−1) with the earliest maturity (117.3 days) and the lowest sterility (16.56%), and the yield ranking was driven by harvest index rather than total biomass.

Effect of Mulching Materials on Population Dynamics of Insect Pests and Natural Enemies and on Growth and Yield of Lettuce (Lactuca sativa L.) in Lalitpur, Nepal

Randomised complete block trial of black plastic, silver-on-black plastic, rice straw and sawdust mulches against bare soil on spring lettuce at Khumaltar, Lalitpur. Silver plastic kept aphids, cutworms and Helicoverpa armigera lowest, while rice straw favoured coccinellid predators but also mealybugs and cutworms. Rice straw and silver plastic gave the highest final-harvest yields (13.07 and 12.84 t ha−1 against 7.09 in the control), and sawdust returned the best benefit–cost ratio (1.83).

Randomised complete block experiment on mature Bombay Green mango trees at the Tropical Horticulture Centre in Nawalpur, Sarlahi. GA3 at 35 ppm produced the highest fruit retention, BAP at 15 ppm produced the highest yield, and NAA at 35–50 ppm most improved sweetness and internal fruit quality.

Farmers' Perception of Fall Armyworm (Spodoptera frugiperda) and Its Management Practices on Maize in Chitwan District, Nepal

Household survey of 60 maize growers in Chitwan. Fall armyworm ranked among the top insect pests, yet insecticides were the only common response and no farmer reported a cultural or biological practice. Guidance came from fellow farmers and agrovets, not public extension.

Factors Influencing Farmers' Decision on Sowing Time and Variety Selection for Spring Season Rice in Rautahat District, Nepal

Survey of 91 spring rice growers in Rautahat. Irrigation and seed availability were significantly associated with maturity preference, and sowing time affected production cost and productivity but not family income. Drought risk and high input cost were the leading constraints.

Production economics of two F1 hybrid cucumbers from a survey of 60 farmers in Katahari and Jahada, Morang. Both were profitable (benefit–cost ratio 2.40 for Chandani, 2.19 for Raja), with intercultural labour the main driver of productivity. Lack of training and extension, and of storage, were the leading constraints.

Agricultural Mechanization Status and Adoption Constraints in Maize Farming: Evidence from a Hill Municipality of Nepal

Survey of 100 maize-farming households in Satyawati Rural Municipality, Gulmi, a PMAMP maize zone. Power tillers dominated tillage (69%) but post-harvest mechanisation reached only 13%. Farmers rated the bullock-drawn plough as the most agronomically effective, and the main barriers to adoption were lack of extension advice (66%) and training (44%) rather than cost (17%).

Review of 2019–2025 evidence on rice mechanisation in Nepal. Land preparation (86–100%) and threshing (65–91%) are largely mechanised, but transplanting, weeding and fertiliser application remain manual. Training and subsidies were the strongest drivers of adoption, while land fragmentation, machinery cost, weak service networks and gendered access held it back. Spring rice is a promising target for mechanisation.
