Many factors affected the yield of lentil under the study area. The following factors are listed as mentioned.
Operational cost
Tillage cost for preparatory
From Table 1, it is clearly revealed that in Raha block, the preparatory cost of lentil field was significantly higher (Rs.3435.00/ha) as compared to others blocks of Nagaon and Hojai district. This might be due to poorly drained soil, requiring more tillage than other blocks.
Priya et al. (2022) also stated that because of a greater number of cultural operations and labour charges leading to higher cost of cultivation with chickpea and oats fodder (2:1) than other intercropping method.
Irrigation before sowing
In Raha block, pre-sowing irrigation cost is higher at Rs.345.00/ha among the other blocks of study area followed by Kathiatali, Pakhimori, Lanka and Bajiagaon at Rs.310.00/ha, Rs.250.00/ha, Rs.255.00/ha and Rs.210.00/ha respectively indicating all were on par with each other. Bajiagaon block (Rs.210.00/ha) need less irrigation cost before sowing which might be due to flat area in the lentil field which retain moisture resulting in less cost involvement.
Cost of sowing
The cost of sowing is highest at Bajiagaon block (Rs.1240.00/ha) than Raha, Kathiatali and Pakhimoria blocks of Nagaon district but on par with Lanka block (Rs.1234.00/ha) of Hojai district. In Bajiagaon block, sowing cost is highest might be due to labour availability and wage rate which significantly increase the cost of sowing.
Fertilizer application, manual hoeing
Fertilizer application was highest in Pakhimoria followed by Raha, Kathiatali and Bajiagaon respectively. This might be due to input availability and improper agricultural practices prevails in those areas, where extension services might be needed to reduce cost and increase efficiency. But among all blocks of Nagaon and Hojai district, at Pakhimoria block, manual hoeing is lowest (Rs.155.00/ha).
Harvesting, threshing and transportation cost
The harvesting cost was higher at Nagaon district (Rs.4458.00/ha) than Hojai district (Rs.4321.00/ha). Among all blocks of Nagaon district, harvesting cost was highest at Kathiatali block (Rs.4489.00/ha) followed by Pakhimoria (Rs.4489.00/ha), Raha (Rs.4450.00/ha) and Bajiagaon (Rs.4326.00/ha) respectively. It was estimated that threshing cost was higher at Hojai district (Rs.4876.00/ha) than Nagaon (Rs.4494.50/ha). Similarly, transportation charges also higher in case of Pakhimoria (Rs.445.00/ha) block than the other blocks.
Input cost and correlation between input and yield
Independent variable cost is presented on Table 3 and it is seen that highest cost was incurred in seed cost at Kampur block (Rs.34350.00/ha) followed by Raha block (Rs.33000.00/ha) in Nagaon district. However, the rest blocks in Nagon and Hojai were on par. Similarly, cost of fertilizer application and seed treatment were on par in all the blocks with exception in Kathiatali block in cost of fertilizer and its application which was lowest (Rs.778.00/ha). Seed cost was highest among all the independent variable and chemical weeding hoeing and manual, insecticide cost, disease cost are lowest among all independent variable. Similar results were observed in the research findings of
Ghimire et al., (2024) and
Leharwan et al. (2023).
Table 2 explained the correlation between dependent and independent variables. It was observed that FYM quantity, irrigation and manual weeding had positive and significant impact on yield whereas the other four independent variable
viz., input used, DAP (kg/ha), chemical weeding and insecticide had found insignificance impact on yield. FYM quantity (r= 0.243, P<0.05), Irrigation (r=0.181, P<0.05) and Manual weeding (r=0.457, P<0.05) had positive and significant impact on yield.
Singh et al. (2016) conducted a study on lentil based existing cropping system and observed that in lentil-based cropping systems (B: C ratio -3.11-3.77) was economically efficient than non-lentil-based cropping system (B:C ratio -1.17 to 1.72).
Table 3 depicted the correlation between inputs and yield, where yield was found to be positively correlated with FYM quantity (r = 0.243, P<0.0001), manual weeding (r=0.181, P<0.05) and irrigation (r = 0.272, P<0.0001). It means that the lentil growers in Central Brahmaputra Valley must take care of application of FYM in their fields, irrigation and manual weeding in order to get good yield.
Fig 1 shows the distribution channel of the lentil from producer (farmers) to the consumers through different intermediaries. The channels identified were as follows:
1. Producer-consumer.
2. Producer-village merchant-retailer-consumer.
3. Producer-village merchant- Commission Agent-retailer-consumer.
4. Producer-village merchant-Commission Agent- Wholesaler-retailer-consumer.
Producer-consumer
This channel was the shortest channel which accounted for 55 percent of the total total lentil marketed. In this channel larger amount of lentil was sold to consumer.
Producer-village merchant-consumer
The study of this channel showed that 10.00 per cent of the total produced lentil flowed through this channel. The village merchants bought from the farmers and directly sold to the consumer in local market.
Producer-village merchant-commission agent-retailer-consumer
This channel showed that 23.00 per cent of the total marketed lentil flows from this channel. The village merchant purchased lentil from farmers and sold to the Commission agent and Commission agent sold to retailer and ultimately retailer sold to the consumer.
Producer-village merchant-commission agent-wholesaler-retailer-consumer
It was found that 11.50 per cent of total lentil flowed through this channel from farmer to consumer which was the longest channel.
The data depicted in Table 4 and Table 5 represent marketing cost, margin of different intermediaries along with price spread. It was depicted in Table 5 that Channel 1 is the best efficient channel as price spread is 0 as the difference beteen the price paid by the consumer and price received by the producer is called price spread. Price spread is different from channel to channel. The result revealed that highest marketing cost was observed in Channel IV while highest margin was observed in Channel I. Marketing efficiency was observed 1.019, 2.955, 1.746 and 1.467 for Channel I, Channel II, Channel III and Channel IV respectively. In case of Channel II and channel III cost incurred was almost equivalent but margin difference is high. In channel I, price received by the farmers are highest indicating that channel I is the most efficient marketing channel without middlemen involvement. This finding is in conformity with
Singh et al. (2020) and
Verma et al. (2023) that marketing channel-III (producer and processor only) was found most efficient with an efficiency of 12.03. The producers’ share in consumer rupee is highest in Channel I at 81.82 per cent followed by Channel II, Channel III and Channel IV at 62.50, 57.89 and 54.46 per cent respectively.
