2020
Lentil (Lens culinaris Medik) is the important pulse crop grown mainly on residual soil moisture in rabi season. There is an ample scope for expansion of area under pulse crop like lentil in conserved soil moisture in North Eastern Hill Region of India where a large part of area remains fallow after the kharif season rice. In view of this, a field evaluation of nine most promising lentil varieties was conducted under conserved soil moisture at College of Horticulture & Forestry, Pasighat, Arunachal Pradesh, India during 2015-16 and 2016-17 to identify the most suitable lentil varieties under residual soil moisture condition in rice fallows. The data of two year experiment revealed that lentil variety IPL-316 exhibited maximum seed yield (11.03 q/ha) with minimum days to maturity (116 days). The other varieties with considerably fair seed yield performance were DPL 62 (6.49 q/ha), HUL 57 (6.10 q/ha) and WBL 77 (5.68 q/ha) with 127, 118 and 130 days to maturity. Linear relationship of...
Evaluation of extra early lentil varieties in rice-fallow areas of West Bengal
The Pharma Innovation Journal, 2019
A field experiment was conducted to assess seven lentil varieties in terms of phenology, yield attributing characters and yield in randomized block design at district seed farm, AB block, BCKV, West Bengal, during rabi seasons of 2014-15 and 2015-16. Result revealed that among the seven varieties evaluated, L4710 was the earliest maturing one, whereas, PL406 was late maturing type and took 110 days. Regarding the yield attributing characters, the no. of primary branches per plant was highest in both KLS 218(2.85) and IPL 534(2.85). Lack of similarity among lentil varieties was noticed based on seed index also. RKL-604-01 is bold seeded type (3.15g), followed by IPL 534 (2.85g). IPL 534 produced highest yield (1559 kg ha-1) with an advantage of 9.40% to 51.25% over other varieties. In terms of pooled data of two years, L4710 was also recorded a good yield (1425kg ha-1) with maximum number of pods per plant (80.9). With the changing climate scenario, variety L4710 and IPL 534 were found to be promising in terms of phenology, yield attributing character, and yield after long duration rice.

Frontline demonstrations were carried out at 859 farmers' field of four districts covering an area of 238.68 ha in 89 villages of Garo Hill districts, Meghalaya during rabi season, 2013-2016 to study the effect of different cultivars and tillage methods on growth, yield and economics of lentil in rice fallow areas. The cultivars of lentil evaluated were HUL 57, WBL 77, Patnai (local) and tillage methods were conventional, relay and zero tillage. Results revealed that the higher significant values were recorded under conventional sowing incorporating bio fertilizer (Rhizobium) in terms of seed yield (8.62 q/ha) and net return (Rs. 28,103/ ha). However, as per benefit cost ratio, highest values were found in relay cropping (2.80) in comparison to other sowing methods. Significantly lower seed yield was recorded in zero tillage than conventional and relay cultivation methods. Among the varieties tested, WBL77 produced the highest seed yield of 7.28 q/ ha which showed 45.30 per cent increase over the local variety, a net return of Rs.26643/ha and a benefit cost ratio of 2.76. The lowest production and net returns were found in zero tillage cultivation method.
Evaluation of Lentil Genotypes in Different Sowing Windows in the New Alluvial Zone of West Bengal
Legume Research- An International Journal, Volume 47 Issue 6: 911-916 (June 2024)
Background: Being a cool season crop, lentil is very sensitive to temperature during its growth stages. It is found that delayed harvest of the preceding crop which is most frequently rice causes the majority of the country's lentil sowings to be postponed in India. As a result, the late-sown crop suffers during the seed-filling stage due to the rising high temperatures in most of its cultivated areas and results in lower yield. Therefore, there is a need to work out the optimum sowing time for realizing maximum yield potential as well as the selection of varieties suitable for normal as well as late sown condition of the crop. Methods: A field experiment was carried out in the new alluvial zone of West Bengal at the District Seed Farm of BCKV, Kalyani during the two subsequent rabi seasons (November-March) of 2019-2020 and 2020-2021 to examine the difference in yield between normal and late seeding conditions for various lentil cultivars. There were a total of ten genotypes evaluated, with each one being planted at one of two different times (15 th Nov and 30 th Nov). Result: The experimental findings revealed that lentil sown on 15 th November recorded higher seed yield (2.34 t ha-1) compared to 30 th November sown crop (1.63 t ha-1). Among the ten varieties, unreleased genotype C 23 E 21 recorded the highest seed yield (2.25 t ha-1), followed by ILL 10802 (2.18 t ha-1). According to the results of this study, delaying the sowing window from the middle to the end of November can reduce yields by as much as 27.77%. Therefore, it is prudent to encourage the lentil farmers in the new alluvial zone region of West Bengal to sow their crops no later than the 15 th of November of the Rabi season, to prevent a drop in production.
Performance of BARI released lentil varieties in charland ecosystem under Kurigram district
Journal of Bioscience and Agriculture Research, 2017
The on-farm trial of BARI released lentil varieties was conducted at the MLT site, Ulipur, Kurigram during Rabi season of 2013-14 and 2014-15 in the Lentil-Sesame-Fallow cropping pattern in the Charland. The experiment was laid out in a randomized complete block design with six dispersed replications. Four variety viz., BARI Masur-4, BARI Masur-5, BARI Masur-6 and BARI Masur-7 with local cultivar were compared for this purpose. Among the tested varieties, BARI Masur-7 gave the highest yield in both year (1.43 and 1.40 t/ha) which differed significantly from other varieties and the lowest yield was recorded from local (0.860 and 0.834 t/ha). The highest gross return (Tk. 114240 and 112000 ha-1) and gross margin (Tk. 81940 and 77160 ha-1) were obtained from BARI Masur-7 in two consecutive Rabi season. The lowest gross return (Tk. 68800 and 66720 ha-1) and gross margin (Tk. 36500 and 31880 ha-1) were obtained from the local cultivar. The lentil production was profitable to the farmers in the study areas with BARI released lentil varieties.
Growth, Yield and Yield Components of Lentil as Influenced by Irrigation and Weeding Regime
Journal of Environmental Science and Natural Resources, 2015
The experiment was carried out to study the effect of irrigation and weeding regime on growth, yield and yield contributing characters of lentil. The experiment was laid out in a split-split plot design with three replications. Four levels of irrigation viz. control or no irrigation (I 0 ), one irrigation (I 1 ), two irrigation (I 2 ) and three irrigations (I 3 ) and three weeding regime viz. control weeding (W 0 ), one weeding (W 1 ) and two weedings (W 2 ) were used. Irrigation had significant effect on all the growth, yield and yield contributing characters. The highest TDM , CGR and all the yield contributing characters like plant height, number of branches plant -1 , number of pods plant -1 , number of effective pods plant -1 , number of seeds plant -1 , number of filled seeds plant -1 , 1000-seed weight and stover yield were obtained from three irrigations (I 3 ) and consequently it produced the highest seed yield. Effect of weeding regime was significant in respect of on the growth, yield and yield contributing characters. All the yield contributing characters except non-effective pods plant -1 were found the best when two weedings were done and as a result it produced the highest seed yield. With some exception two weedings showed highest values of TDM, CGR and other growth character. Finally the results suggest that three irrigations with two weedings are better practices to get higher growth and yield of lentil.
To improve land productivity, food and nutritional security in this region, rice-fallow areas which are about 11 million hectare area in eastern India, should be brought under cultivation with pulse crops that can survive in residual moisture. Present study was aimed at to identify suitable lentil varieties which can perform better under varying field conditions and management practices prevalent in the region. Five lentil varieties and two tillage practices were evaluated under puddled and unpuddled transplanted rice field. Lentil variety Pusa Vaibhav performed equally well with zero as well as conventional tillage under unpuddled transplanted rice, whereas Mallika performed well under zero tillage in sequence with puddle transplanted rice. Both the varieties being of medium duration are suitable for rice-fallow areas of eastern region of India. Adopting conventional tillage practices is beneficial for lentil cultivation if it is to be grown in the puddle transplanted (PT) rice field, where as in case of preceding unpuddle transplanted (UPT) system zero tillage practices is advisable.
Background: Lentil is the major cultivated pulse crop in the state of West Bengal in terms of total area coverage under cultivation. Selection of high yielding and better quality genotype is the prime vital matter to increase productivity. Investigation and a better understanding of the variability existing in a population base of the crop are pivotal to crop improvement so that the plant breeders can exploit it. Methods: The current study has been carried out at the experimental farm of the University of Calcutta during 2016-2017 in a plot designed with the randomized block design. It was carried out to estimate the magnitude of genetic variability, heritability and genetic advance of fifty-four lentil germplasms. Result: Moderate to high heritability, GCV, PCV, GA and GA % of mean was obtained by days to1 st flowering, days to 50% flowering, pods per plant and harvest index. The genotypic and phenotypic association of seed yield was significantly positive with traits like plant height, pods/plant, 100 seed weight and harvest index. Characters like days to 50% flowering, plant height, primary branches per plant, pods/plant, pod length, 100 seed weight and harvest index shows a positive direct effect on seed yield in path analysis suggesting select for such traits while exercising selection for seed yield per plant in lentil.
