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.

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...
Improving crop output requires optimizing seed rate, especially in areas with diverse agroclimatic conditions. This study looks at how varying seed rates affect the production of several cultivars of lentils (Lens culinaris) in Quetta, a semi-arid area with variable weather and little precipitation. The best planting density for each of the four lentil cultivars was tested using varying seed rates. Two growing seasons were used for the experiment in order to account for environmental variability. Based on seed rates, the results showed significant variation in yield, with both under-and overseeding resulting in insufficient plant growth and production losses. Varying seed densities required different seed rates to maximize output, highlighting the need to tailor planting density to the unique genetic characteristics of each variety of lentil. The findings suggest that lentil productivity can be significantly increased by adjusting seed rates according to local climatic conditions and varietal kinds. This research provides valuable data for lentil growers in Quetta and similar regions, along with actionable recommendations for increasing yields through optimal seeding rates. To evaluate the long-term effects of varying seed rates on soil health and overall agricultural sustainability in semi-arid settings, more research is suggested.
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.

A field experiment was conducted during rabi season of 2013-14 and 2014-15 at Agriculture Farm of Palli Siksha Bhavana (Institute of Agriculture), Visva-Bharati, Sriniketan, West Bengal to find out the varietal performance of different promising entries of lentil on growth attributes and yield. Tendifferent varieties viz. Subrata, Asha, Ranjan, HUL 57, BM 6, BM 7, PL 406, KLS 218, Moitree and PL 6 was studied in a randomized block design (RBD), replicated thrice. Different growth and yield attributes were measured in the experiment to find out the suitable variety of lentil for the red and lateritic soil zone of West Bengal. The lentil variety PL-406 showed maximum growth potentiality among the other varieties just followed by another long duration lentil variety KLS-218. The lentil variety PL-406 showed maximum growth potentiality among the other varieties just followed by another long duration variety KLS 218. Highest grain yield was obtained from the variety Ranjan (789 kg ha-1) followed by the variety PL 406 (785 kg ha-1) and KLS 218 (783 kg ha-1) respectively. From the result of the present experiment, it can be concluded that the variety PL 406 gave maximum vegetative growth, whereas the variety Ranjan produce maximum yield and found most potential variety among other lentil varieties under red and lateritic soil of West Bengal.

To study the seed yield, yield components and some main crop traits in 25lentil genotypes, including 23Ardabil local genotypes and 2control genotypes, a research was conducted at Ardabil Islamic Azad University Agricultural Research Stations at Hasan Baruq and Alaruq, during 2010 and 2011, respectively. In each year, two rain fed and irrigated planting experiments were carried out in randomized complete block design (RCBD). According to the combined analysis of variance results between two environments, there was a significant difference found between seeds large diameter. Also, there was a significant difference found between rain fed and irrigated conditions in seed large diameter and seed yield. There was a significant difference found between studied genotypes on number of leaflet and seed yield in plot unit. The genotype × environment interaction was significant on number of filled pods, total number of pods, number of seeds per plant, seed weight per plant, seed large diameter, seed weight and seed yield. Genotypes No. 7 and No. 11had the highest yield in Hasan Baruq and Alaruq stations, respectively.
Genetic Variability in Yield Attributes of Lentil Genotypes under New Alluvial Zone
Current Journal of Applied Science and Technology, 2018
The experiment was conducted under new alluvial zone in West Bengal to evaluate the heritability for yield components and its impact on seed yield in 10 diverse genotypes of Lentil. In consideration of two successive years, the significant hierarchy was shown in 2 nd year for the characters except in days to 1 st flowering. ASHA and WBL-77 were effective for earliness in maturity among all genotypes. The maximum growth rate was observed in K-75 and KLS-218. The different varieties showed high significant variations in 1000 seed weight with top most effect in PRE-COZ. Interaction of two factors i.e variety (V) x year (Y) showed a significant variation in plant height and pod number, as well as seed yield through it, was non-significant in days to 1 st flowering, maturity and seed weight. Results indicated that the genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) showed the genetic influence of these morphological traits. The heritability (h 2 %) in addition to high genetic advance as percentage of mean was >20% for most of the characters indicated the influence of additive gene. In observation of the correlation matrix, the total parameters maintained two distinct groups considering plant growth parameters and direct yield attributing traits. A negative or non-significant relationship was followed in between these groups of growth and yield traits though the strong positive correlation was followed within diverse traits of each group.

Lentil is a versatile and profitable pulse crop with high nutritional food and feed values. The objectives of the study were to determine suitable locations for high yield and quality in terms of production and/or breeding, and to identify promising genotypes. For this reason, five lentil genotypes were evaluated in a multi-location network consisting of ten diverse sites for two consecutive growing seasons, for seed yield (SY), other agronomic traits, crude protein (CP), cooking time (CT) and crude protein yield (CPY). A significant diversification and specialization of the locations was identified with regards to SY, CP, CT and CPY. Different locations showed optimal values for each trait. Locations E4 and E3, followed by E10, were “ideal” for SY; locations E1, E3 and E7 were ideal for high CP; and the “ideal” locations for CT were E3 and E5, followed by E2. Therefore, the scope of the cultivation determined the optimum locations for lentil cultivation. The GGE-biplot analysis rev...

Character association in forty eight genotypes of lentil was studied for nine different agro-morphological characters in normal and late sown conditions. Normal sown condition was taken into consideration as optimum environment and late sown as heat stressed environment. The correlation study revealed consistent positive significant character association (at genotypic and phenotypic levels) of pods per plant with seed yield per plant in both sowing conditions. So this character may be considered for yield improvement. From path coefficient analysis study it was revealed that pods per plant showed consistently positive direct effect on seed yield/plant for both sowing conditions.
