A belt conveyor type dryer was developed to reduce the moisture content of dehulled tamarind fruit to an optimized level for deseeding and hence reduce the wastage of fruits. The dehulled tamarind fruit was dried under three different temperatures (50, 60, & 70oC) with the combination of three different airflow rates (0.5, 1.0 & 1.5 m/s) and three different feed rates (5, 7.5 & 10 kg/h). The selected variables were optimized using statistical analysis to develop the prototype dryer. The optimized temperature, airflow rate and feed rate were 60oC, 1.5 m/s and 5 kg/h, respectively. The drying models were used for analyzing the drying kinetics of dehulled tamarind fruit under different temperature conditions. The highest coefficient of determination of 0.99 and reduced Chi square of 0.0001 favoring the optimized drying condition was obtained for the Midilli model. The color change of dehulled tamarind fruit during drying were measured by Hunter color meter. The most preferable color was obtained at 60oC drying temperature and the corresponding L*, a* and b* values were 49.5 ± 2.6, 2.9 ± 1.1 and 11.5 ±1.4, respectively.

Jackfruit (Artocarpus heterophyllus) is a large species in Moraceae family which is commonly found in Mekong delta of Vietnam. The demand of jackfruit products is presently increased for domestic consumption and processed export purposes. Nevertheless, breeding materials of jackfruit are insufficient since the identification of breeding material is mainly based on morphological characteristics. The effective applications of molecular markers to evaluate the genetic diversity of plants for enhancing the accuracy of plant breeding have been reported in different plants. In this study, two molecular markers namely RAPD and ISSR were applied to investigate the genetic variation of 20 jackfruit accessions collected in Mekong delta provinces in Southern Vietnam. The obtained results showed that both RAPD and ISSR markers produced a high number of polymorphic bands ranging from 8 to 12 and 3 to 8 bands, respectively. Based on the PIC values, the primers used by both markers are highly informative which are 0.69 or higher. The similarity coefficients are variable, ranged from 0.40-0.80 and from 0.41 to 0.81 for RAPD and ISSR, respectively. The phylogenetic analysis showed that collected jackfruit accessions were classed in different clusters with coefficient index varying from 0.52 to 0.87 suggesting the large variation in genetic composition of the jackfruit population in Vietnam. The findings could be potential to employ in future classification, conservation and development of this plant in the region.

Influence of Cutting Intervals and Nitrogen Levels on Growth and Yield of Dual Purpose Wheat under Mid Hill Conditions of J&K, India

Paper ID- AMA-01-09-2021-10670

In hilly agro-ecologies of north-western Himalayan region, there is always a scarcity of quality green fodder during extreme winter months. Due to this reason farmers are unable to feed their livestock properly and often the livestock remained under nourished, becomes weak and prone to various diseases. Wheat being a major winter season cereal crop can be grown for dual purpose providing grain as well as high quality forage for livestock from same patch of land. It is a valuable source of high quality forage, rich in protein, energy, nutrients and low in fiber. An experiment was conducted during the rabi season of 2017-18 and 2018-2019 at Rajouri, Jammu and Kashmir, to study the effect of cutting intervals and nitrogen levels on growth and yield of dual purpose wheat. Among the cutting intervals, the uncut wheat gave significantly higher growth parameters, yield attributes, grain yield and straw yield than other cutting treatments. Whereas, the cutting of wheat for green forage at 85 DAS gave significantly higher green forage yield over other cutting intervals but the highest grain equivalent yield was recorded when cutting of wheat for green forage was done at 65 DAS (5.54 t/ha.) which was closely followed by the cutting interval of 75 DAS (5.41 t/ha) which recorded maximum, net returns (70.1 x103 ₹ / ha) and benefit cost ratio (2.20). Among nitrogen levels, application of nitrogen @ 120 kg/ha recorded significantly higher growth, yield attributes and yield of wheat. Partial factor productivity, agronomic efficiency, net returns and benefit: cost ratio of wheat except partial factor productivity which was recorded maximum with application of nitrogen @ 60 kg/ha.

Population dynamics of Leiognathus splendens (Cuvier, 1829) from Myeik coastal waters, Myanmar

Paper ID- AMA-31-08-2021-10667

Growth and mortality parameters, exploitation rates and recruitment patterns were estimated from the monthly length-frequency samples of Leiognathus splendens collected from the catches of trawl fisheries in Myeik coastal waters, Myanmar. The estimated values of von Bertalanffy growth parameters: L∞, K and t0 were 14.7cm, 1.3 year-1 and -0.008. L. splendens attains total lengths of 7.11, 10.74, 12.63, 13.62 and 14.7cm at the end of 0.5, 1, 1.5, 2 and 2.5 years, respectively. Longevity calculated from Pauly’s equation was estimated as 2.29 years. The estimated mortality rates Z, M and F were 4.86, 2.54 and 2.32 year-1, respectively. The resultant exploitation rate was 0.5. Recruitment was noted to be year- round and bimodal.

The selection method against drought stress using PEG in the vegetative phase was used to simulate maize tolerance to drought stress in the vegetative phase. The main objective of this research was to determine the response of maize genotypes that were tolerant and sensitive to drought stress in the vegetative phase. The research was conducted at the Greenhouse, Agrotechnology Study Program, Trunojoyo University, Madura – Indonesia. The planting materials consisted of twenty maize genotypes, consisting of fifteen Madura-Indonesian local maize genotypes, and five national-Indonesian varieties (Srikandi Kuning, Sukmaraga, BISI-2, PIONEER 21, and Anoman). The research design used a factorial randomized complete block design. The first factor was twenty maize genotypes, while the second factor was the giving of PEG- 6000 solution with a concentration of 10% which was equivalent to -0.19 Mpa. The results of the vegetative phase selection of drought stress- tolerant maize genotypes revealed that G3, G4, G8, and G11 were tolerant genotypes, whereas G1, G2, G5, G6, G7, G9, G10, G12, G13, G14, and G15 were drought-sensitive genotypes.
