Cytological observations in colchicine induced hexaploids and their triploids of cross between Gossypium hirsutum [2n = 4x = 52, (AD1)] and Gossypium armourianum [2n = 2x = 26, D2-1]
Two interspecific hexaploid [2n=6x=78, 2(AD1)D2-1] fertile hybrids between two varieties of cultivated tetraploid species G. hirsutum [2n=4x=52, (AD1)] viz., MCU 5 and TCH 1609 and wild diploid species G. armourianum [2n=2x=26, D2-1] were synthesized by doubling the chromosome number of their respective F1 sterile triploid [2n=3x=39, (AD1)D2-1] hybrids using aqueous colchicine solution. Morphological and cytogenetic analysis confirmed the true nature of triploid and its hexaploid hybrids. The F1 triploid plants were intermediate in morphological characters and they were highly pollen sterile as well as self sterile. A maximum of 13 bivalents per PMC was recorded in G. hirsutum var. MCU 5 X G. armourianum triploid [2n=3x=39, (AD1)D2-1] but 10 I + 13 II +1 III was the most frequent meiotic configuration. In the triploid of G. hirsutum var. TCH 1609 X G. armourianum [2n = 3x = 39, (AD1)D2-1], maximum of 13 bivalents was recorded with an average of 11.08 bivalents, but 10 I + 10 II + 3 III and 13 I + 13 II were the most frequent meiotic configuration. The hexaploids [2n=6x=78, 2(AD1)D2-1] showed the expected features of the colchiploidised plants such as large sized flowers than triploids, increased pollen grain size, fertile pollen grains, boll and seed set with fibres as compared to the F1 sterile triploid plants. The hexaploid G. hirsutum var. MCU 5 X G. armourianum [2n=6x=78, 2 (AD1)D2-1] recorded maximum of 32 bivalents per PMC with most frequent meiotic configuration of 3 I + 25 II + 3 III + 4 IV. The maximum of 29 bivalents with an average of 24.96 bivalents per PMC was recorded in G. hirsutum var. TCH 1609 X G. armourianum hexaploid [2n=6x=78, 2 (AD1)D2-1], but 3 I + 28 II + 5 III + 1 IV was the most frequent meiotic configuration. The morphological and meiotic behavior of these hexaploid hybrids provided valuable information for their practical utilization in a cotton breeding programme.
Sustainable yield management of farm-grown teak in the Cauvery delta zone
A natural Teak resource is available only in few tropical and sub-tropical countries like India, Myanmar, Thailand etc. India is the leading exporter of teak resources in early decades, but presently the country is becoming the major net importer of teak resources in order to meet their requirements. Based on the constrains, the present study was conducted in farmlands under Cauvery Delta Zone (CDZ) of Tamil Nadu to analyze the available teak resources and their influence on growth and volume production. The growth and volume production of teak among the farm grown teak in different age class were recorded in cauvery delta agroclimatic zone of Tamil Nadu. In this study, we evaluate the use of a linear program (LP) to achieve sustainable yield management in the Cauvery Delta Zone specifically for teak trees that are between 12 and 13 years old age class attaining maximum yield 56. 16 tonnes and DBH (0.6477 m). Hence, it is concluded that under farmland condition, Cauvery delta zone is more superior zone for teak plantation due to the influence of optimum climatic and edaphic factors. Through the use of the simultaneous equation, a sustainable height and DBH are calculated, and the accuracy of the prediction is enhanced with increasing stand age. The final step is determining which model, the linear program or the SPSS software-ARIMA model, provides the best fitting results.
Development of Highly Nutritious Energy Bar Using Chia Seeds and Analyze its Nutritional and Nutraceutical Properties
Salvia hispanica seed often is sold under its common name "chia" as well as several trademarked names. The seeds have a relatively high content of protein of high biological value. Chia seed energy bar was made in three different variations. The energy bar was prepared using 30%, 40% and 60% inclusion of chia seeds as value added product development. In variation I, the high mean value was obtained for flavor such as 8.45 than other sensory attributes. In chia energy bar variation 2, the high mean value was obtained to overall acceptability as 8.35 mean values & In variation 3, the high mean value was obtained for to overall acceptability as 8.35 mean value in sensory evaluation. Nutritive value of carbohydrate, protein, fat, fibre, iron, calcium were present in chia energy bar. Chia seeds are excellent source of omega 3 fatty acids. In this research paper value added products from chia seeds to improve nutritional status of our society.
Assessment of organic management and farmer’s practices in ginger cultivation
A field experiment was conducted in three different location of Tangabari village of Chirang district, Assam, India in 2022 to assess farmers’ practices of ginger cultivation vis-à-vis it’s organic management practices using farm yard manure (FYM), Vermicpompost (VC), Biofertilizer (BF: PSB and Azospirrillum). From the experiment it was observed that the plants attained maximum height of 84.93 cm in the plots treated with the concoction of FYM, VC and BF followed by 84.77 cm in the plots treated with VC only. Similarly, the same treatment also resulted in the highest number of leaves per plant (9.43) and number of tillers per clump (15.5) while the maximum number of fingers (15.2) per rhizome was observed in the plots treated with vermicompost. For yield, the concoction of FYM, VC and BF was found to be most effective producing 28.01 tonnes of rhizome per hectare with a BC ratio of 3.88. Throughout the experiment, farmers practice was found to be inferior to organic management practices adopted for ginger.
UPSCALING OF COWPEA (Vigna unguiculata L.) VARIETIES FOR GRAIN YIELD AND PROFITABILITY THROUGH ON FARM TRIAL
Cowpea is one of the important food legume crops belonging to the Fabaceae family. Farmers lack of awareness about the latest cowpea varieties suitable for rainfed situations; therefore, an attempt was made to assess suitable varieties for enhancing yield and productivity under on farm trial. The present investigation was conducted in three villages of Virudhunagar district to assess the suitable variety of cowpea for rainfed conditions. Five farmers’ fields were randomly selected and two high yielding improved varieties of cowpea (VBN 3 and DC 15) were sown along with one check variety (CO (CP) 7). The trial was conducted with five replications. During the course of study, observations like plant height (cm), days to 50 % flowering, grain yield (q/ha) were recorded. Among the varieties assessed, VBN 3 variety recorded the plant height (68.9 cm), days to 50 % flowering (53 days), maximum grain yield of 11 q/ha with high net return (Rs.49500) and Benefit-cost ratio (1:2.20) followed by DC 15 grain yield of 10 q/ ha. Hence, it was concluded that the VBN 3 variety of cowpea proved superior followed by DC 15 under the rainfed condition.
