    Abstract: Chickpea (Cicer arietinum L.) is one of the most important legume crop in the world and mostly cultivated during the cool winter season (Nov-Feb) in India. In recent, chickpea production and yield drastically reduced in India due to abnormal monsoonal rainfall distribution and soil conditions has been changed due to several improper management of fields and especially soil borne disease like wilt. On regularly, Fusarium wilt incidence occurring early sown cultivars. The wilt incidence occurred during 18-35 days on ramification stage, so the plant loses their reproduction stage and yield also retarded. Several strategies were applied in management of wilt but the pathogen (F. oxysporum f. sp. ciceris) recovered their virulence ability and broke the host resistance. Continuously screened the selection of resistant lines, combined application of biocontrol treatments, plant defense activators and fungicides recorded the highest yield with least incidence of wilt.

    Abstract: Rice is a water-loving crop and traditionally sown in the nursery and then transplanted to the puddled and waterlogged main field. Owing to climate change, water scarcity and labour shortage problems, rice is now cultivated in the dry direct seeded method. Owing to potential of hybrid rice in increasing both rice production and productivity, many countries are focusing on exploiting the benefits of this technology. To break the yield plateau in rice cultivation, Thermosensitive Genetic Male Sterile (TGMS) hybrids were found to be very effective. In the present study, 41 TGMS hybrids and 9 checks were evaluated for their stability and adaptability by dry direct seeded method in four locations viz., E1 - Allahabad, E2 - Lucknow, E3 - Dhamtari and E4 - Raipur. The TGMS hybrid G44 was predicted as an ideal hybrid by the GGE stability model that possessed high grain yield and stable performance over environments. It was followed by hybrids viz., G10, G14, G34, G11, G20 and G47 that had a stable performance with high yield. Hence, these TGMS hybrids were identified as high and stable yielders across environments and suitable for dry direct seeded rice ecosystems. Among the environments, E1 (Allahabad) and E4 (Raipur) were considered favourable environments as they possessed the highest discriminating power. The hybrids identified in the study can be utilized for breaking the yield barriers in rice and can be recommended for dry direct seeding in marginal and rainfed areas.

    Abstract: Background: The study on the effect of varied plant density with different pruning levels on growth and flower yield in Jasminum sambac (L.) was carried out at the Department of Floriculture and Landscape Architecture, TNAU, Coimbatore during 2021-2022. Methods: The experiment was laid out in Factorial Randomized Block Design (FRBD) with eight treatment combinations and replicated thrice. The treatments comprised of T1 (D1P1)- Control = One plant pit-1 + one pruning year-1, T2 (D1P2) = One plant pit-1 + two prunings year-1, T3 (D2P1) = Two plants pit-1 + one pruning year-1, T4 (D2P2) = Two plants pit-1 + two prunings year-1, T5 (D3P1) = Three plants pit-1 + one pruning year-1, T6 (D3P2) = Three plants pit-1 + two prunings year-1, T7 (D4P1) = Four plants pit-1 + one pruning year-1, T8 (D4P2) = Four plants pit-1 + two prunings year-1 respectively. Pruning treatments were imposed on one year after planting of J. sambac (L.) a new clone (nine budded clone) which is prolific and high yielder. Most of the growth and yield parameters were significantly influenced by increased plant densities and pruning levels. Result: Considering the growth and flowering traits in Jasmine, the pooled data indicated that the treatment T6 (D3P2) i.e. three plants pit-1 + two prunings year-1 was found superior for growth and flowering parameters namely plant height (84.47 cm), canopy spread (0.350 m2), number of primary branches plant-1 (16.27), number of secondary branches plant-1 (36.73), number of cymes plant-1 (1989.7), number of nine budded cymes plant-1 (911.0), number of flower buds plant-1 (2875.0), flower yield plant-1 (730.3 g) and flower yield ha-1 (5071.0 kg) whereas, lowest yield (3241.5 kg/ha) was observed in T1 (D1P1) i.e. one plant pit-1 + one pruning year-1. But the parameter on days taken for first harvest of flower buds, number of flower buds cyme-1 and weight of hundred flower buds was found to be non-significant. The results might be due to increased plant density combined with alteration in pruning have enhanced not only speedy plant growth and vast canopy spread but also other yield attributing parameters such as increased number of cymes with nine buds per hectare which in turn might have resulted in higher flower production when compared to conventional planting.

    Abstract: Cotton is a very important crop that consists of traits with different associationship due to genetic and environmental factors. In order to determine the degree of association between seed cotton yield and important traits, a study was done using an RBD experiment with 30 hybrids. Seed cotton yield, plant height, GOT, number of sympodial braches, boll weight, bolls per plant, span length, fineness and strength data were collected and analysed. The experiment was done with 30 F1 hybrids have delivered through Line x Tester mating configuration utilizing six lines and five testers were planted in a Randomized Block Design (RBD) with two replications at the Department of Cotton, TNAU, Coimbatore. Seed cotton yield per plant was found to have significant positive genotypic connection with boll weight (0.5810), number of bolls per plant (0.3867), plant height (0.422) and ginning percent (0.2182) however altogether and contrarily related with consistency proportion at genotypic level. The phenotypic relationship esteems likewise uncovered that seed cotton yield per plant had highly huge and positive phenotypic connection with number of bolls per plant (0.3470) and boll weight (0.4763). Path coefficients were processed to assess the commitment of individual characters to yield in cotton. The way investigation demonstrated high certain immediate impact of number of bolls per plant (0.4743) and fiber strength (0.6880) on seed cotton yield. Micronaire value displayed high sure circuitous impact on seed cotton yield through range length (0.3393), the outcome showed that number of bolls per plant had a high sure relationship with seed cotton yield and sympodial per plant recorded low certain connection with seed cotton yield. It was therefore concluded that selection of high yielding cotton hybrids could emphasize more on lint yield, boll weights, plant height and bolls per plant for better-performing lines. Gin outturn and fibre strength could be used indirectly to improve seed cotton yield through other traits.

    Abstract: Guava is an important edible and economic fruit crop distributed worldwide. It is widely infested with root knot nematode, Meloidogyne enterolobii which plays a vital role in causing economic losses. Several management strategies were performed to enhance the health status of guava and also to reduce root knot nematode infestation. Among the different aspects, application of plant growth regulators on guava plants under nursery conditions against root knot nematode, M. enterolobii was performed. The guava plants were treated with Salicylic acid (100 ppm), Jasmonic acid (100 ppm), and Indole 3-Butyric Acid (1000 ppm) alone and in combination of two and three. The result of this study revealed that IBA at 1,000 ppm alone (T3) and combined application of plant growth regulators viz., (T 4 ) – Salicylic acid (100 ppm) + Jasmonic acid (100 ppm) + Indole 3-Butyric Acid (1,000 ppm) showed reduction in the nematode population and establishment of new roots (compensatory) and tertiary roots. The combined application of PGRs also increased the Plant height, root length, chlorophyll index, photosynthetic rate, transpiration rate, stomatal conductance, and chlorophyll fluorescence. The activity of various enzymes like total phenols, peroxidase, polyphenol oxidase, acid phosphatase, and phenylalanine ammonia lyase were influenced and developed resistance against root knot nematode, M. enterolobii. Under field conditions, application of Pochonia chlamydosporia and Purpureocilium lilacinum reduced the nematode infestation besides increasing the yield attributes of guava plants.

    Abstract: Drought spells and heat stress have become quite common and agricultural production would experience a lag in near future. The combined effect of heat and drought stress is expected to cause negative impact on crop growth. Hence, an experiment was framed to assess the morphological and photosynthetic characters of chilli under combined drought and heat stress. Three different genotypes of chilli viz., K1, TNAU chilli hybrid CO 1, Ramanathapuram gundu were subjected to seven drought and temperature treatments. The experiment was designed in factorial completely randomized design (FCRD) at temperature controlled Open Top Chambers (OTC) and drought stress was gravimetically assesed. The results showed that, morphology and photosynthetic characters were affected irrespective of genotypes. The maximum reduction in plant height and leaf area was observed when plants were grown under 40% pot capacity and temperature of + 5°C from the ambient condition. The study also revealed that, the reduction of gas exchange parameters at 40% PC and A + 5°C with yield reduction of almost 76 per cent irrespective of genotypes. Stress treatments reduced the fruit length, fruit diameter compared to control in all genotypes. Stress Tolerence Index was calculated to study the physiological basis under combined drought and heat stress. The optimum level of stress by STI of 0.501 in 60% PC and A+ 3°C was standardized to study the basic physiological functions of chilli.
