Drought stress is a serious stress leading to limited crop production in present climate changing era. The present investigation was carried out to evaluate the impact of sodium nitroprusside (nitric oxide donor) and brassinosteroid on mitigating drought stress responses in tomato plants. Experiment with two different water status was conducted with two tomato genotypes to study the mitigating effect of sodium nitroprusside (nitric oxide donor) and brassinosteroid. Drought stress was induced by withholding water for 7 days and normal irrigated plants were used as control. Nitric oxide donor, Sodium nitroprusside (SNP, 50 and 100 µ M) and 24-epibrassinolide (EBL, 1 and 3 µ M), applied singly and in combinations were used as foliar spray on the stressed plants. Drought stress produced various negative impacts in plants in terms of plant height, membrane stability index, malondialdehyde (MDA), proline content, flower drop percent, total soluble solids, polar fruit diameter and number of fruit plant-1. Exogenous foliar application of nitric oxide and brassinosteroid showed the extenuating effect under drought stress by increasing drought tolerance by overcoming negative effects of above mentioned morpho-physiological and biochemical attributes. Exogenous application of 100 µMSNP with 3 µM EBL showed significantly best results followed by 50 µM SNP plus 3 µM, EBL,50 µM SNP plus1 µM EBL and 100 µM SNP plus 1 µM EBL. Our results advocate that exogenous application of SNP and EBL application could significantly improve tolerance in tomato plants under drought stress by the significant changes in morpho-physiology and metabolic processes.
To study the effect of nutrient management through biomanuring on growth, yield and economics of turmeric under organic farming. A field experiment was undertaken on certified organic field during 2020-21 at Centre for Organic Agriculture Research and Training, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra. The experiment was laid out in a randomized block design with nine treatments and three replications. The turmeric variety for experiment was PDKV waigaon. The application of 50% Vermicompost + 50% Neemcake + Biofertilizers shows significantly higher growth attributes such as plant height (87.10cm), number of leaves (13.23), leaf area(46.28dm2) and number of tillers (4.10) at 120DAP. Similarly, significantly higher yield and yield attributes were recorded by application of 50% Vermicompost + 50% Neemcake + Biofertilizers such as number of mother rhizomes(1.87), number of primary rhizomes(6.27) and fresh yield of rhizomes(14.77 tha-1). The higher economics among treatments recorded by application of 50% Vermicompost + 50% Neemcake + Biofertilizers with B:C ratio 3.1. The application of 50% Vermicompost + 50% Neemcake + Biofertilizers resulted in significantly higher productivity of turmeric under organic farming in Vidarbha Region of Maharashtra.
Field experiment were carried out to investigate the effect of organic manures and iron on alkalinity tolerance of wheat under alkali water irrigation in rabi 2019-20 and 2020-21 at SKNAU Jobner Jaipur. As per results irrigation with 10 mmol L-1 RSC water significantly reduced the ionic regulation index for Potassium (IRI-K) (1.145), increased ionic regulation index for sodium (IRI-Na) (4.159), degree of compartmentation at flowering stage (11.20) and higher Na/Ca, Na/K and Na+K/Ca ratios in grain and straw during both the study years and pooled mean in wheat crop. Whereas, significantly maximum Ca/Mg ratio in wheat grain (3.289) and straw (1.798) was observed at 2 mmol L-1 RSC water in irrigation during both the study year and pooled analysis. At flowering stage ionic regulation index for Potassium (IRI-K) increased significantly with application of 5 t ha-1 vermicompost and 15 t ha-1 FYM and 100 kg ha-1 FeSO4.7H2O while, ionic regulation index for sodium (IRI-Na) and degree of compartmentation decrease considerably in both the years and pooled mean and lower Na/Ca, Na/K and Na+K/Ca ratios in grain and straw during both the years and pooled in wheat crop. Whereas, significantly higher Ca/Mg ratio in grain was reported with of 5 t vermicompost ha-1 and 15 t FYM ha-1 and 100 kg FeSO4.7H2O ha-1 application during both the study year and pooled analysis. However, the effect of FYM and vermicompost application was found to be at par with each other.
Ninety three basmati germplasm lines were evaluated during Kharif 2018 so as to identify lines with good quality traits and resistance to Bacterial blight. Data was recorded on various yield and its attributing traits while, seeds of five selected plants of each line were dehulled after harvesting for evaluation of the grain quality traits. Previously reported molecular markers RG136 and Pta248, closely linked to the BB resistance genes, xa13 and Xa21 were employed to confirm the presence of resistance genes. Simultaneously, all the lines were screened for bacterial blight both under natural field and green house conditions using leaf clipping technique and scoring was performed following Standard Evaluation System for Rice. Analysis of variance revealed significant variation for all the traits, while 58 germplasm lines were found to have Xa21 gene with band size of 1300 bp and 57 germplasm lines were found to possess xa13 gene with band size of 800 bp. The germplasm line 1, 2, 3, 6, 9, 10, 13, 15, 17, 19, 20, 21, 23, 27, 30, 32, 33, 34, 37, 38, 40, 43, 44, 47, 48, 49, 50, 51, 52, 54, 56, 57, 58, 60, 62, 66, 71, 72, 75, 77, 80, 83, 85, 89, 90, and 92 possessed two resistance genes i.e. Xa21 and xa13. The germplasm line 5, 8, 11, 18, 24, 26, 29, 35, 45, 55, 59, 61, 64, 70, 73, 76, 78, 79, 81, 82, 84, 86, 87, Ranbir basmati, Jammu Basmati 129, Pusa Basmati 1121, Basmati 564, Saanwal basmati and Basmati 370 lack either of the resistance genes i.e. Xa21 or xa13. When the resistance of the germplasm lines was considered along with the yield performance, GP2, GP43 and GP71 proved to be the superior ones interms of resistance to the disease as well as yielding ability. GP2 and GP71 also possessed good basmati quality parameters and can be used as varieties after testing in yield trails.GP1, GP2, GP3, GP6, GP9, GP10, GP13, GP19, GP21, GP23, GP37, GP43, GP47, GP48, GP50, GP51, GP52, GP56, GP58, GP62 and GP71 can serve as potential donor for the transfer of bacterial blight resistance genes into elite basmati varieties.
Field experiment was conducted during rabi season to determine the “Response of foliar application of micronutrients and PGR on productivity and profitability of tomato (Solanum lycopersicum Mill.)” was carried out during 2018-19 and 2019-20 at Vegetable Research Farm of C. S. Azad University of Agriculture & Technology Kanpur U.P (208002) India. Experiment was laid out in a randomized block design (RBD) with eleven treatments replicated three times consist of two levels of each micronutrients and growth regulators with control i.e.T0: Control, T1: GA3 50ppm, T2: GA3 100ppm, T3: NAA 50ppm, T4: NAA 100ppm, T5: ZnSO4 0.5%, T6: ZnSO4 1%, T7: Boric acid 50ppm, T8: Boric acid 100ppm, T9: FeSO4 100ppm and T10: FeSO4 150ppm on Vegetable Crops. Azad-T6 variety of tomato was transplanted at a spacing of 60 cm × 45 cm. Results of the experiment revealed that the Application of GA3 100ppm concentration showed significantly increased growth, flowering, yield, fruit quality and economic return of tomato. Therefore, the concentration of PGR and micronutrients may be recommended to exploit the better eco-friendly economic yield of tomato.
