Effect of Organic Manures and Iron on Alkalinity tolerance of Wheat Under Irrigation With Alkali Water
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.
Characterization of Basmati Germplasm for Bacterial Leaf Blight Resistance and Grain Quality traits under North-Western Himalayan region of J&K
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.
Response of foliar application of micronutrients and PGR on productivity and profitability of tomato (Solanum lycopersicum Mill.)
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.
Influence of sugar concentration on quality characteristics of Bael jam during storage
Bael fruit is one of the most nutritious among the various underutilized fruits. The importance of bael fruit lies in its curative properties which makes the tree as one of the most useful medicinal plants of India. The present study was undertaken to investigate the effect of sugar concentration on quality characteristics of bael jam during the various storage months. Fresh fruit of bael had fruit weight, pulp weight, peel weight, pulp: peel, TSS, acidity, reducing sugar, total sugar and ascorbic acid values to the tune of 500 g, 650 g/kg fruit, 350 g/kg fruit, 1.86, 25oBrix, 0.35 per cent, 5.96 per cent, 14.65 per cent and 18 mg/100 g, respectively. Bael jam was prepared as per the treatments in which TSS was raised at 68oBrix by adding sugar and citric acid. The jams prepared from different treatments/sugar concentrations were packed in glass bottles and stored at ambient conditions to observe the effect of sugar concentration on quality and storage for three months at an interval of one month. Total soluble solids, reducing sugar and total sugar decreased significantly, while acidity and ascorbic acid decreased in jam with the advancement of three months storage. No microbial count was found in jam during three months of storage. The acceptability of the product was evaluated in terms of colour, flavour, texture, taste and overall acceptability. The highest mean score for colour (8.66), flavour (8.76), texture (8.68), taste (8.46) and overall acceptability (8.64) found in treatment T3 followed by treatment T2. Jam prepared with treatment T3 was found the most acceptable.
Adaptation: The only way to tackle the issues of Climate Change in Indian Himalayas
Himalayan regions are among the most affected climate change regions in the world. Understanding farmers' awareness and adaptation practices to climate change are necessary to enforce adequate agricultural policies and food security implementation. A total of 200 farmers were interviewed. Maximum respondents (67%) were fully aware of the phenomenon of irregular and erratic rainfall, increase in temperature (68%), reduction in snowfall (61.5%), and changes in water level of waterbodies (57.5%). To adapt to climate change, many respondents (92.5%) adopt drought-tolerant varieties, 91.5 per cent diversify from farming to non-farming activities, and 88 per cent of the farmers store fodder for animals in lean seasons of the year. The awareness level of farmers is significantly related to age, education, size of landholding, Information seeking behaviour, and farmers' socioeconomic status. Adaptation strategies to climate change have significant and positive correlation with landholding size, information-seeking behaviour, and farmers' socioeconomic status. The results may help the government facilitate location-specific research, policy formulation, and implementation in hilly regions for the sustainable future of farmers.
