Sugarcane is cultivated in an area of 4.5 million ha with an average productivity of 79 t/ha. Sustainable Sugarcane Initiative (SSI) is one of the advanced methods of sugarcane cultivation technique that involves, use of less input like seed sett, water, land, labour and optimum utilization of fertilizers to achieve maximum yield. Removal of mother shoot is one of the main techniques of SSI to get even number of tillers, increase the number of tillers and millable canes per plant. Conventional tool like secateurs, knifes and sickles being used among the sugarcane growers, even after experiencing the less efficiency of tool. In addition, more drudgery is involved, because the agricultural labourers need to bend down and hold the stem to remove the mother shoots in each sugarcane plant. Chances of getting injury to the hands and eyes are more during this operation. Hence, a hand operated tool for removing the mother shoot of sugarcane plants was developed and evaluated in sugarcane crop during 30 to 35 days after transplanting. The tool is manual operated and can be operated in standing posture for a long time. Women labourers can also cuts sugarcane mother shoots easily due to low weight (1.6 kg) of the tool. The tool saves cost and time by 47 per cent and 44 per cent, respectively compared to cutting of mother shoots with sickle. One could cut 1200 shoots/h with the tool. The tool costs Rs. 800/- and cost of operation is Rs.465 per hectare","PeriodicalId":18154,"journal":{"name":"Madras Agricultural Journal","volume":"212 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76157273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The crop geometry of moringa highly influenced the leaf yield. An experiment has been conducted in 2021 at Western block farm, Horticultural College and Research Institute, Periyakulam under irrigated conditions to study the effect of crop geometries and harvesting heights on leaf yield of moringa var. PKM 1. Treatments combination consists of four crop geometries viz., 1.50m x 0.25m (S1), 1.50m x 0.50m (S2), 1.50m x 0.25m x 0.25m (S3), 1.50m x 0.50m x 0.50m (S4) and three harvesting heights of 30 cm (T1), 45 cm (T2) and 60 cm (T3). The study laid out in a Split plot design with three replications. The growth parameters such as plant height and a number of compound leaves were significantly higher in the closer spacing of 1.50m x 0.25m x 0.25m whereas a number of primary branches and stem girth were significantly higher in the wider spacing of 1.50 m x 0.50 m. Harvesting heights have no influence on the growth parameters. Moringa raised under spacing 1.50 m x 0.25 m x 0.25 m in conjunction with harvesting height of 30 cm (S3T1) significantly influenced the yield parameters such as compound leaf yield, fresh leaflets weight, dry leaf weight, and found maximum.","PeriodicalId":18154,"journal":{"name":"Madras Agricultural Journal","volume":"832 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91461286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data of plant height, number of leaves, single leaf area, single-leaf weight, leaf mass area, leaf area index (LAI), leaf angle, yield, and biomass were subjected to analysis of variance that showed significant differences among the genotypes. The genetic variability among the genotypes and the co-efficient of variation was high for all the traits analyzed except leaf mass area with 17.47%. A high coefficient of variation was recorded in the number of leaves and grain yield per plant with 42.68 and 38.55%, respectively. Frequency distribution for these traits showed that the genotypes in the category of 4 to 12 LAI fall in the category of 30 to 90g of grain yield. Most of the traits showed symmetrical skewness and mesokurtic distribution.Besides, the correlation coefficient of LAI had a significantly positive correlation with leaf mass per area, leaf numbers, and biomass, indicating the importance of the leaf area index in determining yield and biomass. Furthermore,single leaf area hada significant positive association with leaf angle, single-leaf weight, and plant heightand a negative correlation with leaf numbers and leaf mass area.The results revealed the highest genetic variability and association between two or more variables among this rice germplasm.

Dhaincha, is an ideal green manure crop used for the improvement of soil fertility and it also reclaims problematic soils. To screen out the Dhaincha genotypes based on the seedling biomass, a pot culture experiment was carried out at the Department of Plant Breeding and Genetics, Anbil Dharmalingam Agricultural College and Research Institute, Tiruchirappalli, with four different genotypes namely Vellore local, Villupuram local, Sivagangai local and Pant dhaincha. Root length, shoot length, fresh and dry weight of root & shoot, base diameter, and biomass per plant were recorded at ten day of intervals till sixty days after sowing. All the parameters showed significant variation and increased steadily every ten days after sowing. Sivagangai local recorded the highest growth parameters than the other genotypes. The highest biomass yield was observed in Villupuram local (0.029 g/plant) at 10 DAS, indicating that it produces more biomass during the early stages of growth. At 60 DAS, Vellore local recorded a high total biomass yield (2.3 g/plant), followed by Villupuram local (1.2 g/plant), Sivagangai local (1.08 g/ plant), and Pant dhaincha (0.9 g/ plant). Based on the growth parameters and High biomass yield per plant Sivagangai local and Vellore local can be selected for further crossing programmes.","PeriodicalId":18154,"journal":{"name":"Madras Agricultural Journal","volume":"303 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76439853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Probiotic lactobacilli are the potential microbes to reduce unavoidable pesticide absorption besides their ability to degrade pesticides in humans and wildlife. The present study aimed to evaluate the strains Lactobacillus plantarum Pb3, Lactobacillus acidophilus Pc1 and Lactobacillus lactis Pt4 for their antioxidant ability and tolerance to simulated gastric and intestinal juice to understand their effects against oxidative damage induced by the pesticides chlorpyriphos, imidacloprid and chlorantraniliprole. Among the three strains, L. plantarum Pb3 exhibited the highest antioxidant ability and tolerance to simulated gastric and intestinal juices, followed by L. acidophilus Pc1 and L. lactis Pt4. Intact cells possessed higher activity than cell-free extracts and cellfree supernatant. The lipid peroxidation inhibition ability of intact cells of L. plantarum Pb3 in the presence of chlorpyriphos, imidacloprid and chlorantraniliprole was 58.12%, 50.75% and 48.88% respectively, and it was 46.19% in the absence of pesticides.

Under simulated gastric and intestinal juices, a 70 to 75% survival rate was recorded in L. plantarum Pb3.
