A study was conducted to analyze the natural flowering behavior of sugarcane clones focusing on identification of the cane characteristics that influence flowering propensity. The findings revealed that clones originating from subtropical agro-climatic zones exhibited the highest flowering propensity and flowered early, whereas those from tropical...

Screening for elite sugarcane genotypes for canopy cover in a rapid and non-destructive way is important to accelerate varietal/clonal selection, and little information is available regarding canopy cover and leaf production, leaf area, biomass production, and cane yield in sugarcane crop. In the present investigation, the digital images of sugarca...

Nursery production of sugarcane settling is gaining importance to replace large quantity of seed cane requirement and the associated cost in conventional method. Sett treatment with nutrients using vacuum-based sett treatment device is effective in delivering nutrients into the setts, and the methodology has already been standardized. However, effi...

The present study was conducted to identify the association of non-destructive rapid estimation of stalk volume by calculation method with water displacement method and to predict the single cane weight by stalk volume. The stalk volume by water displacement method (SVWM) and stalk volume by calculation method (SVCM) were compared for the efficacy...

Rind hardness in sugarcane plays a major role in lodging resistance, and internode borer resistance,screening of sugarcane for rind hardness is essential for reducing yield loss. In order to identify the suitability of soil penetrometer for rapid rind hardness measurement, the rind hardness testing was carried out in two sugarcane clones of differe...

The vast agro-climatic variability of India favours the country to produce all kinds of crops. Although the country has attained self-sufficiency in agricultural production through green revolution efforts, it also created severe sustainability issues on crop, soil and water resources. Intensive cultivation has depleted the soil nutrients and led t...

An experiment was conducted during 2021-22 to evaluate the performance of early maturing high yielding sugarcane varieties at ICAR-Sugarcane Breeding Institute, Coimbatore.

Sugarcane juice (SCJ) is a valuable base product obtained from sugarcane to prepare wide range of products of interest with increased nutritional quality. SCJ contains variety of non sugar impurities which are to be removed prior to preparation of the products including the SCJ beverage. These non sugar components interfere in the stability, colour...

Thirty-one sugarcane genotypes were planted in the experiment and post-emergence application of Halosulfuron Methyl 75% WG and Metribuzin 70% WP was carried out at the rate of 67.5 g and 1000 g a.i. per hectare on 42 days after planting (DAP). Lower leaves of some of the genotypes were found to show injuries on 5 days after spraying (DAS). Phytotox...

Sugarcane being a heavy biomass producer needs enormous quantity of nutrients. Soil has to be replenished with the quantities of nutrients utilized by the crop to maintain the productivity as well as soil quality. Partitioning of nutrients (N, P and K) in the aerial parts of sugarcane genotypes entered in the advanced varietal trial (AVT) during 20...

Liquid jaggery (LJ) is an important intermediate product obtained during the preparation of jaggery from sugarcane juice (SCJ). Unlike the white sugar, LJ is having additional nutritional components which are having wide spectrum of medicinal properties and hence, it is a good nutraceutical. LJ is incorporated in many traditional foods and ayurvedi...

Five improved Erianthus arundinaceus clones were studied for variations in phytoliths present in leaves. Phytoliths were extracted by acid digestion and the morphology was studied by light microscopy. Phytoliths belonging to three classes viz., Eupanicoid, Festucoid and Chloridoid were identified in the samples. Variations in type and shape were ob...

Co 09004(AMRITHA): a new early maturing and high sugar variety for cultivation in peninsular zone.

A long-term field investigation was carried out during 2001 to 2010 at Vittal (Karnataka) in a 22 year old coconut garden under laterite soil to study the impact of inorganic fertilizer substitutions by vermicompost (VC) on productivity and profitability of coconut (Cocos nucifera L.). The treatments, viz. recommended inorganic fertilizer (500 g N,...

Remote sensing provides information on coverage, mapping and classification of land-cover features, such as vegetation, soil, water and forests. Satellite imageries are being used to map areas under different crops and cultivars, and to identify areas with specific characteristics like deficiency symptoms, pest and disease infestation, etc., using...

The treatments, viz. recommended inorganic fertilizer (500 g N,...

Observations were recorded on traits associated with mite infestation related at two stages of button on six different coconut cultivars over three years. Highly significant correlation was found between mite damage score with color or weight of tepal. Step-wise multiple regression of the data analysis showed color of inner tepal as major trait ass...

Coir pith, a ligno-cellulosic biomass formed during extraction of coir fibre from coconut husk, accumulates as a waste material near coir processing factories causing environmental and disposal problems. The feasibility of co-composting coir pith with solid poultry manure was tested with and without lime and rock phosphate amendment. The results re...

A field experiment on evaluation of coconut based high density multi-species cropping system under organic and integrated nutrient management was initiated during 2007 in coconut based cropping system at Central Plantation Crops Research Institute, Kasaragod. Three treatments viz., T1: 2/3rd of recommended NPK fertilizer + recycling biomass (vermic...

The importance of potassium in the Indian agriculture needs no emphasis. It is a key nutrient which is required/removed from the soil in quantities comparable to or more than the nitrogen. Any decline in the soil nutrient pool will have adverse impact on crop productivity. The importance can further be emphasised from the statement of Albrecht (194...
