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...

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...

Technology certainly plays a significant part in the precision agriculture scheme, but understanding the appropriateness of the different forms of technology in response to a management problem is an essential element for successful precision agriculture implementation. Many of the enabling technologies discussed are at varying stages of developmen...

A field experiment was conducted at Coconut Research Station, Aliyarnagar, Tamil Nadu, to study the effect of graded levels of NPK fertilisation on the reproductive characters and yield of coconut hybrid Chandra Sankara (COD x WCT). The three levels of treatments of N (0, 500, 1000 g palm-1 year-1), P (0, 108,216 g palm-1 year-1) and K (0, 830,1660...

Investigations were carried out to study the impact of inorganic fertilizer substitutions by vermicompost on productivity of coconut during 2001 to 2009 at CPCRI, RS, Vittal in a 22 year old coconut garden under laterite soil. The treatments viz. recommended inorganic fertilizer (500g N, 320g P 2 O 5 and 1200g K 2 O palm/year), 25 % of N in the for...

Coconut leaf vermiwash (CLV) was produced from actively vermicomposting coconut leaf litter + cow dung substrate (10: 1 w/w basis) by Eudrilus sp. It significantly increased the seedling vigour index of cowpea and paddy at 1: 10 and 1: 15 dilutions in laboratory trials. Field trials carried out in red sandy loam soil (Arenic Paleustults) resulted a...

The present study was undertaken to test the stability of a spectral mixture modelling method by applying the model to produce land-cover maps of coconut in Kasaragod district, Kerala. Classification results from applying the Spectral Mixture Analysis (SMA) were assessed by comparison with ground-truth data. SMA was performed and evaluated based on...

Investigations were carried out to assess the biomass available for recycling from coconut based high density multispecies cropping system (coconut, clove, banana and pineapple) under graded levels of fertilizers (full, two-third, one-third, one-fourth and one-fifth of the recommended level of fertilizer for each of the component crops and control)...

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...
