Early Vegetative Growth and Fibre Yield in Tossa Jute (Corchorus olitorius L.)

Field experiment was conducted for disease management with seven eco-friendly treatments in Corchorus olitorius jute during 2012-2013 under randomized block design (RBD) in three replications with variety JRO-524. The ecofriendly treatment 50% N: P: K + seed treatments with Azotobacter and phosphorus solubilizing bacteria (PSB) @ 5g/Kg+ Trichoderma viride (seed treatment @ 5g/Kg of seed and soil application @ 2Kg/ha at 21DAS) + Psuedomonas fluorescens spray @ 0.2% at 45DAS was found superior with minimum per cent disease incidence (3.46 and 1.43%) as compared to control (13.17 and 4.96%). The second best treatment was found with Farm yard manure (FYM) @ 5t/ha + seed treatment with Azotobecter and PSB @ 5g/Kg+ T. viride (seed treatment @ 5g/Kg of seed and soil application @ 2Kg/ha 21DAS)+ P. fluorescencs spray @ 0.2% at 45DAS and showed 3.61 and 2.0% disease incidence. The treatment with N: P: K @ 60:30:30 and seed treatment with carbendazim 50WP @ 2g/Kg at 45DAS showed 4.56 and 2.10 % disease incidence. Dry fibre yield was highest (30.33q/ha) in the plots treated with FYM @ 5t/ha + seed treatment with Azotobacter and PSB @ 5g/Kg+ T. viride (seed treatment @ 5g/Kg of seed and soil application @ 2Kg/ha at 21DAS) + P. fluorescencs spray @ 0.2% at 45DAS) and it was lowest in untreated control (15.69 q/ha).Variation in yield was attributed due to difference in plant height.

SUMMARYField experiments on the effect of moisture regimes and fertilizer application on fibre yield of two jute varieties showed that JRO 632 (Corchorus olitorius L.) produced significantly more fibre, utilized moisture more efficiently and extracted water from deeper layers than did JRC 212 (Corchorus capsularis L.). Scheduling of irrigation at 20% available soil moisture (ASM) gave the highest fibre yield in normal (1970) and drought (1972) years but unirrigated conditions (dry regime) gave highest yield in a year of excess rainfall (1971). The consumptive use (CU) increased from dry to wet regimes and the water use efficiency (WTJE) was greater in dry regimes in normal as well as in excess rainfall years. But the WUE was maximal when the crop was irrigated at 60% ASM in the drought year. The water requirement of the jute crop was 490 mm in the normal and excess rainfall years (20% ASM and dry regime respectively) while in the drought year it was 560 mm (20% ASM). The moisture extraction was more from deeper depths in the dry regime and only from shallower depths in wet regimes.The fibre yield increased with increase in nitrogen application from 40 to 80 kg/ha. Application of 40 kg P2O5 and 40 kg K2O/ha did not improve the fibre yield in the excess rainfall and drought years. In the drought year (1972) irrigating at 20% ASM and 80 kg N/ha and in the excess rainfall year (1971) the dry regime with 40 kg N/ha produced highest fibre yields. There was not much variation in CU and WE of the crop due to different fertilizer levels. The WUE was increased by irrigating at 20% ASM with 80 kg N/ha in a crop rotation system where P and K were applied to preceding crop.

Sowing Season

The present study aimed to explore the Rank correlation of seed and fibre yield characters in Jute (Corchorus olitorius). Jute cultivation availability of quality seed remains a potential factor as it deals with the fibre. Studying the correlation between both seed and fibre characters at the same time in jute is a complex matter since the sowing season, agricultural practices vary in both the cases. Varieties producing high fibre and seed yield are necessary to meet the deficit in seed supply for the jute producing farmers of West Bengal, India. In this study, the experimental material consisted of thirty six jute (Corchorus olitorius L) crosses along with two check varieties. Fibres were harvested at 120 days and the seeds at maturity. The variability in most of the yield (fibre and seed) contributing characters was mainly due to genotype with some extent of environmental influence. To obtain a clear understanding of the inter-relationship between seed and fibre characters a rank correlation was performed instead of simple correlation. A strong positive correlation was found which helped us in finding lines with both high seed and fibre yield. Furthermore, a fibre quality test was also conducted for estimating the fineness and strength of the fibre.

An experiment was conducted to examine the magnitude of genetic diversity and characters contributing to genetic diversity among 81 tossa jute genotypes. Cluster analysis based on Euclidean squared distances and ward’s method, the genotypes were grouped into ten distinct clusters. Analysis reveals that stick weight contributes maximum to the phenotypic diversity (65.52%) followed by green weight (13.64%) and fibre yield (10.10%). Among the clusters Cluster IX recorded highest mean fibre yield (19.91g) followed by Cluster VII (18.94g) and these clusters also recorded high mean values for plant height, basal diameter, green weight and stick weight. The highest inter- cluster distance was 186.80 (between clusters II and X) followed by 161.26 (between clusters IV and X), indicating the wide genetic diversity among these clusters. The highest intra-cluster distance was observed in cluster II (20.34) and the lowest in cluster X (3.17). The average inter-cluster distances were higher than the average intra-cluster distances, which shows the presence of wide genetic diversity among the genotypes of different clusters than those of the same cluster. The first two principal components, whose Eigen values are greater than one, accounted for 74% of the total variation among the five characters. The information obtained from diversity analysis is useful in planning further breeding programme for tossa jute improvement.
