RESUMEN
The study conducted “Analysis of constraints on production and marketing of tasar and mulberry silk in Chhattisgarh” included four districts i.e. Bastar, Korba, Jashpur and Raigarh. In each district one block, from Bastar district Jagdalpur block, Jashpur district Kansabel block, Korba district Korba block and Raigarh district, Dharamjaigarh block has been selected for the study based on maximum tasar and mulberry seed centres and 16 villages has been selected for the study, information about the primary data was collected from 160 cocoon growers in selected areas, though well-prepared interview schedule/ questionnaires. The study observed that tasar and mulberry cocoon grower and their marketing was found to be major constraints unavailability of labour during the production process was ranked first according to measurement, respectively silkworm, lack of knowledge in the maintenance of host plant, unavailability of the good quality plantation, lack of technical guidance, unavailability of input on time, difficulty obtaining DFL’s, lack of knowledge about training and pruning of host plant among marketing constraints suffers SHG’s were obtaining rank first lack of marketing facilities, followed by the poor quality of cocoon, difficulties of grading of the cocoon, lack of market information regarding the price of tasar and mulberry cocoon, lack of proper price received by cocoon growers, transportation cost, the lake of proper payment facility to silk grower and lack of storage facilities of cocoon despite all the constraints the area has great potential for silk production. Therefore cocoon growers in the study area can be provided with adequate knowledge in both tasar and mulberry cocoon production to enhance the production and productivity of cocoons.
RESUMEN
The present investigation has been conducted in rice crop during Kharif 2021-22at Students’ Instructional Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.), India. The population of six major insect pests was recorded viz. Rice Yellow stem borer (Scirpophaga incertulus), Rice Leaf folder (Cnapholocrocis medinalis), Rice ear head bug (Leptocorisa acuta), Brown plant hopper (Nilaparvata lugens), White backed plant hopper (Sogatella furcifera)and Green leaf hopper (Nephotettix nigropictus) that cause most damage at different crop growth stages initiated after sowing till harvesting. The maximum population of yellow stemborer was observed on rice crop at 36th SMW (12.20 per cent dead heart). The infestation of dead heart was non-significant positively correlated with minimum, maximum temperature and RH% (0.433, 0.010 & 0.253 respectively) and negatively correlated with rain fall (0.081) whereas, significant negatively correlated with sunshine (0.552*). The maximum population white ear in 40th SMW (16.80 per cent). The infestation of white ear was non-significant negative correlation with minimum, maximum temperature (-0.062, -0.167) and positive correlation with RH & rain fall (0.244 & 0.173) whereas, significant positive correlation with sunshine (0.703*). Maximum leaf folder population was observed during 35th SMW (16.35 per cent). and infestation of leaf folder was non-significant positive correlation with minimum temperature & RH (0.427 & 0.505) and negative correlation with maximum temperature, rainfall and sunshine (-0.079, -0.030 & -0.291). The maximum population was recorded of ear head bug in 38th SMW i.e., (10.90 ear head bug/hill respectively.). The infestation of ear head bug was non-significant positive correlation with minimum temperature, RH, rainfall & sunshine (0.061, 0.176, 0.155 & 0.210) and negative correlation with maximum temperature (-0.407). The peak mean population of BPH was recorded in 37th SMW i.e., (11.25 brown plant hopper/hill respectively.) Itwas non-significant positive correlation with minimum temperature & RH (0.463 & 0.357) and negative correlation with maximum temperature & rainfall (-0.066 & -0.088) whereas, significant negative correlation with sunshine (-0.597*), The peak mean population of WBPH was recorded in 38th SMW i.e., (12.80 white backed plant hopper/hill respectively.) It was non-significant positive correlation with minimum temperature, RH & rainfall (0.300, 0.337 & 0.185) and negative correlation with maximum temperature (-0.300) whereas, significant negative correlation with sunshine (-0.094*) and the maximum population of green leaf hopper was recorded in 37th SMW i.e., (10.80 green leaf hopper/hill respectively.) with the infestation of green leaf hopperwas non-significant positive correlation with minimum temperature & RH (0.479 & 0.369) and negative correlation with maximum temperature & rainfall (-0.077 & -0.120) whereas, significant negative correlation with sunshine (-0.633*).
