III. Title: Assessment of different weed management strategies in direct seeded Rainfed Rice in bunded uplands (Baid Khet) of Red laterite tracts of Purulia, West Bengal during Kharif season .

Thematic Area: Crop Production (Weed Management)

Problem Area:  In Purulia out of total 2.72 lakh ha. under Khari fpaddy  about 60 % is occupied by upland where even after introduction of HYVs and Hybrids  poor crop yield (2.2-2.5 t/ha) is a regular phenomena. Delayed transplanting and sometimes insufficient rainfall for land preparation brought down the overall production of Rice in the District.

Important Cause:- Although monsoon breaks between 7-15 June and farmers resort to sowing seeds for upland rice between 15-20 th. June, our experience reveals that transplanting could never be done between 25thJuly and 5th  August in Normal Rainfall year. In years of abnormal rainfall it may extends upto end of August as farmers always try to transplant Rice under any circumstances as it is the only crop for most of the farmers and the major source of fodder. But even after all such efforts sometimes Farmers have to leave the field due to “very erratic rainfall pattern” that makes transplanting impossible.

As a result, famers have to transplant either over aged seedlings susceptible to pest and disease attack or left the field uncultivated which ultimately brought down the productivity and overall production of the District.

To address this issue we have tested the feasibility of DSR technique for the last three years and the yield level of DSR are comparable or even higher with good management practices to the CT-TPR in some of ours observation. Although, DSR technique have been emerged as an alternative crop management method against imminent water crisis, climbing labour cost and labour scarcity to increase water productivity, system sustainability and profitability; high weed infestation is a major constraint for broader adoption of DSR. Weed growth reduces grain yield in the range of 30-70 %.

Therefore, adequate weed management strategies including identification of herbicides that are effective against a wide spectrum of weeds needs to be adopted.

Production System: Rice – Fallow – Fallow

Micro Farming situation: Rainfed bunded upland , season- Kharif, Soil type – sandy loam textured, acidic in nature (pH 4.8 – 5.8) low in available phosphate, potash and poor in organic matter content.

Technology for Testing: Different weed management strategies in direct seeded Kharif Rice.

Existing Practice: Farmers transplant aged seedlings (40-50 days old) up to mid august and apply 40:30:30 Kg/ha N:P:K as basal followed by pre emergence application of Pretilachlor 50% @ 500ml/acre at 1-2 DAS and 20 Kg N/ha as top dressing at 30-35 DAS.

Hypothesis: Experiments conducted in different parts of the country shows, by adopting direct seeding techniques with an effective and sustainable weed control strategy, the farmers could increase the productivity, reduced cost of cultivation by, increased the cropping intensity and earned an additional income with less effort. These technologies also helps in timely sowing under less rainfall situation, conserves soil moisture and requires less water, saves tillage cost and cost of labour in times of scarcity and the soil is protected from erosion due to the retention of surface residues and reduce organic matter depletion.

Objective: To assess the performance of different strategies in managing weeds in Direct seeded Rice over farmers practice on yield of Rainfed Rice during Kharif  season

 IV. Title: Standardization of recommended crop management strategies for improving the productivity of Sugarcane in Red laterite tracts of Purulia, West Bengal .

Thematic Area: Crop Production (Integrated Crop Management)

Problem Area: In Purulia Sugarcane is cultivated in about 886 ha., production 38744 MT and Av. productivity is 437 q/ha. Sugarcane is the major crop after Rice in about 12 moujas of Arsha Block in the foothill of Ayodhya Range (lies between 23°20′ and23°15′  North Latitude and 86°15′ and 86°5′ East Longitude ).In this Patch, Sugarcane is grown as a rainfed crop following in situ soil moisture conservation technique for the last 100 years or more. Here planting of sugarcane usually starts from 15th March and continuous upto 20th April and harvested during  Feb to 15th March. From 1975 onwards they are growing Co-527. For the last 15 years they are observing gradual decrease in yield (80-100 t/ha to 40-50t/ha).Increased pest and disease problem that ultimately brought down their profit margin. Low profit leads to shifting to other less remunerative and new crop for the farmer..

Important Cause:-a)Due to continuous cultivating the Co 527 for last 30-40 years quality of planting material deteriorated. Continuous cultivation leads to heavy insect pest and disease problem. Red Rot Infection starting from seedling to maturity. White ant and early shoot borer attack during initial growth stage. Borer attack (internode and top bore) starts 1-1.5 month after planting.

  1. b) Heavy weed infestation leads to 8-9 weeding that not only involves high labour cost and also reduce fertilizer use efficiency.
  2. c) Poor stand establishment due to non-availability of Rain and High Temperature immediately after planting.

V. Title: Assessment of the effect of seed hardening with organics on seed quality of Black gram during Kharif season under rainfed unbunded upland situation of Red & Lateritic Zone of Purulia District.

Thematic Area: Crop Production(Seed Production)

Problem Diagnosis: Importance of good quality seed has been very important for well recognized successful production of any crop especially in pulses. Black gram being an important pulse crop of dry region, hydration and dehydration of seed in this crop assumes importance to combat moisture stress during germination in field. Recently beneficial effect of seed in vigouration with organics has also been well correlated to maintain vigour and viability of seed. The technique of pre-conditioning of seeds was, therefore developed to mitigate various adverse effects (Chittapur and Kulkarni, 2014). Therefore, the present investigation to be carried to know the effect of organics on germination, seedling, vigour in Blackgram.

Important Cause: Despite the high yielding potential and various advantages of Blackgram, the yield per unit area of the crop is low in Purulia. Poor germination is one of the main hindrances limiting the production of Black gram. Lack of moisture in the top soil at the time of seed sowing is one of major cause poor crop stand & yield . The use of Black gram seeds of low physiological quality is a common practice under Red & Lateritic Production system, leading to inadequate plant population in the field also.

Production System: Black gram based production system(Black gram-Fallow-Fallow)

Micro-farming system:  Unbunded rainfed uplands, season Kharif, soil type : Coarse textured, acidic, low in available Phosphate, Potash, Calcium & very poor in organic matter, suffering from periodic drought at critical growth stages.

Technology for testing: The present investigation to be carried to know the effect of organics for improving germination & field emergence of Kharif Black gram.

Existing Practice: Farmers grow Black gram (without pre-soaking) by broadcasting of seeds with a depth of sowing 5-10 cm with a seed rate of 20-25 kg/ha.

Hypothesis: The Black gram seeds were pre-soaked in the Vermiwash/ Cow urine/Normal water above mentioned solutions separately for 1 hour in 1:2 proportions followed by drying for 7 days under ambient conditions to original moisture content. The rationale is that sowing soaked seed decrease the time needed for germination and allow the seedling to escape soil physical conditions & aims to reduce the time of seedling emergence, as well as synchronize and improve the germination and field emergence percentage.

Objective: To study the influence of different method of pre-soakingwith organics on germination and field emergence of Black gram.

VI. Title: Assessment of the effect of soil test based fertilizer recommendations for Kharif Black gram under red and lateritic soils of Purulia District of west Bengal

Thematic Area: Soil Health & Fertility Management (Integrated Nutrient Management)

Problem area: Total area and productivity of Kharif Black gram in Purulia District is 1512ha and the average yield is 5.6 q/ha and the crop is grown in the unbunded uplands during kharif season. Among the various constraints for low productivity of kharif Black gram, less and imbalance use of fertilizers is one of the main reason related with lower productivity of Black gram. Farmers of this district apply only the ash and they are not following neither blanket recommendations given by the State Agriculture Department nor as per the recommendations done by Soil testing of a particular plot.

Important causes: Fertilizers play a pivotal role in increasing production as the crop yields may be increased considerably by using appropriate doses of fertilizers. The soil health status of unbunded upland of Purulia district is very poor and it is acidic in nature, very low in organic matter and available plant nutrients.

Production System: Black gram based production system (Black gram – Fallow – Fallow).

VII. Title: Assessment of soil application of boron on yield and soil properties of kharif paddy under red and lateritic soils of Purulia District of West Bengal.

Thematic Area: Soil Health & Fertility Management (Integrated Nutrient Management)

Problem area: Paddy cultivation of this district is the primary crop during Kharif season. 77% of the net-cropped area is under Aman paddy cultivation. Out of the total agricultural holding about 73 % belongs to small and marginal farmers. The crops are grown mostly under rainfed condition, generally with low fertilizer and without micronutrient consumption. Thus per hectare production is also low as compared to other district of West Bengal.

Important causes: Boron deficiency occurs due to several factors including drought, low soil pH and B leaching and fixation. Declining productivity trends in rice growing countries are due to the micronutrient deficiencies. Boron (B) deficiency is of particular importance since it affects the flowering and plant reproductive process and therefore directly affects grain yield.

Production System: Kharif Paddy based production system (Kharif Paddy – Fallow – Fallow).

Micro farming Situation:  Bunded rainfed upland (Baid), Season: Kharif 2018, Soil Type: Coarse textured, acidic, low in organic matter, low in water holding capacity and low in available plant nutrients (N,P,K,B).

VIII. Title: Assessment of application of Ash and Vermicompost to increase the bulb size in Kharif Onion in upland situation under rainfed condition in Kharif season of Purulia district, West Bengal

Thematic Area: Horticulture (Vegetable Crops) Off-season vegetables..

Problem Diagnosis:

Kharif onion is grown in unbunded upland situation under Rainfed condition in Purulia district to meet domestic requirement as well as for sale in the market. In most cases it is found that bulb size of Kharif onion is very small due to application of least amount of manures. The upland soil is acidic in nature and suffers from unavailability of nutrient during the season. Farmers use very less amount of Potash and manures during field preparation which is also one of the main reasons of small sized bulb.

Production System: Vegetable – Fallow – Fallow

Micro farming Situation: Rainfed condition, unbunded sloppy land situation, season – Kharif, soil type sandy soil, shallow soil depth (upto 6”).

Technology for Testing: Application of easy availability of ash and vermicompost as a remedial measure for increasing bulb size of Kharif onion.

Existing Practice: Farmers grow Kharif onion in unbunded upland situation under Rainfed condition by using minimum amount of FYM @ 600 q/ha and N:P:K. (General recommendations).

II. Title: Evaluation of bio-effectiveness of low cost eco-friendly pesticide formulations against diseases of Tasar silk worm in Purulia district of West Bengal.

Thematic Area: Plant Protection (Integrated Disease Management)

Problem Area:  In Purulia district of west Bengal rearing of tasar silk worm rearing dates back to early 20th century and had been a common practice of the rural community especially among the tribal farmers. However, unscientific conventional rearing practice has led to more losses than return which thereby forced farmers to shift to other more profitable farming options leaving tasar cultivation to some very limited pockets of the district. because of which the farmers fail to achieve minimum return and thus do not find the tasar silkworm cultivation as a profitable enterprise.

Important Cause:- Tasar silkworm rearing is done outdoor owing to the fact that the silkworms cannot be domesticated like that of Bombyx mori (mulberry silk worm). The optimum cocoon yield is drastically reduced due to several fungal, bacterial and viral diseases of tasar silkworm. Curative measures to keep in check the pest and diseases of silkworm cannot be undertaken and one has to rely on preventive measures to deal with the pest and disease management for which proper knowledge and skill is mandatory.

Therefore, bringing about some easy, low cost, eco-friendly silkworm disease management options might address the present problem effectively.

Technology for Testing:-  Evaluation of bio-effectiveness of Tasar Keet Ousadh (T.K.O) which is formulated by mixing para-formaldehyde, benzoic acid and slaked lime in the ratio 0.5:2:97.5, Jeevan Sudha which is mixture of 3 medicinal plants (aloe vera, kalmeg and bhoomi amla) in the ratio 2:1:1 and Jeevan Suraksha which is formulated by mixing lime, bleaching powder and turmeric in the ratio 8.5:1:0.5 against diseases of tasar silk worm

Existing Practice : –   Farmers are mostly unaware of the diseases of tasar silk worm and cultivate the crop in traditional conventional method which does not include any disease management option.

Hypothesis: – Experiments conducted in Central Tasar Research and Training Institute and different parts of the country shows that disease management using the above mentioned formulations as preventive approach has proven to effectively reduce the diseases of tasar silk worm thus rendering higher number of cocoons per 100 dfl which further ensured profit over conventional tasar cultivation.

Objective: – To assess the performance of Tasar Keet Ousadh (T.K.O), Jeevan Sudha and Jeevan Suraksha against diseases of tasar silk worm

Treatments:-

Farmers Practice: Farmers are mostly unaware of the diseases of tasar silk worm and do not undertake any management options for management of diseases of tasar silk worm
