Cocoon silk, a high priced fabric, should be produced in large quantities to meet local and international demands using sustainable farming practices. To determine the effects of planting systems and agroecosystems manipulations on the mulberry growth, leaf yield, and quality for silk worm rearing, six agroecosystems manipulations using pit planting, organic manuring, inorganic fertilization, green and green leaf manuring were evaluated and the best alternative to increase production was selected. Pit planting method and fertilized with any of the following: (1) 100-5050 kg NPK/ha + 10 tons manure + green manure + mulch (LEISAI); (2) 5050-50 kg NPK/ha + 10 tons manures + green + green leaf manure + mulch (LEISA II); and (3) 10 tons manure + green manure + green leaf manure + mulch (Organic Farming I) gave higher mulberry leaf yields (taller mulberry plants, longer shoots, heavier single leaf weights), higher protein contents, and acceptable range of moisture (high moisture contents for young-age worms and low moisture contents for late-age silkworms). The use of sustainable and organic farming techniques can be a good alternative to conventional farming to improve the productivity of sericulture farms.

Selection of P1 seed farmers (ASRs) for different combination of P1 seed cocoon generation and supply to SSPC Vijayapura to produced large scale commercial double hybrid and SK hybrid ds. Sericulture is one of the most important rural industries practiced since several decades. It has certain inherent level to educate Sericulturists, still a wide gap exists between there commended technology and actual adoption by Sericulturists. To plan a suitable intervention strategy, to bridge this gap, it is necessary to understand the present knowledge and adoption level for improved technologies, so also existing mulberry leaf yield and quality seed cocoon generation. Therefore, present study was conducted to know the extent of adoption of improved practices at farmer's level in selected areas of ASR farmers Doddaballapura, Koratagere, Nelamangala and Siddlaghatta covering ve locations with purpose of good quality of seed cocoons generation and to produce quality ds. During the year 2018-19 signicant achievement of SSPC Vijayapura Production of Bivoltine F1 Silkworm Eggs on large scale as per the annual targets of 25 lakhs this centre could record a total production a quantity of 38,40,050 lakhs Bivoltine F1 ds was produced in different combination month wise and ds recovery Table-1&2.

A field experiment was conducted for two years (1994–96) to evaluate three nitrogen fixing bacteria (NFBs) namely Azotobacter, Azospirillum and Beijerinckia as foliar biofertilizers on mulberry (Morus spp.). Foliar application of these bacteria in their specific culture media with half of the recommended dose of N as a basal application of chemical fertilizer were compared with the recommended dose of N (300 kg/ha per year in four equal splits) but without biofertilizer. Other controls for comparison were respective culture media with half N. All the NFBs improved leaf yield over their respective controls (specific culture media). The addition of Azotobacter resulted in significantly greater yield than that given by the recommended dose of N. The Beijerinckia treatment resulted in a leaf yield equal to that from the recommended dose of N and Azospirillum reduced leaf yield in comparison to that from the recommended N treatment although the yield from Azospirillum treatment was more than that from the culture medium treatments. A combination of NFBs where Azotobacter was one of the components improved leaf yield over single NFB treatments. NFBs also resulted in improved leaf quality as indicated by their protein content and their impact on silkworm rearing and cocoon production when treated leaves were subjected to bioassay. The use of these NFBs, particularly the Azotobacter, as a foliar biofertilizer to increase mulberry leaf production has not been investigated before.

A field experiment was conducted at the research farm of Institute of Agriculture and Animal Science, , Chitwan, Nepal from December 2009 to March 2010 to study the green leaf production potential of coriander (Coriandrum sativum L.) cultivars. Ten cultivars of coriander were evaluated in a Randomized Complete Block Design (RCBD) replicated three times. Coriander Local, Marpha Local, Mallika, Surabhi and Kalmi Chhattedar showed better performance as compared to others on growth, yield and quality parameters. The highest green leaf yield (10.09 mt/ha) was recorded in Coriander Local followed by Mallika (9.54 mt/ha), Surabhi (9.40 mt/ha) and Kalmi Chhattedar (9.24 mt/ha). Surabhi was found promising cultivar under late sowing condition because if its highest rosette diameter, number of basal leaves and length of basal leaf Hence, there is good scope of coriander cultivation for green leaf production, however, it is more suitable to sow the seeds in usual tome of sowing for the better performance of all the cultivars.

The study assessed the sensitivity of weather parameters with respect to total green leaf and two leaves and bud (T & B) productivity of tea crop {Camellia sinensis (L.) Kuntze}. The maximum temperature ranging from 20.0 to 29.0 oC during March, May, August and September showed positive relationship with values ranging from 0.26 to 3.38 and 0.22 to 3.22 for green leaf and T & B yield, respectively. Similarly, minimum temperature ranging from 9.1 to 20.0 oC during March and July to October found positive 0.001 to 2.93 and 0.28 to 2.91 for green leaf and T & B productivity, respectively. The mean monthly rainfall amounting 52.7 to 664.7 mm during March, May, July to October and 52.7 to 488.4 mm during June, July, September and October also showed positive sensitivity with values ranging from 0.03 to 0.33 and 0.007 to 0.35 for green leaf and T & B yield, respectively. The relative humidity ranging between 41.2 to 77.3% during April to May for green leaf yield (0.32 to 1.71) and during April to May and October for two leaf and bud yield (0.00 to 1.70) showed positive relationship. So, maximum and minimum temperature between 20.0 to 29.0 oC and 9.1 to 20.0 oC, respectively with rainfall of 52.7 to 488.4 mm and relative humidity 41.2 to 77.3% are the most beneficial weather parameters for tea cultivation at Palampur conditions.

Background: Weeds are one of major threats to crop yield and quality. Weeds compete with cane crop and reduce the yield significantly in a very short period. Planned use of all available farm resources leads to integrated control strategy. The current study aimed to study the use of inter row rotary weeder for integrated weeds management to control population dynamics of weeds in sugarcane crop. The objective of experiment is to find out economical, feasible and easy to use approach to minimize the weed density below the threshold level in sugarcane crop and to minimize the use of chemicals for weeds control to promote organic farming. Method: In this research experiment, at Sugarcane Research Institute, Faisalabad during 2017 and 2018, the treatment includes viz. Application od Click (atrazine and acetochlor) @ 3.75 Liter per hectare as Pre-emergence, Ametryn + Atrazine 80 W.P @ 2.50 kg per hectare as post-emergence, Machanical Inter-culture with Rotary weeder and cultivator plough and earthing up. These treatments in different combinations were compared with control. Results: The application of Pre-emergence weedicide Click (atrazine and acetochlor) @ 3.75 Liter per hectare + Inter culture with Rotary weeder 50 days after planting (DAP) + Inter culture with cultivator plough before earthing up (100 DAP) produced significantly higher cane yield of 105 t. ha-1 and highest net benefits per hectare of Rs. 156250/-. The lowest cane yield of 70 t. ha-1 was noted from the experimental units with Weedy check / control. If farmers use this approach, the use of post emergence weedicides will be minimized and will encourage organic farming with safe and healthy environment.
