A pilot study was conducted during 2013-16 at Regional Sericultural Research Station, Kalimpong, West Bengal research farm with five treatments and four replications to study the integrated effect of mixed cake and FYM on existing mulberry variety BC259 (Morus alba L.). This study was also extended to check its adverse effect on silkworm rearing of SK6xSK7 silkworm (Bombyx mori L.). The mixed cake was applied through ‘Spic Surabhi'. The main ingredient in Spic Surabhi was oilseed cake of Neem, Groundnut, Castor and Sesame with Turmeric powder and Pungamia extracts. These oil cakes were fortified well together in a well balanced mixed with NPK. Based on data analyzed, it was found that the integrated application of mixed cake @1.0 mt + FYM@ 7.5 mt ha-1 (T4) and mixed cake@1.5 mt + FYM@ 5.0 mt ha-1 (T5) performed economically and significantly better than rest of the treatments. The annual leaf yield of treatment T4 and T5 ranged from 16.44 to 16.49 mt ha-1 with 32.0 to 32.42% leaf yield gain against control T1 (12.45 mt ha-1). The nutritional quality like moisture content, total chlorophyll, total soluble protein, total soluble sugar, total N, total P and crude protein were also recorded higher with T4 and T5 than rest of the treatment. Silkworm rearing performance reveals that the mulberry leaves with above nutrient combinations do not have an adverse effect on single cocoon weight, cocoon yield and shell% respectively. The higher cost-benefit ratio T4 and T5 was 1:2.03% with net profit . 2.13 Lakhs ha-1 year-1 after the application of T4 and T5 treatment than control.

Sheath blight of rice is an important and destructive disease caused by Rhizoctonia solani. Fifty rice sheath blight samples were collected from different parts of eastern UP and pathogenic variability was studied on different rice cultivars Viz.,Pusa Basmati-1(PB-1) susceptible rice cultivar and Tetep moderately resistant cultivar. The perusal of data indicated significant differences in the aggressiveness of isolates. The total of 50 isolates was grouped into four group as weakly virulent (WV), moderately virulent (MV), virulent (V) and highly virulent (HV), representing 30, 46, 20 and 4% of isolates, respectively. Majority of the isolates were moderately virulent on susceptible cultivar (PB-1), whereas in moderately resistant cultivar (Tetep) majority of isolates were weakly virulent representing (88%) followed by moderately virulent (8%) and virulent (2%).

Okra (Abelmoschus esculentus) samples were subjected to three different drying methods using solar, sun and oven. Chemical and sensory properties of the dried okra samples were investigated using fresh okra as a control. Natural open sun drying took about 191/2 hours to dry the okra to a constant moisture content of 12.67% (w/b), solar dryer took 12 hours to dry to 12.50% (w/b) and hot air oven took about 101/2 hour to dry to 5.50% (w/b). The results of chemical properties showed that the fresh okra contained 75.67% moisture, 11.99 % crude protein, 0.34% crude fat, 1.03% crude ash, 0.50% crude fiber, 10.47% carbohydrate, 92.90 Kcal energy value, 12.83 cP viscosity and 26.04 mg/100 g vitamin 'C'. The open sun dried okra contained 21.93% crude protein, 2.56% crude fat, 9.33% crude ash, 8.05% crude fiber, 45.46% carbohydrate, 292.60 Kcal energy value, 13.10 cP viscosity and 17.14 mg/100 g vitamin 'C'. Solar dried okra contained 29.40% crude protein, 4.91 % crude fat, 10.12% crude ash, 8.71% crude fiber 34.36% carbohydrate, 299.23 Kcal energy value, 15.47 cP viscosity and 19.21 mg/100 g vitamin 'C'. Oven dried okra contained 17.97% crude protein, 2.20% crude fat, 9.23% crude ash, 6.12% crude fiber, 58.98% carbohydrate, 333.60 Kcal energy value, 21.13 cP viscosity and 14.08 mg/100 g vitamin 'C'. The above results showed that the drying methods used have a significant effect (p<0.05) on the physicochemical properties of the dried okra. The nutritional and sensory quality of the solar dried okra is superior to open sun and oven dried okra. It was concluded that better quality shelf stable dried okra can be obtained by solar drying method.

Intercropping is a common practice which allows for better resource use efficiency, increases yield stability as compared to monocropping. The present research work was conducted at Horticultural Research Station, Mondouri, Faculty of Horticulture, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, India from July-December, 2017. The experiment was laid out in Randomised Block Design (RBD) with five treatments and four replications. The treatments were as follows: T0 =cauliflower as monocrop, T1=cauliflower intercropped with marigold, T2= cauliflower intercropped with Balsam, T3= marigold monocrop, T4= balsam monocrop. When cauliflower intercropped with balsam (T2), cauliflower size and quality, balsam flower number and overall yield attributes were significantly increased. Land resource was properly utilized. So, cauliflower intercropped with balsam is the best treatment. This technique will help the marginal farmers for more profit.

The study aimed to investigate the adsorptive interaction between metal hexacyanoferrates (II) and natural antifungals. Nickel, manganese and copper hexacyanoferrates (II) were synthesized and characterized by elemental and spectral analysis. The antifungal potentials of each metal hexacyanoferrate (II) at 10 mg/mL were combined with two natural antifungals: coconut (Cocos nucifera) and ochro (Abelmoschus esculentus) leaves. The ethanol and acetone extracts at 20 mg/mL and 10 mg/mL, respectively have been evaluated against fungus Candida albicans. The antifungal potential was executed by the disc diffusion method. The acetone and ethanol extract of A. esculentus at 10 mg/mL paired with copper and nickel ferrocyanides, respectively were found to possess the most effective antifungal potential. Each interaction pair was also characterized by spectral studies and phytochemical analysis.

With bagasse as carriers, a sequencing batch three phase fluidized bed biofilm reactor for cane sugar wastewater treatment has been investigated. The experiments showed that, with the initial COD, NH3-N and TP concentrations of 578.9~876.8 mg/L, 39.9~55.7 mg/L, 3.61~5.60 mg/L, respectively, after the aeration time of 2~3.5 h, the effluent COD and NH3–N were lower than 120 and 10mg /L, which achieved the national primary discharge standard, and the highest removal rates of COD, NH3-N and TP reached to 97%, 91.39% and 99.21%, respectively. Considering both the treatment performance and energy consumption, the optimum air flow rate was determined as 40~80 L/h, and the favorable pH range was found to be 5~8.Bagasse, as carriers in the sequencing batch reactor, had better characteristics of the bio-film attachment and performance of wastewater treatment. Using bagasse as carriers could achieve the purposes of reducing cane sugar wastewater treat-cost and contamination of the environment.

Rice (Oryza sativa L.) is the most vital staple food crop in Asia and human consumption accounts for 85% of total production of rice. The conventional rice production system with standing water not only leads to wastage of water but also causes ecological problems and reduces the use-efficiencies of inputs. An effort to increase crop and water productivity either by reducing water consumption or by increasing the yields or both will automatically facilitate higher growth in agricultural production. Keeping these in view, field experiments were conducted in 2011 and 2012 at the University Farm, G.B. Pant University of Agriculture and Technology, Pantnagar. Data were collected to assess the growth, yield, yield components and use efficiencies of nutrient and water of rice under drip irrigation and conventional irrigation practices. The experiment was laid out in a Randomized Complete Block Design comprising of 4 replications and 4 treatments. Results show that growth, yield and their attributes, input use and economics differed significantly among the treatments in both years. All the growth factors studied were found to be higher in the flatbed method of Dry Seeded Rice (DSR) and drip irrigation. Shoot height was found significantly maximum in DSR with flood irrigation. Similarly, yield and yield attributes were superior in the flatbed method of DSR with drip irrigation in both years. Water and nutrient use efficiencies were found to be maximum in drip irrigated rice with 52% water savings than traditional flood-irrigated rice. It is also noted that Returns and Benefit-Cost ratio were higher with drip-irrigated rice than flooded irrigated rice.
