Evaluation of Lipolylic characteristics of cow and buffalo curd prepared using select autochthonous lactic acid bacteria
The aim of this study was to evaluate the lipolytic characteristics of curd in industrial and home production it is the presence and chemical state of milk fat that impart characteristic physical chemical and sensory properties to most of the dairy products. Flavor enhancement that occur are due to proteolysis, lipolysis and glycolysis. It is well known that curd cannot be kept for long at ordinary conditions. Therefore different methods are applied to restrict the growth of undesirable microorganisms. One of the valuable properties of starter culture is their ability to inhibit growth of undesirable microorganisms... It is necessary to identify the cultures Lysis of lactic acid bacteria plays a crucial role in dairy fermentation and ensures the involvement of the intracellular starter enzymes, particularly fatty acids, in the gradual process of curd flavour formation. A direct correlation exists between the stability of cell walls and accumulation of bitter flavour in cow curd and buffalo curd. In Industrial and home production it is the presence and chemical state of milk fat that impart characteristic physical chemical and sensory properties to most of the dairy products. Lower lipolytic activity was observed in the curd samples prepared using Lactococcus lactis subsp. lactis biovar diacetylactis. The highest lipolysis was observed in the curd samples prepared using Lactococcus lactis subsp. cremoris. On storage of curd samples at refrigeration temperature 5.00 ± 0.5ºC the free fatty acid contents were high in the B1Lc curd sample. It was found that the free fatty acid contents was low in C2Ld curd samples.
Compatibility of native species of entomopathogenic nematode, Steinernema abbasi (Nematoda: Rhabditida) with pesticides registered in India
This paper reports the compatibility of native species of entomopathogenic nematode, Steinernema abbasi with pesticides (ten insecticides, six fungicides and six herbicides) that are registered for agricultural use in India. It was investigated how these chemical pesticides affected the viability and virulence of infective juveniles (IJs) of S. abbasi when exposed directly to them at recommended concentrations. After the IJs were subjected to the intended pesticidal concentrations, which was highest recommended dose specific to the type of pesticide, up to 72 hours, data on their survivability was documented. Thereafter, infectivity of the surviving IJs was documented by inoculating them on 4th instar larvae of Galleria mellonella under laboratory conditions. With the exception of cartap hydrochloride (100%) and acetamiprid (19.1%) among insecticides, carbendazium + mancozeb (23.5%) and tricyclazole (14.1%) among fungicides and pendimethalin (19%) and 2, 4 - D sodium salt (11%) among herbicides, all the tested pesticides showed less than 10% nematode mortality after 72 hours of exposure. The tested pesticides had no negative effect on the pathogenicity of IJs, since 100% mortality of Galleria mellonella larvae was observed in each treatment after 72 hours of inoculation. The experimental findings of this work are noteworthy in light of future prospects for combination treatments under the Integrated Pest Management programme against economically important insect pests of crops.
Evaluation of Physico-Chemical Characteristics of Different Varieties of Pearl Millet
Millet constitutes one of the most reliable dry-season crops in terms of global agricultural production. Pearl millet is the main millet crop grown in India. The present study was undertaken to investigate the physico-chemical composition of five different varieties of pearl millet. The evaluation of five different varieties viz; Pusa composite (383), Pusa composite (701), Dhanshakti, MBC-2 and Local variety-ACRA for physical parameters (seed weight, seed density, swelling capacity and swelling index), chemical parameters (moisture, crude protein and ash content) and antinutritional parameters (phytic acid and polyphenols) was carried out. The highest seed weight (11.87 g), seed density (1.24 g/ml), swelling capacity (0.65 5) and swelling index (0.55 %) was exhibited by Dhanshakti variety, whereas the lowest was observed in Local variety-ACRA. Maximum moisture content was observed in Local variety-ACRA (11.23 %), crude protein and ash content (11.13 and 1.87 %), respectively recorded in Dhanshakti. In contrast, the highest values for phytic acid (765.96 mg/100 g) and polyphenols (601.73 mg/100 g) were found in Local variety-ACRA.
Effect of establishment methods and weed management practices on weed control, growth and productivity of blackgram in tarai region of India
A field experiment was carried out in blackgram to find out the effect of various weed management practices and different establishment methods on growth, weed density, weed dry matter, yield and yield attributes at N. E. Bourlag crop research center of G.B.P.U.A&T, Pantnagar during kharif season of 2016. Field experiment was consisted of 2 main plot treatment i.e. raised bed and flat bed and 4 sub-plot treatment i.e. weedy check, Pre emergence (PE) application of pendimethalin 30EC @1.0 Kg/ha, post emergence (PoE) application of imazethapyr 10 SL @ 0.055 kg/ha applied at 20DAS and PE application of pendimethalin 30EC @1.0 Kg/ha + PoE application of imazethapyr 10 SL @ 0.055 kg/ha applied at 20DAS applied as which was carried out under a split plot design. Growth parameters, yield, yield attributes, weed density and weed dry matter was not affected significantly by different establishment methods except number of pods per plant, although raised bed method produced better result than flatbed method. Significantly, higher yield attributes and grain yield per hectare was obtained due to different weed management practices. Pendimethalin @1.0kg/ha 30 EC as PE, imazethapyr @0.055 kg/ha 10SL at 20 DAS as PoE, PE application of pendimethalin 30EC @1.0 Kg/ha + PoE application of imazethapyr 10 SL @ 0.055 kg/ha applied at 20DAS produced significantly higher productivity by 133.7 and 100.4 and 221% over weedy check respectively. Lowest weed density and weed dry matter was recorded under PE application of pendimethalin 30EC @1.0 Kg/ha + PoE application of imazethapyr 10 SL @ 0.055 kg/ha applied at 20DAS.
Assessment of leveraging impacts of micronutrients, biofertilizers and growth regulators on biochemical characters of pomegranate cv. Bhagwa
Assessment of leveraging impacts of chelated micronutrients, growth regulator and biofertilizers on biochemical characters of pomegranate (Punica granatum L.) cv. Bhagwa” was carried out on experimental fruit orchard of Department of Horticulture, VNMKV., Parbhani, during Mrig bahar in 2018-19 and 2019-20. This experiment was laid out in Factorial RBD, which is replicated twice with two factors i.e. Factor A: methods of plant propagation (P) i.e. P1: Air layered plants, P2: Tissue cultured plants and Factor B: different nutrients concentrations i.e. N1: Chelated micronutrients (CM.) @ 3.0 g/lit, N2: CM. @ 4.0 g/lit, N3: GA3 @ 75 ppm, N4: GA3 @ 100 ppm, N5: Biomix @ 0.3%, N6: Biomix @ 0.4%, N7: CM. @ 3.0 g/lit and Biomix 0.3%, N8: CM. @ 3.0 g/lit and GA3 75 ppm and Biomix 0.3%, N9: CM. @ 3.0 g/lit and GA3 75 ppm, N10: GA3 75 ppm and Biomix 0.3%, N11: Control. The result revealed that biochemical characters of fruits regarding TSS, total sugars, reducing sugars, ascorbic acid and anthocyanin content increases with application of chelated micron. @ 3.0 g/l + GA3 @ 75 ppm + Biomix @ 0.3% with interaction of tissue cultured plants. Whereas, acidity of fruit is reduced due to combined application of chelated micron. @ 3.0 g/l + GA3 @ 75 ppm + Biomix @ 0.3% with interaction of tissue cultured plants. This foliar application has produced significantly superior effect on biochemical parameters.
