The Helicoverpa armigera (Hubner) is a polyphagous pest that is found throughout the world. Due to its damaging nature, it causes quantitative as well as qualitative loss and finally overalleconomic loss in agricultural crop production. So, the present investigation was done by rearing of H. armigera on chickpeas under laboratory conditions. The st...

The present investigations entitled “Studies on seasonal incidence of gram pod borer, Helicoverpa armigera (Hubner) on chickpea crop” were carried out at the Student’s Instructional Farm, Nawabganj of C. S. Azad University of Agriculture and Technology, Kanpur during Rabi season 2021-22 and 2022-23. The highest mean larval populations 4.53 larvae p...

Heat stress is now widely accepted as an important ecological factor influencing growth of plants and production. Rising temperatures as a result of global warming cause heat stress, reducing plant development and potential output throughout the entire globe. A field experiment was carried out at Chandra Shekhar Azad University of Agriculture & Tec...

Neem is thought to be the most useful traditional plant in India. Insecticide, antifeedant, hormonal, antifungal, antiallergic, anti-dermatic, anti-inflammatory, anti-scabic larvicidal, and spermaticidal action are only a few of the uses for the various properties of different Neem tree parts. The key challenge now is to increase food production...

सब्जी उत्पादन का विशेष महत्व है। यह किसानों के लिए बहुत ही लाभदायक व्यवसाय है। यहां जलवायु की विविधता के कारण विभिन्न प्रकार की सब्जियों की खेती सफलतापूर्वक की जा रही है। सब्जियों पर कीटों का प्रकोप अधिक होता है। इससे पैदावार में कमी आती है और किसानों को नाशीकीटों द्वारा नुकसान झेलना पड़ता है। अतः कीटों का नियंत्रण अत्यंत महत्वपूर्ण है। कीटनाशकों क...

Mango is one of the sweetest seasonal fruits growing in the tropics and because of their beneficial elemental composition, they have a higher nutritional value. In most tropical nations, these fruits are available in marketplaces from April to August. Mango plants are attacked by a variety of insect pests, but the mealy bug and fruit fly are the...

Oriental fruit fly Bactrocera dorsalis (Hendel)formerly known as Dacus dorsalisalso called as Papaya fruit fly is a major and key pest of Guava fruit, causing adverse effects in various growth stages from initiation of buds to flowering, from fruit prematurity stage toripeningstage. It is reported to cause 95-100 per cent damage to Guava fruits dur...

The incidence of aphids as sucking pest is common on sugarcane crop in India. The occurrence of sugarcane woolly aphid, Ceratovacuna lanigera (Zehntner) (Aphididae: Homoptera) has been recently noticed to cause damage in sugarcane crop. Earlier the woolly aphid was recorded on sugarcane from North-Eastern States like Nagaland, Assam, Tripura, Sikki...

Considering the food and nutritional security concerns, and post green revolution second generation problems i.e. increasing input use with declining efficiency trends, deteriorating soil health, depleting water resources, pollution, and narrowing profits at the end of farmers, an investigation was carried out on Wheat (Triticum aestivum) crop duri...

Major pests of paddy and their control measures

The present investigation comprised of 28 F1s developed by crossing 8 lines viz., K - 9107, HD – 2733, HD – 2888, WH – 1218, K – 1313, DBW – 187, HD – 3086, and DBW – 107 following half diallel mating design. The 36 genotype (28 F1s + 8 Parents) were sown in Randomized Block Design with three replications in timely sown (TS) condition. On the basis...

The present study was based on the germplasm evaluation experiment involving evaluation of 72 germplasm including three checks viz., Shusk Samrat, NDR-359 and MTU-7029. The field experiment under present investigation was conducted in Kharif season 2019 at the Crop Research Station (CRS) Masodha and lab experiments was conducted in Seed Testing Lab...

The field and laboratory experiment was conducted in Kharif 2016-18 on breeder seed of Asha variety of pigeon pea supplied by STR NSP in charge at New Dairy Farm of C.S.A. University of Agriculture and Technology, Kanpur to investigate the effect of seed polymer coating on growth and yield of pigeon pea. The experiment consisted of four seed treatm...

The present study consists of 32 rice genotypes and three check verities that were evaluated at Crop Research Station Masodha under the supervision ANDUAT, Ayodhya from July to November 2019 to estimate genetic variability, heritability and genetic advance for grain yield and 12 yield associated traits.
