An experiment was conducted at the Regional Research Station , Uchani (Karnal) of CCS Haryana Agricultural University, Hisar, India during 2020-21 to assess the effect of the method and schedule of fertilizer application on macronutrient status viz. available Nitrogen (N), Phosphorus (P) and potassium(K) and soil chemical properties i.e. soil pH, electrical conductivity (EC) and soil organic carbon (SOC) at different intervals of the crop growth period. The experiment was laid out in split plot design with two methods of fertilizer application (B1-broadcasting and B2- band placement) as main plot treatments and four sub plot treatments consisting of the application of recommended doses of N and K fertilizer (RDF) in the different number of splits at different number of days after planting (DAP) i.e. T1(five splits), T2(six splits), T3(seven splits) and T4(three splits). Results elucidated that the availability of all the macronutrients was significantly affected by both sub and m...

Field experiments were conducted for three crop seasons of 2001-02, 2002-03 and 2003-04 (planted in spring season), in order to find out the effect of fertility levels (nitrogen and phosphorus) on yield and quality of newly developed early and mid –late maturing sugarcane varieties of North-West Zone of the country under All India Coordinated Research Project on sugarcane. Early maturing variety CoS 96258 proved significantly superior to other two early maturing varieties namely CoLk 9414 and CoJ 96191, the later two being statistically at par in respect of cane yield. Amongst the mid-late maturing varieties, CoS 93278 proved significantly superior over variety CoH 119, which in turn proved significantly superior to variety CoH 110 in respect of cane yield. There was significant increase in cane yield of early maturing varieties due to increasing doses of nitrogen and phosphorus from 75% to 125% of recommendation, but this increase was significant only upto 100% of recommended doses of nitrogen and phosphorus in case of mid –late maturing varieties. Though, there was non- significant effect of varieties and fertility levels on CCS percentage, but the production of commercial cane sugar (t/ha) varied considerably according to cane yield of varieties and influence of fertility levels.

A field experiment was conduced during 2000–03 and 2001–04 to evolve suitable and economical integrated weed-management technologies for sugarcane (Saccharum officinarum) plant and ratoon crops. The treatments comprised four different weed-management practices for plant (chemical, integrated, interculture and weedy check) and ratoon (integrated, trash mulching, interculture and weedy check). In plant crop the integrated method (one hoeing after first irrigation followed by spraying of atrazine 2 kg/ha after second irrigation in moist soil) and in ratoon crop the integrated method (one hoeing followed by spraying of atrazine 2 kg/ha in moist soil at ratoon-initiation stage) or trash mulching were observed to be better weed-management technologies for cane production, involving less costs. Rice-mustard-sugarcane (plant)-ratoon-wheat cropping system was found more economical than rice-wheat-sugarcane (plant)-ratoon-wheat cropping system.

Present investigation was carried out at Regional Research Station, Uchani (Karnal) of CCS Haryana Agricultural University, Hisar, India during 2020-21 to assess the effect of method and schedule of fertilizer application on growth, yield attributes and cane yield of summer planted sugarcane (Saccharum officinarum L.) crop under wide spacing (120 cm). The experiment was arranged in split plot design with two methods of fertilizer application (B1-broadcasting and B2- band placement) as main plot treatments and four sub plot treatments which include application of recommended dose of N and K fertilizer (RDF) in different number of splits at different no. of days after planting (DAP) i.e. T1 (five splits), T2 (six splits), T3 (seven splits) and T4 (three splits). Results concluded that majority of growth parameters, yield attributes and cane yield were significantly affected by both main and sub plot treatments at different stages of crop growth period. Treatment B2 registered signific...

A split plot experiment was conducted at Regional Research Station, CCS HAU, Uchani, Karnal during 2014–15 and 2015–16 to investigate the effect of different soil moisture regimes on antioxidative defense mechanism of sugarcane (Saccharum officinarum L.) varieties. The experiment consisted of three moisture regimes based on available soil moisture i.e. irrigation at 50% ASM, 40% ASM and 30% ASM in main plot and four commercial sugarcane varieties, i.e. CoS 767, CoH 128, CoJ 64 and Co 0238 in sub plot with three replications. The observations recorded on antioxidative defense system have suggested possible key characteristics of drought tolerance. Low ASM levels induced the antioxidative defense system by increasing ROS and the specific activities of antioxidative enzymes, viz. peroxidase, catalase and ascorbate peroxidase. Specific activity of these enzymes increased in varieties Co 0238 and CoS 767 at 60 and 90 DAP. Severe stress of 30% ASM levels also resulted in a sharp rise in t...

Man has been aware of honey bees since ages as reflected from depictions and inscriptions made around 10,000 years ago. North America and Egypt were the early starters in Bee-keeping. Discovery on the phenomenon of division of labor, life cycle and rearing techniques in different countries led to the successful domestication. Honey bees gain importance by pollination of flowering plants and it has been estimated that global value of pollination is around 153 billion dollars annually. Considering the economics, an income to the tune of Rs. 3,500.00 - 7,000.00 per hive can be achieved annually. At present India has got 2.0 million bee colonies but has the potential to keep around 120 million bee colonies that can provide employment to 12 million families.

A field experiment was conducted during spring season of 2014–15 and 2015–16 at CCS HAU, RRS, Karnal to evaluate the response of four sugarcane (Saccharum officinarum L.) varieties differing in their maturity i.e. CoS 767 (Mid late), CoH128 (Mid late), CoJ 64 (Early) and Co 0238 (Early) to deficit irrigation. The experiment was conducted in split plot design with three replications. Based on available soil moisture (ASM), three treatments i.e. irrigation at 50% ASM (control), 40% ASM (mild stress) and 30% ASM (severe stress) were imposed in main plot and sugarcane varieties in sub-plot. Under deficit irrigation, leaf area, leaf area index (LAI), crop grown rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR), significantly, reduced at 30–60 and 60–90 DAP in all the varieties and the varieties Co 0238 and CoS 767 showed least reduction. The yield parameters, viz. number of millable canes, cane length, internodal length and single cane weight reduced significantly un...

Physiological and biochemical changes in response to deficit irrigation (drought stress) were studied at three moisture regimes based on available soil moisture (ASM) and four commercial sugarcane varieties differing in their maturity i.e. CoS 767 (Mid late), CoH128 (Mid late), CoJ 64 (Early) and Co 0238 (Early) Plant water status was affected significantly with duration and severity of stress with maximum reduction at 30% ASM level at 90 DAP. The water potential (from 0.62 to 1.16 MPa), osmotic potential (from 0.88 to 1.77 MPa) and relative water content (from 87.59 to 65.51%) decreased significantly at 30% ASM level than at 50% ASM in all the varieties. After stress revival, a remarkable recovery was recorded in all the varieties at all the ASM levels with maximum recovery in varieties Co 0238 and CoS 767. Higher membrane injury was recorded in CoJ 64 followed by CoH 128, Co 0238 and CoS 767at 30% ASM at 60 and 90 DAP. Remarkable decrease were observed in gaseous exchange para...
