ABSTRACT: Grasshoppers of the families Acrididae and Romaleidae (Orthoptera) are among the insects that defoliate heliconias and have been gaining status as pests of commercial crops of these plants in Brazil. The objectives of the present study were to identify the grasshopper defoliating heliconias in the municipality of Santo Antônio de Pádua, RJ (Brazil), to evaluate the effect of different levels of shade on the population of this grasshopper and the production parameters of heliconias, and to determine if this grasshopper has an oviposition preference among the heliconias evaluated. The experiment was in a completely randomized block design, in subdivided plots (four levels of shade in the plot, 0%, 30%, 50% and 80%, and four species of Heliconia: H. psittacorum, H. stricta, H. wagneriana and H. psittacorum x H. spathocircinata ‘Golden Torch’ in the subplot), with four replications. The grasshopper was identified as Cornops frenatum frenatum (Acrididae). An increase in shade resulted in a decrease in the number of oviposition holes from the grasshopper and the number of lateral buds. Shade did not influence the number of C. f. frenatum nymphs and adults and the number of flower stems. H. wagneriana was the most preferred species for oviposition by C. f. frenatum. Results suggested using screens to shade heliconia plants can help control C. f. frenatum populations, however, the light requirements of the heliconias should be considered to guarantee productivity.

The availability of micronutrients in the niche defines the growth and yield parameters of chickpea. The present study was conducted to investigate the effect of different levels of biofertilizer with and without molybdenum on growth and seed yield of chickpea, at Seed Production Block, SGRR University, Dehradun, Uttarakhand. The experiment included seven treatment groups replicated thrice in Randomized Block Design. It was observed that all growth and seed yield parameters varied significantly with the application of different levels of biofertilizers with or without molybdenum. The observed results showed that all the plant growth parameters like plant height (54.67 cm), number of primary branches (5.34/ plant), number of pods per plants (64.00), fresh weight of plant (81.66 g) were maximum with treatment T6 (20 g Rhizobium+25 g PSB +0.3 g molybdenum/kg seeds). The number of nodules per plant (28.00) and 1000 seed weight (142 g) were recorded maximum with the application of treatment T7 (25 g Rhizobium + 30 g PSB + 0.3 g molybdenum per kg of seeds). The seed yield of chickpea was recorded maximum (15.67 q/ha) with the application of 20 g Rhizobium along with 25 g PSB and 0.3 g molybdenum per kg of seeds (T6). Thus, our findings indicate that, among all other treatments, the application of 20 g Rhizobium along with 25 g PSB and 0.3 g molybdenum per kg of seeds is suitable for higher seed yield of chickpea in Doon valley of Uttarakhand.

The experiment was carried out to evaluate the effect of different levels of dried slurry (DS) as source of nitrogen fertilizer on yield and chemical composition of maize fodder (Zea mays). Four levels of DS (0, 10, 12 and 14 ton/ha) were applied in a Randomized Block Design (RBD). Green biomass yields was significantly higher in DS incorporated groups compared to control. The highest (P<0.01) biomass yield was observed at the application of 12 ton DS/ha. Application of 12 ton DS/ha resulted highest plant height, number of leaves and leaves area (cm2) and stem circumference of maize fodder (P<0.01). Dry matter (DM) and crude protein (CP) content of maize fodder was increased (P<0.01) with an application of 12 ton DS/ha while acid detergent fiber (ADF) and total ash contents were decreased with an increased level of DS. Organic matter (OM) and neutral detergent fiber (NDF) content of green grass were non significant for the incorporation of different levels of DS. From the results of the present study it is evident that, maize fodder can be cultivated through the application of 12 ton DS/ha for obtaining higher yield and nutrient content.

Studies were made on the fodder and seed production of ryegrass (Lolium perenne L.) using twelve treatment combinations with four levels of nitrogen (30, 60, 90 and 120 kg/ha/cut) and three levels of phosphorus (0, 50 and 100 kg P2O5/ha), laid out in a randomized block design with four replications. The mean of two years indicated that nitrogen at 120 kg/ha/cut increased the green fodder (834 q/ha) and dry matter yield (129 q/ha) significantly over the lower doses. After leaving the same crop for seed production during mid-March, nitrogen at the rate of 60 kg/ha gave the highest seed yield (7.61 q/ha). Beyond this dose the seed yield decreased drastically due to lodging. Phosphorus at the rate of 50 kg P2O5/ha gave 5% higher dry matter (99.6 q/ha) and 7.4% higher seed yield (7.26 q/ha) over the control.

Effect of nitrogen and bio-fertilizer on growth and productivity of hybrid rice (cv. PHB 71) was assessed during dry seasons of 2017 and 2018 at Research Farm of BCKV under new alluvial zone of West Bengal. The experiment was laid out in factorial randomized block design with 12 treatment combinations having 4 levels of N and 3 types of bio-fertilizer replicated thrice. Application at 180 kg N/ha produced tallest plants at 90 DAT with maximum LAI (60 DAT), DMA (90 DAT), tillers/hill (90 DAT) and CGR (30-60 & 60-90 DAT). The same N rate resulted in highest panicles/m2, panicle length, panicle weight, filled grains/panicle and 1000-grain weight. A decrease in N dose from 180 to 150 kg/ha caused reduction in all those yield components; however, the variation was non-significant except for number of panicles/m2. Maximum grain yield, straw yield and harvest index was also achieved with 180 kg N/ha accounting 120.1, 34.9 and 32.8% more than the values obtained with zero-N; however, it was statistically at par with the yields and HI obtained with 150 kg N/ha. The Azospirillum application increased all the growth parameters, yield components and yield of hybrid rice over other tested bio-fertilizers (Azospirillum > PSB > K mobilizer), accounting 5.9 and 8.8% more than the yields obtained with PSB and K mobilizer. The interaction of N and bio-fertilizer exerted significant effect on growth attributes but failed to record any significant variations in yield components and yield of hybrid rice. The maximum economic benefit was achieved with combined application of 180 kg N/ha and Azospirillum.

A study was conducted to assess the effect of drip irrigation and plastic mulch on growth and seed yield of Semialata. Two types of plastic mulch (green and silver/black) were tested at three levels of irrigation (120%, 100% and 80%) by drip irrigation and one level (100%) by furrow irrigation. The daily water requirement of Semialata was estimated by the equation ETcrop= ETox crop factor. ETcrop is crop water requirement mm/day. ETo (reference evapotranspiration, mm/day) was calculated by FAO calculator which uses temperature and humidity data. In this experiments there were twelve treatments were considered. The treatments were replicated thrice. The experiment was laid in randomized block design. It was observed that drip irrigation with or without plastic mulch is yielding better results in terms of growth parameters and seed yield as compared to furrow irrigation without plastic mulch. It was also observed that maximum suppression (67.58%) of weeds resulted with drip irrigation and silver/black plastic mulch at 80% level of irrigation.
