A field experiment was conducted during kharif, 2019 at College Farm, Professor Jayashankar Telangana State Agricultural University, Telangana. The present study was conducted to know the effect of different planting densities and nitrogen levels on the growth and yield of Finger millet. The soil of experimental site was loamy sand type, slightly acidic in pH (6.43), non-saline in EC (0.15 dSm-1), low in organic carbon (0.42%), low in available N (201.6 kg ha-1), medium in available P (25.3 kg ha-1), low in available K (236.25 kg ha-1). The experiment was laid out in randomized block design with factorial concept and replicated thrice with 12 treatments combinations consisting of four nitrogen levels (0 %, 50%, 100% and 150% RDN) and three levels of planting density (S1-solid rows × 15 cm, S2- 30 cm × 15 cm, S3- 25 cm × 15 cm). Results indicated that S1-solid rows × 15 cm recorded highest plant height, number of tillers m-2, dry matter production (g m-2) and S3- 25 cm × 15 cm recorded highest leaf area plant-1 and yield. Application of 150% RDN recorded highest plant growth parameters, grain yield and straw yield. However, it was on par with 100% RDN. It was concluded that planting density of 25 cm × 15 cm among spacings and 100% N among nitrogen levels proved to be a viable option for getting higher productivity and profit under rainfed conditions of central agro climatic zone of Telangana.

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.

Irrigation associated to reduction on planting spaces between rows and between coffee plants has been a featured practice in coffee cultivation. The objective of the present study was to assess, over a period of five consecutive years, influence of different irrigation management regimes and planting densities on growth and bean yield of Coffea arabica L.. The treatments consisted of four irrigation regimes: climatologic water balance, irrigation when the soil water tension reached values close to 20 and 60 kPa; and a control that was not irrigated. The treatments were distributed randomly in five planting densities: 2,500, 3,333, 5,000, 10,000 and 20,000 plants ha-1. A split-plot in randomized block design was used with four replications. Irrigation promoted better growth of coffee plants and increased yield that varied in function of the plant density per area. For densities from 10,000 to 20,000 plants ha-1, regardless of the used irrigation management, mean yield increases were over 49.6% compared to the non-irrigated crop.

Zucchini (Cucurbita pepo L.) is a horticultural crop of great socioeconomic importance in Brazil and in the world. However, inappropriate fertilization management, such as over-fertilization of soils, may become a limiting factor for its development. Thus, the aim of this study was to evaluate the morpho-physiological behavior of zucchini submitted to nitrogen (N) doses applied via soil and foliar application of silicon (Si). The treatments were distributed in split-plot scheme in a randomized block design, with three replications. The plot was formed by silicon levels (0.0 and 6.0 g plant-1) and the subplots constituted by five nitrogen levels (30, 60, 90, 120 and 150 kg ha-1), adding up to 30 experimental units. Gas exchanges and growth parameters were assessed at 35 days after planting. The data were submitted to analysis of variance by the F test and in the cases of significance was performed a polynomial regression analysis for the nitrogen factor and Tukey test for the silicon factor. The supply of Si positively enhances the effects of N on growth characteristics and gas exchanges of zucchini. The simultaneous application of Si and N does not influence the leaf area of zucchini. The N dose of 93.9 kg ha-1 provides greater assimilation of CO2 in zucchini plants under the conditions in which the experiment was performed.

A field trial was conducted at the Experimental Farm of the University of Benin, Benin City, Nigeria between May and July in both 2015 and 2016 to evaluate growth and yield responses of cucumber (Cucumis sativum L.) to different nitrogen levels of goat manure. The experiment was laid out in a randomized complete block design involving five treatments and replicated three times. The treatments were cured goat manure applied at levels of 0, 100, 200, 300 and 400 kg N ha-1. Growth parameters were collected on vine length (cm), vine girth (cm), number of branches, number of leaves and leaf area index (LAI). Yield parameters assessed were fruit length (cm), fruit girth (cm), number of fruits per plant and fruit yield (t ha-1). Goat manure application significantly (P < 0.05) influenced growth parameters positively, which led to the enhancement of the fruit yield. Goat manure application levels of 200 (20.85 t ha-1), 300 (20.85 t ha-1) and 400 (26.21 t ha-1) kg N ha-1 had similar (P > 0.05) fruit yield, but significantly (P < 0.05) higher than those of 0 (12.34 t ha-1) and 10 (16.96 t ha-1) kg N ha-1. It thus recommended that goat manure at 20 kg N ha-1 is more appropriate for cucumber production in the humid ultisols environment.

An experiment consisting of four phosphorus levels (0, 40, 60 and 80 kg/ha P2O5) and five zinc levels (0, 10, 20, 30 and 40 kg/ha ZnSO4) was laid out in randomized block design in factorial mode to find out the effect on yield and quality of fodder cowpea [Vigna Unguiculata (L.)Walp.]. Growth parameters viz. plant height, number of leaves, number of branches, leaf length, leaf width and leaf stem ratio were improved with the application of 60 kg/ha P2O5 and 20 kg/ha ZnSO4. Application of 60 kg/ha phosphorus recorded 27.64 t/ha yield, which was 7.50 and 55.6 % higher than 40 kg/ha and no phosphorus application, respectively. Application of zinc in the form of ZnSO4 @ 20 kg/ha increased significantly the green fodder yield (25.89 t/ha). Interaction effect of phosphorus and zinc application was found significant with respect to green fodder, dry matter yield and nutrient uptake. Yield, phosphorus and zinc uptake in cowpea fodder were showing declining trend at combination of application rate more than 60 kg/ha P2O5 and 20 kg/ha ZnSO4.

A field experiment was conducted at Nalanda College of Horticulture, Noorsarai, Nalanda during summer 2017 to assess the effect of complementary and sole applications of organic and inorganic fertilizers on the growth and yield of bottle gourd under onion-onion-bottle gourd crop sequence. The experiment consists of seven treatments viz.,T1-Inorganic fertilizers (120 Kg N: 60 Kg P2O5 and 40 Kg K2O); T2-50% NPK through inorganic fertilizer + 50%N through FYM; T3-50% N through FYM + 50% N through VC; T4-1/3 of N through FYM + VC + Neemcake; T5-50% N through FYM + PSB + Azotobactor; T6-T3 + PSB + Azotobactor and T7-T4 + PSB + Azotobactor. These seven treatments were replicated thrice in Randomized Block Design. Results revealed that T1-100% NPK through inorganic fertilizer recorded 225.7 q ha-1 fruit yield, which was statistically at par with T2 and T6 producing (211.8 and 209.5 q ha-1). Vine length differed significantly at all the growth stages. T1 recorded maximum vine length (51.8, 370.3 and 464.7 cm) at 30, 60 and 90 DAS, which was significantly higher over T5 at 30 DAS, over T4 and T5 at 60 DAS and over T5 at 90 DAS. Among organics, T6 recorded longest vine, while T5 recorded shortest. No. of branches were found non-significant at 30 DAS but it become significant at 60 and 90 DAS and found significantly highest in T6 over all the treatments. After completion of the cropping system; onion-onion-bottle gourd, soils were subjected to analysis. pH differed significantly, while non-significant difference were observed in EC and soil Org-C. Similarly, available N and P concentration were also found non-significant due to different fertilizer sources, but the concentration of available K differed significantly and found highest in T1 which was at par with T2. T1-100% inorganic fertilizer sources recorded highest gross return, net return and B: C ratio followed by T2. On the basis of result it has been concluded that T2 having 50% NPK through inorganic fertilizer + 50% N through FYM may found suitable for sustainable bottle gourd production as it performed at par with T1 in respect to crop growth and yield.

O experimento foi desenvolvido no campo experimental da Embrapa Mandioca e Fruticultura Tropical, em Cruz das Almas, Bahia, no delineamento em blocos casualizados, com cinco tratamentos e cinco repetições. Foram obtidos dados biométricos (altura de planta, diâmetro de caule e área foliar) e de produção. Não houve diferença significativa entre as médias de crescimento e produtividade do mamoeiro nos diversos tratamentos, indicando não haver diferença entre as fontes nítrica e amoniacal para fertirrigação. A substituição do sulfato de amônio por nitrato de cálcio como única fonte nitrogenada para o mamoeiro promoveu um ganho de produtividade de 14,79%, elevando, porém, o custo de produção em 649,84%. A aplicação de nitrogênio ao solo no período de 12 meses, considerando 50% do período com sulfato de amônio e 50% com de nitrato de cálcio, não causou acidificação ou aumento do pH do solo. UNITERMOS: Fertirrigação, parâmetros biométricos, produtividade.  SOUZA, T.

Planting potatoes in the tropical lowlands as an effort to reduce the adverse effects of planting in the highlands such as erosion, pests and plant diseases has been carried out and the tubers have been successfully obtained. Planting of potato seeds was carried out with an aeroponic system and climate modification in the root zone cooling environment. Climate modification is carried out at an altitude of 250 m asl and <125 m asl. The stability of the temperature in the aeroponic chamber can be maintained by regulating the time of spraying cold nutrients through the nozzles to the root area. However, the importance of the time to provide nutrition in order to maintain the optimal temperature of the root area in aeroponic systems in the lowlands has not been widely reported scientifically. The purpose of this study was to obtain the appropriate time for nutrition in order to maintain optimal chamber temperature and to have an effect on the growth and yield of potato seeds. The research was conducted in the greenhouse of the Faculty of Agriculture, Jenderal Soedirman University, Purwokerto, Central Java, Indonesia. Height of place <125 m above sea level. The study was conducted from July to September 2017. The factors that were tried in the study were as follows: 1. Length of time for nutrition (T): T1: 2.5 minutes OFF and 15 minutes ON; T2: 5 minutes OFF, 15 minutes ON, T3: 10 minutes OFF, 15 minutes ON, T4: 15 minutes OFF, 15 minutes ON, 2. Varieties (V): V1 (Atlantic), V2 (Granola). Growth parameters observed: plant height, number of leaves, number of tubers, tuber weight. Experiment using a randomized block design with 3 replications. The data were analyzed by F test and continued with Duncan’s Multiple Range Testof 5% level.The results showed that the duration of nutrient administration by setting a timer gave different results on the growth and development of aeroponic plants of potato seeds in the lowlands 125 m above sea level.
