A field experiment was conducted at Research and Advanced Studies, Dhablan, Department of Agriculture, Khalsa College, Patiala during rabiseason 2019-20 to find out the influence of plant densities and fertility levels on growth and yield of chickpea (Cicer arietinum L.) genotypes. The experiment was conducted in factorial randomized block design and replicated thrice. The experiment consisted of two genotypes (PBG 7 and GPF 2), two planting densities and two fertility levels. The results revealed that the genotype PBG 7 recorded significantly highestgrain yield (18.01 q ha-1) as compared to genotype GPF2 (16.62 q ha-1). The growth parameters were also higher with genotype PBG 7 followed by GPF 2. The density of 30 × 10 cm recorded. The highest grain and straw yield (17.47 and 22.51 q ha-1)as compared to 45× 10 cm spacing (16.74 and 18.53 q ha-1). However, yield attributes like pods plant-1,grain yield plant-1 and harvest index were higher with wider planting density (45 × 10 cm). Higher fertility level (N30P60K30S20 kg ha-1) produced highest grain yield (17.88 q ha-1) as compared to low fertility levels(16.75 q ha-1). The growth and yield parameters followed the similar trend. The chickpea genotype PBG 7 showed better response to closer planting density and higher fertility level.

Soybean genotypes grown in sub-tropical climate may exhibit lodging. The plant lodging is influenced by soil type and fertility level, sowing date, latitude and altitude of the location, plant population and conditions of crop development. Plant regulators and herbicides are able to avoid or reduce plant lodging. This study aimed to verify the effects of the growth regulators TIBA and daminozide on vegetative growth and yield of soybean cultivar CD 214 RR. The experiment was carried out at a field in randomized block design with four replications in a factorial scheme. The A factor was represented by the combination of regulators TIBA and daminozide and its concentrations, and the Factor B was seven times of evaluation of injury and plant height or eight times of evaluation of lodging. In the range of doses used, the application of daminozide resulted in greater injury to soybean plants than TIBA. The smaller plant height was achieved by the application of 6 g ha-1 of TIBA and 1200 g ha-¹ of daminozide. Treatments with daminozide (100 g ha-¹) and TIBA (10 g ha-1) stood out due to the reduced lodging of soybean plants. Grain weight increased linearly when the levels of TIBA increased. There was a negative correlation between lodging and grain yield and a positive correlation between plant height and lodging. There was also a negative correlation between injury caused by the application of plant regulators and lodging.

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.

ABSTRACT Castor bean is an important raw material to produce biofuel in Brazil and can be grown in several regions of the country due to its good adaptation and tolerance to high temperatures and water deficit. The objective of this study was to evaluate the productivity of castor bean plants intercropped at different plant densities with Urochloa ruziziensis. The experiment was conducted in a randomized block design with four replications, using a 4 × 2 factorial arrangement, consisting of four plant densities (13,574, 24,512, 36,816, and 40,723 plants ha-1) of castor bean and two crop systems (single crop, and intercrop with Urochloa ruziziensis). The data were subjected to analyses of variance and regression, and means were compared by the Tukey’s test (p < 0.05). The intercrop system reduced the number of pods per plant by 15%, but it did not significantly affect the castor bean grain yield. Increasing plant density reduced linearly the proportion of plants harvested, reaching 22.1%, from the lowest to the highest plant density used; the highest grain yield was achieved using 36,816 plants ha-1 for both intercrop and single crop systems. Intercropping castor bean with U. ruziziensis does not reduce the castor bean grain yield and is an alternative to produce biomass for following crops, especially in production environments with low fertility soils, high temperatures, and infrequent rainfall.

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.

Background: Blackgram [Vigna mungo (L.) Hepper] is one of the most important cultivated legume crops with high nutritive value and agricultural importance. The productivity of blackgram is not adequate to meet the domestic demand of the growing Indian population. Consequently, there is an urgent need for enhancement of productivity through proper agronomic practices. With this background, a research experiment was conducted in a farmer’s field at Pudhupalayam, Coimbatore to investigate the effect of foliar application of PPFM, plant growth regulating compounds and nutrients on growth, yield attributes, yield and economics of irrigated blackgram. Methods: A field experiment was laid out in randomized block design with three replications during 2019 (kharif and rabi) season. The treatments include 100% recommended dose of NPK along with foliar application of diammonium phosphate (DAP), brassinolide (Br), salicylic acid (SA) and pink pigmented facultative methylotrophs (PPFM) with different concentration (1%, 2%, 1 ppm, 2 ppm, 50 ppm, 100 ppm, respectively) in addition to control. PPFM and PGRs were sprayed at 30 and 45 days after the sowing of blackgram. Result: The experiment results of the two seasons study revealed that the application of 100% RDF + PPFM @ 2% recorded higher growth characters viz., plant height (cm), number of branches plant-1, leaf area index and yield attributes viz., number of pods plant-1, number of seeds pod-1, pod weight (g), pod height (cm), 100 seed weight (g) and yield viz., grain yield (kg/ha), straw yield (kg/ha) and harvest index (%). As well as the same treatment recorded higher net return and B:C ratio. Correlation and regression analysis also indicated that the yield attributes had a positive impact on the grain yield with a magnitude of 1.91 and 1.67, respectively. Therefore, application of 100% RDF+2% PPFM spray can be recommended as the best technology to improve the yield and economics of blackgram.

The aim of this study was to evaluate the influence of planting density and cultivar of soybean on yield components in the southeast Amazon. The experiment was carried out in an Oxisol, with a randomized block design in a 2 x 4 factorial scheme. The treatments were two soybean cultivars (BRS 9090 RR and BRS 8990 RR) and four planting densities (13, 15, 18 and 20 plants m-1), with three replications. First pod insertion height (IFP), plant height (H), number of pods per plant (NPP), grain yield (Y) and weight of 100 grains (W100) were evaluated. The insertion height of the first pod showed a tendency of increase with the increment of plants per linear meter for cultivar BRS 8990 RR, different of the behavior observed for the cultivar BRS 9090 RR, which only showed difference when the density of 300.000 plants ha-1 was tested. For plant height, among soybean cultivars, there was only difference in D400, with BRS 8990 RR showing a maximum height of 83.3 cm, 21% higher than BRS 9090 RR. When evaluated under D350, BRS 8990 RR showed an increase of 13% in the number of pods compared to BRS 9090 RR. Both cultivars showed linear behavior for the grain yield, increasing according the plant population, with the highest grain yield obtained under the density of 400.000 plants ha-1 (4527.3 kg ha-1). The weight of 100 grains was not influenced by any variation factor.

The experiment was conducted at the Bangladesh Institute of Nuclear Agriculture (BINA) sub-staion, Tajhat, Ranpure, using potato-Boro-T. aman rice cropping pattern with an objective to evaluate the direct and residual effects of sulphur and zinc on the growth, yield and nutrient uptake by the crops. The surface soil was sandy loam texture, pH 6.3, organic matter 1.24%, available sulphur 6.62 ppm and available zinc 0.45 ppm. The experiment comprised of eight treatments for potato S15Zn2 (T2, T4 and T8, S8Zn1 (T5 and T6)and S0Zn0 (T1, T3 and T7), for boro rice S20Zn4 (T3, T5, T6 and T7) and S0Zn0 (T1, T3, T4 and T6). The experiment was laid out in a randomized complete block design with three replications. Average tuber yield of potato (var. cardinal) varied from 28.29 to 32.86 t ha-1 with the highest yield in S15Zn2 treatment (100% recommended dose) and the lowest was in the S0Zn0 treatment (control). In the second crop (Boro rice), growth and yield attributes, grain and straw yields responded significantly to S and Zn applied either in the first crop or in both crops. The average grain yield varied from 3.51 to 5.27 t ha-1 over the treatments. In the third crop (T. aman rice), the grain and straw yields responded significantly to S and Zn applied either in the first and second crop or in the third crops. The grain yield of T. aman rice varied from 2.96 to 4.46 t ha-1 over the treatments. The growth and yield contributing characters were also significantly influenced by the treatment. There was a significant direct and residual effect of the treatments on S and Zn uptake by the crops.DOI: http://dx.doi.org/10.3329/pa.v19i1.16987 Progress. Agric. 19(1): 33 - 38, 2008

A pot experiment was conducted at the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh during the period of November, 2017 to March, 2018 to optimize different levels of Zn and B for better growth and yield attributes of tomato (cv. Ruma VF). The experiment included two factors [factor- A viz., control (Zn0 ), Zn @ 4.0 kg ha-1 (Zn4),  Zn @ 6.0 kg ha-1 (Zn6) and Zn @ 8.0 kg ha-1 (Zn8) and factor B viz., control (B0), B @ 2.0 kg ha-1 (B2) and B @ 3.0 kg ha-1 (B3)], which was laid out in a completely randomized block design with 4 replications, thus total number of pots were 48. Zinc sulphate and boric acid were applied as the source of Zn and B that were applied during pot preparation along with recommended doses of N, P, K and S. The study revealed that application of different doses of Zn increased number of flower clusters plant-1 at 80 days after transplanting, fruit length, fruit diameter, number of fruits plant-1 and yield of tomato up to 4.0 kg ha-1. Similarly, application of B @ 2.0 kg ha-1 produced the highest number of flower clusters plant-1, fruit length and fruit diameter. On the other hand, the highest number of fruits plant-1 and yield of tomato were obtained by the application of B @ 3.0 kg ha-1 which was statistically similar to the application of B @ 2.0 kg ha-1. Combined application of Zn and B, @ 4.0 and 2.0 kg ha-1, respectively appeared as the best practice for better growth and yield of tomato, and therefore it may be recommended to boost up tomato productivity.

A field experiment was conducted during kharif season of 2015 on silty clay loam soil at MPKV, Rahuri (MS), to study the varying nutrient management levels on productivity and economics of different soybean varieties. The experiment was laid out in factorial randomized block design with 15 combinations of three varieties (KDS-344, JS-9305 and KS-103) and five nutrient management levels ( GRDF, 75% GRDF + 0.5% foliar spray of grade IInd at 30 and 45 DAS, 100% GRDF + 0.5% foliar spray of grade IInd at 30 and 45 DAS, N4: 125% GRDF + 0.5% foliar spray of grade IInd at 30 and 45 DAS and 50:75:30 N, P2O5, K2O kg ha-1 + 5 tons FYM ha-1. The variety KDS-344 and application of nutrient management dose 125% GRDF + 0.5 Grade IInd foliar spray at 30 and 45 DAS recorded significantly the highest growth and yield attributes viz., plant height (cm), number of branches, number root of nodules, number of pod plant-1 and weight of seeds plant-1 (g). The variety KDS-344 recorded highest grain and stover (3.66 and 4.64 t /ha) yield and highest economic indices like cost of cultivation (40,623), net monetary returns (87355) and net returns per rupee invested (3.17). The grain yield (4.34 t/ha) and stover yield (4.53 t/ha) of soybean was significantly higher by application of fertilizer dose of 125% GRDF + 0.5% Grade IInd foliar spray at 30 and 45 DAS than rest of treatments, but it was also at par with 75% GRDF + 0.5 Grade IInd foliar spray at 30 and 45 DAS and 100% GRDF + 0.5% Grade IInd foliar spray at 30 and 45 DAS. Similarly, variety KDS-344 and application of nutrient levels of 75 % GRDF + 0.5 % Grade IInd foliar spray at 30 and 45 DAS recorded the highest net returns (82756) and net returns per rupee invested (3.24) in soybean due to reduce in cost of cultivation (36931) and nutrient losses.
