Field experiments were conducted during 1999-2000 and 2000-2001 to study the effect of basal application (BA) of zinc sulphate (5 and 10 mg kg-i soil) or boric acid (1 and 2 mg kg-1 soil) alone or foliar applications (FA) of water or 1% ZnSO4 or 1% H3 B03 or the combinations of both BA and FA of either ZnSO4 or H3 B03 on yield attributes (number of flowers and fruits/ plant, fruit weight, size and total yield). On the basis of the two-year data, it was found that all the treatments of BA as well as FA enhanced yield attributes but the combination of BA of 10 mg kg--1 soil ZnSO4 and FA of 1% H3 B03 gave highest yield as compared to other treatments and control plants.

A field experiment was conducted at KVK Kalyan instructional farm at Jahajpur of Purulia district of West Bengal during rabi season of 2018-19 to assess the effect of Biochar and Vermicompost as organic soil amendments on yield of brinjal under red and lateritic soils of Purulia, West Bengal. Biochar and vermicompost applied alone additionally in the farmers practice. The experiment design adopted was Randomised Block Design (RBD) having four replications with three treatments The treatments comprises of T1: Application of N:P:K  70:30:30 kg/ha (Farmers’ practice) + FYM @ 2 t/ha, T2: Farmers practice  + Vermicompost @ 5 t/ha, T3: Farmers practice  + Biochar @ 10 t/ha. The growth and yield attributing characters recorded was plant height at 30, 60, 90 and 120 DAT, number of fruits per plant, average fruit weight, yield per plant and total yield. Application of biochar and vermicompost had a significant effect on the growth and yield of Brinjal. Highest growth yield attributes and highest fruit yield (22.36 t/ha) were obtained due to the application of farmers practice + vermicompost @ 5 t/ha (T2). Application of biochar along with farmers’ practice did not show any significant results in brinjal yield as compare to vermicompost application treatment. The potential for long-term benefits of biochar remain to be explored through continued research in the red laterite soils of Purulia district of West Bengal.

Field experiments were conducted to a) maximize total yield of fresh-market field tomato (Lycopersicon esculentum Mill.) cultivars using black polyethylene mulch (BPM), and b) increase fruit size and yield during the last 5 weeks of the production period by reducing the number of synthate sinks per plant through eliminating all flowers that appeared during this period. Unmulched treatments under trickle irrigation and multiple applications of soluble fertilizer yielded an average of 43 t·ha-1 for `Sunny' and `Pik-Rite' over the two planting dates. With BPM, total yield increased by 95% to 84 t·ha-1. Although total yield increases due to BPM over the control were highly significant in both cultivars and over the two planting dates, yield increases were higher for the early than for the optimum planting date. BPM also significantly increased early production of `Pik-Rite' but not `Sunny', and the increase in early production was more pronounced for the optimum than the early planting date. Sink reduction during the last 5 weeks of the growing season had no effect on yield or fruit weight during that period.

Twenty two brinjal (Solanum melongena L.) genotypes were collected and grown in summer season and variability estimates were studied for twenty two different quality, yield, its attributing traits. High genotypic and phenotypic coefficient of variation was obtained for characters like length of style, fruit girth, average fruit weight, number of fruits per plant, yield per plant, total yield per hectare, total sugar, reducing sugar, titrable acidity, ascorbic acid, total antioxidant capacity, total phenolic content and polyphenol oxidase. Heritability and genetic gain as percent of mean was observed to be high for characters such as plant height, number of primary branches, length of style, fruit length, fruit girth, average fruit weight, number of fruit per plant, yield per plant, total yield per hectare, TSS, total sugar, reducing sugar, titrable acidity, ascorbic acid, total antioxidant capacity, total phenolic content and polyphenol oxidase. High heritability coupled with high predicted genetic gain suggests for selection based on these traits for enhancement of yield and quality.

Abstract Chitosan is a natural heterogeneous polymer, non-toxic and find many potential applications in agriculture. The search of a biopolymer to replace the synthetic agrochemicals, the effects of foliar application of chitosan solution on agronomic performance under field experiments have been investigated in two consecutive harvests (2014/2015 and 2015) of soybean and maize. Two chitosan concentrations (0.5 and 1%) were sprayed four times during the culture development and the evaluation was based on morphological characteristics, growth and yield components. Seeds were collected to determine the content of macro- and micronutrients. Results revealed that most of the morphological and growth parameters (plant height, leaf number per plant) and yield attributes were not increased with the chitosan treatment in soybean and maize. The soybean treated with foliar application of chitosan 0.5% increased the accumulation of nitrogen by 9.14% when compared with the water treatment, but the effect was not consistent in both seasons and cultivars. The values of the other nutrients did not change the content. Maize plants treated with chitosan (0.5% or 1%) significantly decreased the boron concentration by 66.7% in the grains analyzed and may have influenced the plant development (height) without altering the other agronomic parameters. Therefore, whereas the climatic conditions in these two seasons were stable and biotic or abiotic stresses were not observed, foliar application of chitosan solution did not present differences that could establish a pattern of behavior in field experiments conducted by two harvests.

New Perspective

Consumer demands regarding eggplant fruits are focused on perfect shape, color, and taste but nutritional and bioactive quality has also become important with rising awareness of food related health. On the other hand, producers value modern cultivars’ earliness, high-yielding, stress-tolerance, and high overall fruit quality. We attempt to link these two standpoints through combining modern hybrids cultivated in the open field of temperate climatic zone with biostimulant application to increase the dynamics of yielding and the quality of fruits. The aim of our research was the determination of the genotypic-dependent response of eggplant (Solanum melongena L.) to Ascophyllum nodosum standardized extract (Göemar BM-86) application in field conditions of Poland, with respect to the most important characteristics linked to yield quality and plant stress status. The early and total yield of investigated hybrids was affected by biostimulant application, and this dependence was confirmed statistically for most of the treatments. The increase of ‘Epic’ F1 and ‘Flavine’ F1 yield potential through Göemar BM-86 application was linked to higher fruit number harvested from the plants, while ‘WA 6020’ F1 led to greater fruit weight. Investigated hybrids responded differently to biostimulant treatment with respect to dietary and pro-health value of fruits. Generally, the content of soluble sugar, anthocyanins, and mineral elements as well as was antioxidant activity of fruits were positively affected by biostimulant application. This tendency was statistically confirmed for several experimental treatments. Presented results give a new perspective on seaweed-based biostimulants as elicitors of crop’s self defense mechanisms as well as modulators of fruit setting, productivity and bioactive compounds accumulation in eggplant.   ********* In press - Online First.

The experiment was carried out during the spring and summer seasons of the year 2017-18 and 2018-19 at the Horticultural Research Farm, AAU, Anand to study the “Effect of soil and foliar applications of micronutrients on flowering and yield of mango variety”. The experimentcomprised of 13 treatments of different micronutrients application viz. FeSO4 100 g, ZnSO4 100 g, Borax 100 g and multimicronutrients grade-V 400 g as a soil application; FeSO4 0.5 %, ZnSO4 0.5 %, borax 0.2 % and multimicronutrients grade-IV 1.0 % as a foliar application and its combinassions and control (water spray). Soil application was done at second fortnight of September and foliar sprays of treatments were done at flower bud initiation, full bloom stage and pea stage initiationon 18 years old mango tree cv. Mallika. Experiment was laid out in a Completely Randomized Design (CRD) with three repetitions. Numbers of staminate, hermaphrodite and total number of flowers per panicle were found significant with respect to various micronutrients treatments during both the years of experiment. Maximum staminate flowers per panicle, hermaphrodite flowers per panicle and total number of flowers per panicle was found with soil application of multimicronutrients grade-V 400 g followed by foliar application of multimicronutrients grade-IV 1.0 % during both the years of study. The significantly higher number of fruits, average fruit weight and fruit yield per tree were recorded with soil application of multimicronutrients grade-V 400 g followed by foliar application of multimicronutrients grade-IV 1.0 % during the years 2017-18 and 2018-19.

Three field experiments were carried out in Lajas, Puerto Rico, to compare the effects of planting method (direct and transplant), plastic mulch (with and without), and planting density (1.8 x 1.8 m, 3.6 x 0.9 m, 1.8 x 0.9 m between and within rows) on production of short-and long-vined tropical pumpkins (Cucurbita moschata). The long-vine genotype produced greater yields and larger but fewer fruit than the short-vine genotype. However, most of the planting densities tested were probably not optimum for short-vine cultivars. Direct seeding of pumpkin was more efficient than transplanting and resulted in the same early and total yield as transplanting. Yields with plastic-covered banks were similar to yields without the use of plastic. However, use of plastic mulch increased the number of fruit and decreased the average fruit weight in the plots. The best planting distance depended on the type of genotype used. The long-vine genotype had the highest yields at 1.8 x 1.8 m, while the short-vine cultivar performed best with half that amount of space per plant (1.8 x 0.9 m). Production of short-vine cultivars might be improved by using even narrower planting distances.
