Ten genotypes of eggplant (Solanum melongena L.) comprising of four genitors and six hybrids generated using diallel crosses were evaluated to estimate the magnitude of genetic variability,  their general combing ability (GCA) and specific combining ability (SCA) for improved growth and yield of eggplant. The results obtained showed a significant (p ≤ 0.05) difference among the genotypes in all the traits studied.  The highest fruit yield per plant and fruit yield per hectare was obtained in ‘Yalo’ × ‘K3’ combination, with 1.77 kg per plant and 50.50 tonnes per hectare, respectively. The cluster analysis grouped the studied genotypes into three and six clusters for genitors alone and genitors with first filial generation (F1s), respectively. Principal component analysis showed that number of leaves, number of fruits and number of branches per plant contributed more to the total variations observed in the eggplant populations. Significant GCA and SCA effect were obtained for most characters analyzed, indicating the importance of both additive and non-additive genetic components. The genotype ‘Iyoyo’ was the best general combiner in regard to days to flowering and number of fruits per plant. ‘Yalo’ was the best general combiner in fruits’ circumference and diameter, fruit yield per plant and per hectare. The cross ‘Uyo’ × ‘Iyoyo’ was the best specific combiner in days to flowering, whereas ‘K3’ × ‘Iyoyo’ and ‘Yalo’ × ‘K3’ were the best specific combinations in number of fruits, fruit yield per plant and per hectare.

An experiment was conducted to determine the combined effect of biofertilizers and biocontrol agents on growth and yield of brinjal (Solanum melongena L.) under low cost polyhouse during off season in the experimental polyhouse of the College of Agricultural Engineering and Post Harvest Technology (CAEPHT), Central Agricultural University (CAU), Ranipool, Sikkim, India. The experiment was planned with 3 treatments and six replications viz. T1- Farm Yard Manure 5 kg/m2, T2- FYM 5 kg/m2 + biofertilizer (a mixture of Azotobactor + PSB at the rate 10 g/kg FYM each), T3- FYM 5 kg/m2 + biofertilizer + biocontrol agent (a mixture of Pseudomonas fluorescens + Trichoderma at the rate 5 g/kg FYM each). There was a significant variation in vegetative growth and yield among all the treatments. The maximum plant height (45.62 cm), the number of branches/ plant (11.17) and the number of leaves/ plant (50.05),the number of fruits/ plant (38.9) and fruit yield/ plant (810 g) were observed with treatment T3 which was at par with the treatment T2 and were significantly higher than the treatment T1 receiving FYM singly. Organic manure (FYM) inoculated with biofertilizers may therefore, be recommended for organic brinjal production for cultivation under low cost polyhouses in Sikkim (India) and application of biocontrol agents may be limited to areas having some history of occurrence of diseases because it involves an extra production cost in the application of biocontrol agents.

Nitrogenous fertilizer could improve the growth, yield and yield contributing characters of eggplant. The present investigation was aimed to find out the effects of different doses of nitrogen fertilizer on growth and yield of eggplant (Solanum melongena L.) which was conducted at Noakhali Science and Technology University during November, 2018 to March, 2019. The experiment comprises on eggplant local variety named ‘Tal begun’. There were four treatments of urea viz., 0, 12, 21 and 30 g urea pot-1 and the experiment were laid out in completely randomized design (CRD) with three replications. Different parameters were undertaken for the study like plant height (cm), number of leaves per plant, number of branches per plant, number of flowers per plant, number of fruits per plant, individual fruit weight (g). The variety showed significant variation for different doses. Among all treatments, 30 g urea pot-1 showed highest vegetative characteristics such as plant height (49.67 cm), number of leaves per plant (32.67), number of branches per plant (7.33) at 60 DAT and lowest vegetative characteristics was found from 0 g urea pot-1. On the other hand, the application of 21 g urea pot-1 showed medium vegetative characteristics and highest reproductive characteristics such as number of flowers per plant (6.67), number of fruits per plant (6.67), individual fruit weight (138.67 g). Therefore, the results showed that, nitrogen fertilizer strongly influenced vegetative and reproductive characteristics of eggplant. The findings of this study suggested that 21 g urea pot-1 performed the best and it will be suitable for eggplant production.

The study was carried out to find out the effect of zinc (Zn) and boron (B) on growth and yield of okra (BARI Dherosh 1). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The treatments of the experiment were, T0 (without Zn or B), T1 (20 kg Zn ha-1), T2 (30 kg Zn ha-1), T3 (10 kg B ha-1), T4 (20 kg B ha-1), T5 (20 kg Zn ha-1 + 10 kg B ha-1), T6 (20 kg Zn ha-1 + 20 kg B ha-1), T7 (30 kg Zn ha-1 + 10 kg B ha-1) and T8 (30 kg Zn ha-1 + 20 kg B ha-1) were undertaken to evaluate the best results of the study. The highest plant height was found in T8 (30 kg Zn ha-1 + 20 kg B ha-1) but the highest number of leaves plant-1 was recorded from T7 (30 kg Zn ha-1 + 10 kg B ha-1). On the other hand, the maximum leaf area index, SPAD value, mean fruit weight, fruit length, fruit diameter, fruit dry matter (%), number of fruits plant-1, fresh fruit weight plant-1 , fruit yield plot-1 and fruit yield ha-1 were found in T7 (30 kg Zn ha-1 + 10 kg B ha-1), while the control (T0) showed lowest performance for the respected parameters. It is strongly concluded that 30 kg Zn ha-1 with 10 kg B ha-1 combination may be helpful for okra cultivation in the field level to increase okra production.

To evaluate the effects of integrated nutrient management on growth and yield of BARI tomato-14 and soil fertility, a pot experiment was conducted in the net house of the department of Agricultural Chemistry of Bangladesh Agricultural University, Mymensingh during the period from October 2011 to April 2012. The experiment was laid out in a completely randomized design with 11 treatments and 3 replications. Treatments were control, RDCF100, 75% RDCF, 50% RDCF, 75% RDCF + PM2 t /ha, 75% RDCF + RS3 t /ha, 75% RDCF + PHRD, 50% RDCF + PM3 t /ha, 50% RDCF + RS5 t /ha, 50% RDCF + PHRD, PM3 t /ha + RS5 t /ha + PHRD. Among the treatments applied in combination of PM2 t /ha+ 75% of RDCF excelled in growth trends of morphological characters like plant height, number of branches plant- 1, number of leaves plant-1; available soil P and S. But sole application of RDCF100 recorded higher values for almost all morphological characters namely number of branches plant-1, number of leaves plant-1, fruit diameter, fruit weight plant-1 and yield of tomato following the same trend as seen in combined application of CF and PM. Among the plant hormone applied in combination, RDCF75% + PHRD showed the highest plant height. The more number of leaves plant-1, number of branches plant-1, yield and yield parameters as compared to other treatments were also significantly influenced by application of PH. Combined application of 50% of RDCF+RS5 t /ha increased exchangeable soil K. PM3 t /ha+ RS5 t /ha+ PHRD conserved more organic carbon and total soil N. Results showed that the integrated use of PM, RS along with CF increased the availability of nutrients throughout the growth period by maintaining the long term productivity for sustainable production of tomato.

This research aims to examine the effect of potassium chloride (KCl) fertilizer doses and defoliation percentage on the growth and the production of Fig (Ficus carica L.) and the interaction between these factors on the growth and production of fig plants. This research was conducted at the Screen House of Faculty of Agriculture, Syiah Kuala University, Darussalam, Banda Aceh. The research was carried out from July to September 2019. The research used split-plot design of 3 x 2 factorial RCBD with 3 replications. KCl fertilizer doses consisting of 3 levels (0 g tree-1 yr-1,700 g tree-1yr-1, 800 g tree-1 yr-1) and defoliation percentage consisting of 2 levels (30 % and 60 %). The result shows that KCl fertilizer dose has a very significant effect on increasing the number of leaves to 2, 4, 6, 8 and 10 WAT (week after treatment), increasing leaf length at 2 and 10 WAT, leaf width at 2 and 10 WAT, the number of branches at 2 and 10 MSP, branch diameter at 2 and 10 WAT, the number of fruits at 2, 4, 6, 8 and 10 WAT, and fruit weight at 2, 4, 6, 8 and 10 WAT. The best growth and yield of fig plants were found at a dose of KCl 800 g tree-1 yr-1with 15,4 t. ha-1 increasing fot two mounths harvest time. Percentage of defoliation has a very significant effect on increasing the number of leaves at 2, 4, 6, 8 and 10 WAT, the number of branches at 2 and 10 MSP, the number of fruits at 6 WAT, significantly affected in increasing the number of leaves at 2 and 10 WAT, leaf width at 2 WAT, the number of branches at 2 MSP, branch diameter at 2 and 10 WAT, the number of fruits at 4, 8 and 10 WAT. The best growth and yield of fig plants were found at 60% defoliation treatment1with 12,6 t. ha-1 increasing fot two mounths harvest time. Thus, there was a very significant interaction between the dose of KCl fertilizer and the percentage of defoliation on the increasing the number of leaves at 4, 6 and 8 WAT), leaf length at 2 and 10 WAT, leaf width at 2 WAT, the number of branches at 2 and 10 MSP, branch diameter at 2 and 10 WAT, the number of fruits at 2 WAT and significant interaction on the number of leaves to 2 WAT. The best growth and  yield of fig plants were found in a combination of a dose of 800 g tree-1 yr-1 of KCl fertilizer with 60% of defoliation.

Present study aimed to evaluate the production potential of cape gooseberry (Physalis peruviana L.) in sodic soil (pH 8.56) under varying plant spacing and soil fertility levels. The spacing treatments were S1-75 x 60 cm, S2-75 x 75 cm and S3-90 x 75 cm, while native soil fertility was manipulated through the application of NPK fertilizers i.e. F0-control (no NPK fertilizers), F1 - 60:40:40, F2 - 80:60:60, and F3 - 100:80:80 kg NPK ha-1. Two year’s data from the study revealed that spacing and NPK treatment had significant effect on vegetative growth and fruit yield during both the years. Closest spacing (75 x 60 cm) resulted tallest plants (103.41 and 100.35 cm) and maximum fruit yield (86.69 and 83.56 q ha-1), but this treatment was statistically at par with 75 x 75 cm spacing. Widest spacing (90 x 75cm) resulted maximum number of branches (34.14 and 32.49 plant-1), number of leaves (167.31 and 162.70 plant-1) and average fruit weight (9.26 and 9.18 g), but was statistically at par with 75 x 75 cm spacing. Amongst the fertilizer treatments, application of NPK @100:80:80 kg ha-1 resulted maximum plant height (114.88 and 11.65 cm), number of branches (35.78 and 34.82 plant-1), number of leaves (174.82 and 172.55 plant-1), fruit weight (9.62 and 9.57 g) and fruit yield (101.08 and 98.08 q ha-1). Biochemical quality of fruits (TSS, ascorbic acid, acidity, and reducing, non-reducing and total sugars) was increased due to increased fertility level and recorded maximum with the application of 100:80:80 kg NPK ha-1. These findings will be helpful in exploring cape gooseberry cultivation in sodic soils (pH 8.56) through suitable agronomic manipulations in plant spacing and soil fertility levels.

Field experiments was conducted during the 2015 rainy season at Teaching and Research Farm of Department of Crop Science, Taraba State College of Agriculture Jalingo, to investigate the effect of Nitrogen rates on the growth and yield of Bambara groundnut (Vigna subterranean (L.) Verdc) in Jalingo. The experiments was laid out in split-plot design with three replications and three nitrogen rates, 20kgNha-1, 25kgNha-1 and 30kgNha-1 as main plot treatment while four intra-row spacing, 20cm, 25cm, 30cm and 35cm as the sub plot treatment. The sub plot size was 3m x 2m (6m2). The nitrogen rate doses were applied a week after emergence of the seedlings. Data collected were, percentage seedlings emergence, number of leaves per plant, number of branches per plant, plant height, number of nodules per plant, number of effective nodules per plant, number of non-effective nodules per plant, days to 50% flowering, number of pods per plant, number of seeds per plant, 100 seeds weight, grain yield per plot and grain yield per ha-1. Data collected were subjected to Analysis of Variance (ANOVA), means were separated using Least Significant Difference (LSD). The results showed that nitrogen rate applied had no significant influence on growth and yield characters. However, significant influence was recorded of intra-row spacing on number of leaves per plant and number of branches per plant at 6WAS with a mean value of 48.24 and 16.80 respectively. Intra-row spacing, 25cm gave the highest mean number (3.14) of non-effective nodules per plant at 30 DAS while 25cm gave the highest number of days to 50% flowering. The result of the interaction revealed that there were significant interaction between Nitrogen rates and intra-row spacing on the number of leaves at 3 WAS and 6WAS. It is recommended that nitrogen rate of 20kgNha-1 and intra-row spacing of 35cm be adopted for Bambara groundnut in Jalingo.
