Leaf Yield

An experiment to ascertain the influence of fruit size on the yield of fluted pumpkin (Telfairia occidentalis Hook F.) was conducted in 2011 and 2012 at Nsukka. The mature fruits of T. occidentalis were graded into three length groups: large (more than 50 cm), medium (34-50 cm) and small (less than 34 cm). The experiment was laid out in randomized complete block design with six replications. The following data were collected: length of the longest vine, number of leaves/plant, vine diameter, marketable leaf and fruit yield. Data collected were subjected to analysis of variance while Genotype by Genotype x Environment interaction biplot was used to show which-won-where among the groups. Significant means were separated using Fisher’s least significant differences. Medium sized fruits gave the highest marketable leaf yield that was significantly higher than the small sized fruits in both years. Small sized fruits were significantly (p<0.05) lower in total leaf yield, fruit weight/hectare, fruit circumference (33.9 cm) and length (22 cm). The biplot explained 100% of the variation in the fruit sizes. Large sized fruits were the best performer in fruit length, while medium sized fruits performed better in total marketable leaf yield, average fruit weight, number of fruits/hectare and total fruit weight/hectare. The highest Benefit Cost Ratio of 1.2 and 2.6 in 2011 and 2012, respectively were obtained from medium sized fruits Medium sized fruit are recommended in favour of small sized fruit for leaf and fruit production, having higher economic returns.

Abstract Cucumber (Cucumis sativus L.) is an important vegetable crop, rich in vitamins and minerals and eaten fresh as a dessert. Its fruit yield is relatively low, though could be improved through knowledge of character association with it and selection of desirable materials for improvement programmes. Fifteen cultivars of Cucumber were evaluated at two locations (Abeokuta and Ibadan), South West, Nigeria in a randomized complete block design with three replicates in order to determine heritability, correlation, direct and indirect effects of characters on fruit yield. Data collected on agro-morphological characters were subjected to analysis of variance, estimates of heritability, correlation, and path analysis. Significant variations (p <0.05) were observed in the cultivars. High heritability estimates (>90%) was observed for fruit length at both locations. A significant phenotypic and genotypic correlation was observed between fruit yield and fruit weight. Number of days to 50% flowering and fruit width could also be selected directly for improvement of fruit yield in cucumber.

 Thirteen selected chilli genotypes were evaluated in randomized completely block design with three replications to study the flowering, fruit set and yield potential during spring-summer of 2005 at Khajura, Banke (Western terai district of Nepal). High temperature, long drought period and hot wind blow during flowering and fruiting period severely affected the fruit set and fruit size. Only 18.81% flowers set fruits while 72.41% of set fruits reached to marketable size (harvesting). Wide variations observed in yield potential of the genotypes ranging total fruit number per plant from 6 to 71 and in total fruit yield 7.97 to 95.33 q/ha. The genotype Mr. Lee No. 3 Selex produced maximum marketable fresh fruit yield (90.69 q/ha) which was 234.5% higher than that of Jwala (standard check) with 50.57% fruit set and 74.93% fruit retention. One fruit per plant was 0.63 and 0.52 coefficient of fruit set (%) and fruit retention (%) respectively. Highly significant coefficient of determination (R2=0.86) of the product of fruit number per plant and 100 fruit weight (g) against fresh fruit yield (q/ha) showed that chilli genotypes yield can be predicted considering fruit number per plant and fruit weight in hot and dry summer condition.Journal of the Institute of Agriculture and Animal Science.Vol. 33-34, 2015, page: 229-236

Information on some agronomic practices are required for muskmelon production as there is no record of its production in Ado-Ekiti. A field study of 3 x 2 factorial experiment of sowing dates (January, May and September) and NPK 15:15:15 fertilizer application (0 and 333 kg ha-1) was laid out in a Randomized Complete Block Design in three replicates at the Teaching and Research Farm of Ekiti State University, Ado-Ekiti, Nigeria. Data collected on the number of leaves and branches, leaf area, vine length, day to flowering, 50% flowering, number of fruit, fruit size and yield were subjected to analysis of variance and treatment means separated by Duncan's Multiple Range Test at 5% probability. Dates of sowing did not significantly influence growth but muskmelon planted in May gave a higher number of leaves plant-1, leaf area and vine length. Fertilized plants produced better growth and earlier flowering than unfertilized plants. The number of fruits ha-1, average fruit weight and fruit yield ha-1 of 11606, 0.78 kg and 9.09 t ha-1 respectively were produced by fertilized plants which were significantly higher than 10036.70, 0.28 kg and 2.44 t ha-1 from unfertilized plants. Muskmelon planted in September produced a higher number of fruits and fruit yield of 12418 and 11.29 t ha-1 while muskmelon planted in May produced higher fruit weight (0.94 kg) but these did not differ significantly from other sowing dates. Planting muskmelon under the rain-fed condition with adequate fertilizer application gave better performance and is thereby recommended for muskmelon production in Ado-Ekiti.

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.

Genotype x environment interaction (GxE) information is needed by plant breeders to assist the identification of superior genotype. Stability analysis can be done if there is a GxE interaction, to show the stability of a genotype when planted in different environments. This study aimed to estimate the effects of genotype x environment interaction on yield and yield components of fruit weight per plant as well as to look at the stability of 14 tomato genotypes at four lowland locations. The study was conducted at four locations, namely Purwakarta, Lombok, Tajur and Leuwikopo. Experiments at each location was arranged in a randomized complete block design with three replications. Stability analysis was performed using the AMMI model. Fruit weight, fruit diameter, number of fruits per plant and total fruit weight per plant characters showed highly significant genotype x environment interactions. Variability due to the effect of GxE interaction based on a AMMI2 contributed by 88.50%. IPBT3, IPBT33, IPBT34, IPBT60 and Intan were stable genotypes under AMMI model.<br />Keywords: AMMI, multilocation trials

A multi-environment yield trial is important to understand the genotype by environment interaction and to select high performing and stable crop varieties. The aim of this study was to identify high yielding and stable hybrid maize varieties for mid altitudes of Rwanda, to compare the performance of new hybrid varieties with commercial checks, and to determine the extent of genotype by environment interaction. Maize is a staple crop used to fight hunger and malnutrition in developing countries. Different varieties have been released to increase yield including Open Pollinated Varieties (OPVs) and hybrids. Genotype by Environment interaction is an issue that all breeding program need to overcome. In the future, improved varieties will be needed in order to increase income for farmers and help in food security Field experiments were conducted to assess the performance and the stability of 27 maize varieties in the mid altitudes zone of Rwanda in the Cyabayaga, Rubona and Bugarama sites. The experimental design was alpha lattice (0,1) with a Randomized Complete Block Design (RCBD). Data were collected for a number of characters i.e. silking, Antesis-Silking Interval (ASI), plant height, plant aspect, ear per plant, husk cover, ear aspect, ear rot and grain yield. Data were analyzed by GenS Stat statistical computer package, Discovery Edition. ANOVA and AMMI analysis were applied to assess the performance and the stability of varieties and the degree of genotype by environment interaction (G×E). In addition, Principal Component Analysis (PCA) and cluster analysis were conducted to assess relationships between varieties. The results showed that RHM1706, RHMM1701, RHM1409, RHMM1707, WH509, RHMM1704, RHM407, WH101, RHMM1710, RHMM1708, PAN53 and RHM104 were stable across locations. Furthermore, the evaluated varieties were found to cluster into five groups. Varieties found to be most stable are recommended for further use.

AbstractA long-term study was conducted to explore the possibility of using traditional rain-fed systems for growing domesticatedZiziphus mauritiana(so-called Pomme du Sahel) in the Sahel. Five varieties, Gola, Ben Gurion, Seb, Umran and Kaithli, were grafted on six rootstocks ofZ.mauritianafrom various agroecological zones of Niger. Trees were planted inside microcatchments at 8 × 8 m spacing. Over a period of six years, the variety Umran gave the highest fruit yield (3600 kg·ha−1) and the lowest fruit yield was documented for variety Seb (1970 kg·ha−1). Individual fruit weight ranged from 25.8 g for ‘Umran’ to 9.5 g for ‘Seb’. The rootstocks had no effect on average fruits yields and fruit size. There was a significant linear correlation between fruit yield and annual rainfall. In a rainy year (680 mm), the average yield of the five varieties was 7580 kg·ha−1. The results of the current study indicate that dry land plantations of Pomme du Sahel can guarantee food security during dry years in the Sahel. However, further studies are required to evaluate the economic feasibility of this system.

A field Investigation was carried out to study the effect of fertigation on yield, fertilizer use efficiency and economics of hybrid ridge gourd [Luffa acutangula (L.) Roxb] Arka Vikram during 2018-2019 at Vegetable Research Block of ICAR- Indian Institute of Horticultural Research, Bengaluru, Karnataka. The experiment was laid out in randomized complete block design having eight treatments and three replications. The results of the experiment revealed   that   the  treatment  T3    i.e  application of water soluble  fertilizers @ 150:90:150  kg  NPK  ha-1 through fertigation recorded maximum number of female flower per vine (29.73), number of fruits per vine (19.68), fruit length (49.76 cm), fruit girth (18.40 cm), average fruit weight (454.03 g), fruit yield per vine (4.03 kg) and fruit yield per hectare (53.73 t). Application of water soluble fertilizers @ 150:90:150 kg NPK ha-1 through fertigation (T3) recorded significantly higher fruit yield per hectare (53.73 t ha-1), which was higher to the tune of 23.8 to 70.4 per cent than other treatments tested in hybrid ridge gourd. The second highest fruit yield was obtained with T2 (43.40 t ha-1) followed by T1 (42.10 t ha-1). However, T5 i.e application of water soluble fertilizers @ 50:30:50 kg NPK ha-1 resulted in highest fertilizer use efficiency (245.38 kg yield kg-NPK-1) compared to other treatments. Fertigation at 100% NPK dose along with mulching with silver-black plastic mulch gave the highest net income (Rs.555435.0 ha-1) and B: C ratio of 2.22.
