Thermal units or degree day systems can both be used to quantify relationships between plants and air temperature. The Northern Fluminense region holds no tradition for irrigated papaya (Carica papaya L.) cropping and, because of the need for irrigation, it is important knowing its growth and development characteristics under these conditions. This study aimed to determine the relationship between growth rate of papaya plants and degree days, and its effect on crop productivity, under different irrigation levels. An experiment was set up with the cultivar "Improved Sunrise Soil 72/12", in a randomized blocks design, with seven irrigation water depths and three repetitions; crop growth and yield parameters were evaluated. There were significant correlations between water depths and degree days. Polynomial models of 2nd and 3rd order appropriately fitted the relationships degree day versus plant height, stem diameter, crown diameter and number of emitted leaves, for each water depth. Growth parameters related to degree days and to the applied treatments are indicative of yield potential. The total water depth that promoted the greatest fruit yield was 2,937 mm.

King oyster (Pleurotus eryngii) mushroom is a palatable mushroom with high commercial potential due to relative ease of its growing technology, less cost of production and better yield potential, making it popular throughout the world. Therefore, an experiment was set up to assess the efficacy of different agro-wastes [cotton waste (CW) and fenugreek straw (FS)] on the morphology, yield and nutritional components of two strains (Pleurotus eryngii P9 strain and Pleurotus eryngii P10 strain) of Pleurotus eryngii. Studied indicators regarding time for pinhead formation, fruiting body development, biological efficiency and yield of both strains were significantly affected by different formulations of substrates. Substrates with 100 % CW exhibited maximum number of pinheads, yield and biological efficiency for both strains of king oyster as compared to other substrates alone or in mixture. This experiment indicates the possibility of Pleurotus eryngii cultivation on cotton waste and fenugreek straw in controlled conditions for enhanced growth and yield.

The use of magnetizers for the treatment of irrigation water can be used in agriculture as an alternative to increase the growth and yield of several crops. The objective of this study was to evaluate the effect of different irrigation depths and magnetic treatment of water on eggplant crop cultivated in protected environment. The study was carried out in two experiments, in the first one, the design was completely randomized with four replications and two factors: water depths (50, 75 and 100% ETc) for two water qualities (water treated by magnetizers and water without treatment). In the second one, the design was completely randomized with five replicates and two factors: water depths (75 and 100% ETc) for two irrigation water treatment (water treated by magnetizers and water without treatment). In the second experiment was ignored the treatment of 50% of ETc in order to increase the number of repetitions to check if there are differences between water treated to water without treatment. There were no significant differences in eggplant yield and growth as function of the magnetic treatment of water. The water depth that provided the highest yield, number of fruits per plant and stem dry matter in the two experiments was 100% ETc regardless of water quality.

Background: Groundnut is one of the most important oilseed crops of Odisha and grown in both in kharif and rabi-summer seasons. Because of excessive vegetative growth in kharif season, the yield potential is lower than rabi-summer resulting in low yield. Keeping this in view, an experiment was set up to investigate the effect of different concentration and time of paclobutrazol application on growth and yield of groundnut.Methods: A field experiment was conducted during kharif 2016 to 2018 at AICRP on Groundnut Research Farm, OUAT, Bhubaneswar, Odisha. The experiment was laid out in split plot design with different concentration of paclobutrazol in main plot and time of application in sub plot and replicated thrice. Recommended dose of 20:40:40 kg of N, P2O5 and K2O entirely applied as basal. Yield and yield attributing characters were taken at the time of harvest.Conclusion: Application of paclobutrazol at different concentration significantly reduced groundnut plant height and significant reduction was observed with application at 30 DAE. Among various yield attributing characters; pod/plant and pod yield increased significantly (24.6% and 27.4%, respectively) with application of paclobutrazol @ 100 ppm with higher benefit cost ratio of 1.97 and upto (8.4% and 17.5%) with application at 30 DAE.

TRIBAS is a biopesticide formulation developed from bacterial consortia of B. subtilis isolates. The formulation can control maize diseases, particularly those caused by pathogenic fungi. This research was conducted to validate the effectiveness of TRIBAS to support growth and yield of several maize inbred grown for parental seed production of several high yielding hybrids. A local seed growers’ participatory evaluation was set up in three districts in South Sulawesi (Maros, Soppeng, and Bone) using 5 maize inbred, i.e., MR-15, N-79, NEI-9008, AMB-20, and MAL-03. Each was grown following standard seed growing procedures with an additional treatment, with and without TRIBAS application. The results showed that the application of TRIBAS through seed treatment and plant spraying was able to inhibit the incidence of three main fungal diseases in maize, i.e, P. philippinensis, R. solani and B. maydis. The application did not result in significant seed productivity increase; however, it provides economic added value of up to IDR 5,724,000/Ha, considering that the seeds being propagated are parental seeds whose prices are relatively high (Rp 90,000/Kg). Continuous application of TRIBAS is expected to increase bacteria population in the soil, which, gradually would result in the increase of crop productivity.

Wheat (Triticum aestivum L.) is an important cereal crop of the world. It is one of the staple foods for major portion of world population. There are various biotic and abiotic factors responsible for low production of wheat in our country. Among these factors, soil salinity is major problem playing an important role in soil degradation, thus consequently reducing wheat production and quality. This study was conducted to evaluate the effect of various salinity and heavy metal levels against three wheat cultivars fir salinity resistance. Three different varieties of wheat were screened against the salinity under controlled conditions in the laboratory of tissue culture, University of Lahore. Seeds of three wheat varieties (Anaj-2006, Faisalabad-2008 and Inqalab-91) were sown in seedling trays. NaCl and CuSO4 were applied as salinity and heavy metal treatment upon wheat cultivars. In order to evaluate, hazardous effects of salinity and heavy metal on wheat certain growth parameters were observed i.e. leaf length and width, leaf area, stem and root length, fresh and dry weight of leaf, stem and root, root shoot length ratio and photometry of leaf, stem and root was measured. Results depicts salinity and heavy metal application has negative correlation with growth parameters of wheat particularly combine application of NaCl and CuSo4 have led to impose major detrimental effects on wheat cultivars. Regarding varietal comparison, “Anaj-2006” proved to be comparatively better in context of less salt’s residual accumulation in leaf, stem and roots along with lower root to shoot length ratio thus exhibiting a strong genetic potential to keep surviving and maintain healthy growth. However, it was concluded that salinity and heavy metal have adversely affected growth and yield potential of “Faisalabad-2008”. So conclusively, there is dare need to screen out indigenous and exotic wheat germplasm available throughout the country for finding some suitable genetic resources having moderate to high resistance levels against salinity and heavy metal which can be further used for breeding purpose in varietal improvement program.

In field trials for six years, the influence of weather parameters on pigeon pea was studied in the Alfisols of Bengaluru, Karnataka. Pooled analysis revealed that for delay in sowing by each day, the normal sowing month from June resulted in decreased yield of pigeon pea by 11.13 kg ha-1, thus indicating the importance of early and timely sowing to get the advantage of higher rainfall, rainy days (RD), length of growing period (LGP in days), growing degree days (GDD) and leaf area duration (LAD in days). Among the above RD, LGP, GDD, LAD were found to have influenced the yield of pigeon pea in Alfisols significantly. For achieving maximum yield, the optimum values of the above parameters obtained from the fitted quadratic curves, were 90 RD, 2600 GDD and 300 LAD during the cropping period. Among the 10 multiple linear regression (MLR) models established, model V was found to be the most reliable in judging the yield potential of pigeon pea.

A field study was conducted to investigate effect of phosphorus and different levels of irrigation on growth and yield of maize at the Agronomic Research Area, Faculty of Agricultural sciences and Technology, Bahauddin Zakariya University, Multan, during autumn 2016.The Experiment was laid out in randomized complete block design (RCBD) with split plot courses of action having three replications with net plot size of 4m x 3m. The crop was sown in 75 cm spaced rows, while plant to plant distance was maintained at 30 cm with the help of dibbler. Experimental treatments comprised of two irrigation level sand four phosphorus levels. The crop was harvested at maturity and the data were recorded by using the standard procedures. Maximum grain yield was obtained at full irrigation levels where phosphorus was applied @ 100 kg ha-1. All the growth and yield parameter increased with full irrigation levels with application of Phosphorus at the rate of 100 kg ha-1 while it was decreased where half irrigation was applied. Increase in P2O5 rates upto100 kg ha-1 enhanced the plant height, cob length, cob weight, thousands grain weight, Beyond application of 100 kg P2O5 ha-1 there was no significant increase in number of grains cob-1, thousand grain weight and other growth parameters. It is recommended that maize crop should preferably be fertilized @ 100 kg Phosphorus per hectare to get maximum grain yield under the ecological conditions of Multan.

Okra or Lady’s finger, botanically known as Abelmoschus esculentus (L.) Moench, is a tropical and sub-tropical indigenous vegetable crop commonly grown for its fibrous, slimy, and nutritious fruits and consumed by all classes of population. It has also several medicinal and economic values. Despite its many uses and potential value, its importance is under estimated, under-utilized, and considered a minor crop and little attention was paid to its improvement. The study was conducted to evaluate the effects of different planting densities and mulching materials on the growth and yield of okra grown in slightly sloping area in the marginal uplands in Sta. Rita, Samar, Philippines. A split-plot experiment was set up with planting density as main plot and the different mulching materials as the sub-plot which were: unmulched or bare soil, rice straw, rice hull, hagonoy and plastic mulch. Planting density did not significantly affect the growth and yield of okra. Regardless ofthe mulching materials used, mulched plants were taller and yielded higher compared to unmulched plants. Moreover, the use of plastic mulch resulted to the highest total fruit yield. The results indicate the potential of mulching in increasing yield and thus profitability of okra production under marginal upland conditions.

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.
