Anand Agricultural University, Anand
Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur
AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

CVS 'KESAR' AND 'AMRAPALI(AAU, Anand, 1989) SINGH, DHIRENDRA BAHADUR; Chundawat, B. S.Present investigation on the effect of post harvest treatments on ripening changes and quality of mango fruits (Mangifera indicaL.) CVS 'Kesar' and 'Amrapali' was conducted at the research laboratory of the Department of Horticulture, B.A.College of Agriculture, Gujarat Agricultural University , Anand Campus, Anand in the year 1987-88 and.1988-89. This study revealed that ripening of fruits at controlled temperature (22-25°C and RH 85-90 %) significantly increased the number of days required for ripening reduced the physiological loss in weight (PDf) and fruit damage. This was followed by GA 150 ppm + Bavistin 1000 ppm treatment. Quality of ripe fruits in terms of high TSS, Yitamin-C and total Sugars and low level of acidity was also highest in controlled temperature treatment. In pre-ripening treatment of mango fruits with GA 150 ppm + Bavistin 1000 ppm, the overall quality of ripe fruit barring Vit-C which was higher than control, was at par with control fruits. This indicates that this treatment has tendency towards higher quality or with no adverse effect on quality what so ever. These treatments slowed down the process of ripening by retarding the activities of Peroxidase, Catalase and PME enzymes . and reduced the rate of respiration and ethylene production initially and postponed the climacteric peak.ThesisItem Open Access INFLUENCE OF DECAPITATION, PARTIAL ROOT PRUNING AND EXOGENOUS APPLICATION OF PLANT GROWTH REGULATORS ON THE GROWTH, YIELD AND QUALITY OF POTATO(AAU, Anand, 1980) PATEL, BABUBHAI MAGANBHAI; Majmudar, A. M.The response of potato var Up-to-date in respect of its growth, yield and quality was studied by altering the natural hormonal balance through pruning treatments as well as hormonal sprays. The three pruning treatments were - (A) normal plants (intact I.e. without any pruning treatment), (B) decapitated plants (pinching off of the apex of each sprout) and (C) partly root pruned plants (cutting the roots from all the four sides of the sprout at a distance of 10 cm from the main stem). The level of KIN used were 0, 15, 30 and 60 ppm; those of IAA were 50, 100 and 200 ppm and those of GA were 50, 100 and 150 ppm. Pruning treatments were given at 7-9 leaf stage, while single spray of IAA and GA was given at 10-12 leaf stage and that, a single foliar spray of KIN was superimposed (over IAA and GA) at 15-17 leaf stage.ThesisItem Open Access INFLUENCE OF DECAPITATION AND PGR's ON GROWTH, YIELD AND QUALITY OF CLUSTER BEAN SEED (Cyamopsis tetragonoloba L. Taub.) CV. PUSA NAVBAHAR(AAU, Anand, 2010) NARSHI, SATODIYA BAKUL; Patel, H. C.A field experiment was conducted at Main Vegetable Research Station, Anand Agricultural University, Anand during the years 2008-09 and 2009-10 in summer seasons on sandy loam soil with a view to study the "Influence of decapitation and PGR's on growth, yield and quality of cluster bean seed (Cyamopsis tetragonoloba L. Taub.) cv. Pusa Navbahar" under middle Gujarat conditions. There were twenty one treatment combinations comprising three decapitation treatments i.e. D1-Without decapitation (control), D2-Decapitation at 70 DAS and Ds-Decapitation at 85 DAS and seven different PGR's treatments along with control i.e. G1 -Water spray (Control), G2-NAA 20 mg/l, G3-NAA 40 mg/l, G4-GA3 20 mg/l, G5-GA3 40 mg/l, G6-Thiourea 500 mg/l and G7-Thiourea 1000 mg/l in a Randomized Block Design (Factorial) with three replications. Growth parameters viz. plant height and number of leaves per plant were found non-significant at 30 and 60 DAS. Whereas, without decapitation (control) treatment recorded significantly the highest plant height i.e. 112.07 and 115.72 cm and number of leaves per plant i.e. 50.70 and 45.15 at 90 DAS and harvest stage, respectively. The effects of decapitation on physiological parameters viz. LA, LAI, CGR, NAR and dry weight of plant were found non-significant at 30 and 60 DAS whereas, at 90 DAS all the physiological parameters and at harvest only LA and dry weight of plant recorded significantly, higher values in control treatment (Without decapitation). Decapitation of plant at 70 DAS registered significantly the highest number of pods per cluster (7.55), number of clusters per plant (18.29), number of pods per plant (138.00) and weight of 1000 seeds (37.00 g) in pooled analysis. However, dry pod length (9.59 cm) and number of seeds per pod (7.05 cm) were found maximum in treatment decapitation at 85 DAS. Decapitation of plant at 70 DAS produced significantly the highest seed yield (917.7 kg/ha) in pooled analysis as compared to without decapitation (889.13 kg/ha), which was 9.26 % higher than without decapitation. Root and shoot ratio (0.057) and harvest index (627.04) were also found significantly superior in treatment decapitation at 70 DAS. Seed quality parameters viz. seedling length, seedling dry weight, vigour index-I and II were recorded the highest values in treatment decapitation at 70 DAS at 6th 8th and at 10th day on pooled basis. Plant growth regulators treatments significantly influenced growth parameters viz. plant height and number of leaves per plant at various growth stages of crop except at 30 DAS. At 60, 90 DAS and harvest stage treatment GA3 40 mg/l recorded significantly maximum plant height and number of leaves per plant as compared to rest of treatments. Physiological parameters viz. LA, LAI, NAR and dry weight of plant at 60 and 90 DAS registered significantly the higher values in treatment GA3 40 mg/l in pooled analysis. At harvest, LA, LAI and dry weight had recorded significantly maximum values in treatments Thiourea 500 mg/l and GA3 40 mg/l which remained at par with each other. Yield attributing characters viz. number of pods per cluster (7.25), number of clusters per plant (18.75), number of pods per plant (136.01), dry pod length (9.86 cm) and weight of 1000 seeds (37.22 g) were significantly the highest in treatment Thiourea 500 mg/l on pooled basis. The significantly maximum seed yield was recorded by the treatment Thiourea 500 mg/l (1030.36 kg/ha) in pooled analysis, which was at par with treatment GA3 20 mg/l (992.81 kg/ha) which was 26.67 and 22.05 %, higher than control, respectively. The treatment GA3 20 mg/l recorded the highest harvest index (638.80). Seed quality parameters viz. germination percentage, seedling length, seedling dry weight and vigour index-I and II were recorded the maximum values in treatments of GA3 and Thiourea at all the three stages i.e. 6th, 8th and 10thday. Interaction effects between decapitation and PGR's treatments on growth parameters viz., plant height and number of leaves per plant showed significant differences at 60, 90 DAS and harvest stage except for number of leaves per plant at harvest. Different combination of decapitation and PGR's treatments recorded significant results on physiological parameters at various growth stages viz. LA, LAI, CGR, NAR and dry weight of plant. At 60 and 90 DAS LA, LAI, NAR and dry weight of plant recorded significant results in different combinations except CGR at 60 DAS. At harvest stage, CGR, NAR and dry weight of plant were found significant due to interaction between decapitation and PGR's treatments. At all the growth stages, interaction between without decapitation and treatments of GA3 and Thiourea recorded significantly higher values of all the physiological parameters. Yield attributing parameters viz. number of seeds per pod and weight of 1000 seeds significantly affected by interaction between decapitation and PGR's treatments which, were the highest in combinations D'aGe (8.20) and D2G6 (41.40 g), respectively. Seed quality parameters like, seedling length, seedling dry weight and vigour index-I and II recorded the maximum values in combinations of decapitation at 70 DAS with treatments of GA3 and Thiourea at all the three stagesi.e. 6th 8th and10th day. The higher net return of 47,849 Rs./ha along with B.C.R. of 1: 2.60 was obtained by decapitation at 70 DAS, whereas, the lowest net realization (41,935 Rs. /ha) and B.C.R. (1:2.43) was obtained when plant decapited at 85 DAS. The treatment Thiourea 500 mg/l recorded the maximum net realization of Rs. 52,277 per hectare with 1:2.73 B.C.R., followed by treatment GA3 20 mg/l.ThesisItem Open Access LINE X TESTER ANALYSIS FOR COMBINING ABILITY, HETEROSIS AND GENE ACTION IN OKRA (Abelmoschus esculentus (L.) Moench(AAU, Anand, 2004) AHLAWAT, TIMUR RAMPAL; Joshi, K. I.The present investigation entitled "Line x Tester analysis for combining ability, heterosis and gene action in okra (Ahelmoschus esculentus (L.) Moench)" was undertaken at Main Vegetable Research Station, Gujarat Agricultural University, Anand during kharif 2000 and 2001. The experimental material comprising of fifteen females, five males, their 75 hybrids and standard hybrid check GOH-1 was evaluated in a randomized block design with three replications in both the environments. Observations were recorded on fruit yield per plant and eight other yield components. The individual environment-wise and pooled analysis of variance revealed sufficient variation among the genotypes for all the traits studied, indicating the existence of sufficient variability in the material. The pooled analysis over environments revealed that environmental differences were non-significant for all the characters, thereby suggesting that the characters were not influenced by the changes in environment. Considerable level of heterosis was observed for fruit yield and its component traits. Maximum heterosis was observed for number of primary branches per plant followed by fruit yield per plant, plant height, fruits per plant and fruit weight. However, the magnitude of heterosis varied in different environments for the various traits studied.ThesisItem Open Access IMPACT OF POST-HARVEST TREATMENTS ON SHELF-LIFE AND QUALITY OF SAPOTA [Manilkara achras (Mill.) FOSBERG] FRUITS AND CHIPS CV. KALIPATTI(AAU, Anand, 2013) PATEL, PINAKIN DASHRATHBHAI; Vihol, N. J.With objective to evaluate the efficacy of different growth regulators with wax coating for quality parameters of sapota fruits and chips, to extend the shelf-life of sapota fruits and chips and to find out the best combination to minimize the post-harvest losses in sapota fruits at ambient condition an experiment was conducted at the laboratory of the Department of Horticulture, Anand Agricultural University, Anand during the year 2007-08 and 2008-09. In sapota fruits, fruit weight and fruit volume was considerable the higher under the treatment of AgNO3 @ 20 ppm. The physiological loss in weight was minimized under the treatment of AgNO3 @ 40 ppm during early i.e. 6th, 9th and 12th day of storage period. Generally marketability of the sapota fruits was quite high under the treatment of GA3 @ 100 and 200 ppm throughout the storage period during both the years of experiment. Due to prevailing high temperature during the storage period, fruits showed high tendency to shrivel. The treatment GA3 @ 200 ppm delayed rate of ripening during the both years. Fruits treated with this treatment required 9.33, 9.00 and 9.17 days for ripening during both years as well as in pooled results. Considerable compactness of sapota fruits was observed under the treatment of NAA @ 200 ppm during second year experiment and in pooled data. Most of the fruits showed high tendency to shrivel due to high temperature prevailed during the storage period of both the years. Quality of ripe fruits in terms of high T.S.S. (22.00, 21.75, 22.50, and 22.75 0brix) was recorded under the treatment of GA3 @ 100 ppm throughout the storage period on pooled basis during both the year experiment. Lower acidity (0.089 %) was recorded under treatment of NAA @ 200 ppm during early storage i.e. at 6th day of storage followed by GA3 @ 200 ppm treatment which recorded considerable the lowest acidity (0.065, 0.038 and 0.021 %) on pooled basis at 9th 12th and 15th day of storage in both year experiment. Reducing sugars content (8.55 %) was higher under AgNO3 @ 20 ppm during 9th day of storage period followed by GA3 @ 100 and GA3 @ 200 ppm treatment, which recorded 8.98 and 9.62 per cent acidity at 12th and 15th day of storage, respectively on pooled basis. The fruits treated under AgN03 @ 40 ppm found to accumulate higher total sugars (17.77, 18.10 and 18.41 %) during 6th, 9th and 12th day of storage, while, 20.13 per cent of total sugars was recorded under the treatment of NAA @ 200 ppm at 15th day of storage period. Organoleptic score was not influenced by the growth regulators and AgN03. Sapota fruits treated with wax 6 per cent showed considerable high fruit weight (82.97 g) and volume (64.39 ml) at final stage of storage and the minimum physiological loss in weight throughout the storage period resulted in delayed the rate of ripening by recording 7.78, 8.06 and 7.92 days to reach ripening. The treatment also found to control spoilage at 12th and 15th day of storage. Wax coating treatment could not much influence the quality characters viz., T.S.S. and acidity throughout the storage period. Higher reducing sugars (8.12, 8.27, 8.63 and 8.84 %) and total sugars (16.02, 17.20, 17.75 and 18.95 %) were recorded under the treatment of wax 3 per cent in pooled data during second year of experiment during all the days of storage period, respectively. Looking to the organoleptic score of sapota chips, higher score for colour (6.83 and 6.50) was recorded under the treatment of GA3 @10G ppm during second year. Under treatment NAA @ 200 ppm 30.67 per cent recovery of chips could achieved during second year. Reducing sugars content (26.21, 25.25, and 25.73 %) at 3rd month and (26.73, 26.00 and 26.37 %) at 6th month was noted under the treatment of NAA @ 100 ppm during first and second year as well as in pooled data, respectively. The treatment GA3 @ 200 ppm showed higher accumulation of total sugars (51.73, 50.15, 51.93 and 50.40 %) during both the years at 3rd and 6th month of storage period, respectively. Wax coating treatment could not influence much more on organoleptic evaluation, physical parameter and chemical parameters of sapota chips. From the above mentioned results it can be concluded that GA3 @ 200 ppm was the best treatment which not only extend the shelf-life of sapota fruits but also reduced the post-harvest losses and degradative metabolism during ripening without adversely affecting quality of sapota fruits cv. 'Kalipatti'. Dipping of fruits in different growth regulators incorporated with wax 6 per cent could help to reduce the post-harvest losses the fruits. For improving the quantitative and qualitative parameters of sapota chips GA3 @ 100 and GA3 @ 200 ppm was found to be the best treatment, respectively.ThesisItem Open Access EVALUATION OF VARIOUS GENOTYPES AND HYBRIDS OF AONLA (Emblica officinalis Gaertn.)(AAU, Anand, 2005) JADAV, RAMSANG GAMBHIRSANG; Khimani, R. A.The experiment entitled "Evaluation of various genotypes and hybrids of aonla (Emblica officinalis Gaertn.)" was conducted at the Horticultural Research cum Demonstration Farm, B. A. College of Agriculture, Anand Agricultural University, Anand during the year 2002-03 and 2003-04. The experiment was split in two sets i.e. set-1 Evaluation of genotypes of aonla and set-II evaluation of hybrids of aonla. In the first set, eight genotypes (LS-9, LS-10, LS-lOA, LS-U, LS-13, LS-16, LS-18 and LS-20) were used along with two checks (GA-1 and NA-7) and in the set-II thirteen hybrids (C1-1, C1-2, C1-3, C1-5, C1-6, C1-7, C1-13, C1-14, C2-1, C2-2, C2-3, C2-4 and C2-5) were used with the two checks (GA-1 and NA-7) to screen for various morphological, physico-chemical and post harvest traits of aonla. The experiments were planned in a Randomized Block Design during both the years of study (2002-03 and 2003-04). Set - I Selected genotypes Results pertaining to different selected genotypes of aonla, revealed that all the growth parameters like tree height, spread and trunk diameter of different genotypes showed marked variation and genotype LS-16 had maximum height (5.88 m), while the maximum trunk diameter (0.95 m) with maximum spread was observed in LS-11. The number of determinate branches produced on 30 cm length of tagged indeterminate branch were maximum in LS-16 (39.13) and in LS-18 (37.06). The length of determinate branches was higher LS-18 (15.33) and LS-20 (13.33). However, the maximum leaflets count (217.38) and area (38.26 cm2) was recorded in GA-1. The genotypes exhibited wide variation for count of male and female flowers. The maximum count of male flowers was noticed in LS-18 (987) while that of female flowers in GA-1 (55.10). The lowest male female ratio was observed in GA-1 (13.92). The genotypes LS-9, LS-20 and check NA-7 exhibited lower count of premature fruit drop at pea stage, while at marble stage it was seen in LS-16 (0.87) and NA-7 (0.88). The vertical diameter (3.19 cm) and fruit volume (28.04 cc) was maximum in GA-1 during the present study and, it produced significantly maximum fruit yield per quarter of tree during both the years of study followed by NA-7, LS-16 and LS-18. Lower stone weight was recorded in LS-16 (3.09 g) and higher pulp was observed in LS-9 (26.95 g) and GA-1 (26.14 g). The biochemical analysis showed significantly wide variation among the genotypes for different traits. The TSS was maximum in LS-9 (13.03 %) and ascorbic acid was higher in LS-10A (723.43 mg-100g pulp) and in GA-1. However LS-16 exhibited minimum acidity (1.72 %) and tannin (1.70 %) content. The maximum fibre percentage was found in LS-20 (3.58 %), while less fibre was noticed in GA-1 (2.69 %) and NA-7 (2.80 %). During the two years of study, LS-lOA (14.50 days), LS-16 (14.25 days), and check GA-1 (13.50 days) had longer marketable shelf life after harvest and a lower physiological weight loss after twelve (12.73 %) and twenty four days (28.73 %) was noticed in GA-1. Set - II Evaluation of hybrids The F1 hybrids of aonla illustrated significant variation for different morphological, physico-chemical and post harvest quality traits. The maximum tree height (9.42 m), trunk diameter (1.52 m) and spread (7.92 m E-W and 7.61 m N-S) were found in C1-1 in the present study. The number and length of determinate branches was higher in C1-5 (36.63 and 14.44 cm) on pooled basis. The check GA-1 produced maximum number of leaflets (217.38) and leaflet area (38.26 cm2) followed by C1-5. The maximum count of male flowers was recorded in C2-5 (944.63) and of female flowers in C1-5 (38.13), however the sex ratio was lower in GA-1 (22.24) on pooled basis. The Ci-13 and C2-2 showed minimum count of dropped fruits at pea stage and in C2-2 it was minimum at marble stage. The weight of dropped fruits was least in C1-13 at pea and marble stage. The present study showed significant variation in fresh weight of aonla fruits. It was maximum in C1-5 (31.79 g) followed by C2-2, and GA-1. The check GA-1 recorded maximum count of fruits (1164.13) and fruit yield (26.41 kg) per quarter of tree followed by C1-5, C1-1 and NA-7. The fruits of hybrids showed marked variation in diameter, volume, juice content, pulp content, stone weight and dry pulp recovery. The C1-5 illustrated maximum vertical (3.31 cm) and horizontal (3.46 cm) diameter. A lower stone weight (2.54g) was recorded in C2-2, maximum fresh pulp weight (28.50 g) in C1-5 and highest juice volume (24.47 cc) as well as dry pulp recovery was noticed in GA-1. The findings showed that hybrid C1-5 recorded maximum TSS (17.51 %) and check GA-1 had maximum ascorbic acid (715.41 mg-100g pulp) and protein (1.08 %) during the study. The fruits of hybrid C2-3 had lower acidity percentage (1.85 %) and C1-13 had lower tannin content (2.32 %). The lowest fibre was recorded in C1-3 (2.55 %). Different heterogeneous variable of aonla had wide variation in marketable shelf life and was higher in C1-5 and GA-1 during the study. The lower per cent physiological weight loss of fresh aonla fruits was noticed in C1-5, GA-1 and C2-3 after twelve days and in C2-5, C1-5 and in GA-1 after twenty four days of harvest.ThesisItem Open Access STUDIES ON LEAF NUTRIENT STATUS IN RELATION TO DIFFERENT PERIOD AND POSITION IN AONLA (Emblica officinalis Gaertn) CULTIVAR GUJARAT AONLA-1(AAU, Anand, 2002) PARMAR, MAYANKKUMAR A.; Kikani, K. P.The investigation on "Studies on leaf nutrient status in relation to different period and position in aonla (Emblica officinalis, Gaertn) Cultivar "Gujarat Aonla-1" was carried out at Horticultural Research Farm, B.A.College of Agriculture, Gujarat Agricultural University, Anand Campus, Anand during the year 2000-2001. Leaf was choosen as an index tissue and it was collected from five different position of shoot at bimonthly interval starting from June, 2000 to April, 2001 and leaf samples were analyzed for the nitrogen, phosphorus, potassium, calcium and magnesium content on dry weight basis. The experimental trees received uniform cultural practices but manures and fertilizers each at two levels before on set of monsoon. Vegetative growth and yield were also recorded for different 16 treatment combinations. Significantly highest leaf level of nitrogen content (3.09 per cent) was found in treatment combination N2P1K1F1 (i.e. 1500 g N + 750 g P + 750 g K + 100 kg FYM/tree) in the month of August when leaf samples were collected from the top portion of the indeterminate branch from middle position of tree and it was lowest (0.08 per cent) in treatment N1P0K0F0 (i.e. 1000 g N + 0 g P + 0 g K + 0 kg FYM/tree) in the month of February at the basal position. Treatment N2P1K1F1 recorded significantly higher leaf level of phosphorus content (1.32 per cent) in the month of August at basal position while, it was lowest in the treatment N1P0K1F0 (0.03 per cent) in the month of February at top position. Leaf level of potassium content was significantly highest (1.41 per cent) in treatment N2P1K1F1 in the month of June when leaf samples were collected from top portion of indeterminate branch from middle portion of the tree and it was lowest (0.10 per cent) in treatment combination N1P1KoFo in the month of August at basal position. An interaction between treatment, period and position for leaf level of calcium content was found to be significant and it was recorded maximum (1.54 per cent) in treatment combination N2P1K1F1 in the month of October at basal position and minimum (0.30 per cent) in N1P0K0F0 treatment in the month of June at top position. Significantly highest (1.32 per cent) leaf level of magnesium content was recorded in treatment N2P1K1F1 in the month of August at basal position, while it was lowest (0.07 per cent) with treatment combination N1POK0FO in the month of June at top position. Significant effect of different treatments were found on plant spread (Eastwest), stem girth, number of fruits/tree and fruit yield (kg/tree). Fruit yield was found highest in treatment N2P1K1F1 and it was lowest in treatment N1P1K0FO. The fruit yield (kg/tree) was significantly and positively correlated with number of fruits per tree, leaf level of N, P, K, Ca and Mg in different periods. More or less same trend was observed between number of fruits per tree with the said nutrient. There was significant and positive relationship between different leaf nutrients content and different periods. Despite the marked fluctuation of leaf nutrients throughout the year, stability period for nitrogen, phosphorus and magnesium were noted in the month of August to October; potassium in June to August and calcium in October to December. All these nutrients were found stabilized at middle position of indeterminate branch when samples were collected from middle position of tree. To assess nitrogen, phosphorus, potassium, calcium and magnesium status of aonla tree leaf sample should be collected from middle position of the tree during their respective stabilize period. Besides these, aonla trees requires to be applied N, P, and K alongwith FYM for higher yield.ThesisItem Open Access STUDIES ON NUTRIENT UPTAKE IN CORIANDER (Coriandrum sativum L.) UNDER DIFFERENT LEVELS OF FERTILIZATION(AAU, Anand, 1986) UGHREJA, P. P.; Chundawat, B. S.The present investigation on “Studies on nutrient uptake in Coriander (Coriandrum sativum L.) under different levels of fertilization’’ was carried out on two locations (i) Jagudan and (ii) Deesa, Gujarat Agricultural University, Sardar Krushinagar Campus under North Gujarat conditions in rabi season of 1984-85. The results revealed that fertilizer application significantly altered nutrient uptake leading to increased plant height, number of branches, number of umbels per plant, number of grains per primary umbel and grain weight which ultimately resulted into higher total grains per plant.
